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. The present case required intubation for stridor and airway obstruction shortly after birth. 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.
