Schwannomas of Nose, Oral Cavity and Pharynx

Abstract

Six cases of schwannomas arc described, two of the nasal cavity, two of the tongue, one of the hard palate and one of the pharynx (piriform sinus). A short review of the literature is made on the schwannomas occurring in the sites of these cases. The general comments on the reported cases are as follows: (a) There was no relation between these schwannomas and von Recklinghausen's disease. (b) All patients were adults, 25 to 65 years old. Four were women and two were men. (c) In three out of the six cases the tumor was pedunculated. (d) Recurrence, metastasis or malignant degeneration did not occur after surgical removal in any of the six cases, as it was verified by a follow-up of 2 to 5 years.
