We describe three patients with severe refractory cutaneous polyarteritis nodosa, resulting in painful ulcers involving the lower limbs and causing toe necrosis. Due to the severity of the cutaneous manifestations, the three patients received intravenous immunoglobulins at a dose of 1 g/kg/day for 2 days monthly. After the second intravenous immunoglobulin infusion, skin signs dramatically improved and completely healed after the third intravenous immunoglobulin infusion. Our findings indicate that intravenous immunoglobulins can be included in a therapeutic strategy to treat refractory cutaneous polyarteritis nodosa.
