[A case of multiple myeloma (IgG, k) associated with hypertetraploid chromosomal abnormality].
A patient with multiple myeloma (IgG, k) associated with hypertetraploid chromosomal abnormality is reported. The patient was a 62-year-old female. She was admitted to our clinic in October 6, 1982 because of lumbago and a supraorbital subcutaneous tumor. Cellulose acetate membrane electrophoresis of her serum disclosed a M-protein in the gamma-globulin, and immunoelectrophoresis showed monoclonal IgG, k type. A marrow aspirate of her sternum contained 15% myeloma cells, some of which were large, while others were atypical. A chromosomal analysis of her bone marrow revealed 34 hypertetraploid cells of 35 metaphase cells. Chemotherapy was administered without success and she died of DIC and uremia on November 11, 1982. Histologically, pleomorphic myeloma cells that contained large cells with atypical nuclei proliferated in her bone marrow.
