Myoepithelioma of a Minor Salivary Gland of the Palate: Case Report

Myoepithelioma is a rare neoplasm of salivary glands, generally occurring in the parotid and less often in the minor salivary gland of the oral cavity. Vimentin and S100 protein are very sensitive but nonspecific immunohistochemical markers of neoplastic myoepithelium. This report is a rare case of myoepithelioma of the palate of a 25-year-old woman who suffered the disease for two years. The numerous phenotypic expressions of the myoepithelial cell, associated with the rarity of this tumor, may challenge the pathologist.
