Heavy chain deposition disease (HCDD) is one of the renal monoclonal immunoglobulin deposition diseases, histologically characterized by the presence of nodular glomerulosclerosis and non-amyloidogenic deposits of monoclonal heavy chains without associated light chains [1]. In 1993, Aucouturier et al. [2] reported the first documented cases and defined the concept of HCDD. They suggested that the deletion of the first constant domain (CH1) of
-heavy chains is the hallmark of the disease. In 1992, Tubbs et al. [3] described two patients with nodular glomerulosclerosis with deposits of
-heavy chains unassociated with light chains, but used the term pseudo-
heavy chain deposition disease. In these patients, immunochemical analyses of abnormal IgG were not performed. Although >10 years have passed since its first documentation and definition of the concept of HCDD, reports of HCDD remain extremely rare [1 (and references therein),48]. The natural | Case |
