  • [Title] Recurrent numerical aberrations of JAK2 and deregulation of the JAK2-STAT cascade in lymphomas.
  • The presence of JAK2 mutations in lymphomas has been addressed in larger cohorts, but there are little systemic data on numerical and structural JAK2 aberrations in lymphoid neoplasms.
  • To study the molecular epidemiology of these aberrations and the consecutive activation of the JAK2-STAT pathway in lymphomas, we examined 527 cases, covering the most common entities, in a tissue microarray by fluorescent in situ hybridization with breakable JAK2 probes, and immunohistochemistry for phosphorylated JAK2 (pJAK2) and its preferred downstream pSTAT3 and pSTAT5.
  • 9p24 gains were detected in 6/17 (35%) primary mediastinal B-cell lymphomas (PMBCLs), 25/77 (33%) Hodgkin's lymphomas (HLs), 3/16 (19%) angioimmunoblastic T-cell lymphomas (AILTs) and 1/5 ALK1(+) anaplastic large cell lymphomas (ALCLs); breaks were observed only in three cases. pJAK2 expression was most prevalent in PMBCL, peripheral T-cell lymphomas and HL. pSTAT3 predominated in ALCLs, HLs, AILTs, PMBCLs and peripheral T-cell lymphomas. pSTAT5 expression was detected frequently in follicular lymphomas, diffuse large B-cell lymphomas and AILTs.
  • In follicular lymphomas, concomitant expression of pJAK2 and pSTAT5 was linked to better prognosis, whereas expression of pSTAT3 in nongerminal center-like diffuse large B-cell lymphomas could identify a patient group with an inferior outcome.
  • Our findings stress that despite the rarity of activating JAK2 mutations in lymphomas, JAK2 is recurrently targeted by numerical, and rarely by structural, genetic aberrations in distinct lymphoma subtypes and that JAK2-STAT pathway may play a role in lymphomagenesis.

  • [Title] Variable CD52 expression in mature T cell and NK cell malignancies: implications for alemtuzumab therapy.
  • The anti-CD52 antibody alemtuzumab has been explored as a novel targeted therapy in T cell malignancies.
  • To assess the suitability of alemtuzumab therapy, we carried out a comprehensive study of CD52 expression using flow cytometry (FC) in 78 untreated patients diagnosed with mature T/natural killer (NK) cell neoplasms, including 34 adult T cell leukaemia/lymphomas (ATLL), two anaplastic large cell lymphomas (ALCL), three angioimmunoblastic T cell lymphomas (AITL), 16 cutaneous T cell lymphomas (CTCL), four extra-nodal T/NK cell lymphomas (ENT/NKCL), four hepatosplenic T cell lymphomas (HSTCL), 13 peripheral T cell lymphomas, not otherwise specified (PTCL-NOS) and two T-prolymphocytic leukaemia (T-PLL).
  • All AITL, HSTCL and T-PLL cases were CD52-positive and the frequency of CD52 expression was high in PTCL-NOS (92.3%), ATLL (94.1%) and CTCL (87.5%), implying a rational role for alemtuzumab in the treatment of these diseases; however, CD52 expression was low in ALCL (50%) and ENT/NKCL (25%).
  • FC testing for cell surface expression of CD52 is indicated in patients with T/NK cell malignancies being considered for alemtuzumab therapy.

  • [Title] Comparison of peripheral T-cell lymphomas and diffuse large B-cell lymphoma.
  • BACKGROUND: Peripheral T-cell lymphomas (PTCLs) are a biologically heterogeneous subgroup of lymphomas with poor prognosis.
  • In this study, the authors analyzed the clinical behaviors of PTCLs and diffuse large B-cell lymphoma (DLBCL).
  • METHODS: The authors compared the characteristics and outcomes of 59 patients with PTCLs, including 33 angioimmunoblastic T-cell lymphomas and 26 unspecified peripheral T-cell lymphomas, with the characteristics and outcomes of 193 patients with DLBCLs who were treated in the era before rituximab.
  • The 5-year overall survival (OS), progression-free survival (PFS), and disease-free survival (DFS) rates were 31%, 26%, and 47%, respectively, in patients with PTCLs and 59%, 55%, and 73%, respectively, in patients with DLBCL (P = .001, P < .001, and P = .003, respectively).
  • T-cell phenotype itself did not appear to have a significant impact on either response or survival.

  • [Title] CD52 expression in peripheral T-cell lymphomas determined by combined immunophenotyping using tumor cell specific T-cell receptor antibodies.
  • For peripheral T-cell lymphomas (PTCL), anti-CD52 (alemtuzumab) therapy is currently under investigation.
  • To accurately discriminate between the presumed mechanistically relevant CD52 expression in tumor versus bystander cells, we employed immunofluorescence double stains using CD52 in combination with an antibody directed against the rearranged T-cell receptor Vbeta-segment of the neoplastic clone in 6 angioimmunoblastic T-cell lymphomas (AITL) and 5 PTCL, unspecified (PTCL-NOS) and, in combination with CD30, in 18 anaplastic large cell lymphomas (ALCL).
  • Tumor cells in all AITL and PTCL-NOS were CD52 positive, while in 17 of 18 ALCL no specific staining was observed.
  • Conversely, the background T- and B-cell infiltrate showed a consistent positivity for CD52.
  • Our approach helps to precisely define CD52 expression in the tumor cell population of PTCL and might therefore be valuable when evaluating the response to alemtuzumab therapy in prospective clinical trials.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Nodal peripheral T-cell lymphomas correspond to distinct mature T-cell populations.
  • Peripheral T-cell lymphomas (PTCL) have not been successfully correlated with specific developmental stages of reactive T-cells.
  • In this study, we evaluated lymph node biopsies from eight PTCL-not otherwise specified (PTCL-NOS), seven angioimmunoblastic T-cell lymphomas (AILT), and 15 anaplastic large cell lymphomas (ALCL).
  • Detection of tumour cells with antibodies that recognize specific rearranged T-cell receptor Vbeta segments allowed us to investigate the expression of various differentiation-associated molecules.
  • All AILT and ALCL showed a homogeneous effector cell phenotype (CD45RA(-)/CD45R0(+)/CD27(-)), but differed in the cytotoxic and activation markers expressed.
  • Several (5/8) PTCL-NOS clustered together; these cases all exhibited a CD4(+) central memory cell phenotype (CD45RA(-)/CD45R0(+)/CD27(+)) and four expressed the lymph node homing receptor CCR7.
  • In conclusion, AILT and ALCL tumour cells correspond to different subsets of effector cells, while a subset of PTCL-NOS correlates with a non-effector T-cell population.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • AIMS: Protein kinase C (PKC) beta is an important regulator of lymphoid survival and its expression has been shown to be altered in lymphomas.
  • The aim was to determine the expression of PKC beta(2) in various subtypes of lymphoproliferative diseases by immunohistochemistry.
  • METHODS AND RESULTS: One hundred and forty archival samples representing various subtypes of lymphoproliferative diseases were analysed.
  • Certain subtypes, such as mantle cell, lymphocytic or follicular lymphoma, were found to express PKC beta(2) in > 90% of the samples.
  • In follicular lymphomas, the follicular lymphomatous areas were constantly labelled, whereas residual germinal centres remained negative.
  • Most angioimmunoblastic T-cell lymphomas, lymphoblastic T-cell lymphomas and marginal zone/mucosa-associated lymphoid tissue (MALT) lymphomas were labelled with anti-PKC betaII antibody, but the pattern of expression was more heterogeneous in these subtypes.
  • A minority of diffuse large B-cell lymphomas were stained and most plasma cell malignancies were negative.
  • None of the cases of Hodgkin's disease and anaplastic large cell lymphoma expressed PKC beta(2).
  • CONCLUSIONS: PKC beta(2) expression varies significantly among lymphoproliferative diseases.
  • In our series, the highest level of expression was found in mantle cell lymphomas and chronic lymphocytic lymphoma.

  • [Title] Usefulness of flow cytometry for differential diagnosis of precursor and peripheral T-cell and NK-cell lymphomas: analysis of 490 cases.
  • Although various CD markers have been analyzed in T-cell and natural killer (NK)-cell lymphomas, the sensitivity and specificity of these phenotypic features have not been satisfactorily characterized.
  • Flow cytometry (FCM) was used to determine the phenotypic pattern of 490 T/NK-cell lymphomas with the aid of a set of surface antigens (CD2, CD3, CD4, CD5, CD7, CD8, CD10, CD11c, CD16, CD19, CD20, CD25, CD30, CD34, and CD56).
  • In data obtained from 319 patients, CD10 expression was detected in 57% of angioimmunoblastic T-cell lymphomas, CD30 in 93% of anaplastic large cell lymphomas, CD34 in 50% of lymphoblastic lymphomas, and CD56 in 100% of extranodal NK/T-cell lymphomas nasal type.
  • A total of 92% of adult T-cell leukemia/lymphomas (ATLL) had expression of CD25 and downregulation of CD7.
  • Of special interest is that 92 ATLL (50%) were CD4+CD7-CD25+ phenotype while only four peripheral T-cell lymphoma unspecified (9%) and one (9%) cutaneous T-cell lymphoma had this phenotype.
  • Phenotypic analysis using FCM was thus found to be useful for differential diagnosis of T-cell and NK-cell lymphomas.

