Abstract
Objective The correlation between laboratory indicators and clinical treatment effects and the prognosis of multiple myeloma remains poorly understood. Therefore, our study investigated whether serum IgG subclasses could be employed as potential indicators contributed to evaluate the therapeutic effect and prognosis of patients with multiple myeloma. Patients and Methods. Records of patients with multiple myeloma were initially diagnosed at the First Affiliated Hospital of Soochow University, China, from August 1, 2017, to February 28, 2020. The assessment abilities of serological indicators for therapeutic effect were evaluated in patients compared with healthy controls. Results In 560 study patients with multiple myeloma, serum IgA, IgG, IgM, κ-LC, and λ-LC increased by15%, 33.04%, 1.96%, 27.50%, and 26.43%, respectively. Further analysis found that IgG1, IgG2, IgG3, and IgG4 were over the upper limit of the reference range with 26.38%, 6.09%, 8.12%, and 4.64%, respectively. κ-LC and λ-LC were found in the urine in 65.13% and 29.70%, respectively. In peripheral blood, the proportion of CD3+CD4+, CD3−CD19+ cells, and CD4+/CD8+ decreased, whereas CD3+CD8+ cells and CD16+/CD56+ increased, and the associated cytokines IL-2, IL-4, IL-6, TNF-α, and IFN-γ were upregulated in patients when compared with healthy controls. Furthermore, the serum levels of IgA, IgG, IgG1, IgG2, IgG3, and IgG4 gradually decreased in patients before, during, and after treatment. Similar results were found in serum and urine κ-LC and λ-LC. Conclusion Serum IgG1 level could serve as the potential indicator for evaluating the therapeutic effect for patients with multiple myeloma. κ-LC and λ-LC also have the potential to be prognostic indicators. More studies are warranted to explore these serological indicators for personalized therapy in the future.

Abstract
A 5.25-year-old cynomolgus macaque (Macaca fascicularis) was found to have a marked leukocytosis due to a lymphocytosis on routine quarantine laboratory data prior to inclusion in a preclinical research study. The majority of lymphocytes were characterized as intermediate to large with round to convoluted nuclei, coarse to clumped chromatin, rare prominent nucleoli, and moderate amounts of lightly basophilic cytoplasm that frequently contained small magenta granules and/or clear vacuoles. The animal had tested negative for several viruses and other etiologic agents found in nonhuman primates 1 week prior to shipment to the research facility. However, further evaluation of the blood smear revealed rare hemoflagellates, and later testing using real-time PCR and ELISA was confirmatory for Trypanosoma cruzi (T cruzi). Trypanosoma cruzi is a zoonotic pathogen responsible for Chagas disease in people and can have negative consequences on study results when positive animals are inadvertently used for preclinical research. This case report describes a marked large granular lymphocytosis in an otherwise healthy macaque as the only indication of infection with T cruzi in an animal believed to be negative for the infection. Additionally, it highlights the diagnostic limitations of screening tests to rule out diseases in animals intended to be used in preclinical studies.

Abstract
Aims and Background Lymphoid malignancies expressing CD56 are rare and most occur in the nasal or nasopharyngeal region. They derive from natural killer ceils or from a small subset of T cells that have granular cytoplasm containing molecules that mediate cytotoxic activity: TIA-1, granzyme B and perforin. Both types are closely associated with Epstein-Barr virus. Methods We report the pathologic, immunophenotypic and molecular findings in 14 cases of nasopharyngeal/nasal type T/NK lymphomas. Results Clinically, all patients had localized disease and also had symptoms limited to the nose. The neoplastic cells were frequently pleomorphic, and angiocentric growth was common. Combined immunophenotypic and gene rearrangement analyses demonstrated that most of the cases were true NK cell tumors and were either CD56+ and CD3- or CD56+ and CD3+. Immunohistochemical study showed TIA-1 and granzyme B expression in all cases. By in situ hybridization, most of the cases were associated to Epstein-Barr virus, harboring type 1 virus, and polymerase chain reaction amplification across the 30 bp deletion showed high frequency of latent membrane protein-1-deleted variants. Conclusions The nasal type T/NK cell lymphoma shows distinctive clinicopathologic, immunophenotypic and molecular features. These results confirm the important role of Epstein-Barr virus as a local factor in their pathogenesis.

