[Endometriosis of the lower abdominal wall. Report of two cases secondary to cesarean section]

The paper describes two cases of cutaneous endometriosis in correspondence with the surgical scar following cesarean section. The cases formed part of a series of 500 abdominal operations performed during the period 1988-89, of which about 200 were cesarean sections, with a 1% frequency. In line with the hypothesis regarding the spread of endometrial tissue during surgery and with that concerning peritoneal metaplasia, the authors recommend paying special attention during the technical procedure of extracting the fetus, and performing an introflexed suture of the uterine incision and of the parietal peritoneum.
