Congenital infantile fibrosarcoma: A masquerader of ulcerated hemangioma

Congenital infantile fibrosarcoma, a rare malignant tumor of childhood, may present as a highly vascularized mass that is clinically difficult to distinguish from a hemangioma. When ulcerated, significant hemorrhage, anemia, and thrombocytopenia may occur in children with these lesions. This report describes three infants with ulcerated congenital infantile fibrosarcomas of the hand. As appropriate medical and surgical management hinges on timely and appropriate diagnosis, we review the clinical manifestations of these lesions.
