PHARYNGEAL NEURILEMMOMA<subtitle>Report of One Case with Removal by Intraoral Approach</subtitle>

He added five of his own, and in 1949 Slaughter²reported four more, with a discussion of the differential diagnosis. This tumor was first described by Verocay³in 1908 and has been known by such names as neurinoma, peripheral glioma, and schwannoma. Stout⁴reported 52 cases in 1935 and proposed that the term neurilemmoma be used. These tumors arise from the nerve sheath of the peripheral nerve and, unlike neurofibroma, are usually single and do not undergo malignant change.