Abstract
Natural killer cell proliferation is an uncommon haematological disorder that has a number of different clinical manifestations. There have been only two prior reports linking this process with neurological disease, both reports describing peripheral neuropathy. We report the case of a young man presenting with a short history of lethargy, lower limb paraesthesia and marked weight loss who was found to have a natural killer cell lymphocytosis and features of both an autonomic and a peripheral neuropathy. The patient's clinical features responsed to a combination of cytotoxic and immunosuppressive therapy, and the patient is now clinically stable with mild ongoing lymphocytosis, diarrhoea and postural hypotension. We review the possible pathological link between natural killer cells and neurological disease.

Abstract
Atypical fibroxanthoma (AFX), a benign lesion, and pleomorphic malignant fibrous histiocytoma (MFH) are thought to represent points along the same neoplastic spectrum but with different prognoses and treatments. Diagnosis based on histology and clinical parameters alone is sometimes difficult, and a reliable cost-effective immunohistochemical marker to help distinguish these lesions would be beneficial. The diagnosis of AFX or MFH was based upon published clinical and microscopic criteria. Formalin-fixed, paraffin-embedded tissues of 17 cases of AFX and 26 cases of MFH were immunostained with monoclonal antibody to CD99. For all cases, CD99 expression was scored on a four-tiered scale: negative, weak (1+), moderate (2+), or strong (3+). Two pathologists blinded to tumor diagnoses and type of immunostain evaluated each case independently. The interobserver correlation coefficient was calculated. Seventeen patients with AFX (16 males and one female; mean age = 79) and 26 patients with MFH (16 males and 10 females; mean age = 60) were included. AFX lesions were from the head and the face, mean size = 1.5 cm, and MFH lesions were from the head, the neck, the trunk, and the upper/lower extremities, mean size = 5.2 cm. The 17 cases of AFX demonstrated moderate or strong (2 to 3+) immunoreactivity with CD99, compared to nine of 26 (35%) MFH cases (chi-square = 18.38; p < 0.001; interobserver correlation coefficient = 0.83). Of these, 16 of 17 (94%) AFX cases stained diffusely with CD99, while only four of 26 (15%) MFH cases stained diffusely. Control slides were adequate. Our study demonstrated that CD99 can help distinguish AFX from MFH, in addition to other immunohistochemistry as well as clinical and histologic criteria.

Abstract
We report 5 cases of Aggressive Natural Killer-Cell Leukemia (ANKL) diagnosed and treated in our institution within a period of 5 years. Presented are the clinical, hematological, immunophenotypic, immunogenotypic and cytogenetic data. ANKL is a very rare disorder. On review of the English-language literature only 68 published cases were identified. Analysis was performed on a total number of 73 cases (68 from the literature and the series of 5 presented hereby). Presented and discussed are the epidemiology, clinical picture, morphology, cell marker, immunogenotype, cytogenetics, and survival data of the analysis, as well as the associations with the Epstein-Barr virus (EBV). To our knowledge this is the largest series of cases of ANKL analyzed and therefore it is hoped to contribute towards a better characterization of the disorder.