  • [Title] Follicular dendritic cell immunohistochemical markers in angioimmunoblastic T-cell lymphoma.
  • Angioimmunoblastic T-cell lymphoma is characterized by a paracortical proliferation of medium to large neoplastic T cells, often with clear cytoplasm, in a background of arborizing high endothelial venules, many surrounded by follicular dendritic cells (FDCs).
  • The authors stained a collection of 45 angioimmunoblastic T-cell lymphomas with CD21, CD23, CNA.42, cystatin A, and fascin for direct comparison of FDC staining characteristics in this setting.
  • CD21 highlighted the expected dendritic network of cell processes, within residual follicles and outside of follicles, often adjacent to proliferating vessels.
  • Cystatin A stained the cytoplasm of follicular dendritic cells within and outside of follicles; however, staining was often not sharply localized to dendritic cell processes, and scoring was further complicated by reactivity with other cell types in over half of the cases.
  • Likewise, fascin stained a variety of cell types, including strong staining of interdigitating dendritic-like cells, moderate staining of endothelial cells, and only weak staining of follicular dendritic cells within and outside of follicles.
  • Thus, CD21 remains the most reliable marker of follicular dendritic cells in angioimmunoblastic T-cell lymphoma.

  • Median time from diagnosis to Allo or Auto was 18 and 8mo, respectively.
  • The non-relapse mortality was 33%(Allo) and 8%(Auto).
  • For patients with resistant or relapsed disease, Allo should be strongly considered rather than Auto.

  • However, the superiority of high-dose chemotherapy followed by autologous stem cell transplantation (ASCT) has remained inconclusive.
  • We conducted a retrospective study of fifty six patients with three major nodal PTCL, histologically classified as PTCL-not specified (NOS, n=29), angioimmunoblastic T-cell lymphoma (AITL, n=19), and ALK-negative anaplastic large cell lymphoma (ALCL, n=8) who underwent ASCT (n=14) or not (n=42) after CT in Tokai University Hospital, Ebina General Hospital, and Hadano Red Cross Hospital, Kanagawa, Japan between 1997 and 2008.
  • METHODS: Retrospective, multicenter cohort study by time-dependent or non-time-dependent multivariate survival analysis with Cox proportional hazard regression.
  • In non-time-dependent analysis, both ASCT and sIL-R were significant prognostic factors for overall survival (OS).
  • On the other hand, ASCT was only important effect on progression-free survival (PFS) by non-time-dependent analysis, which HR was 0.20 (95%CI: 0.07-0.55, p=0.02).

  • [Title] Activity of lenalidomide in a phase II trial for T-cell lymphoma: Report on the first 24 cases.
  • : 8524 Background: Novel therapies are needed to improve outcomes in T-cell lymphomas.
  • We report the interim results of a prospective multicenter trial evaluating lenalidomide in T-cell lymphomas.
  • METHODS: Patients with relapsed and refractory T-cell lymphomas other than mycosis fungoides were prescribed oral lenalidomide (25mg daily) on days 1 to 21 of each 28 day cycle, with standardized dose reductions for toxicity.
  • Treatment continued until disease progression, death or unacceptable toxicity.
  • The histology was peripheral T-cell unspecified (PTCL-u, n=10), angioimmunoblastic (n=7), anaplastic large cell (n=5), enteropathic T-cell (n=1) and hepatosplenic gamma/delta (n=1).
  • Median number of prior therapies was 1 (range, 0-4), and three had prior autologous stem cell transplant.
  • Two patients had stable disease (SD) for ≥3 cycles.
  • Responses were seen in anaplastic, angioimmunoblastic, and PTCL-u histologies.
  • The most common grade 3 adverse events were neutropenia (20.8%), febrile neutropenia (16.7%), and pain NOS (16.7%).
  • CONCLUSIONS: In relapsed and refractory T-cell lymphomas, oral lenalidomide monotherapy has clinical activity and toxicity is consistent with the known profile of lenalidomide.
  • Further study of lenalidomide in these diseases is warranted.

  • [Title] [Histological and immunophenotypical characteristics of peripheral T-cell lymphomas].
  • Histopathologic features of immunohistochemically confirmed 37 nodal peripheral T-cell lymphomas are described.
  • Unspecified and 10 angioimmunoblastic T-cell lymphomas were analyzed.
  • The most demonstrative histological features of both types of lymphomas were spectrum of small, medium and large lymphoid cells, lymphoid cells with irregular nuclei, presence of clusters of clear cells, arborizing endothelial venules, increased number of histiocytes, eosinophils and plasma cells.
  • Delineation between peripheral T-cell lymphoma, unspecified and angioimmunoblastic T-cell lymphoma needs evaluation of follicular dendritic cell pattern.
  • The results suggest that detection of histopathologic features typical for peripheral T-cell lymphomas gives an opportunity to compose optimal panel for immunotyping which is absolutely necessary.

  • [Title] Autologous stem cell transplant in peripheral T cell lymphomas: Single institution 10-year retrospective analysis.
  • : e19538 Background: Peripheral T-cell lymphoma is a rare entitydisease, compromising 10% of non-Hodgkin's lymphoma worldwide and 5% of all lymphoid neoplasms in the United States.
  • High-dose chemotherapy followed by autologous haematopoietic stem cell transplantation, has been explored in recent years with little experiences.
  • METHODS: A retrospective analysis on patients with diagnosis of peripheral T-cell lymphoma receiving autologous stem cell transplant was conducted (January 1997 to July 2008).
  • The patients were stratified according to their International Prognostic Index (IPI), disease status at the time of transplant and histology type.
  • RESULTS: Twenty-nine subjects were identified, with a median age of 51; 13 patients had Anaplastic T cell, 18 patient had PTCL-nos, and 6 patients with angioimmunoblastic T cell lymphoma.
  • Seventeen patients (58.62%) presented with an aa IPI score greater than 2.4 patients were in complete remission, 15 at first relapse, 4 in greater than 1 episode, and 6 with refractory disease at the time of transplantion.Kaplan Meier overall survival (OS) 72 and relapse free survival (RFS) was 62 at 1 year respectively.
  • A multivariate analysis and new risk stratification based on the IPI score system and disease status at time of transplant were employed.
  • CONCLUSIONS: The status at time of transplant with new methods for evaluation of minimal residual disease may help in assessing outcome.

  • [Title] Epstein-Barr virus negative clonal plasma cell proliferations and lymphomas in peripheral T-cell lymphomas: a phenomenon with distinctive clinicopathologic features.
  • Clonal B-cell populations have been described in peripheral T-cell lymphomas (PTCL) as secondary Epstein-Barr virus (EBV) driven B-cell expansions that may evolve to an overt B-cell lymphoma.
  • EBV-negative B-cell proliferations associated with T-cell lymphomas are uncommon and not well characterized.
  • We studied 15 patients who developed an EBV-negative B-cell proliferation or malignant lymphoma associated with PTCL.
  • The T-cell tumors were 8 PTCL, not otherwise specified, 4 angioimmunoblastic T-cell lymphomas, and 3 cutaneous PTCL.
  • The B-cell component was intermingled with the PTCL in all patients and it was classified as clonal/monotypic plasma cell proliferation in 8 lesions, clonal/monotypic large B-cell proliferation in 4 patients, and B-cell lymphoma with plasmacytic/plasmablastic differentiation in 3 patients.
  • Two patients had 2 clonally unrelated plasma cell proliferations associated with the same PTCL.
  • Clonal IgH and T-cell receptor rearrangements were detected in 11/12 and 11/13 cases examined, respectively.
  • Sequential samples in 7 patients showed persistence of the PTCL and the B-cell component in 4, the PTCL without the B-cell lymphoma in 2, and progression of the B-cell neoplasm in 1.
  • In conclusion, EBV-negative clonal or mononotypic B-cell proliferations in patients with PTCL present with a spectrum of lesions ranging from plasma cell proliferations to overt lymphomas with plasmacytic/plasmablastic features.

  • [Title] Immunoreactivity of CD99 in non-Hodgkin's lymphoma: unexpected frequent expression in ALK-positive anaplastic large cell lymphoma.
  • To verify the spectrum of CD99-expressing lymphoid malignancy, an immunohistochemical study for CD99 was carried out in 182 cases of non-Hodgkin's lymphoma, including 21 lymphoblastic lymphomas, 11 small lymphocytic lymphomas, 9 mantle cell lymphomas, 12 follicular lymphomas, 37 diffuse large B cell lymphomas, 18 Burkitt's lymphomas, 28 NK/T-cell lymphomas, 8 angioimmunoblastic T-cell lymphomas, 23 peripheral T-cell lymphomas, unspecified, and 15 systemic anaplastic large cell lymphomas.
  • CD99 was positive in all T-lymphoblastic lymphomas and in 60% of B-lymphoblastic lymphomas.
  • Majority of T and NK cell lymphomas were negative for CD99, except anaplastic large cell lymphomas (ALCLs).
  • Of the mature B-cell lymphomas, 5.4% (2/37) of diffuse large B cell lymphomas and 11.1% (2/18) of Burkitt's lymphomas expressed CD99.
  • In conclusion, CD99 is infrequently expressed in mature B and T cell lymphomas, except ALK-positive ALCL.
  • High expression of CD99 in ALK-positive ALCL is unexpected finding and its biologic and clinical significances have yet to be clarified.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Class III beta-tubulin shows unique expression patterns in a variety of neoplastic and non-neoplastic lymphoproliferative disorders.
  • In Hodgkin lymphomas (HLs), 47.1% (40/85) expressed TUBB3 in the tumor cells with an all-or-none pattern.
  • TUBB3 expression in HL was more common in mixed cellularity type than nodular sclerosis type (P=0.032).
  • Among non-HLs, 79.3% (23/29) of anaplastic large cell lymphoma (ALCL), 8% (2/25) of extranodal natural killer/T-cell lymphoma, and 75% (21/28) of Burkitt lymphoma showed TUBB3 expression with an all-or-none pattern.
  • Of diffuse large B-cell lymphoma, 15.2% (32/210) expressed TUBB3 in a heterogeneous pattern.
  • Diffuse large B-cell lymphomas with a germinal center B-like subgroup exhibited TUBB3 expression more frequently than non-GCB-like subgroup (P=0.01).
  • Otherwise, none of the 18 angioimmunoblastic T-cell lymphomas; 18 peripheral T-cell lymphomas, not otherwise specified; 12 follicular lymphomas; 62 marginal zone lymphomas; 7 mantle cell lymphomas; 8 small lymphocytic lymphomas; or 2 FDC sarcomas expressed TUBB3.
  • In angioimmunoblastic T-cell lymphoma and Castleman disease, TUBB3 was positive in immunoblasts corresponding to Epstein-Barr virus-infected or Kaposi sarcoma herpes virus-infected cells.
  • A variety of neoplastic and non-neoplastic lymphoproliferative disorders exhibited characteristic TUBB3 expression patterns; these results suggest potential for diagnostic utility, some insight into the pathobiology of TUBB3 expression, and potential therapeutic implications.

