A 30-year-old woman presented with increased body and facial hair, deepening of the voice, acne and menstrual abnormalities. An ultrasound showed a unilateral solid right ovarian mass. At surgery, the left ovary, uterus and abdominal cavity appeared normal. A unilateral salpingo-oophorectomy was performed. On gross examination, the ovary contained a well circumscribed 6.0 cm solid yellow, somewhat lobulated, mass without surface involvement. Tumor cells were positive for inhibin and calretinin, but were negative for cytokeratin 7.
