Primary cardiac lymphoma (PCL) is a rare presentation of lymphoma in children. The emergency nature of its presentation (heart failure and arrhythmias) makes management of this entity difficult. The authors describe two children with lymphoma primarily involving the heart; one patient was a case of PCL and the other was a case of lymphoma involving the heart along with pelvic involvement. These two patients, together with a literature review on the topic, suggest that if the diagnosis of PCL is made early and treatment is expeditiously started, patients may do well.

Clinical trials have shown the anti-tumor necrosis factor-a (TNF-a) drugs to be safe and efficacious for the treatment of rheumatoid arthritis (RA). However, since their release for general use, reports have raised concerns about potentially serious complications including tuberculosis, lymphoma, and cardiac failure. It must be remembered that patients with RA are already at increased risk of many of these complications,due both to their underlying inflammatory disease activity and the immunosuppressing effects of many conventional disease modifying antirheumatic drugs. It is unknown whether anti-TNF-a therapies are putting patients at increased risk of adverse events above what might already be expected. Data on the frequency of these adverse events have come predominantly from 3 sources: followup of subjects recruited to clinical trials, spontaneous adverse event reporting to national pharmacovigilance systems, and surveillance of patients treated in routine practice. Each of these study designs plays an important role in assessment of new drugs. However, each also has limitations, which must be considered when interpreting adverse event rates.

An unusual case of primary cardiac lymphoma presenting as restrictive cardiomyopathy with arrhythmia is reported in a 72-year-old woman who was admitted for evaluation of exertional dyspnea and palpitations. Electrocardiography (ECG) showed atrioventricular dissociation and right heart cardiac catheterization revealed a typical 'dip-and-plateau' waveform. Restrictive cardiomyopathy was suspected because computed tomography (CT) did not reveal pericardial thickening, calcifications, or an effusion. Heart failure initially improved with diuretic therapy, but subsequently worsened, and the patient experienced a syncopal episode. ECG showed atrial fibrillation, and CT revealed a large mass in the right atrium and multiple tumors in the liver, which needle biopsy confirmed as diffuse large B-cell lymphoma. Chemotherapy induced complete remission, and her heart failure markedly improved. The 'dip-and-plateau' waveform was no longer detected on repeat cardiac catheterization and the ECG showed restoration of sinus rhythm. Clinically, the diagnosis was primary cardiac lymphoma.

Over the last decade, several new drugs have become available for the treatment of patients with rheumatoid arthritis. These agents include the new disease-modifying antirheumatic drug (DMARD) leflunomide and the biologic agents, tumor necrosis factor (TNF)-alpha antagonists and an interleukin (IL)-1 receptor antagonist. Methotrexate is commonly used as the first DMARD, has a well documented clinical efficacy and slows radiological deterioration. Sulfasalazine appears to have similar properties, albeit to a lesser extent. Leflunomide has similar efficacy as methotrexate but it is less tolerated than sulfasalazine. The adverse effect profiles of these three drugs makes regular laboratory monitoring mandatory. Several combination therapies with DMARDs were proven to be more effective than mono-DMARD therapy. However, until now these strategies have not been widely adopted. TNF antagonists are potent anti-inflammatory drugs, with a rapid onset of effects compared with traditional DMARDs. The IL-1 receptor antagonist, anakinra, has an intermediate place between methotrexate and the TNF antagonists with respect to efficacy. The adverse effects of TNF antagonists include an increased incidence of common and opportunistic infections. Thus far, anakinra has not been associated with an enhanced rate of opportunistic infections. Some of the biologic agents have been associated with worsening heart failure and demyelinating disease. The limited long-term safety data of the biologic agents are a point of concern because, at present, an enhanced risk for malignancies, particularly lymphoma, can not be excluded. Drug costs of traditional DMARDs are up to US dollars 3000 per year, whereas for the biologics the yearly drug costs range between US dollars 16,000 and > US dollars 20,000. Cost-effectiveness analyses are necessary to determine whether or not these high costs are justified. Unfortunately, adequate, prospective, economic evaluations are not yet available. Until these become available, treatment decisions will be based on the balance of direct costs and indirect costs and expected cost savings in the future.

As cardiac involvement by malignant lymphoma (ML) is relatively uncommon and antemortem diagnosis is difficult, details of this condition remain to be elucidated. To clarify clinicopathologic features of cardiac lymphoma (CL), 25 autopsy cases were studied. Each was rediagnosed according to the World Health Organization (WHO) classification, and clinicopathologic characteristics were investigated by tumor phenotype. The study subjects were 13 males and 12 females with a mean age of 53.4 years. All cases were secondary CL and were not diagnosed as CL before death; 14 cases (56%) were of B-cell and 11 (44%) of T-cell (including natural killer cell) phenotype. Nasal and nasal-type natural killer/T-cell lymphomas (NKTLs) accounted for five (20%). Cardiac manifestation was evident in eight (32%), with hematogenous infiltration as the most common pattern of tumor spread. Some B-cell CLs (n=3) were complicated by cardiac tamponade and heart failure (HF), and T-cell CLs (n=5), including three nasal NKTLs, also featured arrhythmia and sudden death. The incidence of T-cell phenotype was significantly elevated for CLs (p<0.05), especially for CLs with cardiac manifestation (p<0.01), compared with that for MLs in general. Our results indicate that T-cell lymphomas, compared with B-cell lymphomas, invade the heart more frequently and aggressively and are associated with a variety of cardiac manifestations. Where cardiac involvement is suspected, aggressive diagnostic procedures are warranted, especially with MLs having a T-cell phenotype. In cases of nasal NKTL, particular attention is necessary.

