Oral foregut cyst in the ventral tongue: a case report

Abstract: An oral foregut cyst is a rare congenital choristoma lined by the respiratory and/or gastrointestinal epithelium. The exact etiology has not been fully identified, but it is thought to arise from misplaced primitive foregut. This lesion develops asymptomatically but sometimes causes difficulty in swallowing and pronunciation depending on its size. Thus, the first choice of treatment is surgical excision. Surgeons associated with head and neck pathology should include the oral foregut cyst in the differential d… Show more

“…This type of cyst may be diagnosed considering the morphology solely, following recommendations previously reported. 3 It is essential to highlight that the epithelium would be diffusely positive for CK7 if the immunohistochemical analysis is performed 14 ; for this reason, immunohistochemical analysis is not usual. 3 Considering the histologic presentation, the differential diagnosis of the lingual cysts must embrace epidermoid, dermoid, teratoid, and thyroglossal duct cysts, lingual thyroid, hemangioma/lymphangioma, mucocele or ranula, and lymphoepithelial cysts.…”

“…These cysts, also called choristomas, contain heterotopic islands of gastrointestinal mucosa that is usually gastric but occasionally intestinal, colonic or pancreatic. The duplication of this mucosa is based on a triad of (1) a cyst covered by a smooth muscle coat, (2) the presence of epithelium derived from the foregut, and (3) attachment to a portion of the foregut, which gives this entity its name [4], [5], [6], [7], [8].…”