Abstract
Indolent natural killer (NK) cell lymphoproliferative disorders include a heterogeneous group of patients in whom persistent expansions of mature, typically CD56(+), NK cells in the absence of any clonal marker are present in the peripheral blood. In the present study we report on the clinical, hematological, immunophenotypic, serological, and molecular features of a series of 26 patients with chronic large granular NK cell lymphocytosis, whose NK cells were either CD56(-) or expressed very low levels of CD56 (CD56(-/+dim) NK cells), in the context of an aberrant activation-related mature phenotype and proved to be monoclonal using the human androgen receptor gene polymerase chain reaction-based assay. As normal CD56(+) NK cells, CD56(-/+dim) NK cells were granzyme B(+), CD3(-), TCRalphabeta/gammadelta(-), CD5(-), CD28(-), CD11a(+bright), CD45RA(+bright), CD122(+), and CD25(-) and they showed variable and heterogeneous expression of both CD8 and CD57. Nevertheless, they displayed several unusual immunophenotypic features. Accordingly, besides being CD56(-/+dim), they were CD11b(-/+dim) (heterogeneous), CD7(-/+dim) (heterogeneous), CD2(+) (homogeneous), CD11c(+bright) (homogeneous), and CD38(-/+dim) (heterogeneous). Moreover, CD56(-/+dim) NK cells heterogeneously expressed HLA-DR. In that concerning the expression of killer receptors, CD56(-/+dim) NK cells showed bright and homogeneous CD94 expression, and dim and heterogeneous reactivity for CD161, whereas CD158a and NKB1 expression was variable. From the functional point of view, CD56(-/+dim) showed a typical Th1 pattern of cytokine production (interferon-gamma(+), tumor necrosis factor-alpha(+)). From the clinical point of view, these patients usually had an indolent clinical course, progression into a massive lymphocytosis with lung infiltration leading to death being observed in only one case. Despite this, they frequently had associated cytopenias as well as neoplastic diseases and/or viral infections. In summary, we describe a unique and homogeneous group of monoclonal chronic large granular NK cell lymphocytosis with an aberrant activation-related CD56(-/+dim)/CD11b(-/+dim) phenotype and an indolent clinical course, whose main clinical features are related to concomitant diseases.

Abstract
The majority of primary testicular lymphomas are of B-cell type. Other primary lymphomas are rarely encountered in the testes. Natural killer (NK)/T-cell lymphomas of nasal type are aggressive extranodal lymphomas associated with Epstein-Barr virus infection that are usually encountered in the upper aerodigestive tract. They also occur in the skin, soft tissue, and colon. Primary testicular NK/T-cell lymphomas are rarely reported. We describe the case of a 66-year-old Korean man who presented with right-sided painless testicular enlargement and underwent radical orchiectomy. Histologic examination revealed an angiocentric and angioinvasive infiltrate of medium to large tumor cells with moderately abundant pale pink cytoplasm and folded and indented pleomorphic nuclei. Paraffin immunohistochemical studies showed positivity of the tumor cells for CD45, TIA-1, granzyme B, CD56, and CD3 epsilon. In situ hybridization showed diffuse positivity for Epstein-Barr virus-encoding RNA. The results of gene rearrangement studies for the gamma chain of the T-cell receptor were negative. The results of paraffin immunohistochemical studies for CD20, CD8, CD45RO, beta f1, and ALK-1 were negative. An extensive workup showed no evidence of lymphoma outside the testes. We report a rare case of primary testicular NK/T-cell lymphoma of the nasal type of true NK-cell origin.

Abstract
Chronic natural killer cell lymphocytosis (CNKL) is characterized by greatly increased numbers of natural killer (NK) cells and patients with this disease may survive for long periods. This is in contrast to patients with leukemic proliferations of NK cells who can have a rapidly progressive clinical course. We identified a pediatric patient who was largely healthy who had CNKL and we sought to determine if the expanded CD16(+)CD3(-) population in this patient functions differently than classical NK cells. Cytotoxic activity against NK cell-sensitive K562 target cells was present, but lower than that in control donors when calculated as lytic units per CD16(+)CD3(-) cell. This cytolytic activity was inducible in patient samples by IL-2/IL-12 stimulation proportionately to that induced in samples from control donors. Intracellular perforin was also present and induced in patient CD16(+)CD3(-) cells similarly to controls. Other presumed NK cell activities, such as IL-2/IL-12 induced IFN-gamma expression and initiation of apoptosis evidenced by annexin V binding after CD16 crosslinking were present in patient samples. Patient CD16(+)CD3(-) cells, however, differed from classical NK cells, as the majority did not express CD56, CD57, CD8, or CD11b. Most convincingly, there was a 5 log decrease in CD11b expression in patient CD16(+)CD3(-) cells compared to control as determined by mean channel fluorescence. These observed differences may explain the relatively benign phenotype of this disorder.

Abstract
Natural killer (NK) cells provide anti-infectious, anti-neoplastic, and immunomodulatory function effected by both cytokine production and direct cellular cytotoxicity that is not major histocompatibility complex-restricted. NK cells lack truly specific cell surface determinants as well as antigen-specific receptors. Recent information suggests a variety of receptor-ligand interactions that underlie recognition and treatment of target cells by NK cells. Primary NK cell disorders in humans are currently classified into NK cell lymphomas and chronic NK cell lymphocytosis (CNKL). In this review, we summarize current understanding of the biology of NK cells and describe the clinical manifestations of CNKL.

