A 72-year-old man was admitted to our hospital because of lumbago and numbness of legs. Tumor invasion at the fourth lumbar vertebra was revealed. Immunohistochemistry using specific antibodies against each heavy and light chain of immunoglobulin revealed that the myeloma cells in bone marrow were all IgA-lambda type whereas they were all positive for IgG-kappa type in a tumor of the fourth lumbar vertebra. These data indicate that the patient had IgG-kappa/IgA-lambda biclonal myeloma. Different phenotypes of M-proteins and distinct proliferating sites for two clones suggest that they may have resulted from two independent transforming events.

A 69-year-old man visited our department of neurology with symptoms of paresthesia on the lower extremities and lumbago. Biochemical examination of serum samples showed hypercalcemia (serum concentration 15.6 mg/dl). The levels of intact parathyroid hormone (i-PTH) and 1,25-dihydroxyvitamin D were suppressed, whereas parathyroid hormone-related peptide (PTHrP) was elevated up to 5.4 pM (normal range: below 0.6 pM). Additionally, bone survey revealed a punched-out lesion in radiological examinations of the skull. Bone marrow aspiration demonstrated many atypical plasma cells suggesting multiple myeloma. Nephrogenous cyclic adenosine monophosphate (cAMP), urinary deoxypyridinoline, plasma interleukin 6 (IL-6) and transforming growth factor beta (TGF beta) concentrations were elevated, whereas % of renal tubular reabsorption of phosphate (%TRP) was decreased. The immunohistochemical results demonstrated the expression of PTHrP in atypical plasma cells. These data indicated that hypercalcemia complicating multiple myeloma causes an elevation of renal calcium reabsorption and an increase of bone resorption mediated by PTHrP action.

Multiple myeloma associated with extramedullary plasmacytoma at initial presentation is rare. We describe a 45-year-old female patient with an initial presentation of low back pain and right side L5, S1 radiculopathy. There was no evidence of vertebral involvement but an epidural tumor was found later during neurosurgical intervention. The final diagnosis was immunoglobulin G, kappa multiple myeloma complicated with spinal root compression by an extramedullary plasmacytoma. No osteolytic lesion was noted over the length of the spine. Pathology revealed high-grade plasmablastic myeloma. During the clinical course, the patient was refractory to induction chemotherapy, and there was progressive deterioration of renal function. Urinary tract infection by Morganella morganii and pulmonary infection of unknown cause developed 5 months later, and the patient died.

A 43-year-old man with refractory myeloma underwent allogeneic bone marrow transplantation from his HLA-matched sibling. He was conditioned with TBI (12 Gy) followed by melphalan (140 mg/m(2) ). Immediately after conditioning was initiated, he began complaining of severe lumbago, and the level of serum calcium rose from 2.25 to 3.34 mmol / l. However, the biochemical markers for tumor-lysis syndrome such as potassium, uric acid, and lactic dehydrogenase remained unchanged. Hydration with saline and pamidronate were started, but he developed acute renal failure requiring hemodialysis for 3 weeks. His plasma parathyroid hormonerelated protein (PTHrP)-NH2-terminal (3.9 pmol/l) and serum PTHrP-C-terminal (125.0 pmol / l) levels markedly increased immediately after conditioning. These results suggested that the increased release of PTHrP from myeloma cells, which resulted from destruction of myeloma cells by conditioning, was the primary contributes to the occurrence of hypercalcemia. We should be aware of the occurrence of hypercalcemia when high-dose therapy is to be given to patients with refractory myeloma.

A 71-year-old woman with an 8-year history of IgG-kappa type multiple myeloma was admitted because of severe lumbago and bone destruction. Her serum IgG level was elevated to 5,565 mg/dl at admission. Despite treatment with doxorubicin, vincristine, dexamethasone, melphalan and interferon-alpha, the response was transient. Nine months later, multiple skin nodules appeared on her chest, abdominal wall and right thigh accompanied by elevation of the serum IgG level. Response to combination chemotherapy with cyclophosphamide, ranimustine, vincristine and prednisolone was also transient. The skin tumors on the bilateral thighs, especially on the left side, acquired chemotherapy resistance and gradually enlarged. Although the serum IgG level was maintained by chemotherapy within the range 1, 790-2,676 mg/dl, the skin tumors on the left thigh had spread very rapidly and appeared "rock-like". The enlarged tumors caused necrosis with erosions and oozing hemorrhage. A skin biopsy from the tumors on the left thigh showed plasmacytoma in which infiltration of large anaplastic plasma cells was observed. The patient died of sepsis 8 months after the skin tumors initially developed. This is a very rare case of multiple myeloma in which multiple large plasmacytomas of the skin developed and grew aggressively at the terminal stage after a long-term indolent course.

