Lymphoepithelial cyst of the oral cavity is a rare cyst, and histopathologically is generally lined by parakeratinized stratified epithelium, showing lymphoid tissue in the submucosal connective tissue. We report herein a case of lymphoepithelial cyst on the lateral border of the tongue. The patient was a 73-year-old woman. Intraoral examination revealed an asymptomatic, yellowish-white mass on the left border of the tongue. The mass was excised under local anesthesia and the histopathological diagnosis was lymphoepithelial cyst. We present a rare case of lymphoepithelial cyst on the lateral border of the tongue with a brief discussion of the differential diagnoses. •Lymphoepithelial cyst of the oral cavity is a rare cyst.•Histopathologically is generally lined by parakeratinized stratified epithelium.•Lymphoid tissue is shown within submucosal connective tissue.•The patient was a 73-year-old woman with an asymptomatic, yellow-white mass on the left border of the tongue.
