Henoch-Schonlein Purpura (HSP) is systemic vasculitis in children, hallmark by inflammatory infiltration of polymonuclear leukocytes in small blood vessels, followed by IgA1 immune deposits. HSP prevalence is approximately 3-27 cases per 100,000 children. The inflammatory process in HSP causes an ischemia and hemorrhagic process characterized by non-thrombocytopenia purpura, arthralgia, gastrointestinal problems, and kidney impairment. This process is called leukocytoclastic vasculitis. A 10-year-old boy came to ER of Dr. Sayidiman Magetan Hospital presenting with diffuse abdominal pain and purpura skin lesions in body.
