Massive hemorrhage: A rare complication of rapidly involuting congenital hemangioma.

Rapidly involuting congenital hemangioma is a subtype of congenital hemangioma. Ulceration and bleeding are rarely reported in rapidly involuting congenital hemangioma, with only four cases reported in the literature to our knowledge. We describe a case of a newborn girl who presented with rapidly involuting congenital hemangioma complicated by ulceration and severe bleeding and discuss treatment.
