  2. 2. Objectives  Introduction of FGT  Clinical manifestations of FGT pathology  Pathology of Valva  Pathology of Vagina  Pathology of Cervix  Pathology of Myometrium  Pathology of Endometrium  Pathology of Fallopian tube  Pathology of Ovary  Pathology Gestational and placental disorders
  3. 3. Female Reproductive System -The female reproductive system consists of -The ovaries -Secondary sex organs - which are involved in coitus, fertilization & development, birth & nursing of the baby. -
  4. 4. Major Organs of FGT  Vulva  Vagina  Cervix  Uterus  Uterine tubes [ fallopian tubes]  Ovaries ( The gonads )
  5. 5. DISEASES OF F.G.T. INCLUDE: -Diseases of the vulva -Diseases of the vagina -Diseases of the cervix -Diseases of the Body of Uterus And Endometrium -Diseases of the Fallopian tubes -Diseases of the Ovaries -Gestational and Placental disorders
  6. 6. Pathological basis of signs & symptoms in the FGT Sign or symptom Pathological basis -Vaginal discharge Inflammation -Vaginal bleeding In pregnancy Hemorrhage from placenta (placenta (praevia), placental bed (miscarriage) or decidua (ectopic pregnancy) Post-coital Hemorrhage from cervical lesion (carcinoma, erosion) Post-menopausal Hemorrhage from uterine
  7. 7. -Abnormal menstruation Psychological disturbance (timing or volume of loss) Hormonal dysfunction Defect in local haemostasis Uterine lesions (Fibroid,polyp, IUD) -Pain Pathologic distension/rupture (tubal ectopic pregnancy),Muscular spasm (uterine),Ischemia or infarction (ovarian torsion), menstrual pain due to adenomyosis, functional etc -Abdominal distension Ascites (Ovarian tumors involving peritoneum), uterine enlargement (pregnancy), ovarian cyst.
  8. 8. ABNORMAL UTERINE BLEEDING: The most common gynecologic problem in women during active reproductive life - Polymenorrhea: cycles shorter than 3 weeks - Oligomenorrhea: cycles longer than 6-7 weeks - Metrorrhagia: intermenstrual bleeding (MC organic ) - Hypermenorrhea: excessive flow (MC organic ) - Menorrhea: prolonged duration of flow - Menorrhagia: increase amount & duration of flow - Menometrorrhagia: prolonged flow with irregular intermittent spotting ( organic)
  9. 9. Causes of abnormal uterine bleeding according to age group Age group Causes Pre-puberty Precocious puberty ( hypothalamic, pituitary, or ovarian origin) Adolescence Anovulatory cycles , coagulation disorders Reproductive age - Complications of pregnancy ( abortion, ectopic pregnancy, trophoblastic diseases) - Organic lesions ( leiomyomas, adenomyosis, polyps, endometrial hyperplasia , carcinomas) - Anovulatory cycles -Ovarian dysfunctional bleeding (i.e. inadequate luteal phase) Perimenopausal -Anovulatory cycles - Irregular shedding Postmenopausal -Organiclesions ( carcinoma, hyperplasia, polyps) - Endometrial atrophy
  10. 10. DYSFUNCTIONAL UTERINE BLEEDING (FUNCTIONAL ENDOMETRIAL DISORDERS): Definition: It is abnormal bleeding in absence of organic uterine lesions. MCC is anovulatory cycles (hyperestrogenic states). It is due to: - Endocrine disorders - : pituitary, adrenal, and thyroid diseases. - Ovarian disorders - : polycystic ovaries, hormone secreting tumors. - Metabolic causes - : obesity, malnutrition,.. - Unexplained causes - : (?? Cryptogenic). Morphology: - Premenstrual endometrial biopsy shows a persistent proliferation pattern with variable degree of hyperplasia, cystic glandular change - Sporadic endometrial breakdown & bleeding ( estrogen effect unopposed by progesterone).
  11. 11. Diseases of Vulva
  12. 12.  Inflammatory lesion of Valva  Non neoplastic disorders  Tumours of Valva
  13. 13.  Inflammatory lesions of the Vulva:  All skin disorders can be seen  Herpes virus infection: STD, HSV type 2, Painful ulceration in the skin. Intraepithelial blisters & viral inclusion & eosinophilic swelling of epithelial cells  Syphilis:  Primary syphilis - : Chancer - indurated lesion with central ulceration & LN – heals even without Tt.  Secondary syphilis: Condyloma latum (inflammed hyperplasia of epithelium with underlying chronic inflammation rich in plasma cells & end arteritis obliterans), Silver stain demonstrates the spirochetes.
  14. 14. Genital Herpes
  15. 15. Primary syphilis: Chancer
  16. 16. Granuloma inguinale (Donovanosis): STD affecting the genitalia, inguinal & perianal region , gram negative bacilli (Calymmatobacterium donovani) - Chronic valvular papule/nodule/ ulceration, tropical areas, can spread to other parts of FGT, ulcer margins show epithelial hyperplasia & Ulcer bed filled with neutrophil abscesses. Sliver stain demonstrates bacilli within macrophages (Donovan bodies)
  17. 17. Lymphgranuloma venereum: STD, Chlamydia trachomatis, tropical areas, vesicles that rupture and form punched out painless ulcer, secondary infection, abundant granulation tissue, fibrosis, fistula, lymphatic obstruction (chronic form of the disease), necrotizing granuloma may occur
  18. 18. Candidiasis : Chronic irritation & inflammation, white thick discharge, DM, may be associated with vaginitis Diagnosis: ME of skin scrapping or culture, nonspecific histological picture, fungi can be demonstrated within the keratin layer or superficial epithelium by sliver stain Bartholin’sAbscessCyst: inflammatory occlusion of the main duct of Bartholin’s vulvo-vaginal gland, most common cause is gonorrhea Vulvodynia (vestibular adenitis) : inflammation of the minor vestibular glands (unkown cause) causing very painful ulceration. Treatment is often surgical.
  19. 19. Infection involving the lower and the upper genital tract (Pelvic inflammatory disease =PID) Definition: an ascending infection that begins in he vulva & spreads upward to involve the entire genital tract.
  20. 20. Causes: 1- Sexually transmitted disease (STD): gonococcal (MC) or chlamydial infection: acute suppurative inflammation confined to mucosa and submucosa (spread via mucosa). 2- Postabortal or postpartal; caused by staphylococci, streptococci, E. coli & clostridium perfringens. Spread is through uterine wall leading to affection of serosa and peritoneum.
  21. 21.  Morphology: acute suppurative inflammation of the Bartholin’s glands, periuretheral glands, endocervical glands & fallopian tubes.  Pathological lesions & complications: Acute salpingitis, salpingo-oophoritis, tubo-ovarian abscess, pyosalpinyx (distention of the fallopian tube with pus). It may cause peritonitis, septicemia, fibrous adhesion (intestinal obstruction), tubal occlusion & infertility or ectopic pregnancy.
