Lipid cell tumor of the ovary.

A 32-year-old nulligravida, with a history of abdominal hysterectomy for multiple leiomyomas of the uterus, was seen initially with signs of masculinization. Normal values for 17-ketosteroids, 17-hydroxycorticosteroids, and plasma cortisol eliminated the adrenal as the source of the excess androgen as well as Cushing syndrome. Increased plasma testosterone and androstenedione levels in the peripheral blood as well as in the right ovarian vein sampling implicated the right ovary, which revealed a lipid cell tumor (0.5 to 1.3 cm in maximum dimension).
