A Case of Schwannoma in Subfrontal Area and Nasal Cavity

Schwannoma is a benign solitary neoplasm emerging from the Schwann cells of the peripheral, cranial and autonomic nerves. Approximately 25 to 45% of schwannomas occur in the head and neck region. However, schwannoma in the subfrontal area, nasal cavity or paranasal sinus is very rare and accounts for only 4% of these neoplasms. We experienced a case of schwannoma in the subfrontal area and left nasal cavity in a 74-year-old man who complained of recurrent rhinorrhea. We report this unusual case of schwannoma with a review of the literature.
