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 Â 1.8 Â 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
