Cervical esophageal obstruction by ectopic gastric mucosa.

A 5-year-old boy presented with dysphagia, and barium swallow revealed a narrowing in the upper esophagus. Biopsies of the circumferential lesion showed gastric mucosa. The heterotopic gastric mucosa was resected via a cervical approach. After resolution of a minor anastomotic leak, he remains asymptomatic 10 years following resection with no evidence of recurrence by esophagrams and endoscopy.
