[Black oesophagus, a rare event in intensive care unit].

We report a new case of acute necrotizing oesophagitis, diagnosing on a patient hospitalised in intensive care unit. This pathology is still a rare event; 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 necrotizing oesophagitis is primarily medical. The prognosis for patients who develop acute necrotizing oesophagitis is generally poor, even if one can hope for the cure without after-effect of it.
