Introduction: Nasal schwannomas are very rare neoplasms. According to the literature, half of the schwannoma cases occur in the head and neck areas and only <4% occur in the sinonasal tract. So far, only a few cases have been reported. Case description: We present the case of a 50-year-old man who had dorsal nasal deformity at the root of nose since 5 months. Complete excision of mass was performed by giving dorsal incision through external approach under local anesthesia. Here, we discuss the clinical and pathological aspects of schwannomas arising at dorsum of nose. Conclusion: Although schwannoma of the nose is extremely rare, the possibility of their existence should be realized and included in the differential diagnosis of any dorsal nasal mass.
