Myoepitheliomas consisting exclusively of myoepithelial cells, are very rare tumor that comprise 1% or less of salivary neoplasms and are generally benign. They occur, principally, in the parotid gland and infrequently in minor salivary glands. In its appearance and growth pattern, myoepithelioma resembles pleomorphic adenomas but is more aggressive thanpleomorphic adenoma. There are distinct histological and immunohistochemi calcharacteristics of the tumor which aid in the diagnosis. Treatment is the same as for pleomorphic adenoma and the surgical excision should include a margin of normal tissue. Myoepithelioma of the palate is uncommon and a case has not been reported in the Korean otorhinolarygologic literature. Herein, we report case of myoepitheliomaof the palate in a 53-year-old male who was treated by surgical excision with review of the literature. (J Clinical Otolaryngol 2014;25:265-270)