  22. 22. *Non-neoplastic epithelial disorders (Vulvar Dystrophy- old name): Benign (non-dysplastic) mucosal alterations of the vulva; of unknown etiology predominantly in peri & postmenopausal periods Types: Two types that may coexist: G)Lichen Sclerosus et Atrophicus H)Lichen Simplex Chronicus
  23. 23. • Lichen Sclerosus et Atrophicus: gray, parchment-like areas, of thin atrophic epithelium + sube-pithelial fibrosis+ mononuclear peri-vascular reaction & occasionally marked hyperkeratosis. B) Lichen Simplex Chronicus (Squamous Hyperplasia = Hyperplastic Dystrophy): - It is the physiologic outcome to rubbing the vulva mucosa in response to pruritis . - PP causes: irritant exposure, dermatitis, pre-invasive or invasive neoplasm (biopsy is indicated) - Morphology: white plaques (leukoplakia) of thick hyperplastic & hyperkeratotic epithelium (without dysplasia) and leukocytic dermal inflammation. .
  24. 24. N.B.: Neither lichen sclerosus nor simplex chronicus is classified as premalignant per se, but cytogenetic abnormalities, including P53 mutations, may precede the onset of atypia in these lesions. Thus, they are considered “ Risk Factors” for vulvar neoplasia
  25. 25. TUMORS OF THE VULVA  Benign tumors ♦ Condyloma Accuminatum: ♦ Papillary Hidradenoma ♦ Vulvar Intraepithelial Neoplasia (VIN= Vulvar Dysplasia)  Malignant tumors ♦ Verrucous Carcinoma ♦ Invasive vulvar Squamous cell carcinoma ♦ Extramammary Paget’s Disease
  26. 26. Condyloma Accuminatum: multiple, benign, wart-like verrucous STD, caused by HPV types 6&11. (vulva, perineum, vagina, rarely cervix). It is squamous cell papilloma with marked acanthosis,hyperkeratosis & parakeratosis, some showing cells with cytoplasmic clearing and nuclear atypia (i.e. koilocytic atypia = koilocytosis indicating viral infection).
  27. 27. Papillary Hidradenoma: benign, well circumscribed nodule of modified apocrine sweat gland. It is composed of tubular structures lined by both epithelial(columner) & myoepithelial cells.
  28. 28.  Vulvar Intraepithelial Neoplasia (VIN= Vulvar Dysplasia): - A premalignant intramucosal squamous neoplasm that frequently precedes invasive carcinoma occurs 4th – 5th decades. - Mucosal lesions with cellular anaplasia and marked nuclear atypia, caused by HPV type 16. Synonyms: VIN III= carcinoma in situ (CIS)= Bowen’s disease. Tends to progress to invasive carcinoma ( in old & immunosuppressed patients). -
  29. 29.  Differentiate (simplex) VINs are usually HPV-negative, associated with Lichen sclerosus or Lichen simplex chronicus. These precancers usually arise after menopause and leading to well differentiated keratinized squamous cell carcinoma in the 6th – 8th decade.
  30. 30. N.B. HPV - E6 protein of HPV type 16 & 18 can bind to P53 gene leading to P53 inactivation - E7 protein of HPV 16 & 18 binds to Rb gene products Leading to promotion of neoplastic growth through: 1- deregulation of cell cycle 2- Production of genomic instability 3- Increase telomerase expression -Types 6 & 11 of HPV with no or low risk of malignancy do not form a complex with P53 & typically give rise to benign condylomas
  31. 31. Invasive vulvar Squamous cell carcinoma: may arise de novo or on top of VIN. Spreads to inguinal LNs & is of poor prognosis. The prognosis depends on size, depth of invasion, and lymph nodes status Verrucous Carcinoma: A rare locally aggressive neoplasm. Usually does not metastasize. ,
  32. 32.  Extramammary Paget’s Disease: - An eczyma-like, red crusted sharply demarcated map-like areas ( on labia majora), characterized by large anaplastic tumor cells, lying singly or in small groups within the epidermis. The cytoplasm of the tumor cells is clear, and mucin positive. - Unlike Paget’s disease of the breast, the presence of underlying adenocarcinoma of the vulva is uncommon. Other rare tumors: Basal cell carcinoma, Malignant melanoma
  33. 33. DISEASES OF VAGINA 1- Vginitis 2- Tumors of vagina
  34. 34. 1-Vaginitis & vulvovaginitis Since both vulva and vagina are anatomically close to each other, often inflammation of one affects the other. Common infections –  Bacterial - streptococci,staphalococci, E.coli, H. vaginalis  Protozoal - Trichomonas vaginalis  Viral - Herpes simplex  Fungal – Candida albicans The most common causes of vaginitis are Candida albicans ( monaliasis) and Trichomonas ( Trichomonaliasis )
  35. 35. TUMORS OF THE VAGINA  Benign tumors ♦ uncommon  Malignant tumors ♦ squamous cell carcinoma ♦ Clear cell adenocarcinoma ♦ Embryonal rhabdomyosarcoma
  36. 36. Carcinoma: primary carcinoma of the vagina is rare, but 1-2% women with cervical squamous cell carcinoma develop a concomitant squamous cell carcinoma in the vagina. Age: 60-70 yrs. Morphology; plaque-like, fungating /ulcerative lesion that infiltrates cervix, urethera, bladder or rectum. Clear cell adenocarcinoma: is rare (MC in young women, whose mothers had received Diethylstilbestrol (DES) during pregnacy for treatment of threatened abortion). The tumor cells are vacuolated and contained glycogen.
  37. 37.  Embryonal rhabdomyosarcoma:  uncommon, a highly malignant tumor of infants and children;  polypoid bulky mass (Botryoid= grape-like) protruding from vagina. That is why also known as Sarcoma Botroides
  38. 38. Histopathology  It is composed of rounded malignant (embryonal) rhabdomyoblasts, some tumor cells have a “tennis- racket” shape with striated cytoplastmic extension. Tumor cells are +ve for desmin & myosin immunostain. These cells are characterstically lying underneath the vaginal epithelium, called CAMBIUM LAYER  The central core of polypoid masses composed of loose and myxoid stroma with many inflammatory cella
  39. 39. Embryonal Rhabdomyosarcoma- vagina
  40. 40. DISEASES OF THE CERVIX  Inflammation of Cervix: Cervicitis  Cervical Tumors
  41. 41.  Inflammation of Cervix: Cervicitis - May be acute or chronic; specific or non-specific - Non-specific: Strept., Staph., enterococci, E. coli - Specific (STD): gonococci, Chlamydia, Mycoplasma, Trichomonas, Candida…. - Acute cervicitis: - rare (postpartal and nonspecific) - Neutrophilic infiltration beneath the lining mucosa
  42. 42. Chronic cervicitis: - More common Bacterial growth & alteration in pH - May be specific, non-specific or of unknown cause -- ----- - Common cause of leukorrhoea Predisposing factors – sexual intercourse, trauma of child birth, instrumentation and excess or deficiency of estrogen.
