Adult invasive subcutaneous hemangioma

Hemangiomas consist of a spectrum of benign vascular tumors with variable clinical behavior and microscopic morphology, which usually occur in infancy. A rare variant of these tumors is the invasive subcutaneous hemangioma, which shows an aggressive growth pattern by invading subcutaneous structures and recurring after apparent excision. The authors describe an adult patient with a large submandibular invasive hemangioma who was treated by preoperative embolization and surgical excision.
