    Full Text Available INTRODUCTION: Lymphomas are heterogeneous group of malignant lympho-proliferative disorders. Broadly categorized into Non-Hodgkin’s lymphoma [NHLs] and Hodgkin’s lymphoma [HL]. Decades back one of the challenging topics in morphologic pathology was accurate diagnosis and classification of lymphoma. Studies on lymphoma with clinicopathologic correlation were found to be much significant. STUDY OBJECTIVES: This was a retrospective study aimed to describe lymphomas on histo morphology and thus classify NHLs using working formulation for clinical usage (1982 and HL using Rye (1966 classification respectively. To attempt clinicopathologic correlation. METHODS: The study was done in the department of pathology, Mahadevappa Rampure Medical College, Gulbarga during the period 1989-1999. Formalin fixed paraffin wax embedded tissue blocks previously diagnosed as lymphomas in the department were used. Morphologic details by light microscopy on haematoxylin and eosin (H&E stained sections were noted. Clinical history of each case were analysed from hospital records. Clinical and pathologic correlation was done. Special stains Reticulin (Gomori and Periodic acid Schiff’s stain [PAS] was done in relevant cases. RESULTS: Study of total 102 cases of lymphoma it was observed NHLs formed 70 cases with an incidence of 68.3%. HL accounted for 32 cases with incidence of 37.2%. NHLs commonly presented in fifth decade 24.2%, followed by fourth and sixth decade. Sex distribution showed Male: Female ratio as 2.5:1. Majority of cases presented with cervical and axillary lymphadenopathy at 41% and 20% respectively. The most frequent grade was clinically aggressive intermediate grade NHLs seen in 80% of all cases. 20 cases of NHLs were of extranodal in origin. The most common site was gastrointestinal tract (60% and head and neck region with (30%. The major histologic type in both nodal and extranodal NHLs was diffuse small cleaved cell type (DSCC. HL showed sex

    Composite lymphomas consist of 2 or more distinct lymphomas occurring in a single anatomical site or simultaneously in different sites and can be composed of any combination of B-cell non-Hodgkin lymphoma (NHL), T-cell NHL, or Hodgkin lymphoma (HL). Cases of composite lymphomas with more than 2 lymphomas are extremely rare, with only 4 reports in the literature. We report the case of a 49-year-old man with a triple composite lymphoma in a single lymph node, consisting of small lymphocytic lymphoma, follicular lymphoma, and mantle cell lymphoma in situ. The patient received multiple courses of chemotherapy and an autologous stem cell transplant, which resulted in complete remission. Then, 6 years after the stem cell transplant, he developed classical HL. This unique case is, to our knowledge, the first report of a patient with triple composite lymphoma consisting of 3 small mature B-cell NHLs, who subsequently developed a fourth lymphoma.

    In a recent Nature article, Morin et al. uncovered a novel role for chromatin modification in driving the progression of two non-Hodgkin lymphomas (NHLs), follicular lymphoma and diffuse large B-cell lymphoma. Through DNA and RNA sequencing of 117 tumor samples and 10 assorted cell lines, the authors identified and validated 109 genes with multiple mutations in these B-cell NHLs. Of the 109 genes, several genes not previously linked to lymphoma demonstrated positive selection for mutation including two genes involved in histone modification, MLL2 and MEF2B.

    Full Text Available Extranodal non-Hodgkin’s lymphomas (NHLs represent up to 30-40% of all NHL cases. The gastrointestinal tract is the most commonly involved extranodal site; accounting for about half of such cases [1]. Stomach and the small intestine constitute the most common gastrointestinal sites. Secondary invasion of the pancreas from contiguous, retroperitoneal lymph node disease is the prevalent mode of involvement. Secondary involvement of the pancreas from the duodenum or adjacent peripancreatic lymphadenopathy is well-known. Primary pancreatic lymphoma (PPL is an extremely rare disease [2]. PPL can present as an isolated mass mimicking pancreatic carcinoma. However, unlike carcinomas, PPL are potentially treatable [3].

    With approximately 10000 cases per year in France, non-Hodgkin's lymphoma (NHL) represents the most frequent hematological malignancy, and 5 to 10 % of new cases of cancers. NHLs constitute a heterogeneous group of lympho-proliferative diseases, including entities with very different epidemiological and evolutive characteristics, as well as prognosis and treatments. Several classifications exist, but in practice, we individualize aggressive NHL including Diffuse Large B-Cell Lymphomas (DLBCL) which is the most common lymphoma, and indolent NHL including follicular lymphomas and mucosa-associated lymphoid tissue (MALT) lymphomas. The role of the radiotherapy in the management of NHLs varies according to the specific sub-type of lymphoma, but it has become increasingly limited over time. Overall it finds indications with curative intent only in situations of localized LMNH: either associated with chemotherapy as part of a combined modality therapy as for the treatment of localized DLBCL, or as exclusive treatment specially in the rare situations of localized follicular lymphomas. Moreover, lymphocytes being extremely radiosensitive cells, radiotherapy retains excellent indications with palliative intent for the management of symptomatic bulky tumor masses, and that whatever the sub-type of NHLs may be. It is important to remember that even today the 'Involved Field' irradiation type remains the gold standard for the treatment of nodal NHLs, even if we witness at present the emergence of new types of irradiation, which aim to reduce the amount of irradiated tissues to try to limit the risks of delayed radio-induced complications. The purpose of this article is to clarify the specific aspects (epidemiological, radio-anatomical and prognostic characteristics) of each NHLs'sub-types (except primary central nervous system lymphomas), as well as the practical modalities of the irradiation (illustrated by a clinical case record) when an indication of

    To evaluate the value of computed tomography (CT)-guided core needle biopsy in diagnosis of primary pulmonary lymphoma and its subtypes. A retrospective analysis of the records of all patients with primary pulmonary lymphoma between January 2005 and August 2011 was performed. There were 25 patients referred to the radiology department for CT-guided core needle biopsy. The success rate and complications were assessed. A definitive diagnosis and accurate histologic subtype were obtained in 21 patients with a success rate of 84.0%. Diagnosis was made in the other four patients with bronchoscopy and surgery. Non-Hodgkin lymphoma (NHL) was the diagnosis in all patients. Most subtypes were mucosa-associated lymphoid tissue (MALT) lymphomas (n = 19). The remaining subtypes included three diffuse large B-cell NHLs, two peripheral T-cell lymphomas not otherwise specified, and one anaplastic large cell NHL. The success rate of core needle biopsy was 95% (18 of 19) for MALT lymphomas, 67% (2 of 3) for diffuse large B cell NHLs, and 33% (1 of 3) for other NHLs. The success rate for MALT lymphomas was significantly higher than that of non-MALT lymphomas according to Fisher exact t test (P = .031). No serious complications occurred in any patients. CT-guided core needle biopsy is a reliable procedure to assist in diagnosis and classification of primary pulmonary lymphomas, especially MALT lymphomas. Copyright © 2013 SIR.

    Full Text Available The non-Hodgkin lymphomas (NHLs are a heterogeneous family of lymphoid malignancies that are among the most common neoplasms of both dogs and humans. Owing to shared molecular, signaling, incidence, and pathologic features, there is a strong framework supporting the utilization of canine lymphoma as a comparative, large animal model of human NHL. In alignment with the biologic similarities, the current approach towards the diagnosis and classification of canine lymphoma is based upon the human World Health Organization guidelines. While this approach has contributed to an increasing appreciation of the potential biological scope of canine lymphoma, it has also become apparent that the most appropriate diagnostic philosophy must be multimodal, namely by requiring knowledge of microscopic, immunophenotypic, and clinical features before establishing a final disease diagnosis. This review seeks to illustrate the comparative similarities and differences in the diagnosis of canine lymphoma through the presentation of the microscopic and immunophenotypic features of its most common forms.

    Enolases are glycolytic enzymes responsible for the ATP-generated conversion of 2-phosphoglycerate to phosphoenolpyruvate. In addition to the glycolytic function, Enolase 1 (ENO1) has been reported up-regulation in several tumor tissues. In this study, we investigated the expression and biologic function of ENO1 in Non-Hodgkin's Lymphomas (NHLs). Clinically, by western blot analysis we observed that ENO1 expression was apparently higher in diffuse large B-cell lymphoma than in the reactive lymphoid tissues. Subsequently, immunohistochemical staining of 144 NHLs suggested that the expression of ENO1 was significantly lower in the indolent lymphomas compared with the progressive lymphomas. Further, we identified ENO1 as an independent prognostic factor, and it was significantly correlated with overall survival of NHL patients. In addition, we found that ENO1 could promote cell proliferation, regulate cell cycle associated gene and PI3K/AKT signaling pathway in NHLs. Finally, we verified that ENO1 participated in the process of lymphoma cell adhesion mediated drug resistance (CAM-DR). Adhesion to FN or HS5 cells significantly protected OCI-Ly8 and Daudi cells from cytotoxicity compared with those cultured in suspension, and these effects were attenuated when transfected with ENO1-siRNA. Based on the study, we propose that inhibition of ENO1 expression may be a novel strategy for therapy for NHLs patients, and it may be a target for drug resistance. - Highlights: • ENO1 expression is reversely correlated with clinical outcomes of patients with NHLs. • ENO1 promotes the proliferation of NHL cells. • ENO1 regulates cell adhesion mediated drug resistance.

    Full Text Available Diane Coso, Sylvain Garciaz, Réda BouabdallahDepartment of Hematology, Cancer Center Institut J. Paoli-I. Calmettes, University of La Méditerranée, Marseille, FranceAbstract: Non-Hodgkin lymphomas (NHLs are one of the most frequent malignancies in adolescents and young adults (AYA. Among NHLs, Burkitt's lymphoma (BL represents approximately 40% while diffuse large B-cell lymphoma (DLBCL accounts for nearly 20% of cases. Primary mediastinal B-cell lymphoma is a variant of DLBCL, which preferentially concerns young patients. Biology of B-NHLs is well known and several pathways involving chromosomal translocations, gene rearrangements, and molecular profiling are the subject of continuous investigations. AYA with B-NHL have inferior survival when compared with children. The reasons for this unfavorable outcome are multifactorial, but disease-related biological characteristics of the tumor represent a powerful factor influencing survival. The choice of optimal strategy in the management of B-NHL in patients of 15–29 years old remains controversial and depends on the treating institution and its physicians. Although children and younger adolescents benefit from pediatric approaches using intensive treatment, older adolescents are often treated with adult rituximab-based chemotherapy. In this review, we focus on the current knowledge relevant to AYA with DLBCL and primary mediastinal B-cell lymphoma.Keywords: DLBCL, PMBCL, AYA, prognosis, treatment

    We have shown that human B-cell non-Hodgkin lymphomas (B-NHLs) express heat shock protein (HSP)H1/105 in function of their aggressiveness. Here, we now clarify its role as a functional B-NHL target by testing the hypothesis that it promotes the stabilization of key lymphoma oncoproteins. HSPH1 silencing in 4 models of aggressive B-NHLs was paralleled by Bcl-6 and c-Myc downregulation. In vitro and in vivo analysis of HSPH1-silenced Namalwa cells showed that this effect was associated with a significant growth delay and the loss of tumorigenicity when 10(4) cells were injected into mice. Interestingly, we found that HSPH1 physically interacts with c-Myc and Bcl-6 in both Namalwa cells and primary aggressive B-NHLs. Accordingly, expression of HSPH1 and either c-Myc or Bcl-6 positively correlated in these diseases. Our study indicates that HSPH1 concurrently favors the expression of 2 key lymphoma oncoproteins, thus confirming its candidacy as a valuable therapeutic target of aggressive B-NHLs.

  15. Infectious agents as causes of non-Hodgkin lymphoma.

    Science.gov (United States)

    Engels, Eric A

    2007-03-01

    Among exposures presently viewed as possible etiologic factors in non-Hodgkin lymphoma (NHL), infections are close to being regarded as established causes. Infectious agents causing NHL can be classified, according to mechanism, into three broad groups. First, some viruses can directly transform lymphocytes. Lymphocyte-transforming viruses include Epstein Barr virus (linked to Burkitt's lymphoma, NHLs in immunosuppressed individuals, and extranodal natural killer/T-cell NHL), human herpesvirus 8 (primary effusion lymphoma), and human T lymphotropic virus type I (adult T-cell leukemia/lymphoma). Second, human immunodeficiency virus is unique in causing profound depletion of CD4+ T lymphocytes, leading to acquired immunodeficiency syndrome and an associated high risk for some NHL subtypes. Third, recent evidence suggests that some infections increase NHL risk through chronic immune stimulation. These infections include hepatitis C virus as well as certain bacteria that cause chronic site-specific inflammation and seem to increase risk for localized mucosa-associated lymphoid tissue NHLs. Establishing that an infectious agent causes NHL depends on showing that the agent is present in persons with NHL as well as laboratory experiments elucidating the mechanisms involved. Only epidemiologic studies can provide evidence that infection is actually a risk factor by showing that infection is more frequent in NHL cases than in controls. Given the range of mechanisms by which infections could plausibly cause NHL and our growing molecular understanding of this malignancy, this field of research deserves continued attention.

    Non-Hodgkin's lymphoma (NHL) affecting the ethmoid sinus and epiglottis is uncommon. Furthermore, synchronous NHLs involving the ethmoid sinus and epiglottis are extremely rare and have not been reported previously. This article reports synchronous, primary, diffuse, large B-cell lymphoma (DLBCL) arising in the ethmoid sinus and epiglottis, which was successfully treated by immunochemotherapy. A careful examination of the head and neck is necessary to determine the existence of multiple synchronous primary tumors, because primary synchronous occurrence of DLBCL in the head and neck is unusual and can impact the prognosis adversely.

    Kaposi sarcoma-associated herpesvirus (KSHV) is known to be associated with two distinct lymphoproliferative disorders: primary effusion lymphoma (PEL) and multicentric Castleman disease (MCD)/MCD-associated plasmablastic lymphoma. We here report a high incidence of KSHV infection in solid HIV-associated immunoblastic/plasmablastic non-Hodgkin's lymphomas (NHLs), in patients lacking effusions and without evidence of (prior) MCD. Within a cohort of 99 HIV-related NHLs, 10 cases were found to be KSHV positive on the basis of immunostaining for KSHV LNA-1 as well as KSHV-specific polymerase chain reaction. All but one of the tumors coexpressed Epstein-Barr virus. Interestingly, all KSHV-positive cases belonged to a distinctive subgroup of 26 diffuse large B-cell lymphomas characterized by the expression of CD138 (syndecan-1) and plasmablastic/immunoblastic morphology. These KSHV-positive lymphomas were preceded by Kaposi sarcoma in 60% of the patients and involved the gastrointestinal tract in 80%. Our results indicate that KSHV infection is not restricted to PEL and MCD; it is also common (38%) in HIV-related solid immunoblastic/plasmablastic lymphomas.

Because of the rarity and heterogeneity of these diseases, large clinical trials have not been conducted and optimal therapy is not well defined. Most subtypes are treated with similar combination chemotherapy regimens as used for aggressive B-cell NHL, but with poorer outcomes. New treatment combinations and novel agents are currently being explored for PTCLs and this review highlights a number of options that appear promising.Keywords: treatment, non-Hodgkin’s lymphoma, novel therapy, natural-killer cells

    2013-12-01

    The risk of CNS dissemination and CNS prophylaxis strategies in aggressive non-Hodgkin lymphoma (NHL) is still debated. CNS dissemination is a rare but fatal event. A CNS prophylaxis is common for Burkitt and B-cell lymphoblastic lymphoma; however, in other NHLs, prophylactic treatments are not systematically warranted. Current risk models showed low sensitivity in predicting CNS involvement, implying overtreatment in roughly 70% of high-risk patients. Risk models in the rituximab era were modulated for the detection of occult CNS disease at diagnosis using flow cytometry. The optimal regimen for CNS prophylaxis in aggressive lymphoma patients has not been established thus far and should be modulated at different levels of 'intensity' such as standard intrathecal chemotherapy, 'active' intrathecal chemotherapy with liposomal cytarabine or more aggressive systemic treatment with high doses of drugs having good CNS bioavailability reserved for patients who are truly at high risk of CNS dissemination.

    We examined a possible role for the adhesion molecules LFA-1 and ICAM-1 in localizing central nervous system non-Hodgkin's lymphomas (CNS-NHLs) to the brain. Fresh frozen sections from 12 monoclonal CNS NHLs (11 primary, one secondary) were stained with monoclonal antibodies to LFA-1 alpha chain (CD11a), beta chain (CD18) and, ICAM-1 (CD54). Additional staining made use of rat monoclonal antibodies to the human and mouse high endothelial venule antigens HECA 452 and MECA 79 and mouse ICAM-1. The expression of these same molecules was also studied in mice with severe combined immunodeficiency (SCID) mice, bearing intracranial human lymphoblastoid cells. Eleven of the CNS-NHL tumors expressed LFA-1 alpha (one strongly, one intermediate, nine weakly). Nine of the tumors weakly expressed LFA-1 beta.. Nine of twelve tumors weakly expressed ICAM-1. In six of seven tumors definite blood vessels stained for ICAM-1. Non-tumor brain from two patients and non-tumor cerebral blood vessels showed no staining with CD11a, CD18 or CD54 antibodies. Strong expression of LFA-alpha and LFA-beta as well as ICAM-1 was noted in human lymphoblastoid cells (LCLs)/SCID mouse CNS lymphomas. Tumor blood vessels in these mice stained for mouse ICAM-1. Normal SCID mouse brains showed no staining with CD11a, CD18, CD54 or mouse ICAM-1 antibodies. Human, human/mouse CNS lymphomas, normal human, and mouse brains showed no staining with either HECA 452 or MECA 79.(ABSTRACT TRUNCATED AT 250 WORDS)

    Non-Hodgkin lymphomas (NHLs) include a heterogeneous group of diseases, which differ in both cellular origin and clinical behavior. Among the aggressive malignancies of this group, the diffuse large B-cell lymphomas (DLBCLs) are the most frequently observed. They are themselves clinically and molecularly heterogeneous and have been further sub-divided in three sub-types according to different cell of origin, mechanisms of oncogenesis and clinical outcome. Among them, the germinal center B-cell-like (GCB) derives from the germinal center and expresses the BCL6 oncogene. We have previously shown that Patz1-knockout mice develop B-cell neoplasias, suggesting a tumor suppressor role for PATZ1 in human NHLs. Here, by immunohistochemical analysis of a tissue-microarray including 170 NHLs, we found that PATZ1 nuclear expression is down-regulated in follicular lymphomas and DLBCLs. Moreover, consistent with our previous results showing a PATZ1-dependent regulation of BCL6 and BAX transcription, we show that low PATZ1 nuclear expression significantly correlates with high BCL6 expression, mainly in DLBCLs, and with low BAX expression, also considering separately follicular lymphomas and DLBCLs. Finally, by analyzing overall and progression-free survival in DLBCL patients that underwent rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy, low levels of PATZ1 were significantly associated to a worst outcome and demonstrated an independent prognostic factor in multivariate analysis, including known prognostic factors of DLBCL, IPI score and cell of origin (GCB/non-GCB). Therefore, we propose PATZ1 as a new prognostic marker of DLBCLs, which may act as a tumor suppressor by enhancing apoptosis through inhibiting and enhancing transcription of BCL6 and BAX, respectively.

    Non-Hodgkin's lymphomas (NHLs) comprise a large and diverse group of neoplasms of lymphocyte origin with heterogeneous molecular features and clinical manifestations. Current therapies are based on standard chemotherapy, immunotherapy, radiation or stem cell transplantation. The discovery of recurrent mutations in epigenetic enzymes, such as chromatin modifiers and DNA methyltransferases, has provided researchers with a rationale to develop novel inhibitors targeting these enzymes. Several clinical and preclinical studies have demonstrated the efficacy of epigenetic drugs in NHL therapy and a few specific inhibitors have already been approved for clinical use. Here, we provide an overview of current NHL classification and a review of the present literature describing epigenetic alterations in NHL, including a summary of different epigenetic drugs, and their use in preclinical and clinical studies.

    Marco Gunnellini

    2012-01-01

    Full Text Available Mantle cell lymphoma (MCL comprises 3–10% of NHL, with survival times ranging from 3 and 5 years. Indolent lymphomas represent approximately 30% of all NHLs with patient survival largely dependent on validated prognostic scores. High response rates are typically achieved in these patients with current first-line chemoimmunotherapy. However, most patients will eventually relapse and become chemorefractory with poor outcome. Alternative chemoimmunotherapy regimens are often used as salvage strategy and stem cell transplant remains an option for selected patients. However, novel approaches are urgently needed for patients no longer responding to conventional chemotherapy. Lenalidomide is an immunomodulatory drug with activity in multiple myeloma, myelodisplastic syndrome and chronic lymphoproliferative disorders. In phase II studies of indolent NHL and MCL lenalidomide has shown activity with encouraging response rates, both as a single agent and in combination with other drugs. Some of these responses may be durable. Optimal dose of lenalidomide has not been defined yet. The role of lenalidomide in the therapeutic armamentarium of patients with indolent NHL or MCL will be discussed in the present paper.

    HIV-infected persons treated with highly active antiretroviral therapy (HAART) continue to have elevated risk for non-Hodgkin lymphoma (NHL). We conducted a retrospective cohort study of NHL among patients at an urban HIV clinic (N=3025). Proportional hazards models identified immunologic and virologic predictors of NHL. Sixty-five NHLs arose during 1989-2006. NHL incidence declined over time. Nonetheless, 51 NHLs (78%) occurred within the HAART era (1996-2006). NHL risk increased with declining CD4 count (p-trend<0.0001) and increasing HIV viral load (p-trend=0.005). In a multivariable model, NHL risk was independently associated with both current CD4 count (hazard ratios 7.7 and 3.8, respectively, for CD4 counts 0-99 and 100-249 vs. 250+ cells/mm3; p-trend<0.0001) and prior time spent with a viral load above 5.00 log10 copies/ml (hazard ratios of 3.4, 2.6, and 6.8, respectively, for 0.1-0.4, 0.5-1.4, and 1.5+ years vs. 0 years; p-trend=0.004). Although serum globulin levels were elevated compared to the general population, NHL risk was unrelated to this B-cell activation marker (p=0.39). Among HIV-infected individuals in the HAART era, NHLs are linked to immunosuppression and extended periods of uncontrolled HIV viremia. The association with high-level viremia could reflect detrimental effects on immune function related to incompletely effective HAART or direct effects on B-cells. PMID:20418723

    Mutation of the p53 gene has been associated with treatment failure and poor outcome in various malignancies. It has been suggested that immunohistochemical analysis of p53 and p21Waf1, a downstream target, can be used to screen for p53 gene mutations. We determined the value of immunohistochemical...... screening for p53 gene mutations as a prognostic marker in a population-based group of B- and T-cell non-Hodgkin's lymphomas (NHLs). On the basis of p53 gene mutation status and immunohistochemically detected p53 and p21Waf1 expression in 34 lymphomas, we established an immunophenotype (delta p53......) correlating with p53 gene mutation. The immunohistochemical analysis was extended to encompass 199 lymphomas from a population-based registry and was correlated with clinical parameters. Delta p53 showed 100% concordance with p53 gene mutation and was detected in 42 cases (21%). Multivariate analysis...

    The relative distribution of non-Hodgkin lymphoma (NHL) subtypes differs markedly around the world. The aim of this study was to report this distribution in Algeria. A panel of four hematopathologists classified 197 consecutive cases according to the World Health Organization classification, including 87.3% B-cell and 12.7% T- or natural killer (NK)-cell NHLs. This series was compared with similar cohorts from Western Europe (WEU) and North America (NA). Algeria had a significantly higher frequency of diffuse large B-cell lymphoma (DLBCL: 52.8%) and a lower frequency of follicular lymphoma (FL: 13.2%) compared with WEU (DLBCL: 32.2%; FL: 20.0%) and NA (DLBCL: 29.3%; FL: 33.6%). The frequency of mantle cell lymphoma was lower in Algeria (2.5%) compared with WEU (8.3%). Smaller differences were also found among the NK/T-cell lymphomas. In conclusion, we found important differences between Algeria and Western countries, and further epidemiologic studies are needed to explain these differences.

    Full Text Available Abstract Background Primary Non-Hodgkin's Lymphoma (PHNL of the breast is a rare entity, while secondary involvement of the breast with diffuse disease of Non-Hodgkin's lymphoma (NHL is more common. However, PNHL is the most frequent haematopoietic tumour of the breast. Diagnostic criteria for PNHL of the breast are presence of technically adequate pathologic specimens, close association of mammary tissue and lymphomatous infiltrate, no prior diagnosis of an extarammamary lymphoma, and no evidence of concurrent widespread disease, except for ipsilateral axillary lymph nodes if concomitant with the primary lesion. Case presentation A 57-year-old woman was recalled because her screening mammograms revealed three separate lesions in her right breast and one in the left. Histology of the lesions confirmed lymphoma in one breast with ductal carcinoma in the other. Conclusion Most of reported cases in literature have been involving the right breast, and almost all the patients were females. NHLs of the breast typically present as unilateral mass; the frequency of bilateral disease at first presentation ranges from 5–25%. Our objective is to report a case of primary lymphoma of the breast involving both axillae with concomitant bilateral primary breast cancer which has not been reported yet to our best of knowledge in literature.

    Full Text Available Gastrointestinal lymphomas represent 5-20% of extra nodal lymphomas and mainly occur in the stomach and small intestine. Clinical findings are not specific, thus often determining a delay in the diagnosis. Imaging features at conventional and cross-sectional imaging must be known by the radiologist since he/she plays a pivotal role in the diagnosis and disease assessment, thus assisting in the choice of the optimal treatment to patients. This review focuses on the wide variety of imaging presentation of esophageal, gastric, and small and large bowel lymphoma presenting their main imaging appearances at conventional and cross-sectional imaging, mainly focusing on computed tomography and magnetic resonance, helping in the choice of the best imaging technique for the disease characterization and assessment and the recognition of potential complications. Gastrointestinal tract is the most common extra nodal site involved by lymphoma. Although lymphoma can involve any part of the gastrointestinal tract .The most frequent sites in order of its occurrence are the stomach followed by small intestine and ileocecal region. Gastrointestinal tract lymphoma is usually secondary to the widespread nodal diseases and primary gastrointestinal tract lymphoma is relatively rare. [Int J Res Med Sci 2016; 4(6.000: 2481-2486

  14. Gastric infiltration of diffuse large B-cell lymphoma: Endoscopic diagnosis and improvement of lesions after chemotherapy

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Diffuse large B-cell lymphoma (DLBCL) is the most common histologic subtype of the non-Hodgkin's lymphoma (NHL) accounting for about 40% of all NHLs. This is a case report about the endoscopic appearance of a DLBCL with infiltration to the stomach in a 39-year-old female. She had a 6-me history of lumbar and left upper quadrant pain with intermittent episodes of melena. A computer tomograghy (CT) scan showed mural thickening of the gastric antrum. Endoscopic examination revealed multiple gastric ulcers. Definite diagnosis could be made by endoscopic biopsies and the patient had a good response to chemotherapy. This response correlated well with a further endoscopic follow-up. A follow-up endoscopic examination could be considered to evaluate a good response to chemotherapy in DLBCL patients with secondary gastric dissemination.

    2014-01-01

    Context Given the higher risk of AIDS-defining malignancies that include Kaposi sarcoma (KS), certain non-Hodgkin lymphomas (NHLs), and cervical cancer in persons with human immunodeficiency virus (HIV) infection, the HIV epidemic has likely contributed to the overall numbers of these cancers in the United States. Objective To quantify the proportions of KS, AIDS-defining NHLs, and cervical cancer in the United States that occurred among persons with AIDS from 1980 to 2007. Design, Setting, and Participants The HIV/AIDS Cancer Match Study (1980–2007) linked data from 16 US HIV/AIDS and cancer registries to identify cases with and without AIDS for KS, AIDS-defining NHLs (ie, diffuse large B-cell lymphoma [DLBCL], Burkitt lymphoma [BL], and central nervous system [CNS] lymphoma), and cervical cancer. Using linked data, we derived cancer rates for persons with and without AIDS. To estimate national counts, the rates were applied to national AIDS surveillance and US Census data. Main Outcome Measure Proportion of AIDS-defining malignancies in the United States occurring in persons with AIDS. Results In the United States, an estimated 79.0% (95% confidence interval [CI], 78.6%–79.4%) of 85 922 KS cases, 5.5% (95% CI, 5.3%–5.6%) of 383 095 DLBCL cases, 19.4% (95% CI, 17.8%–21.1%) of 17 780 BL cases, 26.2% (95% CI, 25.2%–27.1%) of 28 259 CNS lymphoma cases, and 0.41% (95% CI, 0.36%–0.46%) of 386 166 cervical cancer cases occurred among persons with AIDS during 1980–2007. The proportion of KS and AIDS-defining NHLs in persons with AIDS peaked in the early 1990s (1990–1995: KS, 89.0% [95%CI, 88.6%–89.3%]; DLBCL, 9.5% [95%CI, 9.2%–9.8%]; BL, 27.4% [95% CI, 25.0%–29.7%]; and CNS lymphoma, 47.2% [95% CI, 45.7%–48.7%]; all P<.001 [compared with 1980–1989]) and then declined (2001–2007: KS, 67.0% [95% CI, 64.5%–69.4%]; DLBCL, 4.3% [95% CI, 3.9%–4.6%]; BL, 20.8% [95% CI, 17.2%–24.3%]; and CNS lymphoma, 12.3% [95% CI, 10.1%–14.4%]; all P<.001

    Full Text Available Context: There is a need to study potential infective etiologies in lymphomas. Lymphocyte-transforming viruses can directly infect lymphocytes, disrupt normal cell functions, and promote cell division. Epstein–Barr virus (EBV is known to be associated with several lymphomas, especially Hodgkin lymphomas (HLs. And recently, the lymphocyte-transforming role of hepatitis B virus (HBV has been emphasized. Aims: The aim of this study was to elucidate the association of two potentially oncogenic, widely prevalent latent DNA viruses, EBV and HBV, in non-HL (NHL. Settings and Design: In this prospective study, we estimated plasma EBV and HBV DNA in NHL patients. Materials and Methods: Peripheral blood was obtained from newly diagnosed, treatment na ïve, histologically confirmed NHL patients. Plasma EBV DNA was quantified by real-time polymerase chain reaction (PCR targeting Epstein–Barr Nucleic acid 1 while the plasma HBV DNA was detected using nested PCR targeting HBX gene. In a small subset of patients, follow-up plasma samples post-anticancer chemotherapy were available and retested for viral DNA. Results: Of the 110 NHL patients, ~79% were B-cell NHL and ~21% were T-cell NHL. Plasma EBV-DNA was detected in 10% NHLs with a higher EBV association in Burkitt lymphoma (33.3% than other subtypes. Pretherapy HBV DNA was detected in 21% NHLs; most of them being diffuse large B-cell lymphoma (DLBCL. Moreover, 42% of DLBCL patients had HBV DNA in plasma. Since all patients were HBV surface antigen seronegative at diagnosis, baseline plasma HBV-DNAemia before chemotherapy was indicative of occult hepatitis B infection. Conclusions: Our findings indicate a significant association of HBV with newly diagnosed DLBCL.

    Non-Hodgkin's lymphomas (NHLs) are a heterogeneous group of neoplasm in which 90% are B-cell lymphomas and 10% T-cell lymphomas. Although T-helper 17 (Th17) cells have been implicated to be essential in the pathogenesis of autoimmune and inflammatory diseases, its role in B-cell non-Hodgkin's lymphoma (B-NHL) remains unknown. In this study, we observed a significantly decreased frequency of Th17 cells in peripheral blood from B-NHL patients compared with healthy individuals, accompanied with increased Th1 cells. IL-17AF plasma levels were remarkably decreased in B-NHL patients, accompanied with undetectable IL-17FF and unchangeable IL-17AA. Moreover, Th17 and Th1 cells became normalized after one or two cycles of chemotherapy. Interestingly, in B-NHL, circulating Th17 cells frequencies were significantly higher in relapsed patients than those in untreated patients or normal individuals. Meanwhile, there was no statistical difference regarding the frequencies of Th1 cells between relapsed and untreated patients. Taken these data together, circulating Th17 subset immune response may be associated with the response of patients to treatment and with different stages of disease.

    Lymphomas are a heterogeneous group of neoplasms with distinct morphologic, immunologic, and cytogenetic characteristics. Overlapping morphologic and immunophenotypic features often makes accurate diagnosis difficult. Cytogenetics helps simplify the diagnostic complexities presented in transforming and progressive lymphoid malignancies. Genetic studies using technical advances such as fluorescence in situ hybridization and the newer approaches of array comparative genomic hybridization and gene expression profiling play a critical and often defining role in the diagnosis, progression, prognosis, and therapeutic stratification. This article reviews characteristic cytogenetic abnormalities in specific subtypes of lymphomas at diagnosis, disease progression, and prognosis.

