Henoch-Schönlein purpura (HSP) is a paediatric vasculitis, affecting several organs. Purpura is typically found on posterior surface of lower limbs and is more often associated with joint, abdominal and kidney involvement. The paper reports a case of HSP with mild cutaneous and abdominal manifestations, with genital involvement (haemorrhagic oedema of the penis that is more rarely described in literature), which was treated with oral steroid therapy that led to an optimal clinical response.
