Abstract
Primary gastric diffuse large B-cell lymphomas are generally well controlled by non-surgical treatment with combination chemotherapy followed by radiotherapy. We have previously reported that over 90% of patients achieved complete response (CR) with this therapeutic strategy: three cycles of cyclophosphamide, adriamycin, vincristine and prednisone followed by radiotherapy (40.5 Gy). Although the CR rate was very high, some patients still showed resistance to this combination therapy. In order to clarify the factors related to therapy resistance, we examined the relationship between Epstein-Barr virus (EBV), which was examined using an in situ hybridization technique, and the patients' clinical courses. Out of the 50 patients, four were EBV positive; over half of lymphoma cells were positive for EBV by in situ hybridization. Of the three EBV-positive patients, two showed progressive disease and one achieved partial response (PR). Two of the patients died of disease progression. The other patient achieved CR, but the lymphoma recurred with distant metastasis in the cerebellum 3 months after remission. In the present study, eight patients did not achieve CR or they relapsed, four patients showed progressive disease, one patient achieved PR, and three patients achieved CR with recurrence. Therefore, half of these unfavorable patients were EBV positive. This finding strongly indicated that EBV-associated gastric diffuse large B-cell lymphomas frequently show resistance to standard chemoradiotherapy, although some other adverse factors remain unclear.

Abstract
Although cytogenetic analysis advanced the understanding of the pathogenesis of primary non-Hodgkin lymphoma and led to improved clinical management, there have been no large cytogenetic studies of post-transplant lymphoproliferative disorder (PTLD). We examined the karyotypes of 36 PTLD cases and correlated them with clinical, laboratory, and pathologic findings. The cases included 2 early lesions, 13 polymorphic PTLDs, and 21 monomorphic PTLDs (18 B-cell and 3 T-cell proliferations). Cytogenetic abnormalities were identified in 72% of monomorphic B-cell PTLDs and in all T-cell PTLDs, but in only 15% of polymorphic PTLDs and in no early lesions. The most frequent clonal abnormalities in monomorphic PTLD were trisomies 9 and/or 11 (5 cases), followed by rearrangements of 8q24.1 (4 cases), 3q27 (2 cases), and 14q32 (2 cases). MYC rearrangement (8q24.1) and T-cell-associated chromosomal abnormalities correlated with poor outcome and short survival. PTLD with trisomy 9 and/or 11 developed early after transplant, presenting as Epstein-Barr virus-positive large B-cell lymphoma with prolonged survival.

Abstract
HIV-associated Primary brain lymphomas (PBLs) are usually diffuse, large B-cell lymphomas (DLBCLs). In contrast to those occurring in immunocompetent patients, nearly all HIV-associated PBLs are associated with Epstein-Barr virus (EBV). Since viral latency proteins are target antigens for anti-viral cytotoxic T lymphocytes, the double immunodeficiency (HIV infection, central nervous system microenvironment) favors the expression of viral latency proteins (LMP-1, EBNA2). These proteins play a major role in immortalization and transformation of infected B lymphocytes through cell cycle activation and apoptosis inhibition.

Abstract
PURPOSE Epidemiologic studies show an association between hepatitis C virus (HCV) and B-cell non-Hodgkin's lymphoma (NHL). Treatment and outcome of patients with diffuse large-cell lymphoma (DLCL) and HCV infection are still a matter of debate. PATIENTS AND METHODS We studied the HCV-positive patients with B-cell DLCL included in the Groupe d'Etude des Lymphomes de l'Adulte (GELA) programs LNH 93 and LNH 98. They were compared with the other patients with DLCL included in these programs. HCV infection prevalence was 0.5% (26 of 5,586 patients). RESULTS Histologic types of HCV-positive DLCL were more frequently transformed from low-grade lymphoma than DLCL in HCV-negative patients (32% v 6%, P = .02). This is also supported by more frequent spleen involvement in HCV-positive patients (46% v 17%, P < .001). HCV-positive patients had more frequently elevated lactate dehydrogenase levels than other patients (77% v 55%, P = .02). Outcome of HCV-positive patients was poorer for overall survival (P = .02) but not for event-free survival (P = .13). After matching on age and prognosis factors, at 2 years of follow-up, the overall survival was 56% (95% CI, 33% to 76%) among HCV-positive patients, versus 80% (70% to 89%), and the event-free survival was 53% (33% to 72%) versus 74% (64% to 84%). The short-term hepatic toxicity of chemotherapy was strongly increased among HCV-positive patients. After exclusion of the two subjects with chronic hepatitis B virus infection, the overall proportion of subjects undergoing hepatic toxicity was 65% (15 of 23 patients). CONCLUSION HCV-positive patients with DLCL differ from other patients both at presentation and during chemotherapy. Specific protocols evaluating antiviral therapy should be designed for these patients.

