Arrhenoblastoma is most common type (see ovarian tumors)
Hyperthecosis (of the ovary)
probably represents severe form PCOS / try meds, but oophorectomy may be necessary
Adrenal tumors
adenomas or carcinomas may produce excess androgens (+ or – cortisol)
Diagnosis: high levels of adrenal androgens (urinary 17-ketosteroids, serum DHEA) that cannot be suppressed by dexamethasone suggest

microinvasive SCC refers to <3 mm invasion, no blood vessels, no mets
invasive SCC is the most common cervical cancer / may be fungating, ulcerating, infiltrative
