Henoch-Schönlein purpura (HSP), the commonest vasculitis in children, occurs most frequently between the ages of 4 and 6 years. We report the case of a 3-year-old boy with an otomastoiditis who was treated with cephalosporin and corticosteroids following a typical purpuric skin rash diagnosed as HSP. The patient also developed an acute occurrence of impairment of the glans, prepuce and penis 4 days after recovery that completely disappeared after a further 2 days, with the cutaneous rash subsiding on discharge from hospital.
