PG - 1127-32 AB - A case of immunoglobulin E (IgE) myeloma with clinical features of "classic" myeloma is presented. Skeletal roentgenograms showed osteoporosis and compression fractures of the vertebrae but no osteosclerosis. Protein analyses revealed an M component of the IgE kappa type with a concentration of 3.1 g/dl. Although morphologic examination revealed that the plasma cells were not so differentiated, well-developed Golgi apparatus and abundant rough-surfaced endoplasmic reticulum were observed. An indirect immunofluorescence technique showed characteristic apple green fluorescence. The E myeloma protein of our patient had no antibody activity. Treatment with melphalan or cyclophosphamide resulted in a decrease in the serum IgE level and in the level of Bence Jones protein in the urine. The clinical and laboratory features of IgE myeloma were summarized and compared with those of other classes of myeloma.
