BACKGROUND: Malaria is known to cause acute and deadly complications. However, malaria can cause unforeseen pathologies due to its chronicity. It increases the risk of endemic Burkitt Lymphoma development by inducing DNA damage in germinal centre (GC) B cells, and leading higher frequency of Epstein-Barr virus (EBV)-infected cells in GCs. EBV is well known for its tropism for B cells. However, less is known about EBV's interaction with T cells and its association with T cell lymphoma...

Dasatinib is currently approved for clinical use as a first-line treatment agent for newly diagnosed chronic myeloid leukemia (CML). However, only a few clinical trials have been performed to evaluate dasatinibinduced PE following first-line therapy. We investigated the incidence and clinical features of dasatinib-induced PE following first-line therapy in Japanese CML patients of real world clinical practice settings. Among 22 patients, the median age of PE-positive patients was higher than that of PE-negative patients...

Human enteropathy-associated T-cell lymphoma (EATL) is classified into 2 distinct subgroups based on their phenotypes (type I and type II). Canine intestinal T-cell lymphoma can be morphologically classified into large and small cell lymphomas (LCL and SCL, respectively). Their association with human EATL or immunohistochemical and biological features has not been well characterized. In this study, the immunohistochemical profiles of 17 cases of LCL and 33 cases of SCL were evaluated with markers used for human EATL classification...

Large granular lymphocyte (LGL) leukemia has been recognized in the World Health Organization classifications among mature T cell and natural killer cell neoplasms and is divided into three categories. Chronic T cell leukemia and natural killer cell lymphocytosis can be considered as a similar spectrum of an indolent disease characterized by cytopenias and autoimmune conditions. The last category, aggressive natural killer cell LGL leukemia is very rare, related to Epstein-Barr virus, and seen mainly in young Asian people...

Acquired pure red cell aplasia and acquired amegakaryocytic thrombocytopenic purpura are rare in children. Similarly, clonal expansion of T-cell large granular lymphocytes is infrequently seen in pediatrics. Lipopolysaccharide-responsive beige-like anchor (LRBA) protein deficiency is a recently described immunodeficiency syndrome that has been associated with inflammatory bowel disease and autoimmune phenomena such as Evans syndrome. Here, we describe a patient with LRBA deficiency who developed acquired pure red cell aplasia and acquired amegakaryocytic thrombocytopenic purpura associated with expansion of clonal T-cell large granular lymphocytes...

Malakoplakia is a rare chronic granulomatous disease that may affect many organs, including the lung, brain, adrenal glands, pancreas, bone, and the genitourinary tract. The gastrointestinal tract is the most common site of involvement outside of the urinary tract. Herein, we present a case of a 65-year-old male who presented with abdominal pain and unintentional weight loss. Physical examination findings were unremarkable, but colonoscopy revealed an isolated large, flat, soft, and pale lesion in the transverse colon...

Dasatinib induces lymphocytosis of large granular lymphocytes (LGLs) in a proportion of patients with chronic myelogenous leukemia (CML), and is associated with better clinical outcomes. LGLs consist of cytotoxic T lymphocytes and natural killer cells; however, the context and phenotypic/functional features of each type of LGL are unknown. To better define features of these LGLs, we investigated lymphocytosis in CML patients treated with dasatinib. D57-positive and CD4-positive type I T-helper (Th) cells (CD57+ Th cells) rarely occur in CML patients without lymphocytosis and in healthy individuals; however, a substantial increase in the proportion of CD57+ Th cells was observed in CML patients treated with dasatinib...

REVIEW
Domenico Ribatti, Roberto Tamma, Enrico Crivellato
Natural killer (NK) cells are large granular lymphocytes of the innate immune system, responsible for direct targeting and killing of both virally infected and transformed cells. Under pathological conditions and during inflammation, NK cells extravasate into the lymph nodes and accumulate at inflammatory or tumor sites. The activation of NK cells depends on an intricate balance between activating and inhibitory signals that determines if a target will be susceptible to NK-mediated lysis. Many experimental evidences indicate that NK cells are also involved in several immunoregulatory processes and have the ability to modulate the adaptive immune responses...

