    Objective: To report an aggressive case of extranodal natural killer/T-cell lymphoma (NKTCL) of the ethmoid sinus presenting as orbital cellulitis Method: Case report Results: A 56-year-old male presented with right eye redness, reduced vision, and periorbital swelling for 5 weeks duration associated with a two-month history of blocked nose. The visual acuity of the right eye was 6/18. The eye was proptosed with periorbital oedema and conjunctival chemosis. The pupil was mid-dilated but there was no relative afferent pupillary defect. The fundus was normal. The extraocular movements were restricted in all directions of gaze. Nasal endoscopy revealed pansinusitis that corresponded with CT scan orbit and paranasal sinuses findings. Despite treatment, he showed no clinical improvement. Ethmoidal sinus biopsies performed revealed extranodal NKTCL. Further imaging showed involvement of the right orbital contents and its adnexa with intracranial extension into the right cavernous sinus and meninges over right temporal fossa. The patient underwent chemotherapy. However he succumbed to his illness two months after the diagnosis. Conclusion: Extranodal NKTCL is a great mimicker. This case demonstrated how an acute initial presentation of extranodal NKTCL can present as orbital cellulitis with pansinusitis. PMID:28194321

    Extranodal NK/T-cell lymphoma, nasal type (ENKTL-NT) is an aggressive extranodal non-Hodgkin lymphoma most commonly occurring in East Asia and Latin America but with increasing incidence in the U.S. Data on epidemiology, disease presentation, and outcome for European and North American (“Western”) cases are very limited. We review published landmark clinical studies on ENKTL-NT in the West and report in detail recent data, including our institutional experience. We highlight key observations in its epidemiology, natural history, and trends in clinical management. In the U.S., ENKTL-NT is more common among Asian Pacific Islanders (API) and Hispanics compared to non-Hispanic whites. Published studies indicate less heterogeneity in clinical presentation in Western ENKTL-NT compared to Asian patients. While there is variation in age at diagnosis, presence of antecedent lymphoproliferative disorders, and outcomes among racial/ethnic groups, the universal association of ENKTL-NT with EBV and the poor response of this neoplasm to anthracycline-based therapy are consistent across all geographic areas.

    To study the anatomical and histomorphological pattern of extranodal non Hodgkins lymphoma (NHL). Study Design: Descriptive study Place and Duration of Study: The study was carried out at Oncology department Combined Military Hospital Rawalpindi during July 2012 to April 2013. Materials and Methods: All newly diagnosed patients of NHL with extranodal involvement were included in the study. They were categorized as primary extranodal or secondary extranodal lymphomas. Histological pattern and site of involvement were studied. Results: The male to female ratio was 2.2:1 (Male 31, Female 14), and the mean age was 48.16 years (SD=13.40). Primary extranodal involvement was seen in 55.6% of patients. Secondary extranodal involvement was seen in 44.4% of patients. Diffuse large B-cell lymphoma (DLBCL) was the most common type of NHL observed in both primary and secondary extranodal involvement. Gastrointestinal tract was the most common site for primary extranodal involvement and bone marrow was the most common site for secondary extranodal involvement. Conclusion: High frequency of primary extranodal involvement was noted in our study. DLBCL was the most common morphological type observed. Gastrointestinal tract and secondary bone marrow involvement were the most common anatomical sites for primary and secondary extranodal involvement respectively. (author)

    Extranodal NK/T cell lymphoma, nasal type (ENKTL-NT) is an aggressive extranodal non-Hodgkin lymphoma most commonly occurring in East Asia and Latin America but with increasing incidence in the United States. Data on epidemiology, disease presentation, and outcome for European and North American ("Western") cases are very limited. We review published landmark clinical studies on ENKTL-NT in the West and report in detail recent data, including our institutional experience. We highlight key observations in its epidemiology, natural history, and trends in clinical management. In the USA, ENKTL-NT is more common among Asian Pacific Islanders (API) and Hispanics compared to non-Hispanic whites. Published studies indicate less heterogeneity in clinical presentation in Western ENKTL-NT compared to Asian patients. While there is variation in age at diagnosis, presence of antecedent lymphoproliferative disorders, and outcomes among racial/ethnic groups, the universal association of ENKTL-NT with EBV and the poor response of this neoplasm to anthracycline-based therapy is consistent across all geographic areas. Data on epidemiology, disease presentation, and clinical outcomes in mature T cell and NK cell (T/NK cell) neoplasms, including ENKTL-NT, in Europe and North America are very limited. As the classification and diagnostic characterization of the currently recognized T/NK cell lymphoma disease entities continue to evolve, gaps and inconsistencies in data reporting across different studies are being recognized. Despite these limitations, several studies from the USA suggest that the incidence of ENKTL-NT is higher in Asian Pacific Islanders (API) and non-white Hispanics and that outcomes may be worse in non-whites. However, the universal association of ENKTL-NT with Epstein-Barr virus (EBV) across all ethnic groups suggests a common pathogenesis. Given the overlap between the entities included in the category of T/NK cell neoplasms, there is a need to further define

    The purpose of this review is to discuss and illustrate the spectrum of appearances of extranodal lymphoma in the thorax, including the lungs, pleura, heart, thymus, chest wall, thoracic spine, and breast, using current cross-sectional imaging techniques, such as multidetector computed tomography, positron-emission tomography/computed tomography, magnetic resonance imaging, and sonography. Extranodal lymphoma can affect any organ or tissue in the thorax, and can be mistaken for other inflammatory or neoplastic conditions. This review should alert the radiologist to consider extranodal lymphoma in the appropriate clinical setting to ensure timely diagnosis, correct staging, and accurate post-treatment evaluation to optimize treatment regimens.

    1996-01-01

    Objective: To review the approach to the diagnosis, classification, assessment, treatment and continuing management of patients with primary extranodal non-Hodgkin's lymphoma, and the management of generalized disease with the emphasis on the current role of salvage treatment with high dose chemotherapy and stem cell/bone marrow support strategies. Non-Hodgkin's lymphoma may involve any part of the body. Many lymphomas, such as MALT, angiocentric T-cell, etc., commonly present in extranodal sites. Lymphomas presenting in the GI tract, and head and neck, are most common with the single most common site being the stomach. Gastric lymphoma is associated with Helicobacter pylorii and is most common in areas endemic for Helicobacter pylorii infection. Recent advances in the understanding of the etiology of gastric MALT, thyroid, and intestinal lymphomas present new opportunities for the application of novel therapeutic approaches e.g. antibiotic therapy for Helicobacter pylori and early stage IPSID. Lymphomas presenting in the orbit, thyroid, breast, bone, extradural and skin are of interest because of the importance of expert RT in securing local control. Primary brain lymphomas present a particular challenge to the radiation oncologist. Although localized, primary brain lymphomas are extremely difficult to control. Rare sites of extranodal lymphoma include testis, female genital tract, and lung. Extranodal lymphomas are often localized and cure with RT or CMT is possible. They represent a assorted group of diseases with diverse presentations, prognosis, sensitivity to RT and expected outcome. They are of particular importance to radiation oncologists as they require special attention to patterns of spread and treatment planning. The principles of management of primary extranodal lymphoma, however, follow those applicable to localized nodal presentations. Although primary extranodal lymphomas are highly curable, a proportion of patients will fail with disseminated

    Malignant lymphomas are differentiated into Hodgkin's and non-Hodgkin's-lymphoma (NHL). The following article discusses the imaging of extranodal NHL in supradiaphragmatic localizations. Lymphoma can affect nearly all tissues, and represent a rare entity as primary extranodal NHL. A secondary involvement of non-nodal tissue as consequence of a generalized lymphoproliferative disease is more common,and may be seen as well in HIV-positive patients defining AIDS. As extranodal lymphoma mimick the radiologic appearance of other malignant tumors, direct diagnosis without histologic analysis is often impossible. The article describes typical manifestations of lymphoma of the lungs, the head and neck area including the large glands, and rare localizations as the heart or the breast. (orig.) [de

    The purpose of this study was to examine, retrospectively, national-wide clinical data of patients with localized extranodal non-Hodgkin's lymphoma (NHL) who were treated by radiation therapy with or without chemotherapy. The survey was carried out at 25 radiation oncology institutions in Japan in 1998. In 1999, according to the Revised European American Lymphoma (REAL) classification, central pathological review conducted at Aichi cancer center was carried out for the data from 7 radiation oncology institutions. The 5-year progression free survival rates (PFS) were calculated to identify prognostic factors. Survey: Data from 1, 141 patients with stage I and II NHL were recruited from 1988 through 1992. Of them, 787 patients, who were treated using definitive radiotherapy with or without chemotherapy for intermediate and high-grade lymphomas in Working Formulation, constituted the core of this study. Primary tumors arose mainly from extra-nodal organs (71%) in the head and neck (Waldeyer's ring: 41%, thyroid gland: 7%, nasal cavities: 5%, oral cavities: 4%, sinus: 3%, orbital structures: 3%, skin: 2% and etc.). The median age of 60 years for patients with extra-nodal NHL was higher than that of 56 years for patients with nodal NHL (p<0.01). Female were dominant in incidence of extra-nodal NHL arising from the thyroid gland, skin and gastrointestinal tract. The percentage of stage I to the extra-nodal NHL from orbit, sino-nasal presentation was higher than that of other NHLs. The percentage of stage II to the extra-nodal NHL from Waldeyer's ring and thyroid gland was higher than that of other NHLs. Central pathological review was carried out for pathological data from 79 patients (Waldeyer's ring: 45, thyroid gland: 19, sinonasal cavities: 15). Of these, diffuse large B cell lymphoma (DLBCL) composed 63% of all patients, mucosa associated lyumphoid tissue lymphoma (MALT-L): 16%, Natural Killer/T cell lymphoma (NK/T-L): 11%, and mantle cell lymphoma: 5% in REAL

    To report a clinical, histopathological and immunohistochemical findings in a case of primary extranodal marginal zone lymphoma of the uvea associated with massive diffuse extraocular episcleral extension and focal infiltration of the optic nerve and meninges, clinically presented as longstanding uveitis masquerade syndrome. Interventional case reports with histopathological correlation. We describe a 80-year-old male patient with a 3-year history of chronic recurrent hypertensive (pan) uveitis associated with ocular pain, unresponsive to topical and systemic anti-inflammatory, immunosuppressive, antibiotic/antiviral and antiglaucomatous therapy. Because the eye was not salvageable with conservative treatment, enucleation of blind and painful eye was performed. Findings from histopathological and immunohistochemistry examination of the enucleated eye showed an extranodal marginal zone lymphoma of the uveal tract with massive epibulbar extension and optic nerve and meningeal penetration. During almost 3 years of clinical course and 6 months after the enucleation, there were no systemic manifestations of lymphoma, and patient has not required subsequent treatment. Primary lymphoproliferative lesions of the uvea, comprising the iris, ciliary body and choroid are very rare, associated with epibulbar extension extremely and with optic nerve and menigeal penetration exceptionally. Despite its rarity, primary lymphoma of the uvea should be included in the differential diagnosis particularly in older patients with longstanding recurrent uveitis.

    The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A 51-year-old healthy female with good performance status presented for gynecologic surgery for a benign condition. A preprocedure chest x-ray showed a right lower lobe infiltrate. A subsequent computed tomography (CT) scan of the chest with contrast revealed a large consolidative right lower lobe mass with surrounding inflammation ( Fig 1A ). Bronchoscopy with biopsy revealed a low-grade lymphoma with the following immunophenotype: CD45 + , CD20 + , BCL2 + , CD10 negative, CD5 negative, cyclin D1 negative, and Ki-67 index of less than 5%. Morphology and immunohistochemistry were most consistent with pulmonary extranodal marginal zone lymphoma (ENMZL; Fig 2 ). The patient was asymptomatic and denied fevers, sweats, weight loss, shortness of breath or dyspnea on exertion, or cough. Her history was notable for exposure to parrots over several months before presentation. Complete staging with a CT of the chest, abdomen, and pelvis with contrast redemonstrated disease that was localized to the chest with mild compression of the pulmonary vasculature but no other evidence of lymphoma. She was referred to discuss management of stage I AE pulmonary ENMZL lymphoma.

    Full Text Available Mature natural killer /T-cell (NK/T-cell lymphomas are a rarely occurring subgroup of Non Hodgkin Lymphomas (NHL. A large majority of NK/T cell lymphomas are extranodal. Nasal type is the most common one. As clinical symptoms are usually nasal obstruction associated with mass lesion and epistaxis in extranodal NK/T cell lymphomas. Their diagnosis is usually delayed when the disease is advanced, it may have serious consequences. The aim of the present article was to present the clinical, radiological and histopathological findings of a 69-year old female patient who had refractory ulcerated wound on left side of nose and followed for soft tissue infection. It was diagnosed with extranodal NK/T cell lymphoma after deep biopsy was obtained from the lesion and to discuss this rare disease in view of literature data.

    2012-01-01

    Extra-nodal lymphomas may arise in any organ, and different histological subtypes occur in distinct patterns. Prognosis and treatment depend not only on the histological subtype and disease extent, but also on the particular involved extra-nodal organ. The clinical course and response to treatment...... for the more common extra-nodal organs, e.g. stomach, Waldeyer's ring, skin and brain, are fairly well known and show significant variation. A few randomised trials have been carried out testing the role of radiotherapy in these lymphomas. However, for most extra-nodal lymphomas, randomised trials have...... not been carried out, and treatment decisions are made on small patient series and extrapolations from nodal lymphomas. Hopefully, wide international collaboration will make controlled clinical trials possible in the less common extra-nodal lymphomas. Modern highly conformal radiotherapy allows better...

    2015-01-01

    Full Text Available Background: Malignant lymphomas arising in extranodal sites are intriguing. The histological types of lymphomas vary from one site to another. This study is undertaken to diagnose and categorize extranodal lymphomas using histochemistry and immunohistochemistry (IHC. Materials and Methods: Formalin processed paraffin blocks and hematoxylin and eosin stained sections were used for routine histology. IHC was done in all cases. Results: We have encountered 31 cases of extra nodal lymphomas over a period of 3 years. The tumors occurred at different sites, including brain, nasopharynx, nose, gastrointestinal tract, thyroid, bone, testis, breast, lung, vagina, and skin. Majority of the cases were B-cell lymphomas, while four cases were T-cell lymphomas. Among the B-cell lymphomas diffuse large B-cell lymphoma was the most common variant. Conclusion: This study reiterates the key role of IHC particularly when the differential diagnosis includes an undifferentiated epithelial malignancy and a high-grade lymphoma in the extranodal sites as the treatment modalities and prognosis are different.

    Extranodal involvement is a well-known prognostic factor in patients with diffuse large B-cell lymphomas (DLBCL). Nevertheless, the prognostic impact of the extranodal scoring system included in the conventional international prognostic index (IPI) has been questioned in an era where rituximab treatment has become widespread. We investigated the prognostic impacts of individual sites of extranodal involvement in 761 patients with DLBCL who received rituximab-based chemoimmunotherapy. Subsequently, we established a new extranodal scoring system based on extranodal sites, showing significant prognostic correlation, and compared this system with conventional scoring systems, such as the IPI and the National Comprehensive Cancer Network-IPI (NCCN-IPI). An internal validation procedure, using bootstrapped samples, was also performed for both univariate and multivariate models. Using multivariate analysis with a backward variable selection, we found nine extranodal sites (the liver, lung, spleen, central nervous system, bone marrow, kidney, skin, adrenal glands, and peritoneum) that remained significant for use in the final model. Our newly established extranodal scoring system, based on these sites, was better correlated with patient survival than standard scoring systems, such as the IPI and the NCCN-IPI. Internal validation by bootstrapping demonstrated an improvement in model performance of our modified extranodal scoring system. Our new extranodal scoring system, based on the prognostically relevant sites, may improve the performance of conventional prognostic models of DLBCL in the rituximab era and warrants further external validation using large study populations.

    We represent a rare case of lung adenocarcinoma accompanied by extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT). The patient was a 66-year-old male presented with 1 month history of recurrent cough and hemoptysis. Chest CT showed solitary ground-glass opacity (GGO) in the upper lobe of the right lung and mediastinal lymph node enlargement in station 3p. A CT-guided transthoracic needle biopsy was performed. Tissue specimens of the GGO revealed a typical adenocarcinoma. Histopathologic diagnosis of mediastinal lymph node was extranodal marginal zone lymphoma of MALT. Because of its rarity, extranodal marginal zone lymphoma of MALT should be considered in the differential diagnosis when we encounter mediastinal lymphadenopathy in patients with lung adenocarcinoma.

    Follicular lymphoma (FL) is the most common indolent B cell lymphoma in the United States and a quarter of patients present with stage I disease. The objective of this study was to examine if primary site of disease influences survival in early stage lymphoma. The most common extranodal primary sites were the integumentary system (8%), followed by the GI tract (6.4%) and head & neck (5.6%). We stratified patients into a pre-rituximab era (1983-1998) and the rituximab era (1999-2011). In multivariable analysis, integumentary disease was associated with better overall survival (Hazard Ratio [HR], 0.77; Confidence Interval [CI], 0.66-0.9) while primary site FL of the nervous system (HR, 2.40; CI, 1.72-3.38) and the musculoskeletal system (HR, 2.14; CI, 1.44-3.18) were associated with worse overall survival when compared to primary nodal FL. Treatment in the pre-rituximab era, male gender and older age at diagnosis were associated with worse survival. We queried the SEER database from 1983 to 2011. We included all adult patients (>18 years) with histologically confirmed stage I FL, active follow-up, and a single primary tumor. A total of 9,865 patients met eligibility criteria, with 2520 (25%) having an extranodal primary site. We classified the primary sites by organ or anatomic location into 11 sites. Primary site of disease is a prognostic factor for patients with early stage FL and may help identify subsets of patients that could benefit from early, aggressive treatment.

    Extranodal lymphomas (ENLs) comprise about a third of all non-Hodgkin lymphomas (NHL). Radiation therapy (RT) is frequently used as either primary therapy (particularly for indolent ENL), consolidation after systemic therapy, salvage treatment, or palliation. The wide range of presentations of ENL, involving any organ in the body and the spectrum of histological sub-types, poses a challenge both for routine clinical care and for the conduct of prospective and retrospective studies. This has led to uncertainty and lack of consistency in RT approaches between centers and clinicians. Thus far there is a lack of guidelines for the use of RT in the management of ENL. This report presents an effort by the International Lymphoma Radiation Oncology Group (ILROG) to harmonize and standardize the principles of treatment of ENL, and to address the technical challenges of simulation, volume definition and treatment planning for the most frequently involved organs. Specifically, detailed recommendations for RT volumes are provided. We have applied the same modern principles of involved site radiation therapy as previously developed and published as guidelines for Hodgkin lymphoma and nodal NHL. We have adopted RT volume definitions based on the International Commission on Radiation Units and Measurements (ICRU), as has been widely adopted by the field of radiation oncology for solid tumors. Organ-specific recommendations take into account histological subtype, anatomy, the treatment intent, and other treatment modalities that may be have been used before RT.

    Full Text Available Extranodal NK/T-cell lymphoma (ENKTCL is a highly aggressive mature NK/T-cell neoplasm marked by NK-cell phenotypic expression of CD3ε and CD56. While the disease is reported worldwide, there is a significant geographic variation with its highest incidence in East Asian countries possibly related to the frequent early childhood exposure of Epstein–Barr virus (EBV and specific ethnic–genetical background, which contributes to the tumorigenesis. Historically, anthracycline-based chemotherapy such as CHOP (cyclophosphamide, adriamycin, vincristine, and prednisone was used, but resulted in poor outcomes. This is due in part to intrinsic ENKTCL resistance to anthracycline caused by high expression levels of P-glycoprotein. The recent application of combined modality therapy with concurrent or sequential radiation therapy for early stage disease, along with non-anthracycline-based chemotherapy regimens consisting of drugs independent of P-glycoprotein have significantly improved clinical outcomes. Particularly, this neoplasm shows high sensitivity to l-asparaginase as NK-cells lack asparagine synthase activity. Even still, outcomes of patients with advanced stage disease or those with relapsed/recurrent disease are dismal with overall survival of generally a few months. Thus, novel therapies are needed for this population. Clinical activity of targeted antibodies along with antibody–drug conjugates, such as daratumumab (naked anti-CD38 antibody and brentuximab vedotin (anti-CD30 antibody conjugated with auristatin E, have been reported. Further promising data have been shown with checkpoint inhibitors as high levels of programmed death-ligand 1 expression are observed in ENKTCL due to EBV-driven overexpression of the latent membrane proteins [latent membrane protein 1 (LMP1 and LMP2] with activation of the NF-κB/MAPK pathways. Initial case series with programmed death 1 inhibitors showed an overall response rate of 100% in seven relapsed

    Full Text Available Waldeyer's ring is the primary site of Non-Hodgkin's Lymphoma (NHL involvement in approximately 5 to 10% of all lymphoma patients. Of all Waldeyer's ring NHLs, the tonsil is the most frequent site,followed by the nasopharynx. Lymphomas arising from base of the tongue are less frequent, accounting for 7% of all primary Waldeyer's ring NHLs. The possible differential diagnosisincludes Squamous Cell Carcinoma (SCC, which is the most common malignancy of the tongue base, salivary gland malignancy, (adenoid cystic carcinoma or mucoepidermoidcarcinoma and infection processes, such as tuberculosis. Here we present a case of 43 year old male presenting with mass lesion of the base of tongue and odynophagia. The diagnosis was initially made by ne needle aspiration of this lesion. Subsequent imaging investigations revealed a lobulated mass inltrating bowel loop in the right iliac fossa. Histopathological and immunohistochemistry tests for both lesions conrmed extra-nodal, primary NHL Bcell diffuse, large cell type.

    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.

    Objective: Although radiation therapy is frequently used in the treatment of ocular adnexal lymphoma, it is uncertain whether it is curative, or whether it simply provides local control in a systemic disease. Extranodal marginal zone (mucosa-associated lymphoid tissue [MALT] type) lymphoma, a recently described type of low-grade lymphoma, is often localized at diagnosis and may therefore potentially be curable with local therapy. We analyzed the pathologic and clinical features of 165 cases of ocular adnexal lymphoma to determine the proportion that were MALT lymphomas, and to compare the frequency of primary versus secondary involvement, the frequency of localized disease, and the probability for local and distant recurrences after radiation therapy in MALT lymphoma relative to other lymphomas. Methods: Clinical and pathologic (morphologic and immunophenotypic) findings were reviewed in 165 cases of ocular adnexal lymphoma diagnosed between 1974 and 1994. The lymphomas were classified according to the recently described Revised European-American Lymphoma Classification Scheme which newly incorporated the diagnostic category of extranodal marginal zone (MALT) lymphoma. Staging information was available in 73 primary cases. Radiation was given as either photons (for intraorbital disease) or electrons (for superficial disease). Photon treatment primarily consisted of a wedged pair of anterior plus anterior-oblique fields to a median dose of 39.6 Gy (range 19.8 - 46 Gy) at 1.8 Gy per fraction. Electron treatment consisted of an en face field to a median dose of 30 Gy (range 25.6 - 40 Gy) at 2.5 Gy per fraction. Survival data were analyzed by the Kaplan-Meier actuarial method. P-values for differences between frequencies of lymphoma types and stages were calculated by chi square. Results: In 133 patients with no known prior history of lymphoma (primary cases), MALT lymphoma accounted for 55%, while other cases were follicle center lymphoma (FCL) (22%), low grade

    Extranodal NK/T-Cell lymphoma, nasal type (NKTLN) is a disease that mainly affects the nasal cavity and the paranasal sinuses. Early nasal symptoms are nonspecific, simulating sinus infection. With disease progression, necrosis of the nasal mucosa increases, hindering histological diagnosis. Thus, multiple biopsies may be necessary until definitive diagnosis. Most studies on NKTLN address the hematological and immunological aspects of the disease. To present data from a Brazilian quaternary hospital, with emphasis on the clinical aspects of the disease, and to correlate the findings with the most recent literature data. Case study of seven patient files. Patients were evaluated on their medical history, number of biopsies necessary, association with Epstein-Barr virus, treatment, and outcome. All patients had nonspecific nasal complaints and underwent at least three cycles of antibiotic therapy. The earlier a biopsy was performed, the fewer biopsies were required to diagnose the disease and start treatment. However, this fact did not translate into better prognosis. The otolaryngologist plays a fundamental role in the prognosis of NKTLN and can shorten time between symptom onset and treatment of the patient.

    Full Text Available Endobronchial involvement of extrapulmonary malignant tumors is uncommon and mostly associated with breast, kidney, colon, and rectum carcinomas. A 68-year-old male with a prior diagnosis of colon non-Hodgkin lymphoma (NHL was admitted to the hospital with a complaint of cough, sputum, and dyspnea. The chest radiograph showed right hilar enlargement and opacity at the right middle zone suggestive of a mass lesion. Computed tomography of thorax revealed a right-sided mass lesion extending to thoracic wall with the destruction of the third and the fourth ribs and a right hilar mass lesion. Fiberoptic bronchoscopy was performed in order to evaluate endobronchial involvement and showed stenosis with mucosal tumor infiltration in right upper lobe bronchus. The pathological examination of bronchoscopic biopsy specimen reported diffuse large B-cell lymphoma and the patient was accepted as the endobronchial recurrence of sigmoid colon NHL. The patient is still under treatment of R-ICE (rituximab-ifosfamide-carboplatin-etoposide chemotherapy and partial regression of pulmonary lesions was noted after 3 courses of treatment.

    The mechanisms promoting malignant transformation from chronic Helicobacter pylori-gastritis to gastric extranodal marginal zone lymphoma (MALT lymphoma) are insufficiently characterized. This follow-up study aimed to validate candidate microRNAs (miRs) in the process of neoplastic transformation. MicroRNA expression signatures (n=20) were generated for a total of 60 cases of gastric lesions ranging from Wotherspoon 0-5 employing a quantitative real-time polymerase chain reaction (PCR) approach. Morphological and immunohistochemical characterization of the cohort was supplemented by PCR-based immunoglobulin heavy chain recombination studies. Quantitative expression of miR-150, miR-142.3p, miR-375 and miR-494 was significantly de-regulated in samples from MALT lymphoma compared to those from gastritis. The previously reported up-regulation of miR-150 in marginal zone lymphoma of MALT type was verified in an independent cohort of lymphoma samples employing a modified methodology. This further substantiates the role of miR-150 as a potential oncomiR in MALT lymphoma.

    Extranodal natural killer T-cell lymphoma (NKTCL), nasal type, is a rare and aggressive malignancy that occurs predominantly in Asian and Latin American populations. Although Epstein-Barr virus infection is a known risk factor, other risk factors and the pathogenesis of NKTCL are not well understood. We aimed to identify common genetic variants affecting individual risk of NKTCL. We did a genome-wide association study of 189 patients with extranodal NKTCL, nasal type (WHO classification criteria; cases) and 957 controls from Guangdong province, southern China. We validated our findings in four independent case-control series, including 75 cases from Guangdong province and 296 controls from Hong Kong, 65 cases and 983 controls from Guangdong province, 125 cases and 1110 controls from Beijing (northern China), and 60 cases and 2476 controls from Singapore. We used imputation and conditional logistic regression analyses to fine-map the associations. We also did a meta-analysis of the replication series and of the entire dataset. Associations exceeding the genome-wide significance threshold (p<5 × 10(-8)) were seen at 51 single-nucleotide polymorphisms (SNPs) mapping to the class II MHC region on chromosome 6, with rs9277378 (located in HLA-DPB1) having the strongest association with NKTCL susceptibility (p=4·21 × 10(-19), odds ratio [OR] 1·84 [95% CI 1·61-2·11] in meta-analysis of entire dataset). Imputation-based fine-mapping across the class II MHC region suggests that four aminoacid residues (Gly84-Gly85-Pro86-Met87) in near-complete linkage disequilibrium at the edge of the peptide-binding groove of HLA-DPB1 could account for most of the association between the rs9277378*A risk allele and NKTCL susceptibility (OR 2·38, p value for haplotype 2·32 × 10(-14)). This association is distinct from MHC associations with Epstein-Barr virus infection. To our knowledge, this is the first time that a genetic variant conferring an NKTCL risk is noted at

    Full Text Available Background/Aim. Bronchus-associated lymphoid tissue (BALT lymphoma is a rare subtype of low grade marginal zone B cell lymphoma representing 10% of all MALT lymphomas. The purpose of this study was to analyze the outcome of this group of patients comparing prognostic parameters and therapy modalities. Methods. A total of eight patients with BALT lymphoma had diagnosed between January 1998 - April 2008 at the Institute of Hematology, Clinical Center of Serbia, Belgrade, and they were included in this retrospective analysis. Results. Male/female ratio was 2/6, the median age was 64 years (range 37-67 years. Six patients had nonspecific respiratory symptoms and all of them had B symptoms. The patients were seronegative for HIV, HCV and HBsAg. Three patients had Sjogren's syndrome, rheumatoid arthritis and pulmonary tuberculosis, respectively. Seven patients were diagnosed by transbronchial biopsy and an open lung biopsy was done in one patient. Patohistological findings revealed lymphoma of marginal zone B cell lymphoma: CD20+/CD10-/CD5-/CyclinD1- /CD23-/IgM- with Ki-67+<20% of all cells. According to the Ferraro staging system, five patients had localized disease (CS I-IIE and three had stage IVE; bulky tumor mass had 3 patients. All patients had Eastern Cooperative Oncology Group (ECOG performance status (PS 0 or 1. Five patients received monochemotherapy with chlorambucil and 3 were treated with CHOP regimen (cyclophosphamide, doxorubicin, vincristine and prednisone. A complete response (CR was achieved in 5 patients and a partial response (PR in 3 of them, treated with chlorambucil monotherapy and CHOP regimen. All patients were alive during a median follow-up period of 49 months (range 6- 110 months. Three patients relapsed after monochemotherapy into the other extranodal localization. They were treated with CHOP regimen and remained in stable PR. Conclusion. BALT lymphoma tends to be localised disease at the time of diagnosis, responds well

    Extranodal natural killer/T-cell lymphoma (ENKL) has heterogeneous clinical manifestations and prognosis. This study aims to evaluate the prognostic impact of absolute monocyte count (AMC) in ENKL, and provide some immunologically relevant information for better risk stratification in patients with ENKL. Retrospective data from 163 patients newly diagnosed with ENKL were analyzed. The absolute monocyte count (AMC) at diagnosis was analyzed as continuous and dichotomized variables. Independent prognostic factors of survival were determined by Cox regression analysis. The AMC at diagnosis were related to overall survival (OS) and progression-free survival (PFS) in patients with ENKL. Multivariate analysis identified AMC as independent prognostic factors of survival, independent of International Prognostic Index (IPI) and Korean prognostic index (KPI). The prognostic index incorporating AMC and absolute lymphocyte count (ALC), another surrogate factor of immune status, could be used to stratify all 163 patients with ENKL into different prognostic groups. For patients who received chemotherapy followed by radiotherapy (102 cases), the three AMC/ALC index categories identified patients with significantly different survivals. When superimposed on IPI or KPI categories, the AMC/ALC index was better able to identify high-risk patients in the low-risk IPI or KPI category. The baseline peripheral monocyte count is shown to be an effective prognostic indicator of survival in ENKL patients. The prognostic index related to tumor microenvironment might be helpful to identify high-risk patients with ENKL

    Extranodal natural killer/T cell lymphoma, nasal type (ENKTL) is an aggressive disease with a poor prognosis, requiring risk stratification in affected patients. We designed a new prognostic model specifically for ENKTL to identify high-risk patients who need more aggressive therapy. We retrospectively reviewed 158 patients who were newly diagnosed with ENKTL. The estimated 5-year overall survival rate was 39.4 %. Independent prognostic factors included total protein (TP) 100 mg/dL, and Korean Prognostic Index (KPI) score ≥2. We constructed a new prognostic model by combining these prognostic factors: group 1 (64 cases (41.0 %)), no adverse factors; group 2 (58 cases (37.2 %)), one adverse factor; and group 3 (34 cases (21.8 %)), two or three adverse factors. The 5-year overall survival (OS) rates of these groups were 66.7, 23.0, and 5.9 %, respectively (p KPI model alone (p KPI model alone.

    Primary non-Hodgkin's lymphoma occurs quite seldom in the nasopharynx, therefore reports on this topic are rare in medical literature. The treatment results of 30 irradiated patients (40 to 60 Gy) are presented. The period of the study ranges from 1960 to 1985. 13 patients with low grade lymphoma and 17 patients with high grade lymphoma according to the Kiel classification form the basis of this study. The overall actuarial 5-year survival rate is 24%. This also applies for the subgroups of low grade and high grade lymphomas with a 5-year survival rate of 24%, respectively. The evaluation of the patients without generalization in the course of disease shows that the prognosis of stage IE patients with 43% was superior to the one of stage IIE patients with 25% (p [de

    Purpose: To determine whether there are any differences in therapeutic response, patterns of systemic recurrence, and prognosis of patients with extranodal natural killer (NK)/T-cell lymphoma, nasal type, by the cyclooxygenase-2 (COX-2) expression. Patients and Methods: Thirty-four patients with Ann Arbor Stage I and II extranodal NK/T-cell lymphoma who underwent chemotherapy or radiotherapy, or both, were retrospectively reviewed. These patients were divided into two groups according to their immunohistochemical staining for COX-2 expressions: a COX-2-negative group (n = 10 patients) and a COX-2-positive group (n = 24 patients). The treatment response, patterns of treatment failure, and survival data for the patients were compared between the COX-2-positive and negative groups. Results: There was no significant difference in the clinical profiles between the COX-2-negative and COX-2-positive groups. All patients (100%) in the COX-2-negative group achieved complete response after initial treatment, whereas only 14 patients (58%) in the COX-2-positive group achieved complete response (p = 0.03). Compared with the patients in the COX-2-negative group, those in the COX-2-positive group had a significantly lower 2-year systemic recurrence-free survival rate (100% for the COX-2-negative group vs. 54% for the COX-2-positive group) (p = 0.02) and a decreased 5-year overall survival rate (70% for the COX-2-negative group vs. 32% for the COX-2-positive group) (p = 0.06). Conclusion: Cyclooxygenase-2 expression can serve as a predictive factor for poor treatment response, higher systemic recurrence, and unfavorable prognosis in patients with extranodal NK/T-cell lymphoma, nasal type

    Extranodal natural killer (NK)/T-cell lymphoma is a very rare and aggressive disease characterized histopathologically by an Epstein-Barr virus (EBV)-positive atypical lymphoid cytotoxic infiltrate, extensive vascular destruction, and prominent tissue necrosis. It commonly shows cutaneous lesions that primarily or secondarily mimic cellulitis at the primary site. We report on a very rare case of extranodal NK/T-cell lymphoma, nasal type of skin/soft tissue, in a 64-year-old man, and describe the radiological findings. The condition was misdiagnosed as cellulitis of the left arm based on initial noninvasive clinical and radiologic work-up

    Posttransplant lymphoproliferative disorders (PTLDs) are a heterogeneous group of hematolymphoid proliferations arising in the context of chronic immunosuppression. The common and indolent B-cell lymphomas, including extranodal marginal zone lymphomas (ENMZLs) of mucosa-associated lymphoid tissue (MALT), are excluded from the category of PTLD in the current World Health Organization classification. We report a case of Epstein-Barr virus (EBV)-positive bronchial-associated lymphoid tissue (BALT) lymphoma involving the lungs of a transplant patient. Aside from history of cardiac transplant, young patient age, and EBV positivity, the histopathologic findings were indistinguishable from usual BALT lymphoma. We review the literature of ENMZL occurring in immunocompromised patients and present this case for consideration that this specific entity is a PTLD. We believe that additional studies might lend strength to the hypothesis that this particular group of EBV-positive, posttransplant ENMZLs merits classification and management as PTLDs. © American Society for Clinical Pathology, 2017.

    Sjögren's syndrome (SS) is a systemic autoimmune disease characterized by the infiltration of lymphocytes into exocrine glands, resulting in the typical sicca symptoms. Unlike adults, primary SS is a very rare condition in childhood, and the risk of malignancy in juvenile SS (JSS) has not been defined. We report the detection of extranodal marginal zone B-cell lymphoma (EMZL) occurring in two children with SS. Fine needle aspiration of the salivary glands (SG) showed nonspecific findings that led to delayed diagnosis of SS. The diagnosis of B-cell lymphoma associated with JSS was based on morphologic and immunohistochemical staining done during the biopsy. To highlight awareness of EMZL as a timely and appropriate update of an unusual complication in children with SS.

    Between January 1986 and August 1993, 63 patients with primary extranodal Non-Hodgkin lymphoma of head and neck region, stages IE and IIE were treated with radiotherapy. The histological classification followed the Kiel classification, staging the Ann Arbor classification. Patient characteristics: 33 Male, 30 female; age 18 to 84 years; tumor localisation: Tonsils 26, nasopharynx 7, oropharynx 8, paranasal sinus 11, salivary glands 7, floor of mouth/gingiva 3, larynx 1. Mean follow-up is 74 months. Low-grade lymphoma in stages I and II CS were treated with definitive radiation therapy according to the concepts of epithelial tumors of the same localisation (target volume and technique).The adjuvant dose was 30 Gy and in the tumor volume 40 Gy, 2 Gy daily. 28 patients were registered, 18 in stage I and 10 in stage II. High-grade lymphoma were treated with definitive radiation therapy according to the concepts of epithelial tumors of the same localisation, too. The dose was 40 respectively 50 Gy, followed by 4 course of adjuvant chemotherapy with CHOP. Thirty-five patients were enrolled, of whom only 10 received chemotherapy. The overall 5-year survical rates were for low-grade 67% and for high grade lymphoma 88%. The corresponding relapse-free survival rates were 54/68%, respectively. Only 1 patient failed within the irradiated target volume. Recurrences occurred at sites distant to the irradiated volume in nodal and extranodal regions. Prognosis was influenced by histologic grade. Significant trends were not observed for other potential pretreatment parameters (age, stage, localisation, bulk). (orig./MG) [de

    Purpose: To investigate the role of early or up-front radiotherapy (RT), the optimal RT dose required to achieve appropriate treatment outcome and prognostic factors for patients with localized extranodal NK/T-cell lymphoma, nasal-type, in the upper aerodigestive tract. Methods and Materials: Eighty-two patients were reviewed. Eight patients were treated with chemotherapy (CT) alone, 9 patients received RT alone, and 65 patients were given combined modality treatment of CT and RT (CMT). Of those 74 patients receiving RT, 31 patients were given up-front RT, whereas CT was the initial therapy for 43 patients and 41 of those 43 patients received early RT. Results: Five-year overall survival (OS) and disease-free survival (DFS) were 52.3% and 39.2%, respectively. RT was the only independent prognostic factor for both OS and DFS at both the univariate and multivariate level. The 5-year OS and DFS were better in patients receiving ≥54 Gy of RT as compared with that of <54 Gy (5-year OS 75.5% vs. 46.1%, p = 0.019; 5-year DFS 60.3% vs. 33.4%, p = 0.004). Up-front RT presented better survival in Stage I patients when compared with that of initial CT followed by early RT (5-year OS 90.0% vs. 48.9%, p = 0.012; 5-year DFS 78.7% vs. 39.9%, p = 0.021). Conclusion: Early or up-front RT had an essential role in improved OS and DFS in patients with localized extranodal NK/T-cell lymphoma, nasal-type, in the upper aerodigestive tract. The recommended tumor dose was at least 54 Gy. Up-front RT may yield more benefits on survival in patients with Stage I disease

    Background: Extranodal natural killer (NK)/T-cell lymphoma, nasal type (ENKTL) is an aggressive disease with poor prognosis, requiring risk stratification. However, the prognosis of ENKTL is not fully defined and needs supplementation. We hypothesised that fasting blood glucose (FBG) may be a new prognostic factor for ENKTL. Methods: We retrospectively analysed 130 patients newly diagnosed with ENKTL. Results: Both univariate analysis and multivariate analysis revealed that FBG >100 mg dl−1 was associated with a poor outcome. Patients with FBG >100 mg dl−1 at diagnosis had more adverse clinical features, achieved lower complete remission rates (P=0.003) and had worse overall survival (PKPI) scores with different survival outcomes (PKPI.

    The gastrointestinal tract is the most common site for extranodal involvement by non-Hodgkin's lymphoma. However, primary appendiceal lymphomas presenting as perforated acute appendicitis are very rare: they occur in only 0.015% of all gastrointestinal lymphoma cases. The management of this condition is still controversial, and a multimodality approach (e.g., surgery, radiation therapy, and chemotherapy) is the optimal treatment. In these cases, appendiceal non-Hodgkin's lymphomas typically manifest with acute symptoms in patients with no prior lymphoma history. Additionally, we treated our patient with a right hemicolectomy and postoperative multiagent chemotherapy.

    Full Text Available Primary extranodal malignant lymphoma of the thyroid is a rare entity composed of mostly neoplastic transformation of germinal center-like B cells (GCB or memory B cells. Other B-cell-type malignancies arising primarily in the thyroid have rarely been described. Immunohistochemical examination of autopsied primary malignant lymphoma of the thyroid in an 83-year-old Japanese female revealed the presence of a non-GCB subtype of diffuse large B-cell lymphoma (DLBCL without the typical codon 206 or 265 missense mutation of MYD88. The lack of the highly oncogenic MYD88 gene mutation, frequently observed in DLBCL of the activated B-cell (ABC subtype, and the detection of an extremely aggressive yet local clinical phenotype demonstrated that the present case was an exceptional entity of the type3 (non-GCB and non-ABC subtype.

