       A rare case of low grade malignant myoepithelioma arising in the minor salivary gland of the palate is reported. A 46-year-old man presented with a palate mass. Surgical resection was performed. Histological examination indicated that the tumor organized in the myoepithelial cells and showed signs of mitosis. Immunohistochemical studies showed positive staining for S-100 protein and cytokeratin. For nine months post operatively, there has not been any evidence of recurrence.

Key words : malignant myoepithelioma, palate, minor salivary gland, immunohistochemical studies