  43. 43. Morphology:  Gross- eversion of ectocervix with hyperemea, edema and granular surface.Nabothian(retention cysts) may be grossly visible as pearly grey vesicles.  Histopathology - squamous metaplasia, chronic inflammatory cells, columnar cell proliferation (micro- glandular change), reactive epithelial atypia (mistaken for CIN), and Nabothian cysts (due to occlusion of cervical gland ducts ) & squamous metaplasia
  44. 44. Normal epithelium of cervix & Chr. Cervicitis
  45. 45. Cervical Tumors  Benign tumors ♦ Endocervical polyp ♦ Cervical intraepithelial neoplasia (CIN)  Malignant tumors ♦ Invasive cervical carcinoma ♦ Adeno-squamous & Endocervical type Adenocarcinama
  46. 46. Cervical Tumors •Endocervical polyp: benign tumors composed of C.T. stroma showing dilated endocervical glands and lined by endocervical epithelium •Squamous intraepithelial lesions (SIL) CERVICAL INTRAEPITHELIAL NEOPLASIA(CIN) -It is caused by a sexually transmitted disease; 2nd – 3rd decades , caused by cancer-related (high risk) HPV type 16,18,31,33,35,39,51,52,53,56,58,59. - It usually precedes invasive squamous cell carcinoma (4th – 5th decades)
  47. 47. - Risk factors: early age of first intercourse, multiple sex partners & high-risk male sex partners; that suggests a sexually transmitted oncogenic agent from male to female at an early age. HPV acts as a promotor, and herpes virus type II , tobacco, constitution , environment & others may be cofactors.
  48. 48.  Morpholgy: CIN I = dysplasia in the deeper 1/3rd of the epithelium & preserved maturation in the upper 2/3rd. CIN II = dysplasia in the deeper 2/3rd & less maturation. CIN III = dysplasia in all layers & no maturation i.e carcinoma in situ (CIS)
  49. 49. Normal Cervical lining & CIN I, II & III
  50. 50. Bethesda system : a new classification for CIN (National Cancer Institute) for reporting cervical & vaginal cytology. Besthesda HPV Morphology CIN Dysplasia system type -Low grade SIL 6,11 Koilocytic atypia, flat CIN I Mild (L-SIL) – condyloma -High grade SIL Progressive cellular 16,18 CIN II Moderate, (H-SIL) atypia , loss of & CIN severe, maturation III carcinoma in situ N.B.: The oncoproteins (E6 &E7) of high-risk HPVs deregulate the cell cycle, produce genomic instability, and increase telomerase expression. All these molecular events promote neoplastic cell growth. The low risk HPVs (HPV 6,11) do not possess these properties and typically give rise to benign condyloma. L-SIL –Low grade – Sq. Intraepithelial Lesion
  51. 51. INVASIVE CERVICAL CARCINOMA: -Up to 70% of CIN III (CIS) progress to invasive carcinoma. -Gross: fungating, ulcerative or infiltrative lesions -Histology: most cases are squamous cell carcinoma of varying degree of differentiation (65% = large cell non-keratinizing, 25% large cell keratinizing, 10% small cell poorly differentiated sq.c.c.) -Other non-squamous carcinomas (adenocarcinoma, adenosquamous, neuroendocrine=small cell undifferentiated) are less common and strongly associated with HPV type 18.
  52. 52. Adeno-squamous & Endocervical type Adenocarcinama - Cervix
  53. 53.  Clinical staging: - Stage 0: CIS Stage I: confined to the cervix - Stage II: extending beyond the cervix but not into - the pelvic wall; into vagina but not to - lower 1/3 of vagina - Stage III: reaching the pelvic wall or lower 1/3 of - vagina - Stage IV: spreading out side the pelvis  Prognosis: depends on stage ( 100% cure for stage 0 & 10% of stage IV).
  54. 54. DISEASES OF THE ENDOMETRIUM  ENDOMETRITIS:  ADENOMYOSIS & ENDOMETRIOSIS:  ENDOMETRIAL HYPERPLASIA  TUMORS OF THE ENDOMETRIUM
  55. 55. ENDOMETRITIS:  Acute endometritis: Histological : Neutrophilic infiltration of the endometrium, caused by Staph., Strept., …; following abortion, delivery or instrumentation.  Chronic endometritis: Clinically : Abnormal endometrial bleeding Histological : Mononuclear (plasma cell & macrophages infiltration of the endometrium. Etiology : in chronic PID, tuberculous, in user of IUDs, actinomycosis and due to retained gestational tissue.
  56. 56. ADENOMYOSIS & ENDOMETRIOSIS: Adenomyosis : Defined as presence of nests of benign endometrial glands & stroma within the myometrium, deep in the wall of the uterus. It leads to uterine enlargement & irregular thickening of the uterine wall. -Possible cause – metaplasia or oestrogenic stimulation due to endocrine dysfunction of ovary -Clinically- menorrhagia, colicky dismenorrheoa and menstrual pain in the sacral or sacrococcycygeal regions. - Critaria for diagnosis – The minimum distance between the endometrial islands within the myometrium and the basal endometrium should be one low power microscopic field (2-3 mm ).
  57. 57. Adenomyosis
  58. 58. Endometriosis: - Presence of nests of endometrial glands & or stroma outside the uterus in ovaries, fallopian tubes, pelvic peritoneum, uterine ligaments, and rarely in vulva, vagina, laparotomy scar, umbilicus, and appendix. - Ectopic endometrium may undergo cyclic menstrual changes and periodic bleeding. - Clinically: dysmenorrhea, dyspareunia , pelvic pain & infertility. - Diagnosis depends on the presence of 2 out of 3 following features : 1- Endometrial glands , 2-Stroma, and 3- RBCs or hemosiderin pigment.
  59. 59. Theories of endometriosis: - Tubal spread - Lymphatic spread - Hematogenous spread
  60. 60. ENDOMETRIAL INTRAEPITHELIAL NEOPLASIA = EIN ( ENDOMETRIAL HYPERPLASIA ) Definition: It is abnormal proliferation of endometrial glands. The most common cause of dysfunctional uterine bleeding (DUB) & is associated with hyperestrogenemia.
  61. 61. Types: 1- Simple hyperplasia= cystic hyperplasia, mild hyperplasia: Cystic dilated glands, non-neoplastic, due to anovulatory cycles. 2- Complex hyperplasia= adenomatous hyperplasia: Overcrowded, closely opposed glands. Some of these are neoplastic (contain PTEN (Phosphatase and tensin homolog ) mutations & considered as EIN). PTEN- tumor suppressor gene 3-Atypical hyperplasia = complex / adenomatous hyperplasia with atypia: Overcrowded glands with cytological atypia. Most cases of this category are neoplastic (EIN) and many contain PTEN mutations
  62. 62. N.B.: Endometrial hyperplasia: - It is an important cause of abnormal uterine bleeding. - A subset (EIN) is considered a risk factor for endometrial carcinoma. -The risk of carcinoma increases as function of the degree of atypia. - Both endometrial hyperplasia and adenocarcinoma are associated with hyperestrogenism, microsatellite instability, and mutation of PTEN gene.
