title: Submandibular gland myoepithelioma.
abstract: Benign myoepithelioma is a very rare form of salivary gland tumor, composed entirely of myoepithelial cells. It accounts for approximately 1% of all salivary gland tumors and is most frequently located in the parotid gland and in the minor salivary glands of the hard palate. We describe herein the ninth reported case of myoepithelioma of the submandibular gland. Benign myoepithelioma must be differentiated from several benign and malignant epithelial and mesenchymal tumors. Immunohistochemical staining can help differentiate between these conditions, but histopathology remains the gold standard for diagnosing this neoplastic process.
