Endoscopic resection of nasal schwanomma as a diagnostic and therapeutic adjunct in the treatment of a rare disorder: A case report with literature review

Abstract

Isolated nasal schwannomas are rare lesions that can be difficult to diagnose due to nonspecific characteristics. We report a unique case of a patient with a polypoid mass abutting the lacrimal sac found to be a nasal schwanomma. A 66-year-old male with a history of previously resected nasal polyposis returned to the office complaining of symptoms suggestive of rhinosinusitis. Endoscopy was significant for a polypoid mass superior to the inferior turbinate. CT imaging revealed a 2 × 1.8 × 1.3 cm lesion in the right nasal cavity with bony erosion overlying the lacrimal sac. Following endoscopic resection, pathologic analysis revealed a nasal schwanomma based on S100 and Ki-67 staining patterns. The patient has been doing well for over 6 months without recurrence. Although rare, nasal schwanomma should be kept in the differential of any nasal mass, and endoscopic resection can serve as a useful tool in the management of this disorder.