Abstract
Infection with human immunodeficiency virus (HIV) increases the risk of developing non-Hodgkin lymphoma. Plasmablastic lymphoma (PBL) is a rare variant of diffuse large cell lymphoma that often involves the oral cavity of HIV+ patients. It is characterized by immunoblastic morphology and plasma cell phenotype. Cutaneous involvement in PBL appears to be rare. We report a 44-year-old man with AIDS and Kaposi sarcoma (KS) previously treated with doxorubicin who, following treatment with highly active antiretroviral therapy, developed an erythematous infiltrated nodule on the right arm. Histology showed subcutaneous fat necrosis and clusters of atypical large plasma cells (plasmablastic cells). Immunohistochemistry revealed lambda light chain restriction. Epstein-Barr virus (EBV) mRNA was detected by in situ hybridization within the plasmablastic cells. Polymerase chain reaction amplification with specific primers for human herpesvirus 8 (HHV-8) performed on the skin biopsy specimen detected a specific band. A complete screening (bone marrow biopsy, computed tomographic scan, radiological survey) disclosed no abnormalities. The lesion resolved spontaneously after 3 months. Two years later an infiltrated plaque developed on the abdominal wall. The clinical and histopathological features of this new lesion were similar to those observed 2 years previously. No evidence of extracutaneous involvement was detected. The lesion again resolved spontaneously after 25 days. PBL may be seen in patients with transplants or receiving chemotherapy, but is usually observed in patients with advanced AIDS. The observation of recurrent self-healing EBV- and HHV-8-associated cutaneous monoclonal plasmablastic infiltrates, in a patient with AIDS and KS, expands the clinical spectrum of AIDS-associated plasmablastic lymphoproliferative disorders.

Abstract
BACKGROUND Kaposi sarcoma associated herpesvirus (KSHV)/human herpesvirus 8 (HHV-8) associated lymphomas, which often develop in human immunodeficiency virus (HIV) infected patients with advanced AIDS, present predominantly as primary effusion lymphoma (PEL) or, less frequently, as "solid" extracavitary based lymphomas, associated with serous effusions. These last lymphomas, also called "solid PEL", have been reported before the development of an effusion lymphoma and after resolution of PEL. Interestingly, KSHV/HHV-8 associated lymphomas that present as solid or extracavitary based lesions in HIV seropositive patients without serous effusions have been reported recently. METHODS/RESULTS This paper provides evidence for the existence of a previously undescribed KSHV/HHV-8 associated lymphoma in HIV seronegative patients without serous effusions. These lymphomas exhibit a predilection for the lymph nodes and display anaplastic large cell morphology. These tumours were completely devoid of common cell type specific antigens, including epithelial and melanocytic cell markers. B and T cell associated antigens and other commonly used lymphoid markers were absent or weakly demonstrable in a fraction of the tumour cells. Conversely, immunohistochemical studies showed strong immunostaining with plasma cell reactive antibodies. CONCLUSIONS Analysis of viral infection and immunohistological studies are of primary importance to define this lymph node based KSHV/HHV-8 associated lymphoma with anaplastic large cell morphology and plasmablastic immunophenotype occurring in HIV seronegative patients without serous effusions.