    Objective: To evaluate the efficacy of PVD chemo-regimen (Pegaspargase, vincristine and dexamethasone) combined with intensity-modulated radiotherapy (IMRT) for patients with early-stage extranodal nasal NK/T-cell lymphoma (ENKL). Methods: Clinical data of 52 patients with early-stage ENKL were collected during May 2010 and June 2015 in Department of Lymphoma, Cancer Hospital of Guizhou Medical University, and these patients firstly received a concurrent chemoradiotherapy of two-cycle of PVD and IMRT (gross tumor volume primary: 12.6-59.4 Gy) and then 2 to 4 cycles of PVD as subsequent chemotherapy, the efficacy and adverse responses were retrospectively analyzed and observed. Results: Follow-up stopped until December 2015, complete remission was seen in 44 cases (84.6%) and partial remission 7 cases (13.5%), out of 52 cases. A total of 1 case died of progression disease during treatment and within 1 year after treatment, 1 case died of pulmonary infection within 1 week after treatment, 2 cases survived with tumor; so the objective response rate and clinical benefit rate were both 98.1%, 1-year, 2-year and 3-year overall survival rates and progression free survival rates were all 93.6%, 1-year and 2-year disease free survival rates were both 90.3%; the correlation analysis showed that the radiotherapy dose was related to the curative effect ( P PVD regimen and IMRT have a good therapeutic effect and adverse response can be tolerated.

    Extranodal natural killer/T-cell lymphomas (NK/TL), rare in Europe, are Epstein-Barr virus (EBV) associated lymphomas with poor outcomes. Here, we determined the virus type and analyzed the EBV latent membrane protein-1 (LMP1) gene sequence in NK/TL from French patients. Six clones of viral LMP1 were sequenced by Sanger technology in blood from 13 patients before treatment with an l-asparaginase based regimen and, for 8 of them, throughout the treatment. Blood LMP1 sequences from 21 patients without any known malignancy were tested as controls. EBV Type A was identified for 11/13 patients and for all controls. Before treatment, a clonal LMP1 gene containing a 30 bp deletion (del30) was found in 46.1% of NK/TL and only in 4.8% of controls. Treatment was less effective in these patients who died more rapidly than the others. Patients with a deleted strain evolving toward a wild-type strain during treatment reached complete remission. The LMP1 gene was sequenced by highly sensitive next-generation sequencing technology in five NK/TL nasopharyngeal biopsies, two of them originating from the previous patients. Del30 was present in 100% of the biopsies; two viruses at least coexisted in three biopsies. These results suggest that del30 may be associated with poor prognosis NK/TL and that strain evolution could be used as a potential marker to monitor treatment. © 2016 UICC.

    Angioimmunoblastic T cell lymphoma (AITL) is a peripheral T cell non-Hodgkin lymphoma with an aggressive fatal course and it has varied clinical presentation with an uncommon presentation when they present as soft tissue masses or when there is spill in the peripheral blood or there are composite lymphomas that are rare presentations. Common presentations include lymphadenopathy, fever and systemic symptoms, hemolytic anemias, skin rashes, and rheumatoid arthritis. The classical histopathology is absence of follicles in lymph nodes with presence of high endothelial venules and the tumor cells of small to medium-sized lymphocytes with pale cytoplasm mixed with reactive T cells. On immunohistochemistry, the cells are positive for CD3, CD4, CD10, BCL2, and CXCL13. In this observational study, the clinicopathologic presentation and the immunohistochemical profile of five cases who initially presented with a soft tissue mass which is an extremely rare presentation of this rare type of non-Hodgkin lymphoma that was diagnosed at our center with peripheral blood and bone marrow involvement and the clinicopathologic presentation, immunohistochemical profile, and response to treatment on follow-up are correlated with the literature review. One case had a fulminant and aggressive course and was fatal within 2 months of diagnosis. The rest of the four cases are on regular chemotherapy and follow-up. Our five cases had presented with soft tissue masses, two in the axillary regio,n two in the hand, and one in the scapular region with an extranodal presentation, and there was associated lymphadenopathy which developed subsequently with classic histomorphology and immunohistochemical findings. The age range was 46-54 years and all five cases were males. Three cases were with anemia (hemoglobin range 6.5-8.0 mg/dl) and all five cases were having peripheral blood plasmacytosis. Histopathology was classic with paracortical involvement with polymorphous population of cells with

Nowadays, induction chemotherapy (CT followed by RT consolidation is often used. For patients who get complete response (CR after CT, whether RT dose can be safely reduced or not remains unknown. This retrospective study compared the survival outcomes between patients who received higher dose (>50 Gy and lower dose (≤50 Gy RT after CR was attained by CT. One hundred and forty four patients of early stage ENKTL got CR after induction CT and received RT consolidation. Thirty-one patients received lower dose RT (median 46 Gy, range, 36–50 Gy, and 113 patients received higher dose RT (median 56 Gy, range, 52–66 Gy. In univariate survival analysis, age >60, local tumor invasion, and non-asparaginase-based CT were associated with inferior progression-free survival (PFS and overall survival (OS. However, there were no differences in PFS and OS between patients treated with higher and lower dose RT, which was confirmed in the multivariate survival analysis. Furthermore, reduced dose RT did not affect local control rate. Most common RT-related side effects were grade 1/2 mucositis and dermatitis, and the incidence rate of grade 3 mucositis or dermatitis was lower in patients treated with reduced dose RT (9.7% vs 15.0% for mucositis, and 6.5% vs 17.7% for dermatitis. In conclusion, this study found that RT dose could be safely reduced without

    Purpose: This study aims to evaluate the outcome and pattern of failure in a large cohort of patients with Stage I NK/T-cell lymphoma of the upper aerodigestive tract treated with radiotherapy alone. Methods and Materials: The pathological diagnosis was confirmed using standard criteria. All patients were treated with high-dose extended-field radiotherapy alone. The median dose was 50 Gy. The primary tumor was located in the nasal cavity (n = 80), Waldeyer ring (n = 5), or oral cavity (n = 2). Results: The overall response to radiotherapy was achieved in 85 of 87 (97.7%) patients, with a complete response rate of 95.4% and a partial response rate of 2.3%. The 5-year overall survival, progression-free survival, and local control rates for all patients were 80%, 69%, and 93%, respectively. Twenty patients (23%) had disease progression or relapse. Of these, 15 patients (17%) developed systemic extranodal disseminations, whereas only 4 (5%) patients had local relapse and 4 (5%) patients had lymph node relapse. Conclusions: Our study suggests that high-dose extended-field radiotherapy alone is a curative therapy and shows favorable clinical outcome in patients with Stage I disease. With the high possibility of local control and primary failure of systemic dissemination, the integration of optimal radiotherapy with more effective systematic therapy is warranted to bring additional improvement to the outcome for these patients.

    This study aims to analyze clinical and pathological characteristics of ocular adnexal extranodal marginal zone B-cell lymphoma (EMZL) accompanying IgG4-positive cells. Fifty patients with a diagnosis of primary non-conjunctival ocular adnexal EMZL were enrolled in this study. The number of IgG4-positive cells and the ratio of IgG/IgG4 were evaluated by immunohistochemistry in the biopsy specimens. The patients were divided into two groups based on the absolute number and the ratio of IgG4-positive cells (IgG4-posivite vs IgG4-negative groups). The demographic data, clinical staging at diagnosis, histopathological characteristics, and response to initial treatment were comparatively analyzed between the 2 groups. Five (10%) of 50 patients were defined as IgG4-positive group, and all the cases showed characteristic histological features such as extensive plasma cell infiltration and dense fibrosis. Most of these patients (4 of 5 patients) had lymphoma of the lacrimal gland. The patients from the IgG4-positive group showed a lower response rate to initial treatment (87.5 vs 33%, p = 0.03) than IgG4-negative group with a median follow-up period of 38 months. A part of the ocular adnexal EMZLs were accompanied with IgG4-positive cells. Significantly, most IgG4-positive ocular adnexal EMZLs occurred in the lacrimal gland, and can be related with a more frequent treatment failure. PMID:26111022

    To investigate the clinical significance of interleukin-17 (IL-17) level in patients with extranodal NK/T-cell lymphoma(ENKTL). Eighty patients with nasal ENKTL who received radiotherapy, chemotherapy or radiotherapy combined with chemotherapy from January 2011 to January 2012 were enrolled in the study. Eighty healthy volunteers were selected as the controls (control group). About 5 ml of peripheral blood was collected from all patients and controls. IL-17 level was determined by ELISA. The age, sex, ECOG score, B symptoms, LDH level, lymph node involvment, Ann Arbor stage, IPI, KPI, peripheral blood lymphocyte and lymph node metastasis, number of lymphocytes and monocytes in peripheral blood were recorded. All patients were followed up for 3 year progression-free survival (PFS) and overall survival (OS). The average IL-17 level in patients with ENKTL was 6.48 pg/ml and the average concentration of IL-17 in control group was 0.56 pg/ml (PKPI, lymphocyte count and monocyte cell count. The sensitivity and specificity of IL-17 were 74.5% and 73.7% respectively, and the optimal threshold was 3.49 pg/ml and AUC was 0.799 (95% CI: 0.688-0.909) (P<0.01). The PFS and OS were longer in the patients with IL-17≤3.49 pg/ml and longer in the patients without lymph node involvement and Ann Arbor I. Multivariate analysis showed that independent predictors of PFS and OS in patients with ENKTL were plasma IL-17 levels and age (P<0.05). ENKTL patients with different clinical characteristics have different levels of IL-17, the different level of IL-17 has different effects on prognosis of patients with ENKTL.

    Purpose: To evaluate the effectiveness of concurrent chemoradiation therapy (CCRT) with 40 Gy followed by consolidation chemotherapy for localized extranodal natural killer (NK)/T-cell lymphoma (ENKTL), nasal type. Methods and Materials: From August 2004 to August 2012, 62 patients with newly diagnosed stage IE to IIE ENKTL underwent CCRT followed by consolidation chemotherapy. The median RT dose was 40 Gy. Cisplatin, 30 mg/m{sup 2}, was administered weekly during the RT course. Responders to CCRT were encouraged to undergo consolidation chemotherapy. Three different consolidation chemotherapy regimens were used consecutively: VIPD (etoposide, ifosfamide, cisplatin, and dexamethasone); VIDL (etoposide, ifosfamide, and dexamethasone followed by intramuscular injection of L-asparaginase); and MIDLE (methotrexate, etoposide, ifosfamide, mesna, and L-asparaginase). Results: The median follow-up period was 49 months (range 8-112). After completion of CCRT, 56 patients (90.3%) had a complete response, 4 (6.4%) had a partial response, 1 (1.6%) had stable disease, and 1 patient (1.6%) had progressive disease (PD). Consolidation chemotherapy was recommended to 61 patients, after excluding the patient with PD, but was actually delivered to 58. Of these 58 patients, 56 (96.5%) had a complete response and 2 (3.5%) had PD. During the follow-up period, 17 patients (including 3 with PD) experienced progression. The median interval to progression was 11 months (range 1-61). Local failure developed in 6 patients, of whom, 2 had developed progression outside the RT field. For all patients, the 3-year overall survival, progression-free survival, and local control rates were 83.1%, 77.1%, and 92.4%, respectively. Grade ≥3 nonhematologic toxicity developed in only 3 patients (4.8%). Conclusions: Excellent clinical outcomes were achieved using CCRT with 40 Gy followed by consolidation chemotherapy. Additional investigation, however, is warranted to confirm our findings.

    Lymphomas are the most common non-epithelial tumors of the head and neck and its incidence has increased in recent decades. Around 10% are extranodal lymphomas, and in more than half of the cases are located in Waldeyer's lymphatic ring. The most common presenting symptoms are odynophagia and dysphagia (68%), and symptoms suggestive of oropharyngeal cancer such as cough, hoarseness, earache, feeling of occupation in the back of the mouth, throat or neck. In non-Hodgkin lymphomas in this location, B symptoms (weight loss, fever and sweating) are rare (5%). The histological subtype of each individual lymphoma affects the evaluation, therapy and prognosis. Copyright © 2012 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

    Full Text Available Linfomas não-Hodgkin (LNH extranodais representam cerca de um terço de todos os linfomas e atualmente apresentam taxa de incidência maior que a de linfomas nodais. Diferenças entre LNH nodais e extranodais incluem etiologia, formas de apresentação e resposta terapêutica, entretanto não dispomos de dados na nossa população. Este estudo teve como objetivo caracterizar os LNH extranodais diagnosticados no Hospital Aristides Maltez, em Salvador-Bahia. Foram avaliados, retrospectivamente, 145 diagnósticos de linfoma não-Hodgkin, segundo a OMS-2001, no período de janeiro de 1999 a julho de 2001. A freqüência de linfomas extranodais foi de 30,3%. A idade média dos pacientes foi de 55,6 anos e a relação homem/mulher foi de 1:1. A maioria dos pacientes apresentava estadios avançados (III ou IV de Ann Arbor, presença de sintomas B, LDH normal, bom desempenho pela escala do ECOG e IPI entre zero e dois. Nove pacientes estão vivos e em remissão completa (22,5% após um seguimento médio de 23 meses. O sítio extranodal mais comumente acometido foram as tonsilas, seguidas pela cavidade oral, pele e trato gastrointestinal, dentre outros. O linfoma difuso de grandes células B foi o mais comum subtipo histológico, seguido pelo linfoma anaplásico de grandes células. Concluímos que o mais freqüente sítio extranodal de apresentação em nosso estudo difere da maioria da literatura, porém nossa freqüência de linfoma extranodal é semelhante à mesma.Extranodal non-Hodgkins lymphomas represent approximately one third of all lymphomas and currently have an incidence higher than nodal lymphomas.

    Full Text Available The head and neck is the second most common region for extranodal lymphomas. The most common site is the Waldeyer's ring, and involvement of the base of tongue is extremely rare. We present a rare case of a young female with primary non-Hodgkin's lymphoma (NHL of the base of tongue. A 23-year-old female presented with a history of foreign body sensation in her throat for a month. Oral examination revealed a lobulated smooth mass at the base of tongue. Contrast-enhanced computed tomography neck shows polypoidal homogeneously enhancing soft tissue lesion in the base of tongue extending till the lateral pharyngeal wall. The biopsy of the lesion was reported as NHL. Hodgkin's lymphoma should be kept in the differential diagnosis of swelling arising from the base of tongue. We report a rare and varied presentation of extranodal lymphoma. A careful clinical evaluation supported by histopathological and radiologic investigations will help in identifying the disease at an early stage, resulting in a better prognosis.

    The therapeutic outcome of chemotherapy in NK/T cell lymphoma (NTCL) has not been well documented until now. The aims of this study were to investigate the outcome of chemotherapy and to evaluate the clinical factors influencing the responsiveness to chemotherapy. Between 1995 and 2000, 59 patients received anthracycline-based chemotherapy as an initial treatment. Forty-five patients had nasal NTCL, whereas 14 had extranasal NTCL. Forty-one patients had stage I/II and 18 had stage III/IV disease. Epstein-Barr virus status was positive in 67.6% of cases. The results of initial chemotherapy were complete remission in 35.6% of the patients, 2-year disease-free survival in 22.9% and 2-year overall survival in 44.2%.

    The therapeutic outcome of chemotherapy in NK/T cell lymphoma (NTCL) has not been well documented until now. The aims of this study were to investigate the outcome of chemotherapy and to evaluate the clinical factors influencing the responsiveness to chemotherapy. Between 1995 and 2000, 59 patients received anthracycline-based chemotherapy as an initial treatment. Forty-five patients had nasal NTCL, whereas 14 had extranasal NTCL. Forty-one patients had stage I/II and 18 had stage III/IV disease. Epstein-Barr virus status was positive in 67.6% of cases. The results of initial chemotherapy were complete remission in 35.6% of the patients, 2-year disease-free survival in 22.9% and 2-year overall survival in 44.2%. Adjuvant radiotherapy after chemotherapy did not improve outcome in stage I/II nasal NTCL. The International Prognostic Index was a significant prognostic factor of complete remission rate, and stage was also significant for disease-free survival.

    Full Text Available Sjögren’s syndrome is a chronic autoimmune disease characterized by the presence of lymphocytic infiltrates in exocrine glands, mainly salivary and lacrimal glands, which result in xerophthalmia and xerostomia. About half of the patients develop systemic complications, including lymphoproliferative disorders. We report a case of a 27-year-old woman with a diagnosis of Sjögren’s syndrome and a suspicion of respiratory system involvement in the course of granulomatosis with polyangiitis. Histopathological examination of a skin lesion suggested marginal zone B-cell lymphoma. After pathological and immunohistochemical evaluation of all available previous biopsy samples and the medical documentation the diagnosis of extranodal marginal zone B-cell lymphoma stage IV according to the Ann Arbor classification was rendered. The patient was referred to the Department of Haematology and was treated with R-CVP (cyclophosphamide, vincristine, prednisone, rituximab.

    Our patient was an 86-year-old man who had worked as a lathe operator for 40 years. He had no history of tuberculosis, pyothorax, or autoimmune disease. He had not been exposed to asbestos. He was asymptomatic, but an imaging study showed gradually increasing pleural plaques. A biopsy specimen of a pleural lesion showed sclerosis of the pleura and diffuse infiltration of small- to medium-sized B lymphocytes. Polymerase chain reaction-based analysis detected monoclonal rearrangement of immunoglobulin heavy-chain genes. Histologic diagnosis was extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue type (MALT lymphoma). The lymphoma was negative for Epstein-Barr virus. We report a rare case of a metal worker with MALT lymphoma arising in the pleura with pleural fibrous plaques. It is speculated that MALT lymphoma might develop in the background of pneumoconiosis. Inflammatory and/or immunologic reactions to metal particles might contribute to the oncogenesis of this tumor. Copyright © 2012 Elsevier Inc. All rights reserved.

    The aim of this study was to evaluate whether the maximum standardized uptake value (SUVmax) of (18)F-fluorodeoxyglucose (FDG) correlates with the International Prognostic Index (IPI) and the presence of extranodal involvement in patients with Diffuse Large B-Cell Lymphoma (DLBCL). 77 patients (age: 57.2±18.5, 40F, 37M) with DLBCL who underwent FDG PET/CT for initial staging were included. SUVmax of the predominant lesions were compared to Ann Arbor stage, IPI scores, the presence of extranodal involvement and the number extranodal sites. PET/CT detected nodal (n:25) and extranodal involvement (n:52) in all the patients. In 27 patients, extranodal disease could only be detected by PET. SUVmax of the predominant lesion in patients with extranodal disease was significantly higher than that of the patients who had only nodal disease (25±12 vs. 15.3±10 respectively, p=0.001). SUVmax significantly correlated with IPI scores; the average SUVmax was significantly correlated with the IPI: Mean SUVmax of the predominant lesion was 13.9±9.5 in patients with low risk (IPI=0-1), 14.2±8.8 in low-intermediate risk group (IPI=2) whereas 26.6±9.5 in high-intermediate risk group (IPI=3) and 25±13.6 in high risk group patients (IPI=4-5) (p=0.002). SUVmax was not correlated with clinical stage, the number of extranodal sites and serum LDH levels. FDG uptake correlates with IPI and the presence of extranodal involvement in DLBCL. PET is a powerful method to detect extranodal disease in DLBCL. The correlation of SUVmax with these prognostic factors may highlight the importance of pretreatment FDG uptake as a metabolic marker of poor prognosis for patients with DLBCL.

    Full Text Available Malignant bone lymphomas are uncommonly encountered clinically. Men, 77-years-old, was admitted to hospital because of pain in the left shoulder. After imaging and histological examination diagnosed primary bone lymphoma. Primary lymphoma of the bone is an extranodal lymphoma that arises from the medullary cavity and manifests as a localized, solitary lesion, which represents 1% of all malignant lymphomas.

    Diffuse large B-cell lymphoma is the most common type of non-Hodgkin's lymphoma. More than 50% of patients have some site of extra-nodal involvement at diagnosis,including the gastrointestinal tract and bone marrow.However, a diffuse large B-cell lymphoma presenting as acute pancreatitis is rare. A 57-year-old female presented with abdominal pain and matted lymph nodes in her axilla. She was admitted with a diagnosis of acute pancreatitis. Abdominal computed tomography (CT) scan showed diffusely enlarged pancreas due to infiltrative neoplasm and peripancreatic lymphadenopathy. Biopsy of the axillary mass revealed a large B-cell lymphoma.The patient was classified as stage Ⅳ, based on the Ann Arbor Classification, and as having a high-risk lymphoma,based on the International Prognostic Index. She was started on chemotherapy with CHOP (cyclophosphamide,doxorubicin, vincristine and prednisone). Within a week after chemotherapy, the patient's abdominal pain resolved. Follow-up CT scan of the abdomen revealed a marked decrease in the size of the pancreas and peripancreatic lymphadenopathy. A literature search revealed only seven cases of primary involvement of the pancreas in B-cell lymphoma presenting as acute pancreatitis. However, only one case of secondary pancreatic involvement by B-cell lymphoma presenting as acute pancreatitis has been published. Our case appears to be the second report of such a manifestation.Both cases responded well to chemotherapy.

    Full Text Available Abstract Background To describe a rare manifestation of mantle cell lymphoma (MCL in conjunctiva, with clinical, hisologic, immunohistologic and genetic findings together with review of the Literature. Case presentation Most ocular adnexal lymphomas are extranodal marginal zone B-cell lymphomas of mucosa-associated lymphoid tissue (MALT. A few cases of ocular adnexal mantle cell lymphomas have been reported in the literature. We present a case of mantle cell lymphoma presenting as right conjunctival mass of at least three months duration in a 64-year-old man. Histopathologic examination showed a proliferation of monomorphous small-to-medium-sized lymphoid cells with cleaved nuclei in the subconjunctiva. By immunohistochemistry, the infiltrate was positive for CD20, CD5, BCL-2, cyclin D1, and the transcription factor SOX11. Fluorescent in situ hybridization demonstrated the presence of IGH-CCND1 fusion indicating t(11;14. Conclusion A rigorous approach to initial diagnosis and staging of small cell lymphomas of the ocular adnexa is needed. The recognition of ocular MCL requires appropriate immunohistochemical staining and/or genetic confirmation to differentiate this rare form of presentation of MCL from other more frequent small cell lymphomas.

    Full Text Available Objective: Our aim was evaluate the role the PET/CT in the assessment of response to therapy in patients with Non-Hodgkin extra-nodal lymphoma: in particular, a five-point scale (Deauville criteria, which can be employed for early- and late-therapeutic response assessment. Methods: Sixty patients with pathologically confirmed Non-Hodgkin lymphoma (NHL were enrolled in this prospective study. All patients underwent the following PET/CT examinations: initial PET/CT for staging, interim PET/CT and end of treatment PET/CT. Response assessment was done using new Cheson’s guidelines and five-point scale (Deauville criteria. Results: All patients were evaluated for response to therapy in the early interim, followed by late interim, as well as end treatment assessment for the overall response. We found good concordance of response assessment according to the Deauville criteria classification with International Harmonization Project (IHP classification. After early interim 48/60 patients had concordant designations (91.7%, 83.3%, 70%, and 33.3% and 12 patients had discordant designations. After late interim, 56/60 patients had concordant designations (100%, 100%, 80%, and 50% and four patients had discordant designations. After end of treatment, 54/60 patients had concordant designations (100%, 100% and 71.4% and six patients has discordant designations. Conclusion: Response assessment according to the Deauville criteria classification showed good concordance with IHP classification. According to our findings, we recommend the use of Deauville criteria in reporting of PET/CT for staging and assessment of response to treatment.

    2018-01-01

    Full Text Available Intravascular large B-cell lymphoma is a rare subtype of extranodal diffuse B-cell lymphoma characterized by proliferation of neoplastic cells within the lumen of small and medium sized vessels. Clinical and imaging findings are nebulous as the intravascular subtype of lymphoma can involve a multitude of organs. Involvement of the gallbladder is extremely uncommon, and imaging findings can be easily confused for more prevalent pathologies. We report a case of intravascular large B-cell lymphoma in an 83-year-old male and review clinical presentation and imaging findings on CT, ultrasound, hepatobiliary iminodiacetic acid (HIDA scan, and MRI. It is important for the radiologist to know about this disease as the imaging findings are atypical of other types of lymphoma, and this may lead to a delay in diagnosis and treatment.

    Full Text Available Abstract Background Primary thyroid gland lymphomas are uncommon tumours that occur in the setting of lymphocytic thyroiditis or Hashimoto's disease in almost all cases. In this condition a distinction between an inflammatory lymphoid infiltrate and a low grade lymphoma may be extremely difficult and precise criteria are necessary for a correct diagnosis. Patient and methods We report a case of a minute focus of primary extranodal marginal zone B-cell lymphoma (EMZBCL, incidentally discovered in a 63-year-old man with Hashimoto thyroiditis (HT and diagnosed by means of polymerase chain reaction (PCR after laser capture microdissection. The histological examination of surgical specimen confirmed the diagnosis of HT and showed a minute focus of dense lymphoid infiltrate (less than 4 mm in diameter, composed by centrocyte-like cells forming MALT balls. Immunoistochemistry was not useful. A microscopic focus of EMZBCL was suspected on the basis of morphological features. PCR assays revealed the rearrangement of the heavy chain of immunoglobulins only in the microdissected suspicious area, confirming the diagnosis of EMZBCL. Conclusion Our finding suggests that in cases of autoimmune thyroiditis a careful examination of the thyroid specimen is warranted, in order to disclose areas or small foci of lymphomatous transformation. Furthermore, in difficult cases with doubtful immunohistological findings, ancillary techniques, such as molecular studies, are necessary for a conclusive diagnosis.

    Burkitt lymphoma, is described as an aggressive form of non-Hodgkin lymphoma of B cells which occurs most often in children and young adults, ovarian lymphoma can appear as a primary lesion or more commonly referred to as a metastasis. Primary ovarian lesions are rare manifestations corresponding to 0.5% of non-Hodgkin lymphoma and 1.5% of ovarian tumors. Clinic case: 31 years old female with general weakness, march incapacity, dyspnea, hyporexia, fever, diaphoresis, weight loss of 20 kg, flat abs with abdominal pain; Ca125 610 U/ml. Abdominal computed tomography shows a solid aspect tumor which affects the right pelvic cavity. Bilateral ovarian tumors were removed. Microscopically, both lesions show a "starry sky" pattern composed by a monotonous infiltration of lymphocytes mixed with large and clear macrophages, several atypical mitoses, and necrosis and hemorrhage areas. Immunohistochemistry was positive for CD10, CD20, and negative for CD3 and high Ki67 proliferation index. Bilateral ovarian Burkitt's lymphoma was diagnosed. Bilateral ovarian Burkitt's lymphoma is a rare entity, with a variability of presentations, the abdominal pain and abdominal tumors are the most frequent. The patient's prognosis at short term is poor, therefore it's necessary to know this entity and make an early diagnosis.

    Full Text Available Herein reported is an extremely rare case of primary MALT lymphoma of cerebral parenchyma. A 79-year-old man presented with paresis. Imaging modalities identified a tumor measuring 3 cm in diameter in right cerebral parenchyma. An operation completely resected the tumor. Macroscopically, the tumor was well defined, but showed mild infiltrative features. Histologically, the tumor showed proliferation of small atypical lymphocytes separated by fibrous septae with AL amyloid depositions. No apparent plasma cell differentiation was seen. The tumor cells showed monotonous appearances with hyperchromatic nuclei but without nucleoli and nuclear indentations. Immunoblastic cells were scattered. Immunohistochemically, tumor cells were positive for vimentin, CD45, CD20, CD79α, bcl-2, CD3 (focal, CD45RO (focal, CD5 (focal, CD10, CD23, bcl-6, CD138, p53, and Ki-67 (labeling = 27%. The immunoblastic cells were positive for CD30. The lymphoid cells were negative for Epstein–Barr virus (EBV-related molecules of EBV latent membrane protein-1 (LMP-1 and EBV early RNAs (EBER. They were also negative for cytokeratins AE 1/3 and CAM5.2, cyclin D1, CD34, GFAP, α-smooth muscle actin, and S100 protein. Because of the heterogeneity of tumor cells and positive AL amyloid deposition, the author diagnosed it as primary MALT lymphoma. The patient is now free from tumors. Differential diagnosis was discussed.

    The prognostic significance of ABO blood type for lymphoma is largely unknown. We evaluated the prognostic role of ABO blood type in patients with extranodal natural killer (NK)/T-cell lymphoma (ENKTL). We retrospectively analyzed clinical data of 697 patients with newly diagnosed ENKTL from three cancer centers. The prognostic value of ABO blood type was evaluated using Kaplan-Meier curves and Cox proportional hazard models. The prognostic values of the International Prognostic Index (IPI) and the Korean Prognostic Index (KPI) were also evaluated. Compared with patients with blood type O, those with blood type non-O tended to display elevated baseline serum C-reactive protein levels (P = 0.038), lower rate of complete remission (P = 0.005), shorter progression-free survival (PFS, P 60 years (P KPI in distinguishing between the intermediate-to-low- and high-to-intermediate-risk groups. ABO blood type was an independent predictor of clinical outcome for patients with ENKTL.

    CXCR4 belongs to the family of chemokine receptors. Together with its sole known ligand CXCL12 (SDF-1alpha), it has a pivotal role during organogenesis and for homing of hematopoietic stem cells. CXCR4 is overexpressed in various malignancies, and this is often associated with poor prognosis. Therefore, molecular imaging of CXCR4 bears a great potential for diagnostics and selecting patients for CXCR4-directed therapies. The CXCR4-directed positron emission tomography (PET) tracer [ 68 Ga]Pentixafor has been shown to visualize CXCR4 expression in various malignancies in vivo. Whereas this tracer has limitations compared to 18 F-Fluorodeoxyglucose ([ 18 F]FDG) in diagnostic PET imaging in peripheral tumour lesions, it might add valuable information in routine diagnostics and response assessment of tumours in close proximity to the central nervous system (CNS) and malignancies within this organ. As a proof-of-concept, we performed [ 68 Ga]Pentixafor PET imaging in a patient with extranodal marginal zone lymphoma (MZL) of the orbital cavities at diagnosis and for post-therapy response assessment. Compared to routinely conducted [ 18 F]FDG PET, the lymphoma lesions determined by magnetic resonance imaging (MRI) showed high tracer accumulation at diagnosis, which decreased upon treatment. We therefore propose that imaging of CXCR4 with [ 68 Ga]Pentixafor is a potential diagnostic tool for tumours close to or within the CNS and suggest this being studied in clinical trials.

    Full Text Available A 64-year old woman with a long standing Sjogren’s syndrome was undergoing evaluation for renal transplant surgery when two pulmonary opacities were detected on chest CT. Subsequent biopsy revealed extranodal marginal B-cell non-Hodgkin’s lymphoma (NHL. An FDG-PET/CT scan was then performed which demonstrated isolated FDG avid pulmonary involvement. After therapy, FDG-PET/CT scans showed good response to treatment with near complete resolution of FDG avidity. This rare case illustrates the rare pulmonary manifestation of extranodal lymphoma in a patient with Sjogren’s syndrome and emphasizes the value of FDG PET/CT in the initial staging and evaluation of response to treatment, which has not previously been published.

    Neoplasm is an uncommon cause of a parkinsonian syndrome. We report a woman with primary brain B-cell lymphoma presenting as Parkinson's disease. After 1 year of the illness, CT and MRI showed lesions without mass effect in the basal ganglia and corpus callosum. The patient did not respond to levodopa and right cerebellar and brain-stem signs appeared, which prompted further neuroimaging, showing an increase in size of the lesions and a right cerebellar and pontine mass. Stereotactic biopsy of the basal ganglia showed high-grade B-cell lymphoma. Despite the basal ganglia frequently being involved in lymphoma of the brain, presentation with typical or atypical parkinsonism is exceptional. (orig.)

    2018-01-01

    Full Text Available Case summary A 9-year-old spayed female domestic shorthair cat with clinical signs suggestive of chronic recurrent otitis media and recent seizures was presented with multifocal nervous system disease, including bilateral central and/or peripheral vestibular, cerebellar and forebrain deficits. Prior to presentation, there was inadequate improvement after 6 weeks of treatment for bilateral middle ear effusion from which a highly susceptible Staphylococcus species was cultured. This was followed by the development of seizures. Results of a complete blood count and serum chemistry were unremarkable, and a previous feline leukemia virus/feline immunodeficiency virus ELISA was negative. The cat was hospitalized overnight and had multiple seizures. The following morning the cat’s mentation worsened, and the cat lost ventilatory drive after induction for anesthesia in preparation for MRI. A brain herniation event was suspected, and the cat was euthanized prior to further diagnostics. On post-mortem examination both tympanic bullae were filled with a soft, tan-colored material. Histologically, this material was composed of neoplastic lymphocytes. In addition, neoplastic lymphocytes were found in the leptomeninges, brain parenchyma, submandibular lymph nodes and pancreas. The neoplastic lymphocytes were negative for both B- and T-lymphocyte immunohistochemical markers and PCR for antigen receptor rearrangements failed to amplify target DNA, indicating non-B, non-T-cell lymphoma. Relevance and novel information To our knowledge, this is the first report of lymphoma with confirmed bilateral tympanic bulla involvement in the human and veterinary literature. Neoplasia should be considered in cases of middle-ear effusion that do not improve adequately with appropriate antimicrobial therapy.

    2015-01-01

    Purpose: To report the long-term outcome and patterns of relapse of a large cohort of marginal zone lymphoma (MZL) patients treated with curative-intent radiation therapy (RT) alone. Patients and Methods: We reviewed the charts of 490 consecutive patients with stage IE or IIE MZL referred between 1992 and 2012 to our institution. Of those, 244 patients (50%) were treated with RT alone. Pathology was confirmed by hematopathologists at our institution. Patient and disease factors were analyzed for association with relapse-free survival (RFS) and overall survival (OS). Results: Median age of the cohort was 59 years, and median follow-up was 5.2 years. Ann Arbor stage was IE in 92%. Most common disease sites were stomach (50%), orbit (18%), non-thyroid head-and-neck (8%), skin (8%), and breast (5%). Median RT dose was 30 Gy. Five-year OS and RFS were 92% and 74%, respectively. Cumulative incidence of disease-specific death was just 1.1% by 5 years. Sixty patients (24%) developed relapse of disease; 10 were in the RT field. Crude rate of transformation to pathologically confirmed large-cell lymphoma was 1.6%. On multivariable analysis, primary disease site (P=.007) was independently associated with RFS, along with age (P=.04), presence of B-symptoms (P=.02), and International Prognostic Index risk group (P=.03). All disease sites except for head-and-neck had worse RFS relative to stomach. Conclusion: Overall and cause-specific survival are high in early-stage extra-nodal MZL treated with curative RT alone. In this large cohort of 244 patients, most patients did not experience relapse of MZL after curative RT; when relapses did occur, the majority were in distant sites. Stomach cases were less likely to relapse than other anatomic sites. Transformation to large-cell lymphoma was rare

    Full Text Available Burkitt's lymphoma is an extremely aggressive B-cell non-Hodgkin lymphoma. Patients with the sporadic form of Burkitt's lymphoma typically present with a rapidly growing abdominal mass, pain and distension. Involvement of either the appendix and/or ovaries in females is a rare manifestation of the disease. We present an unusual case of a 13 year old girl with appendiceal and ovarian Burkitt's lymphoma presenting with signs of acute appendicitis. This case demonstrates the potential for secondary involvement of the appendix and/or ovaries from Burkitt's lymphoma as well as the importance of the histopathology.

  4. Tanzanian malignant lymphomas: WHO classification, presentation, ploidy, proliferation and HIV/EBV association

    Science.gov (United States)

    2010-01-01

    Background In Tanzania, the International Working Formulation [WF] rather than the WHO Classification is still being used in diagnosing malignant lymphomas (ML) and the biological characterization including the HIV/EBV association is sketchy, thus restraining comparison, prognostication and application of established therapeutic protocols. Methods Archival, diagnostic ML biopsies (N = 336), available sera (N = 35) screened by ELISA for HIV antibodies and corresponding clinical/histological reports at Muhimbili National Hospital (MNH) in Tanzania between 1996 and 2006 were retrieved and evaluated. A fraction (N = 174) were analyzed by histopathology and immunohistochemistry (IHC). Selected biopsies were characterized by flow-cytometry (FC) for DNA ploidy (N = 60) and some by in-situ hybridization (ISH) for EBV-encoded RNA (EBER, N = 37). Results A third (38.8%, 109/281) of the ML patients with available clinical information had extranodal disease presentation. A total of 158 out of 174 biopsies selected for immunophenotyping were confirmed to be ML which were mostly (84. 8%, 134/158) non-Hodgkin lymphoma (NHL). Most (83.6%, 112/134) of NHL were B-cell lymphomas (BCL) (CD20+), of which 50.9%, (57/112) were diffuse large B-cell (DLBCL). Out of the 158 confirmed MLs, 22 (13.9%) were T-cell [CD3+] lymphomas (TCL) and 24 (15.2%) were Hodgkin lymphomas (HL) [CD30+]. Furthermore, out of the 60 FC analyzed ML cases, 27 (M:F ratio 2:1) were DLBCL, a slight majority (55.6%, 15/27) with activated B-cell like (ABC) and 45% (12/27) with germinal center B-cell like (GCB) immunophenotype. Overall, 40% (24/60) ML were aneuploid mostly (63.0%, 17/27) the DLBCL and TCL (54.5%, 6/11). DNA index (DI) of FC-analyzed ML ranged from 1.103-2.407 (median = 1.51) and most (75.0%) aneuploid cases showed high (>40%) cell proliferation by Ki-67 reactivity. The majority (51.4%, 19/37) of EBER ISH analyzed lymphoma biopsies were positive. Of the serologically tested MLs, 40.0% (14/35) were HIV

    Full Text Available Primary non-Hodgkin’s lymphoma (NHL can arise from lymphatic cells located in solid organs (extranodal and it accounts for 25 to 35% of all NHL. Primary lymphoma on the female genital tract (PLFGT is a rare disease, comprising 0.2 to 1.1% of all extranodal lymphomas in the female population. In this paper, the authors report an extremely rare case of a 48-year-old woman who exhibited an abnormal uterine bleeding, pelvic pain, and dysmenorrhea history. The transvaginal ultrasound showed an anteverted uterus measuring 153 cm3 in volume, with intramural leiomyomas. She underwent a total laparoscopic hysterectomy with bilateral salpingectomy. The histologic evaluation of the specimen showed a follicular lymphoma with diffuse pattern in the endometrium. This report illustrates the difficulty in the diagnosis of primary lymphomas of the female genital tract.

    This study analysed incidence, patient outcome, immunophenotype and prognostic factors of histological transformation (HT) from extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) to diffuse large B-cell lymphoma (DLBCL) in 467 patients (median age, 61 years). The primary sites of MALT lymphoma were the stomach (43%), ocular adnexa (25%), lung (8%), systemic (8%) and other tissues (16%). HT occurred in 8% of MALT lymphomas. Risk of HT by 15 years was 5%: 4% in limited-stage diseases (n = 385) and 16% in advanced-stage diseases (n = 56) (P = 0·02). The median time to HT was 48 months (range, 4-139). Five-year progression-free survival (PFS) and overall survival (OS) rates after HT were 80% and 94%, respectively. Immunohistochemical results of DLBCL were as follows: germinal centre B-cell (GCB)/non-GCB, 37%/63%; CD10, 9%; BCL6, 59%; MUM1, 38%; MYC, 42%; BCL2, 35%; Ki67 ≥ 90%, 23%; and CD5, 3%. The majority (75%, 9/12) of GCB-type DLBCLs exhibited CD10(-) , BCL6(+) and MUM1(-) immunophenotypes; the remainder had CD10(+) immunophenotypes. Multivariate analysis revealed that only advanced stage at HT was a significant adverse factor for PFS (P = 0·037). Thus, overall risk of HT was low and prognosis after HT was favourable; however, in advanced-stage cases, risk of HT was relatively high and prognosis was unfavourable. © 2016 John Wiley & Sons Ltd.

    Primary extranodal lymphoma is known to occur in nose, gastrointestinal tract, skin, bone, and central nervous system. However, it is extremely rare for primary lymphoma to arise in skeletal muscle. We report a case of a 32-year-old man who presented initially with fever and fatigue. He had a history of alcohol abuse. Laboratory studies and computerized tomography scan showed results consistent with rhabdomyolysis, but the cause of the rhabdomyolysis was undetermined. After biopsy of abdominal skeletal muscle with histologic examination and T-cell receptor gamma chain gene rearrangement analysis, the diagnosis of peripheral T-cell lymphoma was established. After two cycles of the cyclophosphamide, doxorubicin, vincristine, prednisone, and etoposide regimen, the patient's symptoms greatly improved. This is the third reported case of peripheral T-cell lymphoma arising in skeletal muscle reported in the literature and which presented clinically with rhabdomyolysis. The alcohol abuse during the clinical course likely worsens the pathologic process of the rhabdomyolysis. Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

    The role of (18)Fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) in extranodal natural killer/T-cell lymphoma (ENKL) is not well established. This study aimed to investigate the prognostic role of the pretreatment maximum standardized uptake value (SUV(max)) on PET/CT in patients with newly diagnosed ENKL. Among 364 consecutive patients with newly diagnosed ENKL, 81 patients were included and reviewed. The impact of SUV(max) on survival and the relationship between SUV(max) and other clinicopathological parameters were analyzed. The median SUV(max) was 14.6 (range 2.0-45.4). The optimal cutoff value of SUV(max) to predict overall survival (OS) was 15. Patients with high SUV(max) (SUVmax >15) were associated with bulky disease (P KPI, P = 0.046), resistance to primary treatment (P = 0.014), poor OS (P 60 years (P = 0.001), stage III-IV (P = 0.023), SUV(max) >15 (P = 0.020), and bulky disease (>5 cm) (P = 0.002). By using the SUV(max), patients in most subgroups stratified by the KPI or the International Prognostic Index (IPI) were further discriminated in OS with significant statistical difference. Our results suggest the pretreatment SUV(max) is predictive of prognosis in patients with newly diagnosed ENKL. The SUV(max) may provide additional prognostic information for IPI and KPI.

