Black esophagus is a rare condition of the esophagus that manifests as endoscopic findings of black-colored esophageal mucosa, which is usually caused by acute esophageal necrosis. We report a case of alcoholic patient who developed black esophagus. The 85-yearold man was admitted to Severance Hospital due to copious hematemesis over 2 days. Upper gastrointestinal endoscopy showed black-colored mucosa in the distal esophagus. Endoscopic biopsies of the esophagus revealed necrotic tissue, without any viable cells. Follow-up upper gastrointestinal endoscopy performed after supportive care with a proton-pump inhibitor, sucralfate, and total parenteral nutrition resulted in the remarkable healing of the esophageal wall with no complications.
