Although patients with anorexia nervosa (AN) present with various gastrointestinal disorders, little has been understood regarding the incidence and pathophysiology of gastrointestinal ulcers related to AN. A 20-year-old woman with a past history of AN was hospitalized for further examination of dysphagia and chest pain. Her nutritional status was very poor as evidenced by very low body mass index. Esophagogastroduodenoscopy detected longitudinal and geographical ulcers in the entire circumference of the cervical and upper esophagus. Enhanced expression of autophagy-related proteins, LC3B and p62, was seen in the esophageal epithelium surrounding the active ulcers. Expression of these autophagy markers disappeared from the esophageal epithelium soon after the nutritional rehabilitation. Given the fact that starvation and malnutrition are potent inducers for autophagy, these findings suggest that autophagy might be involved in the development of gastrointestinal ulcers in patients with AN.
