1) The breast has lobes containing lobules made of acini (alveoli) connected by ducts. Lymphatic drainage is mostly to axillary lymph nodes.
2) There are three normal phases: active, lactating, and atrophic based on gland to stroma ratio.
3) Breast pathology includes developmental disorders, degeneration, inflammation, and neoplasms. Common neoplasms are benign epithelial tumors like fibrocystic changes, proliferative lesions, and in situ or invasive carcinomas.
4) Prognostic factors for breast cancer include stage, age, biomarkers like hormone receptors, and histologic grade.
Ovarian Cyst Causes
Ovarian Cyst Miracle Program ►►► http://betterhealthchannel.net/OvarianCystMiracleTreatment
Are you struggling to get rid of your ovarian cysts? Are you in pain, or feeling anxious for not being able to properly cure your ovarian cysts despite all your efforts ? Are you experiencing irregular periods, pain in your lower abdomen or bloating? Are you afraid of developing cancer or from not being able to have children? If you answered yes, then you have come to the Right place for a solution!
Most ovarian cysts develop as a result of the normal function of your menstrual cycle. These are known as functional cysts. Other types of cysts are much less common.
Your ovaries normally grow cyst-like structures called follicles each month. Follicles produce the hormones estrogen and progesterone and release an egg when you ovulate. Sometimes a normal monthly follicle keeps growing. When that happens, it is known as a functional cyst. There are two types of functional cysts:
Follicular cyst. Around the midpoint of your menstrual cycle, an egg bursts out of its follicle and travels down the fallopian tube in search of sperm and fertilization. A follicular cyst begins when something goes wrong and the follicle doesn't rupture or release its egg. Instead it grows and turns into a cyst.
Corpus luteum cyst. When a follicle releases its egg, the ruptured follicle begins producing large quantities of estrogen and progesterone for conception. This follicle is now called the corpus luteum. Sometimes, however, the escape opening of the egg seals off and fluid accumulates inside the follicle, causing the corpus luteum to expand into a cyst.
The fertility drug clomiphene (Clomid, Serophene), which is used to induce ovulation, increases the risk of a corpus luteum cyst developing after ovulation. These cysts don't prevent or threaten a resulting pregnancy.
Functional cysts are usually harmless, rarely cause pain, and often disappear on their own within two or three menstrual cycles.
Other cysts
Some types of cysts are not related to the normal function of your menstrual cycle. These cysts include:
Dermoid cysts. These cysts may contain tissue, such as hair, skin or teeth, because they form from cells that produce human eggs. They are rarely cancerous.
Cystadenomas. These cysts develop from ovarian tissue and may be filled with a watery liquid or a mucous material.
Endometriomas. These cysts develop as a result of endometriosis, a condition in which uterine endometrial cells grow outside your uterus. Some of that tissue may attach to your ovary and form a growth.
Dermoid cysts and cystadenomas can become large, causing the ovary to move out of its usual position in the pelvis. This increases the chance of painful twisting of your ovary, called ovarian torsion.

Pelvic organ prolapse occurs when the muscles and tissues supporting the pelvic organs such as uterus, bladder, or rectum become weak or loose. This problem is usually found in women and they feel uncomfortable or sometimes feel pain also. But this problem is easily curable with time. At Healing Hands Clinic, Dr. Ashwin Porwal treats patients of pelvic organ prolapse with Pelvic Organ Prolapse Suspension Surgery advanced technique made popular by the world-renowned Colorectal surgeon, Dr. Antonio Longo ( Italy ). Dr. Porwal has mastered the technique from Dr. Longo himself and he was the first to perform this surgery in India.
Uterine malformations result from partial or complete failure of one of three mechanisms either separately or combined - agenesis, fusion, and resorption. Agenesis results in either a complete absence of the uterus or a unicornuate uterus; a failure to fusion gives rise to uterine didelphys or a bicornuate uterus; and a septated uterus is due to a failure of resorption.
Overview normal physiological development; skeletal growth, maturation of the reproductive tract, development secondary sexual characteristics, CNS maturation, personality and psychology of the female adolescent.

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

• LOBE: (10 in whole breast)
• LOBULE: (many per lobe)
• ACINUS/I, aka ALVEOLUS/I:
(many per lobule)
• DUCT(S): INTRA- or INTERLOB(UL)AR, leading to the
lactiferous ducts in the nipple
69. LCIS
• Usually hangs around MANY MANY
years before it infiltrates, in contrast to
DCIS
• The BEST management may be
judicious neglect, i.e., observation
• If it does infiltrate, however, it is at
least as bad as DCIS infiltrating, or
probably WORSE, showing “indian”

