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.

Abstract

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
