Intramuscular hemangiomas are uncommon tumors of the head and neck, consistituting of 0.8% of all hemangioma, but often occur in the trunk and extremities. In the head and neck area, the masseter and trapezius muscle occur frequently, in which diagnosis is often difficult even with accurate preoperative imaging. The definitive diagnosis is made by histological study of the surgical biopsy specimen. Treatment of choice is complete surgical excision. This is, to our knowledge, the first case of intramuscular hemangioma of the mentalis muscle to be reported in korea.
