Enteric duplication cysts are uncommon congenital anomalies that can occur anywhere along the alimentary tract. Foregut duplication cysts are the least common of enteric duplications and represent approximately one-third of alimentary tract duplications.1,2 They are most frequently found in the thorax and abdomen and only rarely occur in the head and neck. A review of the literature up to 2003 revealed only 21 enteric duplication cysts of the oral cavity, representing 0.3% of all enteric duplication cysts.1 Of those reported, the majority have been found in the tongue. Other described sites in the head and neck region include the floor of the mouth, epiglottis, hypopharynx, larynx, pharynx, and anterior aspect of the neck.3 Depending on the site of occurrence, the cysts may be asymptomatic or cause varying degrees of feeding and/or breathing difficulties.