Confusion between lobe, lobule, acini, alveolus, and duct is rampant in clinical medicine, but should never be confusing for you.
Ther are an average of about 10 LOBES per breast. The suspensory ligament separates lobes.
A lobule is part of a lobe composed of many acini. Lobules are separated from each other by bands of connective tissue.
Acini are also known as alveoli.
Acini are composed of glandular cells and myoepithelial cells.
Active
Pregnancy/Lactation
Atrophic, i.e., post menopausal
Breast tissue that is ~90% glandular and/or looks like “thyoid”, i.e., filled with milk, are lactating breasts
Nipple lines extend from the axilla to the pubic regions, these are also called milklines.
Go home and see if you hav any “moles” on your milk lines, and if you do, they may be accessory nipples.
Breast tissue ALWAYS extends to the axilla, and when it does form an actual protuberance, it can be called an accessory breast. Breasts are modified apocrine sweat glands embryologically.
Nipple retraction can be congenital or acquired, when acquired, it represents suspicion for underlying fibrosis due to neoplasm or inflammation.
Macromastia.
Atrophy is a NORMAL feature of postmenopausal breasts (estrogen withdrawal).
Stroma>>>>>glands in atrophy, but lobules and acini are still present architecturally. Most carcinomas occur in atrophic (post menopausal,estrogen withdrawal) breasts
All 4 of the classical signs of inflammation, heat redness, swelling, pain. What the the fifth?
Intraductal and periductal inflammatory cells, mostly neutrophils in acute mastitis.
Pap smear of nipple exudate in acute mastitis. What are most of these cells?
Inflammatory carcinoma with its classic peau d’orange appearance.
Note the tiny little “pits” in the orange peel.
The tumor cells are INSIDE the skin dermal lymphatic spaces.
Most of the inflammation here is PERI- ductal rather than INTRA- ductal. Acute or chronic? Why? Ans: Lymphocytes.
Ductesia means dilated ducts.
Dilated ducts are the same as cysts.
“apocrine” refers both to a METHOD of SECRETION (as opposed to merocrine and holocrine), as well as a TYPE of CELL
Classic cheesy appearance of fat in fat necrosis. Fat necrosis is usually due to mechanical trauma, surgical or otherwise.
Giant cells and hemosiderin are usually easily found in fat necrosis. You should have no trouble finding either here.
What is the principal inflammatory cell here? Ans: Lymphocyte.
Because of this, would you like to call it “chronic” mastitis? Be my guest.
The appearance is 100% exemplary of the diagnosis.
All possibilities: Benign and malignant, glandular (i.e., epithelial) and stromal, and “borderline”.
“Fibrocystic disease” is the waste basket term for benign breast disease characterized by fibrosis, cysts, inflammation, and a host of other benign changes. Certain features such as hyperplasia and papillomatosis, put it in a somewhat higher risk category for future carcinoma.
Breast cyst, filled with fluid, in the pathology lab.
Breast cyst, filled with fluid, in the ultrasound lab.
This image speaks for itself. Do you think there is some apocrine metaplasia here too? Ans: YES
Adenosis is defined as an increased number of acini per lobule.
Hence the name, “fibrocystic” disease.
“Benign” hyperplasia is characterized by, NO necrosis, the presence of MYOEPITHELIAL cells, and NO ATYPIA.
Find a classical myoepithelial cell on the left.
Sclerosing adenosis is often confused with malignancy. Why? Ans: the “sclerosis” can be mistaken for desmoplasia.
VERy very very scary, but 100% benign, lesion.
Note the myoepithelial cell. The presence of myoepithelial cells, means, BENIGN!!!
Like meningiomas, fibroadenomas have the consistency of superballs, and you always feel like you want to bounce them!
Our old friend the papillopma, i.e., a fingerlike proliferation of epithelium, growing over a fibrovascular core.
Number 1 commandment in pathology: NEVER diagnosis a malignant papilloma on a frozen section!!!!! NEVER.
The asterisked items, are more suspicious than the non-asterisked items. Intraductal NECROSIS is the most suspicious feature of all.
Note the INTRADUCTAL NECROSIS.
Note the atypia, “swiss cheese” hyperplasia, and early necrosis.
Note the extreme artypia.
Microcalcifications, seen on mammograms, are often the result of necrotic intraductal crud which has calcified. Lets make this quite simple: NECROSIS in a hyperplastic duct is usually DCIS
This type of calcification represents about a 20% chance of malignancy and should be biopsied. This device helps pathologists to sample the areas of greatest concern more heavily.
The Romans built many nice bridges, but not in China.
A whole lobule filled with monotono0us cells of the same type can be called LCIS, or lobular carcinoma in situ. Note the COMPLETE LACK of atypia and necrosis, but it’s still CA-in-situ because this is a LOBULE!
A whole lobule filled with monotonous cells of the same type can be called LCIS, or lobular carcinoma in situ.
HER2 is a proto-oncogene located at the long arm of human chromosome 17(17q11.2-q12).
Approximately 25-30 percent of breast cancers have an amplification of the HER2/neu gene or overexpression of its protein product.
Overexpression of this receptor in breast cancer is associated with increased disease recurrence and worse prognosis.
Because of its prognostic role as well as its ability to predict response to trastuzumab,
breast tumors are routinely checked for overexpression of HER2/neu. Overexpression also occurs in other cancer such as ovarian cancer and stomach cancer.
90% of infiltrating breast carcinomas are simply called “Infiltrating Ductal Carcinoma” on the pathology report.
Indian file, British or American origin?
The “tubular” pattern is somewhat better in behavior.
The mucinous variant is also somewhat better in behavior.
The medullary variant (i.e., lots of immune calls or lymphocytes) is also somewhat better in behavior. If you want to think that the reason for this is because there are a lot of immune cells “fighting” the tumor cells, you might be right, but it also tends to occur in younger women, who have the advantage of a younger age.
Note that no matter how big a male’s breasts may get, they should never form lobules, but just end as blunt ducts.
