theories of endometriosus pathogenesis
regurgitation theory: retrograde menses thru fallopian tubes, endometrim into peritneum; metaplasia; lymphovascular dissemination
Endometriosis gross appearance
responsive to physiologic hormonal cycle. undergo periodic bleeding, producing dark nodules (gun powder appearance). lesions produce cystic masses filled with hemorrhagic material (chocolate cysts) and organization results in adhesions

polycystic ovary disease clinical features
3-6% women of reproductive age. bilateral ovarian enlargement from multiple follicle cysts. oligomenorrhea, w/ persistent anovulation, obesity, hirsutism, virilism (rarely)
pathogenesis polycystic ovary disease
increased LH, stimulates theca-lutein cells to produce androstenedione, converted to estrogen and testosterone; associated insulin resistence, hyperprolactinemia
histo of polycystic ovary disease
enlarged ovaries, numerous cystic follicles; fibrous thickening of cortex; hyperplasia of follicular theca cells; variable absence of corpora lutea; ENDOMETRIAL HYPERPLASIA AND CARCINOMA OCCUR IN A SIGNIFICANT PROPORTION OF PATIENTS DUE TO UNOPPOSED ESTROGEN PRODUCTION ASSOCIATED WITH ANOVULATORY CYCLES
Ovarian tumors epidemiology
80 % benign; benign in women under fifty; malignant in postmenopausal women
clinical presentation ovarian tumor
mild symptoms until large; symptoms and signs include abdominal pain, increasing abdominal girth; ascites; urinary and gastrointestinal tract disturbances; vaginal bleeding; rare hormonal activity
Classification of ovarian tumors
surface epithelial tumors; sex cord stromal tumors; germ cell tumors
surface epithelium of ovary embryological origin
embryologically derived from coelomic epithelium; embryonic coelomic epithelium gives rise to muellerian epithelium which differentiates into fallopian tube endometrial or endocervical
sex cord – stromal cells
embryonic precursors of the ovarian endocrine apparatus (theca and granulose cells)
germ cells embryonic origins
oocytes, which migrate from yolk sac, totipotential
epithelial ovarian tumor affected age group
over 20 yrs
germ cell ovarian tumor age group
0 to 25
sex cord ovarian tumor age group
all ages, often middle age or elderly
metastasis to the ovary age group affected
variable; tendency for older adults
histologic subtypes of epithelial ovarian tumor
serous; mucinous, GI type, endocervical type; endometrioid; clear cell; transitional (Brenner
histo subtypes of germ cell ovarian tumor
teratoma, mature, immature; dysgerminoma; yolk sac; choriocarcinoma
histo subtypes of sex cord ovarian tumor
granulose cell tumor; fibroma/fibrothecoma; sertoli-leydig cell tumor
most common primary sties of metasteses to ovary
opposite ovary; endometrium; colon; pancreas; stomach; breast
90% of malignant ovarian tumors what cell type?
ovarian surface epithelial tumors, embryology, differentiation
ovarian surface epithelium, coelomic mesothelium, differentiation towareds mullerian types of epithelium
differentiation subclassification of ovarian surface epithelial tumors
by type of epithelial differentiation: serous (like fallopian tube); mucinous (like endocervical or gastrointestinal); endometroid (like proliferative endometrial glands); clear cell (has glycogen making it clear looking); transitional; squamous; mixed; undifferentiated
architecture subclassification of ovarian surface epithelial tumor
cystic (cystadenoma or cystadenocarcinoma); cystic and fibrous (cystadenofibroma); predominately fibrous, minimal cyst formation (adenofibroma)
clinical behaviour subclassifications of ovarian surface epithelial tumor
benign (minimal epithelial proliferation and no stromal invasion); borderline (pronounced proliferation without stromal invasion); malignant (stromal invasion)
serous epithelial ovarian tumors appearance
benign are unilocular, with clear fluid and smooth internal lining; malignant are complex with papillary and solid areas, stromal invasion and necrosis; bornderline have complex epithelial growth with surface papillations, no stromal invasion
mucinous tumors of oivarian epithelium subtypes
endocervical (mullerian) features similar to serous tumors, high incidence of bilaterality, assoc with endometriosis/endosalpingiosis ; and gastrointestinal (resembling lining of stomach or bowel, may be assoc with pseudomyxoma peritonei (mucinous ascites w. implants on peritoneal surfaces) perhaps from GI source
