Abstract

Virilizing ovarian tumors are rare but a clinically important diagnosis in a patient presenting with hyperandrogenism. Workup of hyperandrogenism is challenging with a broad range of differentials, including adrenal and ovarian pathology, tumoral or nontumoral in nature. Baseline follicular-phase 17-hydroxyprogesterone (17OHP) measurement is part of the investigation algorithm, and elevated levels are often associated with nonclassic congenital adrenal hyperplasia (NCCAH), which can have its first presentation in adolescence or adulthood. This case describes a young adult woman of reproductive age presenting with menstrual irregularity, raised testosterone, and 17OHP. After extensive workup and serial follow-up, she was found to have a Sertoli-Leydig cell tumor of the left ovary and underwent successful laparoscopic salpingo-oophorectomy with normalization of her menstrual irregularity and biochemical resolution of her testosterone and 17OHP levels.
