Lymphoepithelial cyst of the nasogenian sulcus: a case report.
A rare case of lymphoepithelial cyst formed in the nasogenian sulcus is reported. Lymphoepithelial cysts are comprised of a stratified squamous epithelial lining above dense lymphoid tissue. They are uncommon in the oral region and, to our knowledge, have never been reported in the nasogenian sulcus. Surgical excision was performed and no recurrence was noted after 6 months. In this report, we describe the etiopathogenesis of lymphoepithelial cysts, as well as the differential diagnosis of nasogenian sulcus swellings.
