L36- Ovarian Pathology I Flashcards
list the types of ovarian lesions
Cysts: cystic follicle, follicular cyst, luteal cyst, chocolate cyst, PCOD
Tumors:
- metastasis (colon, GI, breast), 5%
- primary ovarian tumors: surface epithelium (90%), germ cell (3-5%), sex cord stromal (2-3%)
list the types of ovarian cysts
Non-Neoplastic:
-follicular, corpus luteum, chocolate, PCOD
Neoplastic:
- serous cystadenoma / carcinoma
- mucinous cystadenoma / carcinoma
- dermoid cyst
Follicular Cysts:
- stem from (1)
- (2) size
- (3) clinical features
- (4) Dx
1- unruptured follicle OR ruptured follicle that is immediately sealed off
2- 2cm, up to 4-5 cm
3- silent, pain, endometrial hyperplasia
4- US
Chocolate Cysts:
- stem from (1)
- chocolate color results from (2), which also induces (3) processes
- (4) appearance
1- endometriosis (endometrial tissue in ovary)
2- repeated cyclical hemorrhage
3- fibrosis, adhesions, pain
4- normal endometrial glands + stroma + RBC + hemosiderin
Chocolate Cysts:
- mainly needs to be distinguished from (1)
- may grow / extend with (2)
- associated with (3) as a symptom or complication
1- corpus luteum cysts
2- pelvic ligaments
3- infertility
PCOD, aka (1):
- (2) most commonly affected women
- (3) main Sxs
1- Stein Leventhal Syndrome
2- young, post-menarche, those with persistent anovulation
3- oligomenorrhea, secondary amenorrhea, hirsutism, obesity (40%), infertility
PCOD: describe hormonal changes and why
- inc androgen => 50% hirsutism, rarely virulization (poorly regulated enzymes)
- inc LH // dec FSH
- insulin resistance
PCOD causes increase in circulating androgens:
- (1) is the main fate of androgens
- (2) and (3) are the hormonal effects of (1)
- (4) is the connection to repeat this cycle
1- androgens –> (adipose) –> estrogens
2- inhibits FSH release
3- stimulates GnRH release –> inc LH release (but not FSH)
4- LH stimulates theca cell androgen production
PCOD, describe the direct or symptomatic effects of:
- (1) excess estrogen
- (2) excess androgen
1- endometrial hyperplasia, stimulates adipose cells in body –> obesity
2- hirsutism, virilization + processed thru adipose / liver –> excess estrogens
PCOD ovarian changes
- 2x larger
- subcortical cysts, 0.5-1.5 cm
- large, thick capsule, multiple unruptured follicles as cysts lined by granulosa cells and hypertrophied theca interna cells
- thick hypertrophied stroma
PCOD Dx
- hormonal assay
- transvaginal US
PCOD Tx
-depends on age and Sxs
Hormonal: break cycle; clomiphene induces ovulation if fertility is desired
Previously: wedge resection of ovary to help ovulation to reduce mass
Sxs:
- hirsutism - spironolacone
- DM - metformin
- obesity - weight loss
list the many clinical features of ovarian disease
-clinically silent for long time –> lots of space to grow
Mass Effects (mostly): pressure, swelling, ascites –> abdominal pain / enlargement, pelvic discomfort, frequent micturation, GI issues
Hormonal Effects (rare): endometrium (menstrual irregularities), breast enlargment, hirsutism
- infertility (no ovulation)
- Advanced CA: cachexia, weight loss, weakness
list the ovarian tumor investigations
- abdominal palpation
- US, CT scan
- FNAC via pouch of douglas
- ascitic fluid tap
- mass biopsy (uncommon)
- CA125 levels in serum
- hormone estimation
CA125 is described as (1) and is mainly used for (2). (3) is a main caveat to its use. (4) is its main value clinically.
1- high MW glycoprotein
2- tumor marker –> endometrial CA
3- inc in a variety of non-specific conditions that irritate peritoneum + tumors limited to ovary are 50% negative
4- possible use as screening in asymptomatic post-menopausal women, BUT mainly for monitoring response to therapy / disease progression
