Black esophagus or acute esophageal necrosis (AEN) is a rare cause of upper gastrointestinal (UGI) bleeding usually involving distal esophagus. Proximal esophageal involvement is quite rare. We present an 86-year-old female with active coronavirus disease 2019 (COVID-19) infection who came in with newly diagnosed atrial fibrillation and was started on anticoagulation. She subsequently developed a UGI bleed, which was complicated by inpatient cardiac arrest. Following resuscitation and stabilization, UGI endoscopy showed circumferential black discoloration of proximal esophagus, with distal esophageal sparing. Conservative management was instituted and fortunately, repeat UGI endoscopy two weeks later showed improvement. This describes the first case of isolated proximal AEN in a COVID-19 patient.
Keywords: cardiac arrest; esophageal necrosis; histopathology examination; upper endoscopy; upper gastro-intestinal bleed.