  • [Title] High-dose therapy and autologous stem cell transplantation in Korean patients with aggressive T/NK-cell lymphoma.
  • The proportion of aggressive T/NK-cell lymphoma in Korea is larger than in the West, and it shows a lower response to conventional chemotherapy and poorer survival than diffuse large B-cell lymphoma.
  • This study was undertaken to evaluate the response rate and survival and to document the prognostic factors in patients with T/NK-cell lymphoma who have undergone high-dose therapy (HDT).
  • Eligibility for the study was a mature T/NK-cell lymphoma with initially poor risk (as high or high intermediate risk on age-adjusted International Prognostic Index) or relapsed cases.
  • Twelve patients had unspecified peripheral T-cell lymphomas, 7 anaplastic large-cell lymphomas, 6 nasal T/NK-cell lymphomas, and 3 angioimmunoblastic T-cell lymphomas.
  • Disease status at transplant were initially poor risk in 15, chemosensitive relapse in 8 and chemo-resistant relapse in 5 patients, respectively.
  • Absolute neutrophil count ( > 500/microl) recovered at a median 11 days after autologous stem cell transplantation in 26 patients.
  • Therefore, an initial approach with effective induction and HDT may result in a better outcome in T/NK-cell lymphoma.

  • OBJECTIVE: Membranous (M) cell of the human palatine tonsil is an antigen entry site for mucosal infection, but its location is obscure in histological sections.
  • Recently, a microarray analysis has demonstrated that clusterin, annexin A5, CD44, MMP14, and beta-tubulin are candidate genes of M cell marker in mice.
  • Among these genes, we here describe class II beta-tubulin as a new marker for human tonsillar M cells and follicular dendritic cells (FDCs), and present its usefulness for diagnosis of angioimmunoblastic T-cell lymphomas (AILTs).
  • MATERIALS AND METHODS: Immunohistochemistry and Western blotting for class II beta-tubulin were performed using 81 cases of lymphoid, gastrointestinal and thyroid tissues, and an FDC cell line, respectively.
  • Immunoblot analysis revealed that class II beta-tubulin expression was upregulated in HK cells, a normal FDC cell line.
  • Thus, class II beta-tubulin immunostaining may be useful to identify tonsillar M cells and to diagnose FDC proliferative lesions such as AILT.

  • [Title] Peripheral T-cell lymphoma with follicular T-cell markers.
  • INTRODUCTION: Peripheral T-cell lymphomas (PTCLs) in western countries are uncommon tumors with unfavorable prognosis.
  • They may be subclassified as anaplastic large-cell lymphomas (ALCLs), angioimmunoblastic-T-cell lymphomas (AITLs), or unspecified peripheral T-cell lymphomas (PTCLs-U).
  • The aim of this study was to establish whether other PTCL subgroups also express TFH cell markers.
  • PD-1-positive cases, which did not fulfill all the criteria for AITL, were further evaluated in whole-tissue sections for another 12 immunohistochemical markers, including the TFH cell markers CXCL13, CD10, and BCL6.
  • Clonal Ig and T-cell receptor rearrangements and Epstein-Barr virus-encoded RNA expression were also evaluated.
  • Morphologic, clinical, and follow-up data were reviewed.
  • RESULTS: Twenty-five out of 87 non-AITL cases (28.75%) showed PD-1 immunostaining.
  • All cases expressed at least 2 TFH cell markers.
  • Of the remainder, 1 was considered to be early AITL, 1 was diagnosed as ALCL-anaplastic lymphoma kinase-negative, and 4 of the other 6 PTCLs-U had morphology consistent with lymphoepithelioid (Lennert's) lymphoma.
  • CONCLUSIONS: TFH cell markers, especially PD-1, were expressed in a subset of PTCLs not classified as AITL, although most of them shared some morphologic features with AITL.
  • This suggests that the spectrum of AITL may be wider than previously thought, possibly including cases of lymphoepithelioid (Lennert's) lymphoma.

  • [Title] Angioimmunoblastic T cell lymphomas: frequent cutaneous skin lesions and absence of human herpes viruses.
  • BACKGROUND: Angioimmunoblastic T-cell lymphoma (AITL) is a complex lymphoproliferative disorder and often mimics a viral infection with frequent skin involvement.
  • In situ hybridization of EBV early region RNA (EBER) was performed and T cell receptor (TCR) gene rearrangement was also investigated in some cases.
  • CONCLUSION: Skin manifestation seems to be a cardinal component of AITL, be it in the context of presentation, progression or recurrent disease.

  • [Title] Frequent occurrence of B-cell lymphomas in angioimmunoblastic T-cell lymphoma and proliferation of Epstein-Barr virus-infected cells in early cases.
  • Secondary lymphomas occurring in the setting of angioimmunoblastic T-cell lymphoma (AILT) are considered to be rare.
  • A previous study detected a dysregulated hypermutation process in B-cells of AILT.
  • The present study aimed at estimating the frequency of B-cell lymphomas in AILT.
  • By studying the expression of EBV and activation-induced cytidine deaminase (AID) as an indicator of hypermutating cells, we assessed whether B-cell lymphoproliferations in AILT were strictly associated with EBV and whether hypermutation might contribute to lymphomagenesis.
  • Among 161 cases of AILT, diagnosed between 1996 and 2005 at the lymph node registry, Frankfurt, Germany, 19 cases were detected that also had B-cell non-Hodgkin lymphoma (NHL) and two cases had classical Hodgkin lymphoma (HL).
  • AID was expressed in AILT in large cells disseminated in the tissue, implying that the process of somatic hypermutation is ongoing in AILT, although the GC architecture is disrupted.
  • This might be relevant in the development of secondary lymphomas.

  • [Title] c-Maf expression in angioimmunoblastic T-cell lymphoma.
  • We previously examined c-Maf expression in various T-cell lymphomas by reverse-transcription polymerase chain reaction and found extremely elevated c-Maf levels in angioimmunoblastic T-cell lymphoma (AILT).
  • In this study, we examined T-cell lymphomas for c-Maf and cyclin expression immunohistochemically.
  • Of 93 cases of T-cell lymphomas we investigated in the current study, c-Maf expression was seen in 23 out of 31 cases of AILT, 3 out of 11 of adult T-cell leukemia/lymphoma, 4 out of 19 of peripheral T-cell lymphoma, unspecified [PTCL(U)], and 0 out of 11 cases of mycosis fungoides, 0 out of 11 of anaplastic large cell lymphoma, and 1 out of 10 of extranodal NK/T-cell lymphoma, nasal type.
  • Double immunostaining in AILT revealed that the majority of c-Maf-positive cells were also positive for CD43 (MT1), CD45RO (UCHL-1), and CD4 but were negative for CD20 (L26).
  • Additionally, cyclins D1 and D2, which stimulate cell cycle progression, were overexpressed in a large number of the c-Maf-positive AILT samples.
  • Quantitative reverse-transcription polymerase chain reaction analysis also showed that c-Maf was overexpressed in 8/31 cases of AILT, 0/19 cases of PTCL(U), 0/11 cases of anaplastic large cell lymphoma, 0/10 cases of extranodal NK/T-cell lymphoma, nasal type, and 2/8 cases of multiple myeloma, presenting significant difference between AILT and PTCL(U) (P=0.016, chi test).
  • These findings strongly suggest that CD4-positive neoplastic T cells in AILT show c-Maf expression and provide new insight into the pathogenesis of AILT suggesting c-Maf to be a useful diagnostic marker for AILT.

  • [Title] Multiple cutaneous monoclonal B-cell proliferations as harbingers of systemic angioimmunoblastic T-cell lymphoma.
  • We describe a 66-year-old man initially diagnosed with primary cutaneous marginal zone B-cell lymphoma who developed four additional monoclonal/monotypic B-cell lymphoid proliferations and a systemic angioimmunoblastic T-cell lymphoma over the course of 19 months.
  • Through retrospective analysis, we identified the evolution of a T-cell clone within the background of clinically and pathologically dominant cutaneous B-cell tumors.
  • In terms of clinical practice, this case supports that patients diagnosed with multiple clonal B-cell proliferation need thorough investigation and close clinical follow up to identify a coexistent or evolving systemic lymphoma, in particular, peripheral T-cell lymphomas of follicular T-helper cell type, such as angioimmunoblastic T-cell lymphoma.
  • Biologically, this case offers unique insight into the interactions between B-cell and T-cell lineages in lymphoid neoplasia.

