Acute esophageal necrosis (AEN), commonly referred to as "black esophagus", is a rare clinical entity also known as Gurvits syndrome (1-3) (Figures 1-3). Acute esophageal necrosis arises from a combination of ischemic insult seen in hemodynamic compromise and low-flow states, corrosive injury from gastric contents in the setting of dysmotility (esophago-gastroparesis) and gastric outlet obstruction, and decreased function of mucosal barrier systems and reparative mechanisms present in malnourished and debilitated physical states (1). Not uncommonly, diabetic ketoacidosis (DKA) also results in this condition. Less commonly, infections such as aspergillosis may also turn the esophagus black (Table below).

Gurvits syndrome or 'black esophagus' is caused by microvascular thrombosis and neutrophilic inflammation (ischemic necrosis) (2). Microvascular thrombosis is related to various entities, including hemodynamic shock, vasculitis, antiphosolipid syndrome, immunological impairment, malignancy, diabetes mellitus, alcoholism (2) (Table). Histology shows mucosal/submucosal necrosis, dense neutrophilia, edema, sloughed epithelium, and debris.
Therapy of Gurvits syndrome is focused at reversing the underlying clinical conditions, such as restoring hemodynamic perfusion, treating sepsis, and improving oxygenation. The patient is initially kept NPO (nil-per-os), and aggressive intravenous acid suppression with proton pump inhibitors is warranted (1, 2). Complications include perforation with mediastinal infection/abscess, esophageal stricture and stenosis, superinfection, and death, which can be as high as 32% (1, 2).
