Abstract
A 43-year-old male visited to our hospital with epigastralgia and nausea. Endoscopic examination was performed on January 16, 1993 and it revealed two reddish ulcerative lesions situated longitudinally at 32cm from the incisors in the posterior wall of the esophagus. Histopathological study of the biopsied specimens revealed cardiac gland tissue in connection with the normal esophageal squamous epithelium and diagnosed as ectopic gastric mucosa in the esophagus. Endoscopic examination performed on March 12, 1994 showed marked decrease in size of the distal legion. These findings were considered as a result of the defect of the esophageal mucosa which was replaced with columnar epith-elium, and this evidence might be in a process of being gradually replaced with squamous epithelium again. Thus, this case was considered to be an important one in the healing process of the esophageal mucosal injury.
