Hemangioendothelioma of the Masseter; A Case Report

(Nikko Memorial Hospital)
Hemangioma is common in the head and neck area, but intramuscular hemangiomas are rare. We report a case of hemangioendothelioma of the masseter.
A 26-year-old male with swelling of the left cheek was referred to the Department of Otolaryngology of Nikko Memorial Hospital. The mass had appeared three month before and had gradually become bigger during the previous week. On physical examination, a 4.8 cm x 4.6 cm tumor mass was palpated in the left cheek. The mass could be freely mov-ed from side to side but not vertically.
A horizontal slightly curved upper cervical incision was made 2 to 3 cm below the angle of the mandible. The masseter muscle was dissected and the mass was removed en bloc along with a few strands of skeletal muscle. The postoperative course is uneventful and facial palsy did not occurr.
The mass was diagnosed pathologically as hemangioendothelioma of the masseter.