Abstract
This review covers the diagnosis and management of natural killer and peripheral T-cell lymphomas (PTCL). Problems with PTCL include their rarity, representing usually 10-15% of non-Hodgkin's lymphomas in the Western Hemisphere, morphologic heterogeneity, and lack of immunophenotypic markers for clonality. Additionally, their clinical behavior is variable and may not correlate with morphology.
Dr. Kinney gives a general overview of the diagnosis of PTCL and NK cell neoplasms. Emphasis will be placed on extranodal T cell and natural killer (NK) cell lymphomas such as hepatosplenic lymphoma, subcutaneous panniculitis-like lymphoma and nasal/nasal type T/NK-cell lymphoma. The use of ALK gene regulation in the classification of anaplastic large cell lymphoma is also reviewed.
Dr. Loughran describes current understanding of the pathogenesis of large granular lymphocyte (LGL) leukemia. The discussion focuses on LGL leukemia as an instructive model of dysregulated apoptosis causing both malignant and autoimmune disease. Current management options and mechanisms of therapeutic response are also described.
Dr. Greer addresses whether PTCL should be treated differently from the more common diffuse large B cell lymphomas. He discusses the therapeutic options for anaplastic large cell lymphoma (ALCL), from a conservative approach for primary cutaneous ALCL to combination chemotherapy for the highly chemosensitive ALCL expressing anaplastic lymphoma kinase. He reviews therapy options for the extranodal subtypes of PTCL by drawing from series in adults, pediatrics, dermatology, and the Far East.

Abstract
Clinical, hematologic, and immunophenotypic data were studied in 25 dogs with large granular lymphocyte (LGL) lymphocytosis. Primarily large-breed dogs were affected, with an average age at initial diagnosis of 10 years (range 5-14 years). All dogs had persistent (>4 months) LGL lymphocytosis except for three that were euthanized with aggressive disease. Splenomegaly was reported in 12 of 20 dogs in which splenic size was evaluated. The clinical course was heterogeneous and dogs were divided into four groups based on similar clinical and hematologic findings: acute leukemia (3/25), persistent lymphocytosis with anemia (12/25), persistent lymphocytosis without anemia (8/25), and reactive lymphocytosis (2/25). Immunophenotypes varied within groups but were homogeneous among cells from the same patient except in the two dogs classified as reactive LGL lymphocytosis. Analysis of T-cell receptor (TCR) usage identified three main LGL lineages. TCRalphabeta was expressed in 15/25 (60%) cases. TCRgammadelta was expressed in 8/25 (32%) cases, and 2/25 (8%) cases were CD3-, compatible with NK cells. beta2 integrin expression was distinctive. CD11a was consistently expressed, while CD11b was absent. CD11c was expressed only weakly in 16/25 (64%) cases. The leukointegrin alphadbeta2 was highly prevalent on all LGL lineages, being expressed in 23/25 (92%) cases. Prominent involvement of the spleen, relative sparing of bone marrow, an unexpectedly large proportion of gammadelta T-cell LGLs, and the distinctive beta2 integrin expression pattern on diverse lineages of LGLs suggest the disease arises from unique populations of lymphocytes that preferentially localize in the splenic red pulp.

Abstract
Interleukin (IL)-10, a product of T helper 2 (Th2) lymphocytes, has been shown to be an important regulator of lymphoid and myeloid cells, inhibiting mitogen, peptide and alloantigen-induced T-cell proliferation and IL-2 production. The microenvironment at the time of cell activation, notably the presence or absence of cytokines such as IL-10, interferon-gamma (IFN-gamma) and IL-2, is believed to determine the lineage and magnitude of cell-mediated responses. In this study, we show that recombinant human IL-10 (rhIL-10) exerts a dose-dependent inhibitory effect on human peripheral blood mononuclear cells stimulated in vitro, when these cells have not previously been exposed to rhIL-10. Furthermore, incubation of these cells with high doses of rhIL-10, either before or at the time of activation, results in inhibition which is followed several days later by the emergence of a population of CD8 positive cells. This rhIL-10-responsive CD8, positive cell population still emerges even when the cells are washed following incubation with rhIL-10 prior to cell activation. Using purified CD8 populations this was shown to be a direct action of rhIL-10 on CD8 cells and not via CD4 positive cells and monocytes. This finding was only observed when cells were activated with a cross-linking anti-CD3 antibody and not when activated with phorbol-12-mystrate-13-acetate (PMA) and calcium ionophore (CaIon), suggesting that the effect is mediated through cell-surface receptors. Analysis of CD8 positive clones reveal production of Tc2 patterns of cytokines and reduced cell cytotoxicity to allogeneic, natural killer and lymphokine activated cell targets.