    2017-01-01

    Abstract Rationale: Primary cutaneous non-Hodgkin's lymphoma (NHL) is an uncommon entity, representing 10% of all extranodal NHLs. Among all cutaneous sites, the scalp is a rare site of representation. Patient concerns: A 92-year-old Chinese man visited our hospital with a multiple-nodular huge scalp mass on the right parieto-occipital regions. The mass was of 7-month duration and progressively enlarging in size. Diagnoses: On the basis of the result of biopsy, diffuse large B-cell NHL was diagnosed. Interventions: The mass was partially resected by surgery and no further treatment was conducted due to the advanced age and poor physical status. Outcomes: The tumor relapsed in situ after 6 months and the patient died after 2 years. Lessons: This case highlighted the limited access to standard treatment options in patients with advanced age. A thorough examination is necessary to decide upon the treatment for the primary cutaneous lymphoma. PMID:28272240

    Plasmablastic lymphoma (PBL) is a rare and aggressive subtype of non-Hodgkin lymphoma that commonly occurs in human immunodeficiency virus (HIV)-positive individuals, and affects oral sites. Occasionally, it has been described in HIV-negative patients and involving non-oral sites. Pathologically, PBL is a high-grade B-cell lymphoma that displays the immunophenotype of a terminally differentiated B-lymphocyte with loss of B-cell markers (CD20) and expression of plasma-cell antigens. Epstein-Barr virus infection and MYC rearrangements are frequently observed. Treatment of PBL is challenging because of the lack of established treatment and poor outcomes, with median survival times shorter than one year. In this review, we discuss the clinical and epidemiologic spectrum of PBL as well as its distinct pathological features. Finally, we summarize the currently available approaches for the treatment of patients with PBL. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

    2015-05-01

    The B-cell receptor pathway (BCR) is aberrantly activated in select B-cell malignancies. This knowledge has allowed for the development of inhibitors of different crucial steps of this pathway. Bruton's tyrosine kinase (BTK) is a key component of BCR signaling and functions as an important regulator of multiple cell functions including differentiation, proliferation, and survival in various B-cell malignancies. Ibrutinib is a potent, selective BTK inhibitor that has shown significant activity in specific subtypes of B-cell non-Hodgkin's lymphomas (NHLs). Given the high response rates, tolerability, and acceptable toxicities, ibrutinib was recently approved by the US Food and Drug Administration (FDA) for the treatment of patients with relapsed mantle cell lymphoma and chronic lymphocytic leukemia. It is also currently being evaluated in combination with chemotherapy and as frontline therapy in B-cell NHL. This review summarizes the preclinical and clinical development of ibrutinib in the treatment of B-cell NHL. © 2015 American Society for Clinical Pharmacology and Therapeutics.

    2014-09-01

    Full Text Available Non-Hodgkin's lymphoma (NHL consists of a group of neoplasias involving mainly B cells and represents 90% of all lymphomas. The current available therapy is based on chemotherapy associated with the monoclonal antibody rituximab (Mab Thera(r, which targets the CD20 protein, present in over 80% of NHL mature B cells. Recent clinical reports show a preference for combining the benefits of immunotherapy and adjuvant chemotherapy, thus generating safe and effective alternative treatments. The current review aimed at evaluating various aspects related to the use of rituximab for NHL, highlighting the possible inhibitory mechanisms of cell proliferation, the achieved clinical results, and the expected clinical and economic outcomes of treatments. The results from clinical tests indicate the need for a better understanding of the critical mechanisms of action of this antibody, which may maximize its therapeutic efficacy. This therapy not only represents a viable option to treat most types of NHLs, especially when associated with conventional chemotherapy, but also offers cost-utility and cost-effectiveness advantages.

    Abstract Background: Plasmablastic lymphoma (PBL) is a B-cell malignancy associated with human immunodeficiency virus (HIV). PBL could also influence the HIV-negative patients. The study aimed to identify prognostic factors for survival among Chinese PBL patients. Materials and methods: Eligible patients from literature and Peking Union Medical College Hospital (PUMCH) were included in this study. Clinical characteristics and immunophenotypic data were extracted. Kaplan–Meier curve was used to describe the survival status. Cox regression was used for multivariate analysis. Results: A total of 60 Chinese PBL patients were included, including 54 patients from 36 published articles and 6 new patients that have not been reported. The median overall survival was 7 months (95% confidence interval 3.853–10.147 months). An overwhelming majority (79.31%) of the included cases were Ann Arbor stage IV patients. All the Chinese PBL patients were HIV-negative; 46.81% were Epstein-Barr virus-positive. CD38, CD138, or MUM1 was positively expressed in more than 80% of patients; CD20 expression was also found in 22.03% of cases. Kaplan–Meier curve revealed obvious differences in patient survival between patients in primary stages and advanced stages, as well as between patients with kidney involvement and those without kidney involvement. Cox regression analysis indicated that stage and age were 2 prognostic factors for patient survival. Conclusions: Advanced stage might be associated with poor prognosis among PBL HIV-negative patients in Chinese. PMID:28248855

    2016-01-01

    Acquired generalized lipodystrophy (AGL) is a rare disease thought to result from autoimmune destruction of adipose tissue. Peripheral T-cell lymphoma (PTCL) has been reported in two AGL patients. We report five additional cases of lymphoma in AGL, and analyze the role of underlying autoimmunity and recombinant human leptin (metreleptin) replacement in lymphoma development. Three patients developed lymphoma during metreleptin treatment (two PTCL and one ALK-positive anaplastic large cell lymphoma), and two developed lymphomas (mycosis fungoides and Burkitt lymphoma) without metreleptin. AGL is associated with high risk for lymphoma, especially PTCL. Autoimmunity likely contributes to this risk. Lymphoma developed with or without metreleptin, suggesting metreleptin does not directly cause lymphoma development; a theoretical role of metreleptin in lymphoma progression remains possible. For most patients with AGL and severe metabolic complications, the proven benefits of metreleptin on metabolic disease will likely outweigh theoretical risks of metreleptin in lymphoma development or progression.

Mature cell lymphomas comprised 81% of the B-cell phenotype and 19% of the T-cell phenotype. Hodgkin lymphomas represented 32% of all cases, including 87% of the classical type and 13% of nodular lymphocyte predominant type. The geographic distribution showed 38.4% of the cases in the Southeast region, 28.7% in the Northeast, 16.1% in the South, 8.8% in the North, and 8% in the Central-west region. The distribution by age groups was 15-18 years old, 33%; 11-14 years old, 26%; 6-10 years old, 24%; and 6 years old or younger, 17%. Among mature B-cell lymphomas, most of the cases were Burkitt lymphomas (65%, followed by diffuse large B-cell lymphomas (24%. In the mature T-cell group, anaplastic large cell lymphoma, ALK-positive was the most prevalent (57%, followed by peripheral T-cell lymphoma, then not otherwise specified (25%. In the group of classic Hodgkin lymphomas, the main histological subtype was nodular sclerosis (76%. Nodular lymphocyte predominance occurred more frequently than in other series. CONCLUSION: Some of the results found in this study may reflect the heterogeneous socioeconomical status and environmental factors of the Brazilian population in different regions.

    Historial aspects of the classification of large-cell lymphomas are described. Immunological characterization of the lymphomas has been made possible by identification of T and B lymphocytes according to their cell membrane surface characteristics. The pathogenesis of lymphomas has been clarified by the germinal (follicular) centre cell concepts of Lennert and Lukes and Collins. The various classifications are presented and compared. Whether these subdivisions will have any relevance in the clinical context remains to be seen.

    Understanding of the lymphoma tumor microenvironment is poised to expand in the era of next-generation sequencing studies of the tumor cells themselves. Successful therapies of the future will rely on deeper appreciation of the interactions between elements of the microenvironment. Although the phenotypic, cytogenetic, and molecular characterization of tumor cells in lymphomas has progressed faster than most other solid organ tumors, concrete advancements in understanding the lymphoma microenvironment have been fewer. This article explores the composition of the lymphoma tumor microenvironment; its role in immune surveillance, evasion, and drug resistance; and its potential role in the development of targeted therapies.

    @@ Primary breast lymphoma (PBL) is rare, accounting for 0.04%-0.50% of breast malignancies and 1.7% of extranodal lymphoma.1,2 The originally described diagnostic criteria for PBL2 remains the standard definition for this disease. These criteria are breast location as the clinical site of presentation, absence of history of previous lymphoma or evidence of widespread disease at diagnosis, close association of lymphoma with breast tissue in pathologic specimens, and involvement of ipsilateral lymph nodes if they develop simultaneously with PBL.

    Gastrointestinal tract is the most common extranodal site involved by lymphoma with the majority being non-Hodgkin type. Although lymphoma can involve any part of the gastrointestinal tract, the most frequent sites in order of its occurrence are the stomach followed by small intestine and ileocecal region. Gastrointestinal tract lymphoma is usually secondary to the widespread nodal diseases and primary gastrointestinal tract lymphoma is relatively rare. Gastrointestinal lymphomas are usually not clinically specific and indistinguishable from other benign and malignant conditions. Diffuse large B-cell lymphoma is the most common pathological type of gastrointestinal lymphoma in essentially all sites of the gastrointestinal tract, although recently the frequency of other forms has also increased in certain regions of the world. Although some radiological features such as bulky lymph nodes and maintenance of fat plane are more suggestive of lymphoma, they are not specific,thus mandating histopathological analysis for its definitive diagnosis. There has been a tremendous leap in the diagnosis, staging and management of gastrointestinal lymphoma in the last two decades attributed to a better insight into its etiology and molecular aspect as well as the knowledge about its critical signaling pathways.

    Full Text Available Purpose: To report a case of bilateral primary intraocular lymphoma. Case report: A 33-year-old man presented with bilateral blurred vision since two years ago. Examination revealed large keratic precipitates, anterior chamber reaction, posterior subcapsular cataracts, and vitreous infiltration. After a short trial of topical and periocular steroids, diagnostic 25-gauge pars plana vitrectomy was performed and cytologic evaluation of the aspirate confirmed a diagnosis of intraocular lymphoma. The patient was subsequently managed with intravitreal methotrexate in both eyes and responded favorably. Central nervous system workup for lymphoma was negative. Conclusion: Primary intraocular lymphoma should be considered in young adults suffering from chronic recalcitrant panuveitis.

    Pediatric solid organ transplant recipients have a 100 to 200 times higher risk of non-Hodgkin lymphoma (NHL) than the general pediatric population. Consequently, transplant-related NHL may contribute considerably to the pediatric NHL burden in the United States. A cohort study using a linkage between the US transplant registry and 16 cancer registries was conducted. Cancer incidence rates were calculated for people less than 20 years old in the transplant and general populations. Rates were applied to transplant registry and US census data to estimate pediatric NHL counts for transplant recipients and the general population. During 1990-2012, an estimated 22,270 NHLs were diagnosed in US children and adolescents; they included 628 cases diagnosed in transplant recipients. Thus, 2.82% of pediatric NHL diagnoses in the general population (95% confidence interval [CI], 2.45%-3.19%) occurred in transplant recipients. Among transplant recipients, the most common subtypes were diffuse large B-cell lymphoma (DLBCL; 64.5% of cases) and Burkitt lymphoma (BL; 8.6%). For DLBCL and BL, transplant recipients contributed 7.62% (95% CI, 6.35%-8.88%) and 0.87% (95% CI, 0.51%-1.23%) of diagnoses, respectively. The proportion of NHLs that occurred in transplant recipients was highest among children less than 5 years old (4.46%; 95% CI, 3.24%-5.69%) and in more recent calendar years (3.73% in 2010-2012; 95% CI, 2.07%-5.39%). DLBCL patterns were similar, with transplant recipients contributing 19.78% of cases among children less than 5 years old (95% CI, 12.89%-26.66%) and 11.4% of cases in 2010-2012 (95% CI, 5.54%-17.28%). Among children and adolescents, solid organ transplant recipients contribute a substantial fraction of NHL diagnoses, particularly DLBCL diagnoses. This fraction has increased over time. Prevention efforts targeted toward this group could reduce the overall pediatric NHL burden. Cancer 2017. © 2017 American Cancer Society. © 2017 American Cancer Society.

    B cell non-Hodgkin lymphomas (B-NHLs) are the most common adult hematological cancers and many remain incurable. Development of chemotherapy regimens is confounded by the prevalence of B-NHL in older, frailer patients and the chemo-protective tumor microenvironment. Although biological therapies such as rituximab have significantly improved outcomes and selective kinase inhibitors are showing promise, the rate of new drug discovery remains disappointing, the treatments expensive and long-term benefits uncertain. An alternative strategy is redeployment of available, inexpensive and non-toxic drugs. Here, we demonstrate the antiproliferative and mitochondrial superoxide (MSO) driven pro-apoptotic activities of bezafibrate (BEZ) and medroxyprogesterone acetate (MPA) against B-NHL cells, with a bias toward MZL, in the presence and absence of the microenvironmental signal CD40L. Our study is the first to confirm the presence of CD40L within the lymph node of B-NHL and its capacity to drive B-NHL proliferation. These findings implicate BEZ + MPA as a potential therapeutic strategy in B-NHL.

    Full Text Available Non-Hodgkin lymphomas (NHLs are a heterogeneous group of hematologic malignancies which typically respond to standard first-line chemoimmunotherapy regimens. Unfortunately, patients with refractory NHL face a poor prognosis and represent an unmet need for improved therapeutics. We present two cases of refractory CD30+ NHL who responded to novel brentuximab vedotin- (BV- based regimens. The first is a patient with stage IV anaplastic large cell lymphoma (ALCL with cranial nerve involvement who failed front-line treatment with cyclophosphamide, doxorubicin, vincristine, etoposide, and prednisone (CHOEP and second line cyclophosphamide, vincristine, doxorubicin, dexamethasone alternating with high-dose methotrexate (MTX, and cytarabine (hyperCVAD with intrathecal- (IT- MTX and IT-cytarabine, but responded when BV was substituted for vincristine (hyperCBAD. The second patient was a man with stage IV diffuse large B-cell lymphoma (DLBCL with leptomeningeal involvement whose disease progressed during first-line rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP and progressed despite salvage therapy with rituximab, dexamethasone, cytarabine, and cisplatin (R-DHAP in whom addition of BV to topotecan resulted in a significant response. This report describes the first successful salvage treatments of highly aggressive, double refractory CD30+ NHL using two unreported BV-based chemoimmunotherapy regimens. Both regimens appear effective and have manageable toxicities. Further clinical trials assessing novel BV combinations are warranted.

  8. [Molecular abnormalities in lymphomas].

    2010-11-01

    Numerous molecular abnormalities have been described in lymphomas. They are of diagnostic and prognostic value and are taken into account for the WHO classification of these tumors. They also shed some light on the underlying molecular mechanisms involved in lymphomas. Overall, four types of molecular abnormalities are involved: mutations, translocations, amplifications and deletions of tumor suppressor genes. Several techniques are available to detect these molecular anomalies: conventional cytogenetic analysis, multicolor FISH, CGH array or gene expression profiling using DNA microarrays. In some lymphomas, genetic abnormalities are responsible for the expression of an abnormal protein (e.g. tyrosine-kinase, transcription factor) detectable by immunohistochemistry. In the present review, molecular abnormalities observed in the most frequent B, T or NK cell lymphomas are discussed. In the broad spectrum of diffuse large B-cell lymphomas microarray analysis shows mostly two subgroups of tumors, one with gene expression signature corresponding to germinal center B-cell-like (GCB: CD10+, BCL6 [B-Cell Lymphoma 6]+, centerine+, MUM1-) and a subgroup expressing an activated B-cell-like signature (ABC: CD10-, BCL6-, centerine-, MUM1+). Among other B-cell lymphomas with well characterized molecular abnormalies are follicular lymphoma (BCL2 deregulation), MALT lymphoma (Mucosa Associated Lymphoid Tissue) [API2-MALT1 (mucosa-associated-lymphoid-tissue-lymphoma-translocation-gene1) fusion protein or deregulation BCL10, MALT1, FOXP1. MALT1 transcription factors], mantle cell lymphoma (cycline D1 [CCND1] overexpression) and Burkitt lymphoma (c-Myc expression). Except for ALK (anaplastic lymphoma kinase)-positive anaplastic large cell lymphoma, well characterized molecular anomalies are rare in lymphomas developed from T or NK cells. Peripheral T cell lymphomas not otherwise specified are a heterogeneous group of tumors with frequent but not recurrent molecular abnormalities

    Abstract Sarcoidosis is a granulomatous disease that most frequently affects the lungs with pulmonary infiltrates and/or bilateral hilar and mediastinal lymphadenopathy. An association of sarcoidosis and lymphoproliferative disease has previously been reported as the sarcoidosis-lymphoma syndrome. Although this syndrome is characterized by sarcoidosis preceding lymphoma, very few cases of sarcoidosis following lymphoma have been reported. We describe the clinical, biological, and radiological characteristics and outcome of 39 patients presenting with sarcoidosis following lymphoproliferative disease, including 14 previously unreported cases and 25 additional patients, after performing a literature review. Hodgkin lymphoma and non-Hodgkin lymphoma were equally represented. The median delay between lymphoma and sarcoidosis was 18 months. Only 16 patients (41%) required treatment. Sarcoidosis was of mild intensity or self-healing in most cases, and overall clinical response to sarcoidosis was excellent with complete clinical response in 91% of patients. Sarcoidosis was identified after a follow-up computerized tomography scan (CT-scan) or 18fluorodeoxyglucose-positron emission tomography/computerized tomography (18FDG-PET/CT) evaluation in 18/34 patients (53%). Sarcoidosis is therefore a differential diagnosis to consider when lymphoma relapse is suspected on a CT-scan or 18FDG-PET/CT, emphasizing the necessity to rely on histological confirmation of lymphoma relapse.

    Full Text Available Background: Primary non-Hodgkin′s lymphoma (NHL of the gastrointestinal (GI tract is the most common extranodal lymphoma in pediatric age group. Yet, the overall incidence is very low. The rarity of the disease as well as variable clinical presentation prevents early detection when the possibility of cure exists. Materials and Methods: We studied six cases of primary GI NHL in pediatric age group with reference to their clinical presentation, anatomic distribution and histopathologic characteristics. Results: All were males except one. Intestinal obstruction was the presenting feature in 50%. Half the cases showed ileocaecal involvement, while large bowel was involved in 16%. Histology showed four cases of diffuse large B-cell lymphoma (DLBCL, one case of Burkitt lymphoma, and one Burkitt-like lymphoma. Immunohistochemistry for Tdt, CD20, CD3, CD30, bcl2, bcl6 confirmed the morphological diagnosis. Conclusion: Pediatric GI lymphoma commonly involves the ileocaecal region and presents with intestinal obstruction. A higher prevalence of DLBCL is found compared to other series. A high proliferative index is useful in differentiating Burkitt-like lymphoma from DLBCL.

    Full Text Available Background: Primary central nervous system lymphomas (PCNSL constitute a rare group of extranodal non-Hodgkin′s lymphomas (NHLs. Aim: To study the clinical and immunophenotypic profile of patients with a PCNSL who presented between the years 2000 and 2013 in a tertiary care center in South India. Materials and Methods: This was a retrospective study. Demographic and clinical data were obtained from the clinical case records. Inclusion criteria: Cases of PCNSL involving brain. Exclusion criteria: Cases of PCNSL involving the spinal cord, meninges and orbit as well as intravascular large B-cell lymphoma, lymphomas with evidence of systemic disease or secondary lymphomas. Archived slides and tissue blocks were retrieved. All cases had hematoxylin and eosin stained sections and immunohistochemistry for CD20, CD3, and MIB-1. Additional immunohistochemistry was performed for CD10, BCL6, and MUM1 on paraffin blocks with sufficient tissue. Results: There were a total of 73 cases with the mean age of presentation being 45.9 years (range 8-71 years and with a male predominance (male: female (M:F = 2.3:1. Headache was the commonest presenting complaint. The mean duration of symptoms was 10.6 weeks. All patients were immunocompetent. Most tumors were supratentorial in location. Out of 73 cases, 70 presented with a diffuse large B-cell lymphoma (DLBCL, two with a Burkitt′s lymphoma, and one with a lymphomatoid granulomatosis. Only 51 of the DLBCL cases had sufficient tissue for additional studies. Non-germinal center was the most common phenotype seen in 65.7% (33/51 of cases. Germinal center B-cell (GCB phenotype was seen in 18/51 cases (34.3%. Conclusion: DLBCL constituted the majority of PCNSLs and although non-germinal center was the predominant phenotype, more than a third of the cases were of the GCB phenotype. As the germinal center phenotype is known to have a better prognosis, further studies to explore its relevance in the Asian population are

    Objective: To evaluate clinical presentation, optimal diagnostic evaluation and treatment, and outcome in primary leptomeningeal lymphoma, a rare form of primary CNS lymphoma without parenchymal or systemic involvement. Methods: The International Primary CNS Lymphoma Collaborative Group, a multidisciplinary group of physicians with a particular interest in primary CNS lymphoma, retrospectively identified cases of lymphoma isolated to the leptomeninges as diagnosed by CSF cytology, flow cytometry, or biopsy, without systemic or parenchymal brain/spinal cord lymphoma or immunodeficiency. Results: Forty-eight patients were identified, with median age at diagnosis of 51 years and median Eastern Cooperative Oncology Group performance status of 2. Presenting symptoms were multifocal in 68%. Leptomeningeal enhancement was seen in 74% and CSF profile was abnormal in all cases. CSF cytology detected malignant lymphocytes in 67%. Flow cytometry identified monoclonal population in 80%, as did receptor gene rearrangement studies in 71%. Sixty-two percent had B-cell lymphoma, 19% T-cell, and 19% unclassified. Treatment varied and included fractionated radiotherapy (36%), systemic chemotherapy (78%), and intra-CSF chemotherapy (66%), with 66% receiving ≥2 modalities. Seventy-one percent had a favorable clinical response; ultimately, 44% received salvage treatment. Median overall survival was 24 months, with 11 patients still alive at 50 months follow-up. Conclusion: Primary leptomeningeal lymphoma is a rare form of primary CNS lymphoma. Patients usually present with multifocal symptoms, with evidence of leptomeningeal enhancement and diagnostic CSF analysis. Although treatment is highly variable, patients have a better prognosis than previously reported and a subset may be cured. PMID:24107866

    Purpose Previous studies have reported that survivors of non-Hodgkin lymphoma (NHL) have an increased risk of developing cutaneous melanoma; however, risks associated with specific treatments and immune-related risk factors have not been quantified. Patients and Methods We evaluated second melanoma risk among 44,870 1-year survivors of first primary NHL diagnosed at age 66 to 83 years from 1992 to 2009 and included in the Surveillance, Epidemiology, and End Results-Medicare database. Information on NHL treatments, autoimmune diseases, and infections was derived from Medicare claims. Results A total of 202 second melanoma cases occurred among survivors of NHL, including 91 after chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) and 111 after other NHL subtypes (cumulative incidence by age 85 years: CLL/SLL, 1.37%; other NHL subtypes, 0.78%). Melanoma risk after CLL/SLL was significantly increased among patients who received infused fludarabine-containing chemotherapy with or without rituximab (n = 18: hazard ratio [HR], 1.92; 95% CI, 1.09 to 3.40; n = 10: HR, 2.92; 95% CI, 1.42 to 6.01, respectively). Significantly elevated risks also were associated with T-cell activating autoimmune diseases diagnosed before CLL/SLL (n = 36: HR, 2.27; 95% CI, 1.34 to 3.84) or after CLL/SLL (n = 49: HR, 2.92; 95% CI, 1.66 to 5.12). In contrast, among patients with other NHL subtypes, melanoma risk was not associated with specific treatments or with T-cell/B-cell immune conditions. Generally, infections were not associated with melanoma risk, except for urinary tract infections (CLL/SLL), localized scleroderma, pneumonia, and gastrohepatic infections (other NHLs). Conclusion Our findings suggest immune perturbation may contribute to the development of melanoma after CLL/SLL. Increased vigilance is warranted among survivors of NHL to maximize opportunities for early detection of melanoma. PMID:26240221

    Hepatitis C virus (HCV) infection is associated with lymphoproliferative disorders and B-cell non-Hodgkin lymphomas (B-NHLs). Evaluation of the efficacy and safety profiles of different antiviral therapies in HCV patients with B-NHL is warranted. Methods: First, we evaluated the sustained virologic response (SVR) and safety of Peg-interferon-alpha (Peg-IFN) + ribavirin +/- first protease inhibitors (PI1s) therapy in 61 HCV patients with B-NHL enrolled in a nationwide observational survey compared with 94 matched HCV-infected controls without B-NHL. In a second series, interferon-free regimens using a newly optimal combination therapy with direct-acting antiviral drugs (DAAs) were evaluated in 10 patients with HCV and B-NHL. Results: The main lymphoma type was diffuse large B-cell lymphoma (38%) followed by marginal zone lymphoma (31%). In the multivariate analysis, patients with B-NHL treated by Peg-IFN-based therapy exhibited a greater SVR rate compared with controls, 50.8% vs 30.8%, respectively, p<0.01, odds ratio (OR) = 11.2 [2.3, 52.8]. B-NHL response was better (p = 0.02) in patients with SVR (69%) than in patients without SVR (31%). Premature discontinuation of Peg-IFN-based therapy was significantly more frequent in the B-NHL group (19.6%) compared with the control group (6.3%), p<0.02. Overall, survival was significantly enhanced in the controls than in the B-NHL group (hazard ratio = 34.4 [3.9, 304.2], p< 0.01). Using DAAs, SVR was achieved in 9/10 patients (90%). DAAs were both well tolerated and markedly efficient. Conclusions: The virologic response of HCV-associated B-NHL is high. Our study provides a comprehensive evaluation of different strategies for the antiviral treatment of B-NHL associated with HCV infection. PMID:27749916

    With a lifetime risk of 1% and 700 new cases per year, Non-Hodgkin lymphoma (NHL) is the seventh most frequent type of cancer in Denmark. The incidence of NHL has increased considerably in Western countries over the last decades; consequently, NHL is an increasing clinical problem. Ophthalmic lymphoma, (lymphoma localized in the ocular region, i.e. eyelid, conjunctiva, lacrimal sac, lacrimal gland, orbit, or intraocularly) is relatively uncommon, accounting for 5%-10% of all extranodal lymphomas. It is, however, the most common orbital malignancy. The purpose of this thesis was to review specimens from all Danish patients with a diagnosis of ophthalmic lymphoma during the period 1980-2005, in order to determine the distribution of lymphoma subtypes, and the incidence- and time trends in incidence for ophthalmic lymphoma. Furthermore, an extended analysis of the most frequent subtype, extranodal marginal zone lymphoma (MALT lymphoma), was done to analyse clinical factors and cytogenetic changes with influence on prognosis. A total of 228 Danish patients with a biopsy-reviewed verified diagnosis of ocular adnexal-, orbital-, or intraocular lymphoma were identified. We found that more than 50% of orbital- and ocular adnexal lymphomas were of the MALT lymphoma subtype, whereas diffuse large B-cell lymphoma (DLBCL) predominated intraocularly (Sjo et al. 2008a). Furthermore, lymphoma arising in the lacrimal sac was surprisingly predominantly DLBCL (Sjo et al. 2006). Incidence rates were highly dependent on patient age. There was an increase in incidence rates for the whole population from 1980 to 2005, corresponding to an annual average increase of 3.4% (Sjo et al. 2008a). MALT lymphoma arising in the ocular region was found in 116 patients (Sjo et al. 2008b). One third of patients had a relapse or progression of disease after initial therapy and relapses were frequently found at extra-ocular sites. Overall survival, however, was not significantly poorer for patients

    Full Text Available Introduction Extranodal non-Hodgkin lymphomas (NHLs are commonly described in patients with acquired immunodeficiency syndrome (AIDS and are related with an atypical morphology and aggressive clinical course. AIDS-associated lymphomas are characterized by their rapid progression, frequent extranodal manifestations, and poor outcome. Objective The aim of this article is to remake the clinical features of head and neck (HN NHL in patients with AIDS to facilitate early diagnosis and treatment. Methods We evaluated the epidemiologic, clinical, immunologic, virologic, and histopathologic characteristics of 24 patients with human immunodeficiency virus (HIV/AIDS with primary HN NHL treated at a single institution between 2002 and 2012. Histopathologic diagnosis was made according to the criteria of the World Health Organization Classification of Tumors of Hematopoietic and Lymphoid Tissues. Additional immunohistochemical stains were applied in all cases. Results Eighteen patients (75% were men and the median of age was 39 years. The gingiva and the hard palate were the most common sites of the lesions (15 patients, 62.5%. Lactate dehydrogenase levels were elevated in 16 cases (84%. Bone marrow infiltration was detected only in 4 cases (16.6%. The median CD4 T-cell count was 100 cells/µL. According to the histopathologic evaluation, the most common subtype was diffuse large B-cell lymphoma (12 cases, 50%, followed by plasmablastic lymphoma (9 cases, 37.5% and Burkitt lymphoma (3 cases, 12.5%. Conclusion HN NHL is a severe complication of advanced HIV/AIDS disease. Early diagnosis followed by chemotherapy plus highly active antiretroviral treatment is necessary to improve the prognosis and the survival of these patients.

    While the cellular origin of lymphoma is often characterized by chromosomal translocations and other genetic aberrations, its growth and development into a malignant neoplasm is highly dependent upon its ability to escape natural host defenses. Neoplastic cells interact with a variety of non-malignant cells in the tumor milieu to create an immunosuppressive microenvironment. The resulting functional impairment and dysregulation of tumor-associated immune cells not only allows for passive growth of the malignancy but may even provide active growth signals upon which the tumor subsequently becomes dependent. In the past decade, the success of immune checkpoint blockade and adoptive cell transfer for relapsed or refractory lymphomas has validated immunotherapy as a possible treatment cornerstone. Here, we review the mechanisms by which lymphomas have been found to evade and even reprogram the immune system, including alterations in surface molecules, recruitment of immunosuppressive subpopulations, and secretion of anti-inflammatory factors. A fundamental understanding of the immune evasion strategies utilized by lymphomas may lead to better prognostic markers and guide the development of targeted interventions that are both safer and more effective than current standards of care.

    The centrofacial angiocentric lymphoma is a rare lymphoid neoplasm, with an often-difficult diagnosis due to the non-specific clinical picture. On many occasions it is necessary to perform various biopsies to reach the correct diagnosis. This lymphoma is an aggressive Non-Hodgkin's (NHL) type, which is normally found in the upper respiratory tract (predominantly in the nasal cavity), and has an ominous prognosis, as the average survival rate is between 12 and 18 months (1). It is predominantly found in subjects of oriental and South American extraction, who are between the ages of 50 and 60 years and with a slight tendency towards males (2:1). This is the case study of a female Ecuadorian patient who was referred to our department with a hemifacial edema, chocolate- like rhinorrhea and nasal respiratory obstruction, which had been treated with antibiotics and anti-inflammatories for a month without success. After performing a number of diagnostic tests, it was found histologically that the patient had an extranodal T-cell lymphoma of the nasal type (also known as T-cell angiocentric lymphoma).

    Development of lymphoproliferative diseases during the course of autoimmune and chronic inflammatory conditions is well established. Conversely, development of clinical or biological signs of autoimmunity at the time of the diagnosis of lymphoma or during its course indicates that lymphoma and autoimmune manifestations may constitute two faces of the same process. The aim of this review is to describe autoimmune manifestations related to non-Hodgkin's lymphoma and Hodgkin's lymphoma, their specificity according to the lymphoma subtype and their physiopathological signification. Lymphoma-related autoimmune manifestations include mainly skin diseases, hematological manifestations, rheumatic diseases and renal lesions. Despite the lack of studies providing a systematic prospective assessment, autoimmune manifestations are observed in all lymphoma subtypes and seem particularly prevalent in marginal-zone lymphoma and T-cell lymphoma. Autoimmune manifestation's physiopathology may implicate production of autoantibodies by CD5-positive autoreactive B cells, a loss of immune tolerance, an alteration of the Fas/Fas-ligand pathway and/or a chronic antigenic stimulation. Monoclonal antibodies (including rituximab, Campath-1H or epratuzumab) constitute the most promising approach to treat lymphoma-related immune disorders.

    Lymphoma is the most common hematologic malignancy and represents approximately 5.3% of all cancers. The World Health Organization published a revised classification scheme in 2008 that groups lymphomas by cell type and molecular, cytogenetic, and phenotypic characteristics. Most lymphomas affect the thorax at some stage during the course of the disease. Affected structures within the chest may include the lungs, mediastinum, pleura, and chest wall, and lymphomas may originate from these sites as primary malignancies or secondarily involve these structures after arising from other intrathoracic or extrathoracic sources. Pulmonary lymphomas are classified into one of four types: primary pulmonary lymphoma, secondary pulmonary lymphoma, acquired immunodeficiency syndrome-related lymphoma, and post-transplantation lymphoproliferative disorders. Although pulmonary lymphomas may produce a myriad of diverse findings within the lungs, specific individual features or combinations of features can be used, in combination with secondary manifestations of the disease such as involvement of the mediastinum, pleura, and chest wall, to narrow the differential diagnosis. While findings of thoracic lymphoma may be evident on chest radiography, computed tomography has traditionally been the imaging modality used to evaluate the disease and effectively demonstrates the extent of intrathoracic involvement and the presence and extent of extrathoracic spread. However, additional modalities such as magnetic resonance imaging of the thorax and {sup 18}F-FDG PET/CT have emerged in recent years and are complementary to CT in the evaluation of patients with lymphoma. Thoracic MRI is useful in assessing vascular, cardiac, and chest wall involvement, and PET/CT is more accurate in the overall staging of lymphoma than CT and can be used to evaluate treatment response.

    Lymphoma consists of a variety of malignancies of lymphocyte origin. A spectrum of clinical peripheral neuropathy syndromes with different disease mechanisms occurs in about 5% of lymphoma patients. There exists a complex inter-relationship between lymphoproliferative malignancies and autoimmunity. An imbalance in the regulation of the immune system presumably underlies various immune-mediated neuropathies in patients with lymphoma. This article reviews lymphoma and more-or-less well-defined dysimmune neuropathy subgroups that are caused by humoral and/or cell-mediated immune disease mechanisms directed against known or undetermined peripheral nerve antigens.

    Full Text Available Despite its well-known histological and clinical features, Hodgkin's lymphoma (HL has recently been the object of intense research activity, leading to a better understanding of its phenotype, molecular characteristics, histogenesis, and possible mechanisms of lymphomagenesis. There is complete consensus on the B-cell derivation of the tumor in most cases, and on the relevance of Epstein-Barr virus infection and defective cytokinesis in at least a proportion of patients. The REAL/WHO classification recognizes a basic distinction between lymphocyte predominance HL (LP-HL and classic HL (cHL, reflecting the differences in clinical presentation and behavior, morphology, phenotype, and molecular features. cHL has been classified into four subtypes: lymphocyte rich, nodular sclerosing, with mixed cellularity, and lymphocyte depleted. The borders between cHL and anaplastic large-cell lymphoma have become sharper, whereas those between LP-HL and T-cell-rich B-cell lymphoma remain ill defined. Treatments adjusted to the pathobiological characteristics of the tumor in at-risk patients have been proposed and are on the way to being applied.