  63. 63. Simple (cystic)glandular hyperplasia Complex (adenomtous) hyperplasia without atypia Complex (adenomatous) hyerplasia with atypia
  64. 64. TUMORS OF THE ENDOMETRIUM  Benign tumors ♦ Endometrial polyp  Malignant tumors ♦ Endometrial carcinoma ♦ Papillary serous adenocarcinoma ♦ ENDOMETRIAL STROMAL SRCOMA (MALIGNANT MIXED MESODERMAL=MULLERIAN TUMOR)
  65. 65. TUMORS OF THE ENDOMETRIUM Endometrial polyp: - Sessile tumors composed of endometrial glands and stroma. - May be associated with hyperestrogenism or Tamoxifen therapy. - Usually benign, but may show foci of hyperplasia or cancer.
  66. 66. Endometrial carcinoma: - 7% of all invasive carcinomas in women - Most common invasive cancer of the female genital tract. Epidemiologic & pathophysiologic types: 1- Endometrial adenocarcinoma: Common,55-65 yrs. Old. - Risk factors: Obesity, nulliparity, early menarche & late menopause, granulosa cell tumor of the ovary, breast cancer, diabetes, hypertension,infertility&unopposed estrogen.. -
  67. 67.  Gross: Fungating polypoid or infiltrating mass (diffuse involving the entire endometrial surface). - Histopathology: Adenocarcinoma usually well differentiated with often associated with metaplastic changes ( squamous, secretory or mucinous differentiation). Other histological forms: adenosquamous or clear cell adenocarcinoma. - Containing mutations in PTEN gene, microsatellite instability, often pre-exciting EIN.
  68. 68. 2) Papillary serous adenocarcinoma: - Associated with older age , - Often arising in endometrial polyps or endometrial surface epithelium, and - Associated with multiple P53 mutations. -Spread: invades the myometrium, and spread by lymphatics & blood (MC to the lung). Serous tumors can spread quickly, even when non-invasive
  69. 69. - Prognosis: depends on extend of spread (stage). Excellent prognosis when the carcinoma is confined to corpus uteri itself. However papillary serous tumor spreads quickly even when non-invasive. Biologically: more aggressive neoplasms are poorly differentiated carcinomas including clear cell & papillary serous carcinoma. Clinically Abnormal uterine bleeding
  70. 70. ENDOMETRIAL STROMAL SRCOMA ( MALIGNANT MIXED MESODERMAL = MULLERIAN TUMOR ): TUMORS WITH STROMAL DIFFERENTIATION -Rare tumors. Highly malignant. Derived from primitive stromal cells (mullerian mesoderm origin). Consists of glandular (carcinomatous) & stromal (sarcomatous) elements. The stromal elements may show muscle, cartilage or osteoid differentiation. --Gross: bulky polypoid tumor protruding into endometrial cavity and vagina.
  71. 71. - Other variants of endometrial stromal tumors:  1)Benign stromal nodules: discrete nodules of stromal neoplasm within the myometrium.  2)Endometrial stromal sarcoma (Endolymphatic stromal myosis): well & poorly differentiated stromal neoplasm, may penetrate into lymphatic channels.  3)High-grade sarcoma not otherwise specified: high grade unclassified tumor capable of widespread metastases. Occurs in postmenopausal females; presents with uterine bleeding. Overall 5- years survival is 25%.
  72. 72. TUMORS OF THE MYOMETRIUM  Benign tumors ♦ Leiomyoma  Malignant tumors ♦ Leiomyosarcoma
  73. 73. Leiomyoma: -Benign smooth muscle tumor, MC overall tumor of females in the active reproductive age, related to increased estrogen stimulation, and associated with a number of specific cytogenetic abnormalities. - Sharply circumscribed, round gray-white firm nodules, located - 1-within the myometrium (intramural), 2-beneath the serosa (subserous) 3-beneath the endometrium (submucous).
  74. 74.  It may undergo cystic degeneration and calcification. - May be asymptomatic or associated with abnormal uterine bleeding, pain, urinary disorders. - Malignant transformation is exceptionally rare (? almost none).
  75. 75. LEIOMYOSARCOMA -: - Uncommon, most arise de novo and not from leiomyomas. - Bulky, fleshy, infiltrative mass in the uterine wall -Disseminate in the peritoneal cavity & widely by blood stream. - Overall 5-years survival is 40%
  76. 76. Histologically distinguished from leiomyomas by: 1- More than 10 mitotic figures/ 10 H.P.F. ( with or without cellular atypia), or 2- Between 5-10 mitotic figures with cellular atypia. N.B.: Smooth muscle tumor of uncertain malignant potential: A subset of smooth muscle tumors displays some but not all of the features of malignancy
  77. 77. DISEASES OF THE FALLOPIAN TUBES  1-INFLAMMATORY - SALPINGITIS:  2- TUMORS OF FALLOPIAN TUBE-
  78. 78. 1-INFLAMMATORY - SALPINGITIS: Suppurative salpingitis: -Infection by pyogenic organisms: streptococci, staphylococci, & gonococci (PID) -May cause tubo-ovarian abscesses, pyosalpinx, peritonitis & “violin string” adhesion that may cause intestinal obstruction. Tuberculous salpingitis: -Hematogenous dissimination from other foci . May be associated with T.B. of endometrium & peritoneum. Histologically: caseating granulomas with giant cells. -May cause infertility, or ectopic pregnancy
  79. 79. TUMORS OF FALLOPIAN TUBE  Benign tumors ♦ Uncommon  Malignant tumors ♦ Adenocarcinoma
  80. 80. 2- TUMORS OF FALLOPIAN TUBE- - Rare. Most common is adenocarcinoma (like serous adenocarcinoma of the ovary). - Recently, adenocarcinoma of the fallopian tubes has been associated with BRCAI & BRCA 2 mutations?. - Many arise in the fimbriated portion of the tube.
  81. 81. PATHOLOGY OF OVARY
  82. 82. OVARY  Anatomy  Manifestations of ovarian diseases  Inflammatory - Oophritis  Non-Neoplastic Ovarian Cysts  Ovarian Tumors  Classification of ovarian tumors  Pathology of individual tumors
  83. 83. Normal Structure
  84. 84. Embryological development Precursor Ovarian component Other female genital tract structures 1.Coelomic epithelium Surface epithelium 1.Fallopian tubes( ciliated 2. Ectopic endometrial columnar serous cells) epithelium—Mullerian 2.Endometrial lining(non Epithelium ciliated columnar cells) 3. Endocervical glands (mucinous non ciliated) 1.Yolk Sac Germ cells(toti potent) 1. Sex cords Stroma of the ovary Endocrine apparatus of post natal ovary.
  85. 85. Importance of embryological development 1.Primary Ovarian tumours are classified on the basis of their site of origin. 2.Still some tumours do not fall in any of the categories and are put into Malignant (Not Otherwise Specified) 3.A third category of neoplasms of the ovary are Metastatic tumours from non ovarian primaries.
