SEE HOHLFELD AND SCHULZE-KOOPS DOI101093/BRAIN/AWW053 FOR A SCIENTIFIC COMMENTARY ON THIS ARTICLE: Inclusion body myositis and T cell large granular lymphocytic leukaemia are rare diseases involving pathogenic cytotoxic CD8+ T cells. After encountering four patients with both disorders, we prospectively screened 38 patients with inclusion body myositis for the presence of expanded large granular lymphocyte populations by standard clinical laboratory methods (flow cytometry, examination of blood smears, and T cell receptor gene rearrangements), and performed muscle immunohistochemistry for CD8, CD57, and TIA1...

BACKGROUND: T-cell large granular lymphocytic leukaemia (T-LGL) is a lymphoproliferative disease that presents with immune-mediated cytopenias and is characterised by clonal expansion of cytotoxic CD3+ CD8+ lymphocytes. Use of methotrexate, ciclosporin, or cyclophosphamide as first therapy improves cytopenias in 50% of patients, but long-term use of these can lead to toxicity. We aimed to explore the activity and safety of alemtuzumab, an anti-CD52 monoclonal antibody, in patients with T-LGL...

Peripheral expansion of cytotoxic T lymphocytes (CTL) derived from the graft in the initial stages of allogeneic haematopoietic stem cell transplantation (alloHSCT) immune recovery is a well-known physiological event. The description of symptomatic large granular lymphocyte leukaemia in this setting may generate uncertainty, mostly in those cases in which the CTL expansion (CTLe) persists beyond the early transplantation period. We aimed to assess the nature of CTLe during the post-alloHSCT period in 154 adult patients with a long-term surveillance...

Large granular lymphocytic (LGL) leukaemia is an uncommon clonal lymphoproliferative disorder. The WHO classification recognizes three distinct disorders of LGLs: T-cell large granular lymphocytic leukaemia (T-LGL), chronic lymphoproliferative disorders of NK-cells (CLPD-NK) and aggressive NK-cell leukaemia. Despite the different origin of cells, there is considerable overlap between T-LGL and CLPD-NK in terms of clinical presentation and treatment. Majority of these patients are asymptomatic and may not need treatment...

Jason K W Chow, T K Chan
Three patients with pure red cell aplasia, with or without co-existing large granular lymphocytic leukaemia, who remained transfusion-dependent despite treatment with established first-line therapy, were treated with low-dose subcutaneous alemtuzumab 15 mg twice to thrice per week, for 3 to 4 weeks. The mean response time was 17 days compared with a response time of at least 61 days on standard first-line therapy. There were no serious side-effects and the mean duration of remission was 13 months. Low-dose subcutaneous alemtuzumab is a safe and effective treatment for pure red cell aplasia and further trials should be conducted to compare the long-term effectiveness of this treatment with conventional therapy...

Rarer chronic lymphoid leukaemias represent a challenge to the clinicians due to the limited information on their pathogenesis, difficulties on setting up prospective clinical trials and to their refractoriness to drugs used in the most common form of chronic lymphocytic leukaemia (CLL). In this review all these issues are addressed in three B-cell leukaemias: B-cell prolymphocytic leukaemia (B-PLL), hairy cell leukaemia (HCL) and HCL-variant and three T-cell leukaemias: T-cell prolymphocytic leukaemia (T-PLL), T-cell large granular lymphocytic leukaemia (T-cell LGLL) and adult T-cell leukaemia lymphoma (ATLL)...

AIMS: We describe a new rabbit monoclonal antibody, raised against a fixation-resistant epitope of the transcription regulator LIM domain only 2 (LMO2). METHODS AND RESULTS: Lymphoma cell lines and a large series of normal and neoplastic samples were investigated by Western blot and immunohistochemistry. The antibody detected nuclear positivity for the protein, with the exception of a proportion of classical Hodgkin lymphomas (HLs), peripheral T cell lymphomas (PTCLs) and solid tumours that showed granular cytoplasmic staining...

T cell and natural killer (NK)/T-cell neoplasms are rare and may occasionally present as leukaemia. We retrospectively searched T cell and NK/T-cell tumours in a single institution in Taiwan from January 2000 to December 2009 and identified 137 (19.1%) patients with T cell and NK/T-cell tumours among 718 patients with lymphoid neoplasms. Among these 137 patients, 18 (13.1%) presented with leukaemia including T-lymphoblastic lymphoma/leukaemia (T-LBL), T-cell prolymphocytic leukaemia, aggressive NK-cell leukaemia, adult T-cell lymphoma/leukaemia (ATLL), T-cell large granular lymphocytic (T-LGL) leukaemia and unspecified peripheral T-cell lymphoma...

