Henoch-Schonlein purpura (HSP) is defined as a primary systemic vasculitis of small vessels characterized by predominantly IgA immune deposits on the walls of the capillaries, venulas, and arterioles. It typically involves skin, intestines, and glomeruli and is associated with arthritis and arthargia. HSP primarily affects children, and is less common among adults. It is has been studied extensively in children, but much less is known about its development in adults. Moreover the incidence, severity and clinical manifestations of HSP in adults differ from those of HSP in children. We report on five adult cases of HSP.
