Abstract
Patients with rheumatoid arthritis are at increased risk of hematological malignancies, especially when exposed to immunosuppressive therapy. The mechanisms of lymphomagenesis remain poorly understood but factors implicated include high disease activity, exposure to antitumoral necrosis factor medications, and Epstein–Barr virus infection. Lymphoid malignancies of T-cell origin are uncommon in patients with rheumatoid arthirits. Clinical presentation with associated hemophagocytic lymphohistiocyotsis is rare and confers a poor prognosis. This case report illustrates a case of a patient with long-standing rheumatoid arthritis and an iatrogenic peripheral T-cell lymphoma with secondary hemophagocytic lymphohistiocytosis who achieved a complete response after intensive chemotherapy.

Abstract
Purpose To present two cases of rapidly growing tumors in the ocular adnexa. Both tumors were Epstein-Barr virus (EBV) positive peripheral T-cell lymphoma. Methods Case 1 was a 60-year-old man with a non-tender ulcerating tumor involving the lateral third of both upper and lower right eyelid. Case 2 was a 55-year-old man with a swelling of the left eyelid expanding cranially and dislocating the left eye, resulting in proptosis and diplopia. Both patients underwent incisional biopsy that did not disclose the malignant nature of the tumors. Clinical evaluation resulted in suspicion of malignancy and surgical excision was performed. Results The tumors were found to be consistent with EBV-positive peripheral T-cell lymphoma. Conclusions Peripheral T-cell lymphoma is uncommon but a diagnosis to be considered in a patient with a tumorous lesion in the eye region. Furthermore, peripheral T-cell lymphoma may be EBV-positive.

Abstract
Epstein-Barr virus (EBV)-encoded RNAs (EBER) in tumor tissue and cell-free plasma EBV-DNA (pEBVd) are detected in EBV-associated lymphomas. Studies have suggested that EBER+ peripheral T-cell lymphomas (PTCL) have worse prognosis but the role of EBV in these neoplasms remains unclear. pEBVd is quantitative and more easily amenable to standardization than EBER, but frequency of pEBVd detection, clinical impact and agreement with EBER status in PTCL are unknown. We retrospectively assessed frequency of detectable pre-treatment pEBVd, presence of EBER in tumor tissue, and outcomes in 61 of 135 EBV-assessable PTCL patients. Fifteen of 61 patients (24.5%, 95% CI: 14-37%) were pre-treatment pEBVd+, with no significant differences in baseline characteristics or treatment between pEBVd+ and pEBVd- patients. EBER-ISH was performed on 10 pEBVd+ and 35 pEBVd- tumors. All 10 pEBVd+ patients were EBER+, but 9 pEBVd- patients were also EBER+. With median follow up of 24 months (range 1-96), overall survival (OS) was shorter in pEBVd+ compared to pEBVd- patients (13 vs. 72 months; p = 0.04). In our retrospective study, pre-treatment pEBVd was elevated in 25% of PTCL patients, was highly specific for EBER+ tumors, and was associated with shorter survival. pEBVd should be further explored as a prognostic variable and tumor biomarker in PTCL.

Abstract
While Epstein-Barr virus (EBV) was initially discovered and characterized as an oncogenic virus in B cell neoplasms, it also plays a complex and multifaceted role in T/NK cell lymphomas. In B cell lymphomas, EBV-encoded proteins have been shown to directly promote immortalization and proliferation through stimulation of the NF-κB pathway and increased expression of anti-apoptotic genes. In the context of mature T/NK lymphomas (MTNKL), with the possible exception on extranodal NK/T cell lymphoma (ENKTL), the virus likely plays a more diverse and nuanced role. EBV has been shown to shape the tumor microenvironment by promoting Th2-skewed T cell responses and by increasing the expression of the immune checkpoint ligand PD-L1. The type of cell infected, the amount of plasma EBV DNA, and the degree of viral lytic replication have all been proposed to have prognostic value in T/NK cell lymphomas. Latency patterns of EBV infection have been defined using EBV-infected B cell models and have not been definitively established in T/NK cell lymphomas. Identifying the expression profile of EBV lytic proteins could allow for individualized therapy with the use of antiviral medications. More work needs to be done to determine whether EBV-associated MTNKL have distinct biological and clinical features, which can be leveraged for risk stratification, disease monitoring, and therapeutic purposes.

Abstract
The cytotoxic T-cell and natural killer (NK)-cell lymphomas and related disorders are important but relatively rare lymphoid neoplasms that frequently are a challenge for practicing pathologists. This selective review, based on a meeting of the International Lymphoma Study Group, briefly reviews T-cell and NK-cell development and addresses questions related to the importance of precise cell lineage (αβ-type T cell, γδ T cell, or NK cell), the implications of Epstein-Barr virus infection, the significance of anatomic location including nodal disease, and the question of further categorization of enteropathy-associated T-cell lymphomas. Finally, developments subsequent to the 2008 World Health Organization Classification, including the recognition of indolent NK-cell and T-cell disorders of the gastrointestinal tract are presented.

Abstract
BACKGROUND AND AIM Little is known about the clinicopathological characteristics of primary gastrointestinal T-cell lymphomas (PGITL). This study evaluated the clinical and endoscopic features of the pathological subtypes of PGITL. METHODS Forty-two lesions in 36 patients with PGITL were assessed, including 15 enteropathy-associated T-cell lymphomas (EATL), 13 peripheral T-cell lymphomas (PTCL), 10 NK/T-cell lymphomas (NK/TL), and four anaplastic large cell lymphomas (ALCL). RESULTS PTCL occurred more frequently in the stomach and duodenum and NK/TL more frequently in the small and large intestines (P = 0.009). The endoscopic features of the four subtypes were similar (P = 0.124). Fifteen of 41 lesions (36.6%) were Epstein-Barr virus (EBV) positive, with NK/TL more likely to be EBV positive than the other types (P < 0.001). First endoscopy and first computed tomography (CT) scan indicated that 65.4% and 51.4% of the lesions, respectively, were malignant, and that 43.2% and 42.3%, respectively, were GI lymphomas. The two modalities together correctly diagnosed about half of the lesions before biopsy. Intestinal perforation was associated with small bowel location (P < 0.001) and infiltrative type (P = 0.009), and was more common in NK/TL than in the other subtypes (P = 0.015). Multivariate analysis showed that higher international prognosis index (P = 0.008) and the presence of complications (P = 0.006) were associated with poor prognosis. Survival was poorer in patients with small bowel lesions than with lesions at other locations (P = 0.048). CONCLUSIONS The four main pathological types of PGITL differed in clinical characteristics. As PGITL was often not diagnosed by initial endoscopic or radiological examination, a high index of suspicion is necessary to ensure its early diagnosis.