    Extranodal natural killer (NK)/T cell lymphoma, nasal type (ENKTL) is an aggressive non-Hodgkin lymphoma and the majority of ENKTL cases are diagnosed at the localized stage. Radiotherapy in combination with chemotherapy has been used for localized ENKTL, but the optimal combination treatment modality and the best first-line chemotherapy regimen have not been defined. In this retrospective study, 44 patients with newly diagnosed, stages I/II ENKTL were enrolled and received intensity-modulated radiation therapy (IMRT, 50-56 Gy) followed by GDP (gemcitabine, dexamethasone, and cisplatin) chemotherapy. The median number of chemotherapy cycles per patient was 4 (range, 2-6 cycles). At the end of treatment, the overall response rate was 95% (42/44), including 39 patients (89%) who attained complete response. Two patients developed systemic progression after IMRT. With a median follow-up of 37.5 months, the 3-year overall survival (OS) rate and progression-free survival (PFS) rate were 85% (95% CI, 74 to 96%) and 77% (95% CI, 64 to 91%), respectively. Locoregional and systemic failure rates for this treatment were 9% (4/44) and 14% (6/44), respectively. The most common grades 3 to 4 adverse events included leukopenia (37%), neutropenia (34%), and mucositis (25%). No treatment-related deaths were observed. This study suggested high efficacy and low toxicity of IMRT followed by GDP regimen chemotherapy for newly diagnosed stage I/II ENKTL patients. These results require further investigation in prospective trials.

    C-reactive protein (CRP) is a biomarker of the inflammatory response, and it shows significant prognostic value for several types of solid tumors. The prognostic significance of CRP for lymphoma has not been fully examined. We evaluated the prognostic role of baseline serum CRP levels in patients with extranodal natural killer (NK)/T-cell lymphoma (ENKTL). We retrospectively analyzed 185 patients with newly diagnosed ENKTL. The prognostic value of the serum CRP level was evaluated for the low-CRP group (CRP≤10 mg/L) versus the high-CRP group (CRP>10 mg/L). The prognostic value of the International Prognostic Index (IPI) and the Korean Prognostic Index (KPI) were evaluated and compared with the newly developed prognostic model. Patients in the high-CRP group tended to display increased adverse clinical characteristics, lower rates of complete remission (P60 years, hypoalbuminemia, and elevated lactate dehydrogenase levels were independent adverse predictors of OS. Based on these four independent predictors, we constructed a new prognostic model that identified 4 groups with varying OS: group 1, no adverse factors; group 2, 1 factor; group 3, 2 factors; and group 4, 3 or 4 factors (PKPI in distinguishing between the low- and intermediate-low-risk groups, the intermediate-low- and high-intermediate-risk groups, and the high-intermediate- and high-risk groups. Our results suggest that pretreatment serum CRP levels represent an independent predictor of clinical outcome for patients with ENKTL. The prognostic value of the new prognostic model is superior to both IPI and KPI.

    We retrospectively enrolled 191 nasal-type, extranodal natural killer/T-cell lymphoma (ENKTL) patients newly diagnosed from 2008 to 2016 at the Sichuan Cancer Hospital, in order to evaluate the relationship between disease outcomes, demographic and clinical factors, and red blood cell distribution width (RDW). C-index, fisher's exact test, univariate analysis, and cox regression analysis were applied. The median age of patients was 44 years and 134 (70%) were men. The cutoff of RDW was 46.2 fL determined by Cutoff Finder. Patients with RDW≤46.2 fL had significantly better progression-free survival (PFS) (3-year PFS, 80.4% vs. 63.1%; P =0.01) and overall survival (OS) (3-year OS, 83.2% vs. 65.5%; P =0.004) than those with RDW>46.2 fL. Multivariate analysis demonstrated that elevated RDW is an independent adverse predictor of OS ( P =0.021, HR=2.04). RDW is an independent predictor of survival outcomes in ENKTL, which we found to be superior to both the prognostic index of natural killer lymphoma (PINK) and the Korean Prognostic Index (KPI) in discriminating patients with different outcomes in low-risk and high-risk groups (all P KPI, and PINK showed more powerful prognostic value than corresponding original models. RDW represents an easily available and inexpensive marker for risk stratification in patients with ENKTL treated with radiotherapy-based treatment. Further prospective studies are warranted to confirm the prognostic value of RDW in ENKTL.

    Full Text Available 6q21 genetic deletion has been frequently detected in extranodal NK/T cell lymphoma, nasal type (EN-NK/T-NT, and PRDM1 is considered as candidate gene. However, direct detection of PRDM1 deletion has not been well documented. We investigated genetic alterations of 6q21 and PRDM1 in 43 cases of EN-NK/T-NT and cell lines by FISH. PRDM1 expression was evaluated by immunohistochemistry and Western blot. The correlation between genetic alteration and PRDM1 expression and the significance in clinic-pathologic were analyzed. Heterozygous deletion of 6q21 and/or PRDM1 was observed in 24 of 43 cases (55.81% of EN-NK/T-NT including 16 cases (37.21% for 6q21 deletion and 19 cases (44.19% for PRDM1 deletion. Similarly, heterozygous codeletion of 6q21 and PRDM1 was identified in NK92 and NKL cells. The heterozygous deletion of 6q21 and/or PRDM1 was correlated with PRDM1 expression. However, genetic deletion of 6q21 and/or PRDM1 was not correlated with clinicopathological features of EN-NK/T-NT, while PRDM1 expression showed positive effect on the outcome of patients as those as disease site, B symptom, and clinical stage. Thus, heterozygous deletion of 6q21 and/or PRDM1 was frequently detected in EN-NK/T-NT and correlated with downregulation of PRDM1. But the prognostic role of genetic deletion needs to be further evaluated in larger cohort.

    On the basis of the benefits of frontline radiation in early-stage, extranodal natural killer (NK)/T-cell lymphoma (ENKTL), we conducted the trial of concurrent chemoradiotherapy (CCRT) followed by three cycles of gemcitabine, dexamethasone and cisplatin (GDP). Thirty-two patients with newly diagnosed, stage IE to IIE, nasal ENKTL received CCRT (that is, all patients received intensity-modulated radiotherapy 56 Gy and cisplatin 30 mg/m(2) weekly, 3-5 weeks). Three cycles of GDP (gemcitabine 1000 mg/m(2) intravenously (i.v.) on days 1 and 8, dexamethasone 40 mg orally on days 1-4 and cisplatin 75 mg/m(2) i.v. on day 1 (GDP), every 21 days as an outpatient were scheduled after CCRT. All patients completed CCRT, which resulted in 100% response that included 24 complete responses (CRs) and eight partial responses. The CR rate after CCRT was 75.0% (that is, 24 of 32 responses). Twenty-eight of the 32 patients completed the planned three cycles of GDP, whereas four patients did not because they withdrew (n = 1) or because they had an infection (n = 3). The overall response rate and the CR rate were 90.6% (that is, 29 of 32 responses) and 84.4% (that is, 27 of 32 responses), respectively. Only two patient experienced grade 3 toxicity during CCRT (nausea), whereas 13 of the 30 patients experienced grade 4 neutropenia. The estimated 3-year overall survival and progression-free rates were 87.50% and 84.38%, respectively. In conclusion, CCRT followed by GDP chemotherapy can be a feasible and effective treatment strategy for stage IE to IIE nasal ENKTL.

    Although flow cytometry (FCM) is used to evaluate cell surface markers of various leucocyte populations quantitatively, little is known about the usefulness of FCM in lymphoproliferative disorders of the ocular adnexa. The aim of this study was to disclose results of FCM, which were compared among IgG4-related ophthalmic disease (IgG4-ROD), idiopathic orbital inflammation (IOI), and extranodal marginal zone B-cell lymphoma (EMZL). This is a retrospective observational study. Sixty-nine tumors comprising of 16 IgG4-ROD, 24 IOI, and 29 EMZL were enrolled in the study. All tumors, surgically excised, were diagnosed based on histopathology, immunoglobulin (Ig) heavy chain gene rearrangement, and FCM. In FCM, the percentage of T-cell markers (CD2, CD3, CD4, CD5, CD7, CD8), B-cell markers (CD10, CD19, CD20, CD23), NK cell marker (CD56) and cell surface kappa/lambda was searched based on medical records. Ig light chain restriction was evaluated from results in kappa/lambda deviation by FCM. The percentage of CD2, CD3, CD4, CD7, and CD10 was significantly higher in IgG4-ROD/IOI than EMZL (pIgG4-ROD/IOI (pIgG4-ROD and IOI. Kappa-positive cells were significantly greater in EMZL than IgG4-ROD/IOI (pIgG4-ROD/IOI and false-negative was observed in 10 (34.5%) EMZL cases. Sensitivity and specificity of Ig light chain restriction were 65.5 and 92.5%, respectively. Analyses of cell surface markers using FCM were useful in differentiating EMZL from IgG4-ROD/IOI. Sensitivity of Ig light chain restriction was relatively low in diagnosis of EMZL using FCM. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

    The aim of this study was to determine whether maximum standardized uptake value (SUVmax), whole-body metabolic tumour volume (WBMTV), and whole-body total lesion glycolysis (WBTLG) measured on pretreatment {sup 18}F-FDG PET/CT can predict prognosis in patients with extranodal natural killer/T-cell lymphoma (ENKTL). We conducted a retrospective analysis of 20 patients with newly-diagnosed ENKTL who underwent pretreatment {sup 18}F-FDG PET/CT. WBMTV and WBTLG were measured automatically using the boundaries of voxels presenting SUV > 3.0. Uni- and multivariate analyses for survival and disease progression were performed using clinical variables and PET parameters (SUVmax, WBMTV, and WBTLG). During the follow-up period (median 26.3 months), 12 patients showed disease progression and 10 patients died from the disease. Receiver operating characteristic curve analysis showed cut-off values for SUVmax, WBMTV and WBTLG of 8.1, 14.4 cm{sup 3} and 52.7, respectively. Univariate analysis showed that the International Prognostic Index (IPI) score and PET parameters were significant predictors of overall survival (OS) and progression-free survival (PFS). Multivariate analysis, even after adjustment for the IPI score, showed that high WBMTV was the best predictor of OS and PFS, and high SUVmax and WBTLG were significant predictors of PFS. Our results suggested that the use of PET parameters together with the IPI score may be useful for detailed prediction of prognosis in ENKTL patients. Therefore, despite a lower IPI score, patients with high PET parameter values might be considered candidates for aggressive therapy to improve clinical outcomes. (orig.)

    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.

    Full Text Available Abstract Background In Tanzania, the International Working Formulation [WF] rather than the WHO Classification is still being used in diagnosing malignant lymphomas (ML and the biological characterization including the HIV/EBV association is sketchy, thus restraining comparison, prognostication and application of established therapeutic protocols. Methods Archival, diagnostic ML biopsies (N = 336, available sera (N = 35 screened by ELISA for HIV antibodies and corresponding clinical/histological reports at Muhimbili National Hospital (MNH in Tanzania between 1996 and 2006 were retrieved and evaluated. A fraction (N = 174 were analyzed by histopathology and immunohistochemistry (IHC. Selected biopsies were characterized by flow-cytometry (FC for DNA ploidy (N = 60 and some by in-situ hybridization (ISH for EBV-encoded RNA (EBER, N = 37. Results A third (38.8%, 109/281 of the ML patients with available clinical information had extranodal disease presentation. A total of 158 out of 174 biopsies selected for immunophenotyping were confirmed to be ML which were mostly (84. 8%, 134/158 non-Hodgkin lymphoma (NHL. Most (83.6%, 112/134 of NHL were B-cell lymphomas (BCL (CD20+, of which 50.9%, (57/112 were diffuse large B-cell (DLBCL.

    This study aimed to clarify the benefit of radiotherapy (RT) in patients with early-stage extranodal NK/T-cell lymphoma (NKTCL) who achieve a complete response (CR) after asparaginase-containing chemotherapy (CT). Of 240 patients achieved a CR after asparaginase-containing CT, 202 patients received additional RT (CT + RT), and 38 patients did not (CT alone). Compared to CT alone, CT + RT significantly improved overall survival (OS), disease-free survival (DFS) and locoregional control (LRC). The 5-year OS, DFS and LRC rates were 84.9%, 76.2% and 84.9% for CT + RT, compared to 58.9% (P = 0.006), 43.6% (P = 0.001) and 62.1% (P = 0.026) for CT alone. The 5-year cumulative disease recurrence rate was 18.8% for CT + RT compared to 46.9% (P = 0.003) for CT alone. High-dose RT (≥50 Gy) significantly decreased the risk of locoregional recurrence. The 5-year cumulative locoregional failure rate was 35.5% for patients receiving <50 Gy compared to 8.8% for patients receiving ≥50 Gy (P = 0.028). For patients with early-stage NKTCL who achieve a CR after asparaginase-containing CT, omission of RT results in frequent locoregional recurrence and a poor prognosis; RT is essential to improve locoregional control and survival.

    Lymphoma of the eyelid constitutes 5% of ocular adnexal lymphoma. In previously published cases, 56% of lymphomas of the eyelid are of B-cell origin and 44% are of T-cell origin. The most frequent B-cell lymphomas are extranodal marginal zone lymphoma (27 cases-14%) and diffuse large B......-cell lymphoma (18 cases-9%). T-cell lymphomas are most frequently mycosis fungoides (25 cases-13%), extranodal natural killer/T-cell, nasal-type lymphoma (12 cases-6%), and primary cutaneous anaplastic large-cell lymphoma (12 cases-6%). This distribution differs from the distribution of ocular adnexal lymphoma...... and that of cutaneous lymphoma. The majority of subtypes occur in elderly patients, except for lymphoblastic lymphoma of B-cell and T-cell origin and Burkitt lymphoma, which occur in children and adolescents. Several subtypes have a male predominance, including peripheral T-cell lymphoma and Burkitt lymphoma. Only...

    2007-08-01

    We report the case of a previously healthy, 10-year-old boy who presented to the emergency department with a syncopal episode. In the emergency department, the patient was diagnosed with a right atrial mass, later identified as a precursor B-cell lymphoblastic lymphoma (LL). Most causes of syncope in children are not life threatening. In most cases, it indicates a predisposition to vasovagal episodes. Lymphomas account for approximately 7% of malignancies among children younger than 20 years, are more common in white males and immunocompromised patients, and are predominantly tumors of T-cell origin. Children with non-Hodgkin lymphoma usually present with extranodal disease, most frequently involving the abdomen (31%), mediastinum (26%), or head and neck (29%). Our patient was unique in that he was a nonimmunocompromised, black boy, presenting with syncope in the setting of a large atrial mass identified as a precursor B-cell LL.

    Full Text Available Primary thyroid lymphoma is a rare malignancy, representing 2-8% of all thyroid malignancies and 1-2% of all extranodal lymphomas. The majority of cases concern non-Hodgkin`s lymphoma of B cell origin, following by Hodgkin’s disease, T cell lymphomas and rarely marginal zone B-cell mucosa-associated lymphoid tissue (MALT lymphomas. MALT lymphomas have been associated with long-standing autoimmune Hashimoto`s thyroiditis. We present the case of a 44-years-old woman with thyroid MALT lymphoma in the background of multinodular goiter of autoimmune origin.

    A 66-year-old diabetic man presented with severe right thigh swelling and pain together with acute renal failure. At autopsy, this was found to be due to disseminated high grade B cell lymphoma invading the psoas muscle and multiple organs, including the kidneys. The unique presentation of this case emphasizes the need for increased awareness of the variety of ways in which lymphoma can manifest itself.

    Full Text Available Clitoromegaly is a clinical manifestation of various local and systemic conditions in all species. The external genitalia are a very rare site of primary or metastatic lymphoma in canines, with only one previously-reported case in a dog and only sparse reports in the medical literature. Lymphoma is also very rare in dogs less than four years of age. This account reports on a T-cell multicentric lymphoma in a 16-month-old Basset hound presented primarily for clitoromegaly. The patient survived for 68 days with cyclophosphamide-vincristine-prednisolone therapy. The causes of clitoromegaly in all species, including humans, are tabulated with references.

    Triple-hit lymphoma is a highly aggressive B-cell lymphoma. We report a case of triple-hit lymphoma transformed from systemic follicular lymphoma (FL) after 9-year remission and presented primarily as an isolated orbital mass without systemic symptoms or lymphadenopathy. A 58-year-old female presented with intermittent vertical binocular diplopia, left upper eyelid swelling and pain and was found to have a 2.9 cm orbital mass. Histological section revealed a CD10-positive large B-cell lymphoma, consistent with transformation of FL. Fluorescent in situ hybridization (FISH) analysis demonstrated rearrangements involving C-MYC, BCL-2 and BCL-6 genes, indicating a high grade, triple-hit lymphoma. Triple-hit lymphoma transformed from a low-grade lymphoma may initially present as an isolated orbital mass without systemic evidence of transformation. Early recognition of double or triple-hit lymphomas is important since these patients require aggressive chemotherapy.

    Full Text Available Though rare amongst stomach neoplasms, primary gastric diffuse large B cell lymphoma is one of the commonest extranodal non-Hodgkin lymphomas. If left untreated, it can have a devastating progression and life-threatening consequences. We present the case of a successfully treated large antral ulcer confirmed to be large B cell lymphoma as evidenced by radiologic, endoscopic and histopathologic findings. A brief discussion about the types of gastric lymphoma, their Helicobacter pylori relation and therapeutic modalities follows.

    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.

    This report describes a primary periosteal location of non-Hodgkin's lymphoma, without nodal disease, and without adjacent intramedullary disease at presentation. The clinical and imaging appearance of periosteal lymphoma simulates other neoplastic osseous surface tumors more than that of lymphoma in other locations. Consideration of this rare presentation of non-Hodgkin's lymphoma in the differential diagnosis of periosteal bone lesions can be helpful to ensure proper diagnosis and treatment. (orig.)

    2012-02-01

    Full Text Available OBJECTIVE: This paper aimed at studying presentations of the central nervous system (CNS lymphoma using structural images obtained by magnetic resonance imaging (MRI. METHODS: The MRI features at presentation of 15 patients diagnosed with CNS lymphoma in a university hospital, between January 1999 and March 2011, were analyzed by frequency and cross tabulation. RESULTS: All patients had supratentorial lesions; and four had infra- and supratentorial lesions. The signal intensity on T1 and T2 weighted images was predominantly hypo- or isointense. In the T2 weighted images, single lesions were associated with a hypointense signal component. Six patients presented necrosis, all of them showed perilesional abnormal white matter, nine had meningeal involvement, and five had subependymal spread. Subependymal spread and meningeal involvement tended to occur in younger patients. CONCLUSION: Presentations of lymphoma are very pleomorphic, but some of them should point to this diagnostic possibility.

    Full Text Available Abstract Background In female adolescents and young adults, malignancies of the genital tract are the most frequent type of cancer, closely followed by Hodgkin’s and non-Hodgkin’s lymphomas. Case Presentation We report an unusual case of sporadic Burkitt’s lymphoma (BL presenting with massive bilateral ovarian infiltration, peritoneal carcinomatosis and diffuse nodular lesions of the stomach and the intestine mimicking Krukenberg tumor. Diagnostic biopsies were obtained by endoscopy of the upper gastrointestinal tract. With intensive chemotherapy, complete remission was rapidly achieved, without life-threatening tumor lysis syndrome. Conclusion Besides metastatic gastric adenocarcinoma, BL is an important differential diagnosis in adolescents presenting with Krukenberg tumor.

    2013-01-01

    Full Text Available Primary intestinal lymphoma is a rare lymphoproliferative neoplasm of the small intestine. The primary nature is established on the basis of lack of evidence of lymphoma on chest X-ray, computerized tomographic scan, peripheral blood or bone marrow puncture. Tumor involvement is limited to the gastrointestinal tract, the criteria for inclusion are that the symptoms related to the small intestine are predominant or the only symptoms at the time of laparotomy. Hodgkin′s lymphoma (HL primarily in the small intestine is a rare entity and an uncommon presentation of the disease. Ileum is the more common site of infliction than the jejunum because of its abundant lymphoid follicles. Here, we present a case of primary intestinal HL, in a 30-year-old male.

    Non-Hodgkin lymphoblastic lymphomas are very uncommon tumors that rarely involve the heart; however, when they do, they typically cause cardiac symptoms. Herein, we describe the case of a young woman who presented with respiratory symptoms. These were caused by a high-grade lymphoblastic lymphoma, which originated in the left inferior pulmonary vein and extended into the left atrium. The tumor was surgically debulked, but it recurred in 1 month, and the patient underwent chemotherapy. Six months later, she had recurrent respiratory symptoms, and echocardiography revealed a persistent mass in the left lower lobar vein. A modified chemotherapy regimen led to complete resolution of the tumor within 2 months. We are unaware of other reports of a primary cardiac non-Hodgkin lymphoblastic lymphoma with this unusual site of origin and rare manifestation of symptoms. PMID:21841872

    Olszewski, Adam J., E-mail: adam_olszewski@brown.edu; Desai, Amrita

    2014-03-01

    Purpose: To determine the factors associated with the use of radiation therapy and associated survival outcomes in early-stage marginal zone lymphoma of the mucosa-associated lymphoid tissue (MALT). Methods and Materials: We extracted data on adult patients with stage I/II MALT lymphoma diagnoses between 1998 and 2010 recorded in the Surveillance, Epidemiology, and End Results (SEER) database. We studied factors associated with radiation therapy administration in a logistic regression model and described the cumulative incidence of lymphoma-related death (LRD) according to receipt of the treatment. The association of radiation therapy with survival was explored in multivariate models with adjustment for immortal time bias. Results: Of the 7774 identified patients, 36% received radiation therapy as part of the initial course of treatment. Older patients; black or Hispanic men; white, Hispanic, and black women; and socioeconomically disadvantaged and underinsured patients had a significantly lower chance of receiving radiation therapy. Radiation therapy administration was associated with a lower chance of LRD in most sites. In cutaneous, ocular, and salivary MALT lymphomas, the 5-year estimate of LRD after radiation therapy was 0%. The association of radiation therapy with overall survival in different lymphoma sites was heterogeneous, and statistically significant in cutaneous (hazard ratio 0.45, P=.009) and ocular (hazard ratio 0.47, P<.0001) locations after multivariate adjustment. Conclusions: Demographic factors are associated with the use of radiation therapy in MALT lymphoma. Clinicians should be sensitive to those disparities because the administration of radiation therapy may be associated with improved survival, particularly in cutaneous and ocular lymphomas.

    We conducted a retrospective study of 135 patients of stage IE/IIE extranodal natural killer/T cell lymphoma, nasal type (ENKTL) treated with CHOP as induction chemotherapy to find some valuable prognostic factors and analyze the usefulness of International Prognostic Index (IPI) and Korean Prognostic Index (KPI) in predicting prognosis. Most of the patients were in the low-risk group (IPI score 0-1). Complete remission (CR) after induction chemotherapy was achieved in 31.8 % of the patients, which increased to 69.6 % after radiotherapy. The 2-, 5-, and 10-year overall survival (OS) rates were 60, 48, and 43 %, respectively. Patients with better performance status (ECOG 0-1), normal serum LDH level, without local invasiveness, low KPI scores, and IPI score of 0 had significantly better overall survival (P KPI score systems should be improved further to classify patients into different groups, and should be validated in larger prospective trials. Due to the multi-drug resistance mechanism of ENKTL, CHOP is no longer the state of art and novel drugs should be incorporated into future treatments.

    The broad category of non-Hodgkin's lymphoma includes a large variety of different diseases including indolent as well as aggressive lymphomas. Mucosa-associated lymphoid tissue (MALT) lymphoma arises in the extranodal mucosal lymphoid tissue and has only been recognised as a distinct entity in recent years. It affects one or several extranodal structures such as the stomach, the lung, the eye and salivary glands. The lymphoma is generally of low grade and has indolent course. The aim of this article is to exemplify the most common radiological patterns of MALT lymphoma. (orig.)

    Mucosa associated lymphoid tissue (MALT) lymphomas are a group of non- Hodgkin"s lymphomas of low malignancy degree. The most frequent location is the gastrointestinal tract. Its primary pulmonary presentation is unusual and heterogeneous from point of view radiological. Woman 61 years old with antecedents of vitiligo, gastric ulcus, cirrhosis by VHC, that go into the hospital by sudden disnea, thoracic paint with pleural characterises and fever of 38.5 degrees C, Her thorax radiography and thoracic TAC showed nodes that affect to different pulmonary lobes. The cytology by PAAF confirms their malignant nature. In subsequent radiological controls it was notice the nodels took away completely and returns in different pulmonary place in each recurrence. The presentation like fluctuant pulmonary nodes is exceptional in a MALT lymphoma. It was described a higher incidence of VHC infection and tumour. The evidence of chronic hepatitis by virus C disease, and local chronic inflammatory process as well as autoimmune disorders may be considerate like a factor that contribute to MALT lymphoma.

    Full Text Available Breast involvement by lymphoma is uncommon and poses challenges in diagnosis. Breast involvement by malignant lymphoma, whether primary or secondary, is a rare event. Primary breast lymphomas account for 0.38% - 0.7% of all non-Hodgkin lymphomas, 1.7%-2.2% of all extranodal non-Hodgkin lymphomas, and only 0.04% - 0.5% of all breast cancer cases. Most frequent primary breast lymphomas are diffuse large B cell lymphomas (53%. Breast mucosa-associated lymphoid tissue (MALT lymphomas account for a small fraction of all the MALT lymphomas (1% - 2%. Herein we report a case of a patient with primary breast MALT lymphoma and its presentation on different imaging modalities. Two years after the presentation and treatment with eight cycles of chemotherapy, the patient is alive and well, without evidence of residual disease or recurrence.

    Full Text Available Cardiac involvement in malignant lymphoma is one of the least investigated subjects. Pericardial effusion is rarely symptomatic in patients of Hodgkin lymphoma (HL. Few case reports are available in the literature. There are case reports of diagnosed HL patients presenting with pericardial effusion. HL patients who present with recurrent episodes of pericardial effusion have also been reported. Pericardial effusion has also been reported in cases of non HL. However, pericardial effusion leading to cardiac tamponade as an initial presentation of HL is extremely rare. Very few such cases are there in the literature. Here, we present a case of a 26-year-old male patient who presented with cardiac tamponade and in due course was found to be a case of classical type of HL. This case is interesting because of its presentation.

    2018-05-01

    Full Text Available Background: Prurigo nodularis is a condition of unknown origin defined by papulonodular eruption and intense pruritus. Hodgkin lymphoma often presents nonspecific initial symptoms. An association between systemic malignancy and cutaneous manifestations has long been documented. We report a case of prurigo nodularis as a first presentation of Hodgkin lymphoma. Case: A 35-year-old woman presented with a 2-year history of pruritus. Previously diagnosed with bedbugs, the pruritus persisted even after insect eradication, with the appearance of papulonodular lesions consistent with chronic prurigo. The pruritus and the pain were refractory to all treatments. She had no past medical history or clinical, radiological, or laboratory findings. A lymphadenopathy was revealed 2 years after onset of the symptoms. Lymph node biopsy showed a nodular sclerosis Hodgkin lymphoma. The patient was initiated on chemotherapy and the skin lesions decreased. Conclusion: This case report of chronic prurigo as the first manifestation of a systemic malignancy reminds us of the importance of a systematic diagnostic approach to this kind of patients initially and throughout time, especially if the symptoms do not respond to treatment. Our case may question the role of imaging examinations in the management and follow-up of a persistent prurigo nodularis.

    Neurolymphomatosis refers to lymphoma that has infiltrated the peripheral nervous system and this is the least common clinical presentation of nervous system lymphoma. Most neurolymphomatosis is due to B-cell non-Hodgkin lymphoma, and most patients show lymphomatous infiltration in the meninges and brain parenchyma, in addition to peripheral nervous system involvement. We diagnosed a case of neurolymphomatosis that was confined to the right 4th and 5th lumbar nerve roots without involvement of the meninges or brain parenchyma in a patient with the nasal-type extranodal natural killer/T-cell lymphoma. We made this diagnosis based on the MRI and 18F-FDG PET-CT findings and the clinical manifestations

It is characterized by a relative indolent course, splenomegaly, moderate lymphocytosis, and an intrasinusoidal pattern of involvement, especially in the bone marrow. It is postulated that the neoplastic clone originates from persistent antigenic stimulation of marginal zone B-cells. Molecular and cytogenetic studies have failed to show specific alterations. There is no standard criterion to initiate treatment, which may include a watch and wait policy, splenectomy, or chemo/immunotherapy. This review highlights the main features of this entity, reassessing the guidelines for diagnosis, prognostic factors, staging, and management published by the SMZL Working Group (2008.

    Full Text Available Acute renal failure (ARF in patients with malignancy occurs due to causes such as prerenal, renal and post renal as in normal population. Tumor infiltration of kidneys is usually uncommon. However, renal function may be impaired in fast-growing hematological malignancies such as acute leukemia or lymphoma, depending on tumor involvement. Herein, we presented a case of ARF and later diagnosed as B-cell Non-Hodgkin's lymphoma. 54-year-old male patient was admitted due to ARF. Although development of ARF due to tumor infiltration is rare, in cases who did not have risk factors for development of ARF, leukemic or lymphomatous infiltration should be considered.

    Hashimoto's thyroiditis was recently divided into IgG4-plasma cell-rich and IgG4-plasma cell-poor subtypes. The former, also known as IgG4 thyroiditis, is associated with clinical, serological, sonographic and morphological features that are distinctive from those of the non-IgG4 subgroup. We describe an interesting case of IgG4-positive mucosa-associated lymphoid tissue (MALT) lymphoma arising in a background of IgG4 thyroiditis. The thyroid gland showed typical features of IgG4 thyroiditis, including characteristic patterns of fibrosis. A dense lymphoplasmacytic infiltrate diffusely involved the entire gland without formation of a destructive tumour mass. Lymphoepithelial lesions were prominent. There were abundant IgG4-positive plasma cells, with the IgG4/IgG ratio exceeding 40%. The IgG4-positive plasma cells were monotypic for kappa light chain, and there was monoclonal IGH rearrangement. Fluorescence in-situ hybridization revealed IGH translocation without translocation of MALT1, bcl-10, or FOXP1. This represents the first case of IgG4-producing MALT lymphoma associated with IgG4 thyroiditis. IGH translocation with an unknown partner gene was identified. We suggest the performance of serum and immunohistochemical investigations for IgG and IgG4 in all cases of Hashimoto's thyroiditis to diagnose IgG4 thyroiditis. In addition, clonality assays and light chain studies are useful to exclude a low-grade lymphoma arising in this context. © 2015 John Wiley & Sons Ltd.

    2012-01-01

    Full Text Available The gastrointestinal tract (GIT is the most commonly involved site of extranodal lymphomas. The close association between chronic inflammation and specific GIT lymphomas not only provide interesting insights into the pathobiology of lymphomas but also poses unique diagnostic challenges. A clear understanding of marginal zone and mucosa associated lymphoid tissue (MALT in health and disease is helpful to place GIT lymphomas in proper context. A wide variety of lymphomas besides MALT lymphomas occur in various parts of the GIT. The characteristic pathological, immunophenotypic, and genetic features of different GIT lymphomas categorized according to World Health Organization (WHO classification are presented. The epidemiological, clinical, and pathological features of lymphomas occurring in each part of the GIT are summarized and the key points regarding lymphomas at each site are emphasized. A tabular summary of the important differential diagnostic considerations at each site is given and suggestions for a minimal diagnostic work up are provided.

    Non-Hodgkin's lymphomas are a heterogeneous group of malignancies of the lymphoid system. The exact etiology for most lymphomas has not been determined, but both viral and bacterial infections have been shown to be important etiologic factors. The WHO classification of hematopoietic and lymphoid tumours classifies lymphomas into B-cell and T-cell neoplasms. B-cell lymphomas account for more than 85% of all lymphomas. The Ann Arbor staging classification has been adopted by the AJCC and UICC as a standard for classifying extent of anatomic disease. The two most common histologic disease entities are follicular lymphomas and diffuse large B-cell lymphomas. The management of follicular lymphomas is used as a paradigm for the management of all indolent lymphomas. Radiation therapy is used for stage I and II disease, while alkylating agent chemotherapy, immunotherapy and radioimmunotherapy are most frequently used in stage III and IV disease that requires treatment. Most patients with follicular lymphoma enjoy prolonged survival, but at present there is no evidence that those with stage III and IV follicular lymphoma can be cured. Diffuse large B-cell lymphomas serve as a paradigm for treating aggressive lymphomas. Stage I and II diffuse large cell lymphomas are generally treated with combined modality therapy with doxorubicin-based chemotherapy followed by involved field radiation therapy, while those with stage III and IV disease are treated with chemotherapy alone. Patients who fail initial management are treated with further chemotherapy. High-dose chemotherapy with stem cell rescue has been shown to be particularly effective as salvage treatment for diffuse large cell lymphomas. The management of a heterogeneous group of primary extranodal lymphomas in general follows the above treatment principles, with additional treatment being required for those with a high risk of CNS failures, or involvement of contralateral paired organs.

    Full Text Available We describe the case of a 44-year-old woman with primary Burkitt lymphoma of the heart who presented with abdominal bloating and epigastric discomfort secondary to tamponade physiology caused by a large pericardial effusion. The pericardial fluid contained a large number of highly atypical lymphocytes with moderate basophilic cytoplasm, rare punched-out vacuoles, a vesicular nuclear chromatin, large nucleolus, and marginated chromatin that by FISH were positive for the 8;14 translocation. She had no other sites of disease. She was treated with four alternating cycles of modified CODOX-M and IVAC in combination with rituximab and remains in remission more than 5 years since diagnosis.

    Here, we give an updated overview of the subtype distribution of lymphomas in East Asia and also present the genome sequencing data on two major subtypes of these tumors. The distribution of lymphoma types/subtypes among East Asian countries is very similar, with a lower proportion of B-cell malignancies and a higher proportion of T/natural killer (NK)-cell lymphomas as compared to Western populations. Extranodal NK/T-cell lymphoma is more frequently observed in East Asia, whereas follicular lymphoma and chronic lymphocytic leukemia, are proportionally lower. The incidence rate of lymphoma subtypes in Asians living in the US was generally intermediate to the general rate in US and Asia, suggesting that both genetic and environmental factors may underlie the geographical variations observed.Key cancer driver mutations have been identified in Asian patients with diffuse large B-cell lymphoma or extranodal NK/T-cell lymphoma through genome sequencing. A distinct somatic mutation profile has also been observed in Chinese diffuse large B-cell lymphoma patients. The incidence and distribution of lymphoma subtypes differed significantly between patients from East Asia and Western countries, suggesting subtype-specific etiologic mechanisms. Further studies on the mechanism underlying these geographical variations may give new insights into our understanding of lymphomagenesis.

    duration of chemotherapy is related to the bulk of tumour at presentation and anatomic extent of the disease. The recently completed ECOG randomized trial of chemotherapy and radiation versus chemotherapy alone confirmed benefit of RT in the localized lymphomas. Non-Hodgkin's lymphoma may involve any part of the body. Presentation in extranodal sites is common. Primary extranodal lymphomas are often localized, highly curable with RT or combined modality therapy. These diseases are of particular importance to radiation oncologists as they require a special attention to patterns of spread and treatment planning. However, the principles of management of extranodal lymphoma follow those applicable to nodal presentations

    We report a case of a 53-year-old man presenting with shoulder pain mimicking septic arthritis. Laboratory findings were atypical. Biopsy performed to assess for possible osteomyelitis demonstrated chronic lymphocytic leukemia/small lymphocytic lymphoma. Intra-articular lymphoma is a rare but important consideration in patients with atypical clinical presentation. Imaging alone may be insufficient to render diagnosis as lymphoma can mimic infection, synovial hypertrophic processes, and depositional arthropathy. (orig.)

Our patient presented with a large pleural effusion and right sided pleural studding, initially attributed to a new diagnosis of mantle cell lymphoma. Rare atypical epithelial cells were also seen amongst the clonal population of lymphocytes. The patient lacked systemic manifestations of mantle cell lymphoma and did not improve with chemotherapy. A pleural biopsy ultimately revealed the presence of an undifferentiated carcinoma, favoring a lung primary. A discussion of synchronous pleural space malignancies involving lymphomas is given.

    Thyroid lymphoma is a rare disease entity of elderly females. Chronic lymphocytic thyroiditis is said to be the precursor of thyroid lymphoma, suggesting a role of chronic antigen stimulation in the development of the disease. We present a case of male with lymphocytic thyroiditis who presented with painless progressive neck enlargement and pathology revealed features of high grade lymphoma. Staging and posttreatment 18 F-fluorodeoxyglucose ( 18 F-FDG) positron emission tomography/computed tomography (PET/CT) was performed. This report reemphasizes the role of 18 F-FDG PET/CT in the diagnosis, staging, and assessment of therapy response in patients with extranodal lymphoma, including the primary thyroid lymphoma

    Full Text Available In the oral cavity, extranodal non-Hodgkin's lymphoma can occur in the periapical region either in the maxilla or mandible. Also, it can mimic inflammatory lesions that arise around the teeth apices such as periapical granuloma, radicular cyst and osteomyelitis. Misdiagnosis of lymphomas in the jaws may reduce the chance of successful treatment and worsen the prognosis. Therefore, any growth of periapical tissue must be submitted for histopathological evaluation to avoid a delay in the diagnosis. We present a case of extranodal non-Hodgkin's lymphoma of a 53-year-old male in the right posterior mandible that was initially misdiagnosed as a reactive periapical lesion. This case illustrates the importance for both the pathologist and the clinician of considering malignant lesions such as lymphoma in the differential diagnosis of periapical radiolucency.

    A 67-year-old woman with non-insulin dependent diabetes mellitus with a history consistent with a right axillary abscess, presented to her general practitioner (GP). A diagnosis of folliculitis was made and the GP started a course of flucloxacillin. Despite antibiotics, the patient's symptoms worsened and the abscess increased in size. This prompted her GP to perform an incision and drainage procedure of the abscess. The practice nurse subsequently oversaw the follow-up care of the wound. Two months after the incision and drainage, and after regular wound dressing, the patient was referred to the acute surgical team with a complicated, non-healing right axillary abscess cavity and associated generalised right breast cellulitis. There was no history of breast symptoms prior to the onset of the axillary abscess. The patient underwent wound debridement, washout and application of negative pressure vacuum therapy. Biopsies revealed primary breast lymphoma (B-cell). She underwent radical chemotherapy and is currently in remission. 2015 BMJ Publishing Group Ltd.

    Extranodal marginal zone B-cell lymphomas of the mucosa-associated lymphoid tissue (MALT) arise from lymphoid populations that are induced by chronic inflammation in extranodal sites. The most frequently affected organ is the stomach, where MALT lymphoma is incontrovertibly associated with a chronic gastritis induced by a microbial pathogen, Helicobacter pylori. Gastric MALT lymphoma therefore represents a paradigm for evaluating inflammation-associated lymphomagenesis, which may lead to a deeper understanding of a possible etiologic association between other microorganisms and nongastric marginal zone lymphomas. Besides infectious etiology, chronic inflammation caused by autoimmune diseases, such as Sjögren syndrome or Hashimoto thyroiditis, can also carry a significant risk factor for the development of marginal zone lymphoma. In addition to the continuous antigenic drive, additional oncogenic events play a relevant role in lymphoma growth and progression to the point at which the lymphoproliferative process may eventually become independent of antigenic stimulation. Recent studies on MALT lymphomas have in fact demonstrated genetic alterations affecting the NF-κB) pathway, a major signaling pathway involved in many cancers. This review aims to present marginal zone lymphoma as an example of the close pathogenetic link between chronic inflammation and tumor development, with particular attention to the role of infectious agents and the integration of these observations into everyday clinical practice.

    Full Text Available Discordant lymphoma is rare condition in which different types of malignant lymphomas occurring in different anatomic sites. The two diseases may present clinically as concurrent or sequential disease (10. Herein we are reporting a Pakistani female in her 60s, a carrier of hepatitis B virus with multiple comorbidities presented with cervical lymphadenopathy, diagnosed as Hodgkin's lymphoma, mixed cellularity. During the staging workup, the patient was discovered to have extensive bone marrow (BM involvement by Burkitt leukaemia/lymphoma (BL. Cytogenetic analysis revealed positivity for t(8;14(q24;q32 confirmed by Fluorescence In Situ Hybridization (FISH for IGH/MYC. Epstein-Barr virus (EBV was demonstrated heavily in our case, with (EBV DNA of 24,295,560 copies/ml by PCR at time of presentation, in addition, the neoplastic cells in both diagnostic tissues (cervical lymph node and BM demonstrated positivity for EBV. A diagnosis of concomitant EBV related discordant lymphoma (classical Hodgkin lymphoma (cHL and Burkitt lymphoma (BL in leukemic phase was made. Among all reported cases, this case is highly exceptional because it is the first case of discordant/composite lymphoma, with this combination and concomitant presentation. Since we are dealing with a case with an exceptionally rare combination, we found it significant to elaborate more on its clinical features, contributing factors including EBV role, response to treatment, complications, and prognosis.

  15. Non-Hodgkin's lymphoma presenting as a primary bladder tumor: a case report

    2010-04-01

    Full Text Available Abstract Introduction Primary lymphoma of the bladder represents 0.2% of all bladder malignancies. Secondary involvement of the bladder by malignant lymphoma occurs in 10% to 50% of cases. Most lymphomas of the bladder are non-Hodgkin's lymphomas of the B-cell type, with preponderance among women. The impact of positron emission tomography (PET on tumor staging has recently become very important due to its use in the study of diagnosis extension and individual therapy design. Case presentation We report the case of a 79-year-old Caucasian man with intermittent haematuria as the presenting symptom of non-Hodgkin's lymphoma of the bladder. He was first diagnosed with primary lymphoma of the bladder using the current staging method, but a positron emission tomography study subsequently revealed that he instead had a secondary involvement of the bladder. Conclusion The staging of non-Hodgkin's lymphomas, which is useful in order to plan accurate therapy, has been changing since the introduction of positron emission tomography scanning. Primary lymphomas of the bladder, although very rare, may be even more uncommon when this imaging technique is used to assess the extension of the disease. Although the interpretation of this technique has some limitations that should be taken into account, the extensive use of positron emission tomography should nonetheless help improve the diagnosis of this disease.

