Gastrointestinal manifestations of IgA-Henoch-Schonlein vasculitis commonly occur in 50–75% of patients (adults) with abdominal pain and bloody diarrhea. Gastrointestinal symptoms commonly present in patients with IgA vasculitis, although uncommon in adults, are more severe and often atypical. Gastrointestinal symptoms vary in intensity and a cautious laparotomy is required to rule out an acute abdominal condition.