Large granular lymphocyte leukemia (LGL) are chronic lymphoproliferative disorders classified into three main groups: T-cell LGL leukemia (T-LGL), aggressive NK-cell leukemia and chronic lymphoproliferative disorder of NK cells (NK-LGL). Patients with LGL leukemia exhibit chronic (>3 months) and moderate (<1G/L) to substantial monoclonal expansion of large granular lymphocytes in the peripheral blood. Cytologically, large granular lymphocytes are medium to large cells which are further characterized by an eccentric nucleus and a slightly basophilic cytoplasm containing azurophilic granules...

T-cell large granular leukemia (T-LGL) is a rare lymphoproliferative disorder characterized by the clonal expansion of cytotoxic T lymphocytes. We present a unique case of T-LGL and concurrent retroperitoneal sarcoma occurring in a patient with long-standing rheumatoid arthritis. Pathology revealed a high-grade dedifferentiated liposarcoma. The diagnosis of T-LGL with a synchronous retroperitoneal sarcoma is a case that highlights the surgical management of these two rare conditions.

Most studies of immunosuppressive therapy (IST) in myelodysplastic syndromes (MDS) are limited by small numbers and their single-center nature, and report conflicting data regarding predictors for response to IST. We examined outcomes associated with IST and predictors of benefit in a large international cohort of patients with MDS. Data were collected from 15 centers in the United States and Europe. Responses, including red blood cell (RBC) transfusion independence (TI), were assessed based on the 2006 MDS International Working Group criteria, and overall survival (OS) was estimated by Kaplan-Meier methods...

We report five patients with human immunodeficiency virus-1/acquired immunodeficiency syndrome (HIV-1/AIDS) who developed T-cell large granular lymphocytic proliferation (T-LGLP) or leukemia (T-LGLL). None of the patients fulfilled criteria for diagnosis of diffuse infiltrative lymphocyte syndrome (DILS) or HIV-associated CD8+ lymphocytosis syndrome at the time of diagnosis of LGL. The immunophenotype of malignant T-cells was identical in three patients with co-expression of CD3, CD8, CD57, and T-cell receptor (TCR) alpha/beta...

Large granular lymphocytic leukemia (LGLL) is a chronic proliferation of cytotoxic lymphocytes in which over 70% of patients develop cytopenia(s) requiring therapy. LGLL includes T-cell LGLL (T-LGLL) and chronic lymphoproliferative disorder of NK-cells (CLPD-NK). The neoplastic cells in LGLL usually exhibit a single immunophenotype in a patient, with CD8-positive/αβ T-cell type being the most common, followed by NK-cell, γδ T-cell, and CD4-positive/αβ T-cell types. We investigated a total of 220 LGLL cases and identified 12 mixed-phenotype LGLLs (5%): 7 cases with coexistent αβ T-cell and NK-cell clones and 5 with coexistent αβ and γδ T-cell clones...

OBJECTIVE: Up to one third of patients with T-cell large granular lymphocyte leukemia (T-LGL-leukemia) display symptoms of rheumatoid arthritis (RA). In Crohn's disease and in psoriasis treatment with TNFα-inhibitors is associated with hepatosplenic γδT-cell-lymphoma and with clonal expansion of γδT-cells, respectively. Here, we determine the prevalence of clonal T-LGL cells in patients with RA and define risk factors for this rare hematologic malignancy. METHODS: 529 RA-patients were recruited between November, 2013 and August, 2015...

Hemophagocytic syndrome (HPS) is a clinicopathological entity characterized by histiocytic proliferation, with marked hemophagocytosis in the reticuloendothelial organs. HPS caused by lymphoma is termed lymphoma-associated hemophagocytic syndrome (LAHS), and there are few reports on canine and feline LAHS. The objective of this study was to examine the clinical, diagnostic, and clinicopathologic features of LAHS in six dogs. The diagnostic criteria of LAHS consisted of lymphoma, bicytopenia or pancytopenia in the blood, and increased hemophagocytosis in the reticuloendothelial organs...