    2012-01-01

    Full Text Available Paravertebral malignant tumors constitute 4.8% of cancer cases in pediatric oncology and are mostly composed of neuroblastoma (46.4% and soft tissue sarcomas (35.7%. We describe the case of a Caucasian 6-year-old boy who was admitted for middle back pain radiated to limbs and progressively increasing weakness of the legs, suggesting a spinal cord disease. The exploration revealed two paravertebral masses extending through the neural foraminae into the epidural space. The association with elevated serum neuron specific enolase suggested at first the diagnosis of neuroblastoma, but the pathological examination revealed a Burkitt's lymphoma. This is a rare location of sporadic Burkitt's lymphoma with neurologic syndrome as first symptoms.

  17. Lymphomas or leukemia presenting as ovarian tumors. An analysis of 42 cases.

    Osborne, B M; Robboy, S J

    1983-11-15

    Forty cases of ovarian lymphoma and two of extramedullary leukemia were examined with emphasis on histologic types correlated with age, modes of presentation, operative findings, including frequency of bilaterality and omental spread, clinical course following therapy, and problems in differential diagnosis. Although most cases were referred with diagnoses other than lymphoma (granulosa cell tumor or dysgerminoma, occasionally anaplastic tumor, Krukenberg tumor, or metastatic breast carcinoma), utilization of sections cut at 4 mu and stained with hematoxylin and eosin, or sections stained by the methyl green pyronine (MGP), naphthol-ASD esterase (NASD) or periodic acid-Schiff (PAS) methods helped bring out the lymphoid or hematopoietic nature of the cells. Sixteen patients were under 20 years of age. They had small noncleaved cell lymphoma (undifferentiated Burkitt's and non-Burkitt's, 10 cases), diffuse immunoblastic large cell lymphoma (4 cases), or acute granulocytic leukemia (2 cases). Twenty-six patients were 29 to 74 years of age and had diffuse large cell lymphoma (10 cases), diffuse immunoblastic large cell lymphoma (9 cases), follicular (nodular) lymphoma (6 cases) or small noncleaved cell lymphoma (1 case). Pain with an abdominal or pelvic mass was the most common presentation. Nine tumors were discovered during investigation of other gynecologic complaints. At laparotomy, the tumors in 55% of cases involved both ovaries, and in 64% also involved extragonadal sites (usually omentum, fallopian tubes, or lymph nodes). Seventeen patients had tumor affecting one ovary, seven of these without any evidence of extragonadal spread. Forty-two percent (15) of 37 patients with follow-up were alive after 2 years. Only nine patients survived more than 5 years; two subsequently died of lymphoma. Favorable prognostic features included: (1) FIGO stage IA; (2) unilateral ovarian involvement; (3) focal involvement of one ovary; and (4) follicular (nodular) lymphoma.

    2014-01-01

    Today approximately 70% of patients with Hodgkin lymphoma can be cured with the combined-modality therapy. Tumor burden, the importance of which was demonstrated 15 years ago for the first time, is a powerful prognostic factor. Data of literature of representations on predictive value of Hodgkin's lymphoma tumor burden are shown in the article. The difficult immunological relations between tumor cells and reactive ones lead to development of the main symptoms. Nevertheless, the collective sign of tumor burden shows the greatest influence on survival and on probability of resistance, which relative risk can be predicted on this variable and treatment program. Patients with bulky disease need escalated therapy with high-dose chemotherapy. Integration into predictive models of the variable will change an expected contribution of clinical and laboratory parameters in the regression analyses constructed on patients with Hodgkin's lymphoma. Today the role of diagnostic functional methods, in particular a positron emission tomography, for metabolic active measurement is conducted which allows excluding a reactive component.

    In pediatric patients renal lymphoma frequently presents in the form of multiple, bilateral mass lesions, infrequently as a single or retroperitoneal mass, and rarely as diffuse infiltrative lesions. In patients with apparent central nervous system involvement close attention to other physical and laboratory findings are essential for preventing a delay in the final diagnosis. Herein we present a pediatric patient with renal lymphoma that presented with central nervous system findings that caused a delay in diagnosis. None declared.

    2012-04-01

    Lymphoblastic lymphoma is the second most common type of non-Hodgkin lymphoma seen in children. Approximately, 90% of lymphoblastic lymphomas arise from T cells, with the remaining 10% being B-cell-lineage derived. Although T-cell lymphoblastic lymphoma most frequently occurs in the anterior mediastinum (thymus), B-cell lymphoblastic lymphoma (B-LBL) predominates in extranodal sites such as skin and bone. Here, we describe a pediatric B-LBL patient who presented with extensive abdominal involvement and whose lymphoma cells displayed segmental duplication of the mixed lineage leukemia (MLL) gene. MLL duplication/amplification has been described primarily in acute myeloid leukemia and myelodysplastic syndrome with no published reports of discrete MLL duplication/amplification events in B-LBL. The MLL gene duplication noted in this case may represent a novel mechanism for tumorigenesis in B-LBL.

    Multiple lymphomatous polyposis (HLP) is an unusual form of non-Hodgkin's lymphoma characterized by polyps throughout the gastrointestinal tract. It has been reported that most MLP are observed in cases with mantle cell lymphoma of B-cell type. We herein present a case of a 66-year-old man with adult T-cell leukemia/lymphoma (ATLL). Colonoscopy revealed MLP throughout the colon and histopathological findings of ATLL cell infiltration. The patient died despite combination of chemotherapy. The literature of manifestations of colonic involvement of ATLL is reviewed and the importance of endoscopic evaluation to differentiate ATLL intestinal lesions from opportunistic infectious enterocolitis is discussed.

    Rosai Dorfman disease involves an abnormal proliferation of histiocytes. This abnormal growth tends to occur within the lymph nodes, with occasional extranodal presentation. Rosai Dorfman disease is a rare disease, and the extranodal cases are even more uncommon. We report a rare case of extranodal Rosai Dorfman disease in multiple sites in a 56 year old male patient. Abdominopelvic CT revealed soft tissue attenuation masses, encasing both the renal pelvis and both ureters, as well as the thoracic vertebra. Following the neck sonography, both submandibular glands had an enlarged honey combed appearance. Although Rosai Dorfman disease is rare, it should be considered as a potential differential diagnosis when multiple sites involving soft tissue attenuation masses are observed with sonogram and CT.

    Full Text Available Malignant lymphoma may occur in the oral cavity and oropharynx, but is most commonly located in Waldeyer's ring, particularly in the palatine and lingual tonsil. The occurrence of malignant lymphoma in the tongue is very rare. Clinical features are nonspecific ulcerative lesions that do not heal. In the literature, the majority of casesare non-Hodgkin’s lymphoma, diffuse large B cell type; however T-cell phenotype also may occur. We describe a 60-year-old man who presented with an ulcerative mass in the left lateral aspect of his tongue, unresponsive to medical therapy. After tissue biopsy, histopathological and immunohistochemical analyses confirmed a diagnosis of non-Hodgkin’s lymphoma, diffuse large B cell type.

    Full Text Available Abstract Background Primary non-Hodgkin lymphoma (NHL of the breast represents 0.04–0.5% of malignant lesions of the breast and accounts for 1.7–2.2% of extra-nodal NHL. Most primary cases are of B-cell phenotype and only rare cases are of T-cell phenotype. Anaplastic large cell lymphoma (ALCL is a rare T-cell lymphoma typically seen in children and young adults with the breast being one of the least common locations. There are a total of eleven cases of primary ALCL of the breast described in the literature. Eight of these cases occurred in proximity to breast implants, four in relation to silicone breast implant and three in relation to saline filled breast implant with three out of the eight implant related cases having previous history of breast cancer treated surgically. Adjuvant postoperative chemotherapy is given in only one case. Secondary hematological malignancies after breast cancer chemotherapy have been reported in literature. However in contrast to acute myeloid leukemia (AML, the association between lymphoma and administration of chemotherapy has never been clearly demonstrated. Case Presentation In this report we present a case of primary ALCL of the breast arising in reconstruction mamoplasty capsule of saline filled breast implant after radical mastectomy for infiltrating ductal carcinoma followed by postoperative chemotherapy twelve years ago. Conclusion Primary ALK negative ALCL arising at the site of saline filled breast implant is rare. It is still unclear whether chemotherapy and breast implantation increases risk of secondary hematological malignancies significantly. However, it is important to be aware of these complications and need for careful pathologic examination of tissue removed for implant related complications to make the correct diagnosis for further patient management and treatment. It is important to be aware of this entity at this site as it can be easily misdiagnosed on histologic grounds and to exclude

    Full Text Available The management of classical Hodgkin's lymphoma (CHL is a success story of modern multi-agent haemato-oncology. Prior to the middle of the twentieth century CHL was fatal in the majority of cases. Introduction of single agent radiotherapy (RT demonstrated for the first time that these patients could be cured. Developments in chemotherapy including the mechlorethamine, vincristine, procarbazine and prednisolone (MOPP and Adriamycin, bleomycin, vinblastine and dacarbazine (ABVD regimens have resulted in cure rates of over 80%. Even in relapse, CHL patients can be salvaged with high dose chemotherapy and autologous haematopoietic stem cell transplantation (ASCT. Challenges remain, however, in finding new strategies to manage the small number of patients who continue to relapse or progress. In addition, the young age of many Hodgkin's patients forces difficult decisions in balancing the benefit of early disease control against the survival disadvantage of late toxicity. In this article we aim to summarise past trials, define the current standard of care and appraise future developments in the management of CHL.

    2014-10-01

    Full Text Available Background: Primary cutaneous B-cell lymphoma typically localizes to the skin, and dissemination to internal organs is rare. Lymphomatous involvement of the breasts is also rare. We describe the clinical and radiological findings of an unusual case of primary cutaneous B-cell lymphoma presenting as an isolated breast mass without associated skin changes. Case Presentation: The patient was a 55-year-old Caucasian female who initially presented with cutaneous B-cell lymphoma around her eyes and forehead with recurrence involving the skin between her breasts. Three years after terminating treatment due to a lack of symptoms, she presented for an annual screening mammogram that found a new mass in her upper inner right breast without imaging signs of cutaneous extension. On physical examination, there were no corresponding skin findings. Due to the suspicious imaging features of the mass that caused concern for primary breast malignancy, she underwent a core biopsy which revealed cutaneous B-cell lymphoma. Conclusion: When evaluating patients with a systemic disease who present with findings atypical for that process, it is important to still consider the systemic disease as a potential etiology, particularly with lymphoma given its reputation as a great mimicker.

    During the period 1984-1989 the authors have observed 20 patients with non-immuno-proliferative small intestinal disease (non-IPSID) small intestinal lymphomas, 11 males and 9 females. In 11 patients the first symptoms were abdominal cramps requiring laparotomy, in 4 ills, and in 5 perforation with peritonitis. Resection of the involved part of the intestine was performed in 17 patients. Lymphoma tissue was present in 4 of 5 retrogradely examined resection lines on macroscopically normal small intestine. According to Working Formulation, 3 patients had low grade, 3 intermediate grade and 14 high grade histology. Affection of extra intestinal/mesenteric structures was found in 18 of 20 patients, with a total of other lymphoma localizations. 8 of 20 affection of the nasopharynx and/or Waldeyer's ring. According to Crowther's classification 55 % patients were in Stage IV, 35 % in Stage III and 10 % in stage Ib. All patients were treated with chemotherapy, 13 with ProMACE regimen and 7 with CHOP-type regimens. Ten of twenty patients are alive and in complete remission for over 5 years (7 of 11 of Stage IV and 3 of 9 of Stage Ib/III; 8 of 14 with high grade and 2 of 6 with intermediate/low grade histology). Our results point to the fact that in non-IPSID lymphoma of the small intestine, lymphoma involvement of the intestinal wall might be present beyond obvious lymphoma lesions. Most patients with apparently primary small intestinal lymphoma have a widespread disease. Thus, local forms of treatment such as surgery and/or radiotherapy can not be expected to be curative in the majority of patients. Data from this study suggest that following initial surgery the chemotherapy is the treatment of choice for these patients. (author)

    Full Text Available Intussusception is a common cause of abdominal pain in children. Although most cases are idiopathic, about 10% of cases have a pathologic lead point. Burkitt's lymphoma is not a common etiology. Burkitt's lymphoma might present primarily as intussusception in children but has rarely been associated with appendicitis. We report a case in which a 10-year-old obese boy who initially presented with acute appendicitis due to ileocolic intussusception with appendiceal invagination. He underwent one-trocar laparoscopy and antibiotic treatment. The symptoms recurred 10 days after discharge. Colonoscopy disclosed ileocecal Burkitt's lymphoma as the pathological lead point. This case emphasizes the importance of the age of the patient and the anatomic location of the intussusception related to possible etiology, and hence the most appropriate surgical procedure.

    Marcelo Corti

    Full Text Available Intestinal intussusception rarely occurs in the adult population and accounts only for 1% to 5% of all the causes of intestinal obstruction. This complication is more frequent in the small bowel and can be due to different aetiologies, including inflammatory, infectious or neoplastic diseases. Malignancies account for 50% to 60% of all cases of colon invagination. The gastrointestinal (GI tract is the most common site for extra-nodal non-Hodgkin lymphomas (NHL, representing 5% to 20% of all the cases. However, primary NHL of the GI tract is a very infrequent clinic-pathological entity and accounts only for 1% to 4% of all the neoplasms of the GI tract. Primary NHL of the colon is a rare disease and it comprises only 0.2% to 1.2% of all colonic malignancies. Here we describe a case of an AIDS adult patient who developed an intussusception secondary to a primary large B cell lymphoma of the transverse colon. English and Spanish literature was reviewed.

    2018-04-01

    There are exceedingly rare reports of patients with epidermotropic B-cell lymphomas. A subset presented with intermittent, variably pruritic papular eruptions and involvement of their spleens, peripheral blood and bone marrow at the time of diagnosis. Furthermore, some experienced an indolent course despite dissemination of their lymphomas. We report a 66-year-old woman with a 12-year history of intermittent eruptions of non-pruritic, salmon-colored papules on her torso and proximal extremities that occurred in winter and resolved with outdoor activity in spring. Skin biopsy revealed an epidermotropic B-cell lymphoma with a non-specific B-cell phenotype and heavy chain class switching with IgG expression. On workup, our patient exhibited mild splenomegaly and low-level involvement of her peripheral blood and bone marrow by a kappa-restricted B-cell population. A splenic B-cell lymphoma was diagnosed. Considering her longstanding history and absences of cytopenias, our patient has been followed without splenectomy or systemic therapy. Furthermore, the papules have responded dramatically to narrowband UVB. Our case and a review of similar rare reports aim to raise awareness among dermatopathologists and dermatologists of a clinically distinct and indolent subset of epidermotropic splenic lymphomas with characteristic clinical and histologic findings. © 2018 John Wiley & Sons A/S.

    2014-01-01

    Full Text Available Non-Hodgkin’s lymphoma of the cervix is an extremely uncommon entity, with no standard established treatment protocol. A 43-year-old asymptomatic female with a history of dual hit blastic B-cell lymphoma/leukemia in complete remission presented with an incidental cervical mass, which was initially felt to represent a cervical fibroid on computed tomography (CT. It was further evaluated with ultrasound, biopsy, and positron emission tomography-computed tomography (PET-CT, which demonstrated a growing biopsy-proven lymphomatous mass and new humeral head lesion. The patient was started on chemotherapy to control the newly diagnosed humeral head lesion, which then regressed. She then underwent radiation to the cervix with significant improvement in the cervical lymphoma. A review of cross-sectional imaging findings of lymphoma of the cervix is provided, including how to differentiate it from other more common diseases of the cervix. Clinical awareness of rare cervical masses such as lymphoma is very important in order to achieve timely diagnosis and appropriate treatment.

  9. Rare transformation to double hit lymphoma in Waldenstrom's macroglobulinemia.

    Okolo, Onyemaechi N; Johnson, Ariel C; Yun, Seongseok; Arnold, Stacy J; Anwer, Faiz

    2017-08-01

    Waldenström macroglobulinemia (WM) is a lymphoproliferative lymphoma that is characterized by monoclonal immunoglobulin M (IgM) protein and bone marrow infiltration. Its incidence is rare and rarer still is its ability to transform to a B-cell lymphoma, particularly the aggressive diffuse large B-cell lymphoma, which bodes a poor prognosis. When transformation includes mutations of MYC, BCL-2 and/or BCL-6, it is known as a 'double hit' or 'triple hit' lymphoma respectively. This paper presents a rare case of WM with mutations positive for MYC and BCL2, making it a case of double hit B-cell lymphoplasmacytic lymphoma with plasmatic differentiation without morphological transformation to aggressive histology like DLBCL. The paper also broadens to include discussions on current topics in the classification, diagnosis, possible causes of transformation, and treatment of WM, including transformation to double hit lymphoma. The significance of this case lies in that the presence of double hit lymphoma-like genetic mutations in WM have not been previously described in the literature and potentially such changes are harbinger of extra-nodal presentation, aggressive growth, and possibly poor prognosis, if data from other double-hit lymphoma are extrapolated.

    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

  12. Primary hepatic lymphoma presenting as fulminant hepatic failure with hyperferritinemia: A case report

    Directory of Open Access Journals (Sweden)

    Haider Fyeza S

    2008-08-01

    Full Text Available Abstract Introduction Primary hepatic lymphoma is an unusual form of non-Hodgkin's lymphoma that usually presents with constitutional symptoms, hepatomegaly and signs of cholestatic jaundice. Diffuse hepatic infiltration is uncommon and presentation with acute hepatic failure even more rare. The presence of markedly elevated ferritin levels can complicate the evaluation process and suggest alternative diagnoses. We present the case of a middle-aged woman exhibiting pancytopenia, hyperferritinemia and rapidly deteriorating to develop acute hepatic failure. Her initial clinical picture led to a working diagnosis of adult onset Still's disease with probable hemophagocytic syndrome before her worsening liver function necessitated a percutaneous liver biopsy and establishment of the final diagnosis of primary hepatic lymphoma. Conclusion Primary hepatic lymphoma is an uncommon malignancy and its manifestation as progressive hepatitis or acute fulminant hepatic failure can be difficult to diagnose. The presence of constitutional symptoms, pancytopenia and high ferritin levels can complicate the evaluation process. A liver biopsy early in the course of liver dysfunction may establish the diagnosis without a higher risk of bleeding complications seen once liver failure sets in.

    Lymphomas arising in the adrenal are rare, and to our knowledge, 2 cases of Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphomas (DLBCL) in an adrenal pseudocyst have been reported. We report an incidental EBV-positive DLBCL arising in an adrenal pseudocyst in a 58-year-old man with a 7-year history of lymphoplasmacytic lymphoma (LPL). The DLBCL was present in the fibrinous exudate, while the LPL resided in the cyst wall. The patient underwent de-roofing of the same cyst 3 years previously; review of histology revealed foci of LPL in the cyst wall, but not of DLBCL. There have been reports of similar microscopic EBV-positive DLBCLs within enclosed cystic spaces. However, all these cases were incidental extranodal primary DLBCLs. Since residual LPL was present alongside DLBCL, with similar light chain restriction, we propose that this may represent transformation, rather than a de novo primary EBV-driven lymphoma.

    Nodal marginal zone lymphoma (NMZL) is a rare type of B-cell non-Hodgkin lymphoma. This study assessed the clinical features of 56 patients with NMZL in comparison to 46 patients with follicular lymphoma (FL). Patients with NMZL and FL had a largely similar clinical presentation, but patients with FL had a higher disease stage at presentation, more frequent abdominal lymphadenopathy and bone marrow involvement, and showed more common transformation into diffuse large B-cell lymphoma (DLBCL) during the course of disease. Overall survival and event-free survival were similar for patients with NMZL and FL, but factors associated with worse prognosis differed between the two groups. Transformation into DLBCL was associated with a significantly poorer outcome in both groups, but the phenotypes were different: DLBCL arising in FL was mainly of germinal center B-cell phenotype, whereas DLBCL arising in NMZL was mainly of non-germinal center B-cell phenotype.

    2014-01-01

    We present a 71-year-old female with human herpes virus 8 (HHV8)-unrelated primary effusion lymphoma (PEL)-like lymphoma. Dyspnea and pericardial effusion led to pericardiocentesis, diagnosing diffuse large B-cell lymphoma. She underwent positron emission tomography/computed tomography (PET/CT), which demonstrated hypermetabolic pericardial, pleural, and ascites fluid without lymphadenopathy elsewhere. Malignant fluid in the absence of lymphadenopathy is a hallmark of PEL. PEL is associated with immunodeficiency states such as acquired immunodeficiency syndrome (AIDS) and infectious agents such as HHV8. Our patient had no such history and had not received immunosuppressive chemotherapy. We present the PET/CT findings of this rare case of HHV8-unrelated PEL-like lymphoma

    Full Text Available Primary lymphoma of the temporal bone is an unusual finding in clinical practice and bilateral affection is even more rare. To the best of our knowledge, there are no reports of bilateral primary temporal bone lymphoma without middle ear involvement in the English medical literature so far. We report, for the first time, a case of primary lymphoma involving both temporal bones which presented with left-sided infranuclear facial palsy. A combination of contrast enhanced magnetic resonance imaging (MRI and high resolution computed tomography (HRCT was used to characterize and to map the extent of the lesion, as well as to identify the exact site of facial nerve affection. An excision biopsy and immunohistochemistry revealed diffuse large B-cell non-Hodgkin’s lymphoma (DLBCL. Whole body fluorodeoxyglucose (FDG positron emission tomography-computed tomography study (PET-CT was performed to stage the disease. The patient was treated with chemotherapy and radiation therapy and is now on regular follow-up. The patient is alive and asymptomatic without disease progression for the last twenty months after initial diagnosis.

    Somatostatin receptor (SSTR) scintigraphy and gallium-67 citrate ( 67 Ga) scintigraphy have been used for visualisation of Hodgkin's lymphoma and non-Hodgkin's lymphoma. However, experience with B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT) type is very limited. The aim of this study was to prospectively compare the 67 Ga scintigraphy results with those obtained by 111 In-DOTA-dPhe 1 -Tyr 3 -octreotide ( 111 In-DOTA-TOCT) and 111 In-DOTA-lanreotide ( 111 In-DOTA-LAN) scintigraphy in patients with proven MALT-type lymphoma. Comparative scintigraphic examinations using 67 Ga, 111 In-DOTA-TOCT and 111 In-DOTA-LAN were performed in 18 patients (11 female and 7 male, median age 64±15 years) with histologically verified MALT-type lymphomas of various origin. Planar and single-photon emission tomography imaging acquisitions were performed after injection of a mean dose of 185±26 MBq 67 Ga and 165±20 MBq 111 In-DOTA-TOCT or 111 In-DOTA-LAN. All scintigraphic results were correlated with other conventional examinations including gastroscopy, colonoscopy, endosonoscopy, ophthalmologic investigation, CT of the thorax and abdomen and bone marrow biopsy. This comparative study showed that 67 Ga scintigraphy found abnormalities in 10 of 16 patients (63%) and detected 18 of 31 clinically involved sites (58%), but was false positive in three patients. 111 In-DOTA-TOCT found abnormalities in 9 of 15 patients (60%) and detected 15 of 27 clinical lesions (56%); it was false positive in two patients. 111 In-DOTA-LAN scintigraphy showed abnormalities in 7 of 11 patients (64%) and found 12 of 22 clinical lesions (55%). False-positive 111 In-DOTA-LAN scan results were found in two patients. For supra-diaphragmatic lesions, 67 Ga scintigraphy detected 12 of 16 sites (75%). 111 In-DOTA-TOCT scintigraphy revealed 7 of 15 lesions (47%). 111 In-DOTA-LAN showed 6 of 12 positive sites (50%). For infra-diaphragmatic involvement, the sensitivities of 67 Ga, 111 In

    Full Text Available Mucosa associated lymphoid tissue (MALT lymphomas are rare neoplasms. They are most common in the stomach followed by small intestine and colon. The symptoms are nonspecific and generally do not present with intussusception. Here we report a rare clinical entity in which a 35-year-old female presented to the emergency with severe abdominal pain which was sudden in onset. History revealed that she had been having vague mild abdominal pain for 2 years. Ultrasonography showed ileocolic intussusception with hypoechoic lesion of 54 × 46 mm seen at the lead point. Emergency laparotomy with the right hemi-colectomy was done. The specimen was sent for histopathological examination which revealed a diagnosis of MALT lymphoma. Awareness of the varied clinical presentation helps in formulating the appropriate therapeutic strategy.

    2014-01-01

    Full Text Available Intravascular large B-cell lymphoma (IVLBL is a rare subtype of diffuse large B-cell lymphoma that resides in the lumen of blood vessels. Patients typically present with nonspecific findings, particularly bizarre neurologic symptoms, fever, and skin lesions. A woman presented with shortness of breath and a chest CT scan showed diffuse interstitial thickening and ground glass opacities suggestive of an interstitial lung disease. On physical exam she was noted to have splenomegaly. The patient died and at autopsy was found to have an IVLBL in her lungs as well as nearly all her organs that were sampled. Although rare, IVLBL should be included in the differential diagnosis of interstitial lung disease and this case underscores the importance of the continuation of autopsies.

    Full Text Available Abstract Background Solitary involvement of the sphenoid sinus has rarely been reported in non-Hodgkin's lymphoma. Isolated oculomotor nerve palsy is uncommon as an initial presentation of malignant tumors of the sphenoid sinus. Case presentation A 53-year-old woman presented with a three-month history of headache and diplopia. Neurological examination revealed complete left oculomotor nerve palsy. Magnetic Resonance Imaging (MRI demonstrated a homogenous soft-tissue lesion occupying the left sphenoid sinus and invading the left cavernous sinus. The patient underwent transsphenoidal biopsy and the lesion was histologically diagnosed as non-Hodgkin's lymphoma, diffuse large B-cell type. Tumor cells were positive for CD20 and negative for CD3. Following six cycles of chemotherapy, the left oculomotor nerve palsy that had been previously observed was completely resolved. There was no enhancing lesion noted on follow-up MRI. Conclusion It is important to recognize that non-Hodgkin's lymphoma of the sphenoid sinus can present with isolated oculomotor nerve palsy, although it is extremely rare. The cranial nerve deficits can resolve dramatically after chemotherapy.

    Mucosa-associated lymphoid tissue (MALT) lymphoma is a low-grade lymphoma that differs from high-grade non-Hodgkin lymphoma both clinically and histologically. The CT appearances of MALT lymphoma are described. Of 40 patients referred with biopsy-proven MALT lymphoma, only seven had not had gastrectomy or chemotherapy prior to CT examination. The CT scans of these seven cases were analysed for the degree and extent of gastric wall thickening, enlargement of abdominal and extra-abdominal lymph nodes, and presence of extranodal disease. In all patients the stomach was distended with oral contrast medium and scans performed at narrow collimation, after intravenous administration of 20 mg hyoscine butylbromide. In six patients focal thickening of the gastric wall was 1 cm or less. One patient had thickening of over 4 cm. There was no enlargement of abdominal or extra-abdominal lymph nodes or extension to adjacent organs. Thus on CT, at presentation, MALT lymphoma results in minimal gastric wall thickening, unlike high-grade non-Hodgkin lymphoma, which typically causes bulky gastric disease, nodal enlargement and extension into adjacent organs. CT is therefore of limited value in monitoring response to treatment. With disease greater than minimal thickening, transformation to a higher grade should be considered. (orig.)

    Full Text Available We report three elderly patients with follicular lymphoma in situ (FLIS each highlighting a unique pattern of disease presentation and progression. The first patient had incidentally detected FLIS with peripheral blood spill and yet had an 11-year uneventful follow up. The second patient with an overt follicular lymphoma (FL developed high-grade transformation in jejunum with FLIS extensively involving the Payers patches. The third patient had a FLIS but that qualified as higher grade and was treated in spite of lack of overt FL mainly because of higher grade and patient subsequently did develop overt FL. The first case of typical FLIS confirms that peripheral blood spill does not connote poor prognosis in FLIS, the second case illustrates that FLIS may colonize mucosa-associated lymphoid tissue as part of homing in process of a disseminated FL and the third case validates the aggressive nature of high-grade FLIS.

    Full Text Available We present a woman referred with underlying non-Hodgkin's lymphoma (NHL masquerading clinically with Guillain-Barré syndrome (GBS like syndrome. At first evaluation, chest CT-Scan along with brain and whole spine MRI were normal. Electrodiagnostic studies were in favor of acute generalized polyradiculoneuropathy. Laboratory evaluation revealed hypoglycorrhachia. She treated with plasmapheresis after two weeks; she was discharged from hospital, but neurological recovery was not complete. After 6 months, she came back with acute onset of weakness in lower limbs, back pain, fever and urinary incontinence. Pinprick and light touch complete sensory loss was found beneath umbilicus. Thoracic MRI with contrast revealed a dorsal epidural mass extending smoothly from T8 to T12 (10 cm with spinal cord compression. She underwent urgent laminectomy for spinal cord decompression. Histological examination revealed small round cell tumor suggestive of malignant T-cell type lymphoma. In cases with Guillain-Barré syndrome presentation, systemic hematologic disorders such as non-Hodgkin's lymphoma should be considered as one of the differential diagnosis of underlying disease.

    Full Text Available Kehai Gao, Hongtao Li, Caihong Huang, Huazhuang Li, Jun Fang, Chen Tian Department of Orthopaedics, Yidu Central Hospital, Shandong, People’s Republic of China Introduction: Anaplastic large cell lymphoma (ALCL is a type of non-Hodgkin lymphoma that has strong expression of CD30. ALCL can sometimes involve the bone marrow, and in advanced stages, it can produce destructive extranodal lesions. But anaplastic large cell lymphoma kinase (ALK+ ALCL with soft tissue involvement is very rare.Case report: A 35-year-old woman presented with waist pain for over 1 month. The biopsy of soft tissue lesions showed that these cells were positive for ALK-1, CD30, TIA-1, GranzymeB, CD4, CD8, and Ki67 (90%+ and negative for CD3, CD5, CD20, CD10, cytokeratin (CK, TdT, HMB-45, epithelial membrane antigen (EMA, and pan-CK, which identified ALCL. After six cycles of Hyper-CVAD/MA regimen, she achieved partial remission. Three months later, she died due to disease progression.Conclusion: This case illustrates the unusual presentation of ALCL in soft tissue with a bad response to chemotherapy. Because of the tendency for rapid progression, ALCL in young adults with extranodal lesions are often treated with high-grade chemotherapy, such as Hyper-CVAD/MA.

    2011-10-01

    BACKGROUND: Primary lymphoma of the breast accounts for 0.04-0.5% of all breast malignancies and approximately 1% of all extranodal lymphomas. For stage IE node-negative disease, involved field radiotherapy is recommended except for very young women in whom the risk of breast cancer is a concern. The rate of complete response for limited stage extranodal marginal B-cell lymphoma is in excess of 90%. CASE REPORT: We report the case of a 62-year-old lady who presented with a unilateral painless palpable right breast lump. She subsequently underwent a trucut biopsy of the lesion. The histology revealed a low-grade B-cell non-Hodgkin\\'s lymphoma (NHL). Immunohistochemistry showed that more than 95% of the cells were B cells which were CD 20+\\/CD 45+ and BC L6+. This confirmed the diagnosis of marginal zone lymphoma. Staging work-up was negative for distant metastases. Serum alkaline phosphatase and lactate dehydrogenase were normal. The patient had no \\'B\\' symptoms. Her final diagnosis was clinical stage IAE NHL, and she was referred for curative radiotherapy. CONCLUSION: Radiation treatment is a safe and extremely effective modality of treatment for early stage I marginal zone B-cell lymphomas of the breast.

    Non-Hodgkin's lymphomas are a varied and complex group of diseases that must be distinguished from Hodgkin's disease. The latter almost always begins in lymph nodes and spreads primarily in an axial fashion; non-Hodgkin's lymphomas may begin either in lymph nodes or in extranodal tissue and can spread both in an axial fashion and centrifugally. Because of changes in pathology terminology and the introduction of a classification using cell surface markers, many prognostic groups of patients with lymphomas have evolved. Therapeutic choices and prognosis are greatly influenced by variations in anatomic sites and extent of disease. Currently, the decisions on management require a balancing of radiation therapy with systemic chemotherapy. In some cases, radiation therapy alone may be sufficient; however, because most patients with non-Hodgkins's lymphomas tend to have advanced disease, a large percentage of patients will be managed with chemotherapy alone or in combination with radiation therapy

    There were cases diagnosed as Adult Lymphomas in our Institute, of which 690 cases were corresponding to Non Hodgkin Lymphomas and 143 cases to Hodgkin's Disease. In matter of staging a percentage upper than 60% belonged to stages III and I V: Nodular sclerosis was the histologically variety of Hodgkin's Disease most frequently found with 42% followed by Mixed Cellularity with 32%. Non Hodgkin lymphomas according its presentation percentage, the 50% were corresponding to intermediate grade, a 20% to high grade, 17% low grade and 13% extranodals lymphomas. A very important is that a 65% of treated patients, abandoned treatment so it would be important stablish necessary measures in order to give them the economical support that allows them to continue the entire therapy, economical factor is the principal reason of treatment abandonment. But the patients who completed treatment with radiotherapy, chemotherapy, had a percentage of cure and surviving similar to those found in the international medical literature. (The author)

    Full Text Available Sinonasal lymphoma is a non-Hodgkin lymphoma (NHL representing 1.5% of all lymphomas. It presents as an unremitting ulceration with progressive destruction of midline sinonasal and surrounding structures. Poor prognosis warrants early treatment although diagnosis is challenging and frequently delayed. It is usually primary in origin and to our knowledge the sinonasal region has never been reported as a sanctuary site in leukaemia/lymphoma relapse. We present a unique case of B-cell ALL (acute lymphoblastic leukaemia with late relapse to the nasal septum as a sinonasal lymphoblastic lymphoma and with genetic support for this as a sanctuary site.

    Sinonasal lymphoma is a non-Hodgkin lymphoma (NHL) representing 1.5% of all lymphomas. It presents as an unremitting ulceration with progressive destruction of midline sinonasal and surrounding structures. Poor prognosis warrants early treatment although diagnosis is challenging and frequently delayed. It is usually primary in origin and to our knowledge the sinonasal region has never been reported as a sanctuary site in leukaemia/lymphoma relapse. We present a unique case of B-cell ALL (acute lymphoblastic leukaemia) with late relapse to the nasal septum as a sinonasal lymphoblastic lymphoma and with genetic support for this as a sanctuary site.

    Full Text Available Abstract Background Mantle cell lymphoma (MCL is an aggressive type of B-cell non-Hodgkin's lymphoma that originates from small to medium sized lymphocytes located in the mantle zone of the lymph node. Extra nodal involvement is present in the majority of cases, with a peculiar tendency to invade the gastro-intestinal tract in the form of multiple lymphomatous polyposis. MCL can be accurately diagnosed with the use of the highly specific marker Cyclin D1. Few cases of mantle cell lymphoma presenting with intussuception have been reported. Here we present a rare case of multiple intussusceptions caused by mantle cell lymphoma and review the literature of this disease. Case presentation A 68-year-old male presented with pain, tenderness in the right lower abdomen, associated with nausea and non-bilious vomiting. CT scan of abdomen revealed ileo-colic intussusception. Laparoscopy confirmed multiple intussusceptions involving ileo-colic and ileo-ileal segments of gastrointestinal tract. A laparoscopically assisted right hemicolectomy and extended ileal resection was performed. Postoperative recovery was uneventful. The histology and immuno-histochemistry of the excised small and large bowel revealed mantle cell lymphoma with multiple lymphomatous polyposis and positivity to Cyclin D1 marker. The patient was successfully treated with Rituximab-CHOP chemotherapy and remains in complete remission at one-year follow-up. Conclusion This is a rare case of intestinal lymphomatous polyposis due to mantle cell lymphoma presenting with multiple small bowel intussusceptions. Our case highlights laparoscopic-assisted bowel resection as a potential and feasible option in the multi-disciplinary treatment of mantle cell lymphoma.

    Intravascular lymphoma (IVL) is a rare extra nodal subtype (usually of B-cell origin) presenting with infiltration of large neoplastic lymphocytes into lumina of blood vessels, leading to vascular occlusion. The early diagnosis is very crucial, however it is usually diagnosed postmortem investigation in most of the cases. A 56-year-old female presented with elevated creatinine level, and anasarca-type edema that superimposed with hard, indurated, erythematous plaques extending to inguinal region, abdomen, anterior aspect of chest, and face. B-cell IVL was confirmed with skin biopsy. The patient had some degree of clinical improvement following chemotherapy. B-cell IVL presenting with anasarca edema was not previously reported in the literature. Even if its rarity, IVL should be considered in the differential diagnosis of renal failure with anasarca edema.

  3. Recent advances in understanding the biology of marginal zone lymphoma

    There are three different marginal zone lymphomas (MZLs): the extranodal MZL of mucosa-associated lymphoid tissue (MALT) type (MALT lymphoma), the splenic MZL, and the nodal MZL. The three MZLs share common lesions and deregulated pathways but also present specific alterations that can be used for their differential diagnosis. Although trisomies of chromosomes 3 and 18, deletions at 6q23, deregulation of nuclear factor kappa B, and chromatin remodeling genes are frequent events in all of them, the three MZLs differ in the presence of recurrent translocations, mutations affecting the NOTCH pathway, and the transcription factor Kruppel like factor 2 ( KLF2) or the receptor-type protein tyrosine phosphatase delta ( PTPRD). Since a better understanding of the molecular events underlying each subtype may have practical relevance, this review summarizes the most recent and main advances in our understanding of the genetics and biology of MZLs.

    A male patient with an exposure keratopathy caused by lagophthalmos. A gold weight was implanted in the right upper eyelid. Eight months later, he presented with erythema and swelling of right upper eyelid. An incisional biopsy was performed, reporting extranodal marginal zone B cell lymphoma. when a tumour at the site of a gold weight implant is refractory to treatment, it is essential to perform an incisional biopsy to establish the histopathological diagnosis. Ocular adnexal lymphomas are relatively common. The presence of foreign material can cause chronic inflammation that could be the stimulus for the development of a lymphoproliferative disorder.

    Full Text Available Abstract Introduction Burkitt lymphoma and B cell lymphomas in childhood may arise in many atypical locations, which on rare occasions can include gastric mucosa. A case of primary gastric Burkitt lymphoma is described in a child presenting as a protein-losing enteropathy, including the direct monitoring of the disease response by sequential endoscopic biopsy and molecular analysis. Case presentation We report a 9-year-old boy who presented with gross oedema, ascites and respiratory distress caused by a protein-losing enteropathy. Initial imaging investigations were non-diagnostic but gastroduodenal endoscopy revealed massive involvement of the gastric mucosa with a primary Burkitt lymphoma. His subsequent clinical progress and disease response were monitored directly by endoscopy and he remains in clinical remission 4 years after initial diagnosis. Conclusions This is the first case report of primary Burkitt lymphoma presenting as a protein-losing enteropathy. The clinical course and progress of the patient were monitored by sequential endoscopic biopsy, histology and molecular analysis by fluorescence in situ hybridisation.

    Full Text Available Non-Hodgkin lymphoma is a common childhood T-cell and B-cell neoplasm that originates primarily from lymphoid tissue. Cutaneous involvement can be in the form of a primary extranodal lymphoma, or secondary to metastasis from a non-cutaneous location. The latter is uncommon, and isolated cutaneous involvement is rarely reported. We report a case of isolated secondary cutaneous involvement from nodal anaplastic large cell lymphoma (CD30 + and ALK + in a 7-year-old boy who was on chemotherapy. This case is reported for its unusual clinical presentation as an acute febrile, generalized papulonodular eruption that mimicked deep fungal infection, with the absence of other foci of systemic metastasis.

    2018-04-01

    Full Text Available Hemophagocytic lymphohistiocytosis (HLH is an uncommon disease that often presents with nonspecific findings. A high index of suspicion is necessary to make a prompt diagnosis and prevent fatal disease. A 45-year-old man presented with fever, hypotension, abdominal pain, nausea, and vomiting. Imaging showed hepatosplenomegaly and laboratory tests revealed pancytopenia, increased ferritin, and a cholestatic pattern of injury with elevated alkaline phosphatase and total bilirubin. Due to a history of Crohn disease, systemic lupus erythematous, and rheumatoid arthritis, the patient was on immunosuppressants, including infliximab. After multiple negative cultures, persistent fever, and days of empiric broad spectrum antibiotics, our differential shifted to fever of unknown origin. A liver wedge biopsy revealed areas of sinusoidal dilatation with enlarged, activated macrophages containing erythrocytes and intracytoplasmic iron, consistent with hemophagocytosis due to HLH. The portal tracts showed mixed lymphoplasmacytic inflammation, a prominent bile ductular reaction, periportal fibrosis, and scattered large cells with occasional binucleation and prominent nucleoli. These cells stained positive for Epstein-Barr virus encoding region in situ hybridization, PAX5, CD15, and CD30, and hepatic involvement by classic Hodgkin lymphoma was diagnosed and determined to be the cause of the HLH and cholestatic pattern of injury. Simultaneously, a bone marrow biopsy showed diffuse involvement by Hodgkin lymphoma with a similar staining pattern. Aggressive treatment failed and the patient succumbed to multiorgan failure. HLH is a rare, potentially fatal disease, with nonspecific signs and symptoms, and should be considered in any patient presenting with fever and pancytopenia, especially if they are immune compromised.

