Uterine tumors resembling ovarian sex cord tumors. A case report

Abstract

Uterine tumors resembling ovarian sex cord tumors (UTROSCT) are rare, usually benign, polypoid or nodular neoplasms which generally arise in the fourth to sixth decade of life. We report a case of a 74-year-old woman who presented with vaginal bleeding and remarkable uterine enlargement. Abdominal hysterectomy with bilateral salpingo-oophorectomy was performed and a diagnosis of UTROSCT was made. Immunohistochemistry is mandatory for a correct diagnosis and a panel of at least two markers of sex cord differentiation is recommended. Differential diagnoses include leiomyosarcoma, UTROSCT and ESTSCLE, mixed müllerian tumor and metastatic ovarian sex cord tumor.
