From 1960 through 1972, 236 cases of amyloidosis with histologic proof were found. The amyloidosis was primary (without evidence of preceding or coexisting disease) in 132 cases (group 1) and associated with multiple myeloma in 61 (group 2). Secondary amyloidosis appeared in 19 cases (associated with rheumatoid arthritis or osteomyelitis in two-thirds of them). There were 22 patients with amyloid localized to a single organ (bladder, lung, skin, or larynx in more than half of them). Two patients had familial amyloidosis. In group 1 and group 2, the most common presenting symptoms were fatigue, weight loss, edema, dyspnea, light-headedness or syncope, and paresthesias. Symptoms of the carpal-tunnel syndrome were frequent. The liver was palpable in almost 50% of the series, but splenomegaly was an initial finding in less than 10%. Macroglossia was recorded in 26% of group 2 and in 12% of group 1. Enlargement of submandibular structures was noted in about 10% of cases; and purpura, particularly around the eyes, was a significant feature. Substantial numbers of the patients had carpal-tunnel syndrome, nephrotic syndrome, congestive heart failure, sprue, peripheral neuropathy, or orthostatic hypotension. Approximately 50% of patients had renal insufficiency at the time of diagnosis. Proteinuria was found in more than 90%. A monoclonal protein was found in the serum of 49% of group 1 and in 74% of group 2. Monoclonal proteins were found in the urine of 35% and 81%, respectively. Only 12% of patients in group 1 had no monoclonal protein when both serum and urine were analyzed, and all patients of group 2 had a monoclonal protein in the serum or urine when both were analyzed. Lambda light chains were more common than kappa. None of the patients in group 1 had more than 15% plasma cells in the marrow, whereas more than half of group 2 had more than 15% plasma cells. Roentgenograms showed no evidence of skeletal disease in 94% of group 1, but 50% of group 2 had skeletal abnormalities. Rectal biopsy was positive for amyloid in 84% of cases. Kidney, liver, and carpal-tunnel biopsies were positive in 90% or more. Follow-up of all 193 patients in groups 1 and 2 revealed that 80% of group 1 and 97% of group 2 had died. The median survival was 14.7 months in group 1 and 4 months in group 2. Cardiac failure was the most common cause of death, accounting for 30% of the fatalities. We also reclassified all cases by the method of Isobe and Osserman (105), which is based on clinical patterns: pattern I--principal involvement of tongue, heart, gastrointestinal tract, muscle, nerves, skin, and carpal ligaments; pattern II--principal involvement of liver, spleen, kidneys, and adrenals; and mixed pattern I and II. This analysis failed to reveal predictive value in the clinical pattern classification, and did not discern the survival differences between primary amyloidosis (group 1) and amyloidosis with myeloma (group 2). Consequently, for the present we prefer the classification used in this study.

We encountered a patient with multiple myeloma who died suddenly, in whom bilateral pulmonary artery thrombosis was found at autopsy. The patient was a 50-year-old woman who had received chemotherapy for multiple myeloma at a local clinic for 4 years, and was transferred to our hospital because of recurrence of multiple myeloma in August 1990. Despite chemotherapy performed after admission, serum globulin level increased and her low back pain worsened, and she was generally restricted to bed. On October 21, she developed sudden dyspnea, became markedly cyanotic, lost consciousness, and then suffered a cardiopulmonary arrest. Autopsy revealed bilateral pulmonary artery thrombosis as well as thrombosis in the pelvic veins. Hyperviscosity due to multiple myeloma and long-term recumbency were the probable causes of pelvic venous thrombosis and subsequent pulmonary artery thrombosis. We report a rare case of bilateral pulmonary artery thrombosis which developed during the course of multiple myeloma and led to sudden death.

A 65-year-old man, who had been treated for multiple myeloma (MM) since 1986, was admitted because of loss of consciousness in September 1989. An electrocardiogram taken just before admission showed a sinus arrest, junctional escaped rhythm, and marked bradycardia. The diagnosis of sick sinus syndrome (SSS) was made. Soon a temporary pacemaker was inserted, and the dyspnea ameliorated. However on the second day in the hospital, he had a high fever and Staphylococcus aureus was detected in the cultured blood. A diagnosis of septicemia was made, and the pacemaker was removed. He was then treated with beta-stimulants, but died in November 1989. Necropsy revealed cardiomegaly and microscopic examination showed amyloid deposits in the sinoatrial node, and the walls of the ventricles and coronary arteries. Although amyloidosis is often a complication of MM and the heart is frequently affected, SSS caused by amyloidosis associated with MM is quite unusual. In such patients, the use of a pacemaker is controversial, because amyloid deposits are occasionally accelerated by insertion of a pacemaker and for patients with hematological disorders, septicemia associated with pacemaker insertion may prove fatal.

Multiple myeloma of IgG kappa type was diagnosed in a 42-year-old man with bone pains, dyspnoea on exertion and increasing drowsiness. Six chemotherapy cycles extending over 14 weeks and consisting of 15 mg/m2 melphalan intravenously on day 1 and 60 mg/m2 prednisolone orally on days 1-4 produced a partial remission. As the HLA-identical sister of the patient was willing to donate bone marrow, an allogeneic marrow transplantation was planned. After 7 days' conditioning treatment (hyperfractionated whole-body irradiation with 12 Gy, chemotherapy with 70 mg/m2 melphalan and 60 mg/kg cyclophosphamide), 4.2 x 10(8) nucleated cells of donor marrow were infused per kg recipient body-weight through a central venous catheter. Despite prophylaxis with short-course methotrexate and cyclosporin, an acute graft-versus-host reaction of grade II-III occurred on day 26, though it settled almost completely after treatment with daily 2 mg/kg prednisone and monoclonal interleukin-2 receptor antibodies (B-B10, daily 10 mg). On day 100 after the marrow transplantation, marrow puncture showed the picture of complete remission with normal regeneration of haemopoietic cells. Allogeneic marrow transplantation may therefore be considered as a new and promising mode of treatment for younger patients with multiple myelomas.