    In this retrospective study, 470 patients with non-Hodgkin's lymphoma (NHL) who had been followed in the Hacettepe University Medical Oncology Department between 1973 and 1990, were evaluated to establish their epidemiologic, clinical and therapeutic characteristics. Out of 470 patients, 302 (62.2%) were male and 168 (37.8%) were female. The ages ranged from 16 to 85, with a median of 44 years. Constitutional symptoms were present in 46.4% of the patients. According to the Working Formulation, low, intermediate, and high-grade lymphomas comprised 33.4%, 54.9%, and 12.7%, respectively. The most common extranodal presentation was gastrointestinal. The chemotherapy regimens most commonly used were CVP (cyclophosphamide, vincristine, prednisone), BCNOP (bleomycin, cyclophosphamide, mitoxantrone, vincristine, prednisone), CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) and CHOP-Bleo (cyclophosphamide, doxorubicin, vincristine, prednisone, bleomycin). The response rates and the survival figures attained with these regimens were not statistically significantly different (P > 0.05). In the Cox multivariate model, pathologic grade, leukopenia, responsiveness to chemotherapy, bone marrow involvement and age were the important factors influencing the disease-free survival, while responsiveness to chemotherapy, age, presence of constitutional symptoms, pathologic grade, extranodal presentation and stage were the important factors influencing the overall survival. The distribution of NHL according to grade and stage was similar to that in western societies, while constitutional symptoms and lymphomas of the small intestine including immunoproliferative small intestinal disease were more common in Turkey.

    Full Text Available Sjögren’s syndrome (SS has the highest incidence of malignant lymphoproliferative disorders transformation among autoimmune diseases. We present a case of extranodal high grade lymphoma of the liver in a 52-year-old patient with long history of SS. Lymphoma manifested with sharp significant pain in the right hypochondrium, weakness, and profuse night sweats. Contrast-enhanced computed tomography scan (CT-scan of the abdomen revealed multiple low density foci with homogeneous structure and clear contours in both lobes of the liver. Histologically, proliferation of medium sized lymphoma cells with round-oval and slightly irregular nuclei with fine chromatin was shown. Immunohistochemical and molecular features of the tumors allowed diagnosis of diffuse large B-cell lymphoma (DLBCL. To exclude secondary liver lesion by non-Hodgkin lymphoma, chest and small pelvis CT-scan, endoscopy of upper and lower gastrointestinal tract and study of bone marrow were performed. After 8 cycles of R-CHOP chemotherapy (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone, the complete remission was achieved, which persists after 45 months of follow-up. Primary hepatic lymphomas are extremely rare, and previously only low-grade hepatic lymphomas have been described in SS. To our knowledge, the patient described here represents the first reported case of DLBCL with primary liver involvement in SS.

    Colonic lymphoma is an uncommon presentation of extranodal lymphoma. Colonic mucosa-associated lymphoid tissue lymphoma is a different entity from gastric mucosa-associated lymphoid tissue lymphoma, and very rare. The presentation and management of colonic mucosa-associated lymphoid tissue are highly variable in the literature. We report the case of a 59-year-old Taiwanese man who underwent a colonoscopy after a positive test for fecal occult blood. His past history included hypertension and hyperthyroidism. The colonoscopy revealed an adenomatous polyp and mucosa-associated lymphoid tissue lymphoma. We successfully performed a polypectomy and endoscopic mucosal resection. The lymphoma was staged according to the Ann Arbor system modified by Musshoff as E-I. Our patient showed no lymphoma recurrence over a 3-year follow-up. Endoscopic mucosal resection for colonic mucosa-associated lymphoid tissue lymphoma without disseminated disease may be feasible. We successfully used colonoscopic treatment without adjuvant therapy to treat early-stage pathogen-free colonic mucosa-associated lymphoid tissue lymphoma.

    Full Text Available We report a rare case of diffuse large B-cell lymphoma (DLBCL of the lacrimal sac in a 50-year-old male. The incidence of primary ocular lymphoma is low and it is considered a rare disease. Moreover, reports of ocular DLBCL are uncommon and the disease remains poorly characterized. Our patient presented for management of osteomyelitis and was incidentally found to have a painless swelling and cyst around his right eye. A PET/CT scan revealed hypermetabolic activity within the lacrimal sac and a subsequent excisional biopsy of the mass yielded histopathology consistent with DLBCL. Consequently, the patient underwent treatment with R-CHOP therapy. The patient responded well to chemotherapy with a substantial shrinkage in tumor burden and the disease remained localized. Herein, we present a rare case of primary ocular lymphoma, highlight the importance of early diagnosis, and review current treatment modalities.

  14. 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.

    AIMS: Gastric MALT (mucosa-associated lymphoid tissue) lymphoma is now recognized as a distinct entity within extranodal non-Hodgkin's lymphoma. The purpose of this study was to describe the radiographic findings in low grade gastric MALT lymphoma. MATERIALS AND METHODS: We retrospectively reviewed the radiographic findings in 22 cases of low-grade gastric MALT lymphoma. The study group consisted of 15 men and seven women (median age 68 years, range 41-91 years). Lesions were designated as infiltrative or polypoid by consensus of two radiologists. Polypoid lesions were categorized by number and size. Anatomical site within the stomach and presence of transpyloric or oesophagogastric extension was determined for each case. The presence of abdominal lymphadenopathy was categorized as regional or distant. The presence of Helicobacter pylori was determined from endoscopic and surgical biopsies. RESULTS: Computed tomography (CT) revealed abnormalities of the stomach in 19 cases of the 21 in which it was performed. There were 14 infiltrative lesions and five polypoid lesions. Of the 14 infiltrative lesions, the mean gastric wall thickness was 2.2 cm (range 0.8-6.0 cm). There were three single and two multiple polypoid lesions (mean size 2.2 cm, range 1.5-2.7 cm). Transpyloric extension was observed in two cases and oesophagogastric extension in one. Abdominal lymphadenopathy was observed in 10 of 21 patients. Helicobacter pylori was found in 19 of 22 cases (86%). CONCLUSION: Low grade B cell gastric MALT lymphomas present with an infiltrative form on CT in about three-quarters of cases and a polypoid pattern in the remainder. Abdominal lymphadenopathy is seen in approximately one-half of cases. There is a high association with Helicobacter pylori. Brown, J.A. 2000. Clinical Radiology 55, 384-389

    Follicular non-Hodgkin's lymphoma (NHL) is a unique subtype of NHL, which is indolent, incurable with a high prevalence of residual mass after treatment, and may transform to more aggressive NHL. The aim of this review is to (1) describe the histological and flow cytometry characteristics of follicular NHL; (2) introduce the Follicular Lymphoma International Prognostic Index 2 (FLIPI-2), which allows better treatment selection and patient stratification for clinical trials; (3) illustrate the classic and atypical ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and positron-emission tomography (PET)/CT appearance of follicular NHL; and (4) characterize the appearance of nodal and extranodal follicular NHL with pathological correlation. Imaging is essential in every step of the management of patients with follicular lymphoma. Overall survival is improved with better predictive tools and new targeted biological therapies. Radiologists should be aware of possible active residual mass, indolent recurrence, transformation, and association with other primary cancers in patients treated for follicular lymphoma.

    Full Text Available Abstract Extranodal natural killer (NK/T-cell lymphoma is an aggressive malignancy of putative NK-cell origin, with a minority deriving from the T-cell lineage. Pathologically, the malignancy occurs in two forms, extranodal NK/T-cell lymphoma, nasal type; and aggressive NK-cell leukaemia. Lymphoma occur most commonly (80% in the nose and upper aerodigestive tract, less commonly (20% in non-nasal areas (skin, gastrointestinal tract, testis, salivary gland, and rarely as disseminated disease with a leukemic phase. Genetic analysis showed mutations of genes involved in the JAK/STAT pathway, RNA assembly, epigenetic regulation, and tumor suppression. In initial clinical evaluation, positron emission tomography computed tomography, and quantification of plasma EBV DNA are mandatory as they are useful for response monitoring and prognostication. In stage I/II diseases, combined chemotherapy and radiotherapy (sequentially or concurrently is the best approach. Conventional anthracycline-containing regimens are ineffective and should be replaced by non-anthracycline-containing regimens, preferably including L-asparaginase. Radiotherapy alone is associated with high systemic relapse rates and should be avoided. In stage III/IV diseases, non-anthracycline-regimens-containing L-asparaginase are the standard. In relapsed/refractory cases, blockade of the programmed death protein 1 has recently shown promising results with high response rates. In the era of effective non-anthracycline-containing regimens, autologous haematopoietic stem cell transplantation (HSCT has not been shown to be beneficial. However, allogeneic HSCT may be considered for high-risk or advanced-stage patients in remission or relapsed/refractory patients responding to salvage therapy. Prognostic models taking into account presentation, interim, and end-of-treatment parameters are useful in triaging patients to different treatment strategies.

    Purpose: Mucosa-associated lymphoid tissue (MALT) lymphoma commonly presents in the gastrointestinal (GI) tract. Supradiaphragmatic MALT lymphoma is less common and its natural history is not well defined. This study was conducted to understand the natural history, to determine the frequency of synchronous disease in the GI tract, and to understand the patterns of disease progression after treatment for supradiaphragmatic MALT lymphoma. Patients and Methods: We retrospectively reviewed the medical records of 39 patients who presented with supradiaphragmatic MALT lymphoma between 1991 and 1997. Results: The median age of patients was 58 years (range, 25-90 years) with 16 male and 23 female patients. The most common primary site was salivary gland followed by ocular adnexa, lung, oral cavity, and others. Sixteen patients underwent esophagogastroduodenoscopy and biopsy (EGD + Bx) and 4 were found to have gastric involvement. Ann Arbor stages were the following: IEA, 17; IIEA, 5, IIEB, 1; and IVA, 16. The initial treatments were: involved field radiation therapy (n = 10), chemotherapy (n = 14), combination of radiation therapy and chemotherapy (n = 9), observation after biopsy (n = 4), antibiotics only (n = 1), and patient refusal of further intervention (n = 1). Seven patients received antibiotics as a part of the initial treatment. Every patient except for 1 was alive at a median follow-up of 39.5 months (range, 3-83 months). Thirty-six patients achieved complete response (CR) to the initial treatment. The actuarial 5-year progression-free survival rate was 83%. Progression of the disease occurred in 4 patients, with 2 in the stomach. Salvage attempts were made to 4 and were successful in 3. Of the 2 patients who relapsed in the stomach, 1 had negative EGD + Bx at the time of initial diagnosis. An EGD + Bx was not done in the second patient. Conclusion: Supradiaphragmatic MALT lymphoma appears to have a favorable prognosis. However, routine evaluation of the stomach

    Purpose: To identify the prognostic factors that specifically predict survival rates of patients with localized aggressive non-Hodgkin's lymphoma (NHL). Methods and Materials: The survey was carried out at 25 radiation oncology institutions in Japan in 1998. The 5-year event-free (EFS) and overall survival rates (OAS) were calculated, and univariate and multivariate analyses were done to identify which of the following factors, namely, gender, age, performance status (PS), serum lactate dehydrogenase (LDH) level, Stage (I vs. II), tumor bulk (maximum diameter), and treatment, were significant from the viewpoint of prognosis. Results: A total of 1141 patients with Stage I and II NHL were treated by the Japanese Lymphoma Radiation Therapy Group between 1988 and 1992. Of them, 787 patients, who were treated using definitive radiotherapy with or without chemotherapy for intermediate- and high-grade lymphomas in working formulation, constituted the core of this study. Primary tumors arose mainly from extranodal organs (71%) in the head and neck (Waldeyer's ring: 36% and sinonasal cavities: 9%). The factors associated with poorer prognosis were age over 60 years old (p < 0.0001), radiation therapy alone (p < 0.0001), PS = 2-4 (p = 0.0011), (sex male, p = 0.0078), a bulky tumor more than 6 cm in maximum diameter (p 0.0088), elevated LDH (p = 0.0117), and stage II (p = 0.0642). A median dose of 42 Gy was delivered mainly to the involved fields. Short-course chemotherapy was provided in 549 (70%) patients. The 5-year OAS and EFS rates for all patients were 71% and 67%, respectively. According to the stage-modified International Prognostic Index, the 5-year EFS of the patients with risk factors from 0 to 1 was 76%, 61% for patients with two risk factors, and 26% for patients with three or more risk factors. Conclusion: Extranodal presentation, especially Waldeyer's ring and sinonasal cavities, is encountered more frequently in Japan than in Western countries. Tumor bulk is

    Extranodal natural killer (NK)/T-cell lymphoma, nasal type, is an uncommon lymphoma associated with the Epstein-Barr virus (EBV). It most commonly involves the nasal cavity and upper respiratory tract. Primary pulmonary NK/T cell lymphoma is extremely rare. If a patient with a NK or T-cell tumor has an unusual reaction to treatment or an unusual prognosis, it is wise to differentiate NK from T-cell tumors. The clinicopathologic characteristics, immunophenotype, EBV in situ hybridization, and T cell receptor (TCR) gene rearrangement of primary pulmonary NK cell lymphoma from a 73-year-old Chinese woman were investigated and the clonal status was determined using female X-chromosomal inactivation mosaicism and polymorphisms at the phosphoglycerate kinase (PGK) gene. The lesion showed the typical histopathologic characteristics and immunohistochemical features of NK/T cell lymphoma. However, the sample was negative for TCR gene rearrangement. A clonality assay demonstrated that the lesion was monoclonal. It is concluded that this is the first recorded case of genuine primary pulmonary NK cell lymphoma. The purpose of the present work is to recommend that pathologists carefully investigate the whole lesion to reduce the likelihood that primary pulmonary NK cell lymphoma will be misdiagnosed as an infectious lesion. In addition, TCR gene rearrangement and clonal analysis, which is based on female X-chromosomal inactivation mosaicism and polymorphisms at PGK and androgen receptor (AR) loci, were found to play important roles in differentiating NK cell lymphoma from T cell lymphoma.

    Full Text Available Abstract Introduction Hypercalcemia is the major electrolyte abnormality in patients with malignant tumors. It can be due to localized osteolytic hypercalcemia or elaboration of humoral substances such as parathyroid hormone-related protein from tumoral cells. In hematological malignancies, a third mechanism of uncontrolled synthesis and secretion of 1-25(OH2D3 from tumoral cells or neighboring macrophages may contribute to the problem. However, hypercalcemia is quite unusual in patients with B-cell non-Hodgkin's lymphoma. Case presentation An 85-year-old Caucasian woman presented with low grade fever, anorexia, abdominal discomfort and fullness in her left abdomen for the last six months. She was mildly anemic and complained of fatigability. She had huge splenomegaly and was hypercalcemic. After correction of her hypercalcemia, she had a splenectomy. Microscopic evaluation revealed a malignant lymphoma. Her immunohistochemistry was positive for leukocyte common antigen, CD20 and parathyroid hormone-related peptide. Conclusion Immunopositivity for parathyroid hormone-related peptide clearly demonstrates that hypersecretion of a parathyroid hormone-like substance from the tumor had led to hypercalcemia in this case. High serum calcium is seen in only seven to eight percent of patients with B-cell non-Hodgkin's lymphoma, apparently due to different mechanisms. Evaluation of serum parathyroid hormone-related protein and 1-25(OH2D3 can be helpful in diagnosis and management. It should be noted that presentation with hypercalcemia has a serious impact on prognosis and survival.

    We describe the case of a 57-year-old man who was referred to us with persistent sore throat, dysphagia, and enlarged tonsils. He had not responded to earlier treatment with antibiotic therapy and other routine measures. In view of the persistent nature of the patient\\'s symptoms and the tonsillar hypertrophy, we decided to perform a tonsillectomy and to send the excised specimens for pathologic analysis. Histologic evaluation identified non-Hodgkin lymphoma in both tonsils. The patient was treated with postoperative chemo- and radiotherapy, and he was free of symptoms during 18 months of follow-up. To the best of our knowledge, only 4 cases of bilateral non-Hodgkin lymphoma of the tonsils have been reported in the English-language literature. We also discuss the importance of histologic analysis of excised tonsil tissue in selected cases.

    Full Text Available Context: Incidence of non-Hodgkin's lymphoma (NHL is increasing in all parts of the world, especially over the past few decades. An insight into the clinical presentation may help in the prevention, control, and treatment of NHL. Aim: To observe the clinicopathological patterns of NHL among patients in Northeast India. Subjects and Methods: A retrospective case study on 100 proven cases of NHL registered at the Regional Institute of Medical Sciences, Manipur, during the period January 2013–May 2017 was conducted, and data were reviewed and analyzed. Statistical Analysis Used: Data were analyzed using SPSS-21 and results were presented in percentages and simple frequency. Results: Majority (43.0% of the patients were in the age group of 41 and 60 years. The mean age was 54.01 ± 18.1 years. Male:female ratio was 1.2:1. The most common presenting symptom was neck swelling (57.0%, and peripheral lymphadenopathy (76.0% was the most common sign. Primary site distribution was nodal (57.0% and extra-nodal NHL (43.0%. Most common nodal site involved was cervical lymph nodes (65.0%, and gastrointestinal tract (17.0% was the most common extranodal subsite. Majority of the patients were in stage II (36.0% at the time of diagnosis. B-cell NHL accounts for 66.0% compared to T-cell lymphoma (23.0%. Diffuse large B-cell lymphoma was the most frequent B-cell lymphoma (45.0%, and anaplastic large cell lymphoma was the most common T-cell variant (15.0%. Conclusions: A thorough insight into the clinical spectrum of NHL is necessary for optimum management and improved treatment outcome.

    A 60-year-old man underwent radiological investigations due to the onset of back pain. Computed tomography (CT) and magnetic resonance imaging (MRI) showed the presence of a paravertebral mass located ahead the body of the third thoracic vertebra. Based on these findings the patient underwent biopsy of the paravertebral mass, which showed the presence of a plasmablastic lymphoma. Therefore, the patient underwent fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography ({sup 18}F-FDG PET/CT) for staging. Before {sup 18}F-FDG injection, the patient had fasted for at least 6 h; at the time of the radiopharmaceutical injection he presented glucose blood levels corresponding to 98 mg/dl. Images were acquired 1 h after intravenous injection of 280 MBq of {sup 18}F-FDG according to the body mass index. PET images were interpreted visually and semiquantitatively by using the maximal standardized uptake value (SUVmax). {sup 18}F-FDG PET/CT showed moderate radiopharmaceutical uptake corresponding to the paravertebral lesion (SUVmax 3.3) and diffuse uptake in the skeleton suspicious for bone marrow neoplastic involvement, with more evident hypermetabolic areas in the left scapula (SUVmax 3.7), right sixth rib (SUVmax 3.5), and left iliac bone (SUVmax 3.4) (Fig. 1). Subsequent bone marrow biopsy confirmed the bone marrow infiltration by plasmablastic cells. Based on these findings, a final diagnosis of plasmablastic lymphoma with bone marrow involvement was performed and the patient was addressed to chemotherapy. Plasmablastic lymphoma is a rare CD20-negative large-cell lymphoma with plasmablastic features occurring primarily in HIV or Epstein-Barr virus positive individuals. Distinguishing this tumor from myeloma could be challenging. The most frequent site of presentation is the oral cavity, whereas extraoral localizations of plasmablastic lymphoma are considered to be very rare and they should be differentiated from extraosseous localization of

    Primary central nervous system lymphoma (PCNSL) is an extranodal Non-Hodgkin's lymphoma that is confined to the brain, eyes, and/or leptomeninges without evidence of a systemic primary tumor. Although the tumor can affect all age groups, it is rare in childhood; thus, its incidence and prognosis in children have not been well defined and the best treatment strategy remains unclear. A nine-year old presented at our department with complaints of diplopia, dizziness, dysarthria, and right side hemiparesis. Magnetic resonance image suggested a diffuse brain stem glioma with infiltration into the right cerebellar peduncle. The patient was surgically treated by craniotomy and frameless stereotactic-guided biopsy, and unexpectedly, the histopathology of the mass was consistent with diffuse large B cell lymphoma, and immunohistochemical staining revealed positivity for CD20 and CD79a. Accordingly, we performed a staging work-up for systemic lymphoma, but no evidence of lymphoma elsewhere in the body was obtained. In addition, she had a negative serologic finding for human immunodeficient virus, which confirmed the histopathological diagnosis of PCNSL. She was treated by radiosurgery at 12 Gy and subsequent adjuvant combination chemotherapy based on high dose methotrexate. Unfortunately, 10 months after the tissue-based diagnosis, she succumbed due to an acute hydrocephalic crisis.

    Full Text Available Evans syndrome (ES is an autoimmune disorder characterized by simultaneous or sequential development of autoimmune hemolytic anemia, immune thrombocytopenia, and/or neutropenia. ES can be classified as a primary (idiopathic or secondary (associated with an underlying disease syndrome. We report a case of ES in an elderly patient in the presence of multiple trigger factors such as recent influenza vaccine, marginal zone lymphoma, and neuroendocrine tumor G1. Whether this association is casual or causal remains a matter of speculation. It is however necessary to have a thorough work-up in a newly diagnosed ES and a more accurate search of miscellaneous factors especially in elderly patients.

The clinical characteristics and the presentation of the symptoms are mainly related to the primary location of the tomour. Approximately 6% of the non-hodgkin lymphomas that affect Waldeyer's ring are MALT lymphomas, affecting most of them to the palatine amygdala. However, according to the reviewed bibliography, the affectation of the palate is rare, being more frequent the orbital location MALT lymphomas follow a relatively indolent clinical course and generally remain localized in their primary extranodal site. Tumors are sensitive to radiation therapy and local treatment. However, dissemination at multiple sites is not infrequent, it may involve extra-ganglionic sites, such as bone marrow, spleen and liver.  Early diagnosis is the basis of a better prognosis, this allows a more adequate treatment. The role of the in-depth clinical study is emphasized and confirmed by a biopsy. It is important the

    Improvements in the classification, staging, and treatment of the lymphomas, complemented by an improved understanding of the biology of these diseases, has led to an improved outcome of therapy for both Hodgkin's disease and many of the non-Hodgkin's lymphomas. The rapid changes that have occurred in this field in the last decade make it timely to review this subject for radiation oncologists in a comprehensive fashion. This course is designed to meet broad educational needs required for understanding these diseases and providing effective care for patients with lymphoma. The faculty includes many leaders from both laboratory and clinical disciplines dealing with lymphomas, who will address a variety of scientific and clinical topics. The morning session will be devoted to Hodgkin's disease, including new concepts in its biology, a review of clinical trials for early stage disease, a discussion of the role of high dose therapy, and description of long term complications of treatment. The afternoon sessions will be devoted to the non-Hodgkin's lymphomas, including new concepts in pathology and biology, a description of specific entities including the low grade lymphomas, MALT lymphomas, extranodal lymphomas, intermediate grade lymphomas, mantle cell lymphomas, and summary discussions of the role of radioimmuno-therapy and high dose therapy. Although the role of radiation therapy in the management of patients with lymphoma has changed dramatically in the past two decades, radiation remains the most effective single agent for the treatment of these diseases and it is especially important for radiation onologists to keep abreast of these new concepts. This course has been designed to achieve that goal

    The previously designated malignant histiocytosis (MH) may include lymphoid neoplasms of T-cell lineage as well as patients with benign virus-associated hemophagocytic syndrome (VAHS). In this study, the association of Epstein-Barr virus (EBV) with T cell lymphomas which present with clinicopathologic features indistinguishable from malignant histiocytosis (MH) was investigated further. Four adult patients, three women and one man, were admitted because of fever, cutaneous lesions, hepatosplenomegaly, and jaundice. Laboratory examinations revealed pancytopenia, abnormal liver functions and coagulopathy. All patients ran a fulminant course terminating in a hemophagocytic syndrome within 1 month. Immunophenotypic study, Southern blot analysis, and in situ hybridization were performed on the specimens obtained from the four patients. The biopsy-necropsy specimens from skin, liver, spleen, and bone marrow showed infiltration of atypical large cells with reactive histiocytosis and florid hemophagocytosis activity. Based on the clinical and histologic findings, these cases would have been designated as MH by previous criteria. Immunophenotypic, Southern blot, and in situ hybridization studies, however, showed clonotypic proliferation of EBV genomes in the nuclei of the large atypical cells that expressed T-cell antigens. Therefore, these patients should be diagnosed as a recently described EBV-associated peripheral T-cell lymphoma (EBV-PTCL). EBV-PTCL may present with a fulminant hemophagocytic syndrome indistinguishable from the previously designated MH. This finding represents a step forward in our changing concept regarding MH, some of which only recently has been suggested to be of T-cell lymphoma origin. Differentiation from benign VAHS is clinically important. Features useful in this distinction are tabulated and discussed.

    Lymph node metastasis with extranodal extension represents one of the most important adverse prognostic factors for survival in patients with head and neck squamous cell carcinoma. We propose that extranodal extension occurs to differing extents. The aim of this study was to determine the prognostic significance of extranodal extension in patients with head and neck squamous cell carcinoma. Two hundred and ninety-eight patients with head and neck squamous cell carcinoma who underwent surgical resection and neck dissection were included. Cervical lymph nodes were classified into four categories: (i) pathological N negative, (ii) extranodal extension negative, (iii) non-surgical extranodal extension and (iv) surgical extranodal extension. Lymph node metastases were detected in 67.1% of laryngeal/hypopharyngeal cancer patients and 52.7% of oral cancer patients. The 3-year disease-specific survival rates for patients in the pathological N negative, extranodal extension negative, non-surgical extranodal extension and surgical extranodal extension groups were 90.9%, 79.6%, 63.8% and 48.3%, respectively. In laryngeal/hypopharyngeal cancer patients, surgical extranodal extension was associated with a significantly poorer disease-specific survival than a pathological N negative, extranodal extension negative or non-surgical extranodal extension status. In oral cancer patients, no significant differences were observed between the non-surgical and surgical extranodal extension groups. However, non-surgical extranodal extension was associated with a poorer disease-specific survival than a pathological N negative or extranodal extension negative status. Surgical extranodal extension was a poor prognostic factor in patients with head and neck squamous cell carcinoma. The prognostic significance of surgical extranodal extension differed between laryngeal/hypopharyngeal and oral cancer patients. The clinical significance of surgical extranodal extension was much greater for

    2002-01-01

    FDG PET is a functional imaging modality whose ability to detect lesions is directly based on a change of the glycolytic metabolism of targeted tissues, may be advantageous over other techniques. Combined with excellent image quality, high spatial resolution, and whole body imaging capability, it has become popular as a new approach in the evaluation of patients with various malignancies. Initial staging of nodal and extranodal lymphoma using FDG PET has been proven to be at least equal or superior to conventional imaging modalities. For the assessment of treatment responsiveness, FDG PET has a major impact on the management of patients in differentiating residual lymphoma from treatment related benign changes. Residual FDG uptake after the completion of chemotherapy is a good predictor of early relapse. However, it seems that the absence of FDG uptake in tumor mass may not exclude minimal residual disease causing later relapse. In the early evaluation of treatment response only after a few cycles of chemotherapy, FDG PET may have a promising role in identifying non-responders who could benefit from a different treatment strategy. At present, FDG PET appears to be the cost-effective, diagnostic modality of choice in the management of lymphoma patients. The role of FDG PET based-systems in terms of affecting long-term prognosis and survival benefit should be further elucidated in future prospective studies

    Central airway obstruction (CAO) may be caused by various etiologies. However, conventional chest X-rays are rarely diagnostic for patients with CAO. We here described a 64-year-old asymptomatic female with tracheal mucosa-associated lymphoid tissue lymphoma discovered on spirometric findings during a complete physical examination. The plateau of forced expiratory flow was consistent with CAO. A decreased peak expiratory flow rate was noted at least 3 years before the diagnosis, and was attributed to an insufficient effort by the patient. Impulse oscillometric measurements, which were taken during quiet breathing and were effort-independent, suggested elevated respiratory resistance. These abnormalities completely disappeared after radiation therapy. The addition of impulse oscillometry to spirometry may be useful for screening CAO in routine health examinations.

    Full Text Available The recent World Health Organization (WHO classification defines mantle cell lymphoma (MCL as a distinct entity characterized by a unique immunophenotype and a molecular hallmark of chromosomal translocation t(11;14(q13;q32. We report an unusual case of an advanced stage of CD5 negative MCL with a blastoid variant with a massive bone marrow (BM necrosis as an initial presenting feature, with no adenopathy or hepatosplenomegaly. The pathologic features showed blastoid variant of MCL and flow cytometry showed that the tumor cells were CD5−, CD19+, CD20+, FMC-7+, CD23−, and lambda light chain restricted. Chromosomal analysis, using karyotype and fluorescent in situ hybridization (FISH, demonstrated karyotypic abnormalities in addition to the t(11;14. Our case study may be reported as a unique case of CD5− blastic MCL with unusual presentation and findings which made the diagnosis of MCL difficult.

    IgG4-related lymphadenopathy with increased numbers of Epstein-Barr virus (EBV)-infected cells has been reported but not fully described. We analyzed 31 cases of IgG4-related lymphadenopathy and 24 cases of extranodal IgG4-related diseases for their possible relationship with EBV. Other types of reactive lymph nodes (22) and angioimmunoblastic T-cell lymphoma (AITL) (10) were also studied for comparison. EBV-encoded RNA (EBER) in situ hybridization revealed EBER(+) cells in 18 of 31 cases (58%) of IgG4-related lymphadenopathy. Increased EBER(+) cells were found in only 4 of 22 (18.1%) non-IgG4-related reactive lymphoid hyperplasia in patients of a similar age (P=0.002) and in only 5 of 24 (21%) extranodal IgG4-related biopsies (P=0.006). Interestingly, all patients with EBER(+) progressively transformed germinal center-type IgG4-related lymphadenopathy had systemic lymphadenopathy and/or extranodal involvement. AITL also is associated with EBV, and IgG4-related lymphadenopathy sometimes mimics the morphology of AITL; however, the number of IgG4(+) cells in AITL was significantly less than that in IgG4-related lymphadenopathy (Pdisease; however, there was not a significant difference between the EBER(+) and EBER(-) cases. In conclusion, the presence of increased numbers of EBV-infected cells in IgG4-related lymphadenopathy, compared with other reactive lymphadenopathy or extranodal IgG4-related disease, suggests that there may be a relationship at least between nodal IgG4-related disease and EBV. It is important to avoid overdiagnosing these cases as malignant lymphomas or EBV-related lymphoproliferative disorders.

    We present a case of a 60-year-old woman with history of follicular lymphoma in remission presenting for an 18F-fluorodeoxyglucose positron emission tomography/computed tomography for suspected recurrence. Imaging showed widespread hypermetabolic lymphadenopathy consistent with lymphoma recurrence. A 3-month 18F-fluorodeoxyglucose positron emission tomography/computed tomography follow-up after chemotherapy showed resolution of hypermetabolic lymphadenopathy but multiple new hepatic lesions and a new subtle rectal lesion. Biopsies of both hepatic and rectal lesions revealed new diagnosis of metachronous high-grade small-cell carcinoma.

    Autologous hematopoietic cell transplantation (AHCT) is a routinely used procedure in the treatment of adult patients presenting with multiple myeloma (MM), Hodgkin lymphoma (HL) and various subtypes of non-Hodgkin lymphoma (NHL) in upfront and relapsed/refractory settings. Successful hematopoietic progenitor cell mobilization (HPCM) and collection are the rate limiting first steps for application of AHCT. In 2015, almost 1700 AHCT procedures have been performed for MM, HL and NHL in Turkey. Although there are recently published consensus guidelines addressing critical issues regarding autologous HPCM, there is a tremendous heterogeneity in terms of mobilization strategies of transplant centers across the world. In order to pave the way to a more standardized HPCM approach in Turkey, Turkish Society of Apheresis (TSA) assembled a working group consisting of experts in the field. Here we report the position statement of TSA regarding autologous HPCM mobilization strategies in adult patients presenting with MM and lymphoma. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Primary malignant lymphoma of bone, so-called Parker-Jackson reticulosarcoma, is a rare form of extranodal lymphoma with a relatively good prognosis. It often corresponds to B-cell lymphoma of high-grade malignancy. We report a case of mu lambda immunoblastic lymphoma showing two distinctive features: an abundant reactive T-lymphocytic population and unusual intra-cytoplasmic inclusions. These inclusions were PAS positive and consisted of monotypic mu lambda immunoglobulin localized in peculiar aggregates of rough endoplasmic reticulum. Their morphological appearances resembled the well-documented inclusions described in some varieties of non-Hodgkin's lymphoma.

    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.

  9. The role of hematopoietic SCT in adult Burkitt lymphoma.

    2013-05-01

    Adult Burkitt lymphoma (BL) is an aggressive disease characterized by frequent extranodal presentation, bulky disease and a rapid clinical course. Although intensive chemotherapeutic regimes result in long-term disease-free survival in most patients, a significant proportion of patients will have high-risk disease that may be refractory or that will relapse. In these patients, the role of hematopoietic SCT is not well defined, especially in the era of modern chemoimmunotherapy. Upfront auto-SCT has been reported to be feasible in patients who have high-risk features at presentation, and in whom it is a clinical option. In patients with relapsed disease, auto-SCT can result in a PFS of 30-40%. Allo-SCT is an option in relapsing patients with a sibling or matched related donor who may not be eligible for, or may have previously received, an auto-SCT; the role of RIC and T-cell depletion is not well defined. Disease status at transplant is the most significant predictor of outcome in patients undergoing SCT. Here we review the available evidence pertaining to SCT in patients with BL, including in those who are HIV positive (HIV+) and those with B-cell lymphoma unclassified (BCLU). Prospective studies in the era of modern intensive chemoimmunotherapeutic regimes are required to delineate the precise role of transplantation for BL. Developments in molecular diagnostics, incorporation of FDG-PET and minimal residual disease monitoring along with new therapies may further assist in refining treatment algorithms.

    Full Text Available Primary cutaneous follicle center lymphoma (PCFCL is characterized by a proliferation of follicle center cells in the skin. A definitive diagnosis is frequently delayed because of difficulties in interpretation of the histopathologic findings. It has an excellent prognosis with a 5-year survival over 95% and its risk of transformation has not been established. We describe a case report of man with a gastric diffuse large B-cell lymphoma (DLBCL referred to our clinic because of nodules in the back that had gradually developed over a period of 10 years. A biopsy performed 3 years before was interpreted as reactive follicular hyperplasia. A new skin biopsy revealed a diffuse large B-cell lymphoma and immunoglobulin heavy chain gene rearrangements from the initial skin biopsy (PCBCL and the DLBCL gastric biopsy were studied by polymerase chain reaction and an identical clonal rearrangement was detected which was highly suggestive of a transformation lymphoma.

    Somatostatin receptor (SSTR) scintigraphy and gallium-67 citrate ({sup 67}Ga) scintigraphy have been used for visualisation of Hodgkin's lymphoma and non-Hodgkin's lymphoma. However, experience with B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT) type is very limited. The aim of this study was to prospectively compare the {sup 67}Ga scintigraphy results with those obtained by {sup 111}In-DOTA-dPhe{sup 1}-Tyr{sup 3}-octreotide ({sup 111}In-DOTA-TOCT) and {sup 111}In-DOTA-lanreotide ({sup 111}In-DOTA-LAN) scintigraphy in patients with proven MALT-type lymphoma. Comparative scintigraphic examinations using {sup 67}Ga, {sup 111}In-DOTA-TOCT and {sup 111}In-DOTA-LAN were performed in 18 patients (11 female and 7 male, median age 64{+-}15 years) with histologically verified MALT-type lymphomas of various origin.

    Full Text Available Introduction. Intussusception is a rare cause of bowel obstruction in adults and is usually associated with an underlying pathology, benign, or malignant. This is a report of a case of jejunojejunal intussusception secondary to non-Hodgkin’s B-cell lymphoma in an adult patient. Case Presentation. A 74-year-old male with no previous significant medical history presented with symptoms of acute intestinal obstruction. A CT scan of the abdomen and pelvis revealed 2 areas of jejunojejunal intussusception, which were surgically managed successfully. Histopathological examination of the specimen revealed the presence of high grade diffuse large B-cell-type non-Hodgkin’s lymphoma, and the patient was referred to the oncology team for further management. Discussion. B-cell lymphoma is a rare but well-documented cause of intussusception in adults, with most cases being at the ileocolic region. We present a rare case of jejunojejunal intussusception as the initial presentation of non-Hodgkin’s B-cell lymphoma in an adult patient.

    Hodgkin lymphoma (HL) treatment protocols for children, adolescents and young adults traditionally differ, but the biological and clinical justification for this remains uncertain. We compared age-dependent clinical presentation and treatment and outcome for 1072 classical HL patients 0-24 years diagnosed in Denmark (1990-2010) and Sweden (1992-2009) in pediatric (n = 315, Denmark clinical characteristics was assessed with Pearson's chi 2 -test and Mantel-Haenszel trend test. The Kaplan-Meier method was used for survival analyses. Hazard ratios (HR) were used to compare the different treatment groups and calculated using Cox regression. Children (0-9 years) less often presented with advanced disease than adolescents (10-17 years) and young adults (18-24 years) (stage IIB-IV: children 32% vs. adolescents 50%, and adults 55%; p clinical presentation suggesting a rationale of harmonized treatment for these groups. Both adult and pediatric protocols provided high OS with no significant difference between the departments. The less frequent use of radiotherapy in Danish pediatric patients corresponded to a lower EFS, but comparable OS in all groups confirmed effective rescue strategies for the relapsing patients.

    Over a 15-year period, 485 cases of Burkitt's lymphoma (BL) mainly from the southern half of Ghana, were referred to the Burkitt's Tumour Project in Accra, Ghana. From an analysis of the numbers of cases referred each year, the sites of tumour involvement, and the age and sex frequencies, it was concluded that: (i) the number of cases of BL diagnosed in Ghana has decreased progressively over the last 15 years; the number of newly diagnosed cases is now only about one half of what it was 10 years ago; (ii) the male/female ratio has remained practically unchanged over this period; (iii) there has been an overall increase in patients presenting with abdominal disease and a decrease in those presenting with facial disease. This change was particularly apparent in males, in whom the proportion of cases with abdominal disease has more than doubled; (iv) there has been a progressive increase in age at presentation for both males and females over the 15-year period. The possible implications of, and reasons for the above findings are discussed.

    Objective: to describe the main imaging findings of non-Hodgkin's lymphoma presenting as a single liver mass. Materials and methods: a retrospective study was developed with analysis of cases where a single liver mass was observed at ultrasonography, computed tomography and magnetic resonance imaging, and histologically diagnosed as non-Hodgkin's lymphoma. The studies were reviewed by two observers in consensus. Results: three male patients in the fifth decade of life, with non-specific clinical manifestations and single liver mass diagnosed as non-Hodgkin's lymphoma were identified. A hepatic lesion with target sign was observed at ultrasonography in all of the cases. At computed tomography, all the patients presented a heterogeneous, hypodense mass with a ring enhancement. At magnetic resonance imaging, the lesions were heterogeneous and hypointense on T1-weighted and hyperintense on T2-weighted images. Additionally, a ring enhancement was observed in all of the cases after contrast injection. At the moment of the diagnosis, none of the patients presented lymphadenomegaly or involvement of other solid viscera. Conclusion: the diagnosis of hepatic lymphoma should be considered in the presence of a ring-enhanced single liver mass. (author)

    2014-06-01

    Full Text Available Prostate cancer typically metastasizes to bones and regional lymph nodes. Generalized lymphadenopathy is a rare manifestation of metastatic prostate cancer. We report a case of prostate cancer in a 65-year-old male with initial presentation of generalized lymphadenopathy and no urinary symptoms. Lymph node biopsy revealed metastatic adenocarcinoma, and immunohistochemical staining was positive for prostate-specific antigen (PSA compatible with a prostatic origin. Directed biopsy confirmed that the tumor originated in the prostate. Therefore, the prostate should be considered a possible origin of metastatic adenocarcinoma in men, and presentations consistent with generalized lymphadenopathy cannot exclude a diagnosis of prostate cancer.

    Full Text Available BACKGROUND Cancer can cause activation of coagulation in many ways and there is definite evidence of abnormalities in haemostatic mechanism which is seen by the presence of one or more circulating markers of haemostatic activation & this is found to be potentiated by the release of tissue factors or procoagulants from normal tissue destructions during tumour development. OBJECTIVES • To evaluate the range of different types of haemostatic abnormalities in haematological and epithelial malignancies, especially the head and neck epithelial malignancies. • To look for the differences in the grades of these abnormalities in metastatic & non-metastatic malignancies. • To understand the prognostic value of routine tests of coagulation while predicting the outcome of the patient. • MATERIALS AND METHODS The study was conducted in the Department of Pathology, Gauhati Medical College & Hospital, Guwahati from July 2004 to June 2005. 70 cases comprising of head and neck epithelial malignancies, leukaemias and lymphomas without clinical presentation of haemorrhage or thrombosis were selected and coagulation profiles were seen. RESULTS AND OBSERVATION Out of 70 cases of both sexes & different age groups prior to therapeutic intervention, metastatic cases were 22, non-metastatic cases were 29, and 19 cases belonged to leukaemias and lymphomas. The commonest age group affected was 51–60 yrs. and male: female was 3.7: 1. The most frequent abnormality was 41 cases (58.57% of FDP positivity in the serum followed by 36 cases (51.43% of hyperfibrinogenaemia; 32 cases (45.71% shortened bleeding time, etc. DISCUSSION Activated coagulation in cancer leads to increased fibrin deposition stimulated by the destroyed tissues; increased FDPs being a strong marker of coagulation and fibrinolytic activation; increased platelet aggregation by the micro vesicles shed by tumour cells; prolonged PT & APTT being well known markers for disseminated intravascular

    Full Text Available Introduction: The primary nasal lymphoma is an uncommon extranodal tumor and represents 0.44% of all Extranodal lymphomas in this region. The primary nasal lymphoma derives from the T-lineage in nearly 75% of the cases. Objective: To describe a case of nasosinusal lymphoma of T Natural Killer cells, attended in the Clinical Hospital of the Federal University of Goiás. Case Report: 48-year-old female patient with diffuse tumefaction in the left hemiface of firm-elastic consistency and painful upon digital compression. Face sinuses tomography identified a total maxillary veiling to the left and some posterior ethmoidal cells. With the diagnostic hypothesis of a tumor affection, we opted for the surgical removal via a transmaxillary approach and the material was sent for biopsy. The histopathological exam diagnosed a highly necrotic tumor of angiocentric pattern, polymorphic and atypical lymphoid population (T /NK Lymphoma; with the prognosis, the patient was submitted to chemical therapy with total regression of the facial edema. Final Comments: The otorhinolaryngologist must be attentive as regards the existence of lymphomas among the nasosinusal diseases, because the early diagnosis improves the survival as it prevents metastases, growth and local destruction.