  • [Title] Regulatory T-cell depletion in angioimmunoblastic T-cell lymphoma.
  • Angioimmunoblastic T-cell lymphoma (AITL) is the most frequent nodal T-cell lymphoma and is characterized by a polymorphic lymph node infiltrate, various dysimmune disorders, and a poor prognosis.
  • Regulatory T-cells (Treg) play an emerging role in the prognosis of non-Hodgkin B-cell lymphoma and mediate significant autoreactive T-cell suppression.
  • In this report, we demonstrate that numbers of Treg are significantly decreased in AITL lymph nodes [n = 30, 91 (40-195) per high power fields] compared with follicular lymphoma [n = 19, 179 (86-355)] and reactive lymph nodes [n = 8, 186 (140-265)].
  • Moreover, the few Treg in lymph nodes of AITL are resting Treg (rTreg) and have a naive CD45RA+, PD1-, and ICOS- phenotype [n = 5, 57% of Treg are CD45RA+ (16-96)], in contrast to the Treg in follicular lymphomas [n = 5, 7.4% (1-13)] or reactive lymph nodes [n = 7, 18.6% (6-48)].
  • Interestingly, Treg depletion was not observed in AITL peripheral blood at diagnosis.

  • [Title] Expression of CXCL13, a chemokine highly upregulated in germinal center T-helper cells, distinguishes angioimmunoblastic T-cell lymphoma from peripheral T-cell lymphoma, unspecified.
  • The germinal center T-helper cell has been proposed as the cell of origin for angioimmunoblastic T-cell lymphoma.
  • Our recent report of expression of CXCL13, a chemokine critical for germinal center formation and one of the most highly upregulated genes in the germinal center T-helper cell subset, in the majority of angioimmunoblastic T-cell lymphoma cases, provided further support for this theory.
  • To determine the specifity of this marker for angioimmunoblastic T-cell lymphoma, we evaluated CXCL13 expression in 26 nodal-based peripheral T-cell lymphomas and 14 lymph nodes showing paracortical lymphoid hyperplasia.
  • By WHO classification criteria, 20 of the lymphoma cases were considered peripheral T-cell lymphoma, unspecified, and six were reclassified as angioimmunoblastic T-cell lymphoma after immunohistochemical detection of disorganized follicular dendritic cell meshworks.
  • Combining the results of our studies, 31 of 35 angioimmunoblastic T-cell lymphoma cases (89%) showed CXCL13 expression, in contrast to two out of 20 peripheral T-cell lymphoma, unspecified cases (10%).
  • The two peripheral T-cell lymphoma, unspecified cases that were positive for CXCL13 showed a Lennert lymphoma-like histology.
  • While these cases did not meet all histologic criteria for angioimmunoblastic T-cell lymphoma, they did show an increase in EBV-positive B cells, suggesting they may be histologic variants of angioimmunoblastic T-cell lymphoma.
  • In conclusion, CXCL13 expression is a distinctive feature of angioimmunoblastic T-cell lymphoma, providing further support for the germinal center T-helper cell as the cell of origin for this neoplasm.
  • Given its specificity when compared to cases of peripheral T-cell lymphoma, unspecified as well as paracortical lymphoid hyperplasia, it may be a useful marker in the diagnosis of angioimmunoblastic T-cell lymphoma.

  • In most cases of lymphomas with blood dissemination, the careful cytological analysis of peripheral blood smears provides a rapid orientation to diagnosis, even if the final subtyping is achieved by histology and eventually other techniques.
  • Here, we evaluated if the analysis of blood smears may suggest the blood dissemination of angioimmunoblastic T-cell lymphoma (AITL) and if CD10 expression on neoplastic T cells, as recently reported on AITL, may contribute to the diagnosis.
  • In all, 11 lymph nodes and six peripheral blood samples from 12 patients with AITL were studied using four-colour flow cytometry associated to histological, cytological and molecular data.
  • Interestingly, all blood smears showed atypical lymphoid cells and a fraction of T cells expressed CD10 with a mean percentage of 18.75% (range 5.00-47.00%), regardless of lymphocytosis level and of rate of CD10 T cells in corresponding lymph node.
  • In contrast, in all control samples (100), none CD10-positive T cell was identified.
  • Therefore, they ought to be explored in further studies when aggressive lymphoma, in particular with lymphopenia and circulating atypical cells, is suspected.

  • [Title] Diffuse large B-cell lymphoma in patient after treatment of angioimmunoblastic T-cell lymphoma.
  • Relatively few cases of Epstein-Barr (EBV)-positive B-cell lymphomas arising in patients with angioimmunoblastic T-cell lymphoma (AITL) have been reported.
  • We report a case of AITL in which diffuse large B-cell lymphoma arose 13 months after the initial diagnosis of AITL.
  • In a 36-year-old female patient, evaluated for moderate leukocytosis, peripheral and abdominal lymphadenopathy AITL was diagnosed in March 2008, based on results of fine-needle aspiration cytology (FNAC) of the enlarged cervical and supraclavicular lymph nodes.
  • The diagnosis was also confirmed by immunophenotyping and histopathology of the cervical lymph nodes.
  • The patient initially recieved FED chemotherapy (fludarabine, cyclophosphamide, dexamethasone) followed by elective autologous hematopoietic stem cell transplantation.
  • In April 2009 the patient was hospitalized because of fever, pancytopenia, hyperbilirubinemia and peripheral lymphadenopathy.
  • CHOP-R chemotherapy (cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab) was then administered, resulting in good partial response of the disease.
  • Reduced intensity allogeneic stem cell transplantation performed thereafter, resulted in complete remission of the disease.
  • AITL is a rare lymphoproliferative disorder in which the neoplastic T-cells represent the minority of the lymph node cell population and almost all cases harbor EBV-infected B-cells.
  • Various authors postulated that immunodeficiency in AITL patients together with immunosuppressive effects of cytotoxic drugs, may be responsible for EBV-induced proliferation of latently or newly EBV-infected B-cells with eventual clonal selection and progression to aggressive B-cell lymphoma.

  • Reports focusing on the immunological microenvironment of peripheral T-cell lymphomas (PTCL) are rare.
  • Here we studied the reciprocal contribution of regulatory (Treg) and interleukin-17-producing (Th17) T-cells to the composition of the lymphoma-associated microenvironment of angioimmunoblastic T-cell lymphoma (AITL) and PTCL not otherwise specified on tissue microarrays from 30 PTCLs not otherwise specified and 37 AITLs.
  • We found that Th17 but not Treg cells were differently represented in the two lymphomas and correlated with the amount of mast cells (MCs) and granulocytes, which preferentially occurred in the cellular milieu of AITL cases.

  • [Title] Angiogenic mediators of the angiopoietin system are highly expressed by CD10-positive lymphoma cells in angioimmunoblastic T-cell lymphoma.
  • Angioimmunoblastic T-cell lymphoma (AILT) is a malignant disease of peripheral T-cell origin that is characterized by a prominent proliferation of high endothelial venules in the lymph node.
  • To investigate angiogenic mechanisms in AILT we measured the angiogenic mediator gene expression levels in the lymph nodes of 54 non-Hodgkin lymphoma patients, by immunostaining and quantitative reverse transcription polymerase chain reaction.
  • Angiogenic mediators angiopoietin (Ang) 1 (ANGPT1), Ang2 (ANGPT2) and their receptor, Tie2 (TEK), vascular endothelial growth factor (VEGF; VEGFA) and its receptor, VEGFR2 (KDR), and hepatocyte growth factor (HGF) and its receptor, c-Met (MET) were all more highly expressed in AILT lymph nodes (16 cases) than in B-cell lymphomas (24 cases).
  • Moreover, significantly higher Ang1 and Tie2 expression was detected in AILT cases with CD10-positive neoplastic T-cells by comparison with unspecified peripheral T-cell lymphoma (14 cases).
  • These results suggest that the angiopoietin system may play an important role in the development of high vascularity in AILT lymph nodes.
  • Consequently, as neoplastic T-cells and follicular dendritic cells are both increased in AILT and may represent an important source of angiogenic mediators, targeting these cells with anti-angiogenic strategies might represent a novel therapy for AILT.

  • However, few cases of Epstein-Barr virus-positive B-cell lymphoma arising in patients with preexisting angioimmunoblastic T-cell lymphoma have been reported.
  • We report a case of angioimmunoblastic T-cell lymphoma in which diffuse large B-cell lymphoma developed 56 months after the diagnosis of angioimmunoblastic T-cell lymphoma.
  • The patient survived for 9 years after the initial diagnosis of angioimmunoblastic T-cell lymphoma, and molecular studies performed on multiple biopsy specimens during this period revealed the dynamic nature of clonal lymphoid expansion.
  • Epstein-Barr virus latent membrane protein 1 and Epstein-Barr virus-encoded RNA were detected in the diffuse large B-cell lymphoma, suggesting that Epstein-Barr virus may have played a role in the pathogenesis of the diffuse large B-cell lymphoma.