    2016-12-01

    Intravascular lymphoma is a rare malignancy which is characterized by a proliferation of atypical appearing B cells, generally confined to vascular lumina. A tissue biopsy demonstrating the pathology is required to make a diagnosis. The tumor is often disseminated at the time of diagnosis and prognosis is poor, even with aggressive chemotherapy. Neurologic presentations of this neoplasm can be quite varied. This report documents the presence of intravascular lymphoma diagnosed on a brain biopsy in a 60-year-old man. He initially presented 6months before brain biopsy with chest pain and hypotension, warranting coronary artery bypass graft surgery. Four months later, he presented with signs attributed to a stroke (diaphoresis, slumped over in a chair and left hand weakness). He subsequently developed a sudden onset wide-based gait, left leg numbness, word finding difficulties and worsening confusion. A MRI study showed multiple infarcts in the brain, including cerebellum. Invasive angiogram suggested vasculitis. He was started on a course of treatment for presumed central nervous system vasculitis. He continued to develop signs suggestive of ongoing infarct development and a biopsy from the right parietal was taken. The biopsy showed atypical intravascular CD20 positive staining B cells, consistent with intravascular lymphoma. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2009-01-01

    Full Text Available Abstract Background Non-Hodgkin's lymphomas (NHLs have been linked to proximity to industrial areas, but evidence regarding the health risk posed by residence near pollutant industries is very limited. The European Pollutant Emission Register (EPER is a public register that furnishes valuable information on industries that release pollutants to air and water, along with their geographical location. This study sought to explore the relationship between NHL mortality in small areas in Spain and environmental exposure to pollutant emissions from EPER-registered industries, using three Poisson-regression-based mathematical models. Methods Observed cases were drawn from mortality registries in Spain for the period 1994–2003. Industries were grouped into the following sectors: energy; metal; mineral; organic chemicals; waste; paper; food; and use of solvents. Populations having an industry within a radius of 1, 1.5, or 2 kilometres from the municipal centroid were deemed to be exposed. Municipalities outside those radii were considered as reference populations. The relative risks (RRs associated with proximity to pollutant industries were estimated using the following methods: Poisson Regression; mixed Poisson model with random provincial effect; and spatial autoregressive modelling (BYM model. Results Only proximity of paper industries to population centres (>2 km could be associated with a greater risk of NHL mortality (mixed model: RR:1.24, 95% CI:1.09–1.42; BYM model: RR:1.21, 95% CI:1.01–1.45; Poisson model: RR:1.16, 95% CI:1.06–1.27. Spatial models yielded higher estimates. Conclusion The reported association between exposure to air pollution from the paper, pulp and board industry and NHL mortality is independent of the model used. Inclusion of spatial random effects terms in the risk estimate improves the study of associations between environmental exposures and mortality. The EPER could be of great utility when studying the effects of

    2014-01-01

    Full Text Available Background. Lymphoma of the urinary bladder (LUB is rare. Aims. To review the literature on LUB. Methods. Various internet databases were used. Results. LUB can be either primary or secondary. The tumour has female predominance; most cases occur in middle-age women. Secondary LUB occurs in 10% to 25% of leukemias/lymphomas and in advanced-stage systemic lymphoma. Less than 100 cases have been reported. MALT typically affects adults older than 60 years; 75% are female. Diffuse large B-cell lymphoma is also common and may arise from transformation of MALT. LUB presents with haematuria, dysuria, urinary frequency, nocturia, and abdominal or back pain. Macroscopic examination of LUBs show large discrete tumours centred in the dome or lateral walls of the bladder. Positive staining of LUB varies by the subtype of lymphoma; B-cell lymphomas are CD20 positive. MALT lymphoma is positively stained for CD20, CD19, and FMC7 and negatively stained for CD5, CD10, and CD11c. LUB stains negatively with Pan-keratin, vimentin, CK20, and CK7. MALT lymphoma exhibits t(11; 18(q21: 21. Radiotherapy is an effective treatment for the MALT type of LUB with no recurrence. Conclusions. LUB is diagnosed by its characteristic morphology and immunohistochemical characteristics. Radiotherapy is a useful treatment.

    Rapid regression of all symptoms was obtained after moderate chemotherapy in two women aged 69 and 77 years respectively with malignant non-Hodgkin's lymphomas. Cervico-facial locations of these tumors are discussed in relation to definition, etiology, geographic factors, genetic markers, and associated immunologic disorders. Diagnosis requires a series of explorations including, obviously as a last resort, exploratory cervicotomy. Other regions may be involved and must be investigated, but lesions not affecting lymph nodes occur in only approximately 2 p. cent of patients with cervico-facial malignant non-Hodgkin's lymphoma (approximately 10 p. cent of all malignant non-Hodgkin's lymphomas). Other localizations include the hard palate, gums, sinuses, and salivary glands. Burkitt's lymphoma represents, on the contrary, 30 p. cent of malignant non-Hodgkin's lymphoma seen in European children. The different therapeutic modalities available are discussed.

    Full Text Available Data supporting the role of radiotherapy in secondary trigeminal nerve lymphoma is scarce. Here, I report the case of 64-year-old Thai male diagnosed as gastric diffuse large B cell lymphoma with secondary trigeminal nerve lymphoma. He had previously received one cycle of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP, followed by five cycles of rituximab plus CHOP (R-CHOP with intrathecal methotrexate (MTX and cytarabine (Ara-C. One month after the last cycle of R-CHOP, he developed a headache and numbness on the left side of his face. MRI revealed thickening of the left trigeminal nerve. He received one intrathecal injection of MTX and Ara-C, followed by systemic chemotherapy. After receiving intrathecal chemotherapy, his symptoms disappeared. Clinical response and MRI studies suggested secondary trigeminal nerve lymphoma. Two months later, our patient’s secondary trigeminal nerve lymphoma had progressed. Salvage whole brain irradiation (36 Gy with boost dose (50 Gy along the left trigeminal nerve was given. Unfortunately, our patient developed heart failure and expired during the radiotherapy session. In conclusion and specific to secondary central nervous system lymphoma (SCNSL, radiotherapy may benefit patients who fail to respond to systemic chemotherapy and palliative treatment. The results this report fail to support the role of radiotherapy in secondary trigeminal nerve lymphoma.

    The 2016 revision of the World Health Organization (WHO) classification for lymphoma has included a new category of lymphoma, separate from diffuse large B-cell lymphoma, termed high-grade B-cell lymphoma with translocations involving myc and bcl-2 or bcl-6. These lymphomas, which occur in <10% of cases of diffuse large B-cell lymphoma, have been referred to as double-hit lymphomas (or triple-hit lymphomas if all 3 rearrangements are present). It is important to differentiate these lymphomas from the larger group of double-expressor lymphomas, which have increased expression of MYC and BCL-2 and/or BCL-6 by immunohistochemistry, by using variable cutoff percentages to define positivity. Patients with double-hit lymphomas have a poor prognosis when treated with standard chemoimmunotherapy and have increased risk of central nervous system involvement and progression. Double-hit lymphomas may arise as a consequence of the transformation of the underlying indolent lymphoma. There are no published prospective trials in double-hit lymphoma, however retrospective studies strongly suggest that aggressive induction regimens may confer a superior outcome. In this article, I review my approach to the evaluation and treatment of double-hit lymphoma, with an eye toward future clinical trials incorporating rational targeted agents into the therapeutic armamentarium. © 2017 by The American Society of Hematology.

  9. Lymphoma caused by intestinal microbiota.

    Yamamoto, Mitsuko L; Schiestl, Robert H

    2014-09-01

    The intestinal microbiota and gut immune system must constantly communicate to maintain a balance between tolerance and activation: on the one hand, our immune system should protect us from pathogenic microbes and on the other hand, most of the millions of microbes in and on our body are innocuous symbionts and some can even be beneficial. Since there is such a close interaction between the immune system and the intestinal microbiota, it is not surprising that some lymphomas such as mucosal-associated lymphoid tissue (MALT) lymphoma have been shown to be caused by the presence of certain bacteria. Animal models played an important role in establishing causation and mechanism of bacteria-induced MALT lymphoma. In this review we discuss different ways that animal models have been applied to establish a link between the gut microbiota and lymphoma and how animal models have helped to elucidate mechanisms of microbiota-induced lymphoma. While there are not a plethora of studies demonstrating a connection between microbiota and lymphoma development, we believe that animal models are a system which can be exploited in the future to enhance our understanding of causation and improve prognosis and treatment of lymphoma.

    Full Text Available Hodgkin’s lymphoma is a lymphoid tumour that represents about 1% of all de novo neoplasms occurring every year worldwide. Its diagnosis is based on the identification of characteristic neoplastic cells within an inflammatory milieu. Molecular studies have shown that most, if not all cases, belong to the same clonal population, which is derived from peripheral B-cells. The relevance of Epstein-Barr virus infection at least in a proportion of patients was also demonstrated. The REAL/WHO classification recognizes a basic distinction between nodular lymphocyte predominance  HL (NLPHL and classic HL (CHL, reflecting the differences in clinical presentation, behavior, morphology, phenotype, molecular features as well as in the composition of their cellular background. CHL has been classified into four subtypes: lymphocyte rich, nodular sclerosing, mixed cellularity and lymphocyte depleted. Despite its well known histological and clinical features, Hodgkin's lymphoma (HL has recently been the object of intense research activity, leading to a better understanding of its phenotype, molecular characteristics and possible mechanisms of lymphomagenesis.

    Full Text Available Background: The prevalence of coeliac disease is around 1% in general population but this is often unrecognised. The classical presentation of adult coeliac disease is characterized by diarrhoea and malabsorption syndrome, but atypical presentations are probably more common and are characterized by iron deficiency anaemia, weight loss, fatigue, infertility, arthralgia, peripheral neuropathy and osteoporosis. Unusual are the coagulation disorders (prevalence 20% and these are due to vitamin K malabsorption (prolonged prothrombin time. Clinical case: A 64-year-old man was admitted to our Department for an extensive spontaneous haematoma of the right leg. He had a history of a small bowel resection for T-cell lymphoma, with a negative follow-up and he didn’t report any personal or familiar history of bleeding. Laboratory tests showed markedly prolonged prothrombin (PT and partial-thromboplastin time (PTT, corrected by mixing studies, and whereas platelet count and liver tests was normal. A single dose (10 mg of intravenous vitamin K normalized the PT. Several days before the patient had been exposed to a superwarfarin pesticide, but diagnostic tests for brodifacoum, bromadiolone or difenacoum were negative. Diagnosis of multiple vitamin K-dependent coagulationfactor deficiencies (II, VII, IX, X due to intestinal malabsorption was made and coeliac disease was detected. Therefore the previous lymphoma diagnosis might be closely related to coeliac disease. Conclusions: A gluten free diet improves quality of life and restores normal nutritional and biochemical status and protects against these complications.

    2010-01-01

    Indolent Non Hodgkin's lymphoma (NHL) comprises a group of incurable, generally slow growing lymphomas highly responsive to initial therapy with a relapsing and progressive course. Rituximab, an anti CD-20 antibody, has had a large impact on treatment of indolent NHL. Its effectiveness as a single agent and in conjunction with known chemotherapy regimens has made it a standard of care in the treatment of NHL. Analysis of data obtained from NHL clinical trials as well as data from the National Cancer Institute indicates that the overall survival of indolent NHL has improved since the discovery of rituximab. Given its effectiveness and tolerability, it is currently being investigated as a maintenance agent with encouraging results. This review summarizes several landmark trials utilizing rituximab as a single agent and in combination with chemotherapy for treatment of NHL. In addition, a review of the studied rituximab maintenance dosing schedules and its impact on NHL will also be presented. Overall, rituximab has changed the landscape for treatment of indolent NHL however additional research is necessary to identify the optimal dosing schedule as well as patients most likely to respond to prolonged rituximab therapy.

    The CD20 marker continues to be exploited as a therapeutic target for non-Hodgkin's lymphoma. Obinutuzumab is part of a new generation of anti-CD20 monoclonal antibodies, which are synthesized using molecular engineering technology, resulting in novel target epitopes and unprecedented optimization of antibody-dependent cellular cytotoxicity and antibody-dependent cellular phagocytosis. Rituximab is the current gold standard for anti-CD20 therapy, yet despite outstanding results published over the past decade, many patients continue to relapse after anti-CD20 regimens. Obinutuzumab is slowly positioning itself in the treatment of CD20+ B-cell neoplasms. On the basis of favorable results from the phase III GADOLIN trial, obinutuzumab was recently approved by the U.S. Food and Drug Administration in combination with bendamustine followed by obinutuzumab maintenance, for the treatment of follicular lymphoma (FL) patients who relapsed or are refractory to a rituximab-containing regimen. Additional phase III trials are underway to test obinutuzumab as a first-line anti-CD20 agent in FL with good preliminary results (GALLIUM trial); thus, it is likely that obinutuzumab will soon achieve a first-line indication. It is plausible that obinutuzumab will replace rituximab as the gold standard for chemoimmunotherapy in FL, although some safety concerns still need to be resolved. This review will address the preclinical pharmacology and the main aspects of the clinical development of obinutuzumab for the treatment of FL.

    2015-11-01

    Hodgkin lymphoma is a rare B-cell malignant neoplasm affecting approximately 9000 new patients annually. This disease represents approximately 11% of all lymphomas seen in the United States and comprises 2 discrete disease entities--classical Hodgkin lymphoma and nodular lymphocyte-predominant Hodgkin lymphoma. Within the subcategorization of classical Hodgkin lymphoma are defined subgroups: nodular sclerosis, mixed cellularity, lymphocyte depletion, and lymphocyte-rich Hodgkin lymphoma. Staging of this disease is essential for the choice of optimal therapy. Prognostic models to identify patients at high or low risk for recurrence have been developed, and these models, along with positron emission tomography, are used to provide optimal therapy. The initial treatment for patients with Hodgkin lymphoma is based on the histologic characteristics of the disease, the stage at presentation, and the presence or absence of prognostic factors associated with poor outcome. Patients with early-stage Hodgkin lymphoma commonly receive combined-modality therapies that include abbreviated courses of chemotherapy followed by involved-field radiation treatment. In contrast, patients with advanced-stage Hodgkin lymphoma commonly receive a more prolonged course of combination chemotherapy, with radiation therapy used only in selected cases. For patients with relapse or refractory disease, salvage chemotherapy followed by high-dose treatment and an autologous stem cell transplant is the standard of care. For patients who are ineligible for this therapy or those in whom high-dose therapy and autologous stem cell transplant have failed, treatment with brentuximab vedotin is a standard approach. Additional options include palliative chemotherapy, immune checkpoint inhibitors, nonmyeloablative allogeneic stem cell transplant, or participation in a clinical trial testing novel agents.

    Full Text Available Indolent B-cell lymphomas account for approximately 40% of all non-Hodgkin lymphomas (NHLs. Advances in technology have contributed to improvements in the diagnosis and classification of indolent non-Hodgkin lymphomas. Follicular Lymphomas are the most common although the frequency varies significantly throughout the world. The description of the Follicular Lymphoma International Prognostic Index (FLIPI was an important step in identifying patient subgroups, but its use in the clinical practice has not been established yet. The use of a larger number of paraffin active monoclonal antibodies for immunohistochemistry, molecular cytogenetic studies including standard cytogenetics, multi-color fluorescence in-situ hybridization (FISH, polymerase chain reaction and locus-specific fluorescence insitu hybridization as well as developments in high-resolution techniquesincluding microarray gene expression profiling allow more accurate diagnosis andprecise definition of biomarkers of value in risk stratification. The identification ofdiseasespecific gene lists resulting from expression profiling provides a number ofpotential protein targets that can be validated using immunohistochemistry. Analysesof gene expression profiles or constitutive gene variations may also provide additional insight for prognostication in the near future. A comprehensive understanding of the biology of these distinct lymphoid tumors will allow us to identify novel diseaserelated genes and should facilitate the development of improved diagnosis, outcome prediction, and personalized approaches to treatment.Os linfomas de células B indolentes representam aproximadamente 40% do total de linfomas não Hodgkin (LNHs.

    Hodgkin lymphoma has gone from an incurable disease to one for which the majority of patients will be cured. Combined chemotherapy and radiotherapy achieves the best disease control rates and results in many long-term survivors. As a result, a majority of long-term Hodgkin lymphoma survivors live to experience severe late treatment-related complications, especially cardiovascular disease and second malignancies. The focus of research and treatment for Hodgkin lymphoma is to maintain the current high rates of disease control while reducing treatment-related morbidity and mortality. Efforts to reduce late treatment complications focus on improvements in both systemic therapies and radiotherapy. Herein we review the basis for the benefits of proton therapy over conventional X-ray therapy. We review outcomes of Hodgkin lymphoma treated with proton therapy, and discuss the ability of protons to reduce radiation dose to organs at risk and the impact on the most significant late complications related to the treatment.

    Approximately 10% of patients with malignant lymphoma will show neurological symptoms at some time during the course of their illness. In non-Hodgkin lymphoma, CNS involvement is more frequent than in Hodgkin's disease. Diffuse histiocytic and poorly differentiated lymphomas, bone marrow involvement, advanced tumor stage and hematogenous spread are particular risk factors. Invasion of the spinal canal is the most common type of CNS involvement. Intracranial lesions, which are comparatively rare, may present as intracerebral metastases, epi- or subdural masses or focal or diffuse leptomeningeal disease. Lymphomatous leptomeningitis usually cannot be demonstrated by CT. On the other hand, dural and cerebral parenchymal lesions are sometimes highly characteristic of lymphoma as a result of their features and location.

    Full Text Available Primary lymphoma of the colon is a rare tumor of the gastrointestinal (GI tract and comprises only 0.2-1.2% of all colonic malignancies. The most common variety of colonic lymphoma is non-Hodgkin′s lymphoma (NHL. The GI tract is the most frequently involved site, accounting for 30-40% of all extra nodal lymphomas, approximately 4-20% of which are NHL. The stomach is the most common location of GI lymphomas, followed by the small intestine. Early diagnosis may prevent intestinal perforation; however, the diagnosis is often delayed in most cases. Therapeutic approaches described in two subsets include: Radical tumor resection (hemicolectomy plus multi-agent chemotherapy (polychemotherapy in early stage patients, biopsy plus multidrug chemotherapy in advanced stage patients. Radiotherapy is reserved for specific cases; surgery alone can be considered as an adequate treatment for patients with low-grade NHL disease that does not infiltrate beyond the sub mucosa. Although resection plays an important role in the local control of the disease and in preventing bleeding and/or perforation, it rarely eradicates the lymphoma by itself. Those with limited stage disease may enjoy prolonged survival when treated with aggressive chemotherapy.

  6. Molecular Pathogenesis of MALT Lymphoma

    Directory of Open Access Journals (Sweden)

    Katharina Troppan

    2015-01-01

    Full Text Available Approximately 8% of all non-Hodgkin lymphomas are extranodal marginal zone B cell lymphoma of mucosa associated lymphoid tissue (MALT, also known as MALT lymphoma, which was first described in 1983 by Isaacson and Wright. MALT lymphomas arise at a wide range of different extranodal sites, with the highest frequency in the stomach, followed by lung, ocular adnexa, and thyroid, and with a low percentage in the small intestine. Interestingly, at least 3 different, apparently site-specific, chromosomal translocations and missense and frameshift mutations, all pathway-related genes affecting the NF-κB signal, have been implicated in the development and progression of MALT lymphoma. However, these genetic abnormalities alone are not sufficient for malignant transformation. There is now increasing evidence suggesting that the oncogenic product of translocation cooperates with immunological stimulation in oncogenesis, that is, the association with chronic bacterial infection or autoaggressive process. This review mainly discusses MALT lymphomas in terms of their genetic aberration and association with chronic infections and summarizes recent advances in their molecular pathogenesis.

  7. The rGel/BLyS Fusion Toxin Inhibits Diffuse Large B-cell Lymphoma Growth In Vitro and In Vivo

    Directory of Open Access Journals (Sweden)

    2010-05-01

    Full Text Available Diffuse large B-cell lymphoma (DLBCL is an aggressive subtype of B-cell non-Hodgkin lymphoma (NHL and accounts for 30%to 40%of NHL. Molecules targeting nuclear factor-κB (NF-κB are expected to be of therapeutic value in those tumors where NF-κB seems to play a unique survival role such as activated B-cell (ABC-subtype DLBCL. We previously generated a rGel/BLyS fusion toxin for receptor-mediated delivery of the rGel toxin specifically to malignant B cells. In this study, we examined this fusion toxin for its ability to suppress DLBCL growth in vitro and in vivo. rGel/BLyS was specifically cytotoxic to DLBCL lines expressing all three BLyS receptors and constitutively active NF-κB. Treatment with rGel/BLyS induced down-regulation of the phosphorylation of inhibitory subunit of NF-κB (IκB-α, inhibition of NF-κB DNA-binding activity, and accumulation of IκB-α. In agreement with these results, we additionally found that rGel/BLyS downregulated levels of several NF-κB targets including Bcl-xL, Mcl-1, survivin, and x-chromosome linked inhibitor-of-apoptosis. Treatment also induced up-regulation of Bax and apoptosis through caspase-3 activation and poly ADP-ribose polymerase cleavage. Importantly, rGel/BLyS significantly inhibited tumor growth (P < .05 in a DLBCL xenograft model. Thus, our results indicate that rGel/BLyS is an excellent candidate for the treatment of aggressive NHLs that are both dependent on NF-κB and are resistant to conventional chemotherapeutic regimens.

  8. Peripheral blood complete remission after splenic irradiation in Mantle-Cell Lymphoma with 11q22-23 deletion and ATM inactivation

    Full Text Available Abstract Mantle Cell Lymphoma (MCL is a well-known histological and clinical subtype of B-cell non-Hodgkin's Lymphomas. It is usually characterized by an aggressive disease course, presenting with advanced stage disease at diagnosis and with low response rates to therapy. However few cases of indolent course MCL have been described. We herein report a case of MCL with splenomegaly and peripheral blood involvement as main clinical features. The patient underwent moderate dose splenic radiation therapy and achieved spleen downsizing and peripheral blood complete remission. Splenic irradiation has been extensively used in the past as palliative treatment in several lymphoproliferative disorders and a systemic effect and sometimes peripheral blood complete remissions have been observed. Mainly advocated mechanisms responsible for this phenomenon are considered direct radiation-induced apoptotic cell death, immune modulation via proportional changes of lymphocyte subsets due to known differences in intrinsic radiosensitivity and a radiation-induced cytokine release. The peculiar intrinsic radiosensitivity pattern of lymphoid cells could probably be explained by well-defined individual genetic and molecular features. In this context, among NHLs, MCL subtype has the highest rate of ATM (Ataxia Teleangiectasia Mutated inactivation. While the ATM gene is thought to play a key-role in detecting radiation-induced DNA damage (expecially Double Strand Breaks, recent in vitro data support the hypothesis that ATM loss may actually contribute to the radiosensitivity of MCL cells. ATM status was retrospectively investigated in our patient, with the tool of Fluorescence In Situ Hybridization, showing a complete inactivation of a single ATM allele secondary to the deletion of chromosomal region 11q22-23. The presence of this kind of cytogenetic aberration may be regarded in the future as a potential predictive marker of radiation response.

    Full Text Available Abstract Background An elevated CD4/CD8 T-cell ratio on flow cytometry (FCM analysis has been reported in the literature to be associated with Hodgkin lymphoma (HL. The purpose of our study was to determine the diagnostic significance of an elevated CD4/CD8 ratio in lymph node fine needle aspiration (FNA specimens. Design Between 1996 and 2002, out of 837 lymph node FNAs submitted for flow cytometry analysis, 85 cases showed an elevated CD4/CD8 ratio, defined as greater than or equal to 4, without definitive evidence of a lymphoproliferative disorder. The cytologic diagnoses of these 85 cases were grouped into four categories: reactive, atypical, Hodgkin lymphoma (HL, and non-Hodgkin lymphoma (NHL. Histologic follow-up was available in 17/85 (20% of the cases. Results 5 of the 64 cases in which FCM and cytology did not reveal evidence of a lymphoproliferative disease had tissue follow-up because of persistent lymphadenopathy and high clinical suspicion. 3/5 (60% confirmed the diagnosis of reactive lymphadenopathy. The two remaining cases (40% were positive for lymphoma (1HL, 1NHL. 8/15 cases called atypical on cytology had histologic follow-up. 7/8 (87.5% cases were positive for lymphoma (3HL, 4NHL. 3/4 cases called HL on cytology had tissue follow-up and all 3 (100% confirmed the diagnosis of HL. One case diagnosed as NHL on cytology was found to be a diffuse large B-cell lymphoma. In summary, out of 17 cases with histologic follow-up 4/17 (24% were reactive with CD4/CD8 T-cell ratio of 4.1–29, 7/17 (41% were HLs with CD4/CD8 T-cell ratio of 5.3 – 11, and 6/17 (35% were NHLs with CD4/CD8 T-cell ratio of 4.2 – 14. Conclusion An elevated CD4/CD8 ratio on FCM is a nonspecific finding which may be seen in both reactive and lymphoproliferative disorders. The cytomorphologic features of the smear are more relevant than the sole flow cytometric finding of an elevated CD4/CD8 ratio.

    Hodgkin lymphoma (HL) accounts for approximately 0.6% of all new cancer cases, 10% of all lymphomas in the USA, leading to an approximate 9000 new cases per year. It is very unique in that the neoplastic Hodgkin and Reed-Sternberg (HRS) cells of classical HL account for only 1% of the tumor tissue in most cases, with various inflammatory cells including B-cells, T-cells, mast cells, macrophages, eosinophils, neutrophils, and plasma cells comprising the tumor microenvironment. Recent research has identified germinal center B-cells to be the cellular origin of HRS cells. Various transcription factor dysregulation in these neoplastic cells that explains for the loss of B-cell phenotype as well as acquisition of survival and anti-apoptotic features of HRS cells has been identified. Aberrant activation of nuclear factor-kappa B (NF-κB), Janus kinase (JAK)/signal transducer and activator of transcription (STAT), and phosphoinositide 3-kinase (PI3K) pathways play a central role in HL pathogenesis. Both intrinsic genetic mechanisms as well as extrinsic signals have been identified to account for the constitutive activation of these pathways. The extrinsic factors that regulate the activation of transcription pathways in HRS cells have also been studied in detail. Cytokines and chemokines produced both by the HRS cells as well as cells of the microenvironment of HL work in an autocrine and/or paracrine manner to promote survival of HRS cells as well as providing mechanisms for immune escape from the body's antitumor immunity. The understanding of various mechanisms involved in the lymphomagenesis of HL including the importance of its microenvironment has gained much interest in the use of these microenvironmental features as prognostic markers as well as potential treatment targets. In this article, we will review the pathogenesis of HL starting with the cellular origin of neoplastic cells and the mechanisms supporting its pathogenesis, especially focusing on the

    Lymphomas are classified as either Hodgkin's or non-Hodgkin's. The 2 subtypes of non-Hodgkin's lymphoma that can present primarily in the skin are cutaneous T-cell lymphoma and cutaneous B-cell lymphoma, both of which tend to be low-grade malignant neoplasms. Recently another distinct subtype of lymphoma was discovered, the natural killer (NK)/T-cell lymphoma, which can involve the skin in a primary or secondary fashion. The NK/T-cell subtype of lymphoma is characterized by the expression of the NK-cell antigen CD56. These CD56(+) lymphomas are further subdivided into nasal NK/T-cell lymphomas that commonly present as midfacial destructive disease and non-nasal NK/T-cell lymphomas that often arise in extranodal locations, including the skin. We report a case of aggressive NK-cell leukemia/lymphoma with numerous secondary cutaneous lesions and review the clinical and histopathologic spectrum of non-nasal CD56(+) lymphomas, with an emphasis on the dermatologic findings.

    Approximately 90% of patients with limited-stage Hodgkin lymphoma are cured. The cure rate in advanced-stage Hodgkin lymphoma is dramatically better than it once was, but it is still lower than the rate in patients with limited disease. The choice of treatment is based on several factors, including symptoms, disease stage, extent of tumor burden, and prognosis. Positron emission tomography scanning can be used to assess the patient's stage of disease, which can allow further individualization of therapy. Traditional frontline treatment options include doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) and, for high-risk patients, bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP). Autologous stem cell transplantation cures approximately 50% of patients. The antibody-drug conjugate brentuximab vedotin is very active in relapsed/refractory Hodgkin lymphoma. Data presented at the 2014 meeting of the American Society of Hematology (ASH) showed that brentuximab vedotin was beneficial in several settings, including as consolidation therapy posttransplant in patients at high risk for relapse, as first-line salvage therapy in relapsed/refractory Hodgkin lymphoma prior to autologous hematopoietic cell transplantation, and in combination with bendamustine in relapsed/refractory disease. The ASH meeting also offered promising data on novel agents, such as the programmed cell death 1 (PD-1) inhibitors. In this monograph, 4 experts in the management of Hodgkin lymphoma discuss various aspects of the disease and provide their perspectives on the new data presented at the ASH meeting.

    Full Text Available Malignant tumors of the thyroid gland account for about 1% of thenewly diagnosed malignant tumors each year, and their incidence inwomen is twice the incidence in men. According to the WHO classification (2004 thyroid tumors are divided into: carcinoma of the thyroid, adenoma and similar tumors, and other thyroid tumors which include: teratomas, angiosarcomas, paragangliomas and others, as well as primary lymphomas and plasmacytomas. Primary thyroid lymphomasare defined as lymphomas which originate in the thyroid gland. This study presents the case of a 68-year-old patient with a thyroid lymphoma, which caused compression of the airways. In the patientpresented there was reduced activity of the thyroid gland. The dominant symptoms were: breathing difficulties, hoarse voice and the enlargement of the thyroid. An ultrasound examination was performedbefore surgery on the neck, which showed a multinodular thyroid,with compromised and compressed trachea to the right and rear. Anemergency surgical procedure was performed to reduce the tumor.Pathohistological diagnosis confirmed diffuse large B cell lymphoma.The aim of the study was to present a patient with a thyroid lymphoma, who had previously not had any immunological changes to the gland,that is, she had not had any chronic lymphocyte thyroiditis, but due to the compressive syndrome it was necessary to perform an emergencysurgical procedure to reduce the tumor.

    B cell lymphoma with features intermediate between diffuse large B cell lymphoma and Burkitt lymphoma (DLBCL/BL) is a new lymphoma entity which is recognized in the current World Health Organization (WHO) classification (2008). We report a case of a primary central nervous system lymphoma (PCNSL) with findings consistent with DLBCL/BL. It is characterized by a very aggressive clinical course, and a widespread multifocal involvement of the CNS. Our case shows that a DLBCL/BL can manifest in the CNS alone without any systemic involvement.

    Introduction: To evaluate the computed tomographic (CT) findings of primary thyroid lymphoma. Methods and material: The clinicopathological data and CT images of nine patients with primary thyroid lymphoma were retrospectively reviewed. The CT appearances were classified into three types: type 1, a solitary nodule surrounded by normal thyroid tissue; type 2, multiple nodules in the thyroid, and type 3, a homogeneously enlarged both thyroid glands with a reduced attenuation with or without peripheral thin hyperattenuating thyroid tissue. Results: All patients had a rapidly enlarging thyroid mass and coexistent Hashimoto's thyroiditis. One patient showed type 1 pattern, three type 2, and five type 3. Six patients had homogeneous tumor isoattenuating to surrounding muscles. The tumors had a strong tendency to compress normal remnant thyroid and the surrounding structure without invasion. Conclusion: Primary thyroid lymphoma should be included in the differential diagnosis when old female had a homogeneous thyroidal mass isoattenuating to muscles, which does not invade surrounding structures.

    The follicular lymphoma, exactly, the cancer of follicular center and germinal center B lymphocytes, is reviewed on its immunological, pathological and genetic diagnoses, epidemiology, clinical symptoms, prognosis factors, therapy and assessment of therapy effects together with respective therapy of follicular small cleaved and follicular mixed small cleaved and large cell lymphoma of grade I, II; and of follicular large cell lymphoma of grade III. The therapy is essentially the radiotherapy combined with chemotherapy and others, of which effect is mainly assessed by CT. In clinical application grade II, III, irradiation of X- and electron rays and their combination is done in a fractionated manner with the maximal dose of around 35 Gy. In clinical disease grade II, III, regimen of irradiation is not fixed. In III, IV, chemotherapy and immunotherapy are major. In recurrence and malignant transformation, there is a report of large dose chemotherapy + whole body irradiation + bone marrow transplantation. (K.H.)

    Full Text Available Victoria Mary Lendrum CohenSt. Bartholomew’s and Moorfields Eye Hospital, London UKAbstract: Most lymphomas that involve the ocular adnexal structure are low grade, B cell, non-Hodgkin’s lymphomas. The treatment depends upon the grade and stage of the disease. High grade lymhoma requires treatment with systemic chemotherapy whereas the localized low grade (extranodal marginal zone lymphoma can be successfully managed with local radiotherapy. Chlamydia psittaci infection is associated with low grade ocular lymphoma; however there is wide geographic variation in the strength of this association. Blanket antibiotic therapy is not advised unless there is proof of an infective agent. The monoclonal antibody, rituximab, may be successful for CD20 positive lymphoma, although it is likely that rituximab will have better long-term results when used in combination with systemic chemotherapy.Keywords: ocular adnexal lymphoma, mucosa associated lymphoid tissue, extranodal marginal zone lymphoma, Chlamydia psittaci, rituximab, radiotherapy, chemotherapy

    Optimal lymphoma management requires accurate pretreatment staging and reliable assessment of response, both during and after therapy. Positron emission tomography with computerized tomography (PET/CT) combines functional and anatomical imaging and provides the most sensitive and accurate methods...... for lymphoma imaging. New guidelines for lymphoma imaging and recently revised criteria for lymphoma staging and response assessment recommend PET/CT staging, treatment monitoring, and response evaluation in all FDG-avid lymphomas, while CT remains the method of choice for non-FDG-avid histologies. Since...... interim PET imaging has high prognostic value in lymphoma, a number of trials investigate PET-based, response-adapted therapy for non-Hodgkin lymphomas (NHL). PET response is the main determinant of response according to the new response criteria, but PET/CT has little or no role in routine surveillance...

