leydig stromal cell tumor is a rare ovarian tumor that belongs to the group of sex-cord stromal tumors. they produce testosterone leading to hyperandrogenism. we present a 41yr old woman with symptoms of virilization and a mass of right adenex via ultra sonography, and a rise of total and free serum testosterone. an ovarian source of androgen was suspected and a surgery performed. a diagnosis o...
