Abstract: Broad ligament leiomyosarcoma is a rare and aggressive soft tissue sarcoma. It is more commonly seen in postmenopausal women. Diagnosis can be difficult preoperatively and often it is confused with adnexal tumors. We herein report a case which was diagnosed as ovarian carcinoma by imaging studies but intraoperative findings and histopathology concluded it to be a broad ligament leiomyosarcoma.
