[Parital cutaneous necrosis of the abdominal wall after cesarean section].

The authors report an original case of large cutaneous necrosis of the abdominal wall following a first cesarean section in a patient with a background of pemphigoid gestationis. There was no direct skin burn nor infection of the dermis and this necrosis is typical of venous suffering. The mechanism is debated, probably the thrombosis of the superficial inferior epigastric vein due to the spreading out of a monopolar coagulation current. A one-step treatment was done using a wide excision and an abdominal advancement flap. This surgical technique allowed a fast cicatrisation and led to a very good long-term esthetical result.