Abstract
This study investigated the prevalence of Epstein-Barr virus (EBV) infection and its association with P53 expression in a panel of 87 previously untreated nodal non-Hodgkin lymphomas (NHLs) from India. Polymerase chain reaction specific for Epstein Barr nuclear antigen 1 (EBNA1) and EBNA-3C was performed on the lymphnode tissue DNA, while P53 expression was analyzed by immunohistochemistry. EBV, predominantly type A strain, was detected in 27/87 (31%) nodal lymphoid malignancies, 11/46 diffuse large B-cell lymphomas, 6/17 follicular lymphoma, 4/6 anaplastic large cell lymphomas (ALCL), 5/11 peripheral T-cell lymphomas (PTCL) and 1/7 lymphoblastic lymphomas. EBV infection was more frequently observed in a specific subset of nodal NHL, suggesting a causative role of EBV infection in the pathogenesis of ALCL and PTCL. There was no significant association between EBV and P53 expression in our series of NHL patients.

Abstract
Most primary intestinal natural killer (NK)-cell and T-cell lymphomas (PINKTL) in the Northern Europe are enteropathy-associated T-cell lymphomas, a complication of celiac disease, which is rare in the East. Primary intestinal NK-cell lymphoma is extremely rare and is poorly characterized. We investigated 30 cases of PINKTL from Taiwan with male: female at 2:1, median age at 55.5, 80% with jejunal/ileal involvement, 77% with perforation, 27% with multicentric tumors, and 67% at stage IE. All 7 cases tested for serum IgA anti-tissue transglutaminase were negative. Only 3 (10%) tumors showed enteropathy. Six (20%) were NK-cell lymphoma and 24 (80%) were T-cell lymphoma. The tumor cells in 21/30 (70%) cases were small to medium sized, which correlated with the coexpression of both CD8 and CD56. All tumors expressed at least 1 cytotoxic marker. All 6 NK-cell lymphomas were negative for betaF1, diffusely positive for Epstein-Barr virus-encoded mRNA (EBER), and polyclonal for T-cell receptor gene rearrangement. Five (22%) of the 24 T-cell tumors expressed betaF1, 8 (35%) of the 23 tumors were positive for EBER, and 20 (95%) of the 21 tumors were clonal for T-cell receptor. The overall 1-year survival was 36%. Univariate regression analysis showed that NK-cell lineage, multicentricity, and perforation were associated with poor prognosis. NK-cell lineage (P=0.037) was a poor prognostic factor by multivariate Cox proportional hazard regression analysis. PINKTL in Taiwan is predominantly not enteropathic with a high frequency of perforation, small to medium tumor cell size and cytotoxic phenotype. Primary intestinal NK-cell lymphoma carries a very poor prognosis, and is probably a distinct entity.

Abstract
We report on a series of 58 cases of angioimmunoblastic T-cell lymphoma (AILT) and 59 cases of peripheral T-cell lymphoma, unspecified (PTCL-NOS). Subsets of cases from both diagnostic groups were complicated by associated B-cell proliferations, and we performed B- and T-cell clonality studies and in situ hybridization for Epstein-Barr virus (EBV) to investigate the relationship between B-cell proliferation, B-cell clonality, and EBV. Using multiplex polymerase chain reaction assays based on the BIOMED-2 collaborative study, we detected TCRgamma T-cell clones in 78 and 81% of AILT and PTCL-NOS cases, respectively, and IGH B-cell clones in 34 and 35% of AILT and PTCL-NOS cases, respectively. The majority of cases contained EBV-positive cells, including 50% of AILT and 57% of PTCL-NOS cases, and cases with B-cell proliferations were more often EBV-positive. Although a relatively high rate of B-cell clonality has been shown for AILT, our findings for PTCL-NOS differ from previous reports in that B-cell clonality was relatively frequent. Overall, a positive B-cell clone correlated, in part, with the presence of a B-cell proliferation but not with EBV. Our findings demonstrate that B-cell clonality is a common finding in AILT and PTCL-NOS, and its presence should not negate the diagnosis established by morphologic, immunophenotypic, and clinical findings.

Abstract
The association of Epstein-Barr virus (EBV) with human immunodeficiency virus-negative T-cell lymphoma was examined in 68 patients using the polymerase chain reaction (PCR) with DNA obtained from formalin-fixed paraffin-embedded tissues and an in situ hybridization technique. EBV-encoded RNA (EBER) was detected in 43 of 68 cases (63%) of peripheral T-cell lymphoma: in 100% (11 of 11 cases) of NK/T-cell lymphomas, 70% (14 of 20 cases) of angioimmunoblastic T-cell lymphomas (AILT) and 49% (18 of 37 cases) of other types of peripheral T-cell lymphoma. A positive band was also detected at high incidence (36 of 65 cases; 55%) in a PCR analysis using primers to detect the Bam HI-W fragment of EBV. In the immunohistochemical analysis using a monoclonal antibody to latent membrane protein 1 (LMP-1) of EBV, one of the EBV-encoded latent gene products, LMP-1, was found to be expressed in 13 of 64 cases (20%), but EBNA-2 was not expressed in all the cases examined (0 of 59 cases; 0%). The 5-yr survival rate was 28% for peripheral T-cell lymphomas overall, 0% for NK/T-cell lymphomas, 38% for AILTs and 28% for other types of peripheral T-cell lymphoma. The difference in the overall survival rate between NK/T-cell lymphoma and non-NK/T-cell lymphoma was significant (P = 0.0498 by Log-rank test). Among peripheral T-cell lymphoma patients overall, the group severely infected with EBV (EBER-ISH ++) had a lower 5-yr survival rate (8%) than the group slightly (EBER-ISH +) or not infected (38%; P = 0.0013).

Abstract
To analyze the clinicopathologic characteristics of childhood non-Hodgkin's lymphoma (NHL) associated with Epstein-Barr virus (EBV), EBER in situ hybridization was performed in 80 cases of NHLs. EBER-positive lymphomas account for 25% (20/80) and include NK/T-cell lymphoma (6/6), aggressive NK-cell leukemia (1/1), peripheral T cell lymphoma (5/11), diffuse large B-cell lymphoma (5/14), hydroa-like T-cell lymphoma (1/1), marginal zone B-cell lymphoma (1/2), and post-transplantation lymphoproliferative disorder (1/1). Other types including 19 cases of Burkitt's lymphoma were negative. For 9 EBER-positive cases, immunohistochemical staining for LMP-1, and EBNA-2 was performed to determine the EBV latency pattern. Two of nine EBER-positive cases expressed both LMP-1 and EBNA-2. Clinically, patients with EBV-positive B-cell lymphomas were cured with chemotherapy, whereas EBV-associated NK- and T cell lymphomas pursued fatal clinical course. In conclusion, EBVs infected in childhood NHLs are frequently associated not only with NK- and T- cell lymphomas but also large B-cell lymphomas.

