The most common location is within the pelvis. However, extra pelvic endometriosis is a fairly uncommon disorder and difficult to diagnose. It can sometimes occur in a surgical scar. Scar endometriosis is a rare condition and difficult to diagnose. It mostly follows obstetrical and gynecological surgeries. It presents as a painful, slowly growing mass in or near a surgical scar. We report two cases of abdominal wall endometriosis following hysterotomy and cesarean section. Consequently the pathogenesis, diagnosis and treatment are discussed. https://jfrh.tums.ac.ir/index.php/jfrh/article/view/41 https://jfrh.tums.ac.ir/index.php/jfrh/article/download/41/41
