Congenital oral cysts of foregut origin include bronchogenic, enteric, and oesophageal cysts, and they are much rarer than the well described dermoid, epidermoid, and thyroglossal cysts. The exact aetiology is poorly understood, but they are thought to arise from misplaced embryonic rests of the primitive foregut. The presentation of cysts lined by respiratory or gastrointestinal epithelium in the oral cavity is unusual. There have been previous reports of bronchogenic or gastrointestinal epithelium-lined lingual cysts, but few report both features occurring within the same cyst. In view of the scarcity of such reports, we present the case of a lesion on the ventral surface of the tongue of a newborn boy. On removal it was found to be a cyst lined by immature squamous, respiratory, and gastric body epithelium.