PetScreen developed a lymphoma blood test using serum samples collected from several veterinary practices. The samples were fractionated and analysed by mass spectrometry. Two protein peaks, with the highest diagnostic power, were selected and further identified as acute phase proteins, C-Reactive Protein and Haptoglobin. Data mining methods were then applied to the collected data for the development of an online computer-assisted veterinary diagnostic tool. The generated software can be used as a diagnostic, monitoring and screening tool. Initially, the diagnosis of lymphoma was formulated as a classification problem and then later refined as a lymphoma risk estimation. Three methods, decision trees, kNN and probability density evaluation, were used for classification and risk estimation and several preprocessing approaches were implemented to create the diagnostic system. For the differential diagnosis the best solution gave a sensitivity and specificity of 83.5% and 77%, respectively (using three input features, CRP, Haptoglobin and standard clinical symptom). For the screening task, the decision tree method provided the best result, with sensitivity and specificity of 81.4% and >99%, respectively (using the same input features). Furthermore, the development and application of new techniques for the generation of risk maps allowed their user-friendly visualization.

    Immunohistochemical determination of p63 protein is frequently used in the pathologic diagnosis of nonhematological solid tumors. In malignant hematological disease, p63 expression has been reported in 22% of follicular lymphoma, about 35% of diffuse large B-cell lymphoma, 23% of chronic lymphocytic leukemia, and in some cases of blast crisis of chronic myelogenous leukemia. Anaplastic large cell lymphoma is a rare disease that accounts for less than 5% of all cases of non-Hodgkin's lymphoma. There is little information concerning p63 expression in this specific type of lymphoma. In some cases, the morphological and phenotypic features between anaplastic large cell lymphoma and classical Hodgkin's lymphoma are similar, making this differential diagnosis challenging. We studied p63 expression using a tissue microarray approach in 154 cases of anaplastic large cell lymphoma, including 38% anaplastic large cell kinase positive and 62% anaplastic large cell kinase negative, and 58 Hodgkin's lymphoma cases. Sixty-eight cases of anaplastic large cell lymphoma (44%) showed p63 nuclear positivity (41% of anaplastic large cell kinase positive and 47% of anaplastic large cell kinase negative). Of 130 cases of systemic-anaplastic large cell lymphoma, 42% showed p63 positivity. The neoplastic cells expressed p63 in 38% of the cases of CD45-negative/anaplastic large cell kinase-negative null cell-type anaplastic large cell lymphoma, a subgroup that offers the most difficulties in the differential diagnosis with classical Hodgkin's lymphoma. In contrast, none of the cases of classical Hodgkin's lymphoma demonstrated any p63 expression. These results demonstrate that p63 protein expression is frequently expressed in a subset of anaplastic large cell lymphoma cases and may be used as a potential tool in the differential diagnosis between anaplastic large cell lymphoma and classical Hodgkin's lymphoma.

    Among 4325 goiter patients first examined in the period from February 1980 to April 1982, 5 cases of lymphoma appearing primarily in the thyroid gland were discovered incidentally. During the same period 13 patients with anaplastic thyroid carcinoma were observed. 5 of 23 systematically examined patients who had already known extrahyroidal malignant non-Hodgkin's lymphomas and lymphoma patient examined by chance exhibited a secondary thyroid gland lymphoma, that is, a secondary infiltration of the enlarged thyroid. Altogether, 29 patients with malignant non-Hodgkin's lymphoma (Kiel classification) were examined. Of 8 Hodgkin's disease patients none showed clinical or cytological evidence of thyroid infiltration. The clinical symptoms of primary lymphoma of the thyroid gland corresponded to those of anaplastic thyroid carcinoma. A positive differential diagnosis of the two tumours succeeded cytologically. The secondary lymphoma of the thyroid also could only be diagnosed cytologically. Patients with Hodgkin's lymphoma and non-Hodgkin's lymphoma were always found to be euthyroid. Autoimmunological phenomena (antimicrosomal and antithyreoglobulin autoantibodies) as an indicator of lymphocytic thyroiditis could only be examined among 11 patients. Two patients with secondary lymphoma of the thyroid showed positive titers. A small cell anaplastic thyroid carcinoma could not be diagnosed in any of 37 patients with anaplastic thyroid cancer out of an enlarged patient collective (period under consideration: 1976-1982).

    A differential diagnosis of acute and subacute progressive dementias includes malignant lymphoma of the brain. We reviewed primary central nervous system lymphoma (PCNSL), intravascular lymphomatosis (IVL), lymphomatosis cerebri, and the relapse and invasion of systemic lymphomas. PCNSL is confined to the central nervous system; the infiltration and compression by the lymphoma result in adverse neurological symptoms. IVL is a rare form of malignant lymphoma that is characterized by the proliferation of primarily B-cell type lymphoma cells within the blood vessels of various organs. This causes ischemia and results in the associated neurological symptoms. Medical history and neuroimaging studies provide crucial informations to distinguish the lymphomas from other diseases that cause dementia, such an Alzheimer's disease. MRI imaging of the brain using contrast agent, and the biopsy of diseased tissues are essential for the diagnosis of the lymphomas. A histopathological examination is the most effective way to diagnose malignant lymphomas of the brain. Presently, the treatment of choice for PCNSL is the intravenous administration of high dose methotrexate with and without radiation therapy. Futhermore, Rituximab-containing chemotherapy has proved to greatly improve the prognosis of IVL. A better outcome can be achieved with the earlier diagnosis and treatment of the malignant lymphoma of the brain.

    Full Text Available B-cell lymphomas with concurrent IGH-BCL2 and MYC rearrangements, also known as “double hit” lymphomas (DHL, are rare neoplasms characterized by highly aggressive clinical behavior, complex karyotypes, and a spectrum of pathological features overlapping with Burkitt lymphoma (BL and diffuse large B-cell lymphoma (DLBCL. Primary renal lymphoma (PRL by definition is a renal lymphoma without evidence of systemic involvement. PRL is extremely rare with less than 100 cases of both Hodgkin disease and non-Hodgkin lymphoma reported in literature. Double hit lymphomas have extremely poor prognosis, and high resistance to intensive chemotherapy, including high-dose chemotherapy. We describe a very rare case of DHL arising in kidney as PRL in whom concurrent IGH-BCL2 and MYC rearrangements were detected. [J Interdiscipl Histopathol 2013; 1(2.000: 93-97

    Full Text Available Background: The histological categorization of lymphoma has been a source of controversy for many years for both clinicians and pathologists. Clinicopathologic information of gastrointestinal lymphomas in Indian subcontinent is lacking. We studied histopathological spectrum of Primary Gastrointestinal Lymphomas (PGIL and attempted to classify the G.I. lymphomas based on the recent WHO classification in to major histological types and immunological categories. Material and Methods: This study was done to evaluate the clinicopathological pattern of 100 cases with a histopathological diagnosis of primary gastrointestinal lymphoma at a tertiary care hospital. All patients of primary gastrointestinal lymphomas were included with the help of medical records over a 11-years period that is, January 2005 to December 2015. Results: The study included 100 cases (60 males, 40 females; mean age 51.43 years; age range 4.5-90 years . The disease involved stomach in 82 (82%, small intestine in 8 (8%, large bowel and rectum in 8 (8%, gall bladder in 1 (1% and oesophagus in 1 (1%. 82 (82% of the 100 cases were Diffuse Large B cell lymphomas; 12 (12% were Extra Nodal Marginal Zone Lymphomas (ENMZL of MALT type 2 (2% IPSID 2 (2% of Mantle cell lymphoma morphology, 1 (1% Burkitt's and 1(1% enteropathy associated T cell lymphoma. The commonest presenting symptom was abdominal pain. 99 (99% of 100 tumours were classified as B-cell lymphomas immunohistochemically and majority exhibited monoclonal light chain restriction on kappa/lambda staining. In addition; Burkitt's lymphoma showed positivity for CD 10. One tumour (1% showed positivity for T-cell markers. The data demonstrated that primary GI NHL is more common among males, mainly in their fifth decade. Abdominal pain is the most common presenting symptom, with stomach being the most commonly involved site.

    Full Text Available Lymphoma of the salivary gland accounts for 5% of cases of extranodal lymphoma and 10% of malignant salivary gland tumors. Most primary salivary gland lymphomas are B marginal zone lymphomas arising on a background of sialadenitis associated with an autoimmune disorder such as Sjorgen′s syndrome. This report describes a case of primary B-cell lymphoma arising in the parotid gland in a middle-aged female, which was not associated with an autoimmune disorder. Immunohistochemistry studies confirmed the clonal B-cell nature of the tumor. This case highlights the fact that B-cell lymphoma in the salivary gland can go unrecognized due to its non-specific symptoms and requires immunohistochemistry studies for confirmation. We present this case for its rarity.

    Full Text Available Primary thyroid lymphomas are rare neoplasms comprising of 1-5% of thyroid malignancies. These are predominantly B-cell in origin. Here, we report a case of 60 years lady, a known case of lymphocytic thyroiditis, diagnosed as thyroid lymphoma (diffuse large B-cell on fine needle aspiration and confirmed histopathogically and immunohistochemically. She presented with a sudden increase in thyroid swelling. Fine needle aspiration performed showed highly cellular smears comprising predominantly of the monomorphic population of medium to large sized lymphoid cells with high nuclear/cytoplasmic ratio and scant cytoplasm. A possibility of thyroid lymphoma possibly diffuse large B-cell lymphoma was suggested which was later confirmed on biopsy. Fine needle aspiration provides an easy mode for diagnosing large cell lymphoma like diffuse large B-cell. Hence, an early diagnosis is possible for a timely intervention. Also, cases of lymphocytic thyroiditis should be regularly followed for the development of lymphoma.

    An 18-year-old African-American female presented with an episode of syncope. Initial investigations revealed large lung mass with invasion into right atrium along with lesions in kidneys and liver. Patient also developed superior vena cava syndrome due to lung mass. Biopsy of lung mass revealed diagnosis of composite lymphoma with involvement by primary mediastinal B-cell lymphoma (PMBCL) and classical Hodgkin lymphoma. Patient was started on dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin and rituximab (EPOCH-R) with complete response to treatment. This case represents an extremely rare type of aggressive lymphoma and can guide clinicians in managing such cases since there are no standard guidelines for treatment. To the best of our knowledge, this is the first reported case of composite lymphoma of PMBCL and classical Hodgkin lymphoma successfully treated with dose-adjusted EPOCH-R regimen.

    Patients with B cell non-Hodgkin's lymphomas (B-NHLs) are known to be at risk of developing psychological disorders. The aims of this study were to measure the incidence of psychotropic drug use during the diagnosis and the active treatment phase in comparison with controls from the general population, and to identify factors associated with this use. B-NHL patients were selected through the French national health insurance database in the Midi-Pyrénées region (southwestern France) from January 1, 2011, to April 31, 2013. Patients with a previous history of B-NHL and/or psychotropic drug treatment were excluded. Among 745 newly diagnosed B-NHL patients, psychotropic treatment was initiated in 31.5 % (95 % CI [28.1-34.9]), compared to 7.6 % (95 % CI [7.57-7.64]) in the general population during the same period. This incidence was comparable in colorectal cancer patients (33.5 %) but higher than that in patients with myocardial infarction (23.5 %) or with a first knee replacement surgery (22.4 %). Anxiolytics and hypnotics were the most frequently used drugs. Median duration of treatment was 37 days for anxiolytics and 58 days for hypnotics, with 20.8 % of patients remaining under treatment at 8 months. Factors associated with psychotropic drug initiation were young age, health care consumption in the year before diagnosis, and initial care at a university hospital. The high rate of psychotropic drug initiation reflects a high level of anxiety at the initial phase of B-NHL patients' trajectory. This pharmacoepidemiological study reveals inappropriate use in some patients, which should now be investigated in lymphoma survivorship.

    Full Text Available There are many therapies available for the management of low-grade lymphoma. With follicular lymphoma, for example, combination of chemotherapy and rituximab (immuno-chemo - therapy and consecutive maintenance therapy for 2 years is the current standard of care. To date, the most widely used regimen seems to be rituximab combined with cyclo phosphamide, doxorubicin, vincristine, and prednisone (RCHOP. Substitution of liposomal doxorubicin in place of conventional doxorubicin may improve outcomes in this indication, although evidence for its use in low-grade lymphoma is not as relevant as in aggressive lymphoma. Bendamustine, in combination with rituximab, has shown very good efficacy and tolerability in several lymphoma types, particularly follicular lymphoma and other low-grade lymphomas. Other combinations, such as those including bortezomib and lenalidomide, are under investigation in low-grade lymphoma, and the duration of rituximab maintenance therapy following bendamustine−rituximab-containing induction is being researched by the German Study Group for Indolent Lymphoma (StiL.

    In follicular lymphoma, nonmalignant immune cells are important. Follicular lymphoma depends on CD4+ cells, but CD8+ cells counteract it. We hypothesized that the presence of follicular lymphoma is associated with higher CD4+ than CD8+ cell numbers in the tumor microenvironment but not in the immune system.

    2016-11-01

    Full Text Available Follicular lymphoma(FL is the most common indolent non-Hodgkin lymphoma and constitutes 15% to 30% of lymphoma diagnoses. The natural history of the disease is characterized by recurrent relapses and progressively shorter remissions with a median survival of 10yrs. The impossibility of a chieving a definite cure, have prompted investigations into the possible role of more effective and less toxic strategies with innovative therapeutic agents.  Recently Casulo et al demonstrated that approximately 20% of patients with FL actually relapse within 2 years after achieving remission with R-CHOP and have a poor prognosis. It is conceivable that this particularly chemoresistant population would benefit from specifically targeting the biologic and genetic factors that likely contribute to their poor prognosis. Evolving strategies for difficult to treat FL patients have recently considered  immunomodulatory agents, new monoclonal antibodies as well as drugs targeting selective intracellular pathways. The importance of targeting the microenvironment together with the malignant FL cell has been particularly underscored. We review the most promising approaches, such as the combination of anti-CD20 antibodies with immunomodulatory drugs (Lenalidomide, with mAbs directed against other surface antigens such as CD22 and CD23 (epratuzumab, lumiliximab, with immunomodulatory antibodies such as PD-1, or with inhibitors of key steps in the B-cell receptor pathway signaling such as PI3K inibithors(idelalisib, duvelisib. Another highly attractive approach is the application of the bi-specific T-cell engaging (BiTE antibody blinatumomab which targets both CD19 and CD3 antigens. Moreover, we highlight the potential of these therapies,  taking into account their toxicity. Of course we must wait for Phase III trials results to confirm the benefit of these new treatment strategies toward a new era of chemotherapy-free treatment for follicular lymphoma.

    2009-01-01

    Composite lymphomas are rare and defined as hematopoietic neoplasms with more than 1 malignant lymphomatous clone showing different phenotypic features. Of all possible combinations between non-Hodgkin lymphomas, B cell or T cell, and Hodgkin lymphoma, the least frequent are the ones combining T-cell non-Hodgkin lymphoma and classic Hodgkin lymphoma. We report a case of a 55-year-old woman with cervical and mediastinal lymphadenopathy, fever, weight loss, and night sweats. A cervical lymph node biopsy revealed a composite lymphoma with classic Hodgkin lymphoma and peripheral T-cell lymphoma components. The bone marrow was not involved. The patient refused treatment and died of disease progression 2 months after diagnosis. The biopsied lymph node showed 2 distinct populations, one composed of large cells including typical Reed-Sternberg cells and their variants, with expression of CD30, CD15, PAX5, and LMP-1. The other component was more abundant and comprised polymorphic medium-sized cells with convoluted nuclei; CD3, CD5, CD2, and CD4 expression; and negativity for CD30, cytotoxic granules, and B-cell markers. Epstein-Barr virus DNA of subtype A was identified only in the Hodgkin cells. Clonal T-cell receptor gamma and beta gene rearrangements were detected in the T-cell component, whereas monoclonal immunoglobulin H gene rearrangement was found in the Hodgkin cells.

    Full Text Available Apart from its well known role as an etiological agent for non-A and non-B viral hepatitis, there is growing evidence that hepatitis C virus is associated to B-cell non-Hodgkin lymphoma. The association between HCV and lymphoproliferative disorders has been recently postulated based on epidemiological data, biological studies and clinical observations. Although various subtypes of lymphomas appear to be associated to HCV, diffuse large B-cell lymphoma, small lymphocytic lymphoma/chronic lymphocytic leukemia and marginal zone lymphoma appeared to be particularly represented among HCV-positive patients.  The causative role of HCV in those disorders has been further supported by the response to anti-viral therapy. Despite a better understanding of pathophysiological processes at stake leading from HCV infection to overt lymphoma, many issues still need to be further elucidated. Although HCV has been demonstrated to directly infect peripheral blood mononuclear cells both in vitro and, in some cases, in vivo, a strong body of evidence rather supports the hypothesis of an indirect transformation mechanism by which sustained antigenic stimulation leads from oligoclonal to monoclonal expansion and sometimes to lymphoma, probably through secondary oncogenic events. Here, we review epidemiological and biological studies, as well as clinical data on antiviral therapy, linking HCV-infection to B-cell non-Hodgkin lymphoma.

    Lymphomas are a heterogeneous group of diseases that arise from the constituent cells of the immune system or from their precursors. 18F-fludeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) is now the cornerstone of staging procedures in the state-of-the-art management of Hodgkin's disease and aggressive non-Hodgkin's lymphoma. It plays an important role in staging, restaging, prognostication, planning appropriate treatment strategies, monitoring therapy, and detecting recurrence. However, its role in indolent lymphomas is still unclear and calls for further investigational trials. The protean PET/CT manifestations of lymphoma necessitate a familiarity with the spectrum of imaging findings to enable accurate diagnosis. A meticulous evaluation of PET/CT findings, an understanding of its role in the management of lymphomas, and knowledge of its limitations are mandatory for the optimal utilization of this technique.

    Anaplastic large cell lymphoma and small lymphocytic lymphoma are two lymphoid malignancies with completely distinct morphologies and natural histories. We present a rare case of composite anaplastic large cell lymphoma and small lymphocytic lymphoma in an inguinal lymph node of an otherwise healthy 47-year-old male patient. Immunohistochemical and molecular studies identified the two populations clearly. Their separation is imperative as anaplastic large cell lymphoma can be an aggressive neoplasm and easily overlooked in cases of small lymphocytic lymphoma with a small population of anaplastic large cell lymphoma cells.

    Full Text Available HIV-associated lymphoproliferative disorders represent a heterogeneous group of diseases, arising in the presence of HIV-associated immunodeficiency. The overall prevalence of HIV-associated lymphoma is significantly higher compared to that of the general population and it continues to be relevant even after the wide availability of highly active antiretroviral therapy (HAART (1. Moreover, they still represent one of the most frequent cause of death in HIV-infected patients. Epstein–Barr virus (EBV, a γ-Herpesviruses, is involved in human lymphomagenesis, particularly in HIV immunocompromised patients.

    Dose and time intensifications of chemotherapy improved the outcome of lymphoma therapy. However, recent study results show that too intense therapies can result in inferior tumour control. We hypothesise that the immune system plays a key role in controlling residual tumour cells after treatment. More intense therapies result in a stronger depletion of immune cells allowing an early re-growth of the tumour.We propose a differential equations model of the dynamics and interactions of tumour and immune cells under chemotherapy. Major model features are an exponential tumour growth, a modulation of the production of effector cells by the presence of the tumour (immunogenicity), and mutual destruction of tumour and immune cells. Chemotherapy causes damage to both, immune and tumour cells. Growth rate, chemosensitivity, immunogenicity, and initial size of the tumour are assumed to be patient-specific, resulting in heterogeneity regarding therapy outcome. Maximum-entropy distributions of these parameters were estimated on the basis of clinical survival data. The resulting model can explain the outcome of five different chemotherapeutic regimens and corresponding hazard-ratios.We conclude that our model explains observed paradox effects in lymphoma therapy by the simple assumption of a relevant anti-tumour effect of the immune system. Heterogeneity of therapy outcomes can be explained by distributions of model parameters, which can be estimated on the basis of clinical survival data. We demonstrate how the model can be used to make predictions regarding yet untested therapy options.

    2017-09-26

    Acute lymphoblastic lymphoma (ALL) was a malignant hematological disease in childhood but rarely, initially involved epidural compartment in adult. A 20-year-old male presented with progressive osphyalgia for 2 months and left lower motor weakness for 2 weeks with constipation. Physical examination revealed decreased muscle strength and numbness of left lower limb, and abnormal gait. Contrasted MRI showed multiple vertebrae of hypointense T1 signals (C2/C4/C7/T5/T8/T9/T12/L2/L4) and an intraspinal epidural lesion (L2-4). Subtotal resection was achieved. Histopathology suggested malignant B-cell lymphoma with Ki-67 of 90% and positivity of leukocyte common antigen (LCA). A bone marrow biopsy was unequivocally diagnostic of B-cell ALL followed by chemotherapy (Methotrexate) and partial recovery was observed. The present case was the oldest patient with epidural ALL. The radiographic changes in multiple vertebrae suggested metabolic, hematological, or granulomatous disease. The marrow biopsy was necessary if without hypercalcemia and abnormal peripheral blood examination. Accurate pathological diagnosis was essential. Copyright © 2017 Elsevier Inc. All rights reserved.

    2000-02-01

    Persons 65 years of age and older are the fastest growing segment of the United States population. Over the next 30 years they will comprise approximately 20% of the population. There will be a parallel rise in the number of patients with non-Hodgkin's lymphoma. Age has long been known to be an adverse prognostic factor. Clinical trials of older patients are complicated by the effect of comorbid illness, particularly its effect on overall survival. CHOP (cyclophosphamide, Adriamycin, vincristine, prednisone) remains the standard therapy for all patients with aggressive non-Hodgkin's lymphoma. There are a number of regimens which may be beneficial for older patients with significant comorbidity and poor performance status. The randomized trials in the elderly has reaffirmed CHOP and emphasize the need for adequate dosing, maintaining schedule and anthracyclines. Relapsed patients have a poor prognosis but selected fit older patients may benefit from aggressive reinduction regimens and possibly bone marrow transplantation. Future research should include defining the role of comorbidity, measurement of organ dysfunction and assessment of performance status with geriatric functional scales. New drug treatments should also be explored.

    Objective: To investigate the clinical features and the reason of misdiagnosis of consolidative primary pulmonary lymphoma. Methods: Retrospective study was conducted for three cases with consolidative primary pulmonary lymphoma(PPL). The relevant literatures of primary pulmonary lymphoma in recent years were also reviewed. Results: All patients had been misdiagnosed for a long time due to the non-specific clinical features. Conclusion: Consolidative PPL is difficult to diagnose and is misdiagnosed frequently in clinic. Definitive diagnosis of PPL requires an adequate biopsy specimen. The most important prognostic factor is the histology.

    2011-09-01

    Pulmonary Langerhans histiocytosis (PLH) is a rare disease due to the accumulation of Langerhans cells at the level of the bronchioles. These dendritic immunocytes form granulomata and destroy the wall of the airway. We report a case of PLH developing at the same time as Hodgkin's lymphoma in a young woman who smoked tobacco and cannabis. We observed a complete remission of the PLH lesions parallel to the remission of the Hodgkin's lymphoma after chemotherapy, in the absence of any change in the consumption of tobacco and cannabis. This observation leads us to discuss the potential relationships between PLH on one hand, and smoking, the lymphoma and its treatment on the other.

    We report a case of primary multifocal osseous lymphoma in a 6-year-old girl presenting with multifocal osteolytic lesions without systemic symptoms or identifiable non-osseous primary tumor. The differential diagnoses for such a presentation include histiocytosis X, chronic recurrent multifocal osteomyelitis, acute lymphoblastic leukemia, metastatic disease, and primary bone lymphoma. Although non-Hodgkin lymphoma is common in the pediatric population, its presentation as a primary bone tumor, especially with multifocal disease, is extremely rare and is frequently misdiagnosed. We hope that awareness of this entity will help radiologists achieve timely diagnosis and intervention. (orig.)

    The thesis is based on seven publications in English and a review of the literature. The studies were carried out to contribute to the understanding of Hodgkin lymphoma epidemiology through descriptions of its occurrence and its association with Epstein-Barr virus (EBV) infection presenting as infectious mononucleosis. The investigations were supported by the Danish Cancer Society, the Swedish Cancer Society, the Danish Cancer Research Foundation, the Nordic Cancer Union, the Lundbeck Foundation, Plan Danmark, Danish National Research Foundation, Lily Benthine Lund's Foundation, Aase og Ejnar Danielsen's Foundation, Grosserer L. F. Foght's Foundation, the Leukaemia Reseach Fund, the Kay Kendall Leukaemia Fund, and the U.S. National Institutes of Health. The work was carried out in the period 1999-2010 during my employment at the Department of Epidemiology Research at Statens Serum Institut. The employed study designs included population-based incidence surveys of Hodgkin lymphoma in the Nordic countries and in Singapore, register-based cohort studies to characterise the pattern of cancer occurrence in patients with infectious mononucleosis and their first degree relatives, a register-based cohort and a population-based case-control study to characterise the association between infectious mononucleosis and Hodgkin lymphoma taking tumour EBV-status into consideration, and a case-series analysis to assess the association between HLA class I alleles and EBV-positive and EBV-negative Hodgkin lymphomas. Analyses of Nordic incidence data demonstrated that the occurrence of Hodgkin lymphoma had increased markedly younger adults in the period 1978-97, whereas it had decreased among older adults. In combination, these developments led to an accentuation of the younger adult Hodgkin lymphoma incidence peak, which has been a hallmark of Hodgkin lymphoma epidemiology in the Western hemisphere for more than a half century. The opposing incidence trends in younger and older

    2012-01-01

    Full Text Available 18-Fluoro-deoxyglucose positron emission tomography/computerised tomography (FDG PET/CT is commonly used in the management of patients with lymphomas and is recommended for both initial staging and response assessment after treatment in patients with diffuse large B-cell lymphoma and Hodgkin lymphoma. Despite the FDG avidity of follicular lymphoma (FL, FDG PET/CT is not yet applied in standard clinical practice for patients with FL. However, FDG PET/CT is more accurate than conventional imaging for initial staging, often prompting significant management change, and allows noninvasive characterization to guide assessment of high-grade transformation. For restaging, FDG PET/CT assists in distinguishing between scar tissue and viable tumors in residual masses and a positive PET after induction treatment would seem to predict a shorter progression-free survival.

  20. Nodular lymphocyte-predominant Hodgkin lymphoma.

    Savage, Kerry J; Mottok, Anja; Fanale, Michelle

    2016-07-01

    Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare subtype of Hodgkin lymphoma with distinct clinicopathologic features. It is typified by the presence of lymphocyte predominant (LP) cells, which are CD20(+) but CD15(-) and CD30(-) and are found scattered amongst small B lymphocytes arranged in a nodular pattern. Despite frequent and often late or multiple relapses, the prognosis of NLPHL is very favorable. There is an inherent risk of secondary aggressive non-Hodgkin lymphoma (NHL) and studies support that risk is highest in those with splenic involvement at presentation. Given disease rarity, the optimal management is unclear and opinions differ as to whether treatment paradigms should be similar to or differ from those for classical Hodgkin lymphoma (CHL). This review provides an overview of the existing literature describing pathological subtypes, outcome and treatment approaches for NLPHL.

    2017-10-01

    Classical Hodgkin lymphoma (cHL) is the most common hematological malignancy in young adults and can be cured in most cases. However, relapsed and refractory Hodgkin lymphoma, certain patient groups, such as elderly patients, and toxicity of first-line treatment still pose significant challenges. Consequently, new treatment options are needed. Recently, many new treatment concepts have been evaluated in clinical trials. Targeted drug-antibody conjugates and immune checkpoint inhibitors have decisively changed treatment approaches. This review aims to give a comprehensive overview of novel agents in Hodgkin lymphoma that have been recently or are currently being evaluated in clinical trials. In addition to dedicated sections on brentuximab vedotin (BV) and immune checkpoint inhibitors, other emerging substances and concepts are discussed. In doing so, this review compares trial results regarding safety and efficacy. A special focus lies on the effect novel agents will have on the different treatment settings faced by clinicians involved in the treatment of Hodgkin lymphoma.

    Double-hit lymphomas (DHLs) characterize a unique subset of B-cell non-Hodgkin lymphomas. DHL typically presents in older adults with high-risk clinical features. This entity carries a significantly inferior prognosis compared with typical cases of diffuse large B-cell lymphoma; however, emerging literature can identify discrete clinical features within DHL that are associated with a favorable prognosis. Emerging literature is also demonstrating that intensive upfront treatment strategies may improve outcome. Diagnosis, prognostication, and management of DHL are reviewed, as well as potential future directions incorporating novel biologically targeted therapies. Finally, double-expressing lymphomas (DELs) will be discussed and contrasted with DHL. Copyright © 2016 Elsevier Inc. All rights reserved.

    2014-09-01

    Full Text Available Hypotension is an extremely rare manifestation of Hodgkin lymphoma. We report the case of a patient who presented with new onset hypotension and was diagnosed with urosepsis and septic shock requiring pressor support for maintaining his blood pressure. computed tomography (CT scan of abdomen showed liver lesions, which were new on comparison with a CT abdomen done 3 weeks back. Biopsy of the liver lesions and subsequently a bone marrow biopsy showed large atypical Reed-Sternberg cells, positive for CD15 and CD 30 and negative for CD45, CD3 and CD20 on immunohistochemical staining, hence establishing the diagnosis of Hodgkin lymphoma. The mechanism involved in Hodgkin lymphoma causing hypotension remains anecdotal, but since it is mostly seen in patients with advanced Hodgkin lymphoma, it is hypothetically related to a complex interaction between cytokines and mediators of vasodilatation. Here we review relevant literature pertaining to presentation and pathogenesis of this elusive and rare association.

  11. NKT Cell Responses to B Cell Lymphoma

    2014-04-01

    Full Text Available Natural killer T (NKT cells are a unique subset of CD1d-restricted T lymphocytes that express characteristics of both T cells and natural killer cells. NKT cells mediate tumor immune-surveillance; however, NKT cells are numerically reduced and functionally impaired in lymphoma patients. Many hematologic malignancies express CD1d molecules and co-stimulatory proteins needed to induce anti-tumor immunity by NKT cells, yet most tumors are poorly immunogenic. In this study, we sought to investigate NKT cell responses to B cell lymphoma. In the presence of exogenous antigen, both mouse and human NKT cell lines produce cytokines following stimulation by B cell lymphoma lines. NKT cell populations were examined ex vivo in mouse models of spontaneous B cell lymphoma, and it was found that during early stages, NKT cell responses were enhanced in lymphoma-bearing animals compared to disease-free animals. In contrast, in lymphoma-bearing animals with splenomegaly and lymphadenopathy, NKT cells were functionally impaired. In a mouse model of blastoid variant mantle cell lymphoma, treatment of tumor-bearing mice with a potent NKT cell agonist, α-galactosylceramide (α-GalCer, resulted in a significant decrease in disease pathology. Ex vivo studies demonstrated that NKT cells from α-GalCer treated mice produced IFN-γ following α-GalCer restimulation, unlike NKT cells from vehicle-control treated mice. These data demonstrate an important role for NKT cells in the immune response to an aggressive hematologic malignancy like mantle cell lymphoma.

    2016-10-01

    Despite the improvement in prognosis since the advent of rituximab, follicular lymphoma is still incurable and remains the cause of death of most afflicted patients. With the expanding knowledge of the pathogenesis of B-cell malignancies, in the last few years a plethora of new therapies acting through a variety of mechanisms have shown promising results. This review attempts to analyze the evidence available on these new drugs, which include new monoclonal antibodies and immunoconjugates, the anti-angiogenic and immunomodulatory agent lenalidomide, the proteasome inhibitor bortezomib, inhibitors of B-cell receptor pathway enzymes, such as ibrutinib, idelalisib, duvelisib and entospletinib, BCL2 inhibitors and checkpoint inhibitors. We conclude that despite the high expectations around the new therapeutic options for patients with refractory disease, these new drugs have side effects that require caution with their use, particularly in light of the still short follow up and the lack of both randomized trials and data on combination regimens.

    2008-03-01

    Full Text Available Abstract Background Hodgkin's disease (HD most commonly presents with progressive painless enlargement of peripheral lymph nodes, especially around the cervical region. A few children have systemic symptoms and weight loss. At the time of diagnosis, osseous involvement is uncommon Case presentation A case is described of Primary Multifocal Osseous Hodgkin's Lymphoma in a seven-year-old boy. He presented with a painful swelling in the sternum, and further investigations revealed deposits in his L1 vertebra, the left sacro-iliac joint and the right acetabulum. Conclusion The clinical, radiological and histological features of this disease can mimic other medical conditions, including Tuberculosis, making the diagnosis difficult and often leading to delays in treatment. This is a very rare condition and we believe this to be the youngest reported case in the literature.

