Abstract
AIM To report two examples of an angiocentric immunoproliferative lesion (AIL) and angiocentric angiodestructive lymphoma (AL) presenting in lymph nodes in children. Most commonly involving extranodal sites, AIL/AL rarely presents in the spleen and lymph nodes. METHODS/RESULTS Case 1 presented as a cervical lymphadenopathy in a 3 year old girl being treated for pre-B cell acute lymphoblastic leukaemia. Histological and immunohistochemistry studies revealed an Epstein-Barr virus positive (EBV+), large B cell (CD20 and CD30+) AIL with large areas of necrosis, the whole resembling lymphomatoid granulomatosis. Case 2 presented as a large supraclavicular lymphadenopathy in a 13 year old boy. Histology and immunohistochemistry revealed an EBV-, large T cell (CD45RO, CD56, and CD30+) AL, presenting the features of so called angiocentric T cell/natural killer cell lymphoma, nasal type. CONCLUSIONS The term AIL/AL refers to a heterogeneous group of conditions not unique to a particular type of lymphoid cell. These lesions are easily recognised by the histopathologist because of their extremely unusual angiocentric pattern. Although rare, AIL/AL may present as nodal lesions in children ab initio.

Abstract
HV(MNE) is an Epstein-Barr virus (EBV)-like lymphocryptovirus (LCV) originally isolated from a Macaca nemestrina with CD8(+) T cell mycosis fungoides/cutaneous T cell lymphoma (Blood 98 (2001), 2193). HV(MNE) transforms rabbit T cells in vitro and causes T cell lymphoma in New Zealand white rabbits. Here we demonstrate that HV(MNE) also immortalizes T cells from mustached tamarins but not those from owl monkeys, common marmosets, squirrel monkeys, black-capped capuchins, and humans. Cytogenetic and FACS analysis revealed the true origin and T cell lineage of the transformed tamarin T cell lines. Tamarin T cells contained HV(MNE) DNA sequence and displayed a decreased requirement for the IL-2 cytokine for growth. Thus, this EBV-like virus from M. nemestrina differs from the other EBV-like viruses found in nonhuman primates inasmuch as it appears to preferentially transform T cells.

Abstract
Epstein-Barr virus (EBV) is a ubiquitous virus that infects the majority of the world population by adulthood. The major target for infection is the B lymphocyte, and acute infection causes vigorous EBV-specific killer T-cell responses exemplified clinically by acute infectious mononucleosis (IM). EBV infection usually persists latently life-long without eliciting any clinical symptoms. Rarely, active EBV infection is prolonged, with abnormal expansions of EBV-infected T or NK cells, conditions collectively defined here as EBV-associated T/NK lymphoproliferative diseases. Hemophagocytic lymphohistiocytosis (HLH), chronic active EBV infection (CAEBV), NK lymphoma/leukemia, and T-cell lymphoma are entities included in this category. Hypersensitivity to mosquito bite (HMB) represents a unique syndrome characterized by expansion of EBV-infected NK cells in the peripheral circulation and within the inflammatory skin lesions induced by mosquito bites. Target cell specificity, defects in host immune responses, and strain differences of EBV may account for ectopic EBV infections and for the unique clinical presentations characteristic of each illness.

Abstract
In this study, we describe the cytological and cytogenetic features of six Epstein-Barr virus (EBV)-infected natural killer (NK) cell clones. Three cell clones, SNK-1, -3 and -6, were derived from patients with nasal T/NK-cell lymphomas; two cell clones, SNK-5 and -10, were isolated from patients with chronic active EBV infection (CAEBV); and the other cell clone, SNK-11, was from a patient with hydroa vacciniforme (HV)-like eruptions. An analysis of the number of EBV-terminal repeats showed that the SNK cell clones had monoclonal EBV genomes identical to the original EBV-infected cells of the respective patients, and SNK cells had the type II latency of EBV infection, suggesting that not only the cell clones isolated from nasal T/NK-cell lymphomas but also those isolated from CAEBV and HV-like eruptions had been transformed by EBV to a certain degree. Cytogenetic analysis detected deletions in chromosome 6q in five out of the six SNK cell clones, while 6q was not deleted in four control cell lines of T-cell lineage. This suggested that a 6q deletion is a characteristic feature of EBV-positive NK cells, which proliferated in the diseased individuals. The results showed that EBV-positive NK cells in malignant and non-malignant lymphoproliferative diseases shared common cytological and cytogenetic features.