Abstract
Chronic natural killer cell lymphocytosis is a persistent state of natural killer (NK) cell (CD3-CD16/CD56+) excess in the peripheral blood that is not associated with clinical lymphoma. In 16 consecutive patients (median age 60.5 years, range 7-77), males were overrepresented (M:F 7:1) and the median absolute NK cell count was 4.09 x 10(9)/l (range 1.2-16.6). Bone marrow examination was performed in 14 patients and showed atypical granulomata in two; chromosome studies in seven patients were normal. Clonal T-cell receptor gene rearrangement was not found in any of 12 patients evaluated. At presentation, seven patients (44%) had no clinical symptoms or signs and the others had vasculitic skin lesions (three patients), non-neutropenic fever (three patients), recurrent neutropenic infection (two patients), musculoskeletal symptoms (two patients), peripheral neuropathy (two patients), aphthous ulcers (one patient), and splenomegaly (one patient). Five patients had anaemia, five had neutropenia, and two had thrombocytopenia. After a median follow-up of 5.1 years (range 0-10.2) from immunophenotypic diagnosis or 5.7 years (range 0.1-14.1) from documentation of absolute lymphocytosis, vasculitic glomerulonephritis developed in one patient, accelerated splenomegaly developed in a patient receiving myeloid growth factor treatment, and severe aplastic anaemia developed in one patient. Treatment with nonsteroidal anti-inflammatory drugs or immunosuppressive agents was variably successful.

Abstract
Abstract
Expression of the natural killer (NK) cell antigen CD56 is uncommon among lymphomas, and those that do are almost exclusively of non–B-cell lineage and show a predilection for the nasal and nasopharyngeal region. This study analyzes 49 cases of nonnasal CD56+ lymphomas, the largest series to date, to characterize the clinicopathologic spectrum of these rare neoplasms. All patients were Chinese. Four categories could be delineated. (1) Nasal-type NK/T cell lymphoma (n = 34) patients were adults 21 to 76 years of age (median, 50 years), including 25 men and 9 women. They presented with extranodal disease, usually in multiple sites. The commonest sites of involvement were skin, upper aerodigestive tract, testis, soft tissue, gastrointestinal tract, and spleen. Only 7 cases (21%) apparently had stage I disease. The neoplastic cells were often pleomorphic, with irregular nuclei and granular chromatin, and angiocentric growth was common. The characteristic immunophenotype was CD2+ CD3/Leu4− CD3ε+ CD56+, and 32 cases (94%) harbored Epstein-Barr virus (EBV). Follow-up information was available in 29 cases: 24 died at a median of 3.5 months; 3 were alive with relapse at 5 months to 2.5 years; and 2 were alive and well at 3 and 5 years, respectively. (2) Aggressive NK cell leukemia/lymphoma (n = 5) patients presented with hepatomegaly and blood/marrow involvement, sometimes accompanied by splenomegaly or lymphadenopathy. The neoplastic cells often had round nuclei and azurophilic granules in the pale cytoplasm. All cases exhibited an immunophenotype of CD2+ CD3/Leu4− CD56+ CD16− CD57− and all were EBV+. All of these patients died within 6 weeks. (3) In blastoid NK cell lymphoma (n = 2), the lymphoma cells resembled those of lymphoblastic or myeloid leukemia. One case studied for CD2 was negative and both cases were EBV−. One patient was alive with disease at 10 months and one was a recent case. (4) Other specific lymphoma types with CD56 expression (n = 8) included one case each of hepatosplenic γδ T-cell lymphoma and S100 protein+ T-cell lymphoproliferative disease and two cases each of T-chronic lymphocytic/prolymphocytic leukemia, lymphoblastic lymphoma, and true histiocytic lymphoma. All of these cases were EBV−. Six patients died at a median of 6.5 months. Nonnasal CD56+ lymphomas are heterogeneous, but all pursue a highly aggressive clinical course. The nasal-type NK/T-cell lymphoma and aggressive NK cell leukemia/lymphoma show distinctive clinicopathologic features and a very strong association with EBV. Blastoid NK cell lymphoma appears to be a different entity and shows no association with EBV.

