Pleomorphic adenoma of the buccal salivary gland: magnetic resonance imaging findings with differential diagnoses

The majority of minor salivary gland tumors are malignant. Of the benign tumors, pleomorphic adenomas are most common. The cheeks, lips, and gingiva are rarely sites of occurrence. A case of pleomorphic adenoma of the buccal salivary gland is presented here with a discussion of the importance of magnetic resonance imaging in demonstrating the extent of the lesion and establishing a differential diagnoses.