Abstract
Hepatitis virus infection, especially type C (hepatitis C virus [HCV]), has been suggested to be one of the important pathogenetic factors for low- and high-grade B-cell lymphoma, including splenic marginal zone lymphoma (SMZL), in southern Europe. Here, we analyzed the incidences of HCV and hepatitis B virus (HBV) infections, and the clinicopathologic features in 29 cases of splenic diffuse large B-cell lymphoma (DLBCL), 10 SMZL, 3 splenic mantle cell lymphoma, 1 hairy cell leukemia, 13 B-chronic lymphocytic leukemia, and 12 hepatosplenic T-cell and natural killer cell lymphoma. Fifteen (51.7%) splenic DLBCL cases were HCV antibody-positive, and another 6 (20.7%) had the HBsAg. The incidence of each was significantly (P < .01) higher than those of HCV (9.3%) and HBV (1.9%) infections in 54 node-based DLBCL cases. Four examined HCV-positive DLBCL cases showed no type II cryoglobulinemia. HCV RNA was detected in fresh tumor tissues from 6 of 7 examined DLBCL cases, and HBV DNA was present in another 2, as evaluated by real-time polymerase chain reaction. Immunohistologically, tumor cells in 5 of 7 examined DLBCL cases showed intracytoplasmic reactions for HCV NS3 and E2 proteins and the viral receptor CD81. Of 6 cases, 2 showed an intranuclear reaction for the HBV surface protein. By Southern blot analysis, no rearrangement of the Bcl2 gene was detected in the tumor tissue of 7 HCV-positive DLBCL cases. For the other types of malignant lymphoma, 1 case each of SMZL (10%) and hepatosplenic T-cell and natural killer cell lymphoma (8.3%) showed HCV infection. In conclusion, persistent human hepatitis virus infections, especially HCV, may play an important role in the tumorigenesis of splenic DLBCL in Japan.

Abstract
A 57-year-old man was admitted to hospital because of motor aphasia on 16 September 2000. He had an approximate 2-year history of haemodialysis treatment, since April 1997, and had received a cadaveric renal transplantation in July 1999. Computed tomography and magnetic resonance imaging (MRI) revealed a mass with ringed enhancement in the left temporal-parietal lobe. Primary central nervous system (CNS) lymphoma (diffuse large B cell type) was diagnosed based on an open brain tumour biopsy. Epstein-Barr virus early RNA (EBER) in situ hybridization showed positive signals in the nuclei of the CNS lymphoma cells. A dose reduction of immunosuppressant and three series of high-dose methotrexate (MTX) therapy with leucovorine rescue followed by irradiation (whole brain irradiation, 30 Gy; partial brain tumour irradiation, 20 Gy) were carried out for his primary CNS lymphoma. The patient is currently in good condition (September 2004) with no enlargement of the lymphoma, as examined by MRI every 3 months, and preserved renal function.

Abstract
Kaposi sarcoma-associated herpesvirus (KSHV) is known to be associated with two distinct lymphoproliferative disorders: primary effusion lymphoma (PEL) and multicentric Castleman disease (MCD)/MCD-associated plasmablastic lymphoma. We here report a high incidence of KSHV infection in solid HIV-associated immunoblastic/plasmablastic non-Hodgkin's lymphomas (NHLs), in patients lacking effusions and without evidence of (prior) MCD. Within a cohort of 99 HIV-related NHLs, 10 cases were found to be KSHV positive on the basis of immunostaining for KSHV LNA-1 as well as KSHV-specific polymerase chain reaction. All but one of the tumors coexpressed Epstein-Barr virus. Interestingly, all KSHV-positive cases belonged to a distinctive subgroup of 26 diffuse large B-cell lymphomas characterized by the expression of CD138 (syndecan-1) and plasmablastic/immunoblastic morphology. These KSHV-positive lymphomas were preceded by Kaposi sarcoma in 60% of the patients and involved the gastrointestinal tract in 80%. Our results indicate that KSHV infection is not restricted to PEL and MCD; it is also common (38%) in HIV-related solid immunoblastic/plasmablastic lymphomas.