Abstract
We recently established an Epstein-Barr virus (EBV)-positive gammadelta T-cell line from a nasal T/natural killer (NK)-cell lymphoma (Nagata H, Konno A, Kimura N, Zhang Y, Kimura M, Demachi A, Sekine T, Yamamoto K, Shimizu N: Characterization of novel natural killer (NK)-cell and gammadelta T-cell lines established from primary lesions of nasal T/NK-cell lymphomas associated with the Epstein-Barr virus. Blood 2001, 97:708-713). Subsequently, we established two novel EBV-positive gammadelta T-cell lines from the peripheral blood of patients with chronic active EBV infection. Analysis of the terminal repeat of EBV showed that the three cell lines consisted of monoclonal populations, and flow cytometry showed that they had a common phenotype of gammadelta T cells: CD3(+) CD4(-) CD8(-) CD16(-) CD19(-) CD56(+) CD57(-) HLA-DR(+) T-cell receptor (TCR) alphabeta(-) TCR gammadelta(+). Analysis for the expression of TCR by flow cytometry showed that all three cell lines were Vgamma9(+)/Vdelta2(+), but negative for VgammaI, Vdelta1, or Vdelta3 TCR. Southern blot analysis for TCR genes showed that the three cell lines had a common rearrangement of Vgamma9-JgammaP and Jdelta3 genes. Polymerase chain reaction and sequence analysis of the junction between Vdelta and Jdelta genes revealed that the Jdelta3 genes were rearranged with the Vdelta2 genes. In contrast, none of the EBV-negative gammadelta T-cell lines, Molt-14, Peer, or Loucy, which were analyzed for controls, had Vgamma9 or Vdelta2 TCR, or a rearrangement of Jdelta3 genes. These results indicated that Vgamma9-JgammaP/Vdelta2-Jdelta3(+) gammadelta T cells were preferentially affected by EBV and expanded in patients with nasal gammadelta T-cell lymphoma and chronic active EBV infection. Jdelta3(+) gammadelta T cells are known to be a very minor population in gammadelta T cells of peripheral blood, whereas Vgamma9-JgammaP/Vdelta2-Jdelta1(+) cells are the major population. The close association of EBV with this particular gammadelta T-cell population may provide a key to the etiology of EBV-positive lymphoproliferative diseases.

Abstract
While Epstein-Barr virus (EBV) tropism in B cells and nasopharygeal epithelial cells in the normal host has been demonstrated, recently the role of its infection into non-B cell populations has been suggested to play a pivotal role in the pathogenesis of several EBV-related hematological as well as non-hematological diseases. Ectopic EBV infection in T cells or natural killer (NK) cells has been reported in EBV-associated hematological diseases, such as acute fulminant EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH) and chronic active EBV infection (CAEBV). Recent advances in the analysis of EBV infection in lymphocyte subpopulations have clarified the differential virus-cell interaction within these EBV-related disorders. EBV infection was predominantly found in CD8(+) T-cells from EBV-HLH, and in CD4(+) T-cells or NK cells from CAEBV, while the majority of EBV infected cells were found in B cells from acute infectious mononucleosis (IM). Different virus-cell interactions between acute EBV-HLH and CAEBV have indicated different pathogenic mechanisms against EBV infection between the two EBV-associated diseases, accounting for the difference in clinical manifestations between the two diseases.

Abstract
A 62-year-old Japanese man presented with high fever, cough, and sputa. Computed tomography (CT) scan of the chest revealed lung infiltrates with air bronchogram of the right middle lobe and mediastinal lymphadenopathy. Bronchoscopic examination was performed, and Mycobacterium avium complex was detected from bronchoalveolar lavage fluid. Although the administration of clarithromycin and levofloxacin improved the patient's symptoms, the lung infiltrates on chest CT scan gradually worsened. Lung biopsy of segments 4 and 8 by video-assisted thorachoscopy revealed angiocentric and angiodestructive massive lymphoplasmocytic infiltrations with multinucleated giant cells, which were compatible with grade II angiocentric immunoproliferative lesions. The patient was found to have deterioration of renal function, and glomerular filtration rate was 32.6 mL/min. His kidneys were enlarged and showed prominent and diffuse uptake of gallium-67 citrate. Percutaneous renal biopsy revealed massive infiltration of CD4+ mononuclear cells, plasma cells, and eosinophils in the interstitium and destruction of normal structure of tubules. Blood vessels were destroyed and replaced by inflammatory cells. The combination chemotherapy achieved a remission, and the patient has remained free of disease at 2 years after onset of the illness. We recommend the imaging of kidneys for diagnosis and following renal biopsy to evaluate the renal involvement of angiocentric immunoproliferative lesions.