Abstract
The purpose of this study was to evaluate the prevalence of EBV in non-Hodgkin's lymphomas occuring in non-immunocopromised patients in Tunisia through a series of 126 cases. EBV was investigated by EBER oligonucleotide in situ hybridization (ISH) and LMP1-immunohistochemistry. Serological study of EBV has been performed before therapy in 28 patients. EBV was detected in tumor cells by ISH in 28/126 (22.2%) cases. Variable proportions of tumor cells were positive. LMP1 was identified in only 8 cases. EBV was more frequently observed in T-cell lymphomas (9/24 patients; 37.5%) than in B-cell lymphomas (19/102 patients; 18.6%) (p=0.04). There was a strong relationship between EBV and small intestine lymphomas (6/8 patients; 75%) and T/NK nasal type lymphomas (3/3 patients; 100%). EBV serological reactivation was noted in 7/13 patients in clinical stages III/IV and in only 1/10 patients in stages I/II (p=0.03). In conclusion, the prevalence of EBV in Tunisian non-Hodgkin's lymphomas is low but variable depending on the histological type and anatomical location with a predilection for small intestine and nasal lymphomas.

Abstract
Natural killer/T-cell lymphoma (NKTL) and peripheral T-cell lymphomas (PTCL) are prevalent in the Asian population and exhibit a high association with the Epstein-Barr virus (EBV). Moreover, differentiation of these two groups is often difficult and problematic. We investigated 35 cases of NKTL (22 nasal cases and 13 extranasal cases) and 30 cases of PTCL in terms of their clinical features, immunohistology, EBV positivity, EBV strain-type polymorphism and latent membrane protein 1 (LMP1) deletion variant distribution. Eighteen cases (82%) of nasal NKTL and seven (54%) of extranasal NKTL showed EBV positivity by EBV in situ hybridization. Fifteen cases (50%) of PTCL revealed EBV positivity. EBV strain type A was predominant in NKTL (18:5), and EBV strain types A and B were distributed evenly in PTCL (6:6). EBV-positive patients had significantly shorter survival than EBV-negative patients (P < 0.05), and EBV positivity correlated with advanced clinical stage (P < 0.05). Patients harboring type A EBV showed slightly poorer prognoses than those having type B, though it was not obviously statistically different (P = 0.07). The LMP1 deletion variant was prevalent in both NKTL (three wild-type LMP1, 15 deletion variants) and PTCL (three wild-type LMP1, eight deletion variants, two coexistent forms) patients, but did not have prognostic impact. Our results indicate that EBV acts as a negative prognostic factor in NKTL and PTCL, and that the intrinsic properties of a specific viral strain might influence the clinical behavior of these diseases.

Abstract
BACKGROUND Non-Hodgkin lymphoma (NHL) represents a heterogeneous group of tumors that vary with regard to their biologic aggressiveness and clinical course. In in vitro studies, matrix metalloproteinase 9 (MMP9) was reportedly expressed by human NHL cells and elevated levels of MMP9 have been observed in a subset of patients with high-grade NHL. METHODS The expression of MMP2 and MMP9 was evaluated in 158 patients with NHL and the relation between the expression of these proteins and clinicopathologic factors was analyzed. All but 1 patient had received radiation therapy and 92 patients also were treated with intensive combination chemotherapy. RESULTS Nearly all the patients with extranodal natural killer NK/T-cell lymphoma nasal type and anaplastic large cell lymphoma, T-cell/null cell type expressed MMP9. In contrast, only a small fraction of the patients with mucosa-associated lymphoid tissue (MALT) lymphomas and follicular lymphomas expressed MMP9. Approximately 50% of the diffuse large B-cell lymphoma (DLBCL) cases expressed MMP9. The expression of MMP2 was noted in some of the patients with DLBCL and nasal NK/T-cell lymphoma. The overall survival rates of patients who expressed MMP9 were significantly lower than that of those who did not. Such a correlation was not demonstrated in MMP2 expression. When MMP9 expression was analyzed in DLBLC patients, the overall survival rates of patients who expressed MMP9 were significantly lower than those who did not express MMP9. Chemotherapy was associated with better overall survival in DLBCL patients who expressed MMP9. Overall survival rates of T-cell/NK-cell lymphoma patients who expressed MMP9 appeared to be lower than that in those who did not express MMP9. However, chemotherapy was not found to improve overall survival in patients who expressed MMP9. CONCLUSIONS MMP9 expression was observed in patients with aggressive NHL and was characterized by poor overall survival.

Abstract
Epstein-Barr virus (EBV) is a large lymphotrophic DNA virus that establishes life-long residency in the infected host and is associated with a number of human tumors. The EBV genome encodes proteins essential for persistence, an oncoprotein, and proteins that render it vulnerable to the host's immune system; therefore, EBV gene transcription is tightly regulated. One critically important regulatory mechanism utilized by EBV is DNA methylation. Methylation of cytosines within CpG dinucleotides at promoter regions is important for gene silencing and genome integrity. Although most parasitic elements are methylated in mammalian cells never to be reactivated again, EBV has evolved to utilize DNA methylation to maximize persistence and cloak itself from immune detection. EBV's reliance on DNA methylation also provides a unique therapeutic strategy for the treatment of EBV-associated tumors. DNA demethylating agents are capable of reactivating transcription of highly immunogenic viral proteins, rendering tumor cells susceptible to killing by the host immune system, and inducing the viral lytic cycle which culminates in cell lysis.

Abstract
This study analyzes the prevalence of T-cell non-Hodgkin's lymphoma (T-NHL) in a major referral center of Pakistan and its association with Epstein-Barr virus (EBV). Ninety-two cases of T-NHL were characterized on the basis of morphology, immunohistochemistry and genetic features. The prevalence of T-NHL was 22.2% of the total NHLs diagnosed during the eight years period (1992-1999). Polymerase chain reaction (PCR) technique was used to assess T-cell clonality in paraffin-embedded tissues of known T-NHL. Amplifiable DNA was isolated from all the cases, which were further studied for T-cell receptor (TcR)-beta, gamma, delta, and IgH chain gene rearrangements. Out of 92 cases 51 cases showed clonal product and 33 demonstrated polyclonal smear for beta, gamma, or delta chain genes, respectively, whereas 8 cases exhibited IgH chain gene rearrangement for FR2 region. This study demonstrated frequent presence of EBV in T-NHL (55.4%) by PCR, which were further tested for the localization of the virus by in situ hybridization (ISH). The extent of polymorphism in EBV genome was studied by single stranded conformation polymorphism (SSCP) technique for Bam HI E, K, N and Z regions. Hypervariability in Bam HI K, and N regions was noticeably higher compared to E or Z regions. In conclusion, our study demonstrated that the prevalence of T-NHL in Pakistan is slightly higher to that reported for Western communities. In addition, the frequency of EBV genome in T-NHL is intermediate as compared to other studies. No association was established between EBV variants differentiated on the basis of sequence heterogeneity in Bam HI K, N, E and Z regions with the manifestation of different subsets of T-NHL.

