Myoepithelioma is a rare form of salivary gland tumor composed entirely of myoepithelial cells. It represents about 1 to 1.5% of all salivary gland tumors and is most frequently located in the parotid. The authors present a case of myoepithelioma of the gingiva. The tumor presented a focal strong positivity for cytokeratins, a diffuse positivity for S– 100 protein, and a rare focal positivity for actin. No duct formation was observed. Myoepithelioma must be differentiated from several benign and malignant epithelial and mesenchymal tumors. J Periodontol 1999;70:683‐687.
