Gastric choristoma of the hypopharynx presenting in an infant: a case report and review of the literature.

Normal gastric mucosa has been found throughout the alimentary tract, ranging from scattered rests of cells to well formed mucosa with submucosal smooth muscle. Many terms have been applied to these collections; however, the term gastric choristoma seems most appropriate. We present a case of hypopharyngeal gastric choristoma presenting with dysphagia and frequent emesis. Our literature review reveals that this is the seventh reported case of gastric choristoma found in the hypopharynx, and the first to present in an infant in the absence of respiratory distress. Excision or CO(2) laser ablation is useful for symptom relief; however, complete removal often requires multiple attempts.
