[Multiple myeloma and terminal acute myeloid leukaemia (author's transl)].

A patient with multiple myeloma died of an acute myeloid leukaemia 15 years after onset of the former. At time of diagnosis the 39 year-old-patient had bone marrow infiltration of maximally 32 plasma cells/100 white bone marrow cells, a paraprotein (IgG, light-chain type lambda), osteoporosis of late onset and occasional osteolysis. The long survival time, as well as the acute myeloid leukaemia, are probably due to the effective treatment, first with cyclophosphamide (198 g over four years), later melphalan (3000 mg over eight years).
