Intramuscular haemangioma of the masseter muscle: a case report

Intramuscular haemangioma is relatively rare and accounts for less than 1% of all haemangioma. Most of these tumours occur in the trunk, arms and legs. Only 14% of all intramuscular haemangioma arise from the head and neck region, with masseter muscle representing the most common site of involvement, followed by the trapezius and sternocleidomastoid muscles. We present a case of a 60-year-old man with a soft lump in the left cheek. Imaging of the neck showed irregular, dilated enhancing vessels seen in the left masseter muscle suggestive of intramuscular haemangioma. Excisional biopsy was performed, and histopathological findings confirmed the diagnosis.
