12. 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

- Sporadic endometrial breakdown & bleeding ( estrogen effect
unopposed by progesterone).
14. 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 - : Chancre - 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.
17. 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)
18. Lymphogranuloma 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
19. 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.
20. Infection involving the lower and the
upper genital tract
(Pelvic inflammatory disease =PID)
Definition: an ascending infection that
begins in the vulva & spreads upward
to involve the entire genital tract.
21. 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.
22. 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.
24. 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).
25. Papillary Hidradenoma: benign, well
circumscribed nodule of modified apocrine
sweat gland. It is composed of tubular
structures lined by both epithelial(columner) &
myoepithelial cells.
26. 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).
-
27.
28. Differentiate (simplex) VINs
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.
29. 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
30. Verrucous Carcinoma: A rare locally aggressive
neoplasm. Usually does not metastasize.
,
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
32. 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 )
34. 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.
35. 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
37. 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
38.
39. DISEASES OF THE CERVIX
Inflammation of Cervix: Cervicitis
Cervical Tumors
40. 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
41. 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.
42. 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
47. 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)
48. - 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.
49. Morphology:
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)

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. 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.
53.
54. 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).

57. DISEASES OF THE ENDOMETRIUM
ENDOMETRITIS:
ADENOMYOSIS & ENDOMETRIOSIS:
ENDOMETRIAL HYPERPLASIA
TUMORS OF THE ENDOMETRIUM
58. 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.
59. 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.
- Criteria 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 ).
65. 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.
71. 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.
72. 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
73. 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.
76. 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.
77. 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..
-
78. 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.
79. 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
80. - 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

85. 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.
86. - 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%.
87. Benign tumors
Leiomyoma
Malignant tumors
Leiomyosarcoma
TUMORS OF THE MYOMETRIUM
88. 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).
89. 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).

92. 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%
93. Histologically distinguished

DISEASES OF THE FALLOPIAN TUBES
99. 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
103. - 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.

108. 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.
109. 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).
OVARIAN DISEASES
110. INFLAMMATORY - OOPHORITIS:
- Inflammation of the ovaries is always secondary to
salpingitis or peritonitis.
- If chronic & bilateral leading to extensive fibrosis &
infertility.
111. 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.
112. NON-NEOPLASTIC OVARIAN CYSTS
3 – Polycystic Ovarian Cystic Disease ( 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.
120. 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.

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.
139. MUCINOUS TUMORS
Large cystic masses, huge size, and multiloculated. Cysts filled with sticky
gelatinous fluid. They either lined by tall columnar mucus-secreting
epithelium (intestinal-type mucinous cystomas) or show papillary

structures. 10-15% are bilateral. < 1% undergo malignant
transformation (MC sq.c.c.).
2-Immature (Malignant) Teratoma: Rare , solid, bulky, with areas of
hemorrhage and necrosis. It contains embryonic elements of he three
germ layers. Age: adolescent & young women. Grading is based on the
amount of immature neuroepithelium. It causes wide spread
extraovarian metatases depending on the degree of the immaturity of
the including tissues.

but is radio- & chemosensitive.
- Histologically: it shows cystic spaces into which papillary
structures with central blood vessels , the cyst spaces and
papillary structures are lined by immature epithelium
giving glomeruloid or “Schiller-Duval” bodies; There are
intracellular and extracellular hyaline droplet
(characteristic feature). Tumor cells are positive for Alpha-
fetoprotein (tumor marker).
167. - It is due to teratogenous development of germ cells.
- Most cases exist in combination with other germ cell
tumors.
- Resembles gestational choriocarcinoma, highly
malignant, spreads widely & elaborates hCG (tumor
marker).
- Microscopic picture: malignat syncitiotrophoblasts

Krukenberg tumor
187. 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.
188. 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.
189.
190.
191.
192.
193.
194. 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.
195. 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.
196. 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 ).
197. 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.

