title: Development of a transient monoclonal gammopathy after chemotherapy in a patient with biphenotypic acute leukemia.
abstract: The development of a IgGk monoclonal gammopathy after a phase of bone marrow aplasia following chemotherapy is described in a patient suffering from biphenotypic acute leukemia (BAL). Paraprotein was followed by the relapse of the disease and disappeared during a further chemotherapy. Paraprotein could have been caused by an additional chemotherapy-induced genetic mutation or by a dysfunction in T-B cooperation observed in the phase of reconstitution of the immune system after medullar aplasia.