Abstract
The aim of this study is to report 46 new cases of canine T-cell lymphomas among a series of 140 lymphomas studied by immunophenotyping (incidence 32.8%). According to the updated Kiel classification adapted to the canine species, 13 were classified as low-grade and 33 as high-grade lymphomas. Among the low-grade lymphomas, five were small clear-cell lymphomas, three were pleomorphic small-cell lymphomas, and five mycosis fungoides. Among the high-grade cases, there were 11 pleomorphic mixed-, small-, and large-cell lymphomas, 6 pleomorphic large-cell lymphomas, 11 lymphoblastic lymphomas, and 5 unclassifiable high-grade plasmacytoid lymphomas. The cytohistologic features were highly suggestive of a T-cell phenotype on the basis of cell morphology (irregular nuclei and clear cytoplasms) (30/46 cases), a T-cell zone pattern, and the presence of hyperplastic postcapillary venules (22/46 cases). All 46 cases were CD3+ CD79a-, and among 34 cases investigated for CD4 and CD8 expression, 13 were CD4+CD8-, 13 were CD8+CD4-, and 8 were CD4CD8 double positive or double negative. The pleomorphic mixed lymphomas were mainly CD4+CD8- (6/7) and the lymphoblastic lymphomas were double positive or double negative (6/8). The main clinical, hematologic, and biochemical features were generalized (28/46) or regional lymphadenopathy (16/46), hepatosplenomegaly (15/46), extranodal involvement (11/46), mediastinal mass (9/46), and leukemia (8/46), which were mainly present in cases of lymphoblastic lymphomas and hypercalcemia (16/46).

Abstract
OBJECTIVE The purpose of this study was to histologically characterize a series of oral non-Hodgkin's lymphomas (NHLs) and to investigate latent and lytic Epstein-Barr virus (EBV) infection in these. STUDY DESIGN The revised European-American Lymphoma classification system (41) was used to categorize 58 cases of oral NHL, which included 9 immunosuppression-related NHLs. EBV infection was determined by in situ hybridization for Epstein-Barr virus-encoded RNA and by immunohistochemistry for the EBV antigens latency membrane protein, Epstein-Barr nuclear antigen-2 (EBNA2) and Z EBV replication activator protein. RESULTS Most tumors were B-cell lymphomas (78%), but the proportion of T-cell lymphomas was surprisingly high (22%). The most common histologic subtypes were diffuse large B-cell lymphomas (45%), peripheral T-cell lymphomas (19%), and follicle center lymphomas (14%). Two thirds of the known immunosuppression-related NHLs were T-cell lymphomas. All of the immunosuppression-related tumors were EBV-infected, whereas the EBV infection rate in the NHLs of the remaining patients presumed to be immunocompetent was only 9%. Most EBV-positive tumors expressed neither of the latent antigens (ie, latency membrane protein and Epstein-Barr nuclear antigen-2), and coexpression of the 2 was observed only in immunosuppressed patients. Z EBV replication activator protein expression, which is indicative of replicative infection, occurred only in immunosuppressed individuals. CONCLUSIONS Diffuse large B-cell lymphomas were the most common histologic subtype of oral NHLs, but T-cell lymphomas were relatively common and frequently occurred in states of immunosuppression. EBV may play a limited role in the initiation of lymphoma in the immunocompetent patient, but the virus may be of importance in progression of the disease in those patients with more aggressive tumors, as immunosuppression occurs.

Abstract
T-cell lymphomas are a biologically heterogeneous group of diseases with varying clinical presentations and outcomes. We tried to understand the effect of Epstein-Barr virus (EBV) on lymphogenesis, prognostic factors and drug resistance of T-cell lymphomas, and to establish their relationship with international prognostic factors. Formalin-fixed paraffin-embedded tissue sections from 35 patients (12 women and 23 men) with T-cell lymphomas were examined to detect the presence of EBV using RNA in situ hybridization for EBV-encoded small nuclear RNA (EBER) 1/2 and immunohistochemical stain for latent membrane protein (LMP)-1. We also tried to establish the expression of p53 and P-glycoprotein (P-gp) using immunohistochemistry. The distribution according to the subgroup was: two T-lymphoblastic lymphomas, 13 NK/T-cell lymphomas, one angioimmunoblastic T-cell lymphoma, 17 peripheral T-cell lymphomas, unspecified, and two anaplastic large cell lymphomas. The EBER was detected in 15 of 35 T-cell lymphomas (42.9%) and among these it was detected in five of 17 nodal lymphomas (29.4%) and 10 of 18 extranodal lymphomas (55.6%). There was close correlation between EBER positivity and NK/T-cell lymphoma (P = 0.032). Expression of LMP was found in a proportion of tumor cells in seven of the 15 EBER-positive cases (46.7%). There was no correlation between EBER expression and complete response (CR rate), but coexpression of EBER and p53 was associated with treatment failure (P = 0.047). The 18 patients (51.4%) with p53 expression had significantly poorer outcomes compared with the 17 patients without p53 expression (CR rate, P < 0.0005; overall survival, P = 0.0102). Twenty of 35 patients (57.1%) were positive for P-gp expression. P-gp expression was significantly associated with treatment failure (P = 0.001) and overall survival (P = 0.0089). Seventeen of 35 patients (48.6%) treated with systemic chemotherapy or radiation therapy achieved a CR after initial treatment. When the prognostic factors were grouped using the international prognostic index, the CR rate was 58.8% for the low risk group, 50.0% for the low-intermediate risk group, 14.3% for the high-intermediate risk group, and 0% for the high risk group. In conclusion, high incidence of EBV was detected among Korean patients with T-cell lymphomas. Our study supports the prediction that patients who express p53 and P-gp have a poorer prognosis than those who do not and this should be considered when treatment strategies for individual patients are selected.

Abstract
We have investigated 114 cases with diffuse large B-cell lymphoma (DLBCL) to clarify the characteristics of DLBCL with Epstein-Barr virus (EBV) infection. Thirteen cases (11.4%) showed EBV-encoded RNA 1 (EBER1) signals by RNA in situ hybridization. EBV-encoded latent membrane protein 1 (LMP1) and EBV-encoded nuclear antigen 2 (EBNA2) were expressed in 11 and 4 cases, respectively. Expression of CD30, Bcl-6 and immunoglobulin (Ig) was found in 92%, 31% and 23% with EBV(+) DLBCL, and in 15%, 79% and 82% with EBV(-) DLBCL, respectively. The sequence of rearranged Ig heavy chain (IgH) variable (V) region gene was analyzed in 5 cases with EBV(+) DLBCL and 61 cases with EBV(-) DLBCL. Somatic mutation was found in all cases except one with EBV(-) DLBCL. Average mutation frequency was 9.6% in EBV(+) DLBCL vs. 11.5% in EBV(-) DLBCL. The rates of replacement mutation vs. silent mutation (R / S values) in complementarity determining region II and framework region III were 2.7 and 1.5 in EBV(+) DLBCL, 2.6 and 1.4 in EBV(-) DLBCL. Crippling mutation generating a stop codon was found in 2 of 5 cases (40%) with EBV(+) DLBCL, but none of 61 cases (0%) with EBV(-) DLBCL. These findings suggest that EBV(+) DLBCL and EBV(-) DLBCL were both derived from germinal center (GC) or post-GC B cells, and EBV(+) DLBCL frequently have a non-functional IgH gene owing to crippling mutation.

