title: Intramuscular cavernous hemangioma of the masseter muscle.
abstract: Intramuscular hemangioma is relatively uncommon and frequently misdiagnosed, and even rarer in the head and neck region. The masseter muscle is the most frequent site for such hemangioma in the head and neck. A retrospective chart-review of intramuscular hemangioma in Keelung Chang Gung Memorial Hospital from 1983 through 1992 revealed the incidence of masseter muscle hemangioma is approximately 8% of all intramuscular hemangioma. Because of the rarity of these tumors, their vague presentations, inaccurate preoperative diagnosis and inappropriate surgical planning are common problems. This paper described five hemangiomas involving the masseter muscle with a review of the current literature on masseter muscle hemangioma.
