[Abstract]
Acute necrotizing esophagitis (ANE) is known as the "black esophagus." We present a case of ANE in a patient with slowly progressive type 1 diabetes mellitus. A 49-year-old man presented with vomiting, characterized by coffee residue-like emesis, and was diagnosed with diabetic ketoacidosis. Upper gastrointestinal endoscopy revealed black mucosa extending from the middle of the esophagus to the gastric junction, leading to a diagnosis of ANE. The patient was treated with proton pump inhibitors and showed marked improvement. The patient was discharged on the 20th day of illness.
