Q

What is the underlying cause of PCOS?

A

Increased LH causes increased production of androgens, which is converted into estrone in adipose tissue. Estrone feeds back to decrease production of FSH. Decreased FSH leads to degeneration of the follicle, causing it to become a cyst.

Q

What happens to estrogen levels in PCOS?

They increase due to increased testosterone production (secondary to increased LH), which is aromatized in adipose to estrone. Estrone feeds back to inhibit FSH release, which causes degeneration of follicles and formation of cysts.

Yolk sac tumor - most common in kids. Schiller-Duval bodies (primitive glomeruli). AFP is marker.

Choriocarcinoma- tumor of trophoblastic tissue with no villi. Very aggressive, spreads hematogenously, poor response to chemo if spontaneous mutation. Responds well if it is a result of pregnancy B-HCG is marker.

Teratoma- tumor made of 2 or 3 layers of epithelium. Can contain thyroid tissue (struma ovarii). Usually benign.
