Primary polycystic ovary syndrome in a premenarchal girl. A case report

A 12-year-old, premenarchal girl with hirsutism and virilization of nine months' duration was found to have highly elevated serum testosterone and a radiologic evaluation suggestive of bilaterally enlarged ovaries with a solid left ovarian mass. Serum gonadotropins were normal, with an LH:FSH ratio of 2:1. Exploratory laparotomy showed bilaterally enlarged polycystic ovaries, confirmed by wedge biopsies. No ovarian tumor was found. Oral contraceptives decreased the total serum testosterone to the normal female levels within three months. This was one of the youngest reported patients with primary polycystic ovary syndrome.
