[Generalized IgG-lambda plasmocytoma and stenosis of a Cimino shunt caused by plasma cell infiltration].
A 56-year-old apparently healthy man was on routine examination found to have a paraproteinaemia, classified as an IgG-lambda plasmocytoma in stage 1 on the basis of a raised IgG level (1950 mg/dl) and partly binuclear plasma cells in bone marrow. When 5 months later the IgG concentration had increased to 2980 mg/dl and the proportion of plasma cells in bone marrow to 15%, treatment was begun with melphalan (0.25 mg/kg) and prednisolone (2 mg/kg), both on 4 successive days every 6 weeks. The patient's general condition rapidly worsened after 6 months. The extent of osteolysis increased, necessitating radiotherapy of the vertebrae as well as a change in treatment to vincristine, cyclophosphamide, doxorubicin and prednisolone. At that time renal failure set in. But the prophylactically placed Cimino shunt had become infiltrated with plasma cells causing shunt stenosis and soft-tissue swelling. The infiltration was reduced by irradiation with 18 Gy. Numerous bluish skin discolorations now appeared and plasma cell infiltrates were shown in lung and pleura, as well as in the abdomen. The patient died 15 months after the diagnosis had been made.