- 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.
207. 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).
208.
209.
210.
211.
212. 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.
214. Contraception
Contraception is the prevention of conception by methods
other than abstinence , its used to limit the size of family
( birth control )
or
( Family planning)
215. Ideal Contraception
An ideal contraception should fulfill the following:
Highly efficient
Free from unwanted side effect
Absolute safety
Simplicity of use
Reversible
Well tolerated
217. FEMALE CONTRACEPTION
Intra Uterine Devices
Inert

220. SIDE-EFFECTS
Minor side-effects commonly occure during the 1st
3 cycles & may lead to unnecessary
discontinuation
1. Irregular bleeding (breakthrough bleeding/ spotting)
10-30% in the 1st month of use
improves with time over 3 cycles
amenorrhea 2-3% of the cycles
2. Breast tenderness & nausea
Improve with time
Less with lower estrogen dosage
221. SIDE-EFFECTS
3-Wt gain
Placebo controlled trials have failed to show any
association between wt gain & COCP
4-Mood changes
Women report depression & mood changes
Placebo controlled trials have failed to show any
significantly increased risk of mood changes
with COCP
222. RISKS OF OCP
1-Venous thromboembolism
VTE 3-4 X higher in users than nonusers
Absolute risk of VTE in COCP users –
1-1.5/10 000/year
Risk of VTE is higher during the 1st year of use than
subsequent years
Incidence of VTE in nonpregnant women is 0.3/
10000/year at 20-24 Y------0.6 at 40-44 Y
Incidence of VTE in pregnancy is 13/ 10000 deliveries
The risk is attributed to the estrogen component of the
pill & decline with lower dosage
223. RISKS OF OCP
3-Stroke
Some studies showed 2X ↑↑ risk of stroke
Smoking & HPT ↑↑ risk of stroke
4-Gallbladder disease
COCP ↑↑ secretion of cholic acid in bile ↑↑ incidence of gallstone
formation
No significant ↑↑ risk of gallstone formation in COCP users
5-Breast cancer
Still controversial
A large meta-analysis 1996 significant ↑ risk of breast
ca in women currently taking the COCP( Relative Risk
1.24 ) & in the 1st 10 Y after discontinuing it
224. RISKS OF OCP
5-Breast cancer
Cumulative breast ca risk up to age 35 is 2 / 1000
with COCP --------------------------------------- 3 / 1000
It is not known whether this ↑ is due to the pills or due to delaying
the 1st full term birth
More recent study > 9000 women no significant ↑↑ in breast ca
risk
No ↑↑ risk with different dosage of estrogen, longer periods of use,
or with different progestin components
No ↑↑ risk in Pt with family Hx of breast ca
No ↑↑ risk in Pt who started using the pills at an earlier age
↑↑ risk in Pt who carry BRCA1, BRCA2 genes
225. RISKS OF OCP
6-Cervical cancer
One study ↑↑ risk of Cx ca in long term COCP users
who are HPV positive
A review of 28 studies of women with Cx ca ↑↑ risk of
Cx ca with ↑↑ duration of COCP use
Probably due to ↑↑ risk of HPV (a major risk factor for cx
ca) that might be related to sexual behavior which differs
in users & non users of COCP
Another study HPV + ve women follwed up for 10 years
showed no increased risk
226. IUCD MECHANISM OF
ACTION
Prevention of fertilization the chief mechanism
Inhibition of implantation
Presence of foreign body & copper biochemical &
morphological changes in the endometrium adversely affect
sperm transport
Copper ion have direct effect on sperm mobility ↓↓ in its
ability to penetrate Cx mucous
Levonorgestrel releasing devices weak foreign body reaction
& endometrial decidualization & glandular atrophy estrogen &
progestrone receptors are ↓↓ Cx mucous becomes thick &
impermeable to sperms ovulation may be inhibited in some
women
227. INDICATIONS FOR IUCD
In the absence of contraindications may be considered for any
woman seeking a reliable, reversible, coitally independent
method of contraception
Women seeking long term birth control
A method requiring less compliance
Women with contraindications to estrogen
