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 anesthe￢sia. 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.
