Abstract
Myoepitheliomas are rare tumors that represent about 1% of the salivary gland tumors. Most of them are benign, and only 10% are malignant, and the latter are called malignant myoepitheliomas or myoepithelial carcinomas. The first case of a malignant myoepithelioma was described in 1975, since then there has been a greater incidence of these tumors reported in the parotid gland. Its involvement of the hard palate is extremely rare, and there are only 8 cases reported in the world literature and with short term follow up. The present investigation reports a case of a patient with a malignant myoepithelioma on the hard palate, with bone destruction, successfully operated upon.
