Nasopharyngeal PA is very rare, and a total of 8 cases have been published to date. They are benign except for a rare “carcinoma ex pleomorphic adenoma” but are not always completely encapsulated and show a definite tendency to recur after excision, in which case recurrence represents local growth because of incomplete excision and not malignancy. Pleomorphic adenoma (PA) ranks as the commonly occurring tumor and constitutes up to two-thirds of all salivary gland neoplasms.1 Pleomorphic adenoma was first termed by Willis.2 In the earlier years, it was also referred as mixed tumor, enclavoma, branchioma, endothelioma, endochroma, etc. About 90% of these tumors occur in the parotid gland and 10% in the minor salivary glands.
