Subcutaneous and Fascial Abdominal Wall Endometriosis in the Setting of Previous Gynecologic Surgeries: Two Case Reports

Abdominal wall endometriosis is a rarely reported condition with increasing incidence linked to pelvic surgery, and is also referred to as incisional endometriosis. Here we report two cases of women with previous history of Cesarean section who presented with abdominal wall masses years after surgery. In both cases, CT imaging was used to visualize the masses and surgical exploration and tissue examination revealed the excised masses to be endometriosis of the abdominal wall. Etiology of this ectopic endometrial tissue may be iatrogenic and caused by implantation of endometrial tissue during operative proceedings. This paper aims to highlight the incidence of abdominal wall endometriosis and to discuss differential diagnoses and management.
