title: Ovarian leiomyoma with hilus cell hyperplasia that caused virilization.
abstract: A 68-year-old woman had noted gradual virilization and depression for 3 years. Examination revealed a 10-cm right pelvic mass. Plasma testosterone was substantially elevated (1,082 ng/dl), but urinary ketosteroid and ketogenic steroid excretion was normal. Laparotomy revealed a 10-cm mass that replaced the right ovary and weighed 210 g. Histologic analysis revealed a leiomyoma and proliferation of hilus cells in the periphery of the mass. The plasma testosterone decreased postoperatively to 45 ng/dl. We believe that this is the first report of an ovarian leiomyoma associated with hilus cell hyperplasia that caused virilization.