Posttransplantation lymphoproliferative disorders (PTLD) presenting clinically in the skin are rare and usually of B-cell phenotype. Only 7 cases of cutaneous T-cell PTLD have been previously reported, mostly mycosis fungoides type, with no known cases of "cutaneous" presentation by CD30 (Ki-1) anaplastic large cell lymphoma (ALCL). The case reported is a 59-year-old male who developed multiple skin nodules on the right leg, 6 years following renal transplantation. Initial biopsy showed ALCL involving the dermis with a background rich in neutrophils. The neoplastic cells were of T-cell phenotype, strongly CD30 with typical staining, and BCL-2 positive, but P53 negative. No EBV was detected by IHC, ISH, or DNA analysis. One year later, he developed painful subcutaneous nodules with surrounding erythema, resembling deep pustules or panniculitis, which on biopsy showed preferential involvement of the subcutaneous fat and prominent component of neutrophils. Twenty-two months following diagnosis, he died of cardiac failure with terminal myocardial infarct. There was however no clinical evidence of systemic spread of the lymphoma.This report adds to the clinical and morphologic spectrum of these rare "cutaneous" lymphomas of T-cell lineage arising in the posttransplantation setting, and suggests that EBV does not play a role in their pathogenesis.

We report an instructive case of diffuse large B-cell lymphoma presenting as acute heart failure. A 69-year-old human immunodeficiency virus-negative man was admitted to our hospital for general fatigue. A computed tomographic scan of the chest and abdomen showed pericardial effusion, but there was no evidence of tumor masses, lymph node enlargement, or hepatosplenomegaly. During the chemotherapy, increased lactate dehydrogenase and pleural effusion appeared. The tumor cells in the effusion showed positivity for CD5, CD19, CD20, kappa chain, and Bcl-2 and negativity for CD10 and CD23. The chromosomes showed t(8;14)(q24;q32) with c-myc/immunoglobulin (Ig)H rearrangement, and the MIB-1 index was not high (60%). Neither human herpes virus 8 nor Epstein-Barr virus DNA was detected in the cells by polymerase chain reaction. The response to chemotherapy was very poor, and the patient died 4 months after the diagnosis. A spectrum of the symptoms of CD5+ lymphoma encompasses pericardial effusion and also can accompany c-myc/IgH rearrangement.

Eighteen liver transplant recipients were followed up for 10 years after a trial of immunosuppression withdrawal. Three groups were identified according to the early outcome of complete (group A, n = 5), partial (group B, n = 9), and unsuccessful (group C, n = 4) withdrawal of immunosuppression. The indications for liver transplantation (LT) (August 1983-December 1988) were as follows: primary biliary cirrhosis (n = 3), primary sclerosing cholangitis (n = 3), Budd-Chiari syndrome (n = 3), acute liver failure (n = 3), hepatitis C virus (HCV) cirrhosis (n = 1), HCV and autoimmune hepatitis (n = 1), HCV and alcohol-related cirrhosis (n = 1), HCV and hepatocellular carcinoma (HCC) (n = 1), cystic fibrosis (n = 1), and liver metastases from testicular teratoma (n = 1). Immunosuppression was based on cyclosporine. All patients experienced 1 or more complications of prolonged immunosuppression (median, 7 years; range, 5-11). Thirteen patients (72%) are alive at a median interval of 17 years (range, 16-21) after LT. Of the 5 patients in group A, 2 currently have normal graft function with no rejection episodes, and 3 have restarted immunosuppression following late low-grade acute rejection (n = 1), retransplantation for chronic rejection (n = 1), and kidney transplantation (n = 1). Of the 9 patients in group B, 5 died. The deaths were due to ruptured arterial pseudoaneurysm following retransplantation, HCC recurrence, cardiac failure, renal failure, and posttransplant lymphoma at 5, 7, 7, 14, and 17 years after LT, respectively. All 4 patients in group C are alive on a full immunosuppressive regimen. Long-term follow-up of 18 LT recipients withdrawn from immunosuppression has shown that at a median of 17 years 10% of patients remain off all immunosuppression.

Primary cardiac lymphoma is an extremely rare extranodal non-Hodgkin's lymphoma, exclusively located in the heart and/or the pericardium with no evidence of extracardiac dissemination. In this report, we describe a cardiac B-cell lymphoma arising in a 70-year-old woman who presented to the hospital with heart failure symptoms and a high-degree atrioventricular block of unknown origin. Echocardiography revealed a massive infiltrative thickening of the atrial septum, the aortic root, and the pericardium. Pulsed wave and Doppler tissue findings were highly suggestive for pericarditis constrictiva. Positron emission tomography showed unusually strong metabolic activity in the atrial septum, both atria, and the entire pericardium. Suggested malignoma was confirmed by the pericardial biopsy specimens, which revealed a high-grade diffuse CD20+ B-cell lymphoma.

Doxorubicin-induced cardiomyopathy is not uncommon and may progress to end-stage heart failure. Treatment of this condition with heart transplantation, however, requires that the primary malignancy be deemed "cured." We present the case of a 55- year-old woman who had doxorubicin-induced cardiomyopathy and non-Hodgkin's lymphoma. The active status of her lymphoma precluded heart transplantation. She had end-stage heart failure and underwent the insertion of a left ventricular assist device as a destination therapy.
