Congenital skin loss following Nd:YAG placental photocoagulation.

This is the first reported case of congenital skin loss following endoscopic placental laser coagulation, a new technique for the ante-natal treatment of twin-twin transfusion syndrome. The skin defect healed rapidly after birth with dressings alone, mimicking the spontaneous re-epithelialisation of a minor burn wound or aplasia cutis congenita.
