Compared to leukemia, malignant lymphoma and other hematogenous tumors, multiple myeloma rarely metastasizes to the central nervous system. Intracerebral metastasis without involvement of the cranium itself is rarer. We report a case of Ig-G k-type multiple myeloma with metastasis to the left frontal lobe extending to the right basal ganglia without involvement of the cranium. A 71-year-old male complained of exertional dyspnea and lumbago. His laboratory data revealed hyperproteinemia and an abnormal increase in Ig-G (6117mg/dl) in his serum. Serum protein immunoelectrophoresis revealed an IgG k-type band, and Bence-Jones protein was detected in his urine. MMPP, VMCP, VIPP and MP chemotherapy was given, and serum IgG level decreased to a normal range. 21 months after his first admission, incontinence, disorientation, gait disturbance and apathy developed. CT-scan showed an isodense lesion with massive edema in the left frontal lobe and right basal ganglia. On MRI, a Gd-DTPA enhancing lesion was detected extending from the left frontal to the opposite frontal lobe through the splenium. No abnormal skull punched out lesions were noted. Left frontal lobectomy was performed. Histopathology revealed plasmablastic myeloma cells with clear nucleole and eccentric nucleus in the cerebrum. He was diagnosed as having intracerebral metastasis of multiple myeloma without involvement of the cranium. Unfortunately, he died of pancytopenia and pneumonia. Our case suggests the possibility of metastasis via blood into the cerebrum.

A 71-year-old man was admitted because of right cervical lymph node swelling in February 1986. Lymph node biopsy revealed that he suffered from diffuse, large cell malignant lymphoma. Immunological staining showed lymphoma characterized by B cell markers, IgG, kappa type. Bone marrow aspiration, revealed no evidence of lymphoma and 0.2% plasma cells. The clinical stage was IIA. The patient was treated with the CHOP regimen (doxorubicin, cyclophosphamide, vincristine and prednisolone), which achieved complete remission. In October 1988, he was re-admitted because of a subcutaneous abscess, and biopsy of the inguinal lymph node showed reactive lymphadenitis. Although he improved with antibiotic therapy, laboratory date on admission showed monoclonal gammopathy. Serum immunoelectrophoresis demonstrated a monoclonal bow of IgA kappa type, and bone marrow aspiration revealed hypercellularity with an increased number of plasma cells (76.8%). The patient was diagnosed as having multiple myeloma, and combination chemotherapy was begun. He now attends the out-patient department at our hospital. The development of multiple myeloma has not been reported previously during a course of malignant lymphoma. Although the association of these two B cell neoplasias was unknown, in this case both showed the characteristic of kappa type light chains. This case may provide information concerning tumor cell origin.

A 71-year-old man was hospitalized in November, 1983 for a back pain and a diagnosis of multiple myeloma was made, based on the Bence Jones proteinuria, The serum M-component of a IgG-kappa type (3.3 g/dl), and plasmacytosis in the bone marrow (37%). Treatment consisted of melphalan and prednisolone. A blood count in March, 1986 revealed 6000/microliters of WBC with 30% of a blast form and 8% plasma cells, and 20,000/microliters of platelets. A bone marrow aspirate revealed that 14% were myeloblasts and 26% were plasma cells. Distinguishing the myeloblasts from the immature plasma cells in the peripheral blood proved difficult. Studies by electron microscopy and an immunological inspection of phenotypes were helpful in achieving a determination. A karyotypic analysis of the bone marrow cells indicated a hypodiploid cell population, a marker chromosome, and a karyotypic instability. These findings indicate that his multiple myeloma had undergone a leukemic change associated with acute myelogenous leukemia.

A 71-year-old woman with multiple myeloma was successfully managed for 8 years with melphalan (total dose 2056 mg). She developed a refractory anemia (myelodysplastic state), which terminated in acute eosinophilic leukemia. This form of acute leukemia, induced by chemotherapy, appears to be very rare. The cytogenetic changes, including 5q- and monosomy 7, were similar to those observed in other patients with acute nonlymphocytic leukemia as a secondary malignancy following treatments of other primary tumors.

