The lingual cyst with respiratory epithelium (LCRE) is a congenital cyst of the tongue or floor of mouth that is lined predominately by respiratory-type epithelium. The terminology for this lesion was first proposed by Manor et al. in 1999, who stated that a descriptive term is best for this cyst of debatable pathogenesis. Although it is a cyst of foregut origin, the LCRE is distinguished from the traditional enteric (foregut) duplication cyst in that the latter contains gastric and/or intestinal-type mucosa and has smooth muscle within the cyst wall. This article presents two new cases of this entity as well as reviews the nineteen cases in the literature that were found to fulfill the histologic criteria of a LCRE.
