title: Sertoli-Leydig cell tumor of the ovary producing alpha-fetoprotein.
abstract: A 16-year-old girl with virilization and elevated serum alpha-fetoprotein (AFP) levels was found to have a Sertoli-Leydig cell tumor of the ovary. Immunoperoxidase studies using anti-AFP localized AFP in cells with the histologic appearance of Leydig cells. Serum AFP fell to undetectable levels after excision of the tumor. The patient is alive and well 1 year postexcision.
