Laparoscopic management of an ovarian steroid cell tumor, not otherwise specified causing virilization and amenorrhea: A case report

Abstract

Steroid cell tumors account for less than 0.1% of all ovarian tumors. There are three steroid cell tumor subtypes: steroid cell tumor not otherwise specified (NOS), stromal luteoma and Leydig cell tumor. Steroid cell tumor, NOS, is the most common type and has malignant potential. We report the case of 39-year-old woman complaining of pelvic pain and amenorrhea. Physical examination revealed hirsutism. Transvaginal ultrasound showed an hyperechogenic homogenous cyst of 4 centimeters of the left ovary without signs of malignancy. The right adnexa was normal. MRI imaging showed a left ovarian mass of 34 mm × 30 mm with enhancement after intravenous gadolinium. A left salpingo-oophorectomy was carried out with peritoneal cytology by laparoscopy. Histology concluded to a steroid cell tumor not otherwise specified, which had a low malignant potential. After 2 months, we noticed the regression of hirsutism and the patient had normal menses. She’s currently pregnant at 6 months of gestation. A complete surgical staging will be achieved after childbearing.