Abstract
HV(MNE) is a novel Epstein-Barr (EBV)-like virus isolated from a Macaca nemestrina with CD8(+) T-cell mycosis fungoides-cutaneous T-cell lymphoma. Here it is demonstrated that intravenous inoculation of irradiated HV(MNE)-infected T cells or cell-free virus from the J94356(PBMC) cell line in New Zealand White rabbits results in seroconversion to the viral capsid antigen (VCA) of EBV; all animals that seroconverted to VCA developed malignant lymphoma within months of inoculation. In contrast, control rabbits, inoculated with heat-inactivated culture supernatants from the same cell line, failed to seroconvert to VCA and did not develop disease. Disseminated lymphoma cells of mixed origin were detected in most vital organs, including the spleen, liver, lungs, kidneys, and heart of the affected rabbits. Neoplastic infiltrates were also observed in lymph nodes, thymus, skin, and subcutaneous tissues. HV(MNE) DNA and EBV-like RNA expression was demonstrated in the lymphomatous organs and in 2 transformed T-cell lines, one established from the lymph node and the other from the blood of the 2 lymphomatous animals. Analysis of one of these T-cell lines demonstrated the persistence of HV(MNE) DNA, expression of an LMP1-like protein, and acquisition of interleukin-2 independence, and constitutive activation of the Jak/STAT pathway. Thus, HV(MNE) in rabbits provides a valuable animal model for human T-cell lymphoma whereby genetic determinants for T-cell transformation by this EBV-like animal virus can be studied.

Abstract
Lymphomatoid granulomatosis is a necrotizing angiocentric and angiodestructive infiltrative process involving primarily the lung, skin, central nervous system, and kidney. The incidence is highest in middle-aged men and is rare in children. We report a case of lymphomatoid granulomatosis involving both skin and lung in a 4-year-old boy. The disease progressed to peripheral T-cell lymphoma, which was unusual in light of recent evidence suggesting a B-cell origin in the majority of cases.

Abstract
This study describes the clinicopathologic features of 5 patients who developed a fulminant Epstein-Barr virus (EBV)-positive clonal T-cell lymphoproliferative disorder (LPD) after acute EBV infection. One additional patient developed a similar disorder in the setting of long-standing chronic active EBV infection. Detailed immunophenotyping, in situ hybridization for EBV early RNA-1 (EBER1) and polymerase chain reaction (PCR) analyses for immunoglobulin (Ig) heavy chain and T-cell receptor (TCR)-gamma gene rearrangements were performed on paraffin-embedded tissue from all patients. In addition, EBV strain typing and detection of the characteristic 30-bp deletion of the latent membrane protein-1 (LMP-1) gene were performed by PCR. Controls included 8 cases of uncomplicated infectious mononucleosis (IM). Patients included 4 males and 2 females with a median age of 18 years (2-37 years). Three patients were Mexican, 2 were white, and 1 was of Asian descent. All presented with fever, hepatosplenomegaly, and pancytopenia; 5 were previously healthy, but had a clinical history of a recent viral-like upper respiratory illness (1 week to 2 months), and 1 patient had documented chronic active EBV infection for 7 years. Serologic data for EBV were incomplete but titers were either negative or only modestly elevated in 3 cases. In 1 case serology was consistent with severe chronic active EBV infection. In the remaining 2 cases serologic studies were not performed. All patients died within 7 days to 8 months of presentation with T-cell LPD. On histologic examination, the liver and spleen showed prominent sinusoidal and portal lymphoid infiltrates of CD3+, βF1+, EBER1+ T cells lacking significant cytologic atypia. Two cases were CD4+, 2 cases were CD8+, and 2 cases had admixed CD4+ and CD8+ cells without clear subset predominance. All were TIA-1+, CD56−. Only rare B cells were noted. Marked erythrophagocytosis was present. Molecular analysis revealed identical T-cell clones in 2 or more sites (liver, spleen, lymph node) in 5 cases. All patients carried type A EBV; 4 cases had wild-type EBV-LMP, and 2 showed the 30-bp deletion. This fulminant T-cell LPD after acute/chronic EBV infection is characterized by hepatosplenomegaly, often without significant lymphadenopathy, fever, liver failure, pancytopenia, and erythrophagocytosis indicative of a hemophagocytic syndrome. EBV serology may be misleading, with lack of elevated titers. The presence of an EBER1+ T-cell infiltrate with scant B cells should alert one to this diagnosis. Although cytologic atypia is minimal, studies for T-cell clonality confirm the diagnosis.

Abstract
Lymphomatoid granulomatosis is currently classified as part of a spectrum of angiocentric immunoproliferative lesions. These were initially thought to be of T-cell phenotype, but recent papers have shown that some cases are B-cell proliferations, sometimes associated with Epstein-Barr virus infection. We reviewed the clinicopathological features of 16 patients with pulmonary lymphomatoid granulomatosis, using immunohistochemistry to assess the phenotype of the infiltrate, the polymerase chain reaction to look for immunoglobulin heavy chain and T-cell receptor gene rearrangements, and in-situ-hybridization to look for Epstein-Barr virus infection. In seven of seven cases the atypical lymphoid population was of B-cell phenotype, with four cases showing evidence of either monoclonality or oligoclonality. All seven cases, including those that lacked unequivocal proof of malignancy, behaved aggressively. Epstein-Barr virus RNA was detected in four cases. We conclude that some cases of lymphomatoid granulomatosis are B-cell lymphomas, sometimes associated with Epstein-Barr virus infection.
