Schonlein-Henoch purpura (SHP) is a systemic microvascular inflammatory disease. It has peak at 4-7 years old, and adult onset cases are about 5% of all. Sometimes adult onset cases have severe courses such as intestinal perforation. In almost 100% of cases skin eruption occurs, but about 15% of cases gastrointestinal symptoms precede skin eruption. Local inflammation in gastrointestinal region reveals atypical gastrointestinal manifestations, irregular-shaped ulcer, edematous mucosa. Although it has been reported that gastrointestinal findings can be seen most commonly in the second part of duodenum, small intestinal endoscopy and capsule endoscopy enable us to observe all sites of the small intestine. The findings in small intestine in HSP cases are useful to understand the pathological features of vascular disease.
