We analyzed the immunoglobulin (Ig) heavy chain gene rearrangement in the peripheral blood lymphocytes of a patient with multiple myeloma (MM). Although the morphological and immunological examination did not reveal the presence of circulating plasma cells, a monoclonal Ig gene rearrangement was detected. This observation indicates that a monoclonal expansion of circulating B cells was present in the peripheral lymphocytes of this patient.

Abstract
We analyzed the immunoglobulin (Ig) heavy chain gene rearrangement in the peripheral blood lymphocytes of a patient with multiple myeloma (MM). Although the morphological and immunological examination did not reveal the presence of circulating plasma cells, a monoclonal Ig gene rearrangement was detected. This observation indicates that a monoclonal expansion of circulating B cells was present in the peripheral lymphocytes of this patient.
