Schwannomas are neurogenic neoplasms which are rarely found in the sinonasal tract, and onl 77 cases have been reported in Japan. We present a case of schwannoma occurring in the lef nasal cavity, review the current literature and discuss the clinical details with specif histological features. The patient was a 48-year-old man, who complained of nasal discharge on the left side and headache. On endoscopic examination, the left nasal cavity was occupied with a polypous mass. CT scan of the paranasal sinus revealed that the tumor occupied the left nasal cavity and was pressing out the internal wall of the left maxillary sinus and nasal septum. Biopsy of this polypous mass showed it to be only an inflammatory granulation. Under general anesthesia, the tumor was completely resected by endoscopic sinus surgery (ESS) . Histological examination revealed it to be schwannoma (Antoni A type). The postoperative course was good with no signs of recurrence for 6 month.
