Pleomorphic adenoma, also called mixed tumor, is the most common benign tumor of the salivary glands that mostly occurs in the parotid or submandibular glands, but may also occur in the minor salivary glands that are distributed throughout the oral cavity. The common sites of pleomorphic adenoma of the minor salivary glands are the palates followed by lips and cheeks. Here we report a case of this tumor presenting in minor salivary glands of upper lip in a 16 year old girl. The patient presented with a painless, mobile, circumscribed nodule, about 1.5 cm in diameter, slowly growing in size. The nodule was subjected to Fine Needle Aspiration Cytology (FNAC) and was found to be pleomorphic adenoma of minor salivary gland origin in upper lip. Complete excision was performed and the diagnosis was confirmed by histopathological examination. The aim of this article is to highlight the occurrence of pleomorphic adenoma as a differential diagnosis for the swellings in the upper lip.