  • [Title] Eosinophilic pleural effusion as the first presentation of angioimmunoblastic T cell lymphoma.
  • Eosinophilic pleural effusion (EPE), defined as pleural effusion that contains at least 10% eosinophils among the leukocytes, can be a manifestation of a great variety of diseases.
  • However, eosinophilia is a relatively rare finding in malignant pleural effusions, and it has been used as an indicator of good prognosis.
  • In clinical experience, very few cases of malignant lymphomas accompanied by EPE have been reported.
  • Pleural biopsy could not yield a definite diagnosis initially.
  • Six months later, bilateral neck, axillary and inguinal lymphadenopathy developed, and lymph node biopsy confirmed the diagnosis of angioimmunoblastic T cell lymphoma, with positive CD10 expression.
  • Therefore, we retrospectively carried out CD10 staining of the sample obtained from pleural biopsy and the positive result confirmed that the etiology of EPE was due to malignant T cell lymphoma.

  • [Title] [Morphologic and immunophenotypic analysis of angioimmunoblastic T-cell lymphoma].
  • OBJECTIVE: To study the morphologic and immunophenotypic features of angioimmunoblastic T-cell lymphoma (AITL), as well as the origin of the proliferative follicular dendritic cells (FDCs) in AITL.
  • Cases of peripheral T-cell lymphoma, unspecified, extranodal NK/T-cell lymphoma, nasal-type, enteropathy-type T-cell lymphoma, anaplastic large cell lymphoma, subcutaneous panniculitis-like T-cell lymphoma and reactive lymphoid proliferation were selected as controls.
  • RESULTS: Amongst the 29 cases of AITL studied, 75.9% (22/29) showed aberrant expression of CD10, while all except one of the controlled cases were negative, 82.8% (24/29) of the AITL cases expressed CXCL13, while all cases of peripheral T-cell lymphoma, unspecified were negative.

  • [Title] The frequency of B- and T-cell gene rearrangements and epstein-barr virus in T-cell lymphomas: a comparison between angioimmunoblastic T-cell lymphoma and peripheral T-cell lymphoma, unspecified with and without associated B-cell proliferations.
  • 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.

  • Pure red cell aplasia is a bone marrow failure characterized by a progressive normocytic anemia and reticulocytopenia without leucopenia and thrombocytopenia.
  • It is associated with various hematologic diseases.
  • However, pure red cell aplasia with angioimmunoblastic T cell lymphoma has rarely been reported.
  • Here we describe a 43-year-old woman with pure red cell aplasia associated with angioimmunoblastic T-cell lymphoma.
  • A CT scan of the abdomen revealed marked hepatosplenomegaly and small multiple lymphadenopathies.
  • A bone marrow biopsy revealed focal infiltration of abnormal lymphoid cells and absence of red cell precursors.
  • Splenic biopsy was compatible with angioimmunoblastic T-cell lymphoma.
  • Ultimately, diagnosis of pure red cell aplasia associated with angioimmunoblastic T-cell lymphoma was made.

  • The human lymph node is a complex tissue resulting from the microenvironmental organisation of different cell populations linked by topographical and/or functional relationships.
  • On the whole, GC exerts a role in B cell physiology and malignancy.
  • In GC-derived lymphomas, gene expression profiling studies have raised the possibility that survival of the affected patients may be associated with signatures preferentially expressed in non-malignant T cells and macrophages and/or dendritic cells.
  • Immunohistological analyses in lymphoma biopsy samples have confirmed that the biological behaviour and tumour progression may be influenced by the tumour microenvironment.
  • This review will examine GC-derived lymphomas, including follicular lymphomas, Hodgkin lymphomas and angioimmunoblastic T-cell lymphoma, through their integrated cellular microenvironment, highlighting those findings which may serve as a useful surrogate marker for tumour diagnosis or tumour progression, together with key molecules involved in tumour development.

  • BACKGROUND: Cardiac tamponade (CT) as the primary clinical manifestation of lymphomas is extremely rare.
  • Angioimmunoblastic T-cell lymphoma (AILT) is characterised by systemic disease usually presenting with generalised peripheral lymphadenopathy, hepatosplenomegaly, and bone marrow infiltration.
  • CASE REPORT: We report on a 59-year-old male patient with CT as initial clinical manifestation of AILT.
  • Coexistence with malignant pleural mesothelioma was additionally revealed.
  • Cytologic examination of pericardial fluid presented diffuse lymphoid cells and sporadic malignant mesothelial cells.
  • AILT diagnosis was confirmed by thoracoscopic mediastinal lymph node and bone marrow biopsy.
  • Despite the presence of pleural effusion, the diagnosis of mesothelioma was initially established by cytologic ex-amination of pericardial fluid, due to the patient's critical cardiac condition requiring prompt subxiphoid pericardiocentesis.
  • CONCLUSION: CT as primary clinical manifestation of AILT is very rare.
  • This case reflects the differences in the underlying biology of AILT and consequently the vast spectrum of its clinical presentations.

  • [Title] Spectrum of bone marrow findings in patients with angioimmunoblastic T-cell lymphoma.
  • Bone marrow (BM) biopsy is often performed early in the evaluation of patients with angioimmunoblastic T-cell lymphoma (AITL), and may be the first diagnostic tissue sample; yet the BM histopathology associated with this disease has not been well described.
  • Seven (54%) were involved by AITL, which was characterised by paratrabecular and interstitial polymorphous infiltrates containing cytologically atypical lymphocytes, histiocytes and eosinophils.
  • As in lymph nodes, the lymphomatous infiltrate in some BMs contained numerous small or scattered large B cells, resembling either benign lymphoid aggregates or T cell rich large B cell lymphoma, respectively.
  • When BM biopsy preceded the diagnosis of AITL, these secondary changes were misinterpreted as chronic myeloproliferative disease (n = 2), or plasma cell dyscrasia (n = 2).
  • The spectrum of BM findings in AITL patients is important to recognise for early and accurate diagnosis in this disease.

  • [Title] Morphologic and immunophenotypic analysis of angioimmunoblastic T-cell lymphoma: Emphasis on phenotypic aberrancies for early diagnosis.
  • The morphologic features and immunophenotype of diagnostic nodal and bone marrow biopsy specimens were reviewed in 29 well-established cases of angioimmunoblastic T-cell lymphoma (AILT).
  • All cases showed a characteristic polymorphous lymphoid and inflammatory cell infiltrate along with stromal-vascular changes.
  • Unique architectural changes, including extranodal extension (83%), follicular dendritic cell proliferation (93%), and a distinctly marginalized distribution of residual B cells (67%) were observed.
  • Subsets of T cells with immunophenotypic abnormalities (CD10 coexpression or loss of pan-T-cell antigens CD3 and CD7) were identified in a majority of cases (96%).
  • Significantly, these morphologic and phenotypic features were seen irrespective of the presence of an overt lymphomatous pattern.
  • Our results indicate that unique morphologic alterations and subsets of phenotypically aberrant T cells are present consistently in nearly all cases of AILT, including morphologically less definitive biopsy specimens.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] [Analysis of overexpression of vascular endothelial growth factor-C in patients with angioimmunoblastic T-cell lymphoma].
  • OBJECTIVE: To explore the vascular endothelial growth factor-C (VEGF-C) expression and its clinical significance in malignant lymphoma.
  • METHODS: Lymphoma cells were isolated by laser microdissection.
  • VEGF-C expression in lymphoma tissue and microdissected lymphoma cells was measured by realtime quantitative PCR.
  • RESULTS: Comparing with that in 8 patients with reactive lymphocyte hyperplasia, VEGF-C was overexpressed in angioimmunoblastic T-cell lymphoma, both in lymphoma tissue (n = 18, P = 0.0020) and in microdissected lymphoma cells (n = 10, P < 0.0001).
  • CONCLUSION: The value of VEGF-C expression might be a biomarker of disease progression in angioimmunoblastic T-cell lymphoma.

  • Peripheral T-cell lymphoma (PTCL) is often challenging to diagnose and classify.
  • Gene expression profiling was performed on 144 cases of PTCL and natural killer cell lymphoma and robust molecular classifiers were constructed for angioimmunoblastic T-cell lymphoma (AITL), anaplastic lymphoma kinase-positive (ALK(+)) anaplastic large-cell lymphoma (ALCL), and adult T-cell leukemia/lymphoma.
  • Many of the pathologic features and substantial components of the molecular signature of AITL are contributed by the follicular dendritic cells, B-cell, and other stromal components.
  • The expression of Th17-associated molecules in ALK(+) ALCL was noted and may represent aberrant activation of Th17-cell differentiation by abnormal cytokine secretion.
  • Adult T-cell leukemia/lymphoma has a homogeneous molecular signature demonstrating high expression of human T-lymphotropic virus type 1-induced genes.

  • BACKGROUND/AIMS: Epstein-Barr virus (EBV) is involved in the pathogenesis of angioimmunoblastic T-cell lymphoma (AILT), but its precise role and prognostic impact are not clear.
  • This study aimed to evaluate the incidence of EBV-postitivity in the tumor and bone marrow (BM) samples from AILT patients, and their correlations with the clinical variables and patient survival.
  • METHODS: Seventy AILT cases were identified over a period of 8 years.
  • In 13 (48%) patients, gross tumor involvement was recognized by hematoxylin-eosin staining at the time of diagnosis.
  • CONCLUSIONS: EBV-positivity of tumor had no impact on the prognosis of AILT patients.

