• Pleomorphic adenoma usually occurs in the salivary gland. Occurrence in the nasal cavity is very rare and none have been reported in the vestibule of the nose.A very rare case of pleomorphic adenoma in the right vestibule of the nose in a 62-yearold woman is reported. The mass was 2.5 cm×2.0 cm and was located under the right lateral cutis. The mass was surgically removed via an intranasal approach. Histopathological examination showed similarities to pleomorphic adenoma of the salivary gland. Origin of this pleomorphic adenoma seemed to be the anterior nasal gland because of its location.Previous reports of nasal pleomorphic adenoma are also reviewed. There were 41 prior cases in Japan. Most nasal pleomorphic adenoma is in the nasal septum. Only 4 cases were located on the lateral side of the nose.Differential diagnosis of intranasal masses is discussed. Reticulum cell sarcoma, hemangioma, melanoma and Wegener's granulomatosis occur more frequently than pleomorphic adenoma. Biopsy is the most reliable method of diagnosis, but there are two contradictory opinions about biopsy. One is that, biopsy should be performed to rule out malignancy. The other is that biopsy should not be done because it may cause concretion of nasal mucosae. Therefore, we thought that biopsy should be done only after careful clinical examination.