Abstract
Lymphoproliferative disorder of natural killer cells is a heterogeneous disorder, and an association with Epstein-Barr virus (EBV) is suggested in some cases. A Japanese male presenting with recurrent nasopharyngeal problems developed fever, generalized lymphadenopathy, and hepatosplenomegaly. Separated cells from lymph nodes were shown to have a natural killer (NK) cell, CD2(+), CD3(-), CD16(+), CD56(+), HLA-DR(+) phenotype. A progressive abnormality of hepatic function was associated with hepatorenal failure and death. A serologic study suggested reactivated EBV infection. In situ hybridization (ISH) studies showed Epstein-Barr virus-encoded RNA (EBER)-1 in lymph nodes, with lymphocytes infiltrating the liver and tissue from ethmoid sinus surgery 3 years prior to development of obvious lymphoproliferative disease. Polymerase chain reaction performed on lymph node DNA, using oligonucleotide primers specific for the EBV lymphocyte-determined membrane antigen (LYDMA) gene, revealed a single band, suggesting monoclonal proliferation of the tumor. NK activities of the lymphocytes from the lymph node and peripheral blood were markedly decreased. These findings suggest a close relationship between EBV infection and development of NK cell lymphoproliferative disorder.

Abstract
Expansion of the natural killer (NK) subset of lymphocytes represents a rare leukemia phenotype with variations in clinical presentation, morphology, surface phenotype, and effector function. This paper reports on a 5-year-old male patient who had an unusual presentation of an NK cell leukemia that was initially diagnosed as neuroblastoma. A bone marrow (BM) aspirate showed clumps of undifferentiated cells with the following phenotype: CD56bright+, CD33dim+, CD45-, CD2-, CD19-, CD16-, and CD57-. Cytochemistry was noncontributory. The patient, having failed to respond to conventional neuroblastoma chemotherapy, was subsequently diagnosed as having NK cell leukemia based on functional in vitro assays. The patient responded to acute lymphoblastic leukemia (ALL) chemotherapy but relapsed 4 weeks into treatment and eventually died 25 weeks after initial presentation. The cell surface phenotype observed is consistent with a rare NK cell subset, the biology of which has not been well defined. Freshly isolated BM cells killed K562 cells in a conventional 51Cr-release assay. Both interleukin-2 (IL-2) and interferon-alpha (IFN-alpha) induced LAK activity against the Daudi cell line. IL-2 induced proliferation of the leukemic cells. TNF-alpha, IFN-gamma, IL-6, IL-1ra, and TGF-beta levels were assessed and found to be concentrated in BM, in contrast to plasma samples. TNF-alpha was present at a high concentration in BM (150.9 pg/ml), probably a reflection of the associated disease pathology of severe bone pain and pyrexia. In summary, this paper details clinical and laboratory investigations of a leukemia of a rare NK cell subset.