  • [Title] Angioimmunoblastic T-cell lymphoma in bone marrow: a morphologic and immunophenotypic study.
  • Angioimmunoblastic T-cell lymphoma is known to frequently involve bone marrow.
  • However, the histologic and immunophenotypic features of angioimmunoblastic T-cell lymphoma at this site are poorly defined.
  • We assessed 27 bone marrow specimens involved by angioimmunoblastic T-cell lymphoma from 20 patients.
  • Flow cytometry immunophenotyping revealed a CD3+CD10+ T-cell population in 2 (25%) of 8 cases assessed.
  • We conclude that the recognition and classification of angioimmunoblastic T-cell lymphoma in bone marrow are made difficult by the uncommon expression of CD10 (25%), rarity of follicular dendritic cells, and lack of CXCL13 expression at this site.
  • By contrast, programed death-1 immunohistochemical staining and double labeling using antibodies specific for BCL-6 and CD3 were helpful in appreciating the follicular T-helper cell immunophenotype of angioimmunoblastic T-cell lymphoma.

  • [Title] Histologic evolution of angioimmunoblastic T-cell lymphoma in consecutive biopsies: clinical correlation and insights into natural history and disease progression.
  • Angioimmunoblastic T-cell lymphoma (AITL) is an uncommon, but aggressive nodal peripheral T-cell lymphoma.
  • Eleven cases where polymerase chain reaction results for T-cell receptor-gamma gene rearrangement were directly compared showed an identical band-size in the initial and follow-up biopsies.
  • Seven cases (23%) developed EBV-associated B-cell lymphomas [5 diffuse large B-cell lymphoma (DLBCL) and 2 classic Hodgkin lymphoma].
  • In 4 cases, a dominant B-cell clone was observed in biopsies lacking evidence of DLBCL.
  • A single case was complicated by EBV-negative DLBCL, whereas another with large cell transformation had a T-cell phenotype.
  • In conclusion, AITL represents a clonal T-cell proliferation with a stable T-cell clone throughout the disease.
  • When "morphologic high-grade transformation" occurs, it is usually due to a secondary (often EBV-associated) B-cell lymphoma, rather than a T-cell neoplasm.

  • [Title] Chromosomal aberrations in angioimmunoblastic T-cell lymphoma and peripheral T-cell lymphoma unspecified: A matrix-based CGH approach.
  • Angioimmunoblastic T-cell lymphoma (AILT) is a histopathologically well-defined entity.
  • However, despite a number of cytogenetic studies, the genetic basis of this lymphoma entity is not clear.
  • Moreover, there is an overlap to some cases of peripheral T-cell lymphoma unspecified (PTCL-u) in respect to morphological and genetic features.
  • We used array-based comparative genomic hybridization (CGH) to study genetic imbalances in 39 AILT and 20 PTCL-u.
  • Array-based CGH revealed complex genetic imbalances in both AILT and PTCL-u.
  • Chromosomal imbalances were more frequent in PTCL-u than in AILT and gains exceeded the losses.
  • The most recurrent changes in AILT were gains of 22q, 19, and 11p11-q14 (11q13) and losses of 13q.
  • Interestingly, gains of 4q (4q28-q31 and 4q34-qtel), 8q24, and 17 were significantly more frequent in PTCL-u than in AILT.
  • Moreover, we could identify a recurrent gain of 11q13 in both AILT and PTCL-u, which has previously not been described in AILT.
  • Trisomies 3 and 5, which have been described as typical aberrations in AILT, were identified only in a small number of cases.
  • In conclusion, CGH revealed common genetic events in peripheral T-cell lymphomas as well as peculiar differences between AILT and PTCL-u.

  • To evaluate the clinical, pathological characters and prognosis of patients with angioimmunoblastic T cell lymphoma (AITL), the clinicopathologic features, immunophenotypes, therapy and survival rate of 12 AITL patients which were confirmed by pathologic examination were retrospectively studied.
  • The results indicated that main symptom was observed as general lymphadenopathy, however, 9 patients had fever.
  • The diagnosis of AITL was based on lymph-node biopsy.
  • The histopathologic characteristics of AITL showed the damage of normal lymphnode structure, the proliferation of immunoblastic cells and arborescent super vascularization.
  • All immunophenotypes were mature peripheral T-cellular.
  • In conclusion, most cases of AITL display an aggressive course, therefore, the disease progresses rapidly and has unfavorable prognosis, further studies are required to improve its therapy regimen.

  • [Title] The inducible T-cell co-stimulator molecule is expressed on subsets of T cells and is a new marker of lymphomas of T follicular helper cell-derivation.
  • BACKGROUND: T follicular helper (T(FH)) cells reside in the light zone of germinal centers and are considered the cell of origin of angioimmunoblastic T-cell lymphoma.
  • Recently, CXCL13, PD-1 and SAP were described as useful markers for T(FH) cells and angioimmunoblastic T-cell lymphoma but also reported in some peripheral T-cell lymphomas, not otherwise specified.
  • DESIGN AND METHODS: In the present study the expression pattern of ICOS protein was investigated by immunohistochemistry-based techniques in routine sections of normal lymphoid tissues and 633 human lymphomas.
  • In lymphomas, ICOS expression was confined to angioimmunoblastic T-cell lymphoma (85/86), peripheral T-cell lymphomas of follicular variant (18/18) and a proportion of peripheral T-cell lymphomas, not otherwise specified (24/56) that also expressed other T(FH)-associated molecules.
  • CONCLUSIONS: ICOS is a useful molecule for identifying T(FH) cells and its restricted expression to angioimmunoblastic T-cell lymphoma and a proportion of peripheral T-cell lymphomas, not otherwise specified (showing a T(FH)-like profile) suggests its inclusion in the antibody panel for diagnosing T(FH)-derived lymphomas.
  • Our findings provide further evidence that the histological spectrum of T(FH)-derived lymphomas is broader than previously assumed.

  • Recent studies have drawn attention to the biological overlap between classical Hodgkin lymphoma (CHL) and diffuse large B-cell lymphomas (DLBCL).
  • Similarly, there is a greater appreciation of the borderlands between Burkitt lymphoma and DLBCL.
  • Among the peripheral T-cell lymphomas (PTCL), more precise definitions were introduced for several entities, including anaplastic large cell lymphoma, angioimmunoblastic T-cell lymphoma, enteropathy-associated T-cell lymphoma, and subcutaneous panniculitis-like T-cell lymphoma.
  • Several new variants of primary cutaneous T-cell lymphomas are proposed.
  • Finally, the subclassification and categorization of the most common lymphoma subtypes, follicular lymphoma (FL) and DLBCL, were altered to enhance diagnostic accuracy and aid in clinical management.

  • To evaluate the prognostic significance of clinicobiologic and pathological features in angioimmunoblastic T-cell lymphoma (AITL), 157 AITL patients were retrieved from the GELA LNH87-LNH93 randomized clinical trials.
  • In multivariate analysis, only male sex (P = .004), mediastinal lymphadenopathy (P = .041), and anemia (P = .042) adversely affected overall survival.
  • In conclusion, AITL is a morphologically heterogeneous T-cell lymphoma commonly expressing CXCL13 and CD10 and carrying few prognostic factors.

  • We report a case of a 66-year-old Japanese woman who developed diffuse large B-cell lymphoma (DLBCL) in her small intestine after chemotherapy for AITL.
  • In situ hybridization for EBV-encoded RNA revealed positivity in the lymphoma cells.
  • The lymph nodes diagnosed as AITL were negative for EBV infection and there was no coexistence of B cell neoplasms in them.
  • We thought small bowel perforation in this case was caused by EBV-associated B cell lymphoma secondary to AITL.
  • Our case showed a remarkable deficiency of cellular immunity after chemotherapy, which we postulate was related to the cause of occurrence of B-cell lymphoma.

  • OBJECTIVE: To study the value of immunomarkers CXCL13, CD10, bcl-6 in pathologic diagnosis of angioimmunoblastic T-cell lymphoma (AITL).
  • METHODS: One hundred and fifteen cases of AITL, 30 cases of peripheral T-cell lymphoma, not otherwise specified (PTCL, NOS) and 30 cases of reactive lymph nodes with paracortical hyperplasia (RH) encountered during the period from January, 1990 to January, 2008 were retrieved from the archival files of the Department of Pathology, West China Hospital of Sichuan University, China.
  • The morphologic features were reviewed and compared.
  • RESULTS: Regressed follicles were evident in 7.8% (9/115) of AITL cases, 6.7% (2/30) of PTCL, NOS cases and 83.3% (25/30) of RH cases, respectively.
  • A marked increase of number of arborizing venules was shown in 98.3% (113/115) of AITL cases, 63.3% (19/30) of PTCL, NOS cases and 76.7% (23/30) of RH cases, respectively.
  • In AITL, 96.5% (111/115) of cases showed CXCL13 expression, in contrast to 26.7% (8/30) of PTCL, NOS.
  • Expression of CD10 and bcl-6 were found in the neoplastic cells in 50.4% (58/115) and 78.3% (90/115) of AITL, and 3.3% (1/30) and 3.3% (1/30) of PTCL, NOS, respectively.
  • CONCLUSIONS: AITL is a type of lymphoma originated from the follicular helper T cells.
  • Detailed morphologic assessment and use of immunohistochemical markers are essential for accurate diagnosis.

  • All of the patients received CHOP-like regimens as initial chemotherapy, including 4 once treated with radiotherapy and 1 with high dose therapy followed by autologous stem cell transplantation (HDT-ASCT) as upfront consolidation therapy.
  • B-cell, T-cell and NK-cell subgroup proportions in the peripheral blood were tested by flow cytometry in 6 patients.
  • With the median follow-up of 26 months, the overall 2-year survival and disease free survival (DFS) rates were 62.2% and 44.4%, respectively.
  • In the univariate analysis, only age > 30 years and primary refractory disease adversely affected overall survival (OS); age > 30 years, advanced stage, B symptoms and splenomegaly adversely affected DFS.
  • Flow cytometry of peripheral blood lymphocytes showed that 5 of the 6 tested cases had decreasing proportion of CD3(+)CD4(+) T cells, B cells and NK cells but elevated CD3(+)CD8(+) T cells.
  • Two heavily treated patients achieved partial and complete response by thalidomide therapy, with a progression free survival (PFS) of 2 and 6+ months, respectively.