A 71-year-old woman with IgG multiple myeloma presented initially with a compression fracture of the thoracic spine. She responded to radiation therapy and chemotherapy with melphalan and prednisone. One year later, she died from a plasmacytoma eroding intracranially from the greater wing of the sphenoid bone with an associated subdural hematoma. Uncal herniation had been preceded for several weeks by facial numbness. Cranial and intracranial plasmacytomas may occur as isolated lesions or as part of multiple myeloma and can present clinically in a variety of ways, most frequently with cranial nerve palsies. Large intracranial extensions may produce cerebral compression and spontaneous hemorrhage similar to that seen with other malignant intracranial neoplasms. The differential diagnosis of changes in level of consciousness in myeloma patients should include increased intracranial extension and spontaneous hemorrhage.

A 69-year-old man (Patient 1) complained of anorexia, lumbago, and seeing floaters OS. The results of laboratory tests showed immunoglobulin (Ig) G lambda-type multiple myeloma associated with blood hyperviscosity. Retinal hemorrhages OD and central retinal vein occlusion OS were found. A 71-year-old woman (Patient 2) with IgG kappa-type multiple myeloma had blood hyperviscosity. Retinal microaneurysms OD and central retinal vein occlusion OS were found. We believe that our patients represent rare cases of IgG multiple myeloma associated with blood hyperviscosity and central retinal vein occlusion.

A 71-year-old woman, known to have multiple myeloma, was admitted because of fever, abdominal pain and hyperamylasaemia and hyperamylasuria. She was diagnosed as having acute pancreatitis. Because the diagnosis could not be confirmed, and serum lipase was normal, it appeared that this patient had developed an amylase-producing myeloma lesion in the pelvis.

A 71-year-old female with primary biliary cirrhosis, multiple myeloma and hypothyroidism is reported. The liver biopsy showed stage II-III histologic damage according to Scheuer's classification and the multiple myeloma was IgG-lambda type, stage II-A at the time of diagnosis. Another three cases of primary biliary cirrhosis associated with multiple myeloma were found in the literature. As a group, the four cases had mild or moderate liver damage, extensive bone lesions and three of four cases had multiple myeloma IgG-lambda type. Although this association could be incidental, there is evidence that implies a pathogenic relationship. This information is summarized in this report.

A 71-year-old woman with multiple myeloma (MM) in remission was admitted for evaluation of recent abdominal distension and was diagnosed as having massive myeloma ascites. The fluid was characterized by a total nucleated cell count of 6,600/mm3 (67% plasma cells), with a plasma cell CD38+ phenotype. Chemical analysis of the fluid showed lactate dehydrogenase of 122 IU/L, total protein of 2.9 g/dL, albumin of 2.4 g/dL, diastase of 38 IU/dL, cholesterol of 46 mg/dL, and C-reactive protein of 3 g/dL. The serum-ascites albumin gradient (SAAG) was low (0.9). Electrophoresis of the ascitic fluid showed a monoclonal spike in the gamma region and immunoelectrophoresis confirmed the presence of lambda light chains similar to those seen in the urine. Further analysis of the ascitic fluid showed markedly elevated levels of beta2 microglobulin (11,161 microg/L) and interleukin-6 (146 pg/ml compared to serum level of 4.3 pg/ml). There was evidence of intraabdominal masses that completely resolved with continuous high-dose cyclophosphamide (750 mg/m2/day for four days) followed by clinical improvement and disappearance of the ascites. We stress the value of complete fluid characterization and intensive chemotherapy to achieve a favorable outcome.

Recently, there have been several reports describing patients with multiple myeloma complicated by consciousness disturbance due to hyperammonemia. Here we report a patient with multiple myeloma and hyperammonemia, who died after rapid progression of the disease. A 71-year-old man who had been diagnosed as having Bence Jones protein (kappa)-type multiple myeloma in 1996 was readmitted to our hospital in February 1997 because of worsening bone pain, renal dysfunction, and hypercalcemia. Bone marrow aspiration yielded an almost dry tap, and the bone marrow was found to be completely occupied by immature plasma cells. Although liver dysfunction was slight, the serum ammonia level was high and increased gradually. Despite treatment, the patient died due to cerebral embolism and progression of plasmacytic leukemia in October 1997. Peripheral blood sampled at the time of death showed a serum ammonia level of 204 micrograms/dl, and the myeloma calls were cultured using monolayered bone marrow stromal cells as feeder cells. This led to the successful establishment of a cell line. The level of ammonia in the supernatant was high, indicating that the cultured myeloma cells produced and released ammonia.