Abstract
This paper reports the case of a patient with a composite lymphoma consisting of nodular sclerosing Hodgkin's disease and peripheral T-cell lymphoma. The Hodgkin and Reed-Sternberg (HRS) cells harboured the Epstein-Barr virus (EBV) and displayed a type II EBV latency (LMP1(+)/EBNA2(-)), whereas the neoplastic T-cells were EBV-negative. Four years later, the patient presented with a relapse of the peripheral T-cell lymphoma. In situ hybridization revealed numerous EBV-carrying lymphocytes, which were shown to be polyclonal B-cells with a latency III pattern of EBV gene expression (LMP1(+)/EBNA2(+)). This observation suggests that impairment of EBV-specific immunity in the micro-environment of T-cell lymphomas may facilitate the outgrowth of EBV-carrying B-lymphocytes and emphasizes the importance of determining the phenotype of EBV-infected cells, particularly when studying T-cell lymphomas. The results further suggest that the HRS cells and neoplastic T-cells were of different clonal origins. The detection of EBV-carrying cell populations admixed with the neoplastic T-cells at primary presentation and at relapse raises the possibility that the growth of the T-cell lymphoma was dependent on the presence of such cells.

Abstract
Infectious mononucleosis (IM), a manifestation of primary infection with EBV, is characterized by a massive expansion of the T cell population. In this study we examined this expanded T cell population regarding its EBV status, its proliferative and apoptotic activity, and its expression of apoptosis-related genes. Whereas previous studies were performed on ex vivo cultures or on peripheral blood, our investigations included in vivo analysis of IM tonsillectomy specimens (14 cases) by in situ hybridization for viral RNA (EBERs) combined with immunohistochemistry (IHC; CD3, CD45RO, CD20, CD79a, Ki-67, Bcl-2, Bax, Fas, FasL) and the TUNEL method. Of the EBER+ cells 50-70% showed expression of the B cell markers CD20/CD79a. The remainder of the EBER+ cells expressed neither B nor T cell antigens. No co-expression of EBERs and T cell antigens was detected in any of the specimens. In accordance with a high rate of apoptosis (up to 2.37%) within the expanded T cell population, Bcl-2 expression was drastically reduced and FasL expression remarkably increased. The levels of Bax and Fas expression showed no or moderate up-regulation. In conclusion, the massive expansion of IM T cells is not caused by EBV infection of these cells but merely represents an intense immune reaction. Through altered expression of Bcl-2/Bax and Fas/FasL, the activated T cells are subject to enhanced apoptosis while residing within the lymphoid tissue, which eventually allows the efficient silencing of this potentially damaging T cell response.

Abstract
A small number (4% to 6%) of primary malignant lymphomas arising in the intestines express the EBV genome. However, in these tumors, the viral genotype and the role of tumor suppressor gene p53 have not been investigated. We sought to determine what genotype of EBV is frequently involved and whether the expression of p53 is related to these tumors. We used EBER-1 in situ hybridization and polymerase chain reactions (PCRs) for EBNA-1, EBNA-2A, and EBNA-2B to detect latent infection with EBV and to determine the genotype, respectively. In addition, we performed p53 PCR-SSCP (exons 5 through 9) and immunohistochemical analysis for p53. We found that EBV type B was present in 4 of 6 cases (67%); the genotype of the remaining cases could not be determined. The p53 PCR-SSCP indicated normal migration patterns in all malignant lymphomas, despite the fact that the tumor cells were strongly immunostained for p53 protein in 5 of the 6 cases. Thus, our study demonstrates that EBV-associated non-Hodgkin's lymphomas of the intestines in Korea are strongly related to the type B EBV and not to mutations of p53 gene. We suggest that EBV-associated intestinal lymphomas may arise through an interaction between the latent proteins of EBV and the wild-type p53 protein.

Abstract
Chronic active Epstein-Barr virus (EBV) infection is manifested clinically by the persistence of infectious mononucleosis-like symptoms or its complications for a prolonged period ranging from one to several years. This syndrome may include severe disease manifestations and can be fatal. The role of EBV in the pathogenesis of chronic active EBV infection has been unclear. We investigated two Japanese patients with severe chronic active EBV infection who subsequently developed EBV-positive T-cell lymphoma. We found that the patients had evidence of EBV infection in the peripheral blood CD4+ T-cells 19 and 3 months, respectively, before the T-cell lymphoma was diagnosed. The lymphomas were infected with monoclonal EBV and expressed the EBV latency genes EBNA-1, LMP-1, and LMP-2A, a virus latency pattern referred to as latency II. Genetic studies showed that the virus detected in the T-cell lymphoma was indistinguishable from the virus in the peripheral blood CD4+ T-cells. These studies support an important pathogenetic role of T-cell infection with EBV in chronic active EBV infection and in the EBV-positive T-cell lymphoma that followed.

Abstract
One hundred thirty-seven patients with peripheral T-cell lymphomas (PTL) were examined for the presence of Epstein-Barr virus (EBV) using in situ hybridization for EBV-encoded RNA (EBER) and Bam H-fragment, lower strand frame (BHLF) and immunohistochemical stain for latent membrane protein (LMP). EBER was detected in tumor cells in 79 cases (58%); 26/66 PTL, unspecified (39%), 3/4 AILD (75%), 47/51 angiocentric lymphomas (AL) (92%), and 3/13 anaplastic large cell lymphoma (ALCL) (23%) by Revised European-American Lymphoma (REAL) classification. EBER was detected in 17/36 nodal (47%) vs. 62/101 extranodal PTLs (61%); 21/24 nasal, 12/32 Waldeyer's ring, 9/13 gastrointestinal, and 20/32 skin and soft tissue PTL. AL was consistently associated with the highest frequency of EBER among the extranodal PTL: nose (19/20), GI tracts (3/3), skin (14/15), and Waldeyer's ring (11/14). In extranodal lymphomas, coagulative-type zonal necrosis was seen almost exclusively in AL and showed correlation with EBER-positivity (P < 0.01). LMP was detected in 24 among 107 cases tested (22%). No signal for BHLF was detected in 76 cases tested, implying absent or negligible incidence of lytic infection. In conclusion, high incidence of EBV was observed in PTL among Koreans, with predilection for angiocentric lymphomas and extranodal presentation, especially involving nose, skin, and gastrointestinal tract.

Abstract
gp350 of Epstein-Barr virus (EBV) induces a strong immune response in EBV-infected individuals, but relatively little is known about the clinical relevance of this response in patients with different EBV-associated malignancies and other diseases. Using our gp350-expressing cell clones, we studied gp350-specific humoral immune responses in the sera of individuals with nasopharyngeal carcinoma (NPC), chronic symptomatic EBV infection (CEI), Hodgkin's disease (HD), acute infectious mononucleosis (IM) and healthy EBV-seropositive individuals (HI). The titres of antibody-dependent cellular cytotoxicity (ADCC) antibodies were highest in HI followed by CEI, HD and NPC. EBV-neutralizing (NA) and gp350-specific IgG antibody profiles in these conditions were: CEI > HI > NPC > HD, whereas IgA titres were the highest in NPC sera followed by CEI and HD. The sera from IM patients were found to be negative for gp350-specific ADCC and IgA activities. Sera from HI were also negative for gp350-specific IgA. A significant positive correlation was found between serum gp350 IgA and viral capsid antigen IgA and a significant negative one between IgM and ADCC titres. High IgA titres were also found in CEI and EBV-genome positive HD in addition to NPC. Importantly, gp350-specific IgA titres were of prognostic value in NPC patients. Our data provide new insights about the clinical relevance of gp350-specific immune responses in these diseases.

