Achalasia, alcohol-stasis, and acute necrotizing esophagitis: connecting the dots.

​Acute necrotizing esophagitis (ANE) or “black esophagus” is defined as a circumferential dark pigmentation of the esophagus on endoscopy and mucosal necrosis on histology. Due to its rarity, the etiopathogenesis of this alarming finding is poorly understood. We report a case of ANE in an alcoholic with achalasia and discuss the pathophysiologic insights gained from this unusual presentation.
