Abstract

Schwannomas are benign tumors derived from the Schwann cells of the nerve sheath. These are rare tumors that can be found in any part of the body although fewer than 4% of these tumors involve the nasal cavity and paranasal sinuses. Here, we present three cases of sinonasal schwannoma. The tumor masses were removed by endoscopic excision under general anesthesia. Pathological examination of the excised specimens confirmed schwannoma and the tumor cells were immunoreactive for S-100 protein. The patients are doing well with no evidence of recurrence.