  86. 86. OVARIAN DISEASES Manifestations of ovarian diseases: - Pelvic pain - Menstrual irregularities ( abnormal pattern of ovarian hormone secretion). - Infertility; failure of ovulation (Stein-Leventhal). - Ovarian mass : either non-neoplastic (cysts) or neoplastic (cystic or solid).
  87. 87.  INFLAMMATORY - OOPHORITIS: - Inflammation of the ovaries is always secondary to salpingitis or peritonitis. - If chronic & bilateral leading to extensive fibrosis & infertility.
  88. 88.  NON-NEOPLASTIC OVARIAN CYSTS 1- Follicular and Luteal cysts: Common, 1-8 cm in diameter. They are lined by follicular (granulosa) cells or luteinized cells. Asymptomatic, but may rupture, causing peritoneal reaction & pain. 2 - Chocolate cysts: Blood-filled cysts, due to endometriosis of the ovaries.
  89. 89. 3 – Polycystic ovarian ( Stein - Leventhal syndrome (PCOD) -: It is important cause of infertility. There is excessive production of androgens, increase conversion of androgens to estrogen, insulin resistance, and inappropriate gonadotrophin production by the pituitary. Morphology: Ovaries are large, white, many subcortical follicular cysts(0.5-1 cm.) in diameter, and covered by thickened fibrosed outer tunica. No corpora lutea (= no ovulation). Manifestations: Young females with Oligomenorrhea, infertility, obesity & hirsuitism.
  90. 90. POLYCYSTIC OVARY
  91. 91. OVARIAN TUMORS - Common forms of neoplasia in women. - 80-90% of ovarian tumors are benign. - Most ovarian tumors occur between 20-45 years. - Ovarian cancer is second MC malignancy of the female genital tract (after endometrial cancer). - Most ovarian tumors are derived from surface epithelium, and “CA-125” is the tumor marker for surface epithelial tumors of the ovary. - Malignant ovarian tumors present at a late stage, thus are associated with high mortality rate. - Known risk factors are nulliparity, family history, and specific inherited mutations (BRCAI & BRCAII) genes.

  97. 97. SEROUS TUMORS -The MC cystic neoplasms of the ovary. - Cysts are lined by tall columnar, ciliated epithelial cells (fallopian tube type) & filled with serous fluid. Types: 1-Benign Serous Tumors (Cystadenomas): (60%), smooth lining & no papillary or solid areas. 20% are bilateral. 2- Borderline Serous Tumors (low malignant potential): (15%), epithelial atypia, solid areas, but no stromal invasion. 30% are bilateral. 3- Malignant Serous Tumors (Cystadenocarcinomas): (25%); multilayered epithelium, solid areas & papillary structures invasing the stroma. 65% are bilateral. The prognosis depends on stage, and the presence of peritoneal implants means poor prognosis.

They either lined by tall columnar mucus-secreting epithelium (intestinal-type mucinous cystomas) or show papillary architectures and focal cilia (mullerian mucinous tumors), which may be associated with endometriosis. Types: 1- Benign Mucinous Tumors (cystadenomas): 80%; large cysts with smooth lining & no atypia. 5% are bilateral. 2- Borderline Mucinous Tumors (of low malignant potential): 10-15%; cellular atypia, but no stromal invasion. 3- Malignant Mucinous Tumors (Cystadenocarcinomas): 5-10%; atypia, solid sheets & stromal invasion. 20% bilateral. Seeding in the peritoneum with malignant deposits causes pseudomyxoma peritonei. Usually mucinous cystadenocarcinomas are of intestinal type.

  134. 134. GESTATIONAL & PLACENTAL DISORDERS
  135. 135. ECTOPIC PREGNANCY : Disorders of early pregnancy Definition: implantation of the embryo in any site other than uterus; Most common- the fallopian tube (> 90%), rarely in ovary or abdominal cavity. Associated with PID & endometriosis; but 50% occur with no known cause.
  136. 136.  May end in:  1- Spontaneous regression with resorption of the products of conception  2- Intratubal hemorhage (hematosalpinx)  3- Tubal abortion or rupture & extrusion into abdominal cavity →  intraperitoneal hemorrhage and shock i.e. acute abdomen  (medical emergency). - Diagnosis:  High hCG, sonography & endometrial biopsy showing decidual reaction but no chorionic villi.
  137. 137. Disorders of late pregnancy 1- Placental inflammation or infection: A) Disorder of ascending infection (Chorioamnionitis): - infection of the fetal membrane - Usually ascending from the vagina, in case of premature rupture of the membranes. - Most common cause is group B streptococci. - Acute suppurative inflammation of the chorion & amnion, and acute vasculitis of the umbilical cord (funisitis). B) Hematogenous (transplacental ) infection: - It is derived from maternal septicemia (Listeria, streptococcus & TORCH = Toxoplasma, Rubella, Syphilis, Cytomegalovirus, Herpes) → villous inflammation (villitis) and acute intervillositis.
  138. 138. 2- Toxemia of pregnancy: -Occurs in 6% of pregnancies, in the last trimester & most common in primiparas. 1- Pre-eclaspia = hypertension , proteinuria & edema, headache & visual disturbances 2- Eclampsia = severe pre-eclapsia + convulsions & coma. Associated with widespread endothelial injury & DIC (Desseminated Intravascular Coagulation) affecting kidneys, liver, brain & other organs. - Resembles GVH( Graft Versus Host Reaction , but etiopathogenesis is poorly understood. - Delivery is the only definitive treatment for pre-eclampsia and eclampsia. Pathogenesis of Toxemia of pregnancy: Unclear; - The primary cause may be immune or genetic factors → mechanical or functional obstruction of the uterine spiral arterioles → placental ischemia → endothelial injury & activation of disseminated intravascular coagulation, leading to decrease in glomerular filtrate, CNS disturbances, abnormal liver functions, and fibrin thrombi and ischemia in most organs.
  139. 139. THEORIES OT TOXEMIA OF PREGNANCY: 1- Inadequate placental implantation → decrease in uteroplacental perfusion and placental ischemia → increase production of vasoconstrictors (e.g. thromboxane , angiotensin) & decrease of vadodilators(e.g. prostaglandin I2, prostaglandin E2) → arteriolar vasocontriction & hypertension. 2- Recently ; Factors imbalance → premature termination of placental vascular growth. There is abnormal increase in an anti-angiogenic factor (sflt-1) and reduction in pro-angiogenic factors (Vascular endothelial-derived growth factor= VEGF & placental growth factor =PLGF ).
  140. 140. GESTATIONAL TROPHOBLASTIC DISEASES 1- HYADATIDIFORM (VESICULAR) MOLE: defined by- 1- Enlarged edematous and hydropic change of chorionic villi which become vesicular(Cystic swelling). Gross -Grape like 2-Variable trophoblastic proliferation. Two types: - Complete (diploid) & - Partial/Incomplete (triploid). - 10% develop into invasive mole, and 2.5% develop into choriocarcinoma. 2- INVASIVE MOLE: - Penetrates the uterine wall, produce hemorrhage but does not metastasize. - Responds well to chemotherapy.
