Uterus-Like ovarian mass with elevated serum levels of CA 19-9 and CA 125: a case report and review of the literature

Abstract

Uterus-like ovarian mass is a rare benign entity with controversial etiopathogenesis. A 37-year-old woman, gravida 2, para 2, presented with the complaint of pain in right lower abdominal quadrant. Physical evaluation revealed tenderness in this area and the ultrasonographic examination showed a right adnexial mass. Biochemical blood tests showed minimal leucocytosis and elevated serum levels of both CA 19-9: 117.79 mIU/mL (N: 0-37) and CA 125: 41.4 u/mL (N: 0-35). To exclude a malignancy, the specimen was examined with frozen sections and was subsequently diagnosed as endometriosis. Therefore, the surgical procedure was limited to right salpingo-oop- horectomy. The right ovary was 6 × 4 × 2.5 cm in size and the dissected surface of ovary resembled a miniature uterus. Histologic sections as well as immunohistochemistry (smooth muscle actin, caldesmon and CD10) were consistent with the endometrial mucosal tissue that surrounded the bundles of smooth muscle. © 2010 by Türkiye Klinikleri.
