Henoch-Schönlein syndrome is a hypersensitivity-related acute small-vessel vasculitis possibly related to immunization, insect bites, medications, infections, or certain foods. Henoch-Schönlein syndrome occurs most commonly in children between 3 and 10 years of age, but can occur in adults. The diagnosis is based on characteristic clinical signs and symptoms such as skin rash, arthritis involving the large joints, colicky abdominal pain, gastrointestinal bleeding, and hematuria. The gastrointestinal manifestations are thought to be related to edema and intramural hemorrhage. Gastrointestinal hemorrhage is mostly confined to the mucosa and submucosa. Most gastrointestinal manifestations are self-limited but can lead to infarction, perforation, or intussusception. While the findings in this case are characteristic of HSP, other vasculidities, infectious enteritis, and Crohns disease should be considered.