    Crystal-storing histiocytosis (CSH) is an uncommon finding in lymphoplasmacytic disorders that presents histiocytes with abnormal intralysosomal accumulations of immunoglobulin light chains as crystals of unknown etiology. A 38-year-old woman with antiphospholipid syndrome had a surgical lung biopsy because of multiple lung mass lesions. In a right middle lobe lesion, lymphoplasmacytic cells had a monocytoid appearance, destructive lymphoepithelial lesions, and positive immunoglobulin heavy chain (IGH) gene rearrangements. A right upper lobe lesion manifested proliferating rounded histiocytes with abundant, deeply eosinophilic cytoplasm and negative IGH gene rearrangements. Electron microscopy and mass spectrometry revealed a case of pulmonary CSH: abnormal proliferation of the immunoglobulin κ chain of a variable region that may be crystallized within plasma cells and histiocytes. We report a rare case of localized pulmonary CSH complicating pulmonary mucosa-associated lymphoid tissue lymphoma with multiple mass lesions. We demonstrate advances in the understanding of the pathogenesis of CSH by various analyses of these lesions. Copyright © 2017 Elsevier Inc. All rights reserved.

    Radiation therapy (RT) is the most effective single modality for local control of Hodgkin lymphoma (HL) and an important component of therapy for many patients. These guidelines have been developed to address the use of RT in HL in the modern era of combined modality treatment. The role of reduced volumes and doses is addressed, integrating modern imaging with 3-dimensional (3D) planning and advanced techniques of treatment delivery. The previously applied extended field (EF) and original involved field (IF) techniques, which treated larger volumes based on nodal stations, have now been replaced by the use of limited volumes, based solely on detectable nodal (and extranodal extension) involvement at presentation, using contrast-enhanced computed tomography, positron emission tomography/computed tomography, magnetic resonance imaging, or a combination of these techniques. The International Commission on Radiation Units and Measurements concepts of gross tumor volume, clinical target volume, internal target volume, and planning target volume are used for defining the targeted volumes. Newer treatment techniques, including intensity modulated radiation therapy, breath-hold, image guided radiation therapy, and 4-dimensional imaging, should be implemented when their use is expected to decrease significantly the risk for normal tissue damage while still achieving the primary goal of local tumor control. The highly conformal involved node radiation therapy (INRT), recently introduced for patients for whom optimal imaging is available, is explained. A new concept, involved site radiation therapy (ISRT), is introduced as the standard conformal therapy for the scenario, commonly encountered, wherein optimal imaging is not available. There is increasing evidence that RT doses used in the past are higher than necessary for disease control in this era of combined modality therapy. The use of INRT and of lower doses in early-stage HL is supported by available data. Although the

In a review of 231 cases of malignant lymphoma (87 Hodgkin lymphoma and 144 non-Hodgkin lymphoma) occurring in Iraqi children, 7 cases (5% of NHLs) were classified as EBV+ DLBCL. Six children presented with nodal disease, and 1 presented with extranodal localization (bone). In all cases, the disease was at an advanced clinical stage (III/IV). Evidence of immunodeficiency (Evans syndrome and selective IgA deficiency) was observed in a single case. Two cases were "monomorphic" with immunoblastic histology, and 5 cases were "polymorphic" with histologic aspects reminiscent of nodular lymphocyte-predominant Hodgkin lymphoma (2 cases) and of CD30+ classical Hodgkin lymphoma (3 cases). In all cases, tumor cells were EBV infected (EBER+/LMP-1+), were medium-large B-cells (CD20+/CD79a+/PAX-5+/BOB-1+/OCT-2+) of non-germinal center (non-GC) origin (CD10-/MUM-1+), and had high proliferative activity (50%-70%). Chromosomal translocations involving BCL2, MYC, and IGH genes were not observed. IGH monoclonality could be demonstrated in 3 of 3 investigated cases. Six cases of EBV-negative DLBCL (4% of NHL) were present in the same series. All had monomorphic histology with centroblastic/immunoblastic morphology; 3 cases were of GC type and 3 of non-GC type. Our findings indicate that in Iraq, DLBCLs are 9% of NHLs. Moreover, 2 different types of the disease do exist; the EBV-positive cases, with strong histologic and immunohistochemical resemblance with EBV+ DLBCL of the elderly, and the EBV-negative cases, which are similar to the pediatric DLBCL usually observed in Western populations.

    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.

    Purpose: Among extranodal lymphomas, orbital mucosa-associated lymphoid tissue (MALT) lymphoma is a relatively rare presentation. We performed a review to ascertain treatment efficacy and toxicity of radiation therapy for orbital MALT lymphoma. We also evaluated changes in visual acuity after irradiation. Methods and Materials: Thirty patients with orbital MALT lymphoma underwent radiation therapy with curative intent. Clinical stages at diagnosis were stage I{sub E}A in 29 patients and stage II{sub E}A in 1 patient. Total doses of 28.8 to 45.8 Gy (median, 30 Gy) in 15 to 26 fractions (median, 16 fractions) were delivered to the tumors. Results: All irradiated tumors were controlled during the follow-up period of 2 to 157 months (median, 35 months) after treatment. Two patients had relapses that arose in the cervical lymph node and the ipsilateral palpebral conjunctiva outside the radiation field at 15 and 67 months after treatment, respectively. The 5-year local progression-free and relapse-free rates were 100% and 96%, respectively. All 30 patients are presently alive; the overall and relapse-free survival rates at 5 years were 100% and 96%, respectively. Although 5 patients developed cataracts of grade 2 at 8 to 45 months after irradiation, they underwent intraocular lens implantation, and their eyesight recovered. Additionally, there was no marked deterioration in the visual acuity of patients due to irradiation, with the exception of cataracts. No therapy-related toxicity of grade 3 or greater was observed. Conclusions: Radiation therapy was effective and safe for patients with orbital MALT lymphoma. Although some patients developed cataracts after irradiation, visual acuity was well preserved.

    Full Text Available Non-Hodgkin's lymphomas (NHLs embody a diverse group of malignancies that originate from the lymphoid system. NHL often exhibit in an extranodal pattern, pertaining to the head and neck region. Intraoral sites are much less frequent, accounting for approximately 3.5% of all oral malignancies. Although the exact cause of NHL still remains inconspicuous, however, research has focused on some factors that may contribute to the development of lymphoma, including genetic factors, impaired immune system and viruses, such as HIV or EBV. Clinically, the bony lesion may present as localized or diffuse swelling, with low-grade pain, sweating, unexplained weight loss, fever, etc. Radiographically, these lesions resemble osteomyelitis or other malignancies creating a diagnostic dilemma. Microscopically, diffused lymphomas consist of large tumor cells with large nuclei that are more than twice the size of lymphocytes which may either exhibit centroblastic or immunoblastic features. Here, we report a rare case of NHL affecting the jaws of a 60-year-old male patient.

    Intravascular lymphoma is a rare subtype of extranodal Non-Hodgkin's lymphoma. Its prognosis is poor in a high percentage of cases due to its insidious appearance and low clinical suspicion. Its diagnosis is usually only reached after an autopsy. It may affect different organs as a whole or only one organ. It is extremely rare that the lung is the only damaged organ. Its diagnosis depends of the clinician's suspicion and proper evaluation with imaging studies as well as correct selection of the organ to be biopsied. When detected on time, the treatment of choice is a combination of a series of chemotherapy associated to a monoclonal antibody (anti-CD20). We present the case of a male patient who underwent a positron emission tomography-computed tomography with 2-[F-18]-fluoro-2 deoxy-D-glucose (FDG) due to symptoms suggestive of a lymphoproliferative disease with no clear structural abnormalities. The images led to a diagnosis of pulmonary intravascular large B cell lymphoma. Copyright © 2012 Elsevier España, S.L. and SEMNIM. All rights reserved.

Worldwide, PTCLs represent approximately 12% of all NHLs and the 2008 World Health Organization (WHO classification includes over 20 biologically and clinically distinct T/NK-cell neoplasms that differ significantly in presentation, pathology, and response to therapy. 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

    International Prognostic Index (IPI) incorporates several independent prognostic variables into risk groups as a basis for the assessment of outcome particularly useful for advanced disease. The success of curative RT is contingent upon the presence of localized disease with favorable prognostic factors, small bulk disease and delivery of a tumoricidal RT dose (30 - 35 Gy) to a field with no critical dose-limiting tissue tolerances. The current evidence indicates that locoregional RT for stage I-II low grade lymphoma results in approximately 50% prolonged (10- 20 years) failure free rate and possible cure. The standard management for stage I-II intermediate and high grade lymphoma, both nodal and extranodal presentation, is combined modality therapy (CMT) using an anthracycline-based chemotherapy followed by involved field RT. The two recently completed trials ECOG (ASCO 95) and SWOG (ASCO 96) have confirmed the benefit of RT in CMT protocols as compared to chemotherapy alone strategies. Combination chemotherapy is the standard management of advanced intermediate and high grade lymphoma and no regimen has been proven to the superior to CHOP. Overall complete response, relapse-free and overall survival rates of approximately 75%, 50% and 40% are achievable. Patients with a worse prognosis can be identified based upon multiple adverse presentation factors (IPI index) although it is not yet clear that current intensive therapy strategies with/without stem cell/marrow support provide survival benefit. The need for additional therapy e.g. CNS prophylaxis or local RT is determined by presentation characteristics or degree of response to chemotherapy

    Hyponatraemia is a very common electrolyte abnormality with varied presenting features depending on the underlying cause. The authors report the case of a 75-year-old, previously fit, gentleman who presented with weight loss, lethargy and blackouts. He required four admissions to the hospital over an 8-month period. Investigations revealed persistent hyponatraemia consistent with a diagnosis of syndrome of inappropriate antidiuretic hormone secretion, macrocytic anaemia and partial hypopituitarism. Unfortunately, all other investigations that were performed failed to identify the underlying cause and a diagnosis of intravascular large B-cell lymphoma was only confirmed following postmortem studies. The authors recommend that endocrinologists should be involved at the outset in the management of patients with persistent hyponatraemia and that intravascular large B-cell lymphoma should be considered in the differential diagnosis of hyponatraemia.

    Primary central nervous system lymphoma (PCNSL) is a rare form of extranodal non-Hodgkin's lymphoma with continuously increasing incidence in both immunosuppressed and immunocompetent individuals. PCNSL is a very aggressive tumor with a poor outcome, and its clinical outcome is much worse than for nodal lymphomas. Differently from lymphomas arising in lymph nodes or in other extranodal sites, the treatment of PCNSL remains very unsatisfactory. Current biologic knowledge of PCNSL is still limited and several fundamental questions remain to be answered. This is mainly due to the paucity of PCNSL material for adequate translational research. With the aim of providing biologic material to investigators interested in PCNSL, we have implemented a virtual tissue bank (VTB) for PCNSL in immunocompetent patients. After registration, the VTB is accessible via any web browser at www.ielsg.org. Only anonymous data are centralized at the website of the International Extranodal Lymphoma Study Group, whilst the pathologic material is maintained at the local pathology institutes. (c) 2007 S.

    Full Text Available Cutaneous T cell lymphomas (CTCLs are a heterogeneous group of extranodal non-Hodgkin’s lymphomas that are characterized by a cutaneous infiltration of malignant monoclonal T lymphocytes. They typically afflict adults with a median age of 55 to 60 years, and the annual incidence is about 0.5 per 100,000. Mycosis fungoides, Sézary syndrome, and primary cutaneous peripheral T cell lymphomas not otherwise specified are the most important subtypes of CTCL. CTCL is a complicated concept in terms of etiopathogenesis, diagnosis, therapy, and prognosis. Herein, we summarize advances which have been achieved in these fields.

    A case is presented of an 85 year-old Caucasian female with lymphoma that recurred in the orbit (secondary ocular adnexal lymphoma). The orbital tumour was a diffuse large B-cell lymphoma according to the REAL classification (Revised European-American Lymphoma Classification). Orbital lymphomas are predominantly B-cell proliferations of a variety of histological types, and most are low-grade tumours. Patients are usually middle-aged or elderly, and it is slightly more common in women. A palpable mass, proptosis and blepharoptosis are the most common signs of presentation.

    Primary cutaneous lymphoma (PCL) is the second most common type of extranodal non-Hodgkin lymphoma, including both cutaneous T-cell and B-cell lymphomas. PCL comprises numerous subtypes and thus has myriad clinical presentations in the skin and subcutaneous tissues. Accurate classification and staging are important for making treatment recommendations for PCL and will further impact patient prognosis significantly. We review the role of fluorine-18-fluorodeoxyglucose (F-FDG) PET (F-FDG PET) and F-FDG PET with computed tomography (CT) in the diagnosis, staging, tumor biological evaluation, treatment response assessment, and early recurrence surveillance of PCL. Although F-FDG PET and PET/CT do not seem to adequately distinguish the plaque, patch, or erythroderma cutaneous lesions of PCL, the imaging modalities are superior to CT, MRI, and other nuclear medicine methods in detecting both the cutaneous and the extracutaneous lesions of PCL. The available literature addressing the clinical role of F-FDG PET and PET/CT in patients with PCL is promising for the use of the modalities in staging, tumor biological evaluation, biopsy guidance, early treatment response assessment, and recurrence surveillance. However, more data are needed to better specify the role of F-FDG PET and PET/CT in the management of PCL.

    The results of treatment in 175 consecutive patients with non-Hodgkin lymphoma (NHL) clinical stage I treated between 1969 and 1984 were analysed according to different pretreatment prognostic variables. Treatment consisted of radiotherapy in 166 of the 175 patients. The estimated 5 and 10-year disease-free survival rates (DFS) were 63% and 60% and the survival rates at 5 and 10 years 82% and 76% respectively. Lymphomas arising from gut-associated lymphoid tissue, i.e. Waldeyer's ring, the thyroid and the gastrointestinal tract had a more favourable clinical course (10-year projected DFS 83%) than nodal (50%) and other extranodal lymphomas. Although the number of patients with other extranodal sites was small, sites such as testis, nasal cavity, paranasal sinus and extradural space seemed to have a high relapse rate. Unfavourable clinical courses were also observed among nodal high-grade NHL if the lymph nodes were larger than 5 cm in diameter. Chemotherapy before radiotherapy may be recommended in NHL subgroups with a high relapse rate and which today are potentially curable with chemotherapy, i.e. high-grade NHL. This study indicates that large nodal lymphomas and some extranodal sites belong to this group. (orig.)

    A case of primary malignant lymphoma of the central nervous system was reported. A 58-year-old man was admitted because of diplopia in March, 1986. Last year in June he lost consciousness, accompanied by headache, vertigo, a floating sensation, and tinnitus, though his symptoms disappeared the next day. Last year in October and November, he complained of weakness of the left hand, but it soon disappeared. A neurological examination on admission revealed left trochlear nerve palsy, a decreased sensitivity to pain on the left side of the face and the opposite side of the body, and a mild left-side lack of coordination. A head CT scan and angiography showed no abnormalities. An examination of the CSF revealed increased protein with mild pleocytosis and IgG, but cytology was negative. After admission, he complained of left trigeminal neuralgia, but it disappeared upon steroid pulse therapy. When the steroids were tapered off, however, peripheral facialnerve palsy developed. Therefore, a second course of steroid pulse therapy was done, with some effect. In June, however, the patient became unconscious while the orally administered steroid was being tapered off. A head CT scan showed isodensity masses in the basal ganglia, the thalamus, and the periventricular white matter on a plain scan, and homogeneous masses with ring enhancement and edema on the use of a contrast medium. A histopathological examination showed primary cerebral malignant lymphoma (large-cell type). (author)

    Sinus histiocytosis with massive cervical lymphadenopathy (Rosai-Dorfman disease) is a non-neoplastic lymphoproliferative disorder. Extranodal involvement, especially of the nervous system, is unusual. We report a case revealed by neurological symptoms. A 10-year-old girl presented with paraparesis due to a dural extramedullary mass on magnetic resonance imaging. Massive cervical lymphadenopathy appeared secondarily. Radiological investigations showed mediastinal, paranasal sinus and lower eyelid involvement. The diagnosis of Rosai-Dorfman disease was established histologically and by immunohistochemical studies of nodal lesions by the demonstration of characteristic sinus histiocytosis with sheets of S-100 protein and CD-68 positive large histiocytes displaying lymphocyte phagocytosis. A dramatic response occurred with complete resolution of all clinical findings after treatment with corticosteroids and etoposide, although neurological lesions were unchanged on magnetic resonance imaging. Despite its rarity, this case underlines the unknown pathogenesis of this disease (immune dysfunction?) and the difficulties of treatment (choice of chemotherapeutic agents, duration).

    2007-01-01

    Objective: To describe the general findings of lymphoma and their histological patterns in patients less than 20 years old. Materials And Methods: Twenty-two cases (16 male and 6 female, mean age 11.5 years) from the digital archive of computed tomography at the Cancer Control Center of Hospital Universitario Pedro Ernesto - Universidade do Estado do Rio de Janeiro, Rio de Janeiro, RJ, Brazil, were retrospectively analyzed in the period between March 2003 and July 2005. Of these 22 cases, 12 were Hodgkin's and 10 were non-Hodgkin's. Results: Overall, mediastinal lymphadenomegaly was the most frequent finding (59%), with predominance in the Hodgkin's subgroup (75%), followed by hepatosplenomegaly (50%) and cervical and retroperitoneal lymphadenomegaly (27.3%). The Hodgkin's subgroup presented a prevalence of lymphadenopathy, in many lymph node chains, followed by hepatosplenomegaly (50%). One case was found with unilateral tonsillar mass, pulmonary ground-glass opacities, and renal nodules. In the non-Hodgkin's subgroup, the disease was predominantly extranodal, characterized by hepatosplenomegaly (50%), thickening of the intestinal wall (40%), pleural effusion (30%), pulmonary nodule (20%), ascites (10%), pericardial effusion (10%) and mixed bone lesions (10%). Conclusion: Computed tomography is an extremely useful method for detection, staging and follow-up of lymphomas, with alert findings like mediastinal lymphadenopathy, hepatosplenomegaly, unilateral tonsillar mass and thickening of intestinal wall.

    The incorporation of rituximab in immunochemotherapy has improved treatment outcomes for diffuse large B-cell lymphoma, but the prognosis for some diffuse large B-cell lymphomas remains dismal. Identification of adverse prognostic subgroups is essential for the choice of appropriate therapeutic strategy. We retrospectively investigated the impact of so-called 'double-hit' cytogenetic abnormalities, i.e. cytogenetic abnormalities involving c-MYC co-existing with other poor prognostic cytogenetic abnormalities involving BCL2, BCL6 or BACH2, on treatment outcomes for 93 consecutive diffuse large B-cell lymphoma patients. According to the revised international prognostic index, no patients were cytogenetically diagnosed with double-hit lymphomas in the 'very good' risk group or in the 'good' risk group, while 5 of 33 patients had double-hit lymphomas in the 'poor' risk group. All the double-hit lymphoma patients possessed both nodal and extranodal involvement. The overall complete response rate was 89.3%, overall survival 87.1% and progression-free survival 75.8% over 2 years (median observation period: 644 days). The complete response rates were 93.2% for the non-double-hit lymphoma patients and 40.0% for the double-hit lymphoma patients. Significantly longer progression-free survival and overall survival were observed for the 'very good' and the 'good' risk patients than for the 'poor' risk patients. Moreover, the progression-free survival of double-hit lymphoma was significantly shorter than that of the non-double-hit lymphoma 'poor' risk patients (P = 0.016). In addition, the overall survival of the double-hit lymphoma patients also tended to be shorter than that of the non-double-hit lymphoma 'poor' risk group. The diagnosis of double-hit lymphoma can help discriminate a subgroup of highly aggressive diffuse large B-cell lymphomas and indicate the need for the development of novel therapeutic strategies for double-hit lymphoma.

    Ocular adnexal lymphomas are a group of heterogeneous neoplasms representing approximately 1-2% of non-Hodgkin lymphomas and 8% of extranodal lymphomas. The incidence of primary ocular adnexal lymphoid tumors has raised over the last decades, and this could be probably attributed to the more sophisticated diagnostic techniques. Due to the wide spectrum of clinical manifestations, ocular tissue biopsy is important in order to set a precise diagnosis based on histological, immunophenotypical and, in some cases, molecular findings. The most common subtype, which may account for up to 80% of primary ocular adnexal lymphomas, is extranodal marginal zone lymphoma (EMZL) of mucosa-associated lymphoid tissue. This lymphoma is usually asymptomatic in the early phase of the disease causing a delay in the final diagnosis and prompt therapy. The pathogenesis of a proportion of these tumors has been linked to chronic inflammatory stimulation from specific infectious factors (e.g., Chlamydia psittaci) or to autoimmunity. The further improvement in diagnostic methods and the further understanding of the pathogenesis of ocular adnexal EMZL may contribute to the establishment of a more successful multidisciplinary therapeutic planning.

    2017-01-01

    El linfoma de células T/natural killer extranodal ("extranodal natural killer/T-cell lymphoma", ENKL) nasal es un linfoma no Hodgkin (LNH) agresivo y poco común para el cual no se ha establecido un tratamiento de referencia claro, especialmente en el escenario de la enfermedad recidivante/refractaria. Debido a su rareza, no se han llevado a cabo ensayos aleatorizados específicamente en ENKL nasal; sin embargo, los informes de caso y las series de caso pequeñas ofrecen un conocimiento importante sobre nuevos tratamientos potenciales. Presentamos el informe de caso de un paciente con ENKL nasal (previamente mal diagnosticado como una sinusitis crónica recidivante) en quien la enfermedad progresó durante la quimioterapia con múltiples agentes pero respondió al tratamiento de segunda línea con pralatrexato como agente único. Analizamos opciones de tratamiento para el ENKL nasal recidivante/refractario y sugerimos que el pralatrexato se evalúe más a fondo en este escenario clínico.

    2017-05-01

    Lymphomas are classified based on the normal counterpart, or cell of origin, from which they arise. Because lymphocytes have physiologic immune functions that vary both by lineage and by stage of differentiation, the classification of lymphomas arising from these normal lymphoid populations is complex. Recent genomic data have contributed additional complexity. Areas covered: Lymphoma classification follows the World Health Organization (WHO) system, which reflects international consensus and is based on pathological, genetic, and clinical factors. A 2016 revision to the WHO classification of lymphoid neoplasms recently was reported. The present review focuses on B-cell non-Hodgkin lymphomas, the most common group of lymphomas, and summarizes recent changes most relevant to hematologists and other clinicians who care for lymphoma patients. Expert commentary: Lymphoma classification is a continually evolving field that needs to be responsive to new clinical, pathological, and molecular understanding of lymphoid neoplasia. Among the entities covered in this review, the 2016 revision of the WHO classification particularly impact the subclassification and genetic stratification of diffuse large B-cell lymphoma and high-grade B-cell lymphomas, and reflect evolving criteria and nomenclature for indolent B-cell lymphomas and lymphoproliferative disorders.

    Follicular dendritic cell sarcoma (FDCS) is a rare neoplasm of the antigen presenting cells of the immune system. The majority occur in lymph nodes but around 30% can occur extranodally including in the spleen, lungs, head and neck and liver. We present an unusual case of an FDCS of the parotid gland in a 51-year-old woman with a history of Hodgkin's lymphoma treated with combination chemotherapy and modified mantle radiotherapy. Only four cases of an intraparotid FDCS have been previously reported. The patient underwent a superficial parotidectomy and level 2/3 neck dissection. A diagnosis of an intraparotid FDCS (25 mm) with no nodal disease was made. Given this patient's history of radiotherapy 20 years previously, we speculate the possibility of postradiation sarcoma. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

    Objective: To study the clinicopathological features of primary hepatic extranodal marginal zone lymphoma of mucosa associated lymphoid tissue (MALT lymphoma) and hepatic pseudolymphoma, and to discuss their differential diagnosis, treatment and prognosis. Methods: Three primary hepatic MALT lymphomas and two hepatic pseudolymphomas collected from January 2012 to March 2017 in the First Affiliated Hospital of Nanjing Medical University were evaluated by HE and immunohistochemistry(IHC), in-situ hybridization and immunoglobulin (Ig) gene rearrangement detection, and the relevant literature reviewed. Results: In the three MALT lymphomas, tumor cells infiltrated the portal areas with nodular pattern, and invaded the surrounding normal liver with serpiginous configuration and formation of confluent sheets. A number of bile ducts were entrapped within the lesions, and showed lymphoepithelial lesion. Reactive lymphoid follicles were present and surrounded by tumor cells, consisting of predominantly centrocyte-like cells and monocytoid B cells. There were clusters of epithelioid histiocytes in one case. The tumor cells were positive for CD20, PAX5 and negative for CD5, CD23, CD10, bcl-6, and cyclin D1. In the two hepatic pseudolymphomas, the lesions presented as solitary nodules well-demarcated from the surrounding liver tissue; one case was partially encapsulated with fibrous tissue. Entrapped bile ducts were only found at the edge of the lesions without lymphoepithelial lesion. The lesions comprised of massive lymphoid proliferation consisting predominantly of reactive lymphoid follicles, but not monocytoid B-cells or atypical cells. By IHC, a mixture of B- and T-cell population was identified. A monoclonal rearrangement of the Ig gene was detected in all three MALT lymphomas but not in two pseudolymphomas. Interphase fluorescence in situ hybridiazation test for MALT1 break-apart gene was positive in two cases of MALT lymphomas and EBER was negative in all studied cases

    Diffuse large B-cell lymphoma (DLBCL) is an aggressive and potentially curable type of lymphoma. Fluorine-18-fluorodeoxyglucose positron emission tomography (FDG-PET) is part of clinical routine for DLBCL in most hospitals and also recommended for staging and end-of-therapy evaluation. FDG......-PET/computed tomography (CT) is able to identify nodal and extranodal sites with greater accuracy than CT alone. Little evidence supports the use of surveillance FDG-PET imaging in the follow-up setting because of high rates of false-positive scans and because most studies are retrospective.

    2017-08-03

    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 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.

    Primary gastric lymphomas are the most common extra nodal lymphomas. They can be presented as aggressive or indolent, majority of indolent lymphomas are associated to H. pylori infection. The basic diagnostic procedures are endoscopy, endo sonography and biopsy of gastric tissue. Therapy is related to the histological subtype, stage, H. pylori positivity, clinical symptoms and condition of patient. The aim of the treatment is remission as well as good quality of life. The prognosis of patients with primary gastric lymphomas is relatively good. (author)

    To determine whether the extent of disease in dogs with lymphoma can be assessed via flow cytometry and to evaluate the suitability of fine-needle aspirates from the liver and spleen of dogs for flow cytometric examination. 44 dogs with multicentric B-cell (n = 35) or T-cell lymphoma (9) and 5 healthy control dogs. Procedures-Peripheral blood and bone marrow samples and fine-needle aspirates of lymph node, liver, and spleen were examined via flow cytometry. Logarithmically transformed T-cell-to-B-cell percentage ratio (log[T:B]) values were calculated. Thresholds defined by use of log(T:B) values of samples from control dogs were used to determine extranodal lymphoma involvement in lymphoma-affected dogs; results were compared with cytologic findings. 12 of 245 (5%) samples (9 liver, 1 spleen, and 2 bone marrow) had insufficient cellularity for flow cytometric evaluation. Mean log(T:B) values of samples from dogs with B-cell lymphoma were significantly lower than those of samples from the same site in dogs with T-cell lymphoma and in control dogs. In dogs with T-cell lymphoma, the log(T:B) of lymph node, bone marrow, and spleen samples was significantly higher than in control dogs. Of 165 samples assessed for extranodal lymphoma involvement, 116 (70%) tested positive via flow cytometric analysis; results agreed with cytologic findings in 133 of 161 (83%) samples evaluated via both methods. Results suggested that flow cytometry may aid in detection of extranodal lymphoma involvement in dogs, but further research is needed. Most fine-needle aspirates of liver and spleen were suitable for flow cytometric evaluation.

  11. Recognizing nodal marginal zone lymphoma: recent advances and pitfalls. A systematic review

    2013-01-01

    The diagnosis of nodal marginal zone lymphoma is one of the remaining problem areas in hematopathology. Because no established positive markers exist for this lymphoma, it is frequently a diagnosis of exclusion, making distinction from other low-grade B-cell lymphomas difficult or even impossible. This systematic review summarizes and discusses the current knowledge on nodal marginal zone lymphoma, including clinical features, epidemiology and etiology, histology, and cytogenetic and molecular features. In particular, recent advances in diagnostics and pathogenesis are discussed. New immunohistochemical markers have become available that could be used as positive markers for nodal marginal zone lymphoma. These markers could be used to ensure more homogeneous study groups in future research. Also, recent gene expression studies and studies describing specific gene mutations have provided clues to the pathogenesis of nodal marginal zone lymphoma, suggesting deregulation of the nuclear factor kappa B pathway. Nevertheless, nodal marginal zone lymphoma remains an enigmatic entity, requiring further study to define its pathogenesis to allow an accurate diagnosis and tailored treatment. However, recent data indicate that it is not related to splenic or extranodal lymphoma, and that it is also not related to lymphoplasmacytic lymphoma. Thus, even though the diagnosis is not always easy, it is clearly a separate entity. PMID:23813646

    Sancho, Juan-Manuel; Ribera, Josep-Maria

    2016-01-15

    Central nervous system (CNS) involvement by lymphoma is a complication associated, almost invariably, with a poor prognosis. The knowledge of the risk factors for CNS relapse is important to determine which patients could benefit from prophylaxis. Thus, patients with very aggressive lymphomas (such as lymphoblastic lymphoma or Burkitt's lymphoma) must systematically receive CNS prophylaxis due to a high CNS relapse rate (25-30%), while in patients with indolent lymphoma (such as follicular lymphoma or marginal lymphoma) prophylaxis is unnecessary. However, the question about CNS prophylaxis in patients with diffuse large B-cell lymphoma (DLBCL), the most common type of lymphoma, remains controversial. The information available is extensive, mainly based on retrospective and heterogeneous studies. There seems that immunochemotherapy based on rituximab reduces the CNS relapse rate. On the other hand, patients with increased serum lactate dehydrogenase plus more than one extranodal involvement seem to have a higher risk of CNS relapse, but a prophylaxis strategy based only on the presence of these 2 factors does not prevent all CNS relapses. Patients with involvement of testes or breast have high risk of CNS relapse and prophylaxis is mandatory. Finally, CNS prophylaxis could be considered in patients with DLBCL and renal or epidural space involvement, as well as in those cases with MYC rearrangements, although additional studies are necessary.

    2004-07-01

    This review revisits Waldeyer's ring lymphomas as classified by the World Health Organisation. Sources of data include international studies on Waldeyer's ring lymphomas as well as from personal observations gleaned from lymphoma statistics of Singapore General Hospital, Changi General Hospital, Tan Tock Seng Hospital and National University Hospital within the last decade or so. Waldeyer's ring shares many of the histopathological trends of the rest of mucosa-associated lymphoid tissue (MALT), such as the high frequency of diffuse large B-cell lymphomas, and the relative rarity of follicular lymphomas in spite of its rich endowment with reactive lymphoid follicles. However, extranodal marginal zone lymphoma or "MALToma" may not be as frequently encountered as in other mucosal sites. Furthermore, the placement of Waldeyer's ring is unique in that stark comparisons with the lymphopathology of the immediately anterior oronasal cavities can be made, with intriguing peculiarities such as the abrupt reversal of the ratio of B-cell to T/NK-cell lymphoma frequency upon crossing the imaginary line that separates the 2 regions. The differential diagnosis with regionally common lymphoma mimics, in particular reactive parafollicular hyperplasia and nasopharyngeal undifferentiated (lymphoepithelial) carcinoma of Schmincke pattern, both often aetiologically related to Epstein-Barr viral infection, is also discussed. Recognition of the peculiarities and patterns of Waldeyer's ring lymphomas is important for accurate pathologic assessment. Postulates that attempt to account for the patterns and peculiarities of Waldeyer's ring lymphopathology can be used to direct further research.

    Sinus histiocytosis with massive lymphadenopathy (SHML), also known as Rosai-Dorfman disease, is a rare self-limiting disorder of histiocytes with unknown etiology. Sinus histiocytosis with massive lymphadenopathy is most common in children and young adults and is characterized by painless lymphadenopathy. Histologically there is a proliferation of sinus histiocytes with lymphophagocytosis or emperipolesis. On rare occasions, SHML has been associated with lymphoma, usually involving different anatomic sites and developing at different times. We report a case of concomitant SHML and nodal marginal zone lymphoma involving the same lymph node without involvement of other nodal or extranodal sites. The presence of concomitant SHML within the lymph node involved by nodal marginal zone lymphoma may represent the responsiveness of SHML histiocytes to B-cell-derived cytokines in lymphoproliferative disorders. To our knowledge, this is the first description of concomitant occurrence of SHML and nodal marginal zone lymphoma.

    Full Text Available Since nasal NK/T-cell lymphoma and NK/T-cell lymphoma nasal type are rare diseases, colonic involvement has seldom been seen. We report a case of a patient with a primary NK/T-cell lymphoma nasal type of the colon. The patient had no history of malignant diseases and was diagnosed after exhaustive study in the context of fever of unknown origin. The first therapeutic approach followed the DAEPOCH-protocol: etoposide, prednisone, doxor-rubicin, vincristine and cyclophosphamide. The persistence of constitutional symptoms after the first treatment course motivated the switch to a second line following the SMILE-protocol: dexamethasone, metotrexate, ifosfamide, E.coli L-asparaginase, and etoposide. Despite intensive chemotherapy, the patient died 2 months after the diagnose of an extranodal NK/T-cell lymphoma of the colon and 4 months after the first symptomatic appearance of disease.

    Intravascular selective growth of neoplastic B lymphocytes is a characteristic finding of intravascular large B-cell lymphoma (IVLBCL). However, because neoplastic B cells of IVLBCL grow merely in the lumina of capillaries or small vessels, primary IVLBCL of the great vessels is considered exceptional. To our knowledge, only 2 primary B-cell lymphomas in the lumina of the vena cava have been reported. However, there has been no report of primary B-cell lymphoma with intra-aortic growth. We describe a novel manifestation of primary Epstein-Barr virus-positive large B-cell lymphoma mainly affecting the lumina of the aorta and its major branches in a 76-year-old man. He had a long-term fever that was refractory to antibiotics and aortic mural thrombosis with visceral embolization. Because he had no detectable mass suggesting a malignancy, it was difficult to diagnose while he was alive. He died without anticancer treatment, and the confirmed diagnosis was made at autopsy.

    The variable natural history of mucosa-associated lymphoid tissue (MALT) lymphoma poses a challenge in predicting clinical outcome. Since Wnt signaling, as indicated by nuclear localization of beta-catenin, is believed to be key in stem cell activation and stem cell self-renewal, we explored the possibility that it might have a predictive value in marginal zone lymphoma. We chose to analyze pbeta-catenin-S552 because its nuclear localization by immunohistochemistry appears to coincide with Wnt signaling-initiated tumorigenesis in intestinal and hematopoietic tissues. Wnt signaling and activation was studied in 22 tissue samples of extranodal marginal zone lymphoma, atypical lymphoid hyperplasia, reactive lymphoid hyperplasia, and normal lymphoid tissue to determine whether Wnt signaling could help distinguish MALT lymphoma from benign lesions. Compared to normal or reactive lymphoid tissue, we found increased nuclear expression of localized pbeta-catenin-S552 in atypical lymphoid hyperplasia and extranodal marginal zone lymphoma. We show that the anti-pbeta-catenin-S552 antibody may be useful in diagnosing and monitoring the progression of or response to therapy of MALT lymphoma.

    Mucosa-associated lymphoid tissue (MALT) type lymphoma arises from extranodal marginal zone B-cell. It is etiologically associated with Helicobacter pylori infection and, hence, can be cured by antibiotic treatment. MALT type lymphoma is the most common variety of gastric lymphoma that is rare in the stomach). The published data of clinical studies on the usefulness of 18F-FDG PET in the diagnosis of MALT type lymphoma varied according to authors. Thus, the result of Hoffmann et al. was discouraging whereas a high diagnostic accuracy was reported by Ambrosini et al. The latter group further went to suggest that higher 18F-FDG uptake in gastric MALT type lymphoma would positively relate to the aggressiveness of neoplasm. The clinical studies conducted by other groups on MALT lymphomas of the stomach, lung, orbit and parotid gland and the stomach, lung, parotid gland, skin, orbit, mandible, esophagus and uterus confirmed that 18F-FDG scan is valuable

    We attempt to correlate the histological types [in three cases of B-cell non-Hodgkin's lymphoma (NHL), one case of T-cell NHL and one of Hodgkin's disease] with the radiological presentation and compare our findings with the literature reviewed. Among the mammographic studies, performed over and 18-month period, we have assessed five patients (four women and one man, aged as having lymphoma. the man presented bilateral involvement. Both mammography and a broader study with ultrasound and chest and abdominal CT scan were performed in every case. Four patients underwent breast ultrasound. The definitive diagnosis was based on biopsy in all cases. Three of the five cases involved primary lymphomas and the other two were secondary. Four patients presented NHL and the remaining patient had Hodgkin's disease. In mammography, the nodules showed different degrees of margin definition. In ultrasound, all the lesion were hypoechoic. The radiological diagnosis of breast lymphoma is difficult in the absence of a previous diagnosis of lymphoma. This lesion should be included in the differential diagnosis in the presence of a breast nodule associated with axillary lymph nodes, especially when the latter are bilateral. (Author)

    Hypercalcemia associated with haematological neoplasms account for 15 to 20% of hipercalcemia in malignancy, and occurs usually in patients with multiple myeloma. However, its incidence in patients with linfoma is low, and it is observed usually in T-cell linfomas. Bone affectation is also uncommon in patients with non-Hodgkin linfoma. It usually is seen as a late manifestation of the disease, and its occurrence as the form of presentation is exceptional. We hereby report a patient with a B-cell non-Hodgkin linfoma presenting with hypercalcemia and femoral osteolytic lesions.

  3. Molecular Aspects of H. pylori-Related MALT Lymphoma

    Directory of Open Access Journals (Sweden)

    Scott R. Owens

    2011-01-01

    Full Text Available Helicobacter pylori-related extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue is a paradigm for malignancy arising in an inflammatory background. While the diagnosis of H. pylori gastritis is often straightforward, distinction between severe gastritis and early lymphoma can be difficult and requires careful assessment of clinical findings in addition to histological features and immunohistochemical results. A number of cytogenetic abnormalities have been discovered in H. pylori-related lymphomas and several have clinical importance, related to the responsiveness of lymphoma to H. pylori eradication therapy, but routine molecular studies are not widely utilized. While molecular methods may be used in equivocal cases, a trial of conservative therapy is warranted given the propensity for these lymphomas to regress with eradication of the organism. Once therapy is initiated, care must be taken to avoid a premature assignment of disease refractoriness because complete response can take several months to more than a year. Cases truly refractory to H. pylori eradication therapy may be treated with adjuvant chemoradiation with a high response rate.

    Full Text Available The B-cell receptor signaling pathway is important in the lymphomagenesis of many lymphomas, including marginal zone lymphoma (MZL. Herein we describe a case of extranodal MZL refractory to multiple lines of therapy. The presence of an IgM paraprotein prompted further evaluation, and the patient was found to have an MYD88L265P mutation. Treatment with ibrutinib led to a dramatic response with prompt resolution of symptoms and significant improvement in measurable sites of disease. The excellent response to ibrutinib in our patient with MYD88L265P-mutated refractory MZL supports a biological rationale for its use.

    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.

    Histological transformation of follicular lymphoma (FL) to a more aggressive non-Hodgkin's lymphomas is a pivotal event in the natural history of FL and is associated with poor outcome. While commonly observed in clinical practice and despite multiple studies designed to address its pathogenesis, the biology of this process represents an enigma. In this chapter we present a state of the art review summarizing the definition of histologic transformation, its incidence, pathogenesis, clinical manifestations, treatment and outcome. Furthermore, we specifically emphasize gaps in our knowledge that should be addressed in future studies. PMID:21658615

    As in any medical disorder, in non-Hodgkin lymphomas (NHLs) also, precise analysis of causes of death is needed to focus research efforts and improve morbidity and mortality. The aim of this study was to review the clinical presentation, mode of death and the immunophenotype of the autopsy cases of NHL. Autopsy cases wherein NHL was diagnosed, were selected for study. Autopsy cases which were diagnosed as NHL, either antemortem or after autopsy during a 7 years period at a tertiary care referral centre were studied and reviewed. Descriptive statistical analysis used. The autopsy findings seen in eight cases of NHL were reviewed. Except one, all cases were above 40 years age. Infective etiology (62%) followed by cardiorespiratory failure (38%) was the cause of death observed in these patients. In three cases, the antemortem diagnosis of NHL was missed as the patients were being treated for acute febrile illness and were referred late to the Tertiary Care Centre. One of these was a case of extra-nodal primary splenic lymphoma. As NHL present with nonspecific symptoms, these tumours may not be detected in early stages and hence may not be treated appropriately. These patients have weakened immunity and hence are prone to infection and sepsis which can be a major cause of mortality. This autopsy study experience has shown that NHL can masquerade as acute febrile illness which if not detected early and treated adequately can turn fatal.

