An Unusual Presentation of Pleomorphic Adenoma - A Case Report

Salivary gland swellings can result from tumors, an inflammatory process or cysts. It can sometimes be difficult to establish; whether pathology arises from the salivary gland itself or adjacent structures. Neoplasms of the salivary glands account for less than 1 % of all tumors, 35 % of all head and neck tumors and benign pleomorphic adenoma (PA) of minor salivary glands arising de novo is very rare. PA is the most common tumor of the salivary gland. While the majority arises from the parotid gland, only a small percentage arises from the buccal minor salivary gland. A case of PA of minor salivary glands in the buccal mucosa in a 70-year-old female is discussed. It includes review of literature, clinical features, histopathology, radiological findings and treatment of the tumor; with emphasis on diagnosis.
