[An elderly patient with IgD myeloma associated with renal amyloidosis and acute renal failure].
A 83-year-old male patient with IgD myeloma associated with renal amyloidosis and acute renal failure is described. We also reviewed the clinicopathological findings of IgD myeloma in the literature. Although hemodialysis was performed 36 times for acute renal failure, he died of severe gastrointestinal bleeding. Renal necropsy specimens revealed typical features of amyloidosis in light microscopic, electron microscopic and immunofluorescent examinations. The levels of serum IgD (755 mg/dl), immunoelectrophoresis, and immunofluorescence of bone marrow and renal specimens were consistent with IgD myeloma (lambda type). IgD myeloma is generally considered to be a rare disease of juvenile onset and is complicated with extramyelogenic tumors according to previous reports. However, IgD myeloma without extramyelogenic tumors occurred in a 83-year-old patient reported here. It appears that advanced age onset IgD myeloma associated with renal amyloidosis and acute renal failure is rare. This was the oldest case of IgD myeloma we examined.
