Pleomorphic Adenoma with A Prominent Myoepithelial Cell Component: Case Report with Abbreviated Review of Literature

1. Abstract

Pleomorphic adenoma, also known as a mixed tumor, is the most common benign tumor involving salivary glands with the parotid and minor palatal glands being common sites of occurrence. Histologically, pleomorphic adenoma can exhibit a wide variation in epithelial and stromal components, such as myxoid, chondroid, osteoid, and clear, spindle-shaped, epitheliod or plasmacytoid myoepithelial cells. In this paper we present a brief focused review of the literature and a case report of a pleomorphic adenoma that involved both the hard and soft palates and featured a prominent plasmacytoid myoepithelial cell component.
