Abdominal wall endometrioma after Cesarean section: a case series

Abdominal wall endometrioma (AWE) results from endometrial-like tissue implants in the abdominal wall after uterine surgery. While the diagnosis can be challenging, an abdominal mass at the site of a previous incision accompanied by cyclical pain and enlargement correlating with menstruation is highly suspicious. Excision is indicated for symptomatic relief as well as the probability of malignant transformation. Because signs and symptoms are similar to other soft tissue lesions, general surgeons are sought out for excision and thus encounter the majority of AWE cases. Here, we present two patients of similar age who both presented to our hospital within one month, each found to have an endometrioma at the site of a Pfannenstiel scar after Cesarean section, and were managed operatively.
