Myoepithelioma possibly originating from the accessory parotid gland.
Myoepithelioma originates almost exclusively from myoepithelial cells of the salivary, prostate and mammary glands. The skin is a very rare site where myoepithelioma occurs. We describe a patient with a myoepithelioma on the right cheek seen as a subcutaneous nodule that was separated from the parotid gland at surgical resection. Histopathological findings were consistent with those of a myoepithelioma that had originated from the parotid gland, suggesting that this tumor may have developed from the accessory parotid gland.