  141. 141. Feature Complete mole Partial mole -Karyotype -Diploid (46 xxor 46xy), two sperms -Triploid(69 ). Two sperms fertilize an egg fertilize an empty egg. All genetic with normal chromosomes material is paternal -Rarely seen or absent - Fetal parts - Usually present with abnormalities - All villi - Some villi - Villous edema - Diffuse & circumferential - Focal and slight - Trophoblastic proliferation - Atypia -Often present -Abscent -Serum hCG - Elevated - less elevated -hCG in tissue - ++++ - + - Behavior - 2% choriocarcinoma - Rare choriocarcinoma
  142. 142. 3- Choriocarcinoma: - 50% follow hydatidiform mole & 25% follow normal pregnancy, 20% follow abortion & 5% follow ectopic pregnancy. - Highly malignant & metastasize widely. -Gross: Large, soft, yellowish white & fleshy with areas of hemorrhage and necrosis. -Histology: Abnormal proliferation of both cytotrophoblasts & cyncytiotrophoblasts invading the endometrium, blood vessels, lymphatics, no chorionc villi are seen. - Spread: To lung, bone marrow, liver & other organs.
  143. 143. Clinical features: Vaginal bleeding & discharge in the course of apparently normal prgnancy, after miscarriage, or high hCG titers. N.B.: All gestational trophoblastic disorders are associated with high level of hCG (tumor marker).
  144. 144. 4- Placental site trophoblastic Tumor: - A rare tumor composed of proliferating intermediate trophoblasts (larger than cytotrophoblasts but mononuclear than cyncytial). - D.D. from choriocarcinoma by the absence of cytotrophoblastic elements and low level of hCG production. - Mostly are locally invasive only, but malignant variants are distinguished by: - A high mitotic index, - Extensive necrosis, and - local spread. - About 10% result in metastases and death.

Editor's Notes

  • Each month the uterus goes through a cyclical change, first building up its endometrium or inner lining to receive a fertilized egg, then, if conception does not occur, shedding the unused tissue through the vagina in the monthly process called menstruation

    8. 8. ABNORMAL UTERINE BLEEDING: The most common gynecologic problem in women during active reproductive life - Polymenorrhea: cycles shorter than 3 weeks - Oligomenorrhea: cycles longer than 6-7 weeks - Metrorrhagia: intermenstrual bleeding (MC organic ) - Hypermenorrhea: excessive flow (MC organic ) - Menorrhea: prolonged duration of flow - Menorrhagia: increase amount & duration of flow - Menometrorrhagia: prolonged flow with irregular intermittent spotting ( organic)
    9. 9. Causes of abnormal uterine bleeding according to age group Age group Causes Pre-puberty Precocious puberty ( hypothalamic, pituitary, or ovarian origin) Adolescence Anovulatory cycles , coagulation disorders Reproductive age - Complications of pregnancy ( abortion, ectopic pregnancy, trophoblastic diseases) - Organic lesions ( leiomyomas, adenomyosis, polyps, endometrial hyperplasia , carcinomas) - Anovulatory cycles -Ovarian dysfunctional bleeding (i.e. inadequate luteal phase) Perimenopausal -Anovulatory cycles - Irregular shedding Postmenopausal -Organiclesions ( carcinoma, hyperplasia, polyps) - Endometrial atrophy

MCC is anovulatory cycles (hyperestrogenic states). It is due to: - Endocrine disorders - : pituitary, adrenal, and thyroid diseases. - Ovarian disorders - : polycystic ovaries, hormone secreting tumors. - Metabolic causes - : obesity, malnutrition,.. - Unexplained causes - : (?? Cryptogenic). Morphology: - Premenstrual endometrial biopsy shows a persistent proliferation pattern with variable degree of hyperplasia, cystic glandular change - Sporadic endometrial breakdown & bleeding ( estrogen effect unopposed by progesterone).
    11. 11. Diseases of Vulva

    13. 13.  Inflammatory lesions of the Vulva:  All skin disorders can be seen  Herpes virus infection: STD, HSV type 2, Painful ulceration in the skin. Intraepithelial blisters & viral inclusion & eosinophilic swelling of epithelial cells  Syphilis:  Primary syphilis - : Chancer - indurated lesion with central ulceration & LN – heals even without Tt.  Secondary syphilis: Condyloma latum (inflammed hyperplasia of epithelium with underlying chronic inflammation rich in plasma cells & end arteritis obliterans), Silver stain demonstrates the spirochetes.
    14. 14. Genital Herpes
    15. 15. Primary syphilis: Chancer
    16. 16. Granuloma inguinale (Donovanosis): STD affecting the genitalia, inguinal & perianal region , gram negative bacilli (Calymmatobacterium donovani) - Chronic valvular papule/nodule/ ulceration, tropical areas, can spread to other parts of FGT, ulcer margins show epithelial hyperplasia & Ulcer bed filled with neutrophil abscesses. Sliver stain demonstrates bacilli within macrophages (Donovan bodies)
    17. 17. Lymphgranuloma venereum: STD, Chlamydia trachomatis, tropical areas, vesicles that rupture and form punched out painless ulcer, secondary infection, abundant granulation tissue, fibrosis, fistula, lymphatic obstruction (chronic form of the disease), necrotizing granuloma may occur
    18. 18. Candidiasis : Chronic irritation & inflammation, white thick discharge, DM, may be associated with vaginitis Diagnosis: ME of skin scrapping or culture, nonspecific histological picture, fungi can be demonstrated within the keratin layer or superficial epithelium by sliver stain Bartholin’sAbscessCyst: inflammatory occlusion of the main duct of Bartholin’s vulvo-vaginal gland, most common cause is gonorrhea Vulvodynia (vestibular adenitis) : inflammation of the minor vestibular glands (unkown cause) causing very painful ulceration. Treatment is often surgical.
    19. 19. Infection involving the lower and the upper genital tract (Pelvic inflammatory disease =PID) Definition: an ascending infection that begins in he vulva & spreads upward to involve the entire genital tract.
    20. 20. Causes: 1- Sexually transmitted disease (STD): gonococcal (MC) or chlamydial infection: acute suppurative inflammation confined to mucosa and submucosa (spread via mucosa). 2- Postabortal or postpartal; caused by staphylococci, streptococci, E. coli & clostridium perfringens. Spread is through uterine wall leading to affection of serosa and peritoneum.
    21. 21.  Morphology: acute suppurative inflammation of the Bartholin’s glands, periuretheral glands, endocervical glands & fallopian tubes.  Pathological lesions & complications: Acute salpingitis, salpingo-oophoritis, tubo-ovarian abscess, pyosalpinyx (distention of the fallopian tube with pus). It may cause peritonitis, septicemia, fibrous adhesion (intestinal obstruction), tubal occlusion & infertility or ectopic pregnancy.
