Review Case Reports
Foregut duplication cyst of the hypopharynx: a rare cause of upper airway obstruction.
Foregut duplication cysts of the hypopharynx are extremely rare, and only 6 cases, all of which have been described as solid lesions and contained heterotopic gastric epithelium, could be found during our literature review. We present a unique case of a hypopharyngeal foregut duplication cyst that was grossly cystic and had no heterotopic epithelium microscopically. ⋯ Congenital laryngeal cysts can appear similar to this lesion. However, the hypopharyngeal location of a cyst is a clue for the diagnosis of duplication on endoscopic examination.
