Hypersensitivity Vasculitis

Hypersensitivity vasculities is sometimes called leukocytoclastic vasculitis. Its symptoms are similar to Henoch-Schönlein purpura. However, hypersensitivity vasculitis affects persons who are older. It usually isn't accompanied by the abdominal pain and digestive disorders that occur with Henoch-Schönlein purpura.
