title: Ectopic gastric mucosa in the cervical esophagus.
abstract: Ectopic gastric mucosa is a known entity of the mid and lower esophagus which was initially described by Schmidt in 1805. The presence of ectopic gastric mucosa in the cervical esophagus, however, was not described. A review of the literature reveals that ectopic gastric mucosa of the cervical esophagus is not uncommon, but symptoms rarely have been attributed to its presence. This paper reports five patients with isolated inflamed ectopic gastric mucosa in the cervical esophagus who presented with odynophagia and/or dysphagia. Physical examination was unremarkable in each case, and an acid barium esophagram was negative in four of five patients. Factors that distinguish these patients from other cases of odynophagia and dysphagia, as well as detailed clinical findings and treatment, are described. Debate exists as to whether the origin of ectopic gastric mucosa is congenital or acquired. The embryology, gross and microscopic anatomy, and pathologic features are outlined. Patients with persistent dysphagia should have flexible fiberoptic esophagoscopy with an index of suspicion to the existence of ectopic gastric mucosa. Inflamed or ulcerated ectopic gastric mucosa in the cervical esophagus should be treated to relieve symptoms and because of the potential for complications.
