Intramuscular Hemangioma of Masseter; A Case Report

Abstract

In a 10-year-old girl, computed tomography showed a lobulated encapsulated mass in the masseter muscle. The mandible was greatly deformed by the tumor. Although benign tumor of the masseter muscle was suspected, we could not rule out malignancy. Histological examination of frozen sections revealed hemangioma. The tumor was removed totally without complications. In this patient, the extraoral approach, which provides wide exposure and facilitates total removal of the tumor, seemed more suitable than the intraoral approach. The characteristics, clinical features and treatment of intramuscular hemangioma are discussed.
