Benign neonatal eruptive hemangiomatosis in identical twins.

Two cases of neonatal hemangiomatosis occurred in identical twins. Work-up for internal hemangiomas were performed on both infants and were negative. Twin no. 1, with extensive lesions, is currently taking oral prednisone, 2 mg/kg/day, with gradual resolution of the lesions. So far, no new hemangiomas have developed in twin no. 2.
