Abstract

Infantile congenital fibrosarcomas are rare neoplasms that usually present on the extremities, and although they are locally invasive, they rarely metastasize. They are commonly misdiagnosed as hemangiomas or other vascular tumors, so further evaluation by pathology is required for proper diagnosis. We describe a newborn with a neoplastic growth of the lower lip that was thought to be an infantile hemangioma that did not respond to therapy. When the child was 2 months old, an incisional biopsy demonstrated a fibrosarcoma. This case highlights congenital infantile fibrosarcoma as a mimic of infantile hemangioma. To our knowledge this is first case report of congenital infantile fibrosarcoma involving the lip.