Abstract
Epstein-Barr virus is universally associated with endemic Burkitt's lymphoma (BL) and undifferentiated nasopharyngeal carcinoma and can be detected in a significant proportion of cases of Hodgkin's disease (HD) and peripheral T-cell lymphoma, but only rarely in sporadic B-NHL. The frequency of EBV-positivity in certain neoplasms shows important geographic variations. Both HD and sporadic BL from Latin America have shown higher rates of EBV-association than cases from Western countries. In T-NHL, the frequency of EBV-positivity is influenced by the site of the primary tumor and the phenotype of the neoplastic cells. Nasal and nasal-type T-NHL, which show a T/NK-cell phenotype with expression of CD56 are virtually always EBV-associated, whereas only a proportion of nodal, gastrointestinal and pulmonary T-NHL are EBV-infected. A recent investigation of primary intestinal lymphomas of Mexican origin demonstrated EBV-positivity in all examined cases of T-NHL and BL and a proportion of other B-NHLs. The presence of EBV was independent of the presence or absence of enteropathy. Two of 6 cases studied showed CD56 expression. The high rate of EBV-positivity independent of histologic subtype is in contrast to the low to intermediate rates of EBV-positivity found in cases of intestinal T-NHL from Western countries and indicates that geographic differences in the frequency of EBV-association of lymphoid neoplasms might also extend to a fraction of peripheral T-cell lymphomas.

Abstract
Although Epstein-Barr virus (EBV) positivity has been described in peripheral T-cell lymphomas (PTCLs) in Chinese patients, the cellular lineage of EBV-harbouring cells is unknown. Forty-four cases of PTCL were therefore studied by in situ hybridization (ISH) for EBV-encoded small non-polyadenylated RNA 1 and 2 (EBER), and the lineage of the EBER+ cells was determined by double labelling. The findings were further correlated with the clonality of EBV and the genotype of these EBER+ tumours. The results for the detection of EBV by ISH show that 23 of the 44 cases were EBER+. In 5/23 of the EBER+ cases, EBER was found in around 50 per cent of atypical cells and in 18/23 cases, EBER was found in a subpopulation of atypical cells. Among the EBER+ cases, all 15 tested showed clonal T-cell receptor gene rearrangement by Southern blot hybridization. Double labelling was successfully done in 11 EBER+ cases, and by comparison, EBER+/CD20+ B cells outnumbered the EBER+/CD3+ T cells in all these cases. EBV clonality analysis revealed that EBV was monoclonal in six EBER+ cases and biclonal in three cases. With the predominance of EBV+ B cells over EBV+ neoplastic T cells being observed in most of these cases, it is possible that the EBV-infected clonal population may be of B-cell lineage. This was supported in some cases where a faint clonal band was seen over a background smear in the gene rearrangement study of immunoglobulin heavy chain gene by polymerase chain reaction (PCR), indicating a minor B-cell clone. It is concluded that in EBV+ PTCL, EBV is preferentially localized in B cells rather than neoplastic T cells. The neoplastic T cells may support the clonal proliferation of a subpopulation of EBV+ B cells in PTCLs.

Abstract
The role of Epstein-Barr virus (EBV) in the pathogenesis of severe, chronic active EBV infection and its complications is unclear. We investigated two Japanese patients diagnosed with severe, chronic active EBV infection who subsequently developed EBV–positive T-cell lymphoma. The patients displayed abnormally high antibody titers to EBV antigens, and had evidence of peripheral blood CD4+T-cell infection with EBV, 19 months and 3 months, respectively, before the diagnosis of EBV–positive T-cell lymphoma. The lymphomas were infected with monoclonal EBV and expressed the EBV latency genes EBNA-1, LMP-1, and LMP-2. Genetic studies showed that the virus detected in the T-cell lymphoma was indistinguishable, with respect to type and previously defined LMP-1 and EBNA-1 gene variations, from virus detected in the peripheral blood T cells 19 months earlier. These studies support an important pathogenetic role of T-cell infection with EBV in chronic active EBV infection and in the EBV–positive T-cell lymphoma that followed.

Abstract
AIMS Primary intestinal T-cell lymphomas account for about 5% of all primary gastrointestinal lymphomas and are mostly associated with coeliac disease. They usually express the CD3-associated T-cell receptor alpha/beta heterodimer and HML1, and some are related with Epstein-Barr virus (EBV). As far as we know, the present report describes the first case of primary gamma-delta (gamma delta) EBV-associated intestinal T-cell lymphoma without enteropathy. Only hepatosplenic, nasal and cutaneous gamma delta T-cell lymphomas have previously been described. METHODS AND RESULTS Our case concerned a 43-year-old man with no history of coeliac disease, who presented with multifocal small bowel involvement showing high grade T-cell lymphoma with medium sized and large pleomorphic cells and a small pleomorphic T-cell component. Angioinvasion and angiocentricity were occasionally present. Immunohistochemical studies of lymphoma cells showed a T-cell gamma delta phenotype (CD3+, CD2+, TCR delta 1+, V delta 2+ and beta F1-) without expression of CD4, CD8, CD5, or HML1. Most tumour cells were positive for the cytotoxic granular proteins TiA1 and granzyme B. Rearrangement of the TCR gamma chain gene was demonstrated by polymerase chain reaction and in-situ hybridization with EBER probes revealed strong nuclear positivity in virtually all neoplastic cells. CONCLUSION We described the first case of primary intestinal gamma delta T-cell lymphoma without enteropathy in which EBV might fulfil a pathogenic role.

Abstract
BACKGROUND One hundred sixty-eight peripheral T-cell lymphomas (PTCLs) were reviewed according to the Revised European-American Lymphoma (R.E.A.L.) Classification. PATIENTS AND METHODS The cases, originally diagnosed on the basis of the Updated Kiel Classification (UKC), were all provided with histological preparations, immunophenotype, clinical information, and follow-up data. The slides were reclassified by five observers, who integrated the R.E.A.L. criteria with cell size measurements. The prognostic value of clinical and pathologic findings was assessed by univariate and multivariate analysis. RESULTS The R.E.A.L. Classification was reproducibly applied by all of the observers. Clinically, anaplastic large cell lymphomas (ALCLs) differed from the remaining PTCLs by mean age (29.5 vs. 52.9 years), bulky disease (52.3% vs. 11.3%; P = 0.000), mediastinal mass (52.7% vs. 32%; P = 0.004), and disease-free survival (68.0% vs. 38.2%; P = 0.0001). Although each histological type displayed specific clinical aspects, PTCLs other than ALCL were basically characterised by a poor clinical outcome which was not influenced by the UKC malignancy grade. At multivariate analysis, the risk of a lower complete remission rate was related to bulky disease (P = 0.001), histologic group (non-ALCL) (P = 0.01), and advanced stage (III-IV) (P = 0.0002). CONCLUSIONS The present study supports the classification of T-cell lymphomas proposed by the R.E.A.L. scheme.