    2014-01-01

    Full Text Available Introduction. Primary hepatic lymphoma is an unusual malignancy and is very difficult to diagnose promptly. An intrigue case presenting with cholestatic jaundice is reviewed and main disease characteristics are further discussed. Case Report. A 70-year-old male presented with dull right upper quadrant abdominal pain and mild cholestatic jaundice. Initial evaluation revealed mildly elevated liver function tests and normal tumor markers, while imaging with an abdominal CT-scan showed multiple hypodense nodules in both liver lobes. First impression of metastatic deposits from gastrointestinal origin was not confirmed by endoscopic means. After CT-guided biopsy, primary diffuse large B-cells non-Hodgkin lymphoma was revealed. Appropriate chemotherapy improved patient’s condition markedly. Discussion. Primary hepatic lymphoma is a rare form of extranodal lymphomas, accounting for less than 1% of all extranodal lymphomas in general. In order to define the condition as PHL, liver has to be the only site of lymphoma occurrence or to be involved in a major degree with minimal nonliver disease. Most PHLs are of B-cell origin with large cells as the main cell type.

  20. Primary Hepatosplenic Large B-Cell Lymphoma

    2008-03-01

    Full Text Available Diffuse large B-cell lymphoma is the most common form of lymphoma. It usually begins in the lymph nodes; up to 40% may have an extranodal presentation. According to a definition of primary extranodal lymphoma with presentation only in extranodal sites, there are reports of large B-cell lymphomas limited to liver or spleen as separate entities, and to date there have been only three documented cases of primary hepatosplenic presentation. This paper reports a fourth case. Due to a review of the literature and the clinical course of the case reported, we conclude that primary hepatosplenic large B-cell lymphoma has been found predominantly in females older than 60 years. The patients reported had <2 months of evolution prior to diagnosis, prominent B symptoms, splenomegaly in three and hepatomegaly in two, none with lymph node involvement. All had thrombocytopenia and abnormal liver function tests; three had anemia and elevated serum lactic dehydrogenase levels, two with hemophagocytosis in bone marrow. Because of the previously mentioned data, it can be stated that primary hepatosplenic lymphoma is an uncommon and aggressive form of disease that requires immediate recognition and treatment.

    2011-08-01

    Full Text Available Abstract Introduction Mucosa associated lymphoid tissue lymphomas are the most common lymphomas of the salivary glands. The benign lymphoepithelial lesion is also a lymphoproliferative disease that develops in the parotid gland. In the present case report, we describe one case of benign lymphoepithelial lesion with a subsequent low transformation to grade mucosa associated lymphoid tissue lymphoma appearing as a cystic mass in the parotid gland. Case presentation A 78-year-old Caucasian female smoker was referred to our clinic with a non-tender left facial swelling that had been present for approximately three years. The patient underwent resection of the left parotid gland with preservation of the left facial nerve through a preauricular incision. The pathology report was consistent with a low-grade marginal-zone B-cell non-Hodgkin lymphoma (mucosa associated lymphoid tissue lymphoma following benign lymphoepithelial lesion of the gland. Conclusions Salivary gland mucosa associated lymphoid tissue lymphoma should be considered in the differential diagnosis of cystic or bilateral salivary gland lesions. Parotidectomy is recommended in order to treat the tumor and to ensure histological diagnosis for further follow-up planning. Radiotherapy and chemotherapy should be considered in association with surgery in disseminated forms or after removal.

    Full Text Available An unusual and well-characterised case of composite lymphoma in the spleen and lymph node is presented. The simultaneous occurrence of mixed-cellularity Hodgkin's lymphoma (HL and follicular non-Hodgkin's lymphoma (NHL was demonstrated in a 66-year-old man admitted in our Service with anaemia, hepatosplenomegaly and multiple abdominal lymph nodes. The morphological study of the spleen and lymph node of the splenic hilum showed an infiltrate composed of two distinct neoplasias. The liver was involved by NHL infiltrate and the peripancreatic lymph node exhibited HL. The Reed-Sternberg (RS cells expressed CD 15 and CD 30, whereas the NHL cells presented standard immunohistochemical features of follicular lymphoma. To our knowledge, this is the fifth case report of concurrent spleen involvement by composite lymphoma. The incidence, clinicopathological and immunohistochemical features of this rare association are discussed.

    2012-05-01

    B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphoma, is a diagnostic provisional category in the World Health Organization (WHO) 2008 classification of lymphomas. This category was designed as a measure to accommodate borderline cases that cannot be reliably classified into a single distinct disease entity after all available morphological, immunophenotypical and molecular studies have been performed. Typically, these cases share features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphoma, or include characteristics of both lymphomas. The rarity of such cases poses a tremendous challenge to both pathologists and oncologists because its differential diagnosis has direct implications for management strategies. In this study, we present 10 cases of B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphoma and have organized the criteria described by the WHO into four patterns along with detailed clinical, morphological and immunophenotypic characterization and outcome data. Our findings show a male preponderance, median age of 37 years and a mediastinal presentation in 80% of cases. All cases expressed at least two markers associated with B-cell lineage and good response to combination chemotherapy currently employed for non-Hodgkin lymphomas.

    Full Text Available CONTEXT: In Hodgkin's disease, each clinical or pathologic stage can be related to the extent of the area involved and predicts the next anatomical region at risk for tumor dissemination. OBJECTIVE: To determine the best prognostic factors that could predict survival in non-Hodgkin lymphoma cases. DESIGN: A retrospective study. LOCATION: Department of Hematology and Transfusion Medicine, Universidade Federal de São Paulo - Escola Paulista de Medicina. PARTICIPANTS: 142 patients with non-Hodgkin lymphoma diagnosed between February 1988 and March 1993. MAIN MEASUREMENTS: Histological subset, Sex, Age, Race, B symptoms, Performance status, Stage, Extranodal disease, Bulk disease, Mediastinal disease, CNS involvement, BM infiltration, Level of DHL, Immunophenotype. RESULTS: In the first study (113 patients, the following variables had a worse influence on survival: yellow race (P<0.1; ECOG II, III e IV (P<0.1 and extranodal disease (P<0.1 for high grade lymphomas; constitutional symptoms (P<0.1, ECOG II, III e IV (P<0.1 and involvement of CNS (P<0.1 for intermediate grade and the subtype lymphoplasmocytoid (P=0.0186 for low grade lymphomas. In the second survey (93 patients, when treatment was included, the variables related to NHL survival were: CNS involvement (P<0.1 for high grade lymphomas, constitutional symptoms (P<0.1, ECOG II, III, IV (P=0.0185 and also CNS involvement (P<0.1 for the intermediate group. There were no variables related to the survival for low-grade lymphomas. CONCLUSIONS: The intermediate grade lymphomas were more compatible with data found in the literature, probably because of the larger number of patients. In this specific case, the treatment did not have an influence on the survival.

    Background Pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is the most frequent type of non-Hodgkin's lymphoma (NHL) that primarily involves the lungs. It represents a rare entity accounting for less than 1%of all NHLs and the clinical features have yet to be clearly elucidated.Methods The clinicopathological features and radiological data of 23 patients with pulmonary MALT lymphoma confirmed by biopsy in Peking Union Medical College Hospital from January 2001 to December 2010 were retrospectively analyzed.Results At diagnosis,there were 15 women and 8 men. The median age was 55.1 years (range,37-73 years). One patient had a history of primary Sjoren's syndrome,another patient had a history of systemic lupus erythematosus (SLE)and secondary Sjoren's syndrome. One patient had a history of previous hematological malignancy (lymphomatoid papulosis in complete remission). In addition,one patient had simultaneous gastric and pulmonary involvement and one patient had simultaneous parotid gland and pulmonary involvement. The other 21 patients had disease localized within the lungs at the initial diagnosis. Among them,10 patients were asymptomatic while two had non-specific pulmonary symptoms. There were six patients with fever,four patients had low grade fever and two patients had moderate-high fever.The most common manifestations were cough (n=10),expectoration (n=8),exertional dyspnea (n=8),fatigue (n=7),body weight loss (n=6) and crackles (n=6). Blood tests showed low to moderate anemia in six cases,elevated erythrocyte semimentation rate (ESR) in 10 cases and only one patient had elevated lactate dehydrogenase (LDH). High resolution computed tomography (HRCT) of the chest revealed bilateral disease in 13 patients,air space consolidation with or without air bronchogram in 15 patients,lung nodules in 15 patients,patchy opacities in eight patients,lung mass in three patients and pleural effusion in five patients.

    2017-09-01

    T-cell lymphoma is a relatively rare hematologic malignancy that accounts for 10-20% of non-Hodgkin lymphomas. Treatment strategies for T-cell lymphomas are different from that for B-cell lymphomas and have poor prognoses. Among various subtypes of T-cell lymphomas, adult T-cell leukemia-lymphoma (ATL) has the worst prognosis. To achieve further improvement in the treatment outcome of T-cell lymphomas, several novel agents such as brentuximab vedotin, lenalidomide, romidepsin, and pralatrexate are actively being studied. Mogamulizumab, an anti-CC chemokine receptor 4 (CCR4) monoclonal antibody, is one of the promising agents for CCR4-positive T-cell lymphomas, especially for ATL. Areas covered: First, basic information about the current treatment strategy of T-cell lymphomas including ATL is described. Then, the authors discuss the current clinical development of mogamulizumab and its clinical implications for T-cell lymphomas. Expert opinion: Mogamulizumab has potent clinical efficacy against CCR4-positive T-cell lymphomas, especially against ATL. Among various toxicities associated with mogamulizumab, skin eruptions are the most significant. Although there are several effective competitors, mogamulizumab has a unique mechanism and is expected to be a key agent for treating CCR4-positive T-cell lymphomas, especially ATL.

    2011-01-01

    Full Text Available Hodgkin's lymphoma is a hematolymphoid neoplasm, primarily of B cell lineage, that has unique histologic, immunophenotypic, and clinical features. Neurologic complications of Hodgkin's Lymphoma can be separated into those that result directly from the disease, indirectly from the disease, or from its treatment. Direct neurologic dysfunction from Hodgkin's Lymphoma results from metastatic intracranial spinal disease, epidural metastases causing spinal cord/cauda equina compression, leptomeningeal metastases, or intradural intramedullary spinal cord metastases. Indirect neurologic dysfunction may be caused by paraneoplastic disorders (such as paraneoplastic cerebellar degeneration or limbic encephalitis and primary angiitis of the central nervous system. Hodgkin's lymphoma treatment typically includes chemotherapy or radiotherapy with potential treatment-related complications affecting the nervous system. Neurologic complications resulting from mantle-field radiotherapy include the “dropped head syndrome,” acute brachial plexopathy, and transient ischemic attacks/cerebral infarcts. Chemotherapy for Hodgkin's lymphoma may cause cerebral infarction (due to emboli from anthracycline-induced cardiomyopathy and peripheral neuropathy.

    1978-12-01

    The risk of cancer was ascertained in 136 women with sicca syndrome followed at the National Institutes of Health (NIH). Seven patients developed non-Hodgkin's lymphoma from 6 months to 13 years after their first admission to NIH. This was 43.8 times (P less than 0.01) the incidence expected from the rates of cancer prevailing among women of the same age range in the general population during this time. In addition, three cases of Waldenstroem's macroglobulinemia occurred in this study group. Eight patients developed cancers other than lymphoma, similar to the number expected based on the rates prevailing in the general population. Patients with a history of parotid enlargement, splenomegaly, and lymphadenopathy had an increased risk of lymphoma. These clinical conditions did not appear to be early manifestations of undiagnosed lymphoma but rather seemed to identify a subgroup of patients with sicca syndrome with marked lymphoid reactivity, who had a particularly high risk of subsequently developing lymphoma.

    Lymphoma is the most common haematopoietic malignancy in dogs, but little is known about the aetiology of this heterogeneous group of cancers. In humans, the Epstein-Barr virus (EBV) is associated with several lymphoma subtypes. Recently, it was suggested that EBV or an EBV-like virus is circulating in dogs. We therefore investigated whether EBV, or a novel herpesvirus, is associated with canine lymphoma using both serological and molecular techniques. In an assay designed to detect antibodies to EBV viral capsid antigens, 41 % of dogs were positive. Dogs with cancers, including lymphoma, were more frequently positive than controls, but no particular association with B-cell lymphoma was noted. EBV-specific RNA and DNA sequences were not detected in lymphoma tissue by in situ hybridization or PCR, and herpesvirus genomes were not detected using multiple degenerate PCR assays with the ability to detect novel herpesviruses. We therefore found no evidence that herpesviruses are directly involved in common types of canine lymphoma although cannot exclude the presence of an EBV-like virus in the canine population.

  20. Pembrolizumab in classical Hodgkin's lymphoma.

    Maly, Joseph; Alinari, Lapo

    2016-09-01

    Pembrolizumab is a humanized monoclonal antibody directed against programmed cell death protein 1 (PD-1), a key immune-inhibitory molecule expressed on T cells and implicated in CD4+ T-cell exhaustion and tumor immune-escape mechanisms. Classical Hodgkin's lymphoma (cHL) is a unique B-cell malignancy in the sense that malignant Reed-Sternberg (RS) cells represent a small percentage of cells within an extensive immune cell infiltrate. PD-1 ligands are upregulated on RS cells as a consequence of both chromosome 9p24.1 amplification and Epstein-Barr virus infection and by interacting with PD-1 promote an immune-suppressive effect. By augmenting antitumor immune response, pembrolizumab and nivolumab, another monoclonal antibody against PD-1, have shown significant activity in patients with relapsed/refractory cHL as well as an acceptable toxicity profile with immune-related adverse events that are generally manageable. In this review, we explore the rationale for targeting PD-1 in cHL, review the clinical trial results supporting the use of checkpoint inhibitors in this disease, and present future directions for investigation in which this approach may be used.

  4. Burkitt’s Lymphoma: Thorax to Pelvis.

    Science.gov (United States)

    2016-01-01

    Burkitt’s lymphoma is a sub-group of non-Hodgkin’s lymphoma of high-grade with an aggressive clinical course and is composed of diffuse, small and non-cleaved, undifferentiated malignant cells of lymphoid origin. Dennis Burkitt first described this entity in 1956 in equatorial Africa. It is one of the fastest growing cancers in humans with a growth fraction close to 100%. It commonly occurs in children and young adults, with frequent involvement of bone marrow and central nervous system. These are considered to be medical emergencies and require immediate diagnostic and therapeutic intervention. In this report, we present a case of Burkitt’s lymphoma with unusual presentation with the involvement of both thorax and the whole of the abdomen.

    Abstract Rationale: Plasmablastic lymphoma (PBL) is a rare subtype of human immunodeficiency virus (HIV)-related non-Hodgkin's lymphoma that predominantly manifests in the oral cavity. Patient concerns: Three cases of HIV-negative PBL were reported. Diagnoses: HIV-negative PBL Interventions: The patient had undergone chemotherapy. Outcomes: Clinical outcomes were very poor in Cases 1 and 3; Case 2, whose diagnosis suggested no bone marrow involvement, is still alive. Lessons subsections: These cases served to broaden the reported clinical spectrum of HIV-negative PBL. Clinicians and pathologists need to be familiar with lymphoma in the identified extra-oral PBL variation and there levant differential diagnosis procedures for this particular disease. PMID:28207555

    Full Text Available Context: The adrenal gland is a common site for neoplastic diseases and primary adrenal lymphoma (PAL is a rare tumor with around 120 cases reported so far. Case Report: We present a rare case of 76-year-old male who presented with headache, confusion, inappropriate body movements and abdominal pain. Adrenal biopsy revealed PAL and he has had an excellent neurologic outcome to date with chemotherapy and involved field radiation. Conclusion: The majority of cases of PAL are B cell lymphomas with diffuse large cell in 70% of cases. Clinical symptoms are variable and patients may present with abdominal pain, fever, anorexia, weight loss, fatigue or symptoms of adrenal insufficiency. Therapeutic modalities for PAL include surgery, chemotherapy and radiotherapy and corticosteroid replacement. With this case report, we hope to raise awareness about this rare disease and to include lymphoma in the differential of adrenal masses.

    Cutaneous lymphomas are uncommon in people and companion animals. The tumors can be broadly categorized into epitheliotropic and nonepitheliotropic forms, which appear to have different biological behaviors. The present case describes a feline cutaneous epitheliotropic lymphoma. Masses in a 9-year-old cat were first identified on the tail. The cat was treated with chemotherapy, but additional skin masses developed on the flank, face, and ears. Local radiation induced transient tumor regression, but eventual dissemination prompted euthanasia 13 months after initial tumor appearance. Granular lymphocytes were consistently detected on blood smears, and histologically, the tumor involved the skin and superficial subcutis. Tumor lymphocytes expressed cluster of differentiation 3 (CD3) and perforin molecules, suggestive of a cytotoxic phenotype. Location, histopathological features, and perforin expression were similar to a distinct entity in human medicine designated primary cutaneous, CD8-positive, epidermotropic, cytotoxic, T-cell lymphoma.

    Obinutuzumab is a humanized, type II anti-CD20 monoclonal antibody designed for strong induction of direct cell death and antibody-dependent cell-mediated cytotoxicity. The Phase III GADOLIN trial tested the clinical efficacy of obinutuzumab plus bendamustine followed by obinutuzumab monotherapy in rituximab-refractory indolent non-Hodgkin lymphoma versus treatment with bendamustine alone. It demonstrated significantly longer progression-free survival for the obinutuzumab-containing regimen in this difficult to treat patient group. Based on the results of this trial, US FDA approval was most recently granted for obinutuzumab in the treatment of follicular lymphoma that has relapsed after or was refractory to a rituximab-containing regimen. This article summarizes the available data on chemistry, pharmacokinetics, clinical efficacy and safety of obinutuzumab in the treatment of indolent non-Hodgkin lymphoma.

    Thirty-five cases of benign parapsoriasis en plaques, 24 cases of prereticulotic poikiloderma (3 of which were in evolution towards polymorphous lymphomas), 15 cases of lymphoma and 10 cases of other various skin proliferative disorders were studied. For various reasons the first two conditions are preferably indicated as type 1 and type 2 parapsoriasis. Attention is drawn to the possibility of finding a dermal fibro-histiocytary proliferative condition, more often in type 2 parapsoriasis than in type 1. Dysprotidemia, signs of a reactive bone marrow condition, and changes of the tryptophan leads to niacin pathway, as signs of various degrees of damage of connective tissue, were found in type 2 parapsoriasis and lymphomas.

    Primary central nervous system lymphoma (PCNSL) is a rare form of non-Hodgkin lymphoma that is limited to the CNS. Although novel imaging techniques aid in discriminating lymphoma from other brain tumors, definitive diagnosis requires brain biopsy, vitreoretinal biopsy, or cerebrospinal fluid analysis. Survival rates in clinical studies have improved over the past 20 years due to the addition of high-dose methotrexate-based chemotherapy regimens to whole-brain radiotherapy. Long-term survival, however, is complicated by clinically devastating delayed neurotoxicity. Newer regimens are attempting to reduce or eliminate radiotherapy from first-line treatment with chemotherapy dose intensification. Significant advances have also been made in the fields of pathobiology and treatment, with more targeted treatments on the horizon. The rarity of the disease makes conducting of prospective clinical trials challenging, requiring collaborative efforts between institutions. This review highlights recent advances in the biology, detection, and treatment of PCNSL in immunocompetent patients.

    2016-01-01

    Full Text Available Angioimmunoblastic T cell lymphoma (AITL is a rare but distinct type of T cell lymphoma with an aggressive course and high mortality. Most patients are diagnosed late in the disease and usually present with generalized lymphadenopathy. A minority have skin lesions at the time of diagnosis, more commonly in the form of nonspecific maculopapular rash with or without pruritus. We report a rare case of AITL presenting with chronic, recurrent angioedema and urticaria-like lesions and no palpable peripheral adenopathy. Primary Care physicians, dermatologists, and allergists must maintain a high index of suspicion for cutaneous manifestations of lymphoma, especially if the skin lesions are refractory to standard treatment. Timely diagnosis is essential to improve survival.

    Non-Hodgkin Lymphomas (NHL) represent a recent and fascinating domain of hemato-oncology, in which remarkable progress has been made. The conventional treatments of indolent lymphomas do not extend the survival rate, nor do they cure. Recent directions are centered on using several new drugs that are capable of overcoming the mechanisms that are resistant to recovery. The initiation of immunotherapy (Rituximab in 1997) seems to have changed the natural evolution of follicular lymphomas (FL). It is possible that resistance to healing in follicular lymphomas may be neutralized with Rituximab by suppressing STAT-1 positive macrophages that are present in the cellular microenvironment.Thereinafter, the re-evaluation of recent models of prognostic and therapeutic paradigmas that were used in FL became compulsory.The purpose of the paper is to compare the evolution of patients with follicular lymphoma and the period of response, according to the treatments. The study group consisted of the 71 patients diagnosed with follicular lymphoma, out of a total of 767 malignant lymphatic proliferations with B cells, for a period of 7 years (2002-2008), at the Hematology Department, Hospital Coltea, Bucharest and Hematology Department, Universitary Hospital, BucharestResults and conclusions: Combining chemotherapy with Rituximab had better results compared to the same chemotherapy, administered alone, both in induction and in case of relapse. The overall response rate in our study group was 74.7%, out of which 42.3% complete remissions. The overall response rate was 84.61% in the Rituximab group, compared to 68.88% in patients without Rituximab.

    Full Text Available Burkitt′s lymphoma is an uncommon form of non-Hodgkin lymphoma in adults. The diagnostic workup for Burkitt′s lymphoma includes radiological imaging and like any other form of non-Hodgkin′s lymphoma definitive diagnosis is by histopathology. Imaging is necessary to determine the distribution and severity in terms of extent and organs of involvement to further assist in staging and thence to implement appropriate therapy. High incidence of intraabdominal involvement is seen in American Burkitt lymphoma.

    Plasma cell dyscrasias are frequently associated with kidney disease through the production of monoclonal immunoglobulin but with a diverse set of pathologic renal patterns. While almost all patients with a renal biopsy showing a cast nephropathy have myeloma, kidney involvement associated with pathological immunoglobulin light chains and lymphoma is rare. To our knowledge, this is the first report of a cast nephropathy associated with lymphoplasmacytic lymphoma. We emphasize the relation between light chain deposition and renal dysfunction in this disease with production of light chains. A therapeutic approach that decreases light chain production appears to be warranted in these patients.

    2008-01-01

    Synopsis Diffuse Large B-Cell Lymphoma (DLBCL) remains a curable lymphoma, with improved outcome due in large part to incorporation of rituximab in standard regimens. The disease is heterogeneous clinically, morphologically, and molecularly. Recent insights into the molecular heterogeneity of DLBCL are beginning to yield novel therapeutics with significant promise for key subsets of patients. Although CHOP chemotherapy with rituximab remains a standard therapeutic approach for most patients with DLBCL, we anticipate that novel agents will be included in treatment regimens for many patients in the near future.

    Lymphoplasmacytoid lymphomas (LPL) are non-Hodgkin's lymphomas characterized by a proliferation of lymphoplasmacytoid cells or plasma cells with intracytoplasmic monoclonal Ig. The LPL are low-grade B-cell neoplasms close to B chronic lymphocytic leukemia with plasmacytoid differentiation. They show an indolent course, typically affect older men, and present as a disseminated disease with predominantly nodal involvement. Nevertheless, localized forms, some of them extranodal, have been described. The cases that best represent the range of radiographic findings on X-ray, CT, and MR imaging are presented. (orig.)

    Lymphoma is an uncommon tumor of bladder. We report herein one case in a 58 year-old man aiming to show diagnosis and treatment difficulties in our practice. This patient had medical history of nephritic colic, haematuria and cystitis. Imagery revealed tissular mass with orange-like dimension in the right bladder corn. There was no kidney function alteration. Complete mass excision was performed and histological examination diagnosed low grade lymphoma with lymphoplasmocytary type. After chemotherapy, complete remission was obtained after 10 months follow-up.

    In patients presenting with acute renal failure and known/suspected lymphoma, the diagnosis of diffuse renal involvement is important, as there is potential for rapid resolution with chemotherapy. Although FDG is excreted through the kidneys and focal renal disease may be difficult to identify, diffuse renal FDG is more easily recognized and is always abnormal. We report a patient presenting with acute renal failure and suspected lymphoma. F-18 FDG PET/CT study demonstrated diffuse increased FDG uptake in bilaterally enlarged kidneys. Following 1 cycle of chemotherapy, the renal function normalized. An interim F-18 FDG PET/CT demonstrated normal size and FDG uptake within both kidneys.

    Lymphoma (lymphosarcoma or malignant lymphoma) is the most common neoplasm of the hematopoietic system of cats and reportedly the cat has the highest incidence for lymphoma of any species. A 21-year retrospective survey of feline lymphoma covering the period 1983-2003 was conducted with the patient database at the Veterinary Medicine Teaching Hospital (VMTH) at the University of California, Davis, School of Veterinary Medicine. This period comprises the post-feline leukemia virus (FeLV) era. Feline lymphoma historically has been highly associated with retrovirus infection. Mass testing and elimination and quarantine programs beginning in the 1970s and vaccination programs in the 1980s dramatically reduced the subsequent FeLV infection rate among pet cats. The results of this survey confirm a significant decrease in the importance of FeLV-associated types of lymphoma in cats. In spite of this decrease in FeLV infection, the incidence of lymphoma in cats treated at the VMTH actually increased from 1982 to 2003. This increase was due largely to a rise in the incidence of intestinal lymphoma, and to a lesser degree, of atypical lymphoma. A high incidence of mediastinal lymphomas in young Siamese or Oriental breeds also was observed, supporting previous studies. Associations of intestinal lymphoma and inflammatory bowel disease and diet should be further considered.

  3. Cutaneous B cell lymphomas: Report of two interesting cases

    2015-01-01

    Full Text Available Cutaneous B cell lymphomas can arise primarily from the skin or may occur due to secondary spread from nodal lymphomas. Primary lymphomas are confined to the skin without systemic spread and they differ from secondary lymphomas in their clinical behavior, treatment and prognosis. Cutaneous lymphomas being relatively rare, lack of precise definition and understanding of their clinical behavior diseases leads to pitfalls in the diagnosis. We report two cases of cutaneous B cell lymphomas who presented with fever of unknown origin initially and later found to have skin lesions. Hence, skin can be a potential diagnostic clue in the evaluation of patients with fever of unknown origin. The distinctions between the primary and the secondary lymphomas become important in choosing the treatment and assessing the prognosis.

    2016-01-01

    Full Text Available We describe the case of a 13-year-old boy who presented with persistent thrombocytopenia during maintenance chemotherapy with mercaptopurine and methotrexate for T cell lymphoblastic lymphoma. He was diagnosed with immune thrombocytopenia (ITP after thorough investigations for the relapse of lymphoma and was successfully treated with immunoglobulin and steroids. ITP is known to be associated with chronic lymphocytic leukemia, Hodgkin lymphoma, and various types of non-Hodgkin lymphoma but rarely with T cell non-Hodgkin lymphoma or in children. Diagnosis of ITP with lymphoma is challenging due to the many factors affecting platelet counts, and ITP often complicates the diagnosis or treatment course of lymphoma. The underlying mechanism of ITP with NHL is still unclear. Drug-induced immunomodulation with a reduction of regulatory T cells might have contributed to the development of ITP in our case.

  5. Novel Therapies for Aggressive B-Cell Lymphoma

    Directory of Open Access Journals (Sweden)

    Kenneth A. Foon

    2012-01-01

    Full Text Available Aggressive B-cell lymphoma (BCL comprises a heterogeneous group of malignancies, including diffuse large B-cell lymphoma (DLBCL, Burkitt lymphoma, and mantle cell lymphoma (MCL. DLBCL, with its 3 subtypes, is the most common type of lymphoma. Advances in chemoimmunotherapy have substantially improved disease control. However, depending on the subtype, patients with DLBCL still exhibit substantially different survival rates. In MCL, a mature B-cell lymphoma, the addition of rituximab to conventional chemotherapy regimens has increased response rates, but not survival. Burkitt lymphoma, the most aggressive BCL, is characterized by a high proliferative index and requires more intensive chemotherapy regimens than DLBCL. Hence, there is a need for more effective therapies for all three diseases. Increased understanding of the molecular features of aggressive BCL has led to the development of a range of novel therapies, many of which target the tumor in a tailored manner and are summarized in this paper.

    Enteropathy associated T cell lymphoma is a rare primary intestinal lymphoma. It is often, but not always associated with celiac disease. Intraepithelial T cells are postulated as the cell of origin. It is a rare disease accounting for fewer than 5% of all gastrointestinal tract lymphomas. Recent studies indicate that EATL consists of two diseases that are morphologically and genetically distinct and differ with respect to their frequency of association with celiac disease. Current WHO classification recognises two subtypes of EATL – type 1 (classic) and type 2, based on morphology and immunophenotype. EATL type 1 is a large cell lymphoma which is more common and is more commonly associated with celiac disease compared to type 2. Most common site of involvement is the small intestine. We report a case of EATL type 1, in a 62-year-old female patient who presented with features of intestinal obstruction. However, she did not have spruce like featutes. PMID:25478355

    Full Text Available Introduction: Due to the high heterogeneity of canine lymphoma, the aim of the present study was to test in vitro the chemosensitivity of canine high-grade primary lymphoma cells to various cytostatic drugs commonly used to treat dogs: 4-HO-cyclophosphamide, doxorubicin, dexamethasone, prednisolone, vincristine, etoposide, chlorambucil, lomustine, and cytosine arabinoside. Material and Methods: To determine the cell viability and drug ability to induce apoptosis two different tests were used: an MTT assay and annexin V/propidium iodide staining. Results: Both in vitro tests were found to be useful tools. Significant differences in the sensitivity, depending on the drug type, between B-, T- and mixed/null-type lymphoma cells were found for the majority of the tested drugs. B-type cells were the most sensitive in vitro, whereas T-type cells seemed to be the most resistant. Doxorubicin, chlorambucil, etoposide, and vincristine most strongly reduced the cell viability and induced apoptosis. Conclusion: In vitro assays, such as the MTT test and especially the annexin V/PI assay, may be useful tools for predicting a response to the treatment of high-grade lymphoma in dogs or improving the treatment outcomes in individual animals.

    Full Text Available Introduction: Rhinoscleroma, a rare nasal granulomatous disease, is caused by Klebsiella rhinoscleromatis. The nose is the primary occurrence region. Nasal non-Hodgkin lymphoma is a rare cancer, and could be of T or B type. The rhinoscleroma and the nasal non-Hodgkin lymphoma present with nasal obstruction as the main symptom, and are part of the nasal granulomatosis differential diagnosis. Objective: To report the association of rhinoscleroma and non-Hodgkin lymphoma in the same patient, by remarking the importance of the nasal granulomatosis' differential diagnosis. Case Report: A forty-nine year old female patient that appeared with a one-month progressive nasal obstruction. Rhinoscopy showed papillomatous feature lesion in left middle meatus. The immunohistochemical analysis confirmed rhinoscleroma. The patient was duly treated with total remission of the lesion. Ten months after, she returned with the same symptoms, but the histologic study confirmed non-Hodgkin lymphoma. Final Comments: Both pathologies may cause more severe nasal symptoms and complications. The early diagnostic enables the choice for the right treatment and contributes for the prognosis. The immunohistochemical study was essential for the diagnostic differentiation.

    Full Text Available Abstract Background The most common cause of hypopituitarism is pituitary adenoma. However, in the case of suprasellar masses different etiologies are possible. We report an unusual case of primary suprasellar lymphoma presented with hypopituitarism. Case presentation A 26 year old woman presented with amenorrhea, galactorrhea and neurological disorders. Also, the laboratory work-up revealed partial hypopituitarism. The magnetic resonance imaging of the head showed a suprasellar mass. A presumptive diagnosis of granulomatous processes was made and the patient was given steroid therapy. Repeated brain MRI detected new lesions in the brain with regression of the suprasellar mass. Stereotactic biopsy of the paraventricular lesion revealed the diagnosis of B-cell lymphoma. Conclusion This case presentation reports a rare cause of hypopituitarism. Primary suprasellar lymphoma is extremely rare and represented a real diagnostic challenge. Besides, suprasellar masses are varied in aetiology and can present diagnostic problems for a radiologist. Also, because of the increased incidence of PCNSL, lymphoma must be kept in mind in the differential diagnosis of lesions in the suprasellar region.

    Standard methods for disease response assessment in patients with lymphoma, including positron emission tomography and computed tomography scans, are imperfect. In other hematologic malignancies, particularly leukemias, the ability to detect minimal residual disease (MRD) is increasingly influencing treatment paradigms. However, in many subtypes of lymphoma, the application of MRD assessment techniques, like flow cytometry or polymerase chain reaction-based methods, has been challenging because of the absence of readily detected circulating disease or canonic chromosomal translocations. Newer MRD detection methods that use next-generation sequencing have yielded promising results in a number of lymphoma subtypes, fueling the hope that MRD detection may soon be applicable in clinical practice for most patients with lymphoma. MRD assessment can provide real-time information about tumor burden and response to therapy, noninvasive genomic profiling, and monitoring of clonal dynamics, allowing for many possible applications that could significantly affect the care of patients with lymphoma. Further validation of MRD assessment methods, including the incorporation of MRD assessment into clinical trials in patients with lymphoma, will be critical to determine how best to deploy MRD testing in routine practice and whether MRD assessment can ultimately bring us closer to the goal of personalized lymphoma care. In this review article, we describe the methods available for detecting MRD in patients with lymphoma and their relative advantages and disadvantages. We discuss preliminary results supporting the potential applications for MRD testing in the care of patients with lymphoma and strategies for including MRD assessment in lymphoma clinical trials.

