We describe two cases of adult-onset Schonlein-Henoch purpura with gastrointestinal manifestations. Case 1: A 73-year-old man was admitted to our hospital because of abdominal pain, diarrhea and fever. On physical examination, the abdomen was normal, and there were many palpable petechial hemorrhages on the lower extremities.Skin biopsy revealed infiltrations of lymphocytes, neutrophils and eosinophils into the dermis. A computed tomographic (CT) scan of the abdomen disclosed thickening of the intestinal wall in the duodenum and jejunum.Upper gastrointestinal fiberscopy revealed petechiation on the stomach and erosions on the duodenum. Case 2: A 54-year-old man was admitted to our hospital because of hematochezia.The patient had pharyngitis 4 days before admission, and his serum anti-streptolysion O level was increased.On physical examination, there were faint purpuras on the lower extremities.Skin biopsy revealed a histological image of leukocytoclastic vasculitis. A CT scan of the abdomen disclosed thickening of the intestinal wall in the duodenum, jejunum and ileum.Gastrointestinal fiberscopy revealed petechiation on the stomach and ulceration on the cecum.
