Abstract
A 63-year-old woman with abdominal pain and melena developed a palpable, purpuric rash and acute kidney injury. Skin and kidney biopsy confirmed Henoch-Schönlein purpura. Upper endoscopy revealed diffuse, circumferential, black-appearing mucosa of the esophagus consistent with acute esophageal necrosis (AEN), also known as black esophagus. AEN is a very rare cause of gastrointestinal hemorrhage with a high mortality risk. To our knowledge, there have been no prior reports of AEN associated with Henoch-Schonlein purpura or other vasculitis.
