A 65-year-old man was admitted to our hospital in September 1997 because of back pain and renal dysfunction. He was diagnosed as having multiple myeloma due to the presence of IgD lambda monoclonal gammopathy and diffuse infiltration of plasma cells in the bone marrow. The patient achieved a partial response to DMVM-IFN-alpha combination therapy. His condition worsened in December 1998, but was ameliorated by VAD therapy. The patient's left testis became enlarged in December 1999, and an orchiectomy was performed. The normal testicular cells had been entirely displaced by myeloma cells comprising typical plasma cells and large lymphoid cells. Pleural, mediastinal, spinal, and right testicular involvement with myeloma subsequently developed. Despite attempts to treat the patient with more than one type of combination therapy, his condition worsened progressively, and he died in June 2000. Reports of IgD myeloma with testicular involvement are rare. The histopathology of our patient's resected testis, i.e. the two myeloma cell-plasmacytoid and lymphoid cell components showing differential immunostaining, was unique.

A 74-year-old woman was admitted to our hospital in March 1998 for low-back pain. In 1990, she had a chemotherapy for diffuse mixed cell lymphoma. Biochemical and serologic assays revealed a total protein level of 9.7 g/dl and an IgG level of 4,530 mg/dl. Immunoelectrophoresis showed monoclonal IgG protein associated with two monoclonal kappa and lambda light chain components. Bone marrow examination showed proliferation of myeloma cells comprising up to 25% of all nucleated cells. Myeloma cells were immunohistochemically positive for IgG and kappa and lambda light chains. IgG contained equal amounts of IgG 1 and IgG 2 subtypes and the complementarity determining region 3 (CDR 3) of myeloma cells showed oligoclonality by polymerase chain reaction, suggesting the myeloma cells may have two components. The patient received melphalan and prednisone in combination, resulting in only a minor response. She eventually developed angioimmunoblastic T-cell lymphoma. Biclonal gammopathy associated with malignant lymphoma is rare in case of multiple myeloma and may provide some insight into the pathogenesis of plasma cell tumors.

Nonsecretory multiple myeloma (NSMM) is a rare variant of the classic form of multiple myeloma (MM) and accounts for 1% to 5% of all cases of MM. The clinical presentation and radiographic findings of NSMM and MM are the same. The diagnosis of MM requires the detection of a monoclonal gammopathy in the serum or urine. In NSMM, however, no such gammopathy can be demonstrated, making the diagnosis more difficult. We describe a 43-year-old African American woman who initially had back pain and pathologic vertebral compression fractures that were thought to be due to osteoporosis. Five months later, hypercalcemia developed and NSMM was diagnosed. No monoclonal gammopathy was found in the serum or urine, but skeletal survey showed diffuse osteolytic lesions, and bone marrow biopsy revealed marked plasmacytosis. The immunohistochemical techniques and chromosomal analysis methods that are currently available are discussed.

Bone pain, especially back pain, is a common presenting feature of myeloma patients. We report three multiple myeloma patients with exacerbations of back pain and referred shoulder pain resulting from vertebral infections. Two patients were treated with surgery, and one patient had computerized tomography-guided percutaneous needle aspiration for diagnostic purposes. All three patients received a prolonged course of antibiotics. Vertebral infection resolved with this treatment in all three patients without any recurrence. Previous dexamethasone therapy, together with an episode of bacteraemia, appears to be a predisposing factor for vertebral infection. Magnetic resonance imaging enabled the diagnosis in all three patients.

Hyperphosphatemia, in patients with multiple myeloma, is usually associated with severely reduced renal function. Paraproteins can interfere with the measurement of serum inorganic phosphate when certain types of automatic methods are employed. We present the case of a 44-year-old male admitted to our hospital with severe back pain and an osteolytic lesion of the first lumbar vertebra. He was diagnosed with multiple myeloma based on serum protein electrophoresis and bone marrow biopsy results. An initial serum phosphate level of 12.5 mg/dl, (normal 2.5-5 mg/dl), in the setting of normal kidney function, did not improve after treatment with oral phosphate binders. The inorganic phosphate determinations were repeated on sulfosalicylic acid deproteinized serum samples, yielding normal range phosphate levels. This case reiterates the importance of using deproteinized serum samples for phosphate measurements in patients with multiple myeloma, normal renal function and elevated phosphate levels, before initiating therapy with phosphate binders.