Abstract
Association between Epstein-Barr virus (EBV) and nasal T-cell lymphoma (NTL) has been demonstrated. NTL has 2 types of histologic figures: one is ordinary non-Hodgkin's lymphoma (NHL) with monomorphous proliferation, and the other is polymorphic-reticulosis (PR) morphology. The presence of the EBV genome and its sub-types (A and B) were examined on paraffin-embedded specimens from 36 cases of sino-nasal lymphomas (SNL) collected from Seoul, Republic of Korea, where the frequency of NTL is high. Patients' ages ranged from 2 to 74 years (median 54 years) with a male-to-female ratio of 2.5:1. Immunophenotypically, 8 cases were B-cell type, 11 were T-cell type with CD56-, 14 were CD56+ type, and 3 were null-cell type. Five of 11 cases with ordinary NHL of T-cell type and 9 of 14 cases with PR were CD56+. The EBV genome was found by polymerase chain reaction (PCR) and in the tumor cells by in situ hybridization (ISH) in 1 of 4 B-cell type (25%), 5 of 10 T-cell type (50%), 11 of 13 CD56+ type (85%), and in both of null-cell type (100%). Of 16 cases with PR morphology, 15 (94%) were positive for the EBV genome. All of the 5 NTLs of ordinary NHL with CD56- were negative for EBV. Concerning the sub-type of EBV, 16 cases had type A, while none had type-B EBV. These findings suggest that NTL comprises 2 groups: EBV-positive NTLs are CD56+ and/or histologically PR, and EBV-negative NTLs are CD56- and histologically ordinary NHL. The current results on Korean patients, together with earlier studies on Japanese and Malaysian patients, have shown the predominance of type-A EBV in sino-nasal lymphoma in Asia.

Abstract
A high prevalence of nasal lymphoma expressing a T- or natural killer (NK)-cell phenotype (NTCL) with frequent association of Epstein-Barr virus (EBV) has been indicated in Asians. To characterize NTCL among the Japanese, the clinicopathologic features of 32 cases were evaluated and the cases were also analyzed for EBV-RNA using an ISH method. Morphologically, 31 cases were identified by atypical pleomorphic lymphoid infiltrates with polymorphous, angicentric, and necrotic features. Their lymphoma cells ranged in size from small to large and were mixed in varying proportion from case to case. The other one case showed a monomorphic 'blastic' appearance. EBV-encoded small RNA (EBER) was detected in the neoplastic cells of 27 of the 32 cases examined. In the five EBV-negative cases, one was the 'blastic' type. Clonal T-cell receptor gene rearrangement was detected in none of seven cases examined. The patients had a median follow-up of 9 months (range, 1 month to 14 years and 11 months). The Kaplan-Meier estimate of overall survival was 49% at 5 years, correlating with clinical stage. These data support the concept that most cases of NTCL are identified as tumors with T/NK-cell characteristics and EBV association, distinctly different from other peripheral T-cell lymphomas. Furthermore, the one case of an EBV-negative 'blastic' variant appears not to fit well into the pleomorphic category but more closely resembles the pathologic features of extranasal angiocentric lymphoma with lymphoblastoid appearance. This study also showed no clear difference in clinical aspects other than the original site or in prognosis, between NTCL and extranasal angiocentric lymphomas despite the higher incidence of EBV association and the tendency for that peculiar anatomical site to be restricted to the former group.

Abstract
The clinicopathological features, the immunophenotype, and the presence of Epstein-Barr virus (EBV)-associated genomes and gene products were examined in 17 cases of CD30+ anaplastic large cell lymphoma (ALCL) of B-cell type. Microscopically, the 17 cases were divided into ten cases of the monomorphic type and seven cases of the pleomorphic type. EBV was detected in 6 of 17 cases (38 per cent) by RNA in situ hybridization (ISH) with EBV-encoded RNA (EBER1). EBER1+ cases consisted of two cases (20 per cent) of the monomorphic type and four cases (57 per cent) of the pleomorphic type. The five EBER1+ cases showed clonality of the EBV genome by Southern blotting, consistent with the presence of EBV in a monoclonal proliferation. The EBV-encoded latent membrane protein 1 (LMP1) was found in all six EBER1+ cases and EBV-encoded nuclear antigen 2 (EBNA2) was present in two cases by immunohistochemistry. No expression of LMP1 or EBNA2 was observed in the EBER1-cases. The EBER1+ cases had a tendency for a more favourable prognosis than the EBER1-cases. It is concluded that EBV has an association with CD30+ ALCL of B-cell type in the Japanese population studied, and especially with the large pleomorphic type. EBV infection may play a pathoaetiological role and may influence clinical behaviour.

Abstract
Midfacial T-cell lymphomas are more prevalent in Asia than in Europe or North America. Clinically, these lymphomas are noted as one major differential diagnosis in the malignant midline granuloma syndrome. During the past years, the group of nasal T/NK cell lymphomas has been recognized that is frequently associated with EBV-infection. The aim of the current publication was to describe the clinical presentation and course of 30 patients attending the West China University of Medical Sciences, Chengdu, P.R. China, between 1991 and 1994. Clinical records were assessed and the patients were followed for 6 to 29 (mean 12.4) months. Several microscopic features thought to be associated with this entity were carefully evaluated together with immunohistochemical data. The proliferation of the tumour cells was assessed by determining the mitotic index and the ratio of MIB-1 labelled cells. In addition, the incidence of apoptotic cells was investigated by means of the in-situ end labelling (ISEL) technique. Our data confirm the expression of T-cell markers by T/NK cell lymphomas as determined by the immunohistochemistry. The apoptotic index was found to correlate with the ratio of MIB-1 labelled cells. Expression of the bcl-2 oncoprotein was not associated with increased or diminished proliferation or cell death, respectively. Eight of the thirty patients succumbed to their disease during the follow-up period. Kaplan-Meier cumulative survivals and log-rank tests revealed a significant impact of MIB-1 labelling on mean survival times.

Abstract
The Epstein-Barr virus (EBV) is the best characterized human virus known to infect most people all over the world. In most cases, primary infection with EBV is asymptomatic and the virus persists life-long without causing any disease. The availability of sensitive detection methods, however has led to the identification of a wide array of EBV-associated disease entities. Although nearly 9000 publications have been written since the first description of this virus in 1964, many questions concerning its function and infection patterns remain unanswered. The direct involvement of EBV in the pathogenesis of a disease has only been established for infectious mononucleosis and lymphoproliferative disorders in the setting of congenital or acquired immunodeficiency. Extensive investigations on the role of EBV infection in the pathogenesis of all other EBV-associated lymphoid and epithelial proliferations have led to the conclusion that EBV is not the primary causative agent but it can promote tumour development. Since the early steps in neoplastic development are difficult to assess, further studies are required to clarify the precise role of EBV infection. Furthermore, the clinical significance of the presence of EBV in neoplasia is largely unknown.

