Hypothyroidism and hyperlipidemia with a virilizing ovarian steroid cell tumor, not otherwise specified.

Steroid cell tumors, not otherwise specified, are rare ovarian sex cord-stromal tumors with malignant potential. The majority of these tumors produce steroids, with testosterone being the most common. A 44-year-old woman with hypothyroidism and hyperlipidemia presented with abrupt onset of oligomenorrhea, progressive virilization as acne, hirsutism and clitoromegaly, and a non-palpable pelvic mass. The preoperatively elevated serum testosterone level returned to normal after salpingo-oophorectomy, and then menstrual flow became regular.
