CHUQUISANA-MOSTACERO, Celso; ENRIQUEZ DE SALAMANCA-CELADA, Javier  e  AZORIN-CUADRILLERO, Daniel. Two cases of duplication foregut cyst in oral cavity. Cir. plást. iberolatinoam. [online]. 2017, vol.43, n.2, pp.179-185. ISSN 1989-2055.

Background and Objective: The foregut cyst is a rare congenital disease. However when it appears its location is, most of the times, in the ileum and although it can be present throughout entire digestive tract, it is rare in the oral cavity. Usually, it is characterized by three major features: presence of a well developed smooth muscle layer, a typical epithelial layer of some portion of the alimentary tract, and an intimate join to any part of the gastrointestinal tract. The most common mouth floor cysts in childhood are salivary cysts and lymphatic malformations. Both of them designed within the term ranula. Although there are other possibilities, and foregut duplication is one of them, as we present in our clinical cases. Methods: We present 2 patients in pediatric age with tongue or mouth floor masses, who after respective radiological study, were operated by transoral approach to remove the tumor. In one of the cases transcervical approach was used to remove a second cyst locus. Results: The pathological study showed respiratory epithelium in one case, and gastric mucosa and respiratory epithelium in the second case. Conclusions: The importance of diagnosis and complete surgical removal in this clinical condition is supported by the risk of malignant degeneration in adult age.