  • [Title] The clonality of CD3+ CD10+ T cells in angioimmunoblastic T cell lymphoma, B cell lymphoma, and reactive lymphoid hyperplasia.
  • T cells coexpressing CD3 and CD10 are a characteristic feature of angioimmunoblastic T-cell lymphoma (AITL) [1].
  • However, they are not unique to AITL, as these cells are also present in B cell lymphoma and reactive lymphoid hyperplasia [2].
  • To determine the significance of CD3+ CD10+ T cells, we used flow cytometry with cell sorting and molecular biology techniques for T cell gene rearrangement to study T cells from patients with AITL, B cell lymphoma, and reactive lymph node hyperplasia.
  • We found that CD3+ CD10+ T cells in B cell lymphoma and reactive lymphoid hyperplasia were polyclonal.
  • These findings illustrate the differences between early and late lymphoma and could be important for the diagnosis of AITL.

  • [Title] Morphologic and immunophenotypic variants of nodal T-cell lymphomas and T-cell lymphoma mimics.
  • Given their relative rarity, one of the primary diagnostic difficulties in nodal T-cell lymphomas is recognizing their range of histologic patterns.
  • This is complicated by the fact that most mature T-cell lymphomas retain some functional characteristics of nonneoplastic T cells, ie, the capacity to secrete cytokines and costimulate immune cell growth, and, thus, are associated with obscuring nonneoplastic immune cells.
  • Sessions 2 and 3 of the Society for Hematopathology/European Association for Haematopathology Workshop focused on these issues and conditions that may simulate T-cell lymphomas.
  • We summarize salient features of presented cases, including the varied patterns seen in angioimmunoblastic T-cell lymphoma (AITL) and other more poorly characterized morphologic and functional nodal T-cell lymphoma subsets.
  • Many cases illustrated the difficulties distinguishing AITL from peripheral T-cell lymphoma, unspecified, when the neoplasms manifest only some AITL features.
  • The usefulness of separately classifying T-cell lymphomas that demonstrate follicular, perifollicular, or T-zone patterns of infiltration; significance of immunophenotypically distinct subsets that express cytotoxic markers or have features of central memory T cells; diagnostic difficulties posed by B-cell proliferations that accompany T-cell lymphomas; and T-cell lymphoma mimics related to genetic disorders, immune dysregulation, and drug reactions are also discussed.

  • [Title] Angioimmunoblastic T-cell lymphoma: a relatively common type of T-cell lymphoma in Sjögren's syndrome.
  • An increased risk of developing lymphoma has been indicated in Sjögren's syndrome (SS), and the lymphomas in SS are usually B-cell type in origin.
  • Interestingly, despite the rather low frequency of T-cell lymphoma in SS, angioimmunoblastic T-cell lymphoma (AILD) constitute the majority of T-cell lymphomas associated with SS.
  • To the best of our knowledge, including our case, at least 11 out of 23 (48%) cases of T-cell lymphoma reported in association with SS, were AILD.
  • The fact that the development of B-cell lymphoma in SS is much more frequent than that of T-cell lymphoma, might be explained by differences in the situation between B and T cells, although the exact mechanism still remains uncertain.

  • [Title] [Angioimmunoblastic T-cell lymphoma complicated by recurrent drug-induced agranulocytosis].
  • A 73-year-old man was hospitalized with fever, erythema, generalized superficial lymphadenopathy and marked neutropenia in July 2007.
  • Hematologic examination demonstrated a white blood cell count of 1,400/microl with 0% neutrophils, and 18% abnormal lymphocytes.
  • A diagnosis of drug-induced agranulocytosis was made.
  • Although neutrophil counts immediately returned to normal levels in response to filgrastim, fever, skin rash and systemic lymphadenopathy were all persistent.
  • Based on the histologic findings, PCR, and immunohistologic analyses, he was diagnosed with angioimmunoblastic T cell lymphoma (AILT) in leukemic state.

  • [Title] Expression of two markers of germinal center T cells (SAP and PD-1) in angioimmunoblastic T-cell lymphoma.
  • BACKGROUND AND OBJECTIVES: In the present paper we report that SAP, an intracytoplasmic molecule that is involved in cell signaling, is an immunohistologic marker for germinal center T cells in paraffin-embedded tissue.
  • We document its expression, and also that of PD-1 (another recently described marker of germinal center T cells to which a new antibody has been raised), in normal and neoplastic lymphoid tissue to evaluate the suggestion that helper T cells within the germinal centers of human lymphoid tissue are the cell of origin of angioimmunoblastic T-cell lymphoma (AITL), and to assess the diagnostic value of these two markers.
  • DESIGN AND METHODS: Expression of SAP and PD-1 was investigated by immunohistochemistry in paraffin-embedded tissue sections and in cell lines.
  • Western blotting was performed on cell lines, and antibody specificity was confirmed by immunostaining of transfected cells.
  • RESULTS Screening on more than 500 lymphoma biopsies showed that 95% (40/42) of cases of AITL expressed at least one of these markers.
  • However, PD-1 and SAP were also found in a minority of cases of peripheral T-cell lymphoma other than AITL, in contrast to a report that the former marker is specific for AITL.
  • This observation raises the possibility that such non-angioimmunoblastic cases may be related to germinal center helper T cells.
  • They may also prove of value in the diagnosis of this disease since a negative reaction was rarely observed in this disorder.

  • [Title] Expression of CXCL13 by neoplastic cells in angioimmunoblastic T-cell lymphoma (AITL): a new diagnostic marker providing evidence that AITL derives from follicular helper T cells.
  • Angioimmunoblastic T-cell lymphoma (AITL) represents a distinct entity among peripheral T-cell lymphomas (PTCLs).
  • It has been recently shown that expression of CXCL13, a chemokine critically involved in B-cell migration into germinal centers, is characteristic of TFH cells, as compared with other T helper subsets.
  • We compared CXCL13 expression in 29 AITLs, 20 PTCLs, unspecified, 10 anaplastic large cell lymphomas (ALCL), and 4 other PTCLs.
  • We conclude that CXCL13 expression is a common characteristic of AITL, which can help to delineate the morphologic spectrum of the disease, and further supports its derivation from TFH cells.
  • CXCL13 expression may also provide an additional useful tool for the diagnosis of AITL.

  • [Title] Programmed death 1 is a marker of angioimmunoblastic T-cell lymphoma and B-cell small lymphocytic lymphoma/chronic lymphocytic leukemia.
  • PD-1 expression was recently reported in some T-cell non-Hodgkin lymphoma (NHL) subtypes, but the expression profile of PD-1 and its ligands (PD-L1 and PD-L2) in B-NHLs remains largely to be characterized.
  • A series of 161 lymphoma tissue and 11 blood samples was analyzed using either immunohistochemistry or flow cytometry.
  • In B-NHLs, PD-1 was mainly expressed in reactive T cells; but expression was also noted in neoplastic B cells from small lymphocytic lymphoma (SLL, 12/13), grade III follicular lymphoma (3/3), and diffuse large cell lymphoma (2/25).
  • In contrast, neoplastic B cells from mantle cell lymphoma (0/11), marginal zone lymphoma (0/12), Burkitt lymphoma (0/3), and grade 1 to 2 follicular lymphoma (0/40) were PD-1 negative.
  • PD-L1 and PD-L2 were negative in small B-cell lymphomas, including B-SLL.
  • PD-1 expression in T-NHLs was restricted to the angioimmunoblastic subtype (8/8).
  • Because the anti-PD-1.6.4 antibody works on paraffin sections, it represents a useful tool to differentiate SLL/CLL from other small B-cell lymphomas.

  • [Title] Advances in the understanding and management of angioimmunoblastic T-cell lymphoma.
  • Angioimmunoblastic T-cell lymphoma (AITL) is a distinct peripheral T-cell lymphoma (PTCL) entity with peculiar clinical and pathological features.
  • The recent identification of follicular helper T (T(FH)) cell as the cell of origin of this neoplasm represents a major step in our understanding of the pathobiological characteristics of the disease and should, in the future, clarify the diagnostic criteria for AITL and help to delineate its spectrum, especially from PTCL, not otherwise specified (PTCL, NOS).
  • Deciphering the pathogenesis of the disease is needed to identify targets for new therapies that are expected to improve the poor outcome of AITL patients, when treated with conventional chemotherapy regimens.

  • We report an unusual case of angioimmunoblastic T cell lymphoma arising in the setting of 5 years of immunosuppressive treatment for progressive systemic sclerosis.
  • Southern blot study demonstrated the clonal rearrangement of T cell receptor beta-chain gene, but not of immunoglobulin heavy chain gene.
  • Phenotypical examination of the lymph node also revealed the predominance of CD4+ T cells in addition to the proliferation of follicular dendritic cells, but no light chain restriction in large B cell components.
  • Based on the combined data described here, our preferred diagnosis was angioimmunoblastic T cell lymphoma with Epstein-Barr virus-associated B cell lymphoproliferative disorder, the pathogenesis of which was suggested to be closely associated with immunosuppressive treatment for progressive systemic sclerosis.

