Acute esophageal necrosis: a case report and review.

Acute esophageal necrosis, commonly referred to as "black esophagus" or "acute necrotizing esophagitis", is a rare clinical disorder with an unclear etiology. The definition excludes patients with a history of recent caustic ingestion. Oesophageal necrosis can be diagnosed at endoscopy by the presence of black necroting appearing oesophagus. Contrary to the caustic oesophagitis whose treatment is often surgical, treatment of the acute necrositing oesophagitis is primarily medical. The prognosis for patients who develop acute necrotizing oesophagitis is generally poor. We report a new case of acute necrotizing oesophagitis and undertook a literature review of this rare diagnosis.