    The authors report the findings of a national survey conducted at the request for the French Society for Rheumatology to list the rheumatic manifestations that can be inaugural in Hodgkin's disease on non-Hodgkin's malignant lymphoma. This was an exploratory, retrospective, descriptive study of 146 patients from 22 rheumatology departments. A number of clinical features (young male, nocturnal sweats, generalized pruritus, protracted fever, central or peripheral lymphadenopathy) and laboratory test abnormalities (evidence of severe inflammation) considerably increased the likelihood of Hodgkin's disease rather than malignant lymphoma. The diagnosis of bony involvement requires multidisciplinary studies of tumor specimens. (authors). 4 figs., 7 tabs., 71 refs

    Objective: To describe the general findings of lymphoma and their histological patterns in patients less than 20 years old. Materials And Methods: Twenty-two cases (16 male and 6 female, mean age 11.5 years) from the digital archive of computed tomography at the Cancer Control Center of Hospital Universitario Pedro Ernesto - Universidade do Estado do Rio de Janeiro, Rio de Janeiro, RJ, Brazil, were retrospectively analyzed in the period between March 2003 and July 2005. Of these 22 cases, 12 were Hodgkin's and 10 were non-Hodgkin's. Results: Overall, mediastinal lymphadenomegaly was the most frequent finding (59%), with predominance in the Hodgkin's subgroup (75%), followed by hepatosplenomegaly (50%) and cervical and retroperitoneal lymphadenomegaly (27.3%). The Hodgkin's subgroup presented a prevalence of lymphadenopathy, in many lymph node chains, followed by hepatosplenomegaly (50%). One case was found with unilateral tonsillar mass, pulmonary ground-glass opacities, and renal nodules. In the non-Hodgkin's subgroup, the disease was predominantly extranodal, characterized by hepatosplenomegaly (50%), thickening of the intestinal wall (40%), pleural effusion (30%), pulmonary nodule (20%), ascites (10%), pericardial effusion (10%) and mixed bone lesions (10%). Conclusion: Computed tomography is an extremely useful method for detection, staging and follow-up of lymphomas, with alert findings like mediastinal lymphadenopathy, hepatosplenomegaly, unilateral tonsillar mass and thickening of intestinal wall.

    Full Text Available Intraocular lymphoma (IOL is a rare lymphocytic malignancy which contains two main distinct forms. Primary intraocular lymphoma (PIOL is mainly a sub-type of primary central nervous system lymphoma (PCNSL. Alternatively, IOL can originate from outside the central nervous system (CNS by metastasizing to the eye. These tumors are known as secondary intraocular lymphoma (SIOL. The IOL can arise in the retina, uvea, vitreous, Bruch’s membrane and optic nerve. There are predominantly of B-cell origin; however there are also rare T-cell variants. Diagnosis remains challenging for ophthalmologists and pathologists, due to its ability to masquerade as noninfectious or infectious uveitis, white dot syndromes, or occasionally as other metastatic cancers. Laboratory tests include flow cytometry, immunocytochemistry, interleukin detection (IL-10: IL-6, ratio >1, and polymerase chain reaction (PCR amplification. Methotrexate-based systemic chemotherapy with external beam radiotherapy and intravitreal chemotherapy with methotrexate are useful for controlling the disease, but the prognosis remains poor. Therefore, it is important to make an early diagnose and treatment. This review is focused on the clinical manifestations, diagnosis, treatment and prognosis of the IOL.

    2014-01-01

    Fluoro-deoxyglucose positron emission tomography combined with computed tomography (FDG-PET/CT) is superior to iliac bone marrow biopsy (iBMB) for detection of bone marrow involvement (BMI) in staging of Hodgkin's lymphoma (HL). The present study aims to characterize the patterns and distribution of BMI in HL as determined by FDG-PET/CT. Reports of FDG-PET/CT studies performed for staging of HL were reviewed. BMI was defined as positive iBMB and/or foci of pathological FDG uptake in the skeleton that behaved in concordance with other sites of lymphoma in studies following chemotherapy. Number of FDG uptake foci, their specific location in the skeleton and the presence of corresponding lesions in the CT component of the study, and stage according to the Ann Arbor staging system, were recorded. The study included 473 patients. iBMB was performed in 336 patients. Nine patients had positive iBMB (9/336, 3 %). Seventy-three patients (73/473, 15 %) had FDG-PET/CT-defined BMI. The BM was the only extranodal site of HL in 52/473 patients (11 %). Forty-five patients had three or more foci of pathological skeletal FDG uptake (45/73, 62 %). Sixty-four patients (64/73, 88 %) had at least one uptake focus in the pelvis or vertebrae. In 60 patients (60/73, 82 %), the number of skeletal FDG uptake foci without corresponding CT lesions was equal to or higher than the number of foci with morphological abnormalities. FDG-PET/CT demonstrated BMI in 15 % of patients with newly diagnosed HL. Diagnosis of BMI in HL by FDG-PET/CT was more sensitive than iBMB with potential upstage in 11 % of patients. The most common pattern of FDG-PET/CT BMI was multifocal (at least three foci) skeletal FDG uptake, with at least one focus in the pelvis or vertebrae and no corresponding CT lesions. (orig.)

    Mendez, Miriam; Torrente, Maria; Provencio, Mariano

    2017-06-01

    Follicular lymphoma (FL) is the second most common type of non-Hodgkin lymphoma (NHL). Histological transformation (HT) refers to the evolution of a clinically indolent NHL to a clinically aggressive one, defined as those lymphomas in which survival is limited to a few months when untreated. Areas covered: HT is associated with rapid progression of lymphadenopathy, infiltration of extranodal sites, development of systemic symptoms, and elevated serum level of lactate dehydrogenase (LDH). It is frequently related to a poor prognosis, and the median survival after transformation is less than 2 years. Transformation to diffuse large B cell lymphoma (DLBCL) in patients with FL occurs at an annual rate of approximately 3% for the first 15 years, after which the risk of HT falls for reasons that remain unclear. Expert commentary: Although it has long been assumed that transformation reflects the emergence of an aggressive subclone of cells from the primary FL, recent studies suggest that FL transformation might also arise by divergent evolution from a more immature common progenitor cell. Studies on genomic changes and DNA sequencing have shed some light onto the process of transformation. Nowadays, we know that HT is a complex process where several molecular pathways are involved.

Giovanni e Paolo, Venice, Italy Abstract: About one-half of all Burkitt lymphoma (BL patients are younger than 40 years, and one-third belong to the adolescent and young adult (AYA subset, defined by an age between 15 and 25–40 years, based on selection criteria used in different reports. BL is an aggressive B-cell neoplasm displaying highly characteristic clinico-diagnostic features, the biologic hallmark of which is a translocation involving immunoglobulin and c-MYC genes. It presents as sporadic, endemic, or epidemic disease. Endemicity is pathogenetically linked to an imbalance of the immune system which occurs in African children infected by malaria parasites and Epstein–Barr virus, while the epidemic form strictly follows the pattern of infection by HIV. BL shows propensity to extranodal involvement of abdominal organs, bone marrow, and central nervous system, and can cause severe metabolic and renal impairment. Nevertheless, BL is highly responsive to specifically designed short-intensive, rotational multiagent chemotherapy programs, empowered by the anti-CD20 monoclonal antibody rituximab. When carefully applied with appropriate supportive measures, these modern programs achieve a cure rate of approximately 90% in the average AYA patient, irrespective of clinical stage, which is the best result achievable in any aggressive lymphoid malignancy to date. The challenges ahead concern the following: optimization of management in underdeveloped countries, with reduction of diagnostic and referral-for-care intervals, and the applicability of currently curative regimens; the development of lower intensity but equally effective treatments for frail or

    Full Text Available Non-Hodgkin's lymphomas are extremely rare among all tumors of female reproductive system. Diagnostic mistakes and inadequate therapeu- tic tactics in these diseases are results of usual absence of alertness of gynecologists. The aims are to analyze reasons of diagnostic mistakes in patients with non-Hodgkin's lymphomas of female reproductive system and to discover definitive clinical and morphological characteristics of female reproductive system lymphoid tumors. During the period between 1989 and 2006, 305 cases of primary extranodal non-Hodgkin's lym- phomas were detected; female reproductive system was affected in 7% of patients (totally 40 patients, which were included in investigated group. In the whole analyzed group of women (n=40, median age 43 yrs, range 17-84 yrs, patients with primary lesion of female reproductive system had median age of 40 yrs and with secondary involvement - 46 yrs. Most of patients were fertile (60%, n=24. Such tumors was localized in breast in 40% of cases (n=16, in ovaries - 20% (n=8, in uterine corpus - 12,5% (n=5, in uterine cervix - 15% (n=6, and in vagina - remaining 12,5% (n=5. Average time from diagnosis to beginning of the treatment was 7,5 months. As a result, the onset of specific therapy was delayed in 65% cases (n=26 and 50% (n=20 underwent unneeded surgery. Diagnostic mistakes lead to inadequate treatment. Extranodal non-Hodgkin’s lymphomas of female reproductive system, both primary and secondary, are rare pathology. Primary lesion is more typical for older women, sec- ondary is mainly affecting younger women (in reproductive period. Chemotherapy response and prognosis are better in primary cases.

    A 51-year-old female who presented with obstructive jaundice was found to have masses in the pancreatic head and tail as well as suspicious liver and periaortic masses on imaging. Aspiration cytology of the pancreatic tail mass showed abundant large single cells with vacuolated eosinophilic cytoplasm, marked nuclear pleomorphism, large bizarre irregular nuclei, binucleation, and prominent nucleoli. Numerous cells also showed intracytoplasmic black to brown pigmentation. A cell block was obtained and extensive immunohistochemical staining was performed. S-100, HMB-45, Sox10, pancytokeratin, CK7, RCC antigen, synaptophysin, HepPar 1, inhibin, CD45, CD21, and CD123 were negative, making melanoma, epithelial malignancies, lymphoma, follicular dendritic and plasmacytoid dendritic cell neoplasms less likely. CD4 and CD56 showed partial positivity, and CD68, CD163, and CD14 were positive, supporting the diagnosis of histiocytic sarcoma. Surgical specimens and immunohistochemistry confirmed the cytologic findings. Histiocytic sarcoma is a rare aggressive malignancy of histiocytic origin with most cases presenting in adults in extranodal sites, most commonly the intestinal tract. Few cases are reported in the literature, presenting diagnostic challenges for cytopathologists when seen on fine-needle aspiration. We present the first reported case of histiocytic sarcoma presenting as a pancreatic mass, diagnosed by endoscopic ultrasound guided fine-needle aspiration (EUS-FNA). This entity is rarely described on cytology and arose in a location in which EUS-FNA is the diagnostic modality of choice. This case study highlights that cytopathologists should be aware of histiocytic sarcoma occurring in extranodal locations accessible by EUS-FNA and be familiar with the cytomorphologic appearance. © 2017 Wiley Periodicals, Inc.

    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.

    2009-06-01

    Full Text Available BACKGROUND: 2-[18F]-Fluoro-2-Deoxy-D-Glucose (FDG-PET is a well established functional imaging modality for the initial staging of Hodgkin lymphoma (HL in patients from Western Europe and North America. The reliability of FDG-PET in populations of different ethnic groups is unclear, as all investigations published to date have come from developed countries. PURPOSE: The aim of the present study was to investigate the effectiveness of FDG-PET in the initial staging of HL patients in a Brazilian population. METHODS: Eighty-two patients with newly diagnosed HL were prospectively included in the study. All patients were staged with both conventional clinical staging (CCS methods, including computed tomography (CT and whole-body FDG-PET methods. A standard of reference for the nodal regions and the extranodal organs was determined using all available information, including the CCS methods, FDG-PET, the diagnostic histology and the follow-up examinations. The results of the CCS were then compared to the FDG-PET results. RESULTS: The sensitivity of FDG-PET was higher for nodal staging than that of CT (87.8% vs. 61.6%, respectively. FDG-PET was also more sensitive than CT in regard to evaluating the extranodal organs for lymphomatous involvement (96.2% vs. 40.0%, respectively. FDG-PET detected all 16 patients who were characterized by a positive bone marrow biopsy and identified an additional 4 patients with bone marrow disease. The incorporation of FDG-PET coupled with CCS in the staging procedure upstaged 20% (17/82 of the patients and downstaged 11% (9/82 of the patients. As a result of these changes in staging, 15% (13/82 of the patients would have received a different therapeutic regimen. CONCLUSIONS: The FDG-PET method is superior to CT for the detection of nodal and extra-nodal HL. The observation that the FDG-PET method upstaged the disease was the most common result (20% of patients brought about by the addition of PET to the staging algorithm

    Full Text Available Lymphomas occur with an increased frequency in patients with Human Immunodeficiency Virus (HIV infection. These are usually high-grade immunoblastic lymphomas and primary central nervous system lymphomas. Anaplastic large cell lymphoma (ALCL is a distinct type of non-Hodgkin′s lymphoma. It is uncommon in HIV infected individuals. We describe here an uncommon presentation of this relatively rare lymphoma in the form of spinal cord compression syndrome in a young HIV infected individual.

    We describe a primary periosteal lymphoma that involved only the periosteum without affecting the adjacent medulla or the regional lymph nodes. No other lymphomatous foci were found in either the distant lymph nodes or viscera. This unusual presentation simulates the imaging appearance of surface lesions of bone, namely benign and malignant tumors, and departs from the typical appearance of primary lymphoma of bone. Therefore, this rare type of lymphoma should be considered in the differential diagnosis of surface bone lesions. (orig.)

    Follicular lymphoma (FL) is an indolent lymphoma that transforms to high-grade lymphoma, mostly diffuse large B-cell lymphoma, in about a third of patients. We present the first report of a case of FL that transformed to plasmablastic lymphoma (PBL). Clonal transformation of the FL to PBL was evidenced by identical IGH/BCL2 gene rearrangements and VDJ gene usage in rearranged IGH genes. IGH/ BCL2 translocation was retained in the PBL, which also acquired c-myc gene rearrangement. Genealogic analysis based on somatic hypermutation of the rearranged IGH genes of both FL and PBL suggests that transformation of the FL to PBL occurred most likely by divergent evolution from a common progenitor cell rather than direct evolution from the FL clone. Our study of this unusual case expands the histologic spectrum of FL transformation and increases our understanding of the pathogenetic mechanisms of transformation of indolent lymphomas to aggressive lymphomas.

    To investigate the relationship between extranodal tumor deposits and prognosis in patients with colorectal cancer. The literatures on extranodal tumor deposits and postoperative survival rate in patients with colorectal cancer published at home and abroad from 1990 to 2014 were retrieved in 15 English literature databases such as MEDLINE/PubMed, Web of Science, Directory of Open Access Journals(DOAJ), SpringerLink and Chinese literature databases such as Chinese Biomedical Literature Database CD-ROM, China National Knowledge Infrastructure (CNKI) Database with the internet platform of Yonsei University Library. After screening for inclusion, data extraction and quality assessment, meta-analysis was conducted by the Review Manager 5.3 software. There were 10 studies meeting the inclusion criteria for meta-analysis. The total sample size of the studies was 4 068 cases with ENTD(+) 727 cases, while ENTD(-) 3 341 cases. Meta analysis showed that 5-year overall survival rate and 5-year relapse-free survival rate were significantly lower in ENTD(+) group than those in ENTD(-) group (OR 0.27, 0.23; 95% CI:0.18 to 0.43, 0.16 to 0.34 respectively, both P=0.000); the 5-year overall survival rates were both significantly lower in ENTD(+) group as compared to ENTD(-) group for patients with N0 and N(+) colorectal cancer (both P<0.05). Extranodal tumor deposits is a poor prognostic factor of patients with colorectal cancer.

    2004-01-01

    Purpose: As scarce information is available, in this research we have tried to describe the imaging findings of the Burkitt's lymphoma. Retrospective analysis of the clinical and imaging presentation of a 4 years old boy, is given. Biopsy confirmed the BL. Different imaging techniques were combined. The X-rays were negative. The US revealed a moderate hepatomegaly with multiple hypoechoic nodules and free fluid in the abdominal cavity. The CT showed the hepatomegaly as well as solid nodules in great number and different sizes(due to the densitometric behaviour and to post contrast enhancement), a scarce amount of ascites and a density increase of the mesentery fat. The MRI characterized and revealed in detail the US and the CT findings. The Burkitt's lymphoma is a rare entity; several methods are needed to approach the diagnosis. It represents a great clinical and imaging challenge. (author)

    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.

    Objective was to present a histopathologic and immunohistochemical analysis of primary gastric lymphomas that was reclassified according to the new World Health Organization classification of lymphoid neoplasms. We reviewed the morphological and immunohistochemical features of 28 patients with gastric lymphomas, diagnosed in the Department of pathology at the University Hospital of Tishreen University, Lattakia, Syria, during the period 1994-2003. Specimens were obtained from endoscopic and surgical biopsies. The immunohistochemical study was performed to analyze the immunophenotype of these lymphomas. Patients were aged 17-71 years. There was a slight predominance of females (male to female ratio, 13:15). Seventeen of the patients had tumors mainly located in the gastric antrum. Histologically, the most common lymphoma was of mucosa-associated lymphoid tissue (MALT) type (20 patients), also with diffuse large B-cell lymphoma (7 patients) and anaplastic large cell lymphoma (one patient). Our study demonstrates the different patterns of gastric lymphomas in Lattakia, Syria during a 10-year period in 28 Syrian patients, and reveals that the most primary gastric lymphomas are B-cell MALT lymphomas.

    Extranodal natural killer/T-cell lymphoma, nasal type (NKTL) is a rare but highly aggressive Epstein-Barr virus-related malignancy, which mainly occurs in nasopharyngeal and nasal/paranasal areas. In addition to its high prevalence in Asian, Central American and South American populations, its incidence rate has been gradually increasing in Western countries. The current mainstay of treatment is a combination of multiple chemotherapies and irradiation. Although chemoradiotherapy can cure NKTL, it often causes severe and fatal adverse events. Because a growing body of evidence suggests that immunotherapy is effective against hematological malignancies, this treatment could provide an alternative to chemoradiotherapy for treatment of NKTL. In this review, we focus on how recent findings could be used to develop efficient immunotherapies against NKTL.

    Purpose: To review our institutional experience with primary orbital lymphoma and determine the prognostic factors for survival, local control, and distant metastases. In addition, we also analyzed the risk factors for complications in the radiotherapeutic management of this tumor. Methods and Materials: Between 1973 and 1998, 47 patients (29 women [62%] and 18 men [38%], median age 69 years, range 32-89) with Stage IAE orbital lymphoma were treated with curative intent at one department. Five had bilateral orbital involvement. The tumor was located in the eyelid and extraocular muscles in 23 (44%), conjunctiva in 17 (33%), and lacrimal apparatus in 12 (23%). The histologic features according to the World Heath Organization classification of lymphoid neoplasms was follicular lymphoma in 25, extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue type in 8, diffuse large B-cell lymphoma in 12, mantle cell lymphoma in 6, and peripheral T-cell lymphoma in 1. For the purposes of comparison with the existing literature on orbital lymphomas, the grading system according to the Working Formulation was also recorded. The histologic grade was low in 33 (63%), intermediate in 18 (35%), and high in 1 (2%). All patients were treated with primary radiotherapy alone. The median dose for low-grade tumors was 3000 cGy (range 2000-4020); the median dose for intermediate and high-grade tumors was 4000 cGy (range 3000-5100). A lens-sparing approach was used in 19 patients (37%). Late complications for the lens and cornea were scored according to the subjective, objective, management, and analytic (SOMA) scale of the Late Effects of Normal Tissue (LENT) scoring system. The median follow-up was 55 months (range 6-232). Results: The local control rate was 100% in the 52 orbits treated. The 5-year overall survival and relapse-free survival rate was 73.6% and 65.5%, respectively. Tumor grade and location did not predict for overall survival or relapse-free survival

    Full Text Available Primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL-LT is one of the well-recognized extranodal lymphomas commonly addicted to the B-cell receptor-MYD88 superpathway. We aimed to describe the genomic changes in a patient who progressed through treatment with ibrutinib, a Bruton’s tyrosine kinase (BTK inhibitor. An 80-year-old woman presented with multiply relapsed PCDLBCL-LT after multiple lines of chemoimmunotherapy and radiotherapy. Pre-treatment testing of the localized cutaneous tumor lesion on a lymphoid amplicon panel demonstrated an MYD88 p.L265P mutation. Ibrutinib therapy was subsequently commenced, resulting in complete resolution of the skin disease. Despite an ongoing skin response, the patient developed progressive nodal disease at two months. Genomic analysis of the cutaneous tumor sample at baseline was compared to that of the inguinal lymph node upon progression, and revealed the acquisition of multiple genomic changes. These included several aberrations expected to bypass BTK inhibition, including two CARD11-activating mutations, and a deleterious mutation in the nuclear factor kappa B (NF-κB negative regulator, NFKBIE. In addition, an IgH-IRF8 translocation was detected (which brings the IRF8 transcription factor under control of the immunoglobulin heavy chain locus, representing a third plausible mechanism contributing to ibrutinib resistance. Several copy-number changes occurred in both samples, including an amplification of 18q, which encodes the anti-apoptotic protein BCL2. We describe the first case of novel genomic changes of PCDLBCL-LT that occurred while on ibrutinib, providing important mechanistic insights into both pathogenesis and drug resistance.

    In children with Hodgkin's disease and non-Hodgkin's lymphoma, the ability of 18 F-fluoro-2-deoxy-D-glucose PET/CT and conventional imaging (CI) to detect malignant lesions and predict poor lesion response to therapy was assessed and compared. A retrospective review of findings reported on PET/CT and CI was performed using a lesion-based analysis of 16 lymph node and 8 extra-nodal regions. Lesions were defined by histopathological findings or follow-up > 6 months. The study included 209 PET/CT scans with a valid CI comparator. A total of 5,014 regions (3,342 lymph node, 1,672 extra-nodal) were analysed. PET/CT performed significantly better than CI in the detection of malignant lesions with sensitivity and specificity of 95.9 and 99.7% compared to 70.1 and 99.0%, respectively. For predicting poor lesion response to therapy, PET/CT had fewer false-positive lesions than CI. The specificity for predicting poor lesion response to treatment for PET/CT was 99.2% compared to 96.9% for CI. PET/CT was the correct modality in 86% of lesions with discordant findings. PET/CT is more accurate than CI in detecting malignant lesions in childhood lymphoma and in predicting poor lesion response to treatment. In lesions with discordant findings, PET/CT results are more likely to be correct. (orig.)

    Neoplastic cells from 253 patients with leukemia and 46 patients with malignant lymphoma were studied for the presence of terminal deoxynucleotidyl transferase (TdT) by biochemical and fluorescent antibody technics. TdT was detected in circulating blast cells from 73 of 77 patients with acute lymphoblastic leukemia, 24 of 72 patients with chronic myelogenous leukemia examined during the blastic phase of the disorder and in cell suspensions of lymph nodes from nine of nine patients with diffuse lymphoblastic lymphoma. Blast cells from six of 10 patients with acute undifferentiated leukemia were TdT positive, but the enzyme was found in only two of 55 patients with acute myeloblastic leukemia. TdT was not detected in other lymphocytic or granulocytic leukemias or in other types of malignant lymphomas. The fluorescent antibody assay for TdT permits rapid and specific identification of the enzyme in single cells. The TdT assay is clinically useful in confirming the diagnosis of acute lymphoblastic leukemia, evaluating patients with blastic chronic myelogenous leukemia, and distinguishing patients with lymphoblastic lymphoma, whose natural history includes rapid extranodal dissemination, from patients with other poorly differentiated malignant lymphomas.

    Full Text Available In the present edition of Significação – Scientific Journal for Audiovisual Culture and in the others to follow something new is brought: the presence of thematic dossiers which are to be organized by invited scholars. The appointed subject for the very first one of them was Radio and the invited scholar, Eduardo Vicente, professor at the Graduate Course in Audiovisual and at the Postgraduate Program in Audiovisual Media and Processes of the School of Communication and Arts of the University of São Paulo (ECA-USP. Entitled Radio Beyond Borders the dossier gathers six articles and the intention of reuniting works on the perspectives of usage of such media as much as on the new possibilities of aesthetical experimenting being build up for it, especially considering the new digital technologies and technological convergences. It also intends to present works with original theoretical approach and original reflections able to reset the way we look at what is today already a centennial media. Having broadened the meaning of “beyond borders”, four foreign authors were invited to join the dossier. This is the first time they are being published in this country and so, in all cases, the articles where either written or translated into Portuguese.The dossier begins with “Radio is dead…Long live to the sound”, which is the transcription of a thought provoking lecture given by Armand Balsebre (Autonomous University of Barcelona – one of the most influential authors in the world on the Radio study field. It addresses the challenges such media is to face so that it can become “a new sound media, in the context of a new soundscape or sound-sphere, for the new listeners”. Andrew Dubber (Birmingham City University regarding the challenges posed by a Digital Era argues for a theoretical approach in radio studies which can consider a Media Ecology. The author understands the form and discourse of radio as a negotiation of affordances and

    Full Text Available Presence of lymph node (LN metastasis is a strong prognostic factor in breast cancer, whereas the importance of extra-nodal extension and other nodal tumor features have not yet been fully recognized. Here, we examined microscopic features of lymph node metastases and their prognostic value in a population-based cohort of node positive breast cancer (n = 218, as part of the prospective Norwegian Breast Cancer Screening Program NBCSP (1996-2009. Sections were reviewed for the largest metastatic tumor diameter (TD-MET, nodal afferent and efferent vascular invasion (AVI and EVI, extra-nodal extension (ENE, number of ENE foci, as well as circumferential (CD-ENE and perpendicular (PD-ENE diameter of extra-nodal growth. Number of positive lymph nodes, EVI, and PD-ENE were significantly increased with larger primary tumor (PT diameter. Univariate survival analysis showed that several features of nodal metastases were associated with disease-free (DFS or breast cancer specific survival (BCSS. Multivariate analysis demonstrated an independent prognostic value of PD-ENE (with 3 mm as cut-off value in predicting DFS and BCSS, along with number of positive nodes and histologic grade of the primary tumor (for DFS: P = 0.01, P = 0.02, P = 0.01, respectively; for BCSS: P = 0.02, P = 0.008, P = 0.02, respectively. To conclude, the extent of ENE by its perpendicular diameter was independently prognostic and should be considered in line with nodal tumor burden in treatment decisions of node positive breast cancer.

    While the International Prognostic Index is commonly used to predict outcomes in immunocompetent patients with aggressive B-cell non-Hodgkin lymphomas, HIV-infection is an important competing risk for death in patients with AIDS-related lymphomas. We investigated whether a newly created prognostic score (AIDS-related lymphoma International Prognostic Index) could better assess risk of death in patients with AIDS-related lymphomas. We randomly divided a dataset of 487 patients newly diagnosed with AIDS-related lymphomas and treated with rituximab-containing chemoimmunotherapy into a training (n=244) and validation (n=243) set. We examined the association of HIV-related and other known risk factors with overall survival in both sets independently. We defined a new score (AIDS-related lymphoma International Prognostic Index) by assigning weights to each significant predictor [age-adjusted International Prognostic Index, extranodal sites, HIV-score (composed of CD4 count, viral load, and prior history of AIDS)] with three risk categories similar to the age-adjusted International Prognostic Index (low, intermediate and high risk). We compared the prognostic value for overall survival between AIDS-related lymphoma International Prognostic Index and age-adjusted International Prognostic Index in the validation set and found that the AIDS-related lymphoma International Prognostic Index performed significantly better in predicting risk of death than the age-adjusted International Prognostic Index (P=0.004) and better discriminated risk of death between each risk category (P=0.015 vs. P=0.13). Twenty-eight percent of patients were defined as low risk by the ARL-IPI and had an estimated 5-year overall survival (OS) of 78% (52% intermediate risk, 5-year OS 60%; 20% high risk, 5-year OS 50%).

    To diagnose and classify the various entities of lymphomas, the World Health Organisation (WHO) classification is applied in human as well as in veterinary medicine. We validated the concordance of these classification systems by having a veterinary and human pathologist evaluate gastrointestinal lymphoma tissue from 61 cats. In 59% of all cases, there was a match between their respective diagnoses of the lymphoma subtype. A complete consensus between the two evaluators was obtained for all samples with a diagnosis of diffuse large B-cell lymphoma, T-cell anaplastic large cell lymphoma and extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue. A corresponding diagnosis was also made in the majority of samples with enteropathy associated T-cell lymphoma (EATL) type II, although this subtype in cats has similarities to the 'indolent T-cell lymphoproliferative disorder of the gastrointestinal tract', a provisional entity newly added to the revised human WHO classification in 2016. Very little consensus has been found with cases of EATL type I due to the fact that most did not meet all of the criteria of human EATL I. Hence, the human pathologist assigned them to the heterogeneous group of peripheral T-cell lymphomas (not otherwise specified). Consequently, concrete guidelines and advanced immunophenotyping based on the model of human medicine are essential to differentiate these challenging entities in veterinary medicine.

    Peripheral T- or natural killer (NK)-cell lymphomas are rare and difficult-to-recognize diseases. It remains arduous to distinguish between NK cell- and cytotoxic T-lymphocyte-derived lymphomas through routine histological evaluation. To clarify the cells of origin, we focused on NK-cell receptors and examined the expression using immunohistochemistry in 22 cases with T- and NK-cell neoplasms comprising angioimmunoblastic T-cell lymphoma, anaplastic lymphoma kinase (ALK)-positive and -negative anaplastic large-cell lymphomas, extranodal NK/T-cell lymphoma, nasal type, monomorphic epitheliotropic intestinal T-cell lymphoma, aggressive NK-cell leukemia, and other peripheral T-cell lymphomas. Inhibitory receptor leukocyte immunoglobulin-like receptor subfamily B member 1 (LILRB1) was detected in 14 (64%) cases, whereas activating receptors DNAM1, NKp46, and NKG2D were expressed in 7 (32%), 9 (41%), and 5 (23%) cases, respectively. Although LILRB1 was detected regardless of the disease entity, the activating NK-cell receptors were expressed predominantly in TIA-1-positive neoplasms (DNAM1, 49%; NKp46, 69%; and NKG2D, 38%). In addition, NKp46 and NKG2D were detected only in NK-cell neoplasms and cytotoxic T-lymphocyte-derived lymphomas including monomorphic epitheliotropic intestinal T-cell lymphoma. One Epstein-Barr virus-harboring cytotoxic T-lymphocyte-derived lymphoma mimicking extranodal NK/T-cell lymphoma, nasal type lacked these NK-cell receptors, indicating different cell origin from NK and innate-like T cells. Furthermore, NKG2D expression showed a negative impact on survival among the 22 examined cases, which mainly received the standard chemotherapy regimen (log-rank test, P = .024). We propose that the presence of activating NK-cell receptors may provide new insights into understanding peripheral T-cell lymphomas and characterizing them as innate-like T-cell neoplasm. © 2018 The Authors.

    The epidemic of acquired immunodeficiency syndrome (AIDS) increased the incidence of lymphoma, particularly the non-Hodgkin's lymphoma. The lymphoma in immune deficient patients is usually high-grade, very aggressive and with poor prognostic. We report the radiologic characteristics of AIDS-related lymphoma in 19 patients and correlate with the literature. The disease was predominant in homosexual male patients, with mean age of 38 years. The radiological characteristics are nonspecific to differential diagnosis, but we must suspect of lymphoma. We found ring-enhanced lesions in the radiologic studies of central nervous system. Hylar and mediastinal lymphadenopath, nodules and alveolar infiltration were detected on thoracic examinations. Abdominal examinations showed hepatosplenomegaly, lymphadenopathy, hepatic focal lesions and thickneded with distorted mucosa in the alimentary tract. Bone involvement presented as focal and disseminated destructive lesions. (author)

    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.)

    Full Text Available Background and objective: Primary brain lymphoma is an extranodal aggressive intracranial neoplasm of lymphocytic origin originating and confined to the brain parenchyma and meninges. It is rare in immune competent patients, but its incidence is increasing. This retrospective study was conducted to record the MRI features of primary brain lymphoma at the time of diagnosis in immunocompetent patients. Methods: Of the 450 patients diagnosed with the brain tumor during a period of five years from 2008 to 2013, the clinical features and MRI findings of 16 cases of pathologically proven to be non-Hodgkin’s lymphoma were studied. All the patients were tested negative for HIV and there was no history of immune suppression drugs or any other chronic illness. All the patients were examined with MRI observing the tumor location, multifocality, signal intensity in different sequences, enhancement patterns, peritumoral edema, the presence of hemorrhage and calcification. Results: Of the 16 patients, including the monofocal and multifocal cases, 30 lesions exhibited. The mean age at diagnosis was 53 years. Nine patients (56.25% found to have a multifocal disease. In more than 75% of lesions, MRI was hypo to iso signal on T1 and T2. Mild to moderate perilesional edema, strong contrast enhancement and restricted diffusion were seen in all cases. The hemorrhagic tumor was noticed in four lesions (13.3%. No calcification and no leptomeningeal lesions were noted. The MRI images in post steroid therapy were studied within one month of treatment. Tumour regression was noticed in 21/30 (70%, stable in 3/30 (10% and progressing in 6/30 (20%. Conclusion: MRI is a reliable imaging technique in the management of patients with primary brain lymphoma. Early accurate diagnosis is crucial to avoid the unnecessary operation and shift patients from extensive surgery to chemoradiotherapy.

    The lymphomas type MALT or the mucosa-associated lymphoid tissue, are the most recent variety of non-Hodgkin lymphomas present mainly in the gastric mucosa associated with Helycobacter pylori infection and in the thyroid gland in relation to Hashimoto's thyroiditis. Frequently the origin of this lesion can't be determined only by cytology study, thus it is necessary the histopathology analysis for a definitive diagnosis in most cases. Present paper includes the case of male patient with bilateral volume increase of both parotid glands and a diagnosis cytopathological of a benign lymphoepithelial process and the development of a type MALT lymphoma in relation to the right parotid gland.

    Full Text Available Abstract Background Pure akinesia (PA is a distinct form of parkinsonism characterized by freezing phenomena. Little is known about brain tumor-associated PA. We highlight the clinicoradiological changes in a patient with PA and central nervous system (CNS metastases of natural killer/T-cell lymphoma (NKTL. Case presentation A 68-year-old man with stage IVB extranodal NKTL developed a gait disturbance. Neurological examination of his gait revealed freezing, start hesitation, short step, forward flexion posture, festination and postural instability. Mild facial hypomimia and micrographia were observed. There was no rigidity or tremor in any of the four extremities. Brain magnetic resonance imaging (MRI displayed T2-hyperintense lesions in the dorsal brainstem, cerebellum and periventricular white matter. Diffusion-weighted imaging (DWI and the apparent diffusion coefficient (ADC revealed hyperintensity in these regions. Cerebrospinal fluid cytology revealed CD56-positive cells on immunohistochemical staining. The patient's neurological deficits did not respond to L-dopa treatment and intrathecal administration of methotrexate (MTX. Two weeks later, he displayed confusion and generalized convulsions. T2-hyperintense lesions spread to the basal ganglia and the infratentorial regions. Gadolinium enhancement was observed in the cerebellum and frontal subcortex. DWI and the ADC revealed diffusion-restricted lesions in the middle cerebellar peduncles, left internal capsules and cerebral white matter. MTX pulse therapy and intrathecal administration of cytosine arabinoside and MTX were performed. Two months later, his ambulatory state was normalized. Brain MRI also revealed marked alleviation of the infratentorial and supratentorial lesions. Conclusions The clinicoradiological profile of our patient suggested that dorsal ponto-mesencephalic lesions could contribute to the pathogenesis of PA. Physicians should pay more attention to striking CNS seeding

    Full Text Available Cytotoxic lymphomas comprise a spectrum of peripheral T-cell lymphomas that can have a initial or late cutaneous presentation. We describe a 46-year-old man from Cape Verde, with a dermatosis involving his face and trunk, consisting of monomorphic papules with a smooth surface and both motor and sensory polyneuropathy.The hypothesis of leprosy was supported by the clinical and initial hystopathological findings and the patient was referred to our hospital with suspected Hansen's disease. In the new skin and lymph node biopsies a lymphocyte population was identified whose immunohystochemistry study allowed the diagnosis of T-cell lymphoma with expression of cytotoxic markers. The patient was started on chemotherapy with initial remission of the skin lesions but, subsequently, progression of systemic disease.Os linfomas citotóxicos compreendem um espectro de linfomas de células T periféricos e linfomas Natural Killer que podem ter expressão cutânea primária ou secundária.

    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.

    Tuberculosis and lymphoma, these 2 dieases can present with lymphadenopathy in anywhere of the body. Therefore differentiation of tuberculosis from lymphoma is often difficult. CT scans of 17 patients with tuberculosis and 23 patients with lymphoma were retrospectively reviewed to evaluate the efficacy of CT scans in differentating adenopathy between tuberculosis and lymphoma. All the patients underwent abdominal CT scans with contrast enhancement before treatment. The size, internal architecture, distribution of lymph nodes, and associated findings on CT scans were analyzed. As compared with lymphoma, tuberculous lymphadenopathy showed 1) female preponderance (65%), 2) predilection for percolative lymph nodes (47%), 3) internal low attenuation in lymph nodes (82%), 4) cold abscess formation (24%). Characteristics of lymphoma on CT scans include 1) male preponderance (78%), 2) conglomeration of lymph nodes (39%), 3) homogeneous internal lymph node structure (83%). These results suggest that evaluation of the cahracteristics of lymphadenopathy on CT scans is helpful for differentiating between tuberculousis and lymphoma

    Lymphoma (Hodgkin's and non-Hodgkin's) is a disease of the lymphatic system where the central neural system is affected in very rare cases. According to different authors the frequency of cases with lymphoma where the neural system is affected varies between 0, 2 % and 0, 5 %, and the primary cerebral lymphoma accounts for about 1-2% of ail brain neoplasms. The intracranial form of iymphoma is usually a late onset of the disease with serious and potentially fatal complications for the patient. These complications usually appear several years after diagnosing the disease, but the cerebral lymphoma may occur even in patients who are in remission which is the case with our patient. We present you a case with a 38 -year-old female, who was hospitalized in the Neuro ward with the following complaints -loss of speech for a few minutes, dizziness, weakness, tingling in her right leg as well as shuffling. This patient was diagnosed with histological B-cell non-Hodgkin's lymphoma 8 years ago. CT and MRI were carried out on that patient. Despite both clinical and radiographic suspicions for intracranial forms of lymphoma, the patient was still difficult to diagnose. A definitive diagnosis was given after a surgery and histological examination, i.e. non-Hodgkin's lymphoma - large B-cell lymphoma. This case is of interest because of its rare intracranial localization of the lymphoma. The knowledge of CT and MRI images of the intracranial form of lymphoma may help diagnosing, but images should be interpreted together with the clinical and paraclinical results Hodgkin's and non-Hodgkin's) is a disease of the lymphatic system where the central neural system is affected in very rare cases. According to different authors the frequency of cases with lymphoma where the neural system is affected varies between 0, 2 % and 0, 5 %, and the primary cerebral lymphoma accounts for about 1-2% of ail brain neoplasms.

    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.

    Lymphoma is frequently present in patients with acquired immunodeficiency (AIDS). But unlike in the general population, the appearance of lymphoma in patients with AIDS is extremely varied. The computed tomographic scans, chest radiographs, and subsequent hospital courses of 15 patients with AIDS-related lymphoma are presented. The patients presented with isolated pleural effusion (six patients), pleural and pericardial effusion (one patient), pulmonary infiltrates (five patients), and mediastinal adenopathy (three patients). This varied manner of presentation of lymphoma in AIDS patients should be recognized if diagnosis is to be made in the earlier stages of presentation

    We report a case of primary small-cell lymphocytic lacrimal gland lymphoma in a male diagnosed with primary antiphospholipid syndrome. These rare lymphomas are usually presented in the clinic as disseminations secondary to chronic lymphocytic leukaemia, and the primary site is rare in the orbit. Non-Hodgkin lymphomas are a heterogeneous group of tumours. Although treatment in the IE stage is usually radiotherapy, due to its association with antiphospholipid syndrome, systemic treatment with rituximab was administered.

