Acute necrotizing esophagitis in a patient with femur fracture.

Acute necrotizing esophagitis, also known as “black esophagus”, represents an infrequent and rarely suspected clinical entity. However, a growing number of cases have been reported worldwide since it was first described in 1990. This condition develops associated with severe concomitant diseases and is believed to be related to a transient poor esophageal perfusion. On endoscopy, it consists of typical blackish esophageal lesions with exudates similar to those found in severe caustic esophagitis, originating its name (black esophagus). We present a case of this entity in an aged patient with femur fracture in hemodynamically unstable situation.
