Schwannoma is a benign, slow-growing tumor originating from nerve-supporting cell. Approximately 25-40% of schwannomas develop in the head and neck region. However, only about 4% occur in the sinonasal tract. This study presents a rare case of nasal schwannoma along with a review of the relevant literature. We discuss a 54-year-old woman with no underlying diseases who presented with left-sided nasal obstruction and recurrent epistaxis for 2 months without nasal discharge, hyposmia/anosmia, or headache. Sinus computed tomography imaging showed a mass in the nasal cavity attached to the left inferior turbinate and nasal endoscopy revealed a protruding mass in left nasal cavity. Endoscopic-assisted wide excision and partial turbinectomy were performed under local anesthesia, with no recurrence noted 6 months postoperatively. Endoscopic-assisted surgery is a viable option for selected patients due to cosmetic considerations. Given its rarity and the difficulty of diagnosis based solely on physical examination and imaging, we present this case and describe the most relevant epidemiological and clinical characteristics of nasal schwannoma.
