Bilateral androblastoma (Sertoli-stromal cell tumor) of the ovary: a rare cause of virilization in a teenager.

A case of a 17-year-old patient diagnosed with bilateral androblastoma of the ovary is presented. The patient was admitted because of secondary amenorrhea, hirsutism and acne. After clinical, ultrasonographic and hormonal examinations an androgen-producing ovarian tumor was suspected and consequently laparotomy with right ovarian tumor excision and left ovary exploration was carried out. During surgery the right ovarian tumor was excised and exploration of the left ovary revealed an ovarian tumor with a diameter of 10 mm, which was then also excised. The pathologic diagnosis was a bilateral androblastoma of the ovary measuring 40 mm x 30 mm x 20 mm in the right ovary and 10 mm in diameter in the left ovary. We concluded that androblastomas, in spite of their low incidence, are a possibility that should always be considered in women of all ages presenting with signs of virilization.
