Abstract:
Myoepitheliomas of salivary gland occur infrequently and are generally benign. Malignant myoepitheliomas of salivary gland are extremely rare tumor, and increasing number of case reports have shown that malignant myoepitheliomas may either arise de novo or develop in a pre-existing pleomorphic adenoma. In our case, myoepitheliomas was located in the parotid gland, and tumor cells displayed morphological features of spindle & epithelioid cells. Their clinical behavior by literature seems variable. This case dealt with malignant myoepithelioma of the parotid gland in a 65-year-old man with a relatively favourable course, and was followed up for 2 years and 5 months. In addition, this case illustrates some of the characteristic clinical and pathological features of this rare tumor.
