Ectopic gastric mucosa in the cervical esophagus.

摘要

This study describes the clinical presentation and management of ectopic gastric mucosa (EGM) in the cervical esophagus. This is a case report of a 53-year-old male who presented with left-sided odynophagia of 3 months' duration. Office examination, including flexible fiberoptic laryngoscopy, was unremarkable. Direct larynogoscopy and rigid esophagoscopy revealed a 2 x 1-cm fleshy, red, and raised lesion in the cervical esophagus. The remainder of the esophagus was normal. Histologic examination of a biopsy specimen from the lesion showed a normal gastric epithelium consistent with the diagnosis of ectopic gastric mucosa. He was treated with 3 months of proton pump inhibitors, which resulted in complete symptom resolution. Patient was then switched to H2-blockers and has been symptom-free for one year. The medical literature regarding EGM in the cervical esophagus is reviewed with respect to its incidence, pathogenesis, clinical course, and management. In conclusion, EGM can occur in the cervical esophagus, and odynophagia is the typical presenting symptom. Adenocarcinoma developing within random, nonsyndromic EGM of the cervical esophagus is exceedingly rare. The primary mode of treatment is medical therapy.
