A 53-year-old woman was admitted to this institution with chest pain and dyspnea. Chest roentgenogram showed pleural effusion and multiple tumor shadows, bilaterally which represented extrapleural signs. Numerous atypical plasma cells were found in the pleural effusion. Bone marrow biopsy showed atypical plasma cells. Immunoelectrophoresis revealed monoclonal Bence-Jones protein-lambda in serum and urine. Myeloma was subsequently diagnosed and chemotherapy was started. Multiple myeloma is a plasmacytoma, and myeloma cells proliferate in the bone marrow. The incidence of myeloma associated with malignant pleural effusion is rare with only 33 cases previously reported in Japan, to the best of our knowledge.

We report here two Japanese cases of rheumatoid arthritis (RA) associated with IgA [symbol: see text]-type multiple myeloma (MM). Case 1. The patient was a 68-year-old man with eight-years history of RA. The M-proteinemia (IgA 2838 mg/dl) in laboratory findings suggested a complication of MM which had been noticed since four years ago. On May 1997, he was referred and admitted to our hospital because of cough, right chest pain and dyspnea. Serum immunoelectrophoresis showed monoclonal IgA[symbol: see text]-type light chain. Bone marrow aspirate contained 6.5% atypical plasma cells. The X-ray findings revealed radiolucent myelomatous foci in the skull. From these findings, IgA[symbol: see text]-type MM was diagnosed. His condition was recovered by administration of antibiotics for bacterial pleuritis. Case 2. The patient was a 75-year-old woman with twelve-years history of RA. The laboratory findings of M-proteinemia (IgA 1215 mg/dl) with the decrease of other serum immunoglobulin level (IgG 611 mg/dl, IgM 60 mg/dl) and monoclonal IgA[symbol: see text]-type light chain in serum immunoelectrophoresis suggested MM four years ago. Bone marrow aspirate contained 5% plasma cells. From these findings, IgA[symbol: see text]-type MM was diagnosed. In the review of reported Japanese cases of RA associated with MM, it might be characteristic that IgA type MM was found more frequently in RA patients than other immunoglobulin types.

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.

A 53-year-old man was admitted to Keio University Hospital because of serious dyspnea and edema of the lower extremities. Eighteen months previously, the patient had complained of chest discomfort, and was then admitted for the first time to our hospital for evaluation of chest pain. Electrocardiography showed poor R wave progression in leads Vl through V4, and diffuse nonspecific ST-segment and T wave abnormalities with low voltage. However, no definitive diagnosis could be made at this initial admission and a calcium-channel blocker was prescribed. Despite this treatment, the patient was readmitted with worsening dyspnea and lower extremity edema. The diagnosis of heart failure and nephritic syndrome was made at the second admission. In addition, immunoelectrophoresis showed a monoclonal IgD (lambda) M protein and increased plasma cells in the bone marrow, suggesting a diagnosis of multiple myeloma. The patient was thus given dexamethasone (20 mg per day for 4 days) intravenously, but his symptoms did not improve. Two weeks later, the patient deteriorated further with congestive heart failure and renal failure, and subsequently died of cardiac arrest with ventricular fibrillation. On autopsy, IgD (lambda)-positive plasma cell proliferation was found in the bone marrow, confirming the diagnosis of multiple myeloma. In addition, amyloid deposition was detected in various organs including the heart, kidneys, esophagus, duodenum, ileum, colon, tongue, and lungs. In particular, the weight of the heart was 650 g demonstrating a hypertrophic septum and amyloid deposition in the myocardium and even coronary arteries. In summary, the final diagnosis was IgD (lambda) multiple myeloma associated with systemic amyloidosis.

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.

The aim of this study was to describe the occurrence of acute coronary syndromes in 3 cases of rituximab infusions. We reviewed the records of 3 patients with lymphoproliferative disorders who experienced acute coronary syndromes associated with their initial infusion of rituximab. All 3 patients received rituximab according to a standardized institutional rate schedule, and all received pre-medication with acetaminophen and diphenhydramine. The median age of patients was 61 years. One patient had known atherosclerotic heart disease, and 2 patients had risk factors for coronary artery disease. All patients had varying degrees of evidenced high tumor burden, including lymphocytosis, elevated lactate dehydrogenase values, bulky tumor masses, and bone marrow involvement by lymphoma. All 3 patients experienced fairly typical chest pain syndromes and experienced elevations of cardiac enzymes consistent with myocardial ischemia. One patient died of an arrhythmia that deteriorated into asystole, and 2 patients recovered and underwent coronary angiography. Acute coronary syndromes can be associated with the infusion of rituximab. Patients with a history of previous coronary artery disease or risk factors for coronary artery disease should be observed closely for signs of myocardial ischemia, particularly during the initial infusion. The occurrence of symptoms that could be ascribed to an acute coronary syndrome should always be taken seriously during the first rituximab infusion and investigated aggressively. Patients should be aware that this is a rare, albeit serious, complication of treatment with rituximab.

A 78-year-old man complained of right lateral chest pain. Chest X-ray showed an abnormal shadow in the right upper lung field and chest computed tomography (CT) scan showed a lateral chest wall tumor sorrouding the right 4th rib. Bone scintigraphy revealed only one lesion in the right 4th rib. Chest wall tumor resection was done. Histological analysis of the tumor specimen showed plasmacytoma. After the operation, the diagnosis of multiple myeloma was established by demonstration of myeloma by a bone marrow biopsy. Multiple myeloma should be taken into account as one of causes of a chest wall tumor even if it is a solitary tumor of the rib.

Chest pain is an extremely common presenting symptom that is usually related to a cardiac cause. This case illustrates an unusual presentation of multiple myeloma as a cause of atypical chest pain. This case presentation shows the importance of having a broad differential diagnosis while evaluating patients with atypical chest pain. It also illustrates the potential role of Tc-99m sestamibi imaging as a diagnostic modality in patients with multiple myeloma.

Multiple myeloma is a malignant proliferation of plasma cells that affects mainly bone marrow but may also involve other organs as well. We report thoracic involvement in the form of left-sided pleural effusion, osseous lesions, bronchial infiltration, and mediastinal lymphadenopathy in a 61-year-old woman, non-smoker presented with chest pain, dyspnoea, cough and deterioration in general health over the preceding seven months. Immunoelectrophoresis and immunofixation showed raised kappa-light chain immunoglobulin G (IgG) in serum and pleural fluid. Bronchial and pleural biopsies documented myelomatous infiltration and bone marrow aspirate revealed extensive plasma cell infiltration. At eight months, following the fourth cycle of melphalan, endoxan and prednisone based chemotherapy, the patient died.

A male, 62-year-old patient presented with chest pain with no apparent cause. Imaging studies revealed solution of continuity of the bone tissue at the level of the sternum, which led to paradoxical respiration. Open reduction and fixation with an LCP plate and screws were performed to address the problem. An important part of the patient's history was lumbar pain treated conservatively with analgesics and muscle relaxants. The pain did not subside and X-rays were done with findings of osteolysis in several parts of the body. The patient had chest pain and respiratory distress and was referred for management. Sternum fractures occur occasionally and are due to high-energy trauma or sports accidents. Treatment is conservative in most cases or may consist of a wire cerclage. Treatment was aimed at fixing the sternum to improve ventilatory mechanics so that the patient could continue with background therapy for multiple myeloma. At 18 weeks the patient is doing fine, X-rays show grade IV healing, and he will go on to the second stage of radiotherapy.