    22. 22. *Non-neoplastic epithelial disorders (Vulvar Dystrophy- old name): Benign (non-dysplastic) mucosal alterations of the vulva; of unknown etiology predominantly in peri & postmenopausal periods Types: Two types that may coexist: G)Lichen Sclerosus et Atrophicus H)Lichen Simplex Chronicus
    23. 23. • Lichen Sclerosus et Atrophicus: gray, parchment-like areas, of thin atrophic epithelium + sube-pithelial fibrosis+ mononuclear peri-vascular reaction & occasionally marked hyperkeratosis. B) Lichen Simplex Chronicus (Squamous Hyperplasia = Hyperplastic Dystrophy): - It is the physiologic outcome to rubbing the vulva mucosa in response to pruritis . - PP causes: irritant exposure, dermatitis, pre-invasive or invasive neoplasm (biopsy is indicated) - Morphology: white plaques (leukoplakia) of thick hyperplastic & hyperkeratotic epithelium (without dysplasia) and leukocytic dermal inflammation. .
    24. 24. N.B.: Neither lichen sclerosus nor simplex chronicus is classified as premalignant per se, but cytogenetic abnormalities, including P53 mutations, may precede the onset of atypia in these lesions. Thus, they are considered “ Risk Factors” for vulvar neoplasia
    25. 25. TUMORS OF THE VULVA  Benign tumors ♦ Condyloma Accuminatum: ♦ Papillary Hidradenoma ♦ Vulvar Intraepithelial Neoplasia (VIN= Vulvar Dysplasia)  Malignant tumors ♦ Verrucous Carcinoma ♦ Invasive vulvar Squamous cell carcinoma ♦ Extramammary Paget’s Disease
    26. 26. Condyloma Accuminatum: multiple, benign, wart-like verrucous STD, caused by HPV types 6&11. (vulva, perineum, vagina, rarely cervix). It is squamous cell papilloma with marked acanthosis,hyperkeratosis & parakeratosis, some showing cells with cytoplasmic clearing and nuclear atypia (i.e. koilocytic atypia = koilocytosis indicating viral infection).
    27. 27. Papillary Hidradenoma: benign, well circumscribed nodule of modified apocrine sweat gland. It is composed of tubular structures lined by both epithelial(columner) & myoepithelial cells.
    28. 28.  Vulvar Intraepithelial Neoplasia (VIN= Vulvar Dysplasia): - A premalignant intramucosal squamous neoplasm that frequently precedes invasive carcinoma occurs 4th – 5th decades. - Mucosal lesions with cellular anaplasia and marked nuclear atypia, caused by HPV type 16. Synonyms: VIN III= carcinoma in situ (CIS)= Bowen’s disease. Tends to progress to invasive carcinoma ( in old & immunosuppressed patients). -
    29. 29.  Differentiate (simplex) VINs are usually HPV-negative, associated with Lichen sclerosus or Lichen simplex chronicus. These precancers usually arise after menopause and leading to well differentiated keratinized squamous cell carcinoma in the 6th – 8th decade.
    30. 30. N.B. HPV - E6 protein of HPV type 16 & 18 can bind to P53 gene leading to P53 inactivation - E7 protein of HPV 16 & 18 binds to Rb gene products Leading to promotion of neoplastic growth through: 1- deregulation of cell cycle 2- Production of genomic instability 3- Increase telomerase expression -Types 6 & 11 of HPV with no or low risk of malignancy do not form a complex with P53 & typically give rise to benign condylomas
    31. 31. Invasive vulvar Squamous cell carcinoma: may arise de novo or on top of VIN. Spreads to inguinal LNs & is of poor prognosis. The prognosis depends on size, depth of invasion, and lymph nodes status Verrucous Carcinoma: A rare locally aggressive neoplasm. Usually does not metastasize. ,
    32. 32.  Extramammary Paget’s Disease: - An eczyma-like, red crusted sharply demarcated map-like areas ( on labia majora), characterized by large anaplastic tumor cells, lying singly or in small groups within the epidermis. The cytoplasm of the tumor cells is clear, and mucin positive. - Unlike Paget’s disease of the breast, the presence of underlying adenocarcinoma of the vulva is uncommon. Other rare tumors: Basal cell carcinoma, Malignant melanoma
    33. 33. DISEASES OF VAGINA 1- Vginitis 2- Tumors of vagina
    34. 34. 1-Vaginitis & vulvovaginitis Since both vulva and vagina are anatomically close to each other, often inflammation of one affects the other. Common infections –  Bacterial - streptococci,staphalococci, E.coli, H. vaginalis  Protozoal - Trichomonas vaginalis  Viral - Herpes simplex  Fungal – Candida albicans The most common causes of vaginitis are Candida albicans ( monaliasis) and Trichomonas ( Trichomonaliasis )
    35. 35. TUMORS OF THE VAGINA  Benign tumors ♦ uncommon  Malignant tumors ♦ squamous cell carcinoma ♦ Clear cell adenocarcinoma ♦ Embryonal rhabdomyosarcoma
    36. 36. Carcinoma: primary carcinoma of the vagina is rare, but 1-2% women with cervical squamous cell carcinoma develop a concomitant squamous cell carcinoma in the vagina. Age: 60-70 yrs. Morphology; plaque-like, fungating /ulcerative lesion that infiltrates cervix, urethera, bladder or rectum. Clear cell adenocarcinoma: is rare (MC in young women, whose mothers had received Diethylstilbestrol (DES) during pregnacy for treatment of threatened abortion). The tumor cells are vacuolated and contained glycogen.
    37. 37.  Embryonal rhabdomyosarcoma:  uncommon, a highly malignant tumor of infants and children;  polypoid bulky mass (Botryoid= grape-like) protruding from vagina. That is why also known as Sarcoma Botroides
    38. 38. Histopathology  It is composed of rounded malignant (embryonal) rhabdomyoblasts, some tumor cells have a “tennis- racket” shape with striated cytoplastmic extension. Tumor cells are +ve for desmin & myosin immunostain. These cells are characterstically lying underneath the vaginal epithelium, called CAMBIUM LAYER  The central core of polypoid masses composed of loose and myxoid stroma with many inflammatory cella
    39. 39. Embryonal Rhabdomyosarcoma- vagina
    40. 40. DISEASES OF THE CERVIX  Inflammation of Cervix: Cervicitis  Cervical Tumors
    41. 41.  Inflammation of Cervix: Cervicitis - May be acute or chronic; specific or non-specific - Non-specific: Strept., Staph., enterococci, E. coli - Specific (STD): gonococci, Chlamydia, Mycoplasma, Trichomonas, Candida…. - Acute cervicitis: - rare (postpartal and nonspecific) - Neutrophilic infiltration beneath the lining mucosa
    42. 42. Chronic cervicitis: - More common Bacterial growth & alteration in pH - May be specific, non-specific or of unknown cause -- ----- - Common cause of leukorrhoea Predisposing factors – sexual intercourse, trauma of child birth, instrumentation and excess or deficiency of estrogen.
