Myoepithelial cells that express both epithelial and smooth muscle phenotype have a potential to differentiate into various cytomorphologic forms such as spindle, plasmacytoid, epitheloid and clear cells. Salivary gland tumors composed entirely or almost exclusively of myoepithelial cells are referred to as myoepitheliomas. They may be benign or malignant in nature and about 90% of them are benign and only 10% are malignant. The palate is the most common intraoral site of occurrence for both the variants. In this paper, we report one case of myoepithelioma occurring on the palate and two cases of myoepithelial carcinomas, one seen on the palate and the other rare case seen on the alveolar mucosa, along with an elaborate review on benign and malignant myoepitheliomas of salivary glands along with their ultra-structural, cytological and immunohistochemical profiles.
