To report a case of intramuscular haemangioma (IMH) with a rare presentation in the mylohyoid, with emphasis on the clinical appearance, and histologic characteristics of the lesion.
Case report and review of the literature.
Neck swellings can often present a diagnostic dilemma, with a wide preoperative differential diagnosis. IMH are rare benign haemangiomas occurring within the skeletal muscle. They account for approximately 1% of all haemangiomas. These are uncommon in the head and neck region and occur most frequently in the trunk and extremities. In the head and neck, masseter and trapezius are the most common sites involved. Intramuscular haemangioma is seldom diagnosed preoperatively, perhaps due to unfamiliarity with this uncommon lesion and nonspecific clinical findings.