    43. 43. Morphology:  Gross- eversion of ectocervix with hyperemea, edema and granular surface.Nabothian(retention cysts) may be grossly visible as pearly grey vesicles.  Histopathology - squamous metaplasia, chronic inflammatory cells, columnar cell proliferation (micro- glandular change), reactive epithelial atypia (mistaken for CIN), and Nabothian cysts (due to occlusion of cervical gland ducts ) & squamous metaplasia
    44. 44. Normal epithelium of cervix & Chr. Cervicitis
    45. 45. Cervical Tumors  Benign tumors ♦ Endocervical polyp ♦ Cervical intraepithelial neoplasia (CIN)  Malignant tumors ♦ Invasive cervical carcinoma ♦ Adeno-squamous & Endocervical type Adenocarcinama
    46. 46. Cervical Tumors •Endocervical polyp: benign tumors composed of C.T. stroma showing dilated endocervical glands and lined by endocervical epithelium •Squamous intraepithelial lesions (SIL) CERVICAL INTRAEPITHELIAL NEOPLASIA(CIN) -It is caused by a sexually transmitted disease; 2nd – 3rd decades , caused by cancer-related (high risk) HPV type 16,18,31,33,35,39,51,52,53,56,58,59. - It usually precedes invasive squamous cell carcinoma (4th – 5th decades)
    47. 47. - Risk factors: early age of first intercourse, multiple sex partners & high-risk male sex partners; that suggests a sexually transmitted oncogenic agent from male to female at an early age. HPV acts as a promotor, and herpes virus type II , tobacco, constitution , environment & others may be cofactors.

Etiology : in chronic PID, tuberculous, in user of IUDs, actinomycosis and due to retained gestational tissue.
    56. 56. ADENOMYOSIS & ENDOMETRIOSIS: Adenomyosis : Defined as presence of nests of benign endometrial glands & stroma within the myometrium, deep in the wall of the uterus. It leads to uterine enlargement & irregular thickening of the uterine wall. -Possible cause – metaplasia or oestrogenic stimulation due to endocrine dysfunction of ovary -Clinically- menorrhagia, colicky dismenorrheoa and menstrual pain in the sacral or sacrococcycygeal regions. - Critaria for diagnosis – The minimum distance between the endometrial islands within the myometrium and the basal endometrium should be one low power microscopic field (2-3 mm ).

Types: 1- Simple hyperplasia= cystic hyperplasia, mild hyperplasia: Cystic dilated glands, non-neoplastic, due to anovulatory cycles. 2- Complex hyperplasia= adenomatous hyperplasia: Overcrowded, closely opposed glands. Some of these are neoplastic (contain PTEN (Phosphatase and tensin homolog ) mutations & considered as EIN). PTEN- tumor suppressor gene 3-Atypical hyperplasia = complex / adenomatous hyperplasia with atypia: Overcrowded glands with cytological atypia. Most cases of this category are neoplastic (EIN) and many contain PTEN mutations

Associated with widespread endothelial injury & DIC (Desseminated Intravascular Coagulation) affecting kidneys, liver, brain & other organs. - Resembles GVH( Graft Versus Host Reaction , but etiopathogenesis is poorly understood. - Delivery is the only definitive treatment for pre-eclampsia and eclampsia. Pathogenesis of Toxemia of pregnancy: Unclear; - The primary cause may be immune or genetic factors → mechanical or functional obstruction of the uterine spiral arterioles → placental ischemia → endothelial injury & activation of disseminated intravascular coagulation, leading to decrease in glomerular filtrate, CNS disturbances, abnormal liver functions, and fibrin thrombi and ischemia in most organs.
    139. 139. THEORIES OT TOXEMIA OF PREGNANCY: 1- Inadequate placental implantation → decrease in uteroplacental perfusion and placental ischemia → increase production of vasoconstrictors (e.g. thromboxane , angiotensin) & decrease of vadodilators(e.g. prostaglandin I2, prostaglandin E2) → arteriolar vasocontriction & hypertension. 2- Recently ; Factors imbalance → premature termination of placental vascular growth. There is abnormal increase in an anti-angiogenic factor (sflt-1) and reduction in pro-angiogenic factors (Vascular endothelial-derived growth factor= VEGF & placental growth factor =PLGF ).
    140. 140. GESTATIONAL TROPHOBLASTIC DISEASES 1- HYADATIDIFORM (VESICULAR) MOLE: defined by- 1- Enlarged edematous and hydropic change of chorionic villi which become vesicular(Cystic swelling). Gross -Grape like 2-Variable trophoblastic proliferation. Two types: - Complete (diploid) & - Partial/Incomplete (triploid). - 10% develop into invasive mole, and 2.5% develop into choriocarcinoma. 2- INVASIVE MOLE: - Penetrates the uterine wall, produce hemorrhage but does not metastasize. - Responds well to chemotherapy.
    141. 141. Feature Complete mole Partial mole -Karyotype -Diploid (46 xxor 46xy), two sperms -Triploid(69 ). Two sperms fertilize an egg fertilize an empty egg. All genetic with normal chromosomes material is paternal -Rarely seen or absent - Fetal parts - Usually present with abnormalities - All villi - Some villi - Villous edema - Diffuse & circumferential - Focal and slight - Trophoblastic proliferation - Atypia -Often present -Abscent -Serum hCG - Elevated - less elevated -hCG in tissue - ++++ - + - Behavior - 2% choriocarcinoma - Rare choriocarcinoma
    142. 142. 3- Choriocarcinoma: - 50% follow hydatidiform mole & 25% follow normal pregnancy, 20% follow abortion & 5% follow ectopic pregnancy. - Highly malignant & metastasize widely. -Gross: Large, soft, yellowish white & fleshy with areas of hemorrhage and necrosis. -Histology: Abnormal proliferation of both cytotrophoblasts & cyncytiotrophoblasts invading the endometrium, blood vessels, lymphatics, no chorionc villi are seen. - Spread: To lung, bone marrow, liver & other organs.
    143. 143. Clinical features: Vaginal bleeding & discharge in the course of apparently normal prgnancy, after miscarriage, or high hCG titers. N.B.: All gestational trophoblastic disorders are associated with high level of hCG (tumor marker).
    144. 144. 4- Placental site trophoblastic Tumor: - A rare tumor composed of proliferating intermediate trophoblasts (larger than cytotrophoblasts but mononuclear than cyncytial). - D.D. from choriocarcinoma by the absence of cytotrophoblastic elements and low level of hCG production. - Mostly are locally invasive only, but malignant variants are distinguished by: - A high mitotic index, - Extensive necrosis, and - local spread. - About 10% result in metastases and death.

    Editor's Notes

  • Each month the uterus goes through a cyclical change, first building up its endometrium or inner lining to receive a fertilized egg, then, if conception does not occur, shedding the unused tissue through the vagina in the monthly process called menstruation