Four women and three men after allogeneic (n=4) and autologous (n=3) haematopoietic SCT (HSCT) were observed to have an increase in T-cell large granular lymphocytes (T-LGLs) of CD3+CD8+ phenotype for a median of 41 (15-118) months. Clonal rearrangement of the T-cell receptor gene was verified by two PCR techniques and direct DNA sequencing, confirming that the cases were neoplastic and therefore classifiable as T-LGL leukaemia. In the allogeneic HSCT cases, T-LGL leukaemia was derived from donor T cells in three patients, as shown by DNA chimerism analysis, and recipient T cells in one patient who had graft failure previously...

AIMS: Extranodal natural killer (NK)/T-cell lymphoma (NKTL), comprising nasal NKTL and extranasal NKTL (ENKTL), is associated with Epstein-Barr virus (EBV). A bimodal age distribution was noted in NKTL patients. We examined the clinicopathological differences between two age groups of ENKTL patients (n = 23) and compared the findings with those of aggressive NK cell leukaemia (ANKL; n = 10) and monoclonal chronic active EBV infection-associated T/NK-cell lymphoproliferative disorders [chronic active EBV infection/TNK-lymphoproliferative disorders (CAEBV/TNK-LPD)] of NK-cell type (n = 45)...

Natural killer (NK) cell neoplasms, which include extra-nodal NK/T-cell lymphoma (nasal and extra-nasal) and aggressive NK cell leukaemia, are generally rare, but they are more common in people of Oriental, Mexican and South American descent. These neoplasms are highly aggressive, and show a strong association with Epstein-Barr virus. Aggressive NK cell leukaemia affects younger patients, who present with poor general condition, fever, and disseminated disease; they often die within a short time from systemic disease or complications such as multi-organ failure...

AIMS: T cell large granular lymphocytes (T-LGLs) are commonly increased in reactive conditions as well as T-LGL leukaemia. This differential diagnosis often requires a combined assessment of clonality and tumour burden. In this study we assessed the utility of flow cytometric (FC) analysis of T cell receptor beta chain variable region (TCR-Vbeta) expression by using 24 antibodies reactive to 70% of the TCR-Vbeta repertoire. METHODS: Analyses were performed on peripheral blood samples obtained from 20 patients with a confirmed diagnosis of T-LGL leukaemia and 18 patients without known T cell lymphoproliferative diseases...

The leucocytes of the blood of normal individuals and of patients showing a marked polymorphonuclear leucocytosis contain enzymes capable of digesting coagulated blood serum in neutral, alkaline or acid solutions. The cells in pus that is composed principally of polymorphonuclear leucocytes and the leucocytes of the circulating blood in myelogeneous leukaemia contain similar proteolytic enzymes, which act best when the reaction is alkaline. The leucocytes of the circulating blood and of the enlarged lymph nodes from a case of large cell, acute, lymphatic leukaemia contain proteolytic enzymes that act qualitatively in much the same way as the leucocytes of pus and as the white corpuscles of the blood in myelogenous leukaemia...

Large granular lymphocytes (LGL) leukaemia can arise from either natural killer (NK) cells or cytotoxic T lymphocytes (CTL). The T-cell form of LGL leukaemia has significant overlap with other haematological disorders and autoimmune diseases. Here we provide an overview of LGL biology. We also focus discussion on the indolent LGL leukaemia related disorders and their causal relationships. We then discuss the potential relationships and distinctions between indolent LGL leukaemia and non-malignant clonal lymphocyte expansion that occur in otherwise healthy individuals, especially elder people...

BACKGROUND: Large granular lymphocytic leukaemia (LGL-leukaemia) is considered a rare disease. LGL-leukaemia is usually of the T-cell type, but a minority displays an NK-cell phenotype. Incidence and prevalence are unknown. MATERIAL AND METHODS: We identified patients with LGL-leukaemia (with well-defined diagnostic criteria) diagnosed at Rikshospitalet University Hospital between 01.10.2001 and 31.12.2007. Their medical records were assessed retrospectively. RESULTS: LGL-leukaemia was diagnosed in 52 patients, 26 women and 26 men, median age of 59 (26 - 86) years, during the study period...

A 39-year-old man presented with a rapidly growing unilateral painless nodule on the right cheek. Histopathological examination and peripheral blood analysis both showed a population of T-cell large granular lymphocytes, which were CD1+, CD2+, CD5+, CD7+ and CD16+, with expression of cutaneous lymphocyte-associated antigen. Further laboratory examination revealed severe neutropaenia, relative lymphocytosis and a clonally rearranged T-cell receptor. The cutaneous manifestation of T-cell large granular lymphocytic leukaemia is very rare...

Fluorine-18 fluorodeoxyglucose (FDG)-positron emission tomography (PET) is useful in Hodgkin and B-cell lymphomas. Few data exist on T-cell and natural killer (NK)-cell lymphomas. Thirty consecutive T-cell and NK-cell lymphomas were investigated with PET-computerized tomography (CT). In 12 NK-cell lymphomas, all nasal/extranasal lesions were FDG-avid. In nasal/maxillary areas, FDG-avid tumours were consistently more localised than on CT, suggesting that soft tissue masses on CT were partly due to inflammation...