Abstract
Anaplastic large cell lymphoma (ALCL), CD30+, is a subtype of T-non-Hodgkin's lymphoma (NHL). Its most common form is a classical systemic type that involves multiple nodal and extranodal sites. In this study, morphologic, immunohistologic, and genetic studies were performed on ALCL cases in Pakistani patients. The median age of the patients in this study was 45 years (age range: 5-70 years), with a male to female ratio of 3.4:1. Thirty-seven (37) patients were diagnosed to have Ki-1 (CD30+) ALCL, which constituted 2% of all NHLs and 12.6% of all T-NHLs, over a period of 11 years (January 01, 1992-December 31, 2002). The tumors were of either T- or null-cell type with constant (100%) expression of CD30 (Ki-1). The majority of the cases (89.2%) expressed EMA, whereas 40.5% of the cases expressed either CD45 (LCA), CD45RO (UCHL1), or ALK. The mean age of ALCL patients with null-cell phenotype was 33.8 years as compared to those with T-cell phenotype having a mean age of 36.3 years. Out of the 37 cases diagnosed as ALCL, amplifiable DNA was isolated from 28 cases, which were further assessed for T-cell clonality for T-cell receptor (TCR)-beta, gamma, and immunoglobulin heavy chain (IgH) for the FR2 and FR3 regions. The polymerase chain reaction (PCR) technique demonstrated clonal rearrangement of the TCR beta, gamma, and IgH regions in 15 (53.6%), 11 (39.3%), and 2 (7.1%) ALCL cases, respectively, out of 28 cases. Association of Epstein-Barr virus (EBV) was noted in seven out of 28 cases (25%) of ALCL by PCR, whereas ISH for EBV-encoded nuclear RNA-1 (EBER-1) detected the presence of EBV in two (16.7%) out of 12 cases, where one was T-cell ALCL and the other null-cell ALCL. Immunostaining for LMP-1 could not be performed, because tissue material was not available. In conclusion, our study demonstrated that the prevalence of ALCL in Pakistan is comparable to that reported for some of the Asian communities and by the International Lymphoma Study Group and that EBV could be partly responsible for the pathogenesis of ALCL.

Abstract
Primary hepatic lymphoma is a rare but well-defined lymphoma entity that often pursues an aggressive clinical course. Most cases have been described in hepatitis C virus (HCV)-related chronic liver disease patients. Although anthracycline-based chemotherapy has been reported to be highly effective, the best therapeutic strategy has not been defined yet. The prognosis is dismal especially in patients treated with chemotherapy alone or when an advanced liver disease is present. Herein, we describe a case of primary hepatic large B-cell non-Hodgkin's lymphoma, in a patient with HCV chronic infection. After a minor response with eight cycles of CHOP chemotherapy, a complete and sustained remission was obtained with alpha-interferon at the daily dose of 3 MU. HCV-RNA clearance pace from the blood almost paralleled the response of the lymphoma and both diseases went in remission within 1 year of therapy. The possible place of alpha-Interferon in the treatment of primary hepatic lymphoma is discussed.

Abstract
Epstein-Barr virus (EBV) latently infects and immortalizes B lymphocytes and causes lymphoproliferative malignancies. We show here that the EBV nuclear antigen EBNA2 induces expression of the 2 chains of the interleukin-18 receptor (IL-18R) in Burkitt lymphoma (BL) cell lines and in nontransformed B cells. Activation of IL-18R expression by EBNA2 is independent of its interaction with the transcriptional repressor RBPJ kappa. It occurs in the absence of any other viral protein but requires de novo synthesis of cellular proteins. IL-18R induction is a highly specific function of EBNA2, because neither other EBV latent proteins nor the cellular proteins c-myc or Notch can exert this effect. Using cDNA microarray expression profiling, we find that the IL-18 receptor expressed in EBV-infected BL cells has signaling capacity, because IL-18 significantly modified gene expression. We report that EBNA2 expression is associated with IL-18R expression in vivo in EBV-positive B-lymphomas from AIDS patients.

Abstract
BACKGROUND Plasmablastic lymphoma (PBL) is a recently recognized entity most often reported in the oral cavity, mainly in the setting of underlying human immunodeficiency viral infection whereby a role for Epstein-Barr virus (EBV) and more recently human herpesvirus 8 (HHV8) has been described. Although EBV has been implicated in a variety of lymphoproliferative lesions, until recently HHV8 has only been associated with primary effusion lymphoma, multicentric Castleman's disease, and Kaposi's sarcoma. We describe a case of PBL occurring in the setting of renal transplantation. METHODS We encountered a case of PBL occurring in the setting of renal transplantation. We characterized the tumor by routine immunohistochemistry and evaluated for the presence of immunoglobulin light chain restriction and EBV RNA by in situ hybridization. We assessed for the presence of HHV8 RNA by reverse transcriptase in situ hybridization. RESULTS The tumor showed a histomorphology compatible with a PBL. In addition, there was strong RNA expression in the neoplastic cells for EBER-1, EBER-2, and HHV8. CONCLUSION This case suggests a possible role of both viruses in the pathogenesis of PBL in sites other than the oral cavity and expands the spectrum of post-transplantation lymphoproliferative disease to include PBL.

