Lipoma can arise in any portion in the body where fat tissue is exist. However, lipoma in the oral cavity is rare and reported to occur only in 2～5％ of benign tumor in the oral cavity in Japan. We treated a 66-year-old female with a lipoma of the tongue. Oral examination revealed a 27×23 mm mass on the left edge of the tongue. The mass was firm on palpation. A T1 weighted axial MR image clearly showed a hyperintense mass with a small area of isointensity. The tumor was excised under general anesthesia. It was encapsulated and measured 50×30×25 mm in size. The histopathologic diagnosis was lipoma with muscle components. A review of the Japanese literature showed 55 cases of lipoma of the tongue.
