We present an infant with generalized palpable purpura, arthritis and fever, whose findings were atypical for classic childhood Henoch-Schönlein purpura (HSP). By describing the clinical symptoms and prognostic differences seen in infants versus school age children, we encourage physicians to be aware of infantile HSP in their differential diagnosis when they encounter a non-toxic infant with generalized purpura.
