Uterine tumor resembling ovarian sex cord tumor (UTROSCT) is a rare indolent stromal neoplasm of unclear histogenesis with a distinct histopathological entity. Immunophenotypes of sex cord positivity are the most significant information to confirm the diagnosis. We present the case of a 61-year-old female with a polypoid mass in the uterus which was successfully removed by surgical resection as hysterectomy. The pathological diagnosis was UTROSCT, which was characterized microscopically by sex cord images and immunohistochemical features of calretinin, CD99, and WT1 positivity.

子宫肿瘤样卵巢性索肿瘤（UTROSCT）是一种罕见的生长缓慢的间质性肿瘤，组织发生不明，具有独特的组织病理学特征。性索阳性的免疫表型是确诊的最重要信息。我们报告一例61岁女性，其子宫内有一个息肉样肿物，通过子宫切除术成功切除。病理诊断为UTROSCT，显微镜下其特征为性索样图像以及钙视网膜蛋白、CD99和WT1阳性的免疫组化特征。
