A 29-year-old man visited a local clinic with a stomachache. He was diagnosed with Helicobacter pylori (HP) infection by esophagogastroduodenoscopy, and HP eradication therapy was started at that clinic. However, one day after starting HP eradication therapy, he developed severe abdominal pain and presented to the emergency room of our hospital. He was admitted to our hospital for further examination and treatment. During the hospitalization, purpura appeared on his lower extremities. Esophagogastroduodenoscopy and colonoscopy revealed diffuse mucosal erosions of the esophagus, stomach, duodenum, ileum, and colon. Histological examination of biopsy specimens of the skin and duodenum led to the diagnosis of IgA vasculitis. After treatment with prednisolone, his abdominal symptoms and purpura successfully subsided. In conclusion, we experienced a patient who initially had typical endoscopic findings of IgA vasculitis in the upper and lower gastrointestinal tracts that changed over time. Of note, he developed very rare esophageal lesions.
