Pleomorphic Adenoma of the Upper Lip: A Rare Case.

Salivary gland tumors account for a small fraction of head and neck tumors. Pleomorphic adenoma, the most common salivary gland neoplasm, frequently arises in major salivary glands; its localization to minor salivary glands is uncommon and typically involves the palate. We describe a patient with an asymptomatic, long-standing mass of the upper lip, which was found to be a pleomorphic adenoma.