Abstract
We describe the case of a patient treated with 2-chloro-2'-deoxyadenosine, CdA or Cladribine for hairy cell leukemia who subsequently developed an Epstein Barr virus (EBV)-positive polymorphous large B-cell lymphoma (p-LBCL). The time interval between Cladribine therapy and development of p-BCL was 11 months and morphologically resembled an EBV-positive post transplant lymphoproliferative disorder (PTLD). Molecular genetic studies for EBV-clonality by Southern blot hybridization showed a clonal population of infected cells, implying that this was an EBV induced lesion. The chronology of events suggest that Cladribine, a purine analog which has been previously described to induce long-lasting immunodeficiency, can, in some cases, weaken the host defense mechanism to a level at which an innocuous EBV infection may transform the normal lymphoid cells into an aggressive neoplasm. Unlike most methotrexate-related lymphoproliferative disorders (LPDs), which undergo spontaneous remission after discontinuation of therapy, LPDs secondary to purine analogs often fails to resolve after discontinuation of therapy and requires additional therapy. Our patient was treated with rituximab following the diagnosis of p-LBCL, with the goal of improving the pancytopenia to permit chemotherapy. However, the patient failed to show any dramatic improvements in counts, developed systemic symptoms and progressive ascites. He expired 3 weeks after a second dose of rituximab. Cladribine is a potent immunosuppressive agent and should be included with the list of immunosuppressive agents that may be associated with EBV-related B-cell lymphoproliferative disorders.

Abstract
BACKGROUND Primary non-Hodgkin lymphoma (NHL) of the vagina is a rare location. Its association with the Epstein-Barr virus (EBV) has been only reported in another case. We present a new case, emphasizing the oncogenetic relevance of EBV. CASE REPORT A 45-year-old woman with a pelvic pain revealed in her vaginal inspection a thick and hard vaginal plug with a "paving stone" appearance. The biopsy reported a vaginal non-Hodgkin lymphoma type B of intermediate cell, with positive result for EBV. After treatment, a complete remission was obtained. CONCLUSION The EBV is the main responsible for the non-Hodgkin lymphoma; classified as a group I carcinogen, it has been associated with a variety of neoplastic tumors, although it is unusual with extranodal type B diffuse lymphoma.

Abstract
Epstein-Barr virus (EBV)-related herpesvirus (Si-IIA-EBV) was serially transmitted for 3 passages from rabbit to rabbit of the opposite sex by blood transfusion, which subsequently induced virus-associated rabbit lymphomas. The virus could be transmitted by transfusion with 15-20 ml of whole blood (7/7) or irradiated blood (1/6) from the EBV-related virus-infected rabbits, but there was no transmission with transfusion of cell-free plasma (0/6) from the infected rabbits. Passive anti-EBV-VCA IgG (x 20 approximately x 10) titers decreased during the first 1-2 weeks in the transfused rabbits. The virus-transmitted rabbits showed a gradual increase in antibody titers ranging from peak titers of x 640 to x 2560 after 3 weeks of transfusion. The recipient origin of malignant lymphoma that developed in the first rabbit transfused by infected blood was confirmed by chromosomal analysis. This rabbit model thus shows that EBV-related herpesvirus is serially transmissible by blood transfusion and that transmission can not be completely prevented by irradiation of blood, but removal of blood cells is the best way to prevent transmission of EBV-related virus. Therefore, this animal model provides a convenient in vivo system for studies of the prevention and therapy of transfusion-related transmission of EBV and EBV-associated lymphoproliferative diseases in immunocompromised human beings.

Abstract
Patients with HIV infection are at increased risk for B-cell neoplasms and plasma cell dyscrasias. Both B cell and plasma cell tumors tend to be intermediate or high grade and are frequently associated with Epstein-Barr virus. Patients with HIV infection are also at higher risk of acquiring plasmablastic lymphoma. Until this time, only sinus, oral gastrointestinal, and lung manifestation have been noted. In this report we describe a 41-year-old male with HIV infection who developed multiple pleomorphic, extramedullary plasmablastic lymphomas associated with Epstein-Barr virus. We review the clinical and immunological features of his malignancy and thereby expand the spectrum of disease to include additional sites (bones, testicles) not previously reported.

