Myoepitheliomas are benign neoplasms of salivary glands derived from myoepithelial cells. These tumors can occur at any age but are most common in young adults. This tumor is usually located in the parotid gland and the minor salivary glands of the soft palate and represents less than 1% of all salivary gland tumors. The myoepithelioma is classified in the follow cells types: spindle, plasmacytoid, reticular, epitheliod, and clear, additionally, mixed histological forms are described. The plasmacytoid myoepithelioma from palate salivary glands is considered as a rare entity. A 45-year-old lady presented with an asymptomatic, well-circumscribed, solid mass located on the hard palate, which was gradually increasing in size. A clinical impression of Pleomorphic Adenoma was made which on histopathological examination revealed cords, clusters, and sheets of homogenous, large cells with plasmacytoid characteristics and a prominent eosinophilic cytoplasm. Ductal and acinar differentiation were absent thus ruling out the pleomorphic adenoma, whereas, features consistent with plasmacytoid myoepithelioma were evident.
