title: Lymphoepithelial cysts of oral mucosa: two cases in different regions.
abstract: Lymphoepithelial cyst of the oral cavity is a rare cystic lesion that presents as an asymptomatic, well-circumscribed, yellowish small submucosal nodule covered by normal overlying mucosa, usually located in the floor of the mouth or in the ventral or posterolateral surface of the tongue. Histopathological examination reveals a cyst lined by a stratified squamous epithelium surrounded by lymphoid tissue. In this paper, we report two cases of oral lymphoepithelial cyst, one on the anterior floor of the mouth and another on the posterior lateral tongue. In both cases, the patients were women aged approximately 50 years and the lesions were treated by local surgical excision, with no evidence of recurrence after 2 years of follow-up.