    New therapies are needed for patients with Hodgkin or non-Hodgkin lymphomas that are resistant to standard therapies. Indeed, unresponsiveness to standard chemotherapy and relapse after autologous stem-cell transplantation are indicators of an especially poor prognosis. Chimeric antigen receptor (CAR) T cells are emerging as a novel treatment modality for these patients. Clinical trial data have demonstrated the potent activity of anti-CD19 CAR T cells against multiple subtypes of B-cell lymphoma, including diffuse large-B-cell lymphoma (DLBCL), follicular lymphoma, mantle-cell lymphoma, and marginal-zone lymphoma. Importantly, anti-CD19 CAR T cells have impressive activity against chemotherapy-refractory lymphoma, inducing durable complete remissions lasting >2 years in some patients with refractory DLBCL. CAR-T-cell therapies are, however, associated with potentially fatal toxicities, including cytokine-release syndrome and neurological toxicities. CAR T cells with novel target antigens, including CD20, CD22, and κ-light chain for B-cell lymphomas, and CD30 for Hodgkin and T-cell lymphomas, are currently being investigated in clinical trials. Centrally manufactured CAR T cells are also being tested in industry-sponsored multicentre clinical trials, and will probably soon become a standard therapy. Herein, we review the clinical efficacy and toxicity of CAR-T-cell therapies for lymphoma, and discuss their limitations and future directions with regard to toxicity management, CAR designs and CAR-T-cell phenotypes, conditioning regimens, and combination therapies.

    Mucosa-associated lymphoid tissue (MALT) lymphoma originated outside the lymph nodes is low grade malignant B cell lymphoma. It is the most frequent type of marginal zone non-Hodgkin's lymphoma, that usually occurs in the stomach, salivary gland, thyroid gland and orbital adnexa. Gastric MALT lymphoma accounts for 50% of MALT lymphoma. Gastric MALT lymphoma has been confirmed to relate with Helicobacter pylori (HP) infection, its main pathogenesis is immune reaction, but some patients with chromosome translocation have no response to HP eradication, suggesting presence of other unknown pathogenesis. The chromosome translocations in MALT lymphoma are t(11;18)(q21;q21), t(1;14)(p22;q32), t(14;18)(q32;q21), t(3;14)(p14.1;q32). Recent studies show some new chromosomal abnormalities such as 6q23.3/A20 and so on, which have some effects on clinical course and prognosis. MALT lymphoma with chromosome abnormalities usually activate common NF-κB molecular pathway, and persistent active NF-κB pathway drives tumor cell proliferative and active, resulting in lymphoma incidence. In this article, the advances in the etiology and pathogenesis of MALT lymphoma were reviewed.

    Nodular lymphocyte predominant Hodgkin lymphoma represents a distinct entity from classical Hodgkin lymphoma. We conducted a retrospective study to investigate the management of patients with nodular lymphocyte predominant Hodgkin lymphoma. Clinical characteristics, treatment and outcome of adult patients with nodular lymphocyte predominant Hodgkin lymphoma were collected in Lymphoma Study Association centers. Progression-free survival (PFS) and overall survival (OS) were analyzed, and the competing risks formulation of a Cox regression model was used to control the effect of risk factors on relapse or death as competing events. Among 314 evaluable patients, 82.5% had early stage nodular lymphocyte predominant Hodgkin lymphoma. Initial management consisted in watchful waiting (36.3%), radiotherapy (20.1%), rituximab (8.9%), chemotherapy or immuno-chemotherapy (21.7%), combined modality treatment (12.7%), or radiotherapy plus rituximab (0.3%). With a median follow-up of 55.8 months, the 10-year PFS and OS estimates were 44.2% and 94.9%, respectively. The 4-year PFS estimates were 79.6% after radiotherapy, 77.0% after rituximab alone, 78.8% after chemotherapy or immuno-chemotherapy, and 93.9% after combined modality treatment. For the whole population, early treatment with chemotherapy or radiotherapy, but not rituximab alone (Hazard ratio 0.695 [0.320–1.512], P=0.3593) significantly reduced the risk of progression compared to watchful waiting (HR 0.388 [0.234–0.643], P=0.0002). Early treatment appears more beneficial compared to watchful waiting in terms of progression-free survival, but has no impact on overall survival. Radiotherapy in selected early stage nodular lymphocyte predominant Hodgkin lymphoma, and combined modality treatment, chemotherapy or immuno-chemotherapy for other patients, are the main options to treat adult patients with a curative intent.

    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. Isolated paracortical expantion, compartmentalization of neoplastic infiltrate and large atypical Reed-Stemberg-like cells were occasional findings. 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.

    Gastric mucosa associated lymphoid tissue (MALT)lymphoma has recently been incorporated into the World Health Organization (WHO) lymphoma classification,termed as extranodal marginal zone B-cell lymphoma of MALT-type. In about 90% of cases this lymphoma is associated with H pylori infection which has been clearly shown to play a causative role in lymphomagenesis.Although much knowledge has been gained in defining the clinical features, natural history, pathology, and molecular genetics of the disease in the last decade, the optimal treatment approach for gastric MALT lymphomas,especially locally advanced cases, is still evolving. In this review we focus on data for the therapeutic, stage dependent management of gastric MALT lymphoma.Hence, the role of eradication therapy, surgery,chemotherapy and radiotherapy is critically analyzed.Based on these data, we suggest a therapeutic algorithm that might help to better stratify patients for optimal treatment success.

    2010-06-01

    We present a follow-up case report of possible transmission of lymphoma 12 years after deceased-donor renal transplantation from a male donor who was found at autopsy to have had an occult lymphoma. The female recipient underwent prompt transplant nephrectomy. However, 12 years later, she presented with cerebral B cell lymphoma. A donor origin for the cerebral lymphoma was supported by in situ hybridization demonstration of a Y chromosome in the lymphoma. There was a dramatic resolution of the cerebral lesions with tapering of immunosuppression and introduction of rituximab treatment. The finding of a Y chromosome in the cerebral lymphoma does not exclude a host contribution to lymphoma development.

    Full Text Available Chylothorax is caused by disruption or obstruction of the thoracic duct or its tributaries that results in the leakage of chyle into the pleural space. A number of interventions have been used to treat chylothorax including the treatment of the underlying disease. Lymphoma is found in 70% of cases with nontraumatic malignant aetiology. Although patients usually have advanced lymphoma, supradiaphragmatic disease is not always present. We discuss the case of a 63-year-old woman presenting with progressive respiratory symptoms due to chylothorax. She was diagnosed with a stage IIE retroperitoneal grade 1 follicular lymphoma extending from the coeliac trunk towards the pelvic inlet. Despite thoracocentesis and medium-chain triglycerides (MCT, diet chylothorax reoccurred. After low dose radiotherapy (2×2 Gy to the abdominal lymphoma there was a marked decrease in lymphadenopathy at the coeliac trunk and a complete regression of the pleural fluid. In this case, radiotherapy was shown to be an effective nontoxic treatment option for lymphoma-associated chylothorax with long-term remission of pleural effusion.

    Full Text Available Primary mediastinal B-cell lymphoma (PMBCL is an uncommon aggressive subset of diffuse large B-cell lymphomas. Although PMBCL frequently spreads locally from the thymus into the pleura or pericardium, it rarely invades directly through the heart. Herein, we report a case of a young Mexican female diagnosed with PMBCL with clear infiltration of lymphoma through the cardiac wall and into the right atrium and tricuspid valve leading to tricuspid regurgitation. This was demonstrated by cardiac MRI and transthoracic echocardiogram. In addition, cardiac MRI and CT scan of the chest revealed the large mediastinal mass completely surrounding and eroding into the superior vena cava (SVC wall causing a collar of stokes. The cardiac and SVC infiltration created a significant therapeutic challenge as lymphomas are very responsive to chemotherapy, and treatment could potentially lead to vascular wall rupture and hemorrhage. Despite the lack of conclusive data on chemotherapy-induced hemodynamic compromise in such scenarios, her progressive severe SVC syndrome and respiratory distress necessitated urgent intervention. In addition to the unique presentation of this rare lymphoma, our case report highlights the safety of R-CHOP treatment.

    Radiotherapy plays an important role in the treatment of cutaneous lymphomas. In the treatment of Mycosis fungoides, total skin electron beam radiation therapy is efficient for patients with limited and superficial forms of the disease. Radiotherapy is also efficient for the locally advanced forms of non-epidermo-tropic lymphomas. The palliative radiotherapy is indicated for advanced, nodular and treatment resistant forms of cutaneous lymphomas and for voluminous lymphadenopathies. (authors)

    Primary cutaneous lymphomas are a heterogeneous group of diseases. They often remain localized, and they generally have a more indolent course and a better prognosis than lymphomas in other locations. They are highly radiosensitive, and radiation therapy is an important part of the treatment, either as the sole treatment or as part of a multimodality approach. Radiation therapy of primary cutaneous lymphomas requires the use of special techniques that form the focus of these guidelines. The International Lymphoma Radiation Oncology Group has developed these guidelines after multinational meetings and analysis of available evidence. The guidelines represent an agreed consensus view of the International Lymphoma Radiation Oncology Group steering committee on the use of radiation therapy in primary cutaneous lymphomas in the modern era.

    Full Text Available A 65-year-old gentleman presented with left groin swelling over the course of two months. Physical exam revealed nontender left inguinal adenopathy, and computed tomography scans detected multiple lymph nodes in the mesenteric, aortocaval, and right common iliac regions. An excisional lymph node biopsy was performed. Pathologic evaluation demonstrated follicular center site which stained positive for PAX5, CD20, CD10, Bcl-2, Bcl-6, and mantle zone cells. These findings demonstrated CCND1 and CD5 positivity, suggesting composite lymphoma comprising follicular lymphoma (FL with in situ mantle cell lymphoma (MCLIS. FL is known as indolent non-Hodgkin lymphoma; however, the clinical significance of a coexisting MCLIS continues to be elusive, and optimal management of these patients remains largely unknown. This case illustrates the diagnostic and therapeutic challenges of composite lymphomas. This paper also discusses advances in molecular pathogenesis and lymphoma genomics which offer novel insights into these rare diseases.

    Acute pancreatitis is a rare initial presentation of non-Hodgkin lymphoma with few reported cases described in older adults and even fewer in children. MRI features of Burkitt lymphoma of the pancreas are sparse in the radiologic literature. We present a 6-year-old boy who presented with pancreatitis and obstructive jaundice, which was the result of Burkitt lymphoma of the pancreas. The imaging findings of pancreatic involvement of Burkitt lymphoma on MRI are discussed and the contributory role of the radiologist in guiding the appropriate clinical work-up of this disease is highlighted.

    Isolated primary malignant lymphoma rarely arises from the anterior visual pathway. A 59-year-old previously healthy man presented with progressive, painless, bilateral visual disturbance. Neurological imaging revealed an enhancing mass arising from the optic chiasm. Open biopsy was carried out under monitoring of visual evoked potentials and a histopathological diagnosis of diffuse large B-cell lymphoma was made. As systemic examination did not show any evidence of systemic lymphoma, we concluded that this patient had an isolated primary malignant lymphoma at the anterior visual pathway.

    Full Text Available Primary gastrointestinal T-cell lymphoma is an uncommon entity and primary colon T-cell lymphoma is even rarer. The majority of enteropathy-associated T-cell lymphomas present predominantly as ulcers or strictures in the endoscopic examinations, while primary B-cell lymphomas commonly present as exophytic lesions. Ulcerative colon T-cell lymphoma may mimic Crohn's disease (CD, which is a chronic inflammatory disease of the intestines with ulcer and fistula formations difficult for clinicians to diagnose based on endoscopic observations alone. Like CD, T-cell lymphoma may be characterized by the presence of multiple skipped ulcers distributed from the terminal ileum to the descending colon. Furthermore, it is difficult to diagnose this unusual lymphoma by a single endoscopic biopsy. Typically, the histological composition of T-cell lymphoma is made of medium to large atypical cells located in the base of the ulcer with extension to the muscle layer and the adjacent mucosa. However, it is common that biopsy specimens show only mixed inflammatory changes where the lymphoma cells are hard to be identified. The differential diagnosis of malignant lymphoma must be considered when clinically diagnosed CD is refractory to the medical treatment or when its clinical behavior becomes aggressive. The current study presents a rare case of primary colon T-cell lymphoma in a 56-year-old male with marked recent weight loss, watery diarrhea and bilateral neck lymphadenopathy, who received a laboratory checkup and endoscopic workup for colon biopsy. The initial pathological report was consistent with mucosal inflammation and benign colon ulcers. Interestingly, the blood test showed a prominent eosinophilia. A biopsy of the enlarged neck lymph nodes done approximately 1 month after the colon biopsy unexpectedly showed T-cell lymphoma, which led to a review of the initial colonic biopsy specimens. Additional immunohistochemical stains were used accordingly, which

    Full Text Available Follicular lymphoma (FL is an indolent lymphoma with long median survival. Many studies have been performed to build up prognostic scores potentially useful to identify patients with poorer outcome. In 2004, an international consortium coordinated by the International Follicular Lymphoma Prognostic Factor project was established and a new prognostic study was launched (FLIPI2 using progression-free survival (PFS as main endpoint and integrating all the modern parameters prospectively collected. Low-grade non-Hodgkin lymphomas were once considered as a heterogenous group of lymphomas characterized by an indolent clinical course. Each entity is characterized by unique clinicobiologic features. Some studies have been focused on prognostic factors in single lymphoma subtypes, with the development of specific-entity scores based on retrospective series, for instance splenic marginal zone lymphoma (SMZL. A widely accepted prognostic tool for clinical usage for indolent non-follicular B-cell lymphomas is largely awaited. In this paper we summarized the current evidence regarding prognostic assessment of indolent follicular and non-follicular lymphomas.

    Yadlapati, Sujani; Efthimiou, Petros

    2016-01-01

    Specific autoimmune and inflammatory rheumatic diseases have been associated with an increased risk of malignant lymphomas. Conditions such as rheumatoid arthritis (RA), primary Sjögren's syndrome (pSS), systemic lupus erythematosus (SLE), dermatomyositis, and celiac disease have been consistently linked to malignant lymphomas. Isolated cases of lymphomas associated with spondyloarthropathies and autoinflammatory diseases have also been reported. Direct association between autoimmunity and lymphomagenesis has been reinforced by large epidemiological studies. It is still uncertain whether disease specific determinants or phenotypic or treatment related characteristics increase likelihood of lymphomagenesis in these patients. For example, recent literature has indicated a positive correlation between severity of inflammation and risk of lymphomas among RA and Sjögren's syndrome patients. It is also debated whether specific lymphoma variants are more commonly seen in accordance with certain chronic autoimmune arthritis. Previous studies have revealed a higher incidence of diffuse large B-cell lymphomas in RA and SLE patients, whereas pSS has been linked with increased risk of mucosa-associated lymphoid tissue lymphoma. This review summarizes recent literature evaluating risk of lymphomas in arthritis patients and disease specific risk determinants. We also elaborate on the association of autoimmune arthritis with specific lymphoma variants along with genetic, environmental, and therapeutic risk factors.

    Non-Hodgkin's lymphoma (NHL) is the third common malignant lesion of the oral region. Plasmablastic lymphomas are rare, aggressive neoplasms occurring mostly in human immunodeficiency virus (HIV) infected individual which accounts for approximately 2.6% of all NHL. It usually presents as a diffuse growth and with diffuse pattern of histological presentation. It is very difficult to differentiate this lymphoma from other NHL. Immunohistochemical evaluation of various markers is an important criteria of the diagnostic protocol. Here, we describe a case of plasmablastic lymphoma in a 50-year-old female HIV-infected patient. The diagnosis was based on histopathological examination and immunophenotyping. PMID:27795651

    The aim of this review is to give an overview of FDG PET/CT applications in children and adolescents with lymphoma. Today, FDG PET is used for tailoring treatment intensity in children with Hodgkin lymphoma within the framework of international treatment optimisation protocols. In contrast, the role of this method in children with Non-Hodgkin lymphoma is not well defined. This paper overviews clinical appearance and metabolic behaviour of the most frequent lymphoma subtypes in childhood. The main focus of the review is to summarise knowledge about the role of FDG PET/CT for initial staging and early response assessment. (orig.)

    Lymphomas comprise a variety of entities with remarkable clinical heterogeneity. This review summarizes the current knowledge on the pathogenesis of major mature B-cell lymphoma subtypes for clinicians working outside the field of hemato-oncology. The understanding of the pathogenesis of lymphomas is linked to the knowledge on normal B-cell differentiation. The clinical diversity is manifested in the different mechanisms involved in lymphomagenesis that include characteristic chromosomal translocations deregulating proto-oncogenes, and inactivation of tumor suppressor genes through deletions and mutations. Gene-expression profiling has dissected certain lymphomas into morphologically indistinguishable, but clinically important subgroups and uncovered pathways suitable for specific therapeutic interventions.

    Mantle cell lymphoma (MCL) is a rare and aggressive subtype of non-Hodgkin lymphoma. New treatment modalities, including intensive induction regimens with immunochemotherapy and autologous stem cell transplant, have improved survival. However, many patients still relapse, and there is a need...... for novel therapeutic strategies. Recent progress has been made in the understanding of the role of microRNAs (miRNAs) in MCL. Comparisons of tumor samples from patients with MCL with their normal counterparts (naive B-cells) have identified differentially expressed miRNAs with roles in cellular growth...... and survival pathways, as demonstrated in various biological model systems. In addition, MCL clinico-pathological and prognostic subtypes can be identified using individual miRNAs or miRNA classifiers. miRNA based therapies have now shown efficacy in animal models, and many efforts are currently being made...

    2013-09-01

    Full Text Available Purpose: To describe the case of a patient affected by orbital lymphoma mimicking pleomorphic adenoma of the lacrimal gland. Methods: This was a retrospective case report. Results: We present the case of a patient with 15-year history of slowly progressive left proptosis and inferomedial bulbar dislocation who had the presumptive diagnosis of lacrimal gland pleomorphic adenoma based on clinical and radiological features. The patient underwent lateral orbitotomy and lacrimal gland excision. Postoperative histological features were consistent with low-grade B-cell non-Hodgkin lymphoma. Conclusion: The accepted clinico-radiological criteria used for the diagnosis of lacrimal gland fossa lesions might have a certain false-positive rate, even in recent years. The initial surgical approach with the appropriate choice between fine-needle aspiration biopsies, intraoperative biopsies and lacrimal gland excisions might be a challenge.

    Double hit lymphomas (DHLs) are a new category in the World Health Organization newest classification for lymphoid malignancies. DHL encompasses various histologies of lymphomas where the MYC oncogene and either BCL2 or BCL6 oncogenes are present concomitantly. Several observational studies and retrospective series have demonstrated that patients with DHL carry a poor prognosis and respond less and for a shorter duration to standard R-CHOP (rituximab, cyclophosphamide, vincristine, adriamycin, and prednisone). These studies have also proposed that dose intensification (with Burkitt-like regimens such as DA-EPOCH-R [dose-adjusted rituximab, etoposide, vincristine, Adriamycin, cyclophosphamide, and prednisone]) might offer patients with DHL better outcomes and improved prognosis. In this timely review, we discuss incidence of DHL, testing implications of MYC translocation, current treatment strategies, and future directions. Understanding this entity and its therapeutic consequences is essential to improve patients' outcomes. Copyright © 2017 Elsevier Inc. All rights reserved.

    A 43-year-old woman presented with a salmon-coloured patch of 0.7mm diameter in the right eye that extended into the lower fornix in the bulbar and tarsal conjunctiva, with irregular edges, and highly vascularised. Incisional biopsy was performed, showing it to be a low-grade conjunctival non-Hodgkin B cell lymphoma (or a mucosa associated lymphoid tissue [MALT] lymphoma). The lesion remained stable for 24 months of follow-up, when a relapse of the condition occurred, producing an enlargement of the initial lesion. The definitive diagnosis is made by biopsy of the affected tissue and histopathologic study. Copyright © 2016 Sociedad Española de Oftalmología. Publicado por Elsevier España, S.L.U.

    Full Text Available Hepatitis C virus (HCV is a positive, single-stranded RNA virus, which has been associated to different subtypes of B-cell non-Hodgkin lymphoma (B-NHL. Cumulative evidence suggests an HCV-related antigen driven process in the B-NHL development. The underlying molecular signature associated to HCV-related B-NHL has to date remained obscure. In this review, we discuss the recent developments in this field with a special mention to different sets of genes whose expression is associated with BCR coupled to Blys signaling which in turn was found to be linked to B-cell maturation stages and NF-κb transcription factor. Even if recent progress on HCV-B-NHL signature has been made, the precise relationship between HCV and lymphoma development and phenotype signature remain to be clarified.

  7. Dual diagnosis of sarcoidosis and lymphoma.

    LENUS (Irish Health Repository)

    2013-06-01

    Sarcoidosis is a multisystem granulomatous disease of unknown origin with pulmonary and extrapulmonary manifestations. Worldwide it is most often diagnosed in the third and fourth decades and most often affects Swedish, Danish and black patients. The association between malignancy and sarcoidosis has not been conclusively proven. Cancer can eventually occur in patients who have an established diagnosis of sarcoidosis for example, in sarcoidosis-lymphoma syndrome. Sarcoidosis can also subsequently develop in an oncology patient. There are multiple obstacles to confirming epidemiologically the linkage between sarcoidosis and malignancy. Histological verification and clinical acumen are needed to avoid misdiagnosis. The 18 fluorodeoxyglucose (18-FDG) PET has failed to provide a non invasive diagnostic method to differentiate neoplasia from benign sarcoid lesions and tissue diagnosis is essential before commencing a new therapeutic intervention in patients with lymphoma.

    Follicular lymphoma (FL) is an indolent disease but transforms in 2% to 3% of patients per year into aggressive, large cell lymphoma, a critical event in the course of the disease associated with increased lymphoma-related mortality. Early transformation cannot be accurately predicted at the time of FL diagnosis and the biology of transformed FL (TFL) is poorly understood. Here, we assembled a cohort of 126 diagnostic FL specimens including 40 patients experiencing transformation (transformation for at least 5 years. In addition, we assembled an overlapping cohort of 155 TFL patients, including 114 cases for which paired samples were available, and assessed temporal changes of routinely available biomarkers, outcome after transformation, as well as molecular subtypes of TFL. We report that the expression of IRF4 is an independent predictor of early transformation (Hazard ratio, 13.3; P transformation predicts favorable prognosis. Moreover, applying the Lymph2Cx digital gene expression assay for diffuse large B-cell lymphoma (DLBCL) cell-of-origin determination to 110 patients with DLBCL-like TFL, we demonstrate that TFL is of the germinal-center B-cell-like subtype in the majority of cases (80%) but that a significant proportion of cases is of the activated B-cell-like (ABC) subtype (16%). These latter cases are commonly negative for BCL2 translocation and arise preferentially from BCL2 translocation-negative and/or IRF4-expressing FLs. Our study demonstrates the existence of molecular heterogeneity in TFL as well as its relationship to the antecedent FL.

    Full Text Available The incidence of primary gastric lymphoma in Italy is considerably higher than that observed in the rest of Europe. It is widely accepted that gastric B-cell, low-grade mucosalassociated lymphoid tissue (MALT lymphoma is caused by specific host-bacterial interactions that occur during Helicobacter pylori infection. This review examines recent findings on the origins, diagnosis, treatment, and follow-up of gastric MALT lymphomas. Clinical and endoscopic findings at diagnosis vary widely. In a substantial number of cases, the patient presents only vague dyspeptic symptoms or poorly defined abdominal pain with no macroscopic lesions on the gastric mucosa. Review of data from 32 trials in which a total of 1,387 MALT-lymphoma patients of the stomach were treated solely with H. pylori eradication revealed high remission rates when the disease is treated early (stage I-II1. Neoplasia confined to the submucosa, antral localization of tumors, and negativity for the API2-MALT1 translocation were associated with a high probability of remission following H. pylori eradication. When the latter approach is not sufficient, radiotherapy, chemotherapy and, in selected cases, surgery are associated with high success rates; data on the efficacy of monoclonal antibody therapy (rituximab are still limited. Five-year survival rates are higher than 90%. Patients whose tumors have been eliminated require close, long-term endoscopic follow-up since recurrence has been reported in some cases. Broader clinical follow-up is also advisable because the incidence of other solid tumors and of cardiovascular events is reportedly increased in these patients.

    Full Text Available Enteropathy associated T-cell lymphoma (EATCL is a high grade, pleomorphic peripheral T-cell lymphoma with usually cytotoxic phenotype. This is a case report of three patients with EATCL. The first patient was 50 year-old woman with four year history of gluten sensitive enteropathy (GSE. Diagnosis of lymphoma was confirmed after the resection of the jejunum (small intestine obstruction. Pathohistological (PAS, Reticulin, Giemsa and immunohistochemical (anti-LCA, anti-CD20, anti- CD45RO, anti-CD3 methods revealed the diagnosis of EATCL: CD45RO+, CD3+. After the third cycle of chemotherapy, the disease progressed with massive lung infiltration. Patient died due to complications of bone marrow aplasia. The second patient was 23 year-old woman with long earlier history of GSE. She presented with the acute renal failure. According to established diagnosis of tubulointerstitial nephritis, she was treated with pulse doses of steroid therapy. After temporary improvement, she had dissemination of the disease. On MRI, small intestinal wall was thickened, and abdominal lymph nodes were enlarged with extraluminal compression of common bile duct. Laparotomy with mesenterial lymph node biopsy and consecutive pathohistological and immunohistochemical analyses revealed the diagnosis of EATCL. The patient received chemotherapy, but she died with signs of pulmonary embolization. The third patient was 53 year-old woman without previous history of GSE. Diagnosis of EATCL was revealed after the resection of jejunum because of small intestinal obstruction. She received two cycles of chemotherapy, but she died with signs of disease progression. IgA antiendomysial antibodies were detected in the serum of all patients. The overall survival of patients was 7 months. The possibility of lymphoma rising in patients with clinical progression of GSE despite gluten free diet must be kept in mind.

    Nodal marginal zone lymphoma (NMZL) is a rare, indolent B-cell tumor that is distinguished from splenic marginal zone lymphoma (SMZL) by the different pattern of dissemination. NMZL still lacks distinct markers and remains orphan of specific cancer gene lesions. By combining whole-exome sequencing, targeted sequencing of tumor-related genes, whole-transcriptome sequencing, and high-resolution single nucleotide polymorphism array analysis, we aimed at disclosing the pathways that are molecularly deregulated in NMZL and we compare the molecular profile of NMZL with that of SMZL. These analyses identified a distinctive pattern of nonsilent somatic lesions in NMZL. In 35 NMZL patients, 41 genes were found recurrently affected in ≥3 (9%) cases, including highly prevalent molecular lesions of MLL2 (also known as KMT2D; 34%), PTPRD (20%), NOTCH2 (20%), and KLF2 (17%). Mutations of PTPRD, a receptor-type protein tyrosine phosphatase regulating cell growth, were enriched in NMZL across mature B-cell tumors, functionally caused the loss of the phosphatase activity of PTPRD, and were associated with cell-cycle transcriptional program deregulation and increased proliferation index in NMZL. Although NMZL shared with SMZL a common mutation profile, NMZL harbored PTPRD lesions that were otherwise absent in SMZL. Collectively, these findings provide new insights into the genetics of NMZL, identify PTPRD lesions as a novel marker for this lymphoma across mature B-cell tumors, and support the distinction of NMZL as an independent clinicopathologic entity within the current lymphoma classification. © 2016 by The American Society of Hematology.

    Full Text Available The morphometry in histopathology is used to characterize cell populations belonging to different tissues and to identify differences in their parameters with prognostic implications. To achieve morphometric examination were selected 6 of 24 cases identified as small cell lymphocytic lymphoma. For each case analysis was done on five fields, for each field measuring the parameters of 20 cells. The studied parameters were for cytoplasm: cytoplasmic area, maximum and minimum cytoplasmic diameter, cytoplasmic perimeter; for nucleus were measured: nuclear area, minimum and maximum nuclear diameter, nuclear perimeter, nuclear contour index, nuclear ellipticity index, nuclear irregularity index. Also the nucleocytoplasmic ratio was calculated in all studied cases. Small cell lymphocytic lymphoma is characterized in morphometric terms having a small cytoplasmic area (average 29.206 and also a small nuclear area (mean 28.939 having a nucleo-cytoplasmic ratio appearance suggestive for adult lymphocyte. A nuclear contour index small value (3.946, ellipticity index value also small (3.521 and small nuclear irregularity index (3.965. Standard deviations, in any of the studied morphometric categories, is around or below 1 suggesting monomorphic cell appearance. These morphometric and microscopic features characterized mainly by a small population of adult lymphocytes, monomorphic, with rounded hipercromic nuclei, dense chromatin, support the framing into indolent lymphoma group in terms of clinical outcome.

    In 1832, Dr. Thomas Hodgkin reported the first cases with this malignancy, which came to be named Hodgkin's disease. The cells that are a hallmark of this disease, Hodgkin and Reed-Sternberg (HRS) cells, account for only 1% of those in tumor tissues, with the majority of cells in Hodgkin lymphoma being of various inflammatory types. Advances in molecular techniques have contributed to molecular biological analysis of HRS cells. Intriguingly, HRS cells are derived from germinal center B-cells, but have lost their B-cell gene-expression and co-express non-B-cell genes. Multiple signaling pathways, including the NFκB and JAK/STAT pathways, show deregulated activity in HRS cells, suggesting an important role for these pathways in the pathogenesis of Hodgkin lymphoma. This article describes the molecular pathological characteristics of HRS cells: 1) the cellular origin of HRS cells, 2) deregulated gene expression in HRS cells, 3) genetic alterations and 4) epigenetic alterations in HRS cells, 5) the lost B-cell phenotype of HRS cells, 6) the role of EBV in Hodgkin lymphoma pathogenesis, and 7) micro-environmental interactions between HRS and reactive cells.

    The authors report a case of urogenital lymphoma with multiple sites in a patient presenting with oligo-anuria. Clinical examination revealed a hard hypogastric and prostatic mass and an enlarged left scrotum. Abdominopelvic and scrotal ultrasound demonstrated a prostatic tumour, a hypogastric mass, hepatic nodular lesions and coeliac lymphadenopathy with bilateral ureterohydronephrosis and a heterogeneous intrascrotal mass in contact with the lower pole of the left testis. The laboratory assessment revealed severe renal failure. After a haemodialysis session and ultrasound-guided right percutaneous nephrostomy, pelvic magnetic resonance imaging (MRI) showed a very large pelvic mass between the bladder and the rectum and transrectal biopsy of the mass confirmed the diagnosis of high-grade malignant non-Hodgkin's lymphoma (NHL) with a type B lymphoblastic phenotype. Treatment consisted of chemotherapy according to the LMB 93 protocol. The course was favourable with return of normal renal function and complete remission 1 month after induction. The patient is currently in complete remission with a follow-up of 12 months. In the light of this case and a review of the literature, the authors discuss the diagnostic, therapeutic and prognostic aspects of this rare site of lymphoma.

    Full Text Available Diffuse large B-cell lymphoma (DLBCL is the most common type of non-Hodgkin lymphoma (NHL, representing approximately 25% of diagnosed NHL. DLBCL is heterogeneous disease both clinically and genetically. The 3 most common chromosomal translocations in DLBCL involve the oncogenes BCL2, BCL6, and MYC. Double hit (DH DLBCL is an aggressive form in which MYC rearrangement is associated with either BCL2 or BCL6 rearrangement. Patients typically present with a rapidly growing mass, often with B symptoms. Extranodal disease is often present. Though there is a paucity of prospective trials in this subtype, double hit lymphoma (DHL has been linked to very poor outcomes when patients are treated with standard R-CHOP. There is, therefore, a lack of consensus regarding the standard treatment for DHL. Several retrospective analyses have been conducted to help guide treatment of this disease. These suggest that DA EPOCH-R may be the most promising regimen and that achievement of complete resolution predicts better long-term outcomes.

    In 1997, the approval of the anti-CD20 antibody rituximab heralded a new era of combined immunochemotherapy for the treatment of malignant lymphoma. Until then, a combination of cyclophosphamide, vincristine, doxorubicin, and prednisone (CHOP) had been the standard of treatment for aggressive B-cell lymphoma for more than 25 years. The addition of rituximab led to an impressive improvement of response rates and survival outcomes in patients with follicular and diffuse large B-cell lymphoma (DLBCL) that has been confirmed in several randomized trials. Remaining challenges in the rituximab era are the identification of the optimal chemotherapy partner with respect to synergistic effects, as well as to the lack of interference with its effector mechanisms. Finally, the question of the optimal dosage and schedule of rituximab has to be addressed in well-designed randomized trials. The outcome of patients relapsing after a rituximab-containing induction regimen is dismal even with high-dose therapy and autologous stem cell transplantation (ASCT). For these patients new modalities of second-line therapy are urgently warranted.

    Full Text Available Follicular lymphoma (FL is the most common indolent non-Hodgkin lymphoma, typically affected mature adults and elderly, with a median age at diagnosis of 65 years. The natural history of FL appears to have been favorably impacted by the introduction of Rituximab. Randomized clinical trials have demonstrated that the addition of rituximab to standard chemotherapy induction has improved the overall survival and new strategies of chemo-immunotherapy, such as Bendamustine combined with Rituximab, showed optimal results on response and lower hematological toxicity, becoming one of the standard treatments, particularly in elderly. Moreover maintenance therapy with Rituximab demonstrated improvement of progression-free survival. Despite these exciting results, FL is still an incurable disease. It remains a critical unmet clinical need finding new prognostic factors to better identify poor outcome patients, to reduce the risk of transformation and to explore new treatment strategies, especially for patients not candidate to intensive chemotherapy regimens, such as elderly patients. Some progresses were already done with novel agents, but larger and more validated studies are needed. Elderly patients are the larger portion of patients with FL and represent a subgroup with higher treatment difficulties, because of comorbidities and smaller spectrum for treatment choice. Further studies, focused on elderly follicular lymphoma patients, with their peculiar characteristics, are needed in order to define the best tailored treatment at diagnosis and at the time of relapse in this setting.