Abstract
INTRODUCTION Primary liver non-Hodgkin's lymphoma, are extremely rare in HIV-infected patient. Most of them are diffuse large-cell lymphoma with B cell type. EXEGESIS We report here the case of a 34-year-old HIV-infected patient, admitted for jaundice and fever since 15 days. Abdominal computerised tomography showed numerous hypodense lesions on all liver segments. The various biological, microbiological and morphological examinations (ultrasound, MRI with intravenous contrast agent specific for the liver) initially suggested a tumoral origin. The liver biopsy concluded to a large B-cell lymphoma. A chemotherapy (CHOP) with anti-CD20 monoclonal antibody (rituximab) was initiated without discontinuing antiretroviral therapy. CONCLUSION This case-report does emphasize on the numerous presentations of primary liver lymphoma in HIV-Infected patient, and we illustrate the interest of MRI using a new intravenous contrast agent critical for differential diagnosis.

Abstract
We report a case of composite lymphoma consisting of peripheral T-cell lymphoma and an anaplastic variant of diffuse large B-cell lymphoma (DLBCL) and associated with Epstein-Barr virus (EBV) infection and strong p53 expression. A 65-year-old Japanese woman developed fever and generalized lymphadenopathy. A biopsy of the cervical node revealed the morphology of malignant lymphoma with 2 kinds of lymphoma coexisting in 1 lymph node. One lymphoma type consisted of immunoblastic large cells with the T-cell marker phenotype CD3+, CD45RO/UCHL-1+, CD20/L26-, CD79-, CD10-, CD30-, and CD15-; the other type consisted of large cells with abundant cytoplasm and pleomorphic nuclei with the marker phenotype CD79+, CD20/L26+, CD45RO/UCHL-1-, CD3-, CD10-, CD30+, NPM/ALK-, and CD15-. Therefore, the diagnosis was composite lymphoma of peripheral T-cell lymphoma and an anaplastic variant of DLBCL, stage IVB, because the patient had bone marrow involvement with peripheral T-cell lymphoma. The biopsy led to findings of latent type II EBV-associated lymphoma in both the peripheral T-cell lymphoma and the anaplastic variant of DLBCL as the result of positive signals for EBV small RNAs by in situ hybridization, positive immunostaining results for EBV latent membrane protein 1 antibody, and negative immunostaining results for EBV nuclear antigen 2. Immunostaining of the mass with p53 antibody also yielded positive results for both types of lymphoma cells. This case suggests that the immunocompromised state of this patient with EBV-related peripheral T-cell lymphoma allowed the emergence of an EBV-related anaplastic variant of DLBCL and suggests a close relationship between p53 expression and latent EBV infection.

Abstract
Hepatitis C virus (HCV) has been implicated in the etiology of malignant lymphomas. We estimated the risk of lymphoma associated with detection of HCV infection. Cases (n = 529) were consecutive patients newly diagnosed with a lymphoid malignancy between 1998 and 2002 in 4 centers in Spain. Lymphomas were diagnosed and classified using the WHO Classification. Controls (n = 600) were hospitalized patients matched to the cases by 5-year age group, gender and study center. Several medical conditions associated with severe immunosuppression precluded the eligibility of controls. Patients underwent a personal interview and blood sampling. HCV positive subjects were considered those with antibody response to third generation ELISA or detection of HCV RNA with Amplicor 2.0. Cases were systematically tested for HIV antibodies. We used the chi(2) test and unconditional logistic regression to estimate the odds ratio (OR) and 95% confidence interval (95% CI) for lymphoma associated with HCV. HCV infection was detected in 40 cases (7.5%) and 23 (3.8%) control subjects. Six of 16 patients with HIV-related lymphomas and 4 of 8 organ-recipient-related lymphomas were HCV positive. The analysis, excluding HIV-infected subjects and organ recipients, led to a prevalence of HCV of 5.9% among cases and 3.8% among controls. The age-, gender- and center-adjusted OR for all lymphomas was 1.58 (95% CI = 0.89-2.79). Among all lymphoma categories, HCV was associated with an increased risk of low grade B-cell lymphomas not otherwise specified (NOS) (OR = 35.98, 95% CI = 4.70-275.4). A 2-fold excess risk associated to HCV was observed for marginal B-cell lymphomas, diffuse large B-cell lymphoma and lymphoma B NOS but the associations were not statistically significant. HCV infection is associated with an increased risk of a broad spectrum of lymphoid neoplasms among non severely immunocompromised subjects in Spain.

