Salivary gland tumors can be divided into three types: benign, locally aggressive, malignant tumors with potentiated to metastasize. Pleomorphic adenomas are the most common benign tumor of the major salivary glands. Infrequently, it may arise from the minor salivary glands and present as an intraoral mass over the palate or lip. We report a case series of five pleomorphic adenoma, with three cases involving hard palate and two involving of upper lip.
