Lymphoepithelial Cyst in the Sublingual Region: Report of a case and review of literature

Abstract

Oral lymphoepithelial cyst occurring in the sublingual region of a 30-year-old Japanese man is reported. This is a rare lesion that develops within oral lymphoid tissue. Clinical and pathological findings of our case show almost the same appearance as the cases which were reported previously. Serial sectioning was done in this case. We observed the salivary duct structure in the lymphoid tissue. We concluded that the histopathogenesis of this lesion is Bhaskar's “enclavement theory”.
