Foregut duplication cysts are heterotopic rests of foregut-derived epithelium that are usually found in the abdomen and thorax but occur rarely in the head and neck. We describe the first case (to our knowledge) of a hypopharyngeal foregut duplication cyst containing both gastric and pancreatic tissue. The case involved a neonate who was born with stridor and cyanosis and who required immediate intubation because of airway obstruction due to a large hypopharyngeal mass. Magnetic resonance imaging and computed tomography were helpful in localizing the lesion. Direct laryngoscopy revealed a 4.5 × 2.5-cm mass in the hypopharynx, originating 2 mm above the esophageal inlet. The mass was excised, which is the treatment of choice. We also review the literature and discuss the pathogenesis of foregut duplication cysts.
