A novel presentation of alcohol-induced gastric necrosis: a case report.

Acute gastric necrosis is a rare condition with unknown pathogenesis. Existing literature describes acute esophageal necrosis as a result of excessive alcohol use; however, it is more difficult to find literature on alcohol-induced gastric necrosis. This condition may present with epigastric tenderness, vomiting or diarrhea with findings of pneumoperitoneum, gastric pneumatosis and portal venous gas on computed tomography. These patients can have complications such as septic shock, peritonitis and death. In this case report, we discuss a patient with a history of alcohol abuse who presented with acute gastric necrosis. On endoscopy, this patient was found to have a black necrotic gastric fundus and unusual erythematous changes to the mucosa. Prior research has identified other findings of patchy or diffuse circumferential black pigmentation of esophageal mucosa in patients with alcohol-induced esophageal necrosis, otherwise known as black esophagus. This case report aims to describe this novel presentation of alcohol-induced gastric necrosis.
