A 63-year-old man was admitted because of general malaise, fever, headache, generalized lymphadenopathy and hepatomegaly in July 2002. He was diagnosed as having multiple myeloma (MM) (IgG-κ type) with atypical plasma cells in the bone marrow, lymph nodes and cerebrospinal fluid. Systemic and intrathecal chemotherapy were effective. Because of an increase of polyclonal IgE, electrophoretic patterns revealed an M-peak which was not as sharp as that in IgG myeloma. IgE production is not impaired by the pathologic process in MM patients.