    Discordant lymphoma is defined by the simultaneous presence of two or more distinct types of lymphomas at different anatomic sites. With fewer than 20 studies reporting cases of discordant lymphoma to date, the incidence of this condition is believed to be very low. Here, we report a case of discordant lymphoma in a 34-year-old female patient that involved mediastinal large B-cell lymphoma and nodular sclerosis Hodgkin lymphoma in the right supraclavicular lymph nodes. The patient presented with a mass in the mediastinum and enlargement of the right supraclavicular lymph nodes, but no obvious signs of lymphoma. Histological examination revealed that the encapsulated mediastinal mass contained medium- or large-size tumor cells with lightly stained cytoplasm and round vesicular nuclei as well as a high percentage of mitotic cells; strongly positive immunohistochemical staining for PAX5, CD20, and CD79a also was observed. Examination of biopsied right supraclavicular lymph node tissues revealed separation by collagen fibers, extensive inflammatory cell infiltration, and large-size tumor cells, such as Reed-Sternberg cells. These tissues stained strongly positive for PAX5 and CD30, weakly positive for CD15, and negative for Epstein-Barr viral RNA. We also found monoclonal gene rearrangement in the immunoglobulin heavy chain gene in the mediastinal large B-cell lymphoma, but no monoclonal gene rearrangement in the nodular sclerosis Hodgkin lymphoma. These findings suggested that these two lymphomas were not of a common clonal origin. The patient was treated by surgical excision of the mediastinal mass followed by radio-chemotherapy, and no metastasis or recurrence occurred during a follow-up period of 32 months. A review of previously reported cases indicated that the clinical manifestations and pathological features of discordant lymphoma are diverse due to variation in the types of lymphomas involved. Physicians must have an awareness of discordant lymphoma to avoid

    We examined malignant lymphomas and polymorphic reticulosis of nasal cavity, nasopharynx, and palate, diagnosed at Korea Cancer Center Hospital from 1987 to 1996. With immunophenotypic study, we reclassified nasal/nasopharyngeal lymphomas into three categories: CD56-positive T/NK lymphoma, CD56-negative lymphoma and B-cell lymphoma. Malignant lymphomas of nasal cavity, nasopharynx and palate were 95 patient, that comprised 11% of the total lymphoma cases, and it was the most common extranodal lymphoma. Twenty-five percent were B-cell lymphomas and 75 % were T/NK lymphomas. According to site, nasal cavity was the most frequent and 91 % of nasal cavity lymphomas were T/NK type. CD56-positive T/NK comprised 82 % of total T/NK lymphomas and CD56-negative cases were 18 %. In 89 % of total T/NK lymphomas, many tumor cells expressed EBER-1 in their nuclei (CD56+ T/NK lymphoma: 97 % of EBV expression, CD56-T-cell lymphoma; 60%). Only one case (5%) of B-cell lymphoma showed EBER-1 positivity in a few cells. CD56+ T/NK lymphomas showed significantly more angiocentricity and severe necrosis than CD56- cases. Although it has no statistical significance, T/NK lymphomas has a tendency to lower survival rates than B-cell lymphomas at 1 year and 2 year. CD56+ T/NK lymphomas has a tendency to lower survival than CD56- T/NK lymphomas (p > 0.05). Our results of this project will serve important basic materials in diagnosing and studying lymphoma.

    Mediastinal gray zone lymphoma, B-cell lymphomas with intermediate features between classical Hodgkin lymphoma and primary mediastinal B-cell lymphoma, have not been well described in the literature. We report the clinical characteristics and outcomes of a large retrospective series of 99 cases centrally reviewed by a panel of hematopathologists, with a consensus established for the diagnosis. Cases were defined as classical Hodgkin lymphoma-like morphology (64.6%) with primary mediastinal B-cell lymphoma immunophenotype, primary mediastinal B-cell lymphoma-like morphology (30.3%) with classical Hodgkin lymphoma or composite (5.1%) (synchronous occurrence of classical Hodgkin lymphoma and primary mediastinal B-cell lymphoma). The median age was 32 years (13–83 years); 55% were women. Thirteen of 81 evaluable cases (16%) were Epstein-Barr virus-positive. Twenty-eight percent of patients presented primary refractory disease (progression under first-line treatment or relapse within one year). The 3-year event-free and overall survival rates were 63% and 80%, respectively. Patients treated with a standard regimen (RCHOP/ABVD) had worse event-free survival (P=0.003) and overall survival (P=0.02) than those treated with a dose-intensive chemotherapy (high-dose RCHOP/escalated BEACOPP). Rituximab added to chemotherapy was not associated with better event-free survival (P=0.55) or overall survival (P=0.88). Radiotherapy for patients in complete remission had no impact on event-free survival. In multivariate prognostic analysis, ECOG-PS and anemia were the strongest factors associated with a shorter event-free survival and overall survival, respectively. In conclusion, this report describes the largest series of mediastinal gray zone lymphoma. Our data suggest that a dose-intensive treatment might improve the outcome of this rare and aggressive disease. PMID:27758822

    Modern advances in genomics and cancer biology have produced an unprecedented body of knowledge regarding the molecular pathogenesis of lymphoma. The diverse histological subtypes of lymphoma are molecularly heterogeneous, and most likely arise from distinct oncogenic mechanisms. In parallel to these advances in lymphoma biology, several new classes of molecularly targeted agents have been developed with varying degrees of efficacy across the different types of lymphoma. In general, the development of new drugs for treating lymphoma has been mostly empiric, with a limited knowledge of the molecular target, its involvement in the disease, and the effect of the drug on the target. Thus, the variability observed in clinical responses likely results from underlying molecular heterogeneity. In the era of personalized medicine, the challenge for the treatment of patients with lymphoma will involve correctly matching a molecularly targeted therapy to the unique genetic and molecular composition of each individual lymphoma. In this Review, we discuss current and emerging biomarkers that can guide treatment decisions for patients with lymphoma, and explore the potential challenges and strategies for making biomarker-driven personalized medicine a reality in the cure and management of this disease.

    Objective To review the role of cyclic adenosine monophosphate (cAMP) signal pathway in the pathogenesis oflymphoma and explore a potential lymphoma therapy targeted on this signaling pathway.Data sources The data cited in this review were mainly obtained from the articles listed in Medline and PubMed,published from January 1995 to June 2009. The search terms were "cAMP" and "lymphoma".Study selection Articles regarding the role of the cAMP pathway in apoptosis of lymphoma and associated cells and itspotential role in targeted therapy of lymphoma.Results In the transformation of lymphocytic malignancies, several signal pathways are involved. Among of them, thecAMP pathway has attracted increasing attention because of its apoptosis-inducing role in several lymphoma cells. cAMPpathway impairment is found to influence the prognosis of lymphoma. Targeted therapy to the cAMP pathway seems tobe a new direction for lymphoma treatment, aiming at restoring the cAMP function.Conclusions cAMP signal pathway has different effects on various lymphoma cells. cAMP analogues andphosphodiesterase 4B (PDE4B) inhibitors have potential clinical significance. However, many challenges remain inunderstanding the various roles of such agents.

    Full Text Available Xueyan Chen, Lorinda A Soma, Jonathan R FrommDepartment of Laboratory Medicine, University of Washington Medical Center, Seattle, WA, USAAbstract: Despite the relative success of chemotherapy for Hodgkin lymphoma (HL and systemic anaplastic large cell lymphoma (ALCL, novel therapeutic agents are needed for refractory or relapsed patients. Targeted immunotherapy has emerged as a novel treatment option for these patients. Although unconjugated anti-cluster of differentiation (CD30 antibodies showed minimal antitumor activity in early clinical trials, development of antibody–drug conjugates (ADCs appears promising. Brentuximab vedotin is an ADC composed of an anti-CD30 antibody linked to a potent microtubule-disrupting agent monomethyl auristatin E (MMAE. It has the ability to target CD30-positive tumor cells and, once bound to CD30, brentuximab vedotin is internalized and MMAE is released to induce cell cycle arrest and apoptosis. In two phase II trials, objective response was reported in 75% and 86% of patients with refractory or relapsed HL and systemic ALCL, respectively, with an acceptable toxicity profile. Based on these studies, the US Food and Drug Administration (FDA granted accelerated approval of brentuximab vedotin in August 2011 for the treatment of refractory and relapsed HL and ALCL. We review the key characteristics of brentuximab vedotin, clinical data supporting its therapeutic efficacy, and current ongoing trials to explore its utility in other CD30-positive malignancies.Keywords: classical Hodgkin lymphoma, systemic anaplastic large cell lymphoma, CD30, brentuximab vedotin, SGN-35

    Full Text Available Mesenteric panniculitis (MP is a rare disease occasionally complicated with lymphoma. A 55-year old female presented with MP accompanied by malignant lymphoma. This patient was first treated for follicular lymphoma and subsequently for panniculitis. After 6 courses of R-CHOP chemotherapy, the treatment response was partial. An additional course of salvage chemotherapy led to a complete response. Since the mesenteric mass progressed simultaneously with the regression of other lymphoma lesions, we performed a biopsy of the mesenteric mass and pathologically confirmed an MP lesion without lymphoma. Subsequent high-dose chemotherapy led to CR and the MP lesion remained stable. In the present case, MP progressed with chemotherapy. We concluded that mesenteric lesions suspected of progressing or recurring should be diagnosed pathologically even if asymptomatic.

    Full Text Available BACKGROUND: Lymphomas are one of the commonest childhood malignancies. Due to varied clinical features many patients are misdiagnosed and treated for other diseases. It is imperative to keep health workers informed about the current trend of lymphomas in northeastern Nigeria to facilitate prompt diagnosis and treatment. OBJECTIVE: To evaluate the extent of lymphomas at presentation and to define the pattern of presentation in relation to gender and site. MATERIALS AND METHODS: Retrospective analysis of cases of lymphomas over a 15 year period was conducted. Structured questionnaires were used to document demographic characteristics and clinical features. The non-Hodgkin's lymphoma (NHL and Hodgkin's lymphoma (HL cases were categorized using standard classification schemes. Data were analyzed using the Statistical Package for Social Sciences (SPSS software version 16, Illinois, Chicago, USA. Spearman's correlation and Student's t-test were applied where appropriate. A P value < 0.05 was considered significant. RESULTS: Fifty cases of lymphoma, 10 (20% belong to HL and 40 (80% belong to NHL. Lymphoma is common in male, though the male to female preponderance was not significant in both the cases (P = 0.107 and 0.320, respectively. Maxilla was the commonest site of primary malignancy (36% and late presentation of patients were observed. New trend was noticed, the NHL patients present commonly with severe symptoms than HL (P = 0.038. HL was dominated by lymphocytic predominant type, while NHL was dominated by the small non cleaved cells (Burkitt's lymphoma (70%. CONCLUSION: Childhood lymphoma in northeastern Nigeria has a slight shift in varied clinical presentation in favor of NHL. Patients in this study had late presentation.

    Full Text Available In glomerular diseases, the occurence of lymphoma is mostly observed in the form of both minimal change disease and Hodgkin’s lymphoma. The coocurrence of Membranous nephropathy and membranoproliferative glomerulonephritis are generally associated with non-Hodgkin’s lymphoma. While Ig A nephropathy-lymphoma association is rare, it is generally observed in the form of non- Hodgkin’s lymphoma, and there are also cases proposed the cooccurence of Ig A nephropathy and cutaneous T-cell lymphoma. In this case, it is emphasized that IgA nephropathy presented with cresentric glomerulonephritis should be considered in patients with hodgkin’s lymphoma who have sudden renal disorder.

    A 60-year-old woman presented with acute eyelid swelling and a subcutaneous hemorrhage in the right eye. Magnetic resonance imaging showed a spherical tumor of the lacrimal gland. The tumor was removed by the Kroenlein method. We diagnosed as a B-cell lymphoma that is unclassifiable, and intermediate between diffuse large B-cell lymphoma (DLBCL) and Burkitt lymphoma (BL) (intermediate DLBCL/BL) based on its immunohistopathological examination and c-MYC/IgH rearrangement. We administered six cycles of dose-adjusted-EPOCH-R (etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin hydrochloride, and rituximab) therapy, and remission of the lymphoma was obtained. This is the first case of an intermediate DLBCL/BL of a lacrimal gland. PMID:28203109

    Primary gastric T cell lymphoma is rare and mostly of large cell type. In this paper, we present a case of gastric T cell lymphoma morphologically similar to the gastric marginal zone B cell lymphoma of mucosa-associated lymphoid tissue (MALT). Morphologically, the cells are small with abundant clear cytoplasm. Lymphoepithelial lesions are readily identified with diffuse destruction of gastric glands. Immunohistochemically, the neoplastic cells are CD3+/CD4+/CD8-/Granzyme B-. Molecular studies revealed monoclonal T cell receptor gamma gene rearrangement. Clinically, the patient responded initially to four cycles of R-CHOP, but then progressed. Because peripheral T cell lymphoma is usually associated with a poor prognosis, whereas marginal zone B cell lymphoma is an indolent lymphoproliferative disorder, this morphologic mimicry should be recognized and completely investigated when atypical small lymphoid infiltrates with lymphoepithelial lesions are encountered in the stomach.

    Primary mantle cell lymphoma (MCL) is a controversial entity. It is difficult to diagnose MCL in a single organ without lymph node involvement. However, with the advent of PET-CT scans and large panels of immunohistochemistry markers, there have been increasing reports of primary MCL detected in various organs of which the GI tract is the most common. In this case report, we describe the diagnosis and clinical course of a patient who presented with "B symptoms" and respiratory distress. On further investigation, he was found to have a mass in his trachea, which was diagnosed as primary MCL.

    Radiologic, clinical, and pathologic findings are described in 6 young adults with lymphoblastic lymphoma (LBL), an aggressive tumor which has recently become recognized as a serious threat to adults as well as to children. Each patient presented with a mediastinal mass, three of them developing cardiac tamponade and one a superior vena cava syndrome. CT scanning and echocardiography were particularly helpful in defining the lesions. The rapid dissemination of LBL, and its early progression to a leukemic phase call for promt diagnosis and treatment.

    AIM: To heighten recognition of primary pancreatic lymphoma (PPL) in clinical practice.METHODS: A retrospective review of the clinical presentation, imaging characteristics and pathological features of PPL patients were presented, as well as their diagnosis and treatment, in combination with literature review.RESULTS: Histological diagnosis was made in four patients by surgery and in two patients by EUS-FNA. The six PPL patients (5 males and 1 female; age range,16-65 years; mean age, 46 years) had the duration of symptoms for two weeks to three months. The primary presenting symptoms, though not characteristic, were abdominal pain, abdominal masses, weight loss, jaundice, nausea and vomiting. One of the patients developed acute pancreatitis. In one patient, the level of serum CA19-9 was 76.3 μg/L. Abdominal CT scan showed that three of the six tumors were located in the head of pancreas, two in the body and tail, and one throughout the pancreas. Diameter of the tumors in the pancreas in four cases was more than 6 cm, with homogeneous density and unclear borders. Enhanced CT scan showed that only the tumor edges were slightly enhanced. The pancreatic duct was irregularly narrowed in two cases whose tumors were located in the pancreatic head and body, in which endoscopic retrograde cholangiopancreatography (ERCP) showed that the proximal segment was slightly dilated. Two patients underwent Whipple operation, one patient underwent pancreatectomy, and another patient underwent operative biliary decompression. PPL was in stage I E in 2 patients and in stage Ⅱ E in 4 patients according to the Ann Arbor classification system. The diagnosis of B-cell non-Hodgkin's lymphoma was made in all patients histopathologically. All six patients underwent systemic chemotherapy, one of whom was also treated with gamma radiometry. One patient died two weeks after diagnosis, two patients lost follow-up, two patients who received chemotherapy survived 49 and 37 mo, and the remaining

    Oral plasmablastic lymphoma is a rare malignancy that is associated with patients with HIV or other immunosuppression. This article describes a case of a patient with severe haemophilia A (<1% factor VIII) who had medically acquired HIV and hepatitis C, a CD4+ count of 192 cells/μL and a viral load of 33 200 copies/mL. The patient presented with a two-month history of a firm swelling around a lower molar. The tooth was removed and the surrounding tissue biopsied. The importance of obtaining an early definitive diagnosis and seeking adequate medical treatment is discussed.

    The treatment of measles pneumonitis in immunocompromised adults is not established. We describe a patient with Hodgkin's lymphoma who developed acute pneumonia during a measles infection. On day 13, intravenous ribavirin and immunoglobulins were administrated. On day 18, the patient developed acute respiratory failure. An examination of transbronchial pulmonary biopsies showed Warthin-Finkeldey giant cells that are pathognomonic of measles pneumonitis. The patient died despite aggressive supportive care. Our case and a review of literature show that measles pneumonitis is routinely fatal in patients with cancer. We suggest that antiviral drugs should be considered as soon as the diagnosis has been established.

    Five years' experience of operating a Regional Lymphoma Histopathology Panel is described. During this period, approximately 1400 cases were registered of which nearly 1200 were confirmed as malignant lymphoma. Complete concordance of diagnosis was achieved between submitting pathologists and the Panel in two-thirds of cases of Hodgkin's disease and just over half of non-Hodgkin's lymphoma. Most discrepancies in diagnosis were found to be of clinical importance in terms of prognosis and/or therapeutic management of patients. In approximately two-thirds of such instances disagreement arose because of wrong assignment of tumour grade within the main lymphoma class but in one-third of cases the main class of lymphoma was wrongly designated. Panel members experienced similar diagnostic problems as submitting pathologists although to a lesser extent. The existence of the panel has not reduced the proportion of cases causing diagnostic difficulty for submitting pathologists or panel members during the 5 year study period. The principal cause of death was ascertained from death certificates and autopsy findings in nearly half the cases dying during the study period. In approximately half of these infection (largely pulmonary) played a major role while most of the remainder died of various cardiovascular, pulmonary or renal disorders. There was no specific pattern relating to the main lymphoma class. It is concluded that whilst the panel fulfils a useful function in resolving diagnostic difficulties and standardizing lymphoma diagnosis its role is restricted somewhat by the limitations imposed by conventional morphological assessments.

    AIM: To estimate the characteristics of Color Doppler findings and the results of hepatic radionuclide angiography (HRA) in secondary Hodgkin's hepatic lymphoma.METHODS: The research included patients with a diagnosis of Hodgkin's lymphoma with metastatic focal lesions in the liver and controls. Morphologic characteristics of focal liver lesions and hemodynamic parameters were examined by pulsed and Color Doppler in the portal, hepatic and splenic veins were examined. Hepatic perfusion index (HPI) estimated by HRA was calculated.RESULTS: In the majority of patients, hepatomegaly was observed. Lesions were mostly hypoechoic and mixed, solitary or multiple. Some of the patients presented with dilated splenic veins and hepatofugal blood flow. A pulse wave was registered in the centre and at the margins of lymphoma. The average velocity of the pulse wave was higher at the margins ( P >0.05). A continuous venous wave was found only at the margins of lymphoma. There was no linear correlation between lymphoma size and velocity of pulse and continuous wave ( r = 390, P < 0.01). HPI was significantly lower in patients with lymphomas than in controls ( P < 0.05), pointing out increased arterial perfusion in comparison to portal perfusion.CONCLUSION: Color Doppler ultrasonography is a sensitive method for the detection of neovascularization in Hodgkin's hepatic lymphoma and estimation of its intensity. Hepatic radionuclide angiography can additionally help in the assesment of vascularisation of liver lesions.

    2014-01-01

    Full Text Available Introduction. Primary lymphoma of the gallbladder is an extremely rare entity with approximately 50 cases reported so far. In many of these cases the presenting symptoms were mimicking symptomatic gallstone disease and the diagnosis was made postoperatively, especially when the preoperative imaging results were far from suspicious for malignant disease. Patients and Methods. We report a case of primary lymphoma of the gallbladder in an 85-year-old man with gallstone disease, who was admitted for elective cholecystectomy 2 months after an episode of acute cholecystitis and pancreatitis. Histological evaluation of the specimen revealed a small lymphocytic lymphoma of the gallbladder. This type of primary gallbladder lymphoma has not been previously reported. Discussion. The most common primary lymphomas of the gallbladder are MALT lymphomas and diffuse large B-cell lymphomas, although a variety of other histological types have been reported. The association of these lesions with chronic inflammation is the most convincing theory for their pathogenesis. For lesions confined to the gallbladder, cholecystectomy is considered to be sufficient, while supplementary chemotherapy significantly improves prognosis in more advanced disease.

    Classical Hodgkin lymphoma (cHL) is characterized by a low percentage of tumor cells in a background of diverse, reactive immune cells. cHL cells commonly derive from preapoptotic germinal-center B cells and are characterized by the loss of B-cell markers and the varying expression of other hematopoietic lineage markers. This phenotypic variability and the scarcity of currently available cHL-specific cell surface markers can prevent clear distinction of cHL from related lymphomas. We applied the cell surface capture technology to directly measure the pool of cell surface exposed proteins in four cHL and four non-Hodgkin lymphoma (NHL) cell lines. More than 1000 membrane proteins, including 178 cluster of differentiation annotated proteins, were identified and allowed the generation of lymphoma surfaceome maps. The functional properties of identified cell surface proteins enable, but also limit the information exchange of lymphoma cells with their microenvironment. Selected candidate proteins with potential diagnostic value were evaluated on a tissue microarray (TMA). Primary lymphoma tissues of 126 different B cell-derived lymphoma cases were included in the TMA analysis. The TMA analysis indicated gamma-glutamyltranspeptidase 1 as a potential additional marker that can be included in a panel of markers for differential diagnosis of cHL versus NHL. © 2015 WILEY-VCH Verlag GmbH & Co.

    Full Text Available Abstract Background Most lymphomas that involve the tonsil are large B cell lymphomas. Large B-cell lymphoma is a high grade malignancy which progresses rapidly. Tonsillar lymphoma usually presents as either a unilaterally enlarged palatine tonsil or as an ulcerative and fungating lesion over the tonsillar area. Small lymphocytic lymphomas (SLL of the Waldeyer's ring are uncommon. Case presentation We report a 41-year-old male who presented with a ten-year history of snoring. Physical examination revealed smooth bilateral symmetrically enlarged tonsils without abnormal surface change or cervical lymphadenopathy. Palatal redundancy and a narrowed oropharyngeal airway were also noted. The respiratory disturbance index (RDI was 66 per hour, and severe obstruction sleep apnea (OSA was suspected. No B symptoms, sore throat, odynophagia or dysphagia was found. We performed uvulopalatopharyngoplasty (UPPP and pathological examination revealed incidental small B-cell lymphocytic lymphoma (SLL. Conclusion It is uncommon for lymphoma to initially present as OSA. SLL is an indolent malignancy and is not easy to detect in the early stage. We conclude that SLL may be a contributing factor of OSA in the present case.

  16. MicroRNAs in lymphoma, from diagnosis to targeted therapy.

    The crucial role of microRNAs (miRNAs) in major biological processes and cancer development has been extensively described. Some stage-specific miRNAs are involved in B-cell differentiation, from the naïve B-cell stage through germinal center maturation. Assuming that lymphoma cells are derived from B cells at different stages of maturation, miRNAs can be considered as both specific markers and putative target genes. Here, we review the most salient recent publications in this field, highlighting the clinical and therapeutic value of miRNAs in lymphomas. miRNA array-based experiments have indicated that almost all mature lymphoid malignancies can be characterized by a distinct miRNA profile. Recent works have highlighted the crucial roles of miR-155 and miR-17-92 in the pathogeneses of diffuse large B-cell lymphoma and mantle cell lymphoma, respectively, indicating that they represent promising target genes. Novel mechanisms of miRNA deregulation have also been reported, including recurrent somatic mutations, MYC-driven miRNA repression, and cross-talk with other cells in the microenvironment. In experimental models, some lymphomas are considered to be addicted to the sustained expression of targetable oncomiRs, such as miR-155 and miR-21. However, despite these results, which provide considerable information regarding lymphoma pathogenesis, the integration of miRNA analysis for lymphoma diagnosis or treatment in daily practice remains challenging.

    2015-01-01

    Full Text Available Primary non-Hodgkin lymphoma of the liver is a very rare malignancy. In this case report, we describe a case of primary hepatic lymphoma (PHL in a 60-year-old man who presented with lump and pain in the abdomen of 2 months′ duration. The patient had altered liver function, normal serum alfa fetoprotein level (AFP, normal hemogram and bone marrow. A computed tomography scan of the abdomen and pelvis showed an ill-defined hypodense mass with specks of calcification involving the liver, suggestive of primary malignant mass of liver. Diagnosis of PHL was established on the cytology smear and confirmed by immunohistochemistry on tissue biopsy. This case demonstrates that PHL should be considered in the differential diagnosis of space-occupying liver lesions in the presence of a normal level of AFP. Fine needle aspiration cytology is a faster and safer diagnostic modality even in such a rare case. The case has many unique features like negative serology for viruses, no type B symptom and normal lactate dehydrogenase level.

  1. Fertility in female survivors of Hodgkin's lymphoma

    2012-01-01

    Full Text Available Currently, Hodgkin's lymphoma is one of the most curable types of cancer. Patients are often young and so the long-term morbidities of treatment have become of increasing concern. Among these, infertility is one of the most challenging consequences for patients in reproductive age. Premature ovarian failure in premenopausal women is a serious long-term sequel of the toxicity of chemotherapy. The main consequence of this syndrome is infertility, but women also present other symptoms related to estrogen deprivation. Different rates of impaired gonadal function are reported, depending on the patient's age, stage of disease, dose and intensity of chemotherapy and the use of radiation therapy. The most established strategy in female infertility is cryopreservation of embryos after in vitro fertilization. Additionally, the use of oral contraceptives or gonadotropinreleasing hormone analogs (GnRH-a during treatment is under study. This review will provide a general overview of the main studies conducted to evaluate the infertility rate among female Hodgkin's lymphoma survivors and risk factors associated to treatment, different end-point definitions for evaluating fertility and also a brief description of the available strategies for fertility preservation.

    Six consecutive patients with unresected gastric lymphoma which were treated by radiation therapy between November 1976 and March 1989 were reviewed. Radiation therapy was performed using involved fields, total radiation dosages of which ranged from 25.2 to 36 Gy (mean, 29.3 Gy). Five out of the 6 patients were treated with chemotherapy combined with radiation. Regimen of the chemotherapy was CHOP (cyclophophamide, adriamycin, vincristine and prednisone) in most cases. Three out of the 6 underwent probe laparotomy, but the tumors were diagnosed as unresectable due to locally invading the adjacent structures. They were treated by chemo-radiotherapy and 2 of them are surviving as of the present study (40 and 116 months). The other 3 patients were diagnosed as with clinical stage IV disease and 2 of them were successfully treated with chemo-radiotherapy (21 and 66 months, surviving). These data suggest that unresected gastric lymphomas, which are locally advanced or stage IV disease, are treated by chemo-radiotherapy with high curability without any serious complications.

    Lymphoblastic lymphoma (LBL) is an aggressive lymphoma pathologically similar to lymphoblastic leukemia, but primarily presents with nodal or extra-medullary involvement. The aim of this study is to describe outcomes of patients undergoing stem cell transplantation (SCT) for LBL compared to historical data. Thirty-nine patients, of which 54% lacked complete remission (CR), received SCT for LBL between 1990 and 2015; 31 allogeneic and eight autologous. Overall survival (OS) and progression free survival (PFS) at three years for the entire cohort was 41%, the cumulative incidence (CI) of non-relapse mortality (NRM) was 18% at one year, and CI relapse mortality was 28% at one-year and 36% at three years; results similar to historical reports. On multivariate analysis, the use of total-body irradiation (TBI) based conditioning and transplantation in CR were independently predictive of OS and PFS. For patients requiring SCT for LBL, CR and TBI-based conditioning prior to allogeneic SCT may provide improved disease control.

    Burkitt lymphoma (BL) is a rare and highly aggressive type of non-Hodgkin lymphoma. The mortality rate of BL patients is very high due to the rapid growth rate and frequent systemic spread of the disease. A better understanding of the pathogenesis, more sensitive diagnostic tools and effective treatment methods for BL are essential. Metabolomics, an important aspect of systems biology, allows the comprehensive analysis of global, dynamic and endogenous biological metabolites based on their nuclear magnetic resonance (NMR) and mass spectrometry (MS). It has already been used to investigate the pathogenesis and discover new biomarkers for disease diagnosis and prognosis. In this study, we analyzed differences of serum metabolites in BL mice and normal mice by NMR-based metabolomics. We found that metabolites associated with energy metabolism, amino acid metabolism, fatty acid metabolism and choline phospholipid metabolism were altered in BL mice. The diagnostic potential of the metabolite differences was investigated in this study. Glutamate, glycerol and choline had a high diagnostic accuracy; in contrast, isoleucine, leucine, pyruvate, lysine, α-ketoglutarate, betaine, glycine, creatine, serine, lactate, tyrosine, phenylalanine, histidine and formate enabled the accurate differentiation of BL mice from normal mice. The discovery of abnormal metabolism and relevant differential metabolites may provide useful clues for developing novel, noninvasive approaches for the diagnosis and prognosis of BL based on these potential biomarkers.

  5. Exploring Risk Factors for Follicular Lymphoma

    Alexander J. Ambinder

    2012-01-01

    Full Text Available Follicular lymphoma (FL is an indolent malignancy of germinal center B cells with varied incidence across racial groups and geographic regions. Improvements in the classification of non-Hodgkin lymphoma subtypes provide an opportunity to explore associations between environmental exposures and FL incidence. Our paper found that aspects of Western lifestyle including sedentary lifestyle, obesity, and diets high in meat and milk are associated with an increased risk of FL. Diets rich in fruits and vegetables, polyunsaturated fatty acids, vitamin D, and certain antioxidants are inversely associated with FL risk. A medical history of Sjogren's syndrome, influenza vaccination, and heart disease may be associated with FL incidence. Associations between FL and exposure to pesticides, industrial solvents, hair dyes, and alcohol/tobacco were inconsistent. Genetic risk factors include variants at the 6p21.32 region of the MHC II locus, polymorphisms of the DNA repair gene XRCC3, and UV exposure in individuals with certain polymorphisms of the vitamin D receptor. Increasing our understanding of risk factors for FL must involve integrating epidemiological studies of genetics and exposures to allow for the examination of risk factors and interactions between genes and environment.

    Plasmoblastic lymphoma (PBL) is a subtype of the diffuse large B-cell lymphoma, typically present as extranodal disease associated with human immune deficiency virus (HIV) infection. PBLs are often the initial manifestation of AIDS. Here we present a case of PBL concerning the oral cavity. A 34-year-old woman presented a tumor in the oral cavity that involved the maxilla and gingiva (confirmed by CT-scan). The gingival biopsy showed a massive infiltration by large lymphoid cells with round, vesicular nuclei, prominent nucleoli, fine chromatin and an significant amount of basophilic cytoplasm which express CD79a, CD138, cytoplasmic lambda light chain and LCA, without staining for CD20, CD38, CD3 and CTK. Serological analysis confirmed HIV positivity. PBLs lack most B-lineage markers, but many express CD79a in at least some of the cells, therefore generate difficulties in differential diagnosis. Overall assessment and correlation of the histopathological and immunohistochemical features with the clinical findings and serology investigation are the most helpful diagnostic tools and can lead to the final diagnosis.

Many trials have been performed over the last decade using bendamustine not only as monotherapy, but also in combination with other agents including rituximab, vincristine, mitoxantrone, fludarabine, and other agents as therapy for patients with relapsed non-Hodgkin’s lymphomas, and recently was approved for use in therapy of patients with relapsed indolent lymphomas considered refractory to rituximab therapy. As monotherapy, bendamustine induces good responses with only minor side effects. In combination with other agents, efficacy improves, especially when given in combination with rituximab. The drug has also been studied in combination with rituximab as initial therapy for indolent lymphomas, and has excellent activity with less toxicity than R-CHOP (rituximab – cyclophosphamide, hydroxydaunorubicin [Adriamycin], Oncovin [vincristine], and prednisone/prednisolone.Conclusion: Overall, bendamustine has demonstrated promising results as therapy for non-Hodgkin’s lymphomas and should be included in the armamentarium of agents used to treat relapsed indolent non-Hodgkin’s lymphomas and may prove valuable as initial therapy for these diseases. Further studies are being conducted to demonstrate the efficacy of this drug in combination with other agents.Keywords: bendamustine, non-Hodgkin’s lymphomas, relapsed lymphoma

    Monoamine oxidase A (MAOA) is a mitochondrial enzyme that catalyzes oxidative deamination of neurotransmitters and dietary amines and produces H2 O2 . It facilitates the progression of gliomas and prostate cancer, but its expression and functional relevance have not been studied in lymphoma. Here, we evaluated MAOA in 427 cases of Hodgkin and non-Hodgkin lymphoma and in a spectrum of reactive lymphoid tissues by immunohistochemistry on formalin-fixed, paraffin-embedded specimens. MAOA was expressed by Hodgkin Reed-Sternberg (HRS) cells in the majority of classical Hodgkin lymphomas (cHLs) (181/241; 75%), with 34.8% showing strong expression. Weak MAOA was also noted in a minority of primary mediastinal large B-cell lymphomas (8/47; 17%) and in a mediastinal gray-zone lymphoma. In contrast, no MAOA was found in non-neoplastic lymphoid tissues, nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL; 0/8) or any other non-Hodgkin lymphomas studied (0/123). MAOA was more common in Epstein-Barr virus (EBV)-negative compared to EBV-positive cHL (p Hodgkin-lymphoma-derived cell lines did not. The MAOA inhibitor clorgyline reduced the growth of L1236 cells and U-HO1 cells, and shRNA knockdown of MAOA reduced the growth of L1236 cells. Conversely, ectopic overexpression of MAOA increased the growth of MAOA-negative HDLM2 cells. Combined treatment with clorgyline and ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) was more effective in reducing cell growth than either regimen alone. In summary, MAOA is highly expressed in cHL and may reflect the distinct biology of this lymphoma. Further studies on the potential utility of MAOA as a diagnostic marker and therapeutic target are warranted. Copyright © 2017 Pathological Society of Great Britain and Ireland.

