Pleomorphic adenomas usually occur in the major salivary glands, and rarely in the nasal septum.We describe here a rare case of a Pleomorphic adenoma originating from the nasal septum treated by endoscopic nasal surgery. A 77-year-old man was admitted to our hospital because of epistaxis. The rhinoscopic examination showed a vascularized nasal polyp-like mass located in the nasal septum. It was elastic in consistency. Endoscopic examination revealed a smooth-surface mass measuring 2 x 2 cm in diameter. Nasal axial contrast-enhanced CT scan demonstrated a well circumscribed solid mass with a slightly enhanced rim in the right nasal cavity with no evidence of bone destruction. The patient underwent adequate surgical excision using nasal endoscopy. On histologic examination, the specimen was found to be a pleomorphic adenoma. Thereafter, the patients showed no evidence of recurrence at more than one year later. It is concluded that endoscopic nasal surgery is a useful option for a pleomorphic adenoma of the nasal cavity.
