The black esophagus and duodenum: a rare case report

Acute esophageal necrosis is a rare esophageal disease, typically characterized by the circumferential black appearance of the esophagus mucosa that usually affects the distal esophagus. It commonly affects the elderly man with multiple comorbidities. In medical literature, some cases have been reported about acute necrotizing esophagus, but according to our knowledge, no case has been reported about a patient with ischemic duodenum and esophagus. We describe the case of a 71-year-old man with an upper gastrointestinal bleeding and subsequently acute necrotizing esophagus and duodenum.
