Neurilemmomas are benign, solitary and well-encapsulated tumors which can arise from any cranial and peripheral nerves with neurilemmal sheath. These tumors most often occur in the head and neck region, but rarely in the nasal cavity or paranasal sinuses.

We have experienced a case of neurilemmoma which was presented as a nasal polyp. The stalk of the tumor was from upper anterior portion of the nasal septum and the involving nerve was thought to be the septal branch of anterior ethmoidal nerve. The tumor was excised by intranasal approach using nasal endoscope without recurrence.
