Intranasal pleomorphic adenomas are quite rare and are frequently misdiagnosed . We report a nasal septal pleomorphic adenoma in a 60-year-old man. Rigid endoscopy of the nose revealed a large polypoid mass filling the right posterior nasal cavity. Computed tomography scan of the paranasal sinuses demonstrated well-pneumatized paranasal sinuses and a soft tissue mass in the posterior aspect of the right nasal cavity arising from the posterior part of the septum. A submucous resection was used as an approach to the tumor and as a method of excising the mass with the segment of septum attached to it. After 4 years, the patient had experienced no further problems with the nasal airway, and repeated nasal endoscopic examination revealed no recurrence of the disease.