Abstract
The Epstein-Barr virus, a human herpesvirus, has been found in the neoplastic cells of numerous lymphoid malignancies, including Burkitt's lymphoma, immunodeficiency-associated lymphoproliferative disorders, nasal T/NK lymphoma, and Hodgkin's disease. The available data suggest that Epstein-Barr virus contributes to the pathogenesis of many of these neoplasms but is not directly linked to the etiology of any of these lymphomas.

Abstract
The Epstein-Barr virus (EBV) has been shown to infect T lymphocytes and is associated with two recently recognized human T-lymphoproliferative disorders: childhood EBV-associated hemophagocytic syndrome (VAHS) representing a primary or active EBV infection of T cells in young children, and the EBV-containing T cell lymphoma in adults predominantly affecting the nose, skin and gastrointestinal tract. In both diseases, hemophagocytic syndrome (HS) accounts for the major cause of mortality. The patients developing HS share common clinicopathologic features such as fever, skin lesions, lung infiltrates, hepatosplenomegaly with jaundice, cytopenias, and coagulopathy. The liver, spleen, lymph nodes, and bone marrow usually show florid histiocytic proliferation with hemophagocytosis in addition to the proliferation of atypical T lymphocytes or immunoblasts. The HS in T cell lymphoma may develop simultaneously with initial lymphoma presentation, at tumor relapse, or even during remission. The cytokines, in particular tumor necrosis factor-alpha, released from the EBV-infected T lymphocytes are presumed to cause the histiocytic activation and the subsequent hemophagocytic process. Chemotherapy or antiviral agents fail to arrest the hemophagocytic process in both diseases. Immunomodulatory treatment incorporating etoposide and intravenous immunoglobulin, however, has been effective in the control of the progression of the hemophagocytic process in a substantial number of VAHS patients. Preliminary data suggest that bone marrow transplantation may be a promising way for eliminating both the virus and the proliferating T cells. Further investigations are mandatory for combating this aggressive hemophagocytic process in EBV-associated T lymphoproliferative disorders.

Abstract
A group of 166 patients with coeliac disease was followed for a period of up to 25 years. During this time, 17 patients developed intestinal tumours that were diagnosed as lymphoma, of which 15 cases were available for review. Eleven of the lymphomas were of T-cell type (enteropathy-associated T-cell lymphoma, EATL) and two were of B-cell type. Two cases were reclassified as undifferentiated carcinoma. The interval between the diagnosis of enteropathy and the onset of lymphoma varied from less than 2 months in four patients to more than 5 years in seven. Seven of the T-cell and both B-cell lymphomas were investigated for the presence of Epstein-Barr virus (EBV) by in situ hybridization (ISH) using probes against Epstein-Barr virus-encoded RNAs (EBERs) and by immunohistochemistry with EBV-specific monoclonal antibodies. All EATL cases were negative, suggesting that EBV is not an important factor in these cases. In one of the B-cell cases, EBV was detectable by ISH and immunohistochemistry in most tumour cells in the mesenteric lymph nodes, but not in any of the tumour cells in the primary ileal tumour, indicating that in this case EBV infection was a late event in the neoplastic process. These results show that lymphoma may develop any time after the onset of coeliac disease and that in our cases of EATL, EBV was not an important factor. In some cases of EBV-related neoplasia, virus infection may be a late event.

Abstract
Seventeen of 40 cases of Hodgkin's disease (HD) and eight of 46 non-Hodgkin's lymphomas (NHL) were associated with Epstein-Barr virus (EBV) infection, judged by the EBER-1 in situ hybridization (ISH) method. Approximately 40% incidence in HD was comparable to previous reports. Young children and elderly HD patients were more prone to be found EBV positive. Fourteen of 17 HD and two of 8 NHL cases with positive EBER-1 ISH were also positive on LMP-1 immunostaining. EBV might have a role in lymphomagenesis in these cases. The fact that 7 of 8 EBV-related NHL were peripheral T cell lymphoma indicates the necessity of a larger-scale survey on this subject. As the present study revealed four cases with positive LMP-1 immunostaining but negative EBER-1 ISH (1 HD, 3 NHL), LMP-1 alone should not be regarded as a tool to prove EBV infection.

Abstract
Thirteen cases of nasal lymphomas with T-cell or natural killer (NK)-cell phenotype were studied, with attention to clinical presentation and follow-up, the presence of Epstein-Barr virus (EBV) using in situ hybridization (EBER), the immunophenotype, and the presence of cytotoxic granules. All but two patients presented with stage I disease. In three cases local progression resulted in involvement of the central nervous system. When dissemination occurred, this was predominantly to extranodal localizations, in two cases to the skin. Response to therapy was highly variable, but patients treated with radiotherapy with or without additional chemotherapy had a better prognosis than patients treated with initial chemotherapy alone. All lymphomas were associated with EBV, and most cases showed cytotoxic features, ten of which were CD56 positive. In eight cases a T-cell origin was proven, but in five cases a possible NK-cell origin could not be excluded. No clinical differences were seen between true T-cell lymphomas and possible NK-cell neoplasms. Nasal T-cell lymphomas should be considered as a distinct clinicopathological entity, strongly associated with EBV, and with cytotoxic features in most cases. No prognostic parameters were detected to predict dissemination and response to therapy.

Abstract
T-cell Non-Hodgkin's lymphomas (T-NHL) can be defined as clonal malignant proliferations related phenotypically and functionally to normal T-cell populations of the lymphoid tissue. There is increasing evidence that T-NHL with similar morphology but originating from different sites differ in their clinical behaviour, immunophenotypic features, oncogene expression and relation with oncogenic viruses such as HTLV-I and EBV. Indeed, it has been shown that the prevalence of EBV in T-NHL is related to the site of origin. Thus, EBV was found in nearly all nasal T-NHL but only in a proportion of primary nodal, lung, gastrointestinal and Waldeyer's ring T-NHL while it was undetectable in most primary cutaneous T-NHL. Besides their constant association with EBV, nasal T-NHL display peculiar clinical, histological, immunophenotypic and genotypic features. They present clinically as lethal midline granuloma and histologically as pleomorphic malignant tumours variably associated with angiocentricity, angioinvasion and necrosis. Moreover, they frequently exhibit extensive loss of T-cell antigens, including CD3 and TCR alpha beta and gamma delta proteins, usually express the Natural Killer (NK)-related CD56 antigen and frequently show absence of clonal rearrangements of TCR beta, gamma and delta loci. Therefore, among T-NHL, nasal T-NHL can be regarded as a distinct clinicopathologic entity associated with EBV, which could be derived either from immature T-cells or from NK cells.
