Abstract:
Myoepithelioma is a rare tumor that occurs most frequently in the parotid gland, the palate, and the breasts, although it has also been found in the submandibular gland, the lips, the gingiva, the lacrimal gland, the cheeks, and the external auditory canal. Of all the salivary gland tumors, myoepithelioma accounts for less than 1% of the total. Clinically, myoepithelioma resembles mixed tumors in its appearance and growth pattern. However, a malignant variant of this tumor is extremely unusual. The most common treatment for myoeithelioma is the conservative excision which usually accompany a marginal amount of uninvolved tissue. In this study, we report two cases of myoepithelioma, a parotid gland tumor and a submandibular gland tumor. Histologic features showed that the former was composed of hyaline cells and the latter was composed of spindle cells.
