Abstract:

Objective To analyze the clinicopathological characteristics and differential diagnosis of ovarian sclerosing stromal tumor.Methods The clinicopathological characteristics of 10 cases of ovarian sclerosing  stromal tumor treated at our hospital were examined. Results Mean age of the patients was 48.7 years（17-78  years） and clinical symptoms were usually abdominal pain，shortened menstruation，postmenopausal bleeding and frequent micturition. Macroexamination revealed unilateral，glossy and coated tumors with a surface cap-sule. Optical microscopy of tumor tissue revealed a false lobular structure. All patients were positive for SMA，Vimentin，and α-inhibin. Conclusions Ovarian sclerosing stromal tumor is rare and clinical data about the disease are limited. Therefore diagnosis is difficult and usually relies on pathology and the efficacy of operation is good.
