A case of erectile cavernous hemangioma in the masseter muscle

Abstract

This report presents the detailed description of a case of erectile cavernous hemangioma in the masseter muscle.
A 15-year-old male patient was referred to our Department on February 28, 1986 with a chief complaint of a hemispherical swelling of the right masster region at masseter muscle contraction or physical exercise.
Clinical examination revealed that the swelling appeared immediately following masseter muscle contraction and disappeared soon after the masseter muscle was relaxed. This swelling was elastically soft, 40×40mm in size and without spontaneous pain or tenderness. Skin surface had normal color, and no fluctuation was felt. Two milliliters of vessel blood was aspirated by puncture. The intraoral examination revealed no abnormal findings.
An extended mass was found in masseter muscle with CT scanning and ultrasonic scanning.
Under the diagnosis of erectile hemangioma, the sized about 40×20×15mm was removed surgically and diagnosed histologically as a cavernous hemangioma.
The clinical symptom disappeared and there is no sign of recurrence.
