title: Palpable purpura, polyarthritis and abdominal pain.
abstract: We report a patient who presented with a purpuric rash and polyarthritis, but IgA deposits were not found in the skin. Abdominal pain and renal disease first emerged 1 and 2 weeks, respectively, after presentation, to reveal the classic tetrad of Henoch-Schönlein purpura. Our patient emphasises the need for careful follow-up in patients with cutaneous vasculitis, as they may develop systemic manifestations, of which renal involvement, particularly, may be asymptomatic.
