BILATERAL VIRILIZING HILUS (LEYDIG) CELL TUMORS OF THE OVARY

A 72-year-old postmenopausal woman with high plasma testosterone levels and virilization, as demonstrated by hirsutism and balding, is presented. Urinary 17-ketosteroids and 17-hydroxycorticosteroids, as well as computed axial tomography scan of the adrenal glands were normal. Although no pelvic mass was detected by ultrasonography or pelvis examination, the patient was found to have small bilateral hilus cell tumors of the ovary. Following bilateral salpingo-oophorectomy the plasma testosterone dropped to normal level. This is the third case of bilateral hilus cell tumors of the ovary to be reported.
