[A further case of IgD myeloma (author's transl)].

A 76-year-old woman was hospitalized for stabilization of her diabetic condition. The results of radiological, hematological, and biochemical investigations suggested the diagnosis of an IgD myeloma. A specific immune-serum was used to demonstrate the presence of monoclonal protein of the IgD lambda type. The course of the disease was very rapid and death occurred within 19 days from acute renal failure. The authors emphasize the various factors demonstrating the original nature of this observation and conclude by insisting on the necessity to use anti-heavy chains delta and epsilon during the diagnostic investigations for minoclonal gammapathies.