  • [Title] Monoclonality and oligoclonality of T cell receptor beta gene in angioimmunoblastic T cell lymphoma.
  • Angioimmunoblastic T cell lymphoma (AILT) is an aggressive T cell lymphoma with an incidence of approximately 1-2% of all non-Hodgkin lymphoma.
  • The detection of clonal T cell receptor (TCR) gene rearrangements helps in the diagnosis of T cell malignancies such as AILT, where morphological and immunohistological investigations are not always sufficient to reach a definitive diagnosis.
  • TCR beta (TCRB) and TCR gamma (TCRG) gene rearrangements were analysed from 17 WHO-defined cases of AILT by PCR for the presence of TCR clonality.
  • The results of this study emphasise that TCR clonality and oligoclonality is a diagnostic feature of AILT and that BV17S1 is over-represented with no other common molecular findings.

  • [Title] Allogeneic stem cell transplantation is able to induce long-term remissions in angioimmunoblastic T-cell lymphoma: a retrospective study from the lymphoma working party of the European group for blood and marrow transplantation.
  • PURPOSE: To analyze the long-term outcome in terms of nonrelapse mortality (NRM), relapse rate (RR), progression-free survival (PFS), and overall survival (OS) in patients with angioimmunoblastic T-cell lymphoma (AITL) treated with allogeneic stem-cell transplantation (alloSCT).
  • Median age was 48 years (range, 23 to 68 years), 34 patients had received > or = two lines of chemotherapy before alloSCT, and 11 patients had experienced treatment failure with a prior autologous stem-cell transplantation.
  • Twenty-seven patients were allografted in chemotherapy-sensitive disease, and 18 were allografted in refractory disease.
  • RR was estimated as 16% and 20% at 2 and 3 years, respectively, and was lower in patients developing chronic graft-versus-host disease (cGVHD).
  • Both the lower RR after transplantation as well as the decreased RR in patients developing cGVHD after the alloSCT suggests the existence of a clinically relevant graft-versus-lymphoma effect.

  • BACKGROUND AND OBJECTIVES: Angioimmunoblastic T-cell lymphoma (AILT) is a peripheral T-cell tumor of unknown etiology with variable biological and clinical presentations.
  • Previous clonality studies have shown heterogeneous clonal restrictions of B- and T-cell populations in this tumor.
  • AILT is characterized by the presence of increased numbers of Epstein-Barr virus (EBV) infected cells.
  • DESIGN AND METHODS: Frozen material from 59 cases of AILT was used for DNA isolation and gene analysis by Southern blotting.
  • Survival rate did not correlate with either T-cell clonality (p=0.84), or presence of EBV-infected cells (p=0.84).
  • The EBV-DNA copy number in EBV-infected tissue did not correlate with disease progression (p=0.87).
  • The survival rate and clinical status according to the international prognostic index (IPI) did not correlate with T-cell clonality status or EBV infection.
  • INTERPRETATION AND CONCLUSIONS: AILT remains a heterogeneous disease with clinical behavior that varies irrespective of the genomic parameters investigated.

  • [Title] Angioimmunoblastic T-Cell lymphoma: a critical analysis of clinical, morphologic and immunophenotypic features.
  • BACKGROUND: Angioimmunoblastic T-cell lymphoma (AITL), a subtype of peripheral T-cell lymphoma (PTCL), is characterized by unique clinical and biological features.
  • Its diagnosis remains a challenge as clinical presentation as well as pathologic findings are frequently misleading.
  • Common clinical features included generalized lymphadenopathy (60%), hepatomegaly (70%), splenomegaly (50%), anemia (80%) and polyclonal hypergammaglobulinemia (100%).
  • Absence of follicles, polymorphous infiltrate, extra-follicular follicular dendritic cell (FDC) proliferation, high endothelial venules (HEV) prominence and neoplastic T-cells were the diagnostic features of AITL.
  • CONCLUSION: Awareness of various morphological and immunophenotypic complexities of AITL and distinction from reactive adenopathies and other types of lymphomas that mimic AITL is underscored in this study.

  • [Title] Therapy of peripheral T/NK neoplasms.
  • The mature T/natural killer (NK) lymphoma/leukemias represent 5-15% of all non-Hodgkin lymphoma.
  • These diseases have a geographic variation, with more nodal disease in North America and Europe, including peripheral T cell lymphomas, unspecified, anaplastic large cell lymphoma, and angioimmunoblastic T cell lymphoma; and more extranodal disease in Asia due to Epstein-Barr virus-related nasal NK/T lymphoma and human T-cell leukemia virus (HTLV)-1-associated adult T cell leukemia/lymphoma.
  • The prognosis in most peripheral T/NK neoplasms is poor, with 5-year survival less than 30%.
  • Progress has been slow due to the rarity of the diseases, geographic variation, relative chemoresistance, and lack of randomized trials.
  • In this review, topics include the question of CHOP as standard therapy, prognostic factors, disease-adapted therapy, novel approaches, monoclonal antibody therapy, and stem cell transplantation.

  • Campath-1H or alemtuzumab, a human anti-CD52, has been shown to be effective in T-cell malignancies; however, there is very limited information on CD52 expression in T-cell lymphoma (TCL).
  • Fourteen cases of angioimmunoblastic T-cell lymphoma (AITL) were excluded as there were no reliable criteria to differentiate whether the CD52-positive cells were neoplastic T-cells, which are usually small-sized, or the usually abundant, small-to-large residual/reactive B-cells in this lymphoma sub-type.
  • In the remaining 83 tumors, CD52 was expressed in 29 (35%) tumors including 8/17 (47%) NK/T-cell lymphomas, 14/35 (40%) unspecified peripheral TCLs and 4/18 (22%) anaplastic large cell lymphomas.

  • [Title] Angioimmunoblastic T-cell lymphoma: clinical and laboratory features at diagnosis in 77 patients.
  • We retrospectively analyzed 77 patients with pathologically diagnosed angioimmunoblastic T-cell lymphoma from a single city.
  • Average time between first symptoms of the disease and diagnosis was 3.6 months.
  • At diagnosis, peripheral nodes were present in all but 1 patient, and were generalized in 90% of cases.
  • Other clinical manifestations included pleuritis (22%); arthralgia or arthritis (17%); ear, nose, and throat involvement (14%); central or peripheral neurologic manifestations (10%); and ascites (5%).
  • Most patients presented with advanced disease at diagnosis (bone marrow involvement in 60% of cases).
  • Auto- or disimmune manifestations were reported in one-third of patients: autoimmune hemolytic anemia was present at diagnosis in 19% of patients and thrombocytopenic purpura in 7%.
  • Clonality was analyzed in lymph nodes in 47 patients: T-cell and B-cell clones were found in 45 (96%) and 20 (45%) patients, respectively.
  • The current study underlines the diversity of presenting manifestations of angioimmunoblastic T-cell lymphoma.

  • [Title] Evaluation of FoxP3 expression in peripheral T-cell lymphoma.
  • Peripheral T-cell lymphomas (PTCLs) are biologically heterogeneous and have not been successfully correlated with specific T-cell subsets.
  • We investigated PTCL, not otherwise specified (NOS), angioimmunoblastic T-cell lymphoma (AILT), and anaplastic large cell lymphoma (ALCL) cases for FoxP3 expression to determine a potential derivation from regulatory T (Treg) cells.
  • One PTCL-NOS case strongly expressed FoxP3 in the neoplastic T cells and showed unusual histomorphologic features with a dense infiltration of the lymph node by immunoblastic T cells and almost no reactive background infiltrate.
  • The patient died shortly after diagnosis, suggesting that biologic properties of Treg cells may have contributed to the rapidly fatal clinical course.
  • All remaining PTCL-NOS and AILT cases showed FoxP3 positivity only in the reactive infiltrate.
  • FoxP3+ PTCL-NOS presumably derived from bona fide Treg cells occurs but seems rare in the Western population.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] The usefulness of flow cytometric CD10 detection in the differential diagnosis of peripheral T-cell lymphomas.
  • We studied the histologic and multiparameter flow cytometry (MFC) features of 12 cases of angioimmunoblastic T-cell lymphoma (AITL), 13 of mature T-cell lymphoma, and 25 control cases of reactive lymphoid hyperplasia to evaluate the role of CD10 in the differential diagnosis of peripheral T-cell lymphomas (PTCLs).
  • Mature T-cell lymphoma showed a more heterogeneous altered immunophenotypic pattern, and 2 cases of PTCL, unspecified, had clear evidence of aberrant CD10 expression on T cells.
  • A small physiologic CD3+/CD4+/CD10+ T-cell population was detected by MFC in all control cases tested (range, 0.28%-4.71%), suggesting that a normal subset of peripheral CD10+ T cells exists.
  • CD10 was a highly sensitive but incompletely specific phenotypic marker for diagnosing AITL; the differential diagnosis of PTCL, unspecified, must be related with traditional histologic features.

  • [Title] [Clinicopathologic features and diagnosis of 18 patients with angioimmunoblastic T-cell lymphoma].
  • OBJECTIVE: To explore the clinical and pathologic features of angioimmunoblastic T-cell lymphoma(AITL) and provide evidence for diagnosis.
  • RESULTS: Characteristic features at the presentation of AITL included generalized lymphadenopathy, fever, splenomegaly, and skin rashes with polyclonal hyper-gammaglobulinemia and other hematological abnormalities (such as Coombs-positive hemolytic anemia), which often involved the bone marrow and had well-described histologic features.
  • CONCLUSION: Repeated lymphadenbiopsy is helpful for AITL diagnosis.
  • Routine histological and immunohistochemical examinations (especially including CXCL13) play significant role in the diagnosis and differential diagnosis of AITL.
