Abstract

Pleomorphic adenomas are the most common salivary gland tumors. Of the majorsalivary glands, the predominant location is the parotid gland. Common sites of pleomorphicadenomas of the minor salivary glands are the palate, lip and buccal mucosa. Thoughpleomorphic adenoma occurs in the upper lip, it seldom occurs in the lower lip. We reporta 23-year-old female with a pleomorphic adenoma of the low lip. We do not know the re-ason why pleomorphic adenomas occur more frequently in the upper lip than the lower lip. However, there are definite differences in the distribution of the minor salivary glands betweenthe upper and lower lip, and we believe that this is one of the causes why pleomorphicadenomas seldom occur in the lower lip.
