Introduction
Light chain deposit disease (LCDD) [1] is an uncommon monoclonal gammopathy which should be considered carefully in patients who have both renal disease and a lymphoplasmacytic disorder capable of producing monoclonal light chainsmyeloma, macroglobulinaemia, lymphoma, chronic lymphatic leukaemia [24]. The diagnosis is straightforward when monoclonal light chains are present in the serum and/or urine and the renal biopsy shows characteristic morphological changes and stains clearly for kappa or lambda light chains. The diagnosis of LCDD is often difficult as patients may not have a known or demonstrable lymphoplasmacytic disorder [35], monoclonal light chains may be detectable only intermittently and at low concentrations in the serum and/or urine [
