IgD multiple myeloma with renal involvement: case report.
IgD multiple myeloma is a unique type of multiple myeloma which is characterized by increased serum IgD and IgD type M-component in immunoelectrophoresis. It frequently shows renal involvement but it is a rare form of myeloma. The distinctive features of IgD myeloma are the dominance in males, high frequency in younger persons, and the uncertain appearance of M-component in serum electrophoresis. We experienced 3 cases of IgD multiple myeloma with renal failure which required hemodialysis before IgD myeloma was diagnosed. It is important to consider IgD myeloma when treating the patients with renal involvement of unknown origin.
