Abstract

Endometrial stromal sarcoma (ESS) is a relatively rare form of uterine sarcoma. ESS of the myometrium compose just 0.2% of uterine malignant tumors. Low-grade ESS has extended beyond the uterus in 40% of cases at the time of diagnosis. ESS of ovary is very rare. Most of ovarian ESS is concomitant with endometriosis or same tumor in uterus. We have experienced a primary ovarian low-grade ESS, and that sarcoma is localized in ovary. So, we report this case with review of literature.
