Pleomorphic adenomas arise most commonly in the major salivary glands. It has rarely been described arising in the nasal cavity. A 65-year-old woman presented with a 9-month-history of left sided nasal obstruction. Endoscopic examination and computed tomographic scan revealed a lobulated tumor mass arising from the left bony nasal septum and clivus. It was removed endoscopically with endonasal approach. Histologic examination showed a lobular and duct-like structures consisting of a loose myxoid stoma consistent with characteristics of a pleomorphic adenoma. There was positive immunohistochemical expression of cytokeratin and S-100 protein which confirmed earlier histopathological diagnosis. We report a very rare case of pleomorphic adenoma originating from the nasal septum and clivus with a review of literature.
