Neurilemmoma of the Masseteric Nerve in the Masseter Muscle: A Case Report

ABSTRACT

A case is reported of neurilemmoma of the right masseteric nerve in the masseter muscle. We experienced a 34-years-old male patient who had neurilemmoma in the masseter muscle caused by chronic irritation. Special stain using S-100 immunoperoxidase was useful in establishing the diagnosis in this case. The most important aspect of this case is the anatomical site of the neurilemmoma; this tumor was originated from the masseteric nerve and is the first case reported in the masseter muscle. The patient underwent surgical excision of the tumor and no recurrence occured.