    The development of malignant neoplasia following solid organ transplantation and immunosuppression is well recognized in man. Post-transplantation malignant tumours include non-melanoma skin cancers, non-Hodgkin's lymphoma and Kaposi's sarcoma and many of these cancers have a known or suspected viral cause. A similar increased incidence of cancer is seen in cats that have received a renal transplant and lymphoma is the predominant neoplasm in this population. This study examines a population of cats that received renal transplants at the University of Pennsylvania School of Veterinary Medicine and subsequently developed neoplasia. From 1998 to 2010, 111 cats were transplanted and 25 cats developed cancer (22.5%). Fourteen of the 25 cats were diagnosed with lymphoma (56%), making it the most common tumour in this patient population. The median interval between transplantation and diagnosis of lymphoma was 617 days and the median survival time (MST) following the diagnosis of lymphoma was 2 days. Tissues from seven of these cats were available for histopathological review as either samples collected at necropsy examination (n = 5) or biopsy submissions (n = 2). Five of these cats had multiorgan involvement with sites including the liver, spleen, peripheral and mesenteric lymph nodes, small intestine, urinary bladder, heart, mesenteric fat and body wall. Four of the cats with multiorgan disease had involvement of the renal allograft two of which also had lymphoma of the native kidney. All lymphomas were classified as mid to high grade, diffuse large B-cell lymphoma, which is also the most common lymphoma subtype in human cases of post-transplantation lymphoproliferative disorders.

    We report two cases of aggressive thyroid lymphoma in elderly patients that presented as Epub ahead of print large infiltrative thyroid masses with extensive invasion to adjacent structures including trachea, esophagus, and common carotid artery. Ultrasonography displayed irregular shaped, heterogeneous hypoechoic mass, mimicking anaplastic carcinoma. Computed tomography showed heterogeneously enhancing mass compared to surrounding muscles without calcification and hemorrhage. After biopsy, the masses were histopathologically diagnosed as lymphoma. Aggressive primary thyroid lymphoma is rare; therefore, here we report its image features, with emphasis on ultrasonographic findings, and discuss its differential diagnosis.

    Full Text Available Objective. Primary hepatic lymphoma is a rare disease. And the clinical manifestations of this disease are nonspecific. The objective of this paper is to improve clinicians’ understanding of this disease. Methods. We analyzed the clinical characteristics of a case of primary hepatic lymphoma in association with hepatitis B virus infection and reviewed the literature. Conclusion. The clinical manifestations of primary hepatic lymphoma are nonspecific. And it is easily misdiagnosed. Postoperative radiotherapy of patients with early stage was previously speculated to achieve favorable improvement. The application of targeted therapeutic drugs, chemotherapy, or combined local radiotherapy has become the first-line treatment strategy.

    We report on a 78-year-old Japanese woman with a 50-year history of large-plaque parapsoriasis that had evolved into cutaneous T-cell lymphoma. Her large-plaque parapsoriasis had been treated with psoralen plus ultraviolet A for 10 years. Subsequently an isolated nodule appeared on her right lower leg. Prior or concurrent patches or plaques were absent. Histology revealed a diffuse nonepidermotropic infiltrate of large lymphocytes in the dermis, which had enlarged nuclei and prominent nucleoli. A diagnosis of CD30- cutaneous large T-cell lymphoma was made. Following systemic chemotherapy, there was clinical improvement. No evidence of recurrence or systemic lymphoma has subsequently been found.

    Full Text Available Anaplastic large cell lymphoma (ALCL is a distinct type of CD30+ T/null-cell non-Hodgkin′s lymphoma that frequently involves nodal and extranodal sites. The presence of leukemic phase in ALCL is extremely rare and occurs exclusively with ALK1-positive ALCL. We describe two patients with ALK1-positive ALCL who developed a leukemic phase with rapid progression of the disease. Immunophenotypic pattern assessed on peripheral blood by flow cytometry revealed CD45, CD30, and CD25 positivity in both cases but NPM-ALK1 was expressed in only one case. Both patients developed leukemic phase as a terminal event of the disease and we share the immunophenotypic features of both cases.

  4. The Role of c-MYC in B-Cell Lymphomas: Diagnostic and Molecular Aspects.

    Science.gov (United States)

    Nguyen, Lynh; Papenhausen, Peter; Shao, Haipeng

    2017-04-05

    c-MYC is one of the most essential transcriptional factors, regulating a diverse array of cellular functions, including proliferation, growth, and apoptosis. Dysregulation of c-MYC is essential in the pathogenesis of a number of B-cell lymphomas, but is rarely reported in T-cell lymphomas. c-MYC dysregulation induces lymphomagenesis by loss of the tight control of c-MYC expression, leading to overexpression of intact c-MYC protein, in contrast to the somatic mutations or fusion proteins seen in many other oncogenes. Dysregulation of c-MYC in B-cell lymphomas occurs either as a primary event in Burkitt lymphoma, or secondarily in aggressive lymphomas such as diffuse large B-cell lymphoma, plasmablastic lymphoma, mantle cell lymphoma, or double-hit lymphoma. Secondary c-MYC changes include gene translocation and gene amplification, occurring against a background of complex karyotype, and most often confer aggressive clinical behavior, as evidenced in the double-hit lymphomas. In low-grade B-cell lymphomas, acquisition of c-MYC rearrangement usually results in transformation into highly aggressive lymphomas, with some exceptions. In this review, we discuss the role that c-MYC plays in the pathogenesis of B-cell lymphomas, the molecular alterations that lead to c-MYC dysregulation, and their effect on prognosis and diagnosis in specific types of B-cell lymphoma.

    Full Text Available Case Presentation. A 69-year-old Hispanic male, with a past history of diabetes and coronary disease, was admitted for fever, diarrhea, and confusion of 4 weeks duration. Physical examination showed a disoriented patient with multiple ecchymoses, possible ascites, and bilateral scrotal swelling. Hemoglobin was 6.7, prothrombin time (PT 21.4 seconds with international normalized ratio 2.1, partial thromboplastin time (PTT 55.6 seconds, fibrin split 10 µg/L, and lactate dehydrogenase (LDH 1231 IU/L. Except for a positive DNA test for Epstein–Barr virus (EBV infection, extensive diagnostic workup for infections, malignancy, or a neurological cause was negative. Mixing studies revealed a nonspecific inhibitor of PT and PTT but Factor VIII levels were normal. The patient was empirically treated with antibiotics but developed hypotension and died on day 27 of admission. At autopsy, patient was found to have intravascular diffuse large B-cell lymphoma involving skin, testes, lung, and muscles. The malignant cells were positive for CD20, CD791, Mum-1, and Pax-5 and negative for CD3, CD5, CD10, CD30, and Bcl-6. The malignant cells were 100% positive for Ki-67. Discussion. Intravascular large cell B-cell lymphoma (IVLBCL is rare form of diffuse large B-cell lymphoma and tends to proliferate within small blood vessels, particularly capillaries and postcapillary venules. The cause of its affinity for vascular bed remains unknown. In many reports, IVLBCL was associated with HIV, HHV8, and EBV infections. The fact that our case showed evidence of EBV infection lends support to the association of this diagnosis to viral illness. The available literature on this subject is scant, and in many cases, the diagnosis was made only at autopsy. The typical presentation of this disorder is with B symptoms, progressive neurologic deficits, and skin findings. Bone marrow, spleen, and liver are involved in a minority of patients. Nearly all patients have elevated LDH

    An 11-year-old, spayed female domestic shorthair cat was presented for a right flank wound. On clinical examination, a single non-painful skin tear lesion with irregular edges was detected. During the examination, star-shaped cigarette paper-like skin lesions appeared spontaneously. An abdominal mass was also palpated. Feline skin fragility syndrome (FSFS) was suspected and a multicentric lymphoma was diagnosed by fine needle aspiration. The cat's condition declined and it died spontaneously. Post-mortem examination confirmed the diagnosis of lymphoma. Neoplastic lymphocytes were not observed in the skin. Histological analysis of the skin was consistent with the morphological aspects of FSFS. A possible direct link between the two conditions remains a matter of speculation, but this case report provides the first description of FSFS associated with multicentric follicular lymphoma. Thus, multicentric follicular lymphoma should be considered as a differential diagnosis in cats presenting with FSFS.

    2010-08-01

    Full Text Available Abstract Diffuse large B-cell lymphoma usually starts as a rapidly growing mass in an internal lymph node and can grow in other areas such as the bone or intestines. About 1/3 of these lymphomas are confined to one part of the body when they are localized. In the case of a 78-year-old man, an extensive tumour was located on the right thigh. Biopsies of the tumour revealed diffuse proliferation of large lymphoid cells which have totally affected the normal architecture of striated muscle. The patient received multimodality treatment including chemotherapy of the CHOP regimen and adjuvant radiotherapy. Despite this being a fast growing lymphoma, about 3 out of 4 people will have no signs of disease after initial treatment, and about half of all people with this lymphoma are cured with therapy.

    Full Text Available Purpose: We report a rare case of primary uveal lymphoma and characterize it using histopathology and multimodal imaging. Patient and Methods: A 41-year-old male presented with a 2-year history of increasingly blurry vision in his right eye and no systemic symptoms. Examination revealed a retinal detachment and mass lesion in the right eye. Radiologic and histologic testing was performed. Results: Multimodal imaging localized the lesion to the choroid, and fine needle aspiration biopsy diagnosed the lesion as a low-grade B-cell lymphoma. The patient was treated with external beam radiation, resulting in regression of the mass and resolution of the retinal detachment. Conclusions: Primary uveal lymphoma is a rare, usually indolent tumor that carries a good prognosis. In this case, we show that primary uveal lymphoma has distinct findings via histopathology and multimodal imaging, and that imaging after radiation treatment documents disease regression.

    Full Text Available Abstract Background To show magnetic resonance imaging (MRI texture appearance change in non-Hodgkin lymphoma (NHL during treatment with response controlled by quantitative volume analysis. Methods A total of 19 patients having NHL with an evaluable lymphoma lesion were scanned at three imaging timepoints with 1.5T device during clinical treatment evaluation. Texture characteristics of images were analyzed and classified with MaZda application and statistical tests. Results NHL tissue MRI texture imaged before treatment and under chemotherapy was classified within several subgroups, showing best discrimination with 96% correct classification in non-linear discriminant analysis of T2-weighted images. Texture parameters of MRI data were successfully tested with statistical tests to assess the impact of the separability of the parameters in evaluating chemotherapy response in lymphoma tissue. Conclusion Texture characteristics of MRI data were classified successfully; this proved texture analysis to be potential quantitative means of representing lymphoma tissue changes during chemotherapy response monitoring.

    2012-01-01

    Full Text Available Aggressive B-cell lymphomas share high proliferative and invasive attitudes and dismal prognosis despite heterogeneous biological features. In the interchained sequence of events leading to cancer progression, neoplastic clone-intrinsic molecular events play a major role. Nevertheless, microenvironment-related cues have progressively come into focus as true determinants for this process. The cancer-associated microenvironment is a complex network of nonneoplastic immune and stromal cells embedded in extracellular components, giving rise to a multifarious crosstalk with neoplastic cells towards the induction of a supportive milieu. The immunological and stromal microenvironments have been classically regarded as essential partners of indolent lymphomas, while considered mainly negligible in the setting of aggressive B-cell lymphomas that, by their nature, are less reliant on external stimuli. By this paper we try to delineate the cardinal microenvironment-centred dynamics exerting an influence over lymphoid clone progression in aggressive B-cell lymphomas.

    Langerhans cell histiocytosis (LCH) is a rare neoplasm defined as the proliferation of bone marrow langerhans cells, which is a kind of dendritic cells. The major pathological features of LCH are expression of CD1a and S100 as well as Birbeck granules. Its presentation can differ from a mild bone lesion to a multi-systemic evolved malignant neoplasm; however, the latter outcome is almost rare. Thus, LCH is mostly known as a benign neoplasm. In this study, we present a case of LCH followed by Hodgkin lymphoma (HL). Accompaniment of this disease with malignant lymphoma is rare and considered as case report. Several cases in which malignant lymphoma occurred prior to LCH are reported; however, few cases can be found with LCH followed by malignant lymphomas. PMID:25999631

    Primary breast lymphoma (PBL) is a rare entity accounting for less than 1% of all breast malignancies. Diagnostic criteria for primary Hodgkin's lymphoma of the breast are: the presence of sufficient tissue for diagnosis, close interaction between mammary tissue and lymphomatous infiltrate and no evidence or prior diagnosis of widespread lymphoma. Our case illustrates an unusual presentation of Hodgkin's lymphoma of the breast: clinically as inflammatory breast cancer and core biopsy as granulomatous mastitis, the final diagnosis requiring surgical biopsy. Current information regarding this entity is scant, mainly build upon its rarity. In this paper we assess the clinical presentation, the step-by-step diagnosis, the treatment and the importance of immunohistochemistry in this uncommon condition. PMID:26225149

    2014-01-01

    Hemophagocytic lymphohistiocytosis (HLH) is a severe life-threatening disorder, responsible for extensive phagocytosis of hematopoietic cells and causing a multisystem organ failure. If lymphomas are common causes of HLH, the association with Hodgkin's lymphoma is rarely described in children. We report a case of a 9-year-old boy presenting with HLH as an initial manifestation of Hodgkin's lymphoma. He has been suffering from persistent high fever, asthenia, weight loss, and hepatosplenomegaly with no lymphadenopathy. The diagnosis of HLH secondary to infectious disease was initially worn. The patient received high-dose intravenous immunoglobulin with broad-spectrum antibiotics. However, his state got worse with the onset of dry cough and pleural effusion. Histopathologic examination of pleural fluid showed the presence of Reed-Sternberg cells. The outcome was favorable after treatment by corticosteroid and chemotherapy. Hodgkin's lymphoma revealed by HLH is a source of delayed diagnosis and should be borne in mind in children. PMID:25328742

    Langerhans cell histiocytosis (LCH) is a rare neoplasm defined as the proliferation of bone marrow langerhans cells, which is a kind of dendritic cells. The major pathological features of LCH are expression of CD1a and S100 as well as Birbeck granules. Its presentation can differ from a mild bone lesion to a multi-systemic evolved malignant neoplasm; however, the latter outcome is almost rare. Thus, LCH is mostly known as a benign neoplasm. In this study, we present a case of LCH followed by Hodgkin lymphoma (HL). Accompaniment of this disease with malignant lymphoma is rare and considered as case report. Several cases in which malignant lymphoma occurred prior to LCH are reported; however, few cases can be found with LCH followed by malignant lymphomas.

    Published in September 2008, the updated World Health Organization Classification of Tumors of Hematopoietic and Lymphoid Tissues introduces provisional borderline categories for lymphoma cases that demonstrate overlapping clinical, morphological, and/or immunophenotypic features between well-established entities. These overlapping features pose real diagnostic challenges especially in identifying atypical cases of diffuse large B-cell lymphoma, Hodgkin lymphoma, and Burkitt lymphoma. Lymphoma cases showing borderline features between T-cell/histiocyte-rich large B-cell lymphoma and nodular lymphocyte predominant Hodgkin lymphoma are not included within the borderline categories provisionally recognized by the updated classification. Within the borderline categories, there are cases combining features of primary mediastinal large B-cell lymphoma and classical Hodgkin lymphoma. Many of these cases resemble classical Hodgkin lymphoma but have a large number of tumor cells expressing CD20, CD45, and B-cell transcription factors. Alternatively, these cases may resemble primary mediastinal large B-cell lymphoma but contain tumor cells resembling Reed-Sternberg cells and displaying an aberrant phenotype such as CD20(-), CD15(-/+) CD45(+), CD30(+), Pax5(+), OCT2(+/-), and BOB1(+/-). Another new borderline category defining B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma, represents a biologically heterogeneous group. Cases with morphologic features intermediate and with CD10/BCL6 coexpression should be placed in diffuse large B-cell lymphoma/Burkitt lymphoma category if tumor cells also show strong BCL2 staining and/or a Ki67 proliferation index of less than 90%. When MYC rearrangements are present in these cases, the lymphomas often have atypical features, including concurrent rearrangements of BCL2 and/or BCL6 genes (so-called double/triple-hit lymphomas) and more aggressive behavior.

    Angioimmunoblastic T-cell lymphoma (AITL) is a rare subtype of peripheral T-cell lymphoma (PTCL). AITL typically presents with lymphadenopathy, fever, rash, hepatosplenomegaly, and rarely polyarthritis. We report the case of a 50-year-old female who presented with lymphadenopathy, rash, and symmetric polyarthritis. She was later diagnosed with AITL and was treated with chemotherapy with resolution of arthritis. AITL should be suspected in paitents presenting with rheumatoid-like arthritis and diffuse lymphadenopathy. © 2016 Marshfield Clinic.

    Full Text Available Peripheral T-cell lymphomas are a group of rare neoplasms originating from clonal proliferation of mature post-thymic lymphocytes with different entities having specific biological characteristics and clinical features. As natural killer cells are closely related to T-cells, natural killer-cell lymphomas are also part of the group. The current World Health Organization classification recognizes four categories of T/natural killer-cell lymphomas with respect to their presentation: disseminated (leukemic, nodal, extranodal and cutaneous. Geographic variations in the distribution of these diseases are well documented: nodal subtypes are more frequent in Europe and North America, while extranodal forms, including natural killer-cell lymphomas, occur almost exclusively in Asia and South America. On the whole, T-cell lymphomas are more common in Asia than in western countries, usually affect adults, with a higher tendency in men, and, excluding a few subtypes, usually have an aggressive course and poor prognosis. Apart from anaplastic lymphoma kinase-positive anaplastic large cell lymphoma, that have a good outcome, other nodal and extranodal forms have a 5-year overall survival of about 30%. According to the principal prognostic indexes, the majority of patients are allocated to the unfavorable subset. In the past, the rarity of these diseases prevented progress in the understanding of their biology and improvements in the efficaciousness of therapy. Recently, international projects devoted to these diseases created networks promoting investigations on T-cell lymphomas. These projects are the basis of forthcoming cooperative, large scale trials to detail biologic characteristics of each sub-entity and to possibly individuate targets for new therapies.

    Mature T-cell lymphomas are aggressive malignancies. Treatment outcome is poor with conventional chemotherapy. They are about twice as common in Asia as compared with other non-Asian countries. Histone proteins form the basic structure of chromatin, and their acetylation at lysine residues relaxes chromatin structure, facilitating gene transcription. Conversely, histone deacetylation, catalyzed by histone deacetylases, compacts chromatin and represses gene transcription. Histone deacetylase inhibitors are an important class of antineoplastic agents. Chidamide is a novel orally active benzamide-type histone deacetylase inhibitor that has shown in vitro activities against a wide array of neoplasms. In Phase I trials, chidamide showed preferential efficacy in mature T-cell lymphomas. In a pivotal Phase II trial of chidamide in 79 patients with relapsed or refractory mature T-cell lymphomas, an overall response rate of 28% (complete remission/complete remission unconfirmed: 14%) was achieved, with most responses occurring within the first 6 weeks of treatment. The median duration of response (DOR) was 9.9 (1.1–40.8) months. Of 22 responders, 19 patients (86%) had a DOR of ≥3 months and eight patients (36%) had a DOR of >12 months. Angioimmunoblastic T-cell lymphoma and anaplastic large cell lymphoma (anaplastic lymphoma kinase-negative) showed better response rates, with the most durable responses observed in angioimmunoblastic T-cell lymphoma patients. Safety profile was favorable, with very few cases of grade 3/4 toxicities observed. Chidamide is approved by the China Food and Drug Administration for the treatment of relapsed and refractory peripheral T-cell lymphomas. PMID:28138258

    Intravascular large B-cell lymphoma (IVLBCL) is a rare subtype of malignant lymphoma. Although the involvement of adrenal glands in IVLBCL is often observed, primary adrenal IVLBCL is rare. Most reported cases of adrenal IVLBCL showed bilateral lesions resulting in rapidly progressive adrenal failure and poor prognosis. Here, we report a case of slowly progressive primary adrenal IVLBCL manifesting initially with unilateral adrenal incidentaloma. This case is a silent IVLBCL and shows that the enlargement of both adrenal glands can be followed.

    Background: Extracellular circulating DNA (cfDNA) can be found in small amounts in plasma of healthy individuals. Increased levels of cfDNA have been reported in patients with cancer of breast, cervix, colon, liver and it was shown that cfDNA can originate from both tumour and non-tumour cells. Objectives: Levels of cfDNA of a large series of children with lymphoma were evaluated and analyzed in relation with clinical characteristics. Methods: plasma cfDNA levels obtained at diagnosis in 201 paediatric lymphoma patients [43 Hodgkin lymphomas (HL), 45 anaplastic large cell lymphomas (ALCL), 88 Burkitt lymphomas (BL), 17 lymphoblastic (LBL), 8 diffuse large B cell lymphoma (DLBCL)] and 15 healthy individuals were determined using a quantitative PCR assay for POLR2 gene and, in addition, for NPM-ALK fusion gene in ALCL patients. Wilcoxon rank sum test was used to compare plasma levels among different patient subgroups and controls and to analyze relationship between levels of cfDNA and clinical characteristics. Results: Levels of cfDNA in lymphoma patients were significantly higher compared with controls (p<0.0001). CfDNA was associated with median age (p=0.01) in HL, and with stage in ALCL (p=0.01). In HL patients high cfDNA levels were correlated with poor prognosis (p=0.03). In ALCL we found that most of the cfDNA (77%) was non-tumor DNA. Conclusion: level of plasma cfDNA might constitute an important non-invasive tool at diagnosis in lymphoma patients' management; in particular in patients with HL, cfDNA seems to be a promising prognostic biomarker.

    2012-01-01

    Mantle cell lymphoma is a B cell malignancy in which constitutive dysregulation of cyclin D1 and the cell cycle, disruption of DNA damage response pathways, and activation of cell survival mechanisms contribute to oncogenesis. A small number of tumors lack cyclin D1 overexpression, suggesting that its dysregulation is always not required for tumor initiation. Some cases have hypermutated IGHV and stable karyotypes, a predominant nonnodal disease, and an indolent clinical evolution, which suggests that they may correspond to distinct subtypes of the disease. In this review, we discuss the molecular pathways that contribute to pathogenesis, and how improved understanding of these molecular mechanisms offers new perspectives for the treatment of patients.

The major task remaining before us is curing as many patients as possible with their initial therapeutic approach while minimizing the acute toxicities and limiting the lifetime risks of important secondary events such as cardiovascular complications and secondary malignancies. In the 40 years since DeVita et al. developed the mechlorethamine, vincristine, procarbazine, and prednisone chemotherapy regimen, we have learned a great deal about risk stratification to minimize treatment-related toxicity. Positron emission tomography may further assist us in reducing radiation treatment without compromising cures. This review will discuss the development of the chemotherapy regimens used in the management of early and advanced stage HL and the advantages and disadvantages of their use in combination with radiation therapy.

    2015-11-01

    Full Text Available Splenic marginal zone lymphoma (SMZL is a distinct low grade B-cell lymphoma with an immunophenotype similar to that of splenic marginal zone B-cells. Like the normal splenic marginal zone B-cells, SMZLs also show variable features in somatic mutations of their rearranged immunoglobulin genes, with ∼90% of cases harbouring somatic mutations but at remarkably variable degrees, suggesting that SMZL may have multiple cell of origins, deriving from the heterogeneous B-cells of the splenic marginal zone. Notably, ∼30% of SMZLs show biased usage of IGHV1-2*04, with the expressed BCR being potentially polyreactive to autoantigens. Recent exome and targeted sequencing studies have identified a wide spectrum of somatic mutations in SMZL with the recurrent mutations targeting multiple signalling pathways that govern the development of splenic marginal zone B-cells. These recurrent mutations occur in KLF2 (20–42%, NOTCH2 (6.5–25%, NF-κB (CARD11 ∼7%, IKBKB ∼7%, TNFAIP3 7–13%, TRAF3 5%, BIRC3 6.3% and TLR (MYD88 5–13% signalling pathways. Interestingly, the majority of SMZL with KLF2 mutation have both 7q32 deletion and IGHV1-2 rearrangement, and these cases also have additional mutations in NOTCH2, or TNFAIP3, or TRAF3. There is a potential oncogenic cooperation among concurrent genetic changes, for example between the IGHV1-2 expressing BCR and KLF2 mutation in activation of the canonical NF-κB pathway, and between KLF2 and TRAF3 mutations in activation of the non-canonical NF-κB pathway. These novel genetic findings have provided considerable insights into the pathogenesis of SMZL and will stimulate the research in both normal and malignant marginal zone B-cells.

    Ethylene oxide, a high-volume commodity, is an established human carcinogen, although the relevant epidemiologic evidence is limited. We explored the association between occupational exposure to ethylene oxide and risk of lymphoma in a case-control study, including 2347 lymphoma cases first diagnosed in 1998-2004 and 2463 controls, from 6 European countries. The diagnosis of lymphoma was based on the 2001 World Health Organization Classification of lymphoma. Occupational exposure to ethylene oxide was retrospectively assessed by industrial hygienists and occupational physicians based on detailed self-reported information. We modeled risk of lymphoma with unconditional logistic regression analysis as a function of various exposure measures, adjusting for age, sex, and participating center. Thirty-one cases and 27 controls (1.2% of the total study population) were defined as ever having been exposed to ethylene oxide (odds ratio = 1.3 [95% confidence interval [CI] = 0.7-2.1]). Lymphoma risk showed a 4.3-fold increase associated with medium-high frequency of exposure to ethylene oxide (95% CI = 1.4-13). Among major subtypes, chronic lymphocytic leukemia was consistently associated with ethylene oxide exposure, related in a dose-response manner to probability, frequency, and duration of exposure, as well as to cumulative exposure and (less definitively) with exposure intensity. Our results add to the evidence that ethylene oxide is a human carcinogen.

    Full Text Available Introduction Primary Non-Hodgkin’s lymphoma (NHL of the bone is a rare condition. Calcaneus is also an uncommon site for this kind of lymphoma. Case Presentation We hereby present a case of primary non-Hodgkin’s lymphoma of the calcaneus, which was diagnosed and treated at our hospital. The patient had a minor twisting trauma of his ankle but symptoms were present for one year after trauma. The patient complained from instability and swelling of his ankle. After paraclinic assessments, a pathologic lesion was detected in his calcaneus, so incisional biopsy was done and the pathology diagnosis was a large B-cell non-Hodgkin’s lymphoma. Bone marrow assessment was negative for the disease. The patient was treated by chemotherapy and radiotherapy and currently the disease is in remission and patient is doing his previous full activity without any important complication. Conclusions Lymphoma is a rare condition in the foot region but we suggest to be more wise for chronic, uncommon symptoms after minor injuries, as lymphoma of the bone can present mysterious and nonspecific symptoms as was seen in this patient. It may be better to do more assessments to prevent delayed diagnosis of such rare conditions. These rare cases may have atypical imaging and clinical appearance, which can lead to misdiagnosis.

    The risk of hematological malignancies is mainly determined by genetic background, age, sex, race and ethnicity, geographic location, exposure to certain chemicals and radiation; along with the more recently proposed immune factors such as chronic inflammation, immunodeficiencies, autoimmunity, and infections. Paradigmatic examples include the development of lymphoma in Sjögren's syndrome and Hashimoto thyroiditis, gastric MALT lymphoma in Helicobacter pylori infection, or lymphomas associated with infections by Epstein-Barr virus, human herpes virus 8 (HHV 8) and leukemia/lymphoma virus 1 (HTLV-1). A growing number of reports indicates an increased risk of lymphoma, particularly of the anaplastic large cell (ALCL) type. The implants, specifically those used in the past, elicit chronic stimulation of the immune system against the prosthetic material. This is particularly the case in genetically susceptible hosts. We suggest that polyclonal activation may result in monoclonality in those at risk hosts, ultimately leading to lymphoma. We suggest that patients with an inflammatory response against silicone implants be monitored carefully.

    Mucosa associated lymphoid tissue lymphoma (MALT lymphoma) is mostly seen in the gastrointestinal tract; origin from the kidney is extremely rare. Waldenström macroglobulinemia (WM) is a clinicopathologic syndrome denoted by the presence of monoclonal gammopathy in the serum, typically caused by lymphoproliferative disorder. Literature review did not find any report of renal MALT lymphoma accompanied by WM. Herein, for the first time, we report a 72 year-old female patient with a history of chronic kidney disease, presenting with solitary renal mass; MALT lymphoma was confirmed by pathological examination. A serology study identified the presence of WM. No manifestation of hyperviscosity syndrome was noted. Bone marrow biopsy disclosed the concurrent systemic involvement. Her treatment response was uneventful and the renal mass responded with regressive change in size after chemotherapy. The renal function remained stable during follow-up. MALT lymphoma should be considered as an underlying pathology of isolated renal mass. Furthermore, patients with MALT lymphoma should be screened for Waldenström macroglobulinemia and hyperviscosity syndrome.

    In this study, plasma MMP-9 activity was evaluated in cats with lymphoma. Plasma samples were obtained from 26 cats with lymphoma before treatment. From 13 of the included 26 cats, plasma samples were obtained 4 weeks after the initiation of treatment. Plasma samples were also obtained from 10 healthy cats as a control. Plasma MMP-9 activity was examined by gelatin zymography and semi-quantitative value (arbitrary unit; a.u.) for each sample was calculated. Relatively high levels of MMP-9 were observed in cats with lymphoma compared with those in healthy control cats. MMP-9 quantification through zymography showed significantly higher activity in cats with lymphoma (median, 0.63 a.u.; range, 0.23-3.24 a.u.) than in healthy controls (0.22 a.u.; 0.12-0.46 a.u.; P cats with lymphoma may become an appropriate monitoring tool for feline lymphoma. © 2014 John Wiley & Sons Ltd.

    Summary: We present a follow-up of a patient who underwent right-sided subtotal mastectomy and placement of right-sided saline implant in 1968 for a phyllodes tumor and then in 2012 was diagnosed with a rare B-cell type lymphoma of the right breast. In 2015, she was diagnosed with diffuse large B-cell lymphoma involvement of the left breast and left leg and experienced subsequent self-regression of leg lesions without therapy. PMID:27975038

    The diagnosis of marginal zone lymphomas (MZL) is challenged by the lack of specific markers that distinguish them from other low-grade non-Hodgkin B-cell lymphomas. Myeloid cell nuclear differentiation antigen (MNDA) is a nuclear protein that labels myelomonocytic cells as well as B lymphocytes that localize to the marginal zone areas of splenic white pulp. We evaluated MNDA expression in a large series of B-cell lymphomas to assess the sensitivity and specificity of this antigen for the characterization of MZL. A total of 440 tissue sections containing extramedullary B-cell lymphomas and 216 bone marrow biopsies containing atypical or neoplastic lymphoid infiltrates were stained for MNDA by immunohistochemistry. Among the extramedullary lymphoma cases, approximately 67% of nodal MZL, 61% of extranodal MZL, and 24% of splenic MZL expressed MNDA. MNDA was also infrequently expressed in other B-cell neoplasms including mantle cell lymphoma (6%), chronic lymphocytic leukemia/small lymphocytic lymphoma (13%), follicular lymphoma (FL) (4%), lymphoplasmacytic lymphoma (25%), and diffuse large B-cell lymphoma (3%). In contrast, MNDA was only expressed in 2.3% of all bone marrow biopsies involved by lymphoid infiltrates, including 2 cases of FL and one case of MZL. Collectively, these data support the inclusion of MNDA in the diagnostic evaluation of extramedullary B-cell lymphomas, particularly those in which the differential diagnosis is between low-grade FL and MZL.

    The distribution of non-Hodgkin lymphoma subtypes varies around the world, but a large systematic comparative study has never been done. In this study, we evaluated the clinical features and relative frequencies of non-Hodgkin lymphoma subtypes in five developing regions of the world and compared the findings to the developed world. Five expert hematopathologists classified 4848 consecutive cases of lymphoma from 26 centers in 24 countries using the World Health Organization classification, and 4539 (93.6%) were confirmed to be non-Hodgkin lymphoma, with a significantly greater number of males than females in the developing regions compared to the developed world (Pworld (90.7% and 9.3%, respectively). Also, the developing regions had significantly more cases of high-grade B-cell lymphoma (59.6%) and fewer cases of low-grade B-cell lymphoma (22.7%) compared to the developed world (39.2% and 32.7%, respectively). Among the B-cell lymphomas, diffuse large B-cell lymphoma was the most common subtype (42.5%) in the developing regions. Burkitt lymphoma (2.2%), precursor B- and T-lymphoblastic leukemia/lymphoma (1.1% and 2.9%, respectively) and extranodal natural killer/T-cell lymphoma (2.2%) were also significantly increased in the developing regions. These findings suggest that differences in etiologic and host risk factors are likely responsible, and more detailed epidemiological studies are needed to better understand these differences.

    The benefit of intrathecal therapy and systemic rituximab on the outcome of diffuse large B-cell lymphoma at risk of central nervous system disease is controversial. Furthermore, the effect of intrathecal treatment and rituximab in diffuse large B-cell and Burkitt lymphoma with occult leptomeningeal disease detected by flow cytometry at diagnosis is unknown. Untreated diffuse large B-cell (n=246) and Burkitt (n=80) lymphoma at clinical risk of central nervous system disease and having had pre-treatment cerebrospinal fluid were analyzed by flow cytometry and cytology. Spinal fluid involvement was detected by flow cytometry alone (occult) in 33 (13%) diffuse large B-cell and 9 (11%) Burkitt lymphoma patients, and detected by cytology in 11 (4.5%) and 5 (6%) patients, respectively. Diffuse large B-cell lymphoma with occult spinal fluid involvement had poorer survival (P=0.0001) and freedom from central nervous system relapse (Pdisease and not control of central nervous system disease was the principal cause of treatment failure. In diffuse large B-cell lymphoma, systemic rituximab was associated with improved freedom from central nervous system relapse (P=0.003) but not with survival. Our results suggest that patients at risk of central nervous system disease should be evaluated by flow cytometry and that intrathecal prophylaxis/therapy is beneficial.
