Carcinoma ex pleomorphic adenoma (CXPA) is a rare salivary gland malignancy most often reported within the parotid gland. Of the salivary gland tumours that occur within the minor salivary glands at least 50% are reported to be malignant. This proves to be inaccurate when describing salivary gland tumours within the upper lip which are usually benign. A Medline search of the English language literature yields only one case report of a CXPA located within the upper lip. The authors present a second case report of CXPA within the upper lip and a review of its pathologic features and management.
