Abstract

Sertoli–Leydig cell tumor belongs to the group of sex cord–stromal tumors of the ovary. These neoplasms account for less than 0.5% of all ovarian tumors and are more often encountered in young women between the ages of 20 and 30 years who usually become virilized. We described an unusual case of Sertoli–Leydig cell tumor in a postmenopausal women who presented with a solid right pelvic mass, a large amount of ascites, and laboratory tests revealing an elevated CA125, all suggesting a pelvic malignancy. Although five similar cases of postmenopausal women with Sertoli–Leydig cell tumor of ovary have been reported in the literature, we believe that this is an useful addition to the literature.
