Endometriosis of Abdominal Wall Scarring

Endometriosis of the wall is a very rare pathology. Its pathophysiology remains unclear. It occurs on scars from gynaecological or obstetrical surgery. We report the case of a patient presenting a cyclic pain, at the level of the caesarean section scar, at the clinical examination a mass of 7cmx5cm localized at the level of the scar of the eventration cure. Pelvic computed tomography (CT) scan established the presence of a hypodense formation, measuring 75/55 mm extended over 40 mm, which rises in its periphery after injection of contrast agent, opposite the operative scar of the eventration cure at the expense of the skin tissue. The treatment was surgical with complete removal of the lesion and a pathological study was performed which confirmed parietal endometriosis. The postoperative follow-up was simple. Through our case, we draw the practitioners' attention to the great interest of evoking the diagnosis of parietal endometriosis each time a patient presents a mass of the wall with cyclic pain, in the close or distant aftermath of gynaecological surgery. This should systematically lead to a wide excision, followed by parietal reconstruction using prosthetic reinforcement if necessary, because of the risk of cancerization, the prognosis for which is considered to be poor.