Ten patients with severe hematologic malignancies (four with acute leukemia, three with multiple myeloma, one with prolymphocytic leukemia, one with malignant lymphoma and one with blastic crisis of chronic myelogenous leukemia) developed respiratory failure during the period between April 1986 and May 1990. Clinically, the patients manifested high-fever, dyspnea refractory to oxygen therapy, diffuse pulmonary rales and severe hypoxemia without evidence of cardiogenic pulmonary edema. Chest roentgenograms displayed diffuse alveolar infiltrates. Respiratory failure occurred as early as 48 hours and as late as 66 days after the administration of intensive anti-neoplastic chemotherapy. At that time leukocyte count was between 100/microliters and 54,900/microliters. Marked leukocytosis was observed in two patients with AML and PLL. Respiratory failure was preceded by sepsis in one patient with AML and by pneumonia in nine patients. DIC was diagnosed in four patients. All patients treated with high dose methyl prednisolone (mPSL) within 12 hours after the onset of respiratory failure. Only one patient required assisted ventilation. High dose mPSL had significant effect on seven of ten patients. But three patients died from progressive respiratory failure, sepsis, pneumonia and multi-organ failure.

A 60-year-old man presenting with cough, dyspnea and chest pain was found to have plasma cell myeloma with pulmonary involvement. Cytologic smears of a bronchial washing showed clusters and sheets of cells with vague plasmacytoid features. Prominent nucleoli, which were present in most of the cells, and occasional glandlike patterns suggested an adenocarcinoma, thus causing a differential diagnostic problem.

We present two cases of extramedullary plasmacytoma presenting as a mediastinal mass and preceding the onset of full-blown multiple myeloma. The patients are a 62-year-old woman who presented with progressive dyspnea and left-sided chest pain and a 59-year-old asymptomatic man. In both patients, radiographic studies revealed a posterior and anterior mediastinal mass, respectively. Surgical resection of the tumor was performed in the two cases. The tumors were characterized by a well-circumscribed proliferation of plasma cells surrounded by residual lymph nodal tissue. Immunohistochemical studies on paraffin sections demonstrated lambda light chain restriction. Follow-up in our patients revealed that both of them developed multiple myeloma after 6 months and 2 years, respectively. One patient received treatment with melphalan and prednisone and is currently alive and well without evidence of disease, 2 years after diagnosis. The second patient died 4 years after resection of his tumor with evidence of disease in lumbar spine, skull, and lungs. Extramedullary plasmacytoma presenting as a mediastinal mass may precede the onset of full-blown multiple myeloma; therefore, institution of early systemic therapy in these patients may be of value in preventing further progression of the disease.

There are two aspects to considerations of the value of peritoneal dialysis (PD) in the treatment of renal insufficiency with associated pathology. The first involves the effects of the treatment on the symptoms or evolution of the pathology. Examples include the improvement of dyspnea due to cardiac insufficiency (CI) and of cirrhotic ascites (CA). However, there is also an undefined risk of reactivation lupus. The second facet is the increased risk of peritoneal infection, particularly for patients who are HIV + or who are immunosuppressed due to lupus or myeloma. In certain types of case (lupus with intractable vascular thrombosis, intolerance of ultrafiltration in cases of CI, AC or generalised amyloidosis) PD has particular advantages. Nevertheless, there has been no appropriate prospective study to demonstrate or otherwise the advantages in terms of survival. The use of PD remains therefore a matter of choice for individual patients and experienced health care team.

The case of a 30-year-old man with primary systemic amyloidosis is reported. Three months prior to admission the patient developed fever, night sweats, dyspnea, and bilateral ankle swelling. Recurrent left-sided pleural effusion led to further investigation when massive proteinuria with free monoclonal lambda chains in the urine became evident. Abdominal subcutaneous fat aspiration and renal biopsy confirmed the diagnosis of amyloidosis. Bone marrow biopsy and bone scan did not reveal multiple myeloma. Echocardiography showed a sparkling texture of the interventricular septum. Pulsed-wave Doppler recording of the left ventricular inflow profile showed the pattern of advanced cardiac amyloidosis consistent with markedly impaired diastolic heart function. Electrocardiogram-gated magnetic resonance imaging was carried out for noninvasive evaluation of cardiac function. The patient was started on repeated courses of melphalan, prednisone, and colchicine therapy. Despite increasing deterioration of renal function the therapy was tolerated quite well, and the patient is still alive 10 months after initial diagnosis. Although very rare in this age, primary systemic amyloidosis should be considered as a cause of pleural effusion, proteinuria, and congestive heart failure and should lead to further investigation.

The authors report the case of a 36-year-old male who, following investigations for dyspnea, othopnea and peripheral cyanosis, was found to have metastatic intracardiac plasmacytoma. Diagnosis was made initially with transesophageal echocardiography and emergent cardiac surgery was performed. Postoperative transthoracic and transesophageal echocardiograms revealed residual masses in the right and left atrium. The patient was subsequently treated with systemic chemotherapy and was symptom-free within three months of treatment, with rapid decline of paraproteins in the serum and urine. This case of intracardiac metastatic plasmacytoma is deemed unique because cardiac involvement with multiple myeloma has not been studied in detail, largely due to the rarity of such a presentation.
