ABSTRACT
Myoepithelioma is histologically composed exclusively of myoepithelial cells. Myoepithelial cells are present in the major and minor salivary glands. Salivary gland neoplasms that frequently contain myoepithelial cells are the pleomorphic adenoma, adenoid-cystic carcinoma, and epithelial myoepithelial carcinoma of intercalated duct origin. Neoplasms composed exclusively of myoepithelial cells are rare. Myoepitheliomas may be composed of spindle-shaped cells, plasmacytoid(hyaline) cells, or combination of both in varying proportions. A case is reported of plasmacytoid myoepithelioma with ultrastructural confirmation, together with reviews of the English literature.