Abstract
OBJECTIVE To investigate the characteristic of ALK protein expression in anaplastic large cell lymphoma (ALCL) and the relationship between ALCL and Epstein-Barr virus (EBV). METHODS Histopathological method was used to study the morphological characteristic. Immunohistochemical staining was used to detect ALK protein and other antigen. EBV-encoded EBER was detected by in situ hybridization. RESULTS All 2 cases of primary cutaneous ALCL were ALK protein negative. 20 cases of systemic ALCL were found to be ALK protein positive in 12 cases (60%), which included 8 cases of common variant, 3 cases of lymphohistiocytic variant and 1 case of small cell variant; the expression of ALK protein showed no significant difference between these 3 variants (P>0.05). The ALK protein expression pattern was characterized by the brown-stained nucleus and cytoplasm of the cells, but in 2 cases only the cytoplasm was stained. The patients with ALK protein expression were younger than those without ALK protein expression (P<0.05); all 22 cases were EBER negative. CONCLUSION High incidence of the expression of ALK protein was seen in ALCL, especially in ALCL of younger patients. No relationship was observed between EBV and ALCL in this study.

Abstract
Although extranodal presentation occurs in the majority of cases of acquired immunodeficiency syndrome-associated non-Hodgkin lymphoma, the esophagus is only rarely affected. We discuss two patients with acquired immunodeficiency syndrome who presented with dysphagia and weight loss, who were found to have human immunodeficiency virus-associated primary esophageal lymphoma. Both patients died within a few weeks of diagnosis, reflecting the poor prognosis associated with this malignancy. Primary esophageal lymphoma should be considered in the differential diagnosis in a human immunodeficiency virus-seropositive patient presenting with dysphagia.

Abstract
Simian virus 40 (SV40) is known to induce primary brain tumors and lymphomas in animal models. Recently, it was also associated with the pathogenesis of human non-Hodgkin's lymphomas. In the present study, we investigated primary central nervous system lymphomas (PCNSL), a defined subgroup of diffuse large B-cell lymphoma confined to the central nervous system, for the presence of SV40 DNA. Frozen tissue samples of 23 PCNSL derived from human immunodeficiency virus-negative patients were analyzed by two different, fully nested polymerase chain reaction protocols. SV40 DNA sequences could not be detected in any of these samples. Thus, SV40 can be added to the list of viruses that have already been excluded as pathogenetically relevant cofactors in PCNSL.

Abstract
The frequency of Epstein-Barr virus (EBV) in anaplastic large cell lymphoma (ALCL) has been controversial. The interpretation of previous studies is complicated by the use of nonuniform EBV detection methods and the inclusion of cases of CD30-positive diffuse large B-cell lymphoma and so-called "ALCL, Hodgkin-like," as defined in the Revised European-American Lymphoma classification scheme. In the current World Health Organization (WHO) classification system, both of these tumors are excluded from the ALCL category. Also, recently developed antibodies (eg, the antibody specific for PAX-5/B-cell-specific activator protein [BSAP]) provide new, sensitive tools for identifying neoplasms of B-cell lineage that can morphologically resemble ALCL. In this study we evaluated 64 cases of ALCL of T- or null-cell lineage, defined according to the WHO classification system, for the presence of EBV. All tumors were negative for B-cell antigens, including PAX-5/BSAP and CD20 or CD79a. The study group included 27 (42%) anaplastic lymphoma kinase (ALK)-positive (18 T-cell and 9 null-cell) and 37 (58%) ALK-negative (30 T-cell and 7 null-cell) tumors analyzed by in situ hybridization for EBV-encoded RNA (EBER) or immunohistochemistry for EBV-latent membrane protein type 1. All 64 cases were negative for EBV. We conclude, based on the current definition of ALCL in the WHO classification, there is no role for EBV in ALCL arising in Western patients. We suggest that published reports of EBV in a small proportion of ALCL cases in Western patients can be explained by the inclusion of tumors no longer considered to be in the current classification of ALCL, such as CD30-positive anaplastic tumors of B-cell origin.
