Immunotactoid glomerulopathy with leucocytoclastic skin vasculitis and hypocomplementemia: a case report

Immunotactoid glomerulopathy is a recently described entity characterized clinically by proteinuria, hematuria and hypertension, and on renal biopsy by various glomerular lesions including extracellular microtubules composed of immune reactants. Furthermore a defined immunological disease or cryoglobulinemia are absent. We report the case of a patient with immunotactoid glomerulopathy and hypocomplementemia (low C3 level) who developed several episodes of leucocytoclastic skin vasculitis with large immune deposits in and around small vessels. It is suggested that skin and renal involvement are part of the same systemic disease.
