Sinonasal schwannoma with secondary changes.

Schwannomas of the Sinonasal tract are very rare, representing less than 4% of schwannomas arising in the head and neck [1]. The most frequent site is the acoustic nerve; other locations include the scalp, oral cavity, pharynx, larynx, trachea, parotid gland, and middle ear. Secondary changes in a Schwannoma are a very rare entity. We report a case of Sinonasal schwannoma with pseudoangiomatous changes. The purpose of this article is to highlight the possibility of unusual presentation of a sinonasal schwannoma.