A 45-year-old male was admitted because of chest pain, lumbago, and bilateral ankle pain. Examination disclosed hypophosphatemic osteomalacia, acquired Fanconi syndrome, and abnormalities in distal nephron such as distal renal tubular acidosis and renal diabetes insipidus. Further exploration revealed IgA kappa multiple myeloma excreting urinary Bence Jones protein (kappa-light chain). Renal biopsy revealed thick basement membranes and elec-tron-dense crystals in proximal tubular epithelial cells. Immunofluorescent studies revealed deposition of kappa-light chain in renal tubular epithelial cells that caused the renal tubular damage. Although the osteomalacia was relieved by medical treatment, the urinary Bence Jones protein and the renal tubular defects were not improved by the chemotherapy for the myeloma. The patient died of exacerbation of multiple myeloma at 50 years of age.

Two cases of solitary plasmacytoma of bone (SPB) were diagnosed. The first case was a 41-year-old woman, complaining of fatigue from her lumbar region to her legs. The second case was a 56-year-old man complaining of poor gait and severe lumbago with numbness in the toes of both feet. Magnetic resonance imaging showed the osteolytic lesion in the 12th thoracic bone in the first patient and around the 2nd, 3rd and 4th lumbar bones in the second patient. In both patients serum analysis revealed the monoclonal component of immunoglobulin G (IgG) protein with kappa-light chain, and considering this and other findings SPB was diagnosed. Both patients were first treated with irradiation around the involved bone and then with a course of chemotherapy. In the first patient the tumour region of the bone was surgically removed and replaced with a ceramic spacer. The symptoms of both patients were ameliorated, and the patients remained in good condition for around 3 years without conversion to multiple myeloma. In view of the overall effectiveness of treatments for SPB, our therapeutic strategy deserves careful evaluation.

The association of sarcoidosis with Hodgkin disease and non-Hodgkin lymphoma is well known. However, multiple myeloma also can occur rarely in association with sarcoidosis. We describe a patient with sarcoidosis who subsequently developed multiple myeloma. The patient was a 49-year-old woman with a 4-year history of severe, chronic, active sarcoidosis involving her lungs, lymph nodes, eyes, and bone marrow. During the initial clinical workup, a serum monoclonal paraprotein was detected and bone marrow examination revealed a slight increase in plasma cells (4%), in addition to noncaseating granulomas. Thus, the diagnoses of monoclonal gammopathy of undetermined significance and sarcoidosis were established simultaneously. She sought medical attention for her current illness when she developed low back pain and weakness of her lower extremities. Serum protein electrophoresis and immunofixation revealed a monoclonal paraprotein, immunoglobulin (Ig) G kappa type, and quantification revealed an IgG level of 46.67 g/L (normal, 5.88--15.73 g/L). Bone marrow aspiration and biopsy revealed multiple myeloma and sarcoidosis. Including this patient, 11 cases of sarcoidosis and multiple myeloma have been reported to date, including 3 patients with monoclonal gammopathy of undetermined significance preceding the onset of multiple myeloma. In this case, as in most of the cases reported previously, sarcoidosis preceded the development of multiple myeloma.

A 54-year-old man diagnosed with IgD myeloma (stage IIIA) in complete remission (CR) received peripheral blood stem cell transplantation (PBSCT) twice with an interval of 4 months using high-dose melphalan 200mg/m2. However 9 months after the second PBSCT, he was readmitted because of lumbago, lower left hemiparesis, speech disturbance and left facial nerve palsy. A lumbar puncture revealed myeloma cells in the cerebrospinal fluid (CSF). The patient did not respond to any salvage chemotherapy and died of sepsis 27 months after the initial diagnosis. The findings in this patient suggest that another treatment modality including prophylactic intrathecal injection of an anti-cancer drug as well as allogeneic cell therapy is probably necessary in patients with high-risk IgD myeloma.
