Henoch-Sch枚nlein purpura (HSP) is an immune mechanism leukocytoclastic vasculitis with small vessel involvement. It affects children, mainly males, in 90%of cases.. The four main clinical features include purpura rash, abdominal pain, arthralgia and renal involvement.
HSP is usually self-limiting in 94%of children and 89%of adults. Treatment is basically symptomatic for joint involvement and abdominal pain.
The interest in this case lies in the rarity of this disease in adults, which may be more serious since there is an increased risk of chronic renal impairment.
