[An autopsy case of IgE myeloma].
An autopsy case of IgE myeloma, 85-year-old male is reported. He was admitted to our hospital on November 17, 1987 due to pain of left humerus. Osteolytic and osteoporotic foci were found in left humerus, ribs, spinal column and femurs. Complete blood countings were as follows: RBC 3.23 x 10(12)/L, Hb 11.3 g/dl, WBC 6.3 x 10(9)/L, platelet 173 x 10(9)/L. Blood smear showed red cell rouleaux formation without myeloma cells. Examination of bone marrow revealed hypoplasia with 52% myeloma cells which were stained with anti-IgE and antilambda antisera by peroxidase anti-peroxidase method. Total serum protein level was 7.7 g/dl. Monoclonal protein was observed at fast gamma-region by cellulose-acetate electrophoresis. On immunoelectrophoresis, this monoclonal protein made specific M-bow against anti-IgE and anti-lambda antisera. The IgE level in serum and urine were 7.8 x 10(6) IU/ml and 2.4 x 10(3) IU/ml by radio-immunoassay respectively. He was died owing to renal failure on September 7, 1988. Postmortem examination showed infiltration of myeloma cells in bone marrow, spleen, kidneys, lungs and generalized lymph nodes.
