静脈石を伴った勃起性咬筋血管腫の1例

抄録

This case report describes an erectile hemangioma of the masseter muscle. The patient was a 21-year-old male with a 10-year history of illness who experienced bulging of his right cheek when he chewed. Because a hemangioma of the masseter muscle was suspected on the basis of a MRI study, resection was performed from within the oral cavity. The histopathological diagnosis was a cavernous hemangioma containing 3 phlebolith within the tumor mass. At the present, 3 years postoperatively, there are no signs of recurrence.
