Black Esophagus: A Rare Case of Acute Esophageal Necrosis.

Acute esophageal necrosis (AEN) also known as necrotizing esophagitis or black esophagus is an extremely rare cause of upper gastrointestinal (GI) bleeding. This condition is considerably rare, and the exact pathophysiology of the development of AEN is still unclear. There is consensus that it is caused by a combination of esophageal mucosal injury due to gastric acid and ischemic injury due to vascular compromise. The management of AEN includes correcting the multitude of underlying predisposing conditions as well as agile symptomatic management and close monitoring for signs of hemodynamic compromise. We here present an interesting case of a middle-aged male patient who presented with hematemesis and underwent emergent esophagogastroduodenoscopy (EGD), which revealed severe necrotic esophagus. We also discussed the risk factors, pathophysiology, and management of AEN.