A 76 year old lady presented with altered sensorium and was found to have hyperammonemia on evaluation. She had no evidence of liver disease. For her symptomatology of backache, evaluation by bone marrow study showed evidence of multiple myeloma. She was given chemotherapy for multiple myeloma, which resulted in improvement in her sensorium, along with this there was also a rapid decline in serum ammonia levels. Hyperviscosity and hypercalcemia are common causes of altered sensorium in a patient with myeloma but in this case hyperammonemia was the likely cause.

Percutaneous vertebroplasty is emerging as one of the most promising new interventional procedures for relieving (or reducing) painful vertebra, with the injection of surgical polymethylmethacrylate or cement into vertebral bodies. This imaged-guided technique, originally used to treat vertebral hemangioma, has recently been extended to the treatment of metastases, osteoporotic compression fractures, and vertebral myeloma. It is increasingly being accepted as a main treatment of choice in the management of resistant back pain due to vertebral compression fractures, especially in the elderly individual who is not a candidate for surgery. In this article, we review indications, contraindications, technique, and complications of percutaneous vertebroplasty.

Inspite the new informations about the physiology and biochemistry of pain, it remains true that pain is only partially understood. Cancer pain is often experienced as several different types of pain, with combined somatic and neuropathic types the most frequently. If the acute cancer pain does not subside with initial therapy, patients experience pain of more constant nature, the characteristics of wich vary with the cause and the involved sites. Chronic pain related to cancer can be considered as tumor-induced pain, chemotherapy-induced pain, and radiation therapy-induced pain. Certain pain mechanisms are present in cancer patients. These include inflammation due to infection, such as local sepsis or the pain of herpes zoster, and pain due to the obstruction or occlusion of a hollow organ, such as that caused by large bowel in cancer of colon. Pain also is commonly due to destruction of tissue, such as is often seen with bony metastases. Bony metastases also produce pain because of periostal irritation, medullary pressure, and fractures. Pain may be produced by the growth of tumor in a closed area richly supplied with pain receptors (nociceptors). Examples are tumors growing within the capsule of an organ such as the pancreas. Chest pain occurring after tumor of the lung or the mediastinum due to invasion of the pleura. Certain tumors produce characteristic types of pain. For example, back pain is seen with multiple myeloma, and severe shoulder pain and arm pain is seen with Pancoast tumors.

Adult Burkitt's lymphoma is an uncommon disease. Few cases of spinal involvement in adults with sporadic Burkitt's lymphoma are reported in the literature. We present a case of a middle-aged man who was found to have an epidural mass in the thoracic spine when investigated for back pain and lower extremity weakness. He underwent a laminectomy with resection of the epidural mass. Histologic examination revealed a primary Burkitt's lymphoma of the spinal cord. He was treated with aggressive chemotherapy and is now experiencing remission of his disease. We also present a review of the literature for the etiology and clinical features of other spinal lymphomas and Burkitt's lymphoma involving the spine in adults.

Total 14 cases of myeloma in young age group (<40 years) have been reported out of 178 cases of myeloma in a time period of 7 years (1993-1999). Males predominated overfe males. Like adult myeloma, patients presented mostly with the backache, pain in pelvis, lower spine and weakness in about 60% of cases followed by swelling of bone in 40% of cases. One case presented with bleeding gum, malena and hepatosplenomegaly and was diagnosed as plasma cell leukemia. Radiological examination revealed lytic lesion in almost all the cases with fracture femur and rib in 28.57% of cases. Anaemia and raised ESR was noted in all the cases. Myeloma typing revealed IgG myeloma in 10 cases, light chain myeloma in 3 cases and IgA myeloma in one case. None of the patient was traceable after 2 years. Thus our study concludes that myeloma in the young age in India occurs in increased frequency and clinically presents just like adult and elderly myeloma, but serologically are predominantly of IgG type. There is also an increased frequency of solitary plasmacytoma as compared to adult myeloma.
