A 74-year-old woman complained of dysphagia and hemoptysis after ingesting a fragment of crab shell while eating crab salted-fermented fish products, and presented dyspnea that had lasted for three days. Computed tomography indicated pneumomediastinum. Laboratory results revealed acute renal failure. The patient experienced respiratory distress and shock over the days following her initial presentation. Upper gastrointestinal endoscopy revealed black pigmentation of the esophageal mucosa from the middle to lower esophagus. Despite intensive care, the patient's condition deteriorated and she died. This is the first case of acute esophageal necrosis associated with esophageal foreign body injury and the development of pneumomediastinum reported in Korea.