Abstract
BACKGROUND A 63-year-old male presented with fever, a subcutaneous nodule, gingival hypertrophy, lacrimal gland enlargement, and no lymphadenopathy or hepatosplenomegaly, but had anemia, thrombocytopenia, and peripheral blood (PB) plus bone marrow (BM) involvement by leukemic cells. There was minimal response to multiagent chemotherapy and local radiotherapy, with a survival of 6.5 months from disease diagnosis. METHODS The PB and/or BM leukemic cells were evaluated using electron microscopy (EM), immunohistochemistry, flow-cytometric immunophenotyping, cytochemistry, cytogenetics, Southern blot analysis for gene rearrangement and Epstein-Barr virus (EBV), polymerase chain reaction for EBV and human herpes virus-6 (HHV-6), and in vitro culturing with inducing agents. RESULTS The leukemic cells were agranular and monocytoid, with a hairy cell-like bone marrow biopsy infiltrate. Myeloperoxidase (MPO) and alpha-naphthyl butyrate esterase staining was negative, and periodic acid-Schiff staining was positive by light microscopy. Electron microscopy showed MPO negativity and a lack of parallel tubular arrays. The immunophenotype was CD3-, CD56+, CD4+, CD8-, CD15+, TCR1-, and TCR2-, with germline immunoglobulin and T-cell receptor genes and an abnormal karyotype (44XY, 5q-, -13, 13q+, -15). No genomic material for EBV or HHV-6 was detected. Cell cultures with butyrate and N,N-hexamethylene bis-acetamide suggested the possible induction of tumor cells to express a T-cell immunophenotype. CONCLUSION A case of clonal acute natural killer (NK) cell leukemia with an unusual morphology (agranular) and unique phenotype (CD3-, CD56+, CD4+, CD15+) is presented. Unlike as in other acute NK leukemias, EBV was negative; there was no evidence of HHV-6. The tumor cell, after culturing with differentiating agents, may have been induced to express a T-cell immunophenotype.

Abstract
The human T-cell leukemia virus type I Tax protein trans-activates several cellular genes implicated in T-cell replication and activation. To investigate its leukemogenic potential, Tax was targeted to the mature T-lymphocyte compartment in transgenic mice by using the human granzyme B promoter. These mice developed large granular lymphocytic leukemia, demonstrating that expression of Tax in the lymphocyte compartment is sufficient for the development of leukemia. Furthermore, these observations suggest that human T-cell leukemia virus infection may be involved in the development of large granular lymphocytic leukemia.

Abstract
NK cells from three donors with a NK (CD3- CD56+ CD16+) lymphocytosis of unknown aetiology showed differential expression of CD45R0, an isoform of CD45 not expressed by NK cells from normal donors unless stimulated to proliferate in vitro. For donor FC, 60% of NK cells expressed CD45R0 over a 16 month period during which there was a partial resolution of the NK lymphocytosis. For donor SW, 37% of NK cells expressed CD45R0, increasing to 87% over a 14 month period during which the NK lymphocytosis increased. For donor RN few if any NK cells expressed CD45R0. After in vitro proliferation, 100% of NK cells generated from all donors expressed CD45R0. For donors FC and SW, CD45R0 remained expressed on more than 90% of cells at 3-4 weeks following cessation of proliferation. By contrast CD45R0 expression was gradually lost during long-term culture of NK cells from donor RN, with 58% of NK cells regaining the pre-culture CD45R0- phenotype. NK cells from normal donors also varied in the extent to which activation acquired CD45R0 was lost during long-term culture. The results obtained are consistent with the notion that NK cells from the NK lymphocytosis donors studied have previously undergone proliferation in vivo.

Abstract
We describe the first case of an Epstein-Barr virus (EBV)-associated natural killer-large granular lymphocyte (NK-LGL) leukemia in the United States to the best of our knowledge. A 29-year-old woman of Japanese descent developed EBV infection after a blood transfusion as indicated by a rise in serum antibody titers. Peripheral blood and bone marrow aspirate smears demonstrated increased LGLs. Flow cytometry showed that these cells expressed NK-associated surface antigens. Cytogenetic analysis of the bone marrow aspirate showed two distinct but related clones with multiple copies of a modified 7 marker chromosome. Death followed colonic perforation. Findings at necropsy included bone marrow lymphocytosis and erythrophagocytosis, a mononucleosis-like lymphadenitis, atypical hepatitis with a mixed, predominantly T-cell infiltrate, interstitial pneumonitis, and multiorgan system vasculitis with perforation of the transverse colon. Epstein-Barr virus transcripts were identified in lymphocytes infiltrating liver and peripheral nerve by in situ hybridization. In addition, Southern blot analyses showed monoclonal bands superimposed on oligoclonal ladders of EBV termini in liver and lymph node. The identical episomal form of EBV was found in the bone marrow, lymph node, and liver. No immunoglobulin (Ig), T-cell receptor beta, or T-cell receptor gamma chain gene rearrangements were identified. These studies support the hypothesis that the LGL population was a neoplastic EBV-related clonal proliferation of NK cells.

