Hypocomplementemic vasculitis and renal involvement

Hypocomplementic urticarial vasculitis is a disorder that not only affects the skin, but other organs as well. We are describing a patient with this rare disorder and serious renal involvement that was treated with immunosuppressive therapy with good response and stabilization of the renal function. We emphasize the fact that renal involvement can occur with this disease and that the renal involvement is of the immune-mediate type and cannot be considered as benign as thought in the past.
