Unusual case of acute oesophageal necrosis

Acute oesophageal necrosis is a rare clinical entity that commonly affects the distal oesophagus, giving it a characteristic black appearance. It is associated with a high mortality and predominantly impacts critically ill patients. In this case report, we present a male patient in his 50s with multiple comorbidities admitted for management of ketoacidosis. The patient was overall well appearing and remained haemodynamically stable throughout the entirety of his hospital course. Despite this, necrosis was found in the proximal, middle and distal portions of the patient's oesophagus. The presence of such extensive oesophageal injury was very atypical considering the lower severity of the patient's condition.
