Mature cystic teratoma originating in the broad ligament: a case report.

Teratomas are germ cell tumors, commonly affecting ovaries. Teratomas rarely affect extragonadal tissues. Few cases of teratomas occurring in extragonadal tissues have been reported in the past. However, no studies have reported cases of primary teratomas occurring in the broad ligament. In this study, we report a case of a sexually inactive young woman with a 3-day history of lower abdominal pain. B-ultrasound examination revealed an abnormal strong echogenicity mass in the left adnexal area. An exploratory laparotomy was performed on her. The surgery revealed normal size and appearance of both ovaries and uterus. However, a cyst was observed in the left broad ligament, which was diagnosed as benign mature teratoma based on pathology. In this study, we report a rare case of broad ligament teratoma. The clinical data enrich our understanding of teratomas and provide a reference for further studies.
