Myoepithelioma is a rare benign tumor of the myoepithelial cells, constituting 1.5% of the salivary gland tumors with equal frequency in men and women. It occurs in the range of 9–85 years. It is most common in the parotid gland and the hard and soft palate. It may contain acellular mucoid or hyalinized stroma and the tumor cells are unable to form ducts (None, <5–10% or <1 duct/HPF). A case of myoepithelioma has been reported.
