    Abstract:
    Schwannoma is a benign neoplasm originating from schwann cells of the peripheral nerve sheath, and its occurrence in the nasal cavity and paranasal sinuses is rare. We present a case of nasal schwannoma originating from the left nasal cavity, accompanied by bilateral nasal polyposis. A 66-year-old man presented with complaints of progressive left nasal obstruction, hyposmia, and headache. Anterior rhinoscopic and endoscopic examinations revealed a mass that almost completely filled the left nasal cavity. A polypoid mass was present in the right nasal cavity, as well. On computed tomography, the mass occupied the left ethmoidal cells, left maxillary sinus, left sphenoid sinus, and posterior area of the left nasal cavity. Endoscopic sinus surgery was performed under general anesthesia and the mass was completely removed via the nasopharynx because of its size. Endoscopic anterior ethmoidectomy was also performed in the right nasal cavity for nasal polyposis. Histopathological diagnosis of the left nasal mass was schwannoma. The patient was symptom-free with no recurrence after nine months.
