The Black Esophagus.

Acute esophageal necrosis (AEN), commonly referred to as black esophagus, is a rare clinical condition resulting from a combination of ischemic insult and thromboembolic injury to the esophagus. It is characterized by the circumferential black appearance of the esophagus. The risk factors for the development of AEN include coronary artery disease (CAD), diabetes mellitus, hypertension, malignancy, and alcohol use disorder. The treatment is directed at correcting the underlying medical conditions, supportive measures, and gastric acid suppression. We present the case of a 60-year-old female with multiple medical comorbidities who was detected to have a black esophagus during the evaluation of anemia.
