Abstract:
Gurvits syndrome, black esophagus or acute esophageal necrosis (AEN) is a rare and multifactorial disorder resulting from a combination of ischemic insult, corrosive injury of the mucosa from gastric contents, and impaired reparative mechanism in the setting of acute illness. The diagnosis is made by visualization of a circumferential black discoloration of the distal oesophagus that abruptly ends at the gastroesophageal junction. We report a case of Gurvits syndrome secondary to diabetic ketoacidosis (DKA).