Abstract
BACKGROUND Chronic lymphoproliferative disorders are considered rare in Oriental patients and are thought to constitute only 2% of all leukemias in these patients, compared to 20-30% in Western patients. We conducted a retrospective analysis of Chinese patients with chronic lymphoproliferative disorders to define the frequency and spectrum of these disorders. METHODS A consecutive series of Chinese patients with leukemia and lymphoproliferative disorders seen at two regional hospitals in Hong Kong were analyzed retrospectively. The diagnosis of chronic lymphoproliferative disorders was based on morphologic and immunologic criteria proposed by the French-American-British Cooperative Study Group. RESULTS Sixty-four Chinese patients with chronic lymphoproliferative disorders were identified, and these patients constituted 19% of a total of 342 cases of leukemia diagnosed in 3 years. Chronic lymphocytic leukemia was the most common form, occurring at a frequency of 12.5% of all leukemias. The clinicopathologic features of these patients were similar to those of Western patients, except that Chinese patients tended to present with more advanced (Rai's Stages III and IV; Binet's Stage C) and bulky (splenomegaly > 9 cm) disease, and expressed lambda light chain about six times more frequently. Other chronic lymphoproliferative disorders identified in this study included prolymphocytic leukemia, mantle zone lymphoma, hairy cell leukemia, splenic lymphoma with villous lymphocytes, large granular lymphocyte leukemia, and Sezary syndrome. The authors did not identify any case of human T-cell lymphotropic virus-I-related lymphoproliferative disorders within the study period. CONCLUSION In addition to providing the frequencies of various chronic lymphoproliferative disorders in southern Chinese people, this study also showed that these disorders no longer should be considered rare in this population. Inherent biologic differences between lymphoproliferative disorders in Chinese and Western patients also may exist.

Abstract
An 18-year-old man was admitted to our hospital with high temperature and dyspnea. A chest radiograph revealed the presence of multiple round nodules compatible with a metastatic lung cancer. The peripheral white blood cell count was 22,000/mm3 and more than 85 percent were atypical large lymphocytes with azurophilic granules. He was diagnosed as having natural killer (NK)-cell granular lymphocyte proliferative disorder (NK-GLPD) as the lymphocytes were positive with CD56, a cell surface marker characteristic for NK cells. The major pathologic finding of the tissue collected from the pulmonary nodules by transbronchial lung biopsy was infiltration of mostly large granular lymphocytes.

Abstract
Lymphoproliferative disorders of granular lymphocytes (LDGL) represent a family of diseases characterized by persistent granular lymphocytosis with variable prognosis. The Epstein-Barr virus (EBV) has been occasionally linked with the development of LDGL. However, cutaneous manifestations of LDGL have rarely been reported. One patient had cutaneous vasculitis for 10 years before a definite diagnosis of LDGL was made. Chronic EBV infection was documented serologically and EBV DNA was detected in the peripheral blood lymphocytes. EBV RNA was detected in the nuclei of infiltrating lymphoid cells expressing CD43 in a skin biopsy specimen. A cytogenetic study showed clonal chromosomal abnormalities. This is the first report of EBV-associated LDGL of natural killer cells with cutaneous manifestations.

Abstract
HTLV-II has been associated with a variety of lymphoproliferative disorders, including atypical hairy cell leukemia, chronic T cell leukemia, T prolymphocytic leukemia, and large granular lymphocytic leukemia. However, a direct or indirect role for HTLV-II in these disorders is not yet firmly established. We studied a patient diagnosed as having leukemia of the large granular lymphocyte (LGL) type who was HTLV-II seropositive, to determine if the expanded cell population was infected. Two populations of CD3-CD16+ LGL were identified; one was CD8+, the other CD8-. Populations of cells with these surface markers as well as normal CD3+CD4+ and CD3+CD8+ cells were separated by flow cytometric methods, DNA extracted, and gene regions of HTLV-II pol and tax amplified, using the polymerase chain reaction, and probed after Southern blotting. HTLV-II was detected in the CD3+CD8+ population, and not in the CD3-CD16+ large granular lymphocyte population. This finding indicates that the role of HTLV-II, if any, in LGL proliferation is indirect.
