Acute Esophageal Necrosis: A Case of Black Esophagus with DKA.

Acute esophageal necrosis is a rare cause of upper gastrointestinal bleeding, usually caused by hypoperfusion. In this report, we present a 34-year-old male patient suffering from acute esophageal necrosis presenting as hematemesis in a patient with Diabetic ketoacidosis. Diabetic ketoacidosis is rarely reported as a cause of acute esophageal necrosis and it is vital to diagnose it in a patient with Diabetic Ketoacidosis as a potential cause of mortality.