    Thyroid mucosa-associated lymphoid tissue (MALT) lymphoma is a type of extranodal lymphoma with a favorable prognosis. To provide information on long-term outcomes that would facilitate establishment of the optimal management strategy for thyroid lymphoma. Medical records of 107 patients (median age 67 years, 20 males, 87 females) who were diagnosed with localized thyroid MALT lymphoma stage IE or IIE at Ito Hospital were retrospectively reviewed. Overall and event-free survival (EFS). Initial treatments included radiation therapy (RT) alone (n = 58), combined modality therapy (CMT) (n = 48), or chemotherapy alone (n = 1). All 107 patients responded to the treatment, six of whom experienced relapse. Only one patient died of lymphoma. The 5-year overall survival (OS) and EFS rates were 94% [95% confidence interval (CI), 87% to 97%] and 92% (95% CI, 85% to 95%), respectively, and the 10-year OS and EFS rates were 91% (95% CI, 83% to 95%) and 84% (95% CI, 74% to 90%), respectively. Of the 106 patients with information available on adverse events, 71 patients (67%) developed hypothyroidism after primary thyroid lymphoma treatment. The CMT group showed additional chemotherapy-induced adverse reactions in the form of neutropenia, neuropathy, constipation, and pneumonia. The 5-year OS rates of patients treated with CMT and RT were 93% (95% CI, 81% to 98%) and 94% (95% CI, 84% to 98%), respectively. Long-term outcomes of localized thyroid MALT lymphoma are favorable with all initial treatment modalities. Copyright © 2017 Endocrine Society

    115 patients with lymphoid tumours presenting in the orbit were seen between 1970 and 1984. The histological types were high-grade malignant lymphoma - 18, low-grade malignant lymphoma - 43, and indeterminate lymphocytic lesions - 54. Eighteen patients were found to have disseminated lymphoma at presentation. The majority of the patients received radiotherapy to the orbit; local control was achieved in all cases and the ocular morbidity from radiotherapy was low with 11 patients developing lens opacities and 5 a dry eye. Survival of patients with stage I low-grade lymphoma adn indeterminate lymphocytic lesions was similar to that of a normal population of the same age distribution. The clinic features and dissemination pattern of the low-grade malignant lymphomata and the indeterminate lymphocytic lesions were identical, suggesting that most, if not all, lymphoid masses presenting in the orbit are neoplastic rather than reactive in nature. 28 refs.; 4 figs.; 5 tabs

    Full Text Available Purpose: To report a case of a patient with primary vitreoretinal lymphoma masquerading as retinitis. Methods: Retrospective review of the patient's clinical, histopathological and imaging records. Results: Cytopathology was negative for malignancy, and preliminary polymerase chain reaction results supported the diagnosis of varicella zoster virus retinitis. Therefore, the patient was treated with antiviral therapy. However, under this treatment, the retinitis progressed. As a result, primary vitreoretinal lymphoma was suspected, and empirical treatment with intravitreal methotrexate injections was started. Under this treatment, the ocular features improved. Five months after initial ocular presentation and ocular resolution, the patient presented with central nervous system lymphoma. Conclusion: This case should raise the awareness of the variable clinical presentations, the challenging diagnosis and treatment of primary vitreoretinal lymphoma. All cases should be continuously systemically evaluated.

    Splenic marginal zone lymphoma (SMZL) is a rare non-Hodgkin lymphoma. We sought to identify prognostic factors and define outcomes in a cohort of 64 patients with SMZL who were treated at two large academic medical centers in North America in the rituximab era. Over a median follow-up of 37.8 (range 6-167.1) months, Kaplan-Meier estimate of median OS was 156.3 months and median PFS was 52.9 months. On univariate analysis, baseline hemoglobin marginally significant with regard to OS (p = 0.056). Splenectomy was not predictive of OS or PFS (p = 0.563 and 0.937, respectively). Transformation to diffuse large B-cell lymphoma occurred in four (6.3%) patients during the observation period. OS was comparable to contemporaneous cohorts of patients with extranodal and nodal marginal lymphomas and FLIPI score was highly predictive for inferior PFS and OS when all three cohorts were analyzed together. Outcomes of SMZL, in our series, were excellent, with a median OS of >13 years. Low hemoglobin and high-risk FLIPI were associated with inferior outcomes.

    The aim of this study was to assess the usefulness of positron emission tomography/computed tomography in staging, prognosis evaluation and restaging of patients with follicular lymphoma. A retrospective study was performed on 45 patients with untreated biopsy-proven follicular lymphoma who underwent 18 F-fluorodeoxyglucose PET/CT (FDG PET/CT) and CT before and after chemoimmunotherapy induction treatment (rituximab combined with cyclophosphamide, doxorubicin, vincristine and prednisone). PET/CT detected more nodal (+51%) and extranodal (+89%) lesions than CT. PET/CT modified Ann Arbor staging in eight patients (18%). Five patients (11%) initially considered as being early stage (I/II) were eventually treated as advanced stage (III/IV). In this study, an initial PET/CT prognostic score was significantly more accurate than the Follicular Lymphoma International Prognostic Index score in identifying patients with poor prognosis (i.e. patients with incomplete therapeutic response or early relapse). The accuracy of PET/CT for therapeutic response assessment was higher than that of CT (0.97 vs 0.64), especially due to its ability to identify inactive residual masses. In addition, post-treatment PET/CT was able to predict patients' outcomes. The median progression-free survival was 48 months in the PET/CT-negative group as compared with 17.2 months for the group with residual uptake (p -4 ). FDG PET/CT is useful for staging and assessing the prognosis and therapeutic response of patients with follicular lymphoma. (orig.)

    During the past decade, mantle-cell lymphoma has been established as a new disease entity. The normal counterparts of the cells forming this malignant lymphoma are found in the mantle zone of the lymph node, a thin layer surrounding the germinal follicles. These cells have small to medium-sized nuclei, are commonly indented or cleaved, and stain positively with CD5, CD20, cyclin D1, and FMC7 antibodies. Because of its morphological appearance and a resemblance to other low-grade lymphomas, many of which grow slowly, this lymphoma was initially thought to be an indolent tumour, but its natural course was not thoroughly investigated until the 1990s, when the BCL1 oncogene was identified as a marker for this disease. Mantle-cell lymphoma is a discrete entity, unrelated to small lymphocytic or small-cleaved-cell lymphomas.

    The use of 18F-fluoro-deoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in primary gastric lymphoma (PGL) is challenging due to physiologic FDG activity in the stomach and variability in the degree of uptake in various histologic subtypes. This study assesses FDG avidity and PET/CT patterns in newly diagnosed PGL. Sixty-two PET/CT studies of newly diagnosed PGL were reviewed (24 low-grade mucosa-associated lymphoid tissue [MALT], 38 aggressive non-Hodgkin's lymphoma [AGNHL]). FDG avidity, patterns (focal/diffuse), and intensity (visually vs. the liver and SUVmax) were assessed and compared to 27 controls. Gastric CT abnormalities and extragastric sites were recorded. Gastric FDG uptake was found in 55/62 (89%) PGL (71% MALT vs. 100% AGNHL, p < 0.001) and 63% controls. A diffuse pattern was found in 60% PGL (76% MALT vs. 53% AGNHL, p = NS) and 47% controls. FDG uptake higher than liver was found in 82% PGL (58% MALT vs. 97% AGNHL, p < 0.05) and 63% controls. SUVmax in FDG-avid PGLs was 15.3 ± 11.7 (5.4 ± 2.9 MALT vs. 19.7 ± 11.5 AGNHL, p < 0.001) and 4.6 ± 1.4 in controls. CT abnormalities were found in 79% PGL (thickening, n = 49; ulcerations, n = 22). Extra-gastric FDG-avid sites were seen in none of MALT, but 61% of AGNHL (nodal, n = 18; nodal and extranodal, n 5). FDG avidity was present in 89% of PGLs, including all patients with AGNHL but only 71% of MALT. FDG uptake can be differentiated, in particular in AGNHL-PGL, from physiologic tracer activity by intensity but not by pattern. Extragastric foci on PET and structural CT abnormalities are additional parameters that can improve PET/CT assessment of PGL. Defining FDG avidity and PET/CT patterns in AGNHL and a subgroup of MALT-PGL before treatment may be important for further monitoring therapy response. (orig.)

    Objective: To explore the value of {sup 18}F fluorodeoxy-glucose (FDG) positron emission tomography (PET) in Burkitt's lymphoma. Methods: All Burkitt's lymphoma patients referred for FDG PET or FDG PET/computed tomography (CT) exams at our institution from June 2003 to June 2006 were included. Selected patients were followed and clinical information was reviewed retrospectively. Results from FDG PET-PET/CT, as blindly reviewed by a consensus of two experienced readers, were compared with the status of the disease as determined by other laboratory, clinical and imaging exams and clinical follow-up. FDG PET-PET/CT results were classified as true positive or negative and false positive or negative. The degree of FDG uptake in the positive lesions was semiquantified as maximum standard uptake value (SUVmax). Results: Fifty-seven FDG PET-PET/CT exams were done in 15 patients. Seven exams were done for initial staging, 8 during and 14 after the completion of therapy, and 28 for disease surveillance. For nodal disease FDG PET-PET/CT was true positive in 8, true negative in 47 and false positive in 2 exams (sensitivity 100%, specificity 96%). For extranodal disease FDG PET-PET/CT was true positive in 6, true negative in 48 and false positive in 3 exams (sensitivity 100%, specificity 94%). The mean SUVmax for the positive nodal lesions was 15.7 (range 6.9-21.7, median 18.5) and for extranodal lesions was 14.2 (range 6.2-24.3, median 12.4). Conclusions: FDG PET-PET/CT is sensitive for the detection of viable disease in Burkitt's lymphoma. Affected areas demonstrated high degree of uptake that was reversible upon successful implementation of treatment.

    Primary lymphoma of the trachea is extremely rare and clinical presentation is nonspecific. CT findings are focal tracheal narrowing caused by a solitary mass or polypoid thickening of the tracheobronchial wall caused by diffuse infiltration of the submucosa. However, US finding of primary lymphoma of the trachea has been not reported. We experienced a case of primary lymphoma of the trachea presenting as a homogenous hypoechoic mass, and discuss ultrasonographic and CT findings of the case

    A rare case of bilateral primary malignant lymphoma of breast in a 76 year old woman is presented. The lesion was examined by electron microscopy and immunochemistry. The diagnosis of primary malignant lymphoma remains a diagnosis by exclusion and requires extensive work-up to exclude widespread malignant process. The behaviour of this malignancy tends to be an aggressive one and the prognosis is generally poor.

    Chemotherapy represents the most important therapeutic option in malignant lymphomas. Low to intermediate risk Hodgkin's disease is treated by a combination of chemotherapy and radiation. The new chemotherapy protocol BEACOPP has improved the outcome of advanced stages in comparison with the internationally accepted standard protocol COPP/ABVD. Dependent on the initial staging, cure rates between 50 and 95% can be achieved. Indolent non-Hodgkin's lymphomas usually present in advanced stages of disease. Chemotherapy in these cases has palliative character and aims at improving patients'quality of life and at avoiding complications due to the disease. In aggressive and very aggressive non-Hodgkin's lymphoma chemotherapy is curative and must be initiated immediately irrespective of the staging results. The efficacy of the standard protocol CHOP (cyclophosphamide,doxorubicin, vincristine and prednisone), that was established in the 1970s, has recently been improved by shortening of the therapy interval (CHOP-14 vs.CHOP-21),addition of etoposide (CHOEP) and combination with the monoclonal antibody rituximab (R-CHOP). The value of high dose chemotherapy with stem cell transplantation has been shown unequivocally only for aggressive non-Hodgkin lymphoma and relapsed Hodgkin's disease responsive to chemotherapy. The therapeutic strategy of malignant lymphomas is likely to be improved within the next years due to the introduction of novel cytostatic agents, the broadening application of monoclonal antibodies,upcoming new transplantation procedures and the development of substances with molecular targets.To rapidly increase our current knowledge on the topic it is mandatory to include patients into the large national and international multicenter studies.

    The purpose of this study is to describe the sonographic appearance of lymphoma of the gastrointestinal tract in dogs. A retrospective review was conducted and patients with gastrointestinal lymphoma diagnosed by histopathology (including immunohistochemistry, where available) or cytology that had an abdominal ultrasound were included. Four of 15 (26·7%) cases with histopathologically confirmed lymphoma exhibited no sonographic abnormalities. In the dogs with sonographic abnormalities, features including intestinal wall thickness and the presence or absence of wall layering were highly variable. Clinical signs pertaining to the gastrointestinal tract were also unreliable markers of gastrointestinal lymphoma, with weight loss, vomiting, and diarrhoea being uncommon presenting complaints; intestinal obstruction was not present in any patient. The sonographic appearance of gastrointestinal lymphoma in dogs is non-specific. Gastrointestinal lymphoma in dogs should be maintained as a differential diagnosis despite a sonographically normal appearing bowel. © 2013 British Small Animal Veterinary Association.

    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.

    The case is presented of a 43 year-old male patient with chronic follicular conjunctivitis, negative bacterial serology, and refractory to local treatment. The incisional biopsy performed showed to be consistent with reactive lymphoid hyperplasia. A year later, a new incisional biopsy showed follicular lymphoma, with no systemic involvement, and he was treated with local radiotherapy. When a chronic follicular conjunctivitis is refractory to treatment, it is essential to perform an incisional biopsy to establish the histopathological diagnosis that can range from chronic inflammation, reactive lymphoid hyperplasia to lymphoma. Follicular lymphoma is rare among conjunctival lymphomas, and the staging is indispensable for the correct therapeutic approach. Copyright © 2014 Sociedad Española de Oftalmología.

    A 66-year-old man presented with deteriorated bradykinesia, gait disturbance, disorientation, and urinary incontinence for three weeks. Magnetic resonance imaging (MRI) showed dilatation of the ventricles. Cerebrospinal fluid (CSF) examination demonstrated lymphocytic pleocytosis, elevation of protein levels, and decreased of glucose levels. A gadolinium-enhanced MRI revealed lesions in the ventricular wall and choroid plexus, mimicking ventriculitis. No evidence of bacterial, fungal, mycobacterial, or viral infections were observed in the CSF. Flow cytometry of CSF showed predominance of CD20+, λ+ cells. PCR examination of CSF revealed positive IgH gene rearrangement, suggesting B cell lymphoma. Endoscopic brain biopsy showed diffuse large B cell lymphoma. As the patient had no evidence of lymphoma in the other organs, we made a diagnosed of primary central nervous system lymphoma (PCNSL). A limited intraventricular spread of PCNSL is rare but important as one of differential diagnosis of ventriculitis.

    Primary breast lymphomas, a rare subtype of non-Hodgkin's lymphoma, represent 0.04 to 0.5% of all breast cancers, 0.38 to 0.7% of all lymphomas, and 1.7 to 2.2% of extranodal lymphomas. The treatment choice is based on chemotherapy containing anthracycline and rituximab. Surgery is limited to being less invasive and only for diagnostic purposes. Radiotherapy has an important role as consolidation therapy, particularly in patients with negative nodes. A 70 year old woman with a breast nodule in the left upper outer quadrant, with slow growth, expansive, painless, and accompanied by skin changes, malaise, weight loss, fatigue, chill, and sweating. There was tissue replacement by the mammary gland tumour, skin changes due to invasion, and a 5cm axillary lymphadenopathy. The mammography showed skin thickening and a dense pattern of 80% of breast tissue replacement, and the lymphadenopathy with loss of radiolucent centre and soft tissue invasion. The biopsy confirmed a diffuse high grade large cell lymphoma. She received an Rituximab (R-CHOP) chemotherapy scheme and radiotherapy with tangential and supraclavicular and axillary fields. After completing the chemotherapy, the patient is on follow-up, and at 15 months she is alive without disease activity. Primary lymphoma of the breast is a rare entity. Multimodal treatment with combined chemo-radiotherapy is the cornerstone. Surgery is reserved only for diagnostic purposes. Copyright © 2015 Academia Mexicana de Cirugía A.C.

    Lymphoma patients are at increased risk of thromboembolic events but thromboprophylaxis in these patients is largely underused. We sought to develop and validate a simple model, based on individual clinical and laboratory patient characteristics that would designate lymphoma patients at risk for thromboembolic event. The study population included 1,820 lymphoma patients who were treated in the Lymphoma Departments at the Clinics of Hematology, Clinical Center of Serbia and Clinical Center Kragujevac. The model was developed using data from a derivation cohort (n = 1,236), and further assessed in the validation cohort (n = 584). Sixty-five patients (5.3%) in the derivation cohort and 34 (5.8%) patients in the validation cohort developed thromboembolic events. The variables independently associated with risk for thromboembolism were: previous venous and/or arterial events, mediastinal involvement, BMI>30 kg/m(2) , reduced mobility, extranodal localization, development of neutropenia and hemoglobin level 3). For patients classified at risk (intermediate and high-risk scores), the model produced negative predictive value of 98.5%, positive predictive value of 25.1%, sensitivity of 75.4%, and specificity of 87.5%. A high-risk score had positive predictive value of 65.2%. The diagnostic performance measures retained similar values in the validation cohort. Developed prognostic Thrombosis Lymphoma - ThroLy score is more specific for lymphoma patients than any other available score targeting thrombosis in cancer patients. Am. J.

    Full text: Lymphoma (Hodgkin's and non-Hodgkin's) is a disease of the lymphatic system where the central neural system is affected in very rare cases. According to different authors the frequency of cases with lymphoma where the neural system is affected varies between 0.2% and 0.5%, and the primary cerebral lymphoma accounts for about 1-2% of all brain neoplasms. The intracranial form of lymphoma is usually a late onset of the disease with serious and potentially fatal complications for the patient. These complications usually appear several years after diagnosing the disease, but the cerebral lymphoma may occur even in patients who are in remission, which is actually the case with our patients. We present you two cases - a 38-year-old female and a 48-year-old male, who were hospitalized in Neuro ward with the following complaints: loss of speech for a few minutes, dizziness, weakness, tingling and shuffling of one of the legs. Those patients were diagnosed with histological B-cell non-Hodgkin's lymphoma and Hodgkin's lymphoma, several years ago. CT and MRI were carried out on the patients. Despite both clinical and radiographic suspicions for intracranial forms of lymphoma, the patients were still difficult to diagnose. A definitive diagnosis was given after a surgery and histological examination, i.e. non- Hodgkin's lymphoma - large B-cell lymphomas, and Hodgkin's lymphoma. These cases are of interest because of their rare intracranial localization of the lymphoma. The knowledge of CT and MRI images with the intracranial form of lymphoma may help diagnosing, but images should be interpreted together with the clinical and paraclinical results

    Peritoneal spread of non-Hodgkin lymphoma is rare: fewer than three percent of persons afflicted with this disease develop peritoneal spread. Pericardial involvement by non-Hodgkin lymphoma is equally rare. We report an instance of peritoneal and pericardial spread in a patient with non-Hodgkin lymphoma that was detected only by CT scan. The peritoneal lesions were not visible by ultrasound examination. A pertinent review of the literature is presented. (author)

    Full Text Available Primary bone lymphoma (PBL is an uncommon tumor accounting for approximately 4-5% of extra nodal lymphoma and less than 1% of all non-Hodgkin′s lymphoma. Disease may be complicated at presentation by pathological fracture or spinal cord compression. Diffuse large-B-cell lymphoma (DLBCL accounts for the majority of cases of PBL. Owing to its rarity, only a few retrospective studies have been published addressing the prognosis and treatment of primary bone lymphoma. In this paper, we report our experience with two cases of PBL treated with chemotherapy and radiotherapy and review literature to elucidate the optimal treatment of primary bone lymphoma.

    Full Text Available Lymphoma is a lymphoid tumor that originates in hematopoietic organs such as lymph node, spleen or liver. In dogs, the overall prevalence of cardiac tumors was estimated to be only 0.19% based on the results of the survey of a large database, and lymphomas accounts for approximately 2% of all cardiac tumors. In general, the involvement of the myocardium is rarely described in canine lymphoma. Currently, there is no evidence of a viral association with primary cardiac lymphoma in dogs, but other types of immunosuppression may contribute to abnormal events, such as involvement primary cardiac. The aim of this study was to analyze a case of sudden death of a bitch, SRD, aged 10, who had the final diagnosis of cardiac lymphoma.

    We present four cases of primary cerebral lymphoma in non-immunodepressed adult patients. All cases were dsemonstrated with pathological study. CAT study showed solitary or multiple isodense lesions, which incorporated avidly and homoneneously the contrast. Arteriography performed in three patients and magnetic resonance, performed in one did not help for diagnosis. We also review the radiological findings obtained with different imaging methods, and suggest the criteria which could be useful for early diagnosis (Author)

    We report a case of visceral leishmaniasis in a 66-year-old female with a history of MALT lymphoma in the gastrointestinal tract. The patient presented with major hemorrhage per rectum and perforation of the small intestine. Due to unexplained decreasing platelets, lymphoma bone marrow involvement...... was suspected and bone marrow examination was performed. Surprisingly, Leishman-Donovan bodies were detected. The low platelet count, caused by the combination of MALT lymphoma and visceral leishmaniasis, appears to have aggravated the symptoms of the intestinal lymphoma. Leishmaniasis should be suspected even...... among asymptomatic patients with immune compromising illnesses and a travel history to areas where leishmaniasis is endemic....

    Full Text Available Case summary A 14-year-old neutered male Siamese cat was presented with a 3 month history of lethargy, inappetence, dehydration, hindlimb ataxia and intermittent proprioceptive deficits in the hindlimbs. Physical examination revealed low body condition score (1.75/5, pallor and bilateral basilar grade II/VI systolic heart murmur. Neurological examination revealed hindlimb ataxia, severe atrophy of the hindlimb musculature, intermittent hindlimb proprioceptive deficits and normoreflexia. Clinicopathological investigations revealed non-regenerative anaemia (haematocrit 0.17 l/l; reference interval [RI] 0.24–0.45 l/l and increased feline pancreatic lipase concentration (Spec fPL test [IDEXX] 8.3 μg/l; RI 0.1–3.5 μg/l. Feline leukaemia virus antigen and feline immunodeficiency virus antibody tests were negative. Thoracic and abdominal imaging revealed a soft tissue structure in the area of the thoracoabdominal aorta. CT confirmed a periaortic contrast-enhancing mass extending from the level of T9–L2, with associated intervertebral infiltration at the level of T11–T12. Post-mortem examination confirmed the presence of a solid, white, multinodular, well-demarcated mass encircling the aorta extending from T9–L2. Based on histopathology and immunohistochemistry, a diagnosis of B-cell lymphoma was made. Lymphoma was also identified histopathologically within the kidneys and spleen. Evidence of mild Wallerian degeneration was present within the spinal cord, indicating compression at the level of the periaortic mass. Relevance and novel information To our knowledge, this is the first report of periaortic lymphoma in the cat. Although periaortic tumours are exceptionally rare in veterinary medicine, lymphoma should be considered as a differential in cats.

    Full Text Available Os linfomas extralinfonodais representam aproximadamente 1/3 de todos os linfomas não Hodgkin (LNH e, embora possam ter início em qualquer tecido, mais frequentemente acometem o trato gastrointestinal, sendo o estômago o órgão responsável pela grande maioria dos casos. Os linfomas primários gástricos são comumente LNH, sendo representados em mais de 95% dos casos pelo linfoma difuso de grandes células B e pelo linfoma MALT (mucosa associated lymphoid tissue. De evolução indolente, o linfoma MALT destaca-se por ser um modelo de câncer secundário à estimulação antigênica crônica exercida por uma bactéria denominada Helicobacter pylori (HP. No outro polo, situa-se o linfoma difuso de células B (LDGCB, que, de patogênese duvidosa, pode tratar-se de uma transformação de LNH MALT ou ainda se caracterizar por um linfoma "de novo". Neste estudo, revisamos a literatura, enfatizando aspectos importantes à prática clínica destes linfomas.Extranodal lymphomas account for about 30% of all non-Hodgkin lymphomas (NHL, and although they can originate in any tissue, the gastrointestinal tract is the most commonly affected structure with the stomach being the most common subtype. Diffuse Large B cell lymphoma (DLBCL and MALT (mucosa associated lymphoid tissue lymphoma account for more than 95% of the cases of gastric lymphoma. The indolent development of MALT lymphoma stands out as it is a type of cancer subject to chronic antigen stimulation by the Helicobacter pylori bacteria. Conversely, diffuse large B cell lymphomas, whose pathogenesis is uncertain, can be a transformation from MALT NHL or perhaps a new type of lymphoma. In this study we carried out a review of the literature, stressing the key aspects of these lymphomas in the clinical practice.

    Primary effusion lymphoma, a human herpesvirus 8 (HHV8)-associated lymphoma, is uncommon, and it is usually seen in human immunodeficiency virus (HIV)-infected patients. It presents as a body cavity-based lymphomatous effusion, but several cases of the so-called solid primary effusion lymphoma presenting as solid tumors without associated lymphomatous effusion have been reported. They have similar clinical, histopathological and immunophenotypical features. Most of them have a B-cell genotype. This suggests the solid variant may represent a clinicopathological spectrum of primary effusion lymphoma. We report a case of HHV8-associated lymphoma histopathologically and immunophenotypically mimicking cutaneous anaplastic large cell lymphoma. The patient was a 31-year-old HIV-seropositive man presenting with skin nodules over his right thigh. Biopsy of the nodules showed anaplastic large cells infiltrating the dermis. These malignant cells strongly expressed CD3, CD30 and CD43. Cutaneous anaplastic large T-cell lymphoma was initially diagnosed, but further tests, including immunoreactivity for HHV8 protein and clonal rearrangements of immunoglobulin genes, confirmed the diagnosis of HHV8-associated B-cell lymphoma with aberrant T-cell marker expression. This case provides an example of solid primary effusion lymphoma mimicking cutaneous anaplastic large T-cell lymphoma and highlights the importance of HHV8 immunohistochemistry and molecular tests in the diagnosis of HHV8-associated lymphoma with a cutaneous presentation.

    2011-09-01

    Full Text Available Abstract Introduction Discordant lymphomas are rare entities characterized by the simultaneous presence of two distinct types of lymphomas in different anatomic sites. We describe a very rare case of simultaneous occurrence of splenic mantle cell lymphoma and marginal zone lymphoma involving the bone marrow and peripheral blood. Case presentation We report the case of a 60-year-old asymptomatic Caucasian woman in whom discordant lymphomas were discovered when a slight lymphocytosis and a conspicuous splenomegaly were observed. The different morphological, immunophenotypical and immunohistochemical features found in the different pathologic samples obtained from peripheral blood, bone marrow and spleen sections made it possible to differentiate two types of non-Hodgkin B-cell lymphomas: a mantle cell lymphoma infiltrating the spleen and a marginal zone lymphoma involving both the bone marrow and peripheral blood. Since a similar IgH gene rearrangement was found both in the bone marrow and in the spleen, the hypothesis of a common origin, followed by a different clonal selection of the neoplastic lymphocytes may be taken into consideration. Conclusion Our case emphasizes the usefulness of investigating simultaneous specimens from different anatomic sites from the same patient and the relevant diagnostic role of splenectomy.

  16. Endometrial Polyps and Benign Endometrial Hyperplasia Present Increased Prevalence of DNA Fragmentation Factors 40 and 45 (DFF40 and DFF45) Together With the Antiapoptotic B-Cell Lymphoma (Bcl-2) Protein Compared With Normal Human Endometria.

    DNA fragmentation factor 40 (DFF40) is a key executor of apoptosis. It localizes to the nucleus together with DNA fragmentation factor 45 (DFF45), which acts as a DFF40 inhibitor and chaperone. B-cell lymphoma (Bcl-2) protein is a proven antiapoptotic factor present in the cytoplasm. In this study, we aimed to investigate DFF40, DFF45, and Bcl-2 immunoexpression in endometrial polyps (EPs) and benign endometrial hyperplasia (BEH) tissue compared with that in normal proliferative endometrium (NPE) and normal secretory endometrium (NSE) as well as normal post menopausal endometrium (NAE). This study used archived samples from 65 and 62 cases of EPs and BEH, respectively. The control group consisted of 52 NPE, 54 NSE, and 54 NAE specimens. Immunohistochemistry was used to detect DFF40, DFF45, and Bcl-2. DFF40, DFF45, and Bcl-2 were more highly expressed in the glandular layer of EPs and BEH compared with the stroma, and this was not influenced by menopausal status. Both glandular and stromal expression of DFF40, DFF45, and Bcl-2 were significantly higher in EPs compared with NPE, NSE, and NAE. Glandular BEH tissue showed significantly higher DFF40, DFF45, and Bcl-2 expression than in NPE, NSE, and NAE. No differences in the glandular expression of DFF40, DFF45, and Bcl-2 were observed between EP and BEH tissues, while Bcl-2 stromal expression in BEH was significantly lower than in EPs. Glandular, menopause-independent DFF40, DFF45, and Bcl-2 overexpression may play an important role in the pathogenesis of EPs and BEH.

    Full Text Available Primary non-Hodgkin’s lymphoma (NHL of the breast constitutes 0.04%-0.53% of all malignancies and 2.2% of extra nodal lymphomas. In total, 7%-8% of all B-cell lymphomas are the mucosa-associated lymphoid tissue (MALT type, of which up to 50% of primary gastric MALT lymphoma. Herein we present a patient with breast MALT lymphoma that transformed to diffuse large B-cell lymphoma (DLBCL. A 69-year-old female presented with a mass on her left breast. Physical examination showed a 3 × 3-cm mass located 1 cm from the areola on the upper lateral quadrant of the breast at the 1 o’clock position, which was fixed and firm. Excisional biopsy was performed and pathologic examination of the specimen showed MALT lymphoma transformation to DLBCL. The patient was staged as II-EA. The rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP protocol was scheduled as treatment. Following 6 courses of R-CHOP, 2 additional courses of rituximab were administered. Positron emission tomography (PET-CT was done at the end of the treatment. PET showed that the patient was in complete remission. At the time this report was written, the patient was being followed-up at the outpatient clinic on a regular basis. Lymphoma of the breast is a rarity among malignant tumors of the breast. The most common type of lymphoma is DLBCL. Breast MALT lymphoma is extremely rare. Primary MALT lymphoma of the breast can transform from low grade to high grade and recurrence is possible; therefore, such patients should be monitored carefully for transformation.

    Marginal zone lymphomas (MZLs) are indolent disorders composed of 3 subtypes: extranodal marginal zone lymphoma (MALT), splenic marginal zone lymphoma (SMZL), and nodal marginal zone lymphoma (NMZL). Early-stage MALT is treated with radiotherapy or antibiotics, and advanced MALT and NMZL are managed with either watch and wait or chemotherapy. SMZLs are treated with splenectomy or rituximab. However, because these approaches have failed to cure patients with SMZL and NMZL, we have systematically used upfront chemotherapy for them, as well as for advanced MALT. We report the outcomes of this approach. A total of 44 patients with MZL were identified from our database and divided into 2 groups. Group 1 (22 with early-stage MALT) patients received either radiotherapy (n = 17) or antibiotics with or without surgery (n = 5). Group 2 included 9 patients with advanced MALT, 9 with SMZL, and 4 with NMZL. Group 2 was treated with FND-R (fludarabine 25 mg/m 2 on days 1 to 3, mitoxantrone 10 mg/m 2 on day 1, dexamethasone 20 mg on days 1 to 5, and rituximab 375 mg/m 2 on day 1; n = 14) or CHOP-R (cyclophosphamide 750 mg/m 2 on day 1, doxorubicin 50 mg/m 2 on day 1, vincristine 2 mg intravenous push on day 1, prednisone 100 mg/m 2 orally on days 1 to 5, rituximab 375 mg/m 2 on day 1; n = 8), followed by maintenance rituximab for 70%. All patients achieved complete remission, and only 2 patients in group 1 had developed a relapse at 70 and 75 months. Both relapses were stage I MALT that had initially been treated with radiotherapy. Both were salvaged with FND-R and remained free of disease at 27 and 39 months after the relapse. At 10 years, the failure-free survival for the 44 patients was 80% and the overall survival was 100%. None of the patients in group 2 developed a relapse. The long-term toxicities have been acceptable. The excellent responses using upfront chemotherapy for MZL suggests that this disorder is curable. Our results should be confirmed in a prospective trial

    A literature review was performed on mantle cells lymphoma in the therapeutic schemes. The literature that has been used is published in journals of medicine specializing in hematology, oncology, radiation therapy, molecular biology and internal medicine. The literature review was performed to propose a scheme of treatment according to Costa Rica. Epigenetic alterations have been revealed in patients with mantle lymphoma on current researches. The mantle lymphoma pathology has been described in various forms of clinical and histological presentation, stressing the importance of detailing the different methods and diagnostic reports. Working groups have proposed and developed various chemotherapy regimens and concluded that CHOP alone is without effect in mantle cell lymphoma unlike R-hyper-CVAD, CHOP / DHAP, high-dose Ara-C. Researchers have tried to develop new treatments based vaccines, use of modified viruses, specific monoclonal antibodies. The classic treatment has been triple intrathecal therapy. The central nervous system has been one of the most momentous sites of mantle cell lymphoma infiltration because poorer patient prognosis [es

  5. PET imaging in pediatric Hodgkin's lymphoma

    2004-01-01

    Advances in diagnostic imaging technology, especially functional imaging modalities like positron emission tomography (PET), have significantly influenced the staging and treatment approaches used for pediatric Hodgkin's lymphoma. Today, the majority of children and adolescents diagnosed with Hodgkin's lymphoma will be cured following treatment with noncross-resistant combination chemotherapy alone or in combination with low-dose, involved-field radiation. This success produced a greater appreciation of long-term complications related to radiation, chemotherapy, and surgical staging that prompted significant changes in staging and treatment protocols for children and adolescents with Hodgkin's lymphoma. Contemporary treatment for pediatric Hodgkin's lymphoma uses a risk-adapted approach that reduces the number of combination chemotherapy cycles and radiation treatment fields and doses for patients with localized favorable disease presentation. Advances in diagnostic imaging technology have played a critical role in the development of these risk-adapted treatment regimens. The introduction of computed tomography (CT) provided an accurate and non-invasive modality to define nodal involvement below the diaphragm that motivated the change from surgical to clinical staging. The introduction of functional imaging modalities, like positron emission tomography (PET) scanning, provided the means to correlate tumor activity with anatomic features generated by CT and modify treatment based on tumor response. For centers with access to this modality, PET imaging plays an important role in staging, evaluating tumor response, planning radiation treatment fields, and monitoring after completion of therapy for pediatric Hodgkin's lymphoma.

    Malignant lymphoma of the central nervous system has been found more and more often in recent years, partly because of the increased use of radiation and such drugs as steroids and antibiotics. However, the definite diagnosis of this disease is difficult until histological verification has been done by operation or autopsy. Since the revolutionary development of computed tomography, however, several reports have been presented, on the computed tomography of malignant lymphoma of the thorax and abdomen. Nevertheless, only a few cases of intracranial malignant lymphoma have been reported. The purpose of this paper, using four patients, is to emphasize the value of computed tomography in the diagnosis of intracranial malignant lymphoma. The characteristic CT findings of intracranial malignant lymphoma may be summarized follows: (1) the tumors are demonstrated to be well-defined, nodular-shaped, and homogenous isodensity - or slightly high-density - lesions in plain scans, and the tumors homogenously increase in density upon contrast enhancement; (2) the disease always has multifocal intracranial lesions, which are shown simultaneously or one after another, and (3) perifocal edema is prominent around the tumors in the cerebral hemisphere.

    OBJECTIVE: Nasopharyngeal (NP) non-Hodgkin's lymphoma (NHL) is an uncommon tumour. The aim of the study was to describe the appearances on CT and MR imaging, and identify the features which help to distinguish NPNHL from other NP tumours. MATERIALS AND METHODS: The CT (n=8) and MR (n=10) images of 14 patients with NPNHL were reviewed retrospectively. Patients with NPNHL were divided into primary NPNHL, where the primary tumour was in the NP (n=7) and secondary NPNHL where the primary tumour was at another extranodal site in the head and neck (n=7). All NPNHL were assessed for tumour size and distribution, appearance and local tumour invasion, in addition lymphadenopathy was assessed in primary NPNHL. RESULTS: The NPNHL ranged in size from 20-75 mm (mean of 55 mm for primary and 30 mm for secondary NHL) and were homogeneous on CT in eight (100%) and MR in seven (70%) and mildly heterogeneous on MR in three (30%) patients. NPNHL involved all walls of the NP in 10 (71%) and extended in an exophytic fashion to fill the NP cavity in six (43%). Deep tumour invasion was present in two (14%) both patients with primary NHL, the extent and volume of this tumour invasion was small and involved the prevertebral muscles (n=2), parapharyngeal fat space (n=1) and skull base (n=1). Primary NPNHL extended superficially in five (71%) to involve the nasal cavity (n=3) and oropharynx (n=2) and lymphadenopathy was present in five (71%) being bilateral and involving multiple nodal sites (n=4) with necrosis (n=2) and matting (n=3). CONCLUSION: NPNHL is a homogeneous tumour that tends to diffusely involve all walls of the nasopharynx and spread in an exophytic fashion to fill the airway, rather than infiltrating into the deep tissues. Deep tumour infiltration, when it occurs, is found in those patients with primary NHL and is usually limited in extent and of small volume. Primary NHL more commonly spreads superficially to involve the nasal cavity or oropharynx, lymphadenopathy is frequent

    Malignant lymphomas, primary tumors of the lymphoid tissues, were first described in 1832 by Thomas Hodgkin. The histological characteristics were later defined by Sternberg and Reed, and Virchow introduced the concept of lymphosarcoma in 1863. Today, these pathologies are grouped together under the synonymous terms hematosarcoma or malignant lymphoma, which are in turn divided into Hodgkin's disease (HD) and non-Hodgkin's malignant lymphomas (NHL). The therapy of lymphomas is controversial. The validity of treatment for asymptomatic patients is questioned, owing to the indolent course of many lymphomas. Results for histologically unfavorable forms are highly disparate. Exclusive radiotherapy has occasionally produced up to 78% disease-free survival at 5 years for truly localized stages. Today, however, use of chemotherapy/radiotherapy combinations is almost universal, with chemotherapy occasionally being used alone and providing 90% disease-free survival at 5 years. Chemotherapy is the main treatment for disseminated forms; the major associations include doxorubicin hydrochloride (Adriamycin), cyclophosphamide, vincristine sulfate, methotrexate, and prednisone. Radiotherapy is used more for adjuvant purposes. Synthesis of recent studies allows us to reasonably expect 40% relapse-free survival at 10 years and the establishment of a cure plateau in the near future

    Full Text Available Lymphomas occur by clonal expansion of lymphoid cells and have distinctive morphological and immunophenotypic features. Determination of canine lymphoma immunophenotype is useful for accurate prognosis and further therapy. In the suggested study, we performed an immunohistochemical evaluation of some cases with canine lymphoma diagnosed in the Department of Pathology (Faculty of Veterinary Medicine, Cluj-Napoca, Romania, in order to characterize them. The investigation included 39 dogs diagnosed with different anatomical forms of lymphoma, following necropsy analysis or assessment of biopsies. The diagnosis of lymphoma was confirmed by necropsy and histopathology (Hematoxylin-eosin stain examinations. The collected specimens were analyzed by immunohistochemistry technique (automatic method using the following antibodies: CD3, CD20, CD21 and CD79a. The analyzed neoplasms were characterized as follows: about 64.10% of cases were diagnosed as B-cell lymphomas, 33.34% of cases as T-cell lymphomas, whereas 2.56% of cases were null cell type lymphomas (neither B nor T. Most of multicentric (80%, mediastinal (60% and primary central nervous system lymphomas (100% had B immunophenotype, while the majority of cutaneous (80% and digestive (100% lymphomas had T immunophenotype. Immunohistochemical description of canine lymphomas can deliver some major details concerning their behavior and malignancy. Additionally, vital prognosis and efficacy of some therapeutic protocols are relying on the immunohistochemical features of canine lymphoma.

    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.

    Since the recognition of the anaplastic large-cell lymphomas in the 1980s, much has been learned about the diagnosis, clinical presentation, and treatment of these malignant conditions. The systemic and primary cutaneous types of anaplastic large cell lymphomas have been differentiated on clinical and immunophenotypical findings, but further research is required to elucidate their exact etiologies and pathogeneses. Primary cutaneous anaplastic large-cell lymphoma has a 95% disease-specific 5-year survival, owing partly to the relatively benign course of the disease and partly to the variety of effective treatments that are available. As with many other oncological diseases, new drugs are continually being tested and developed, with immunotherapy and biological response modifiers showing promise.

    Seventeen patients with initial presentation of lymphoma of the testis were evaluated at the Mayo Clinic between 1969 and 1979. The mean age of the patients was 69 years with 15 of the 17 patients age 60 and older at the time of diagnosis. All histologies were diffuse according to the Rappaport classification with 12 of 17 patients being histiocytic. Eleven of the 15 State I/sub E/A and II/sub E/A patients were treated with radiation therapy alone with doses ranging from 2,600 to 4,000 rad. Eight of these 11 Stage I/sub E/A patients experienced recurrence; in five of these eight, the first site of recurrence was Waldeyer's ring and adjacent structures. Four patients were treated initially with chemotherapy. In all four patients the lymphoma recurred, in two patients in the central nervous system (CNS). The survival rate at two years was 73% in Stage I/sub E/A patients and 25% in Stage II/sub E/A patients. There were no survivors at two years in those patients presenting with Stage IV disease. As patients with testicular lymphoma have a relatively high incidence of secondary involvement of Waldeyer's ring and the CNS, careful evaluation of these areas should be performed as part of the routine staging procedures. In view of the high incidence of secondary involvement of distant sites, systemic treatment should be given full consideration in addition to local irradiation as part of the initial treatment of patients with localized disease

    Canine nodal marginal zone lymphoma (nMZL) is classified as an indolent lymphoma. Such lymphomas are typified by low mitotic rate and slow clinical progression. While the clinical behaviour of canine splenic MZL has been described, characterized by an indolent course and a good prognosis following splenectomy, there are no studies specifically describing nMZL. The aim of this study was to describe the clinical features of and outcome for canine nMZL. Dogs with histologically confirmed nMZL undergoing a complete staging work-up (including blood analysis, flow cytometry [FC] on lymph node [LN], peripheral blood and bone marrow, imaging, histology and immunohistochemistry on a surgically removed peripheral LN) were retrospectively enrolled. Treatment consisted of chemotherapy or chemo-immunotherapy. Endpoints were response rate (RR), time to progression (TTP) and lymphoma-specific survival (LSS). A total of 35 cases were enrolled. At diagnosis, all dogs showed generalized lymphadenopathy. One-third was systemically unwell. All dogs had stage V disease; one-third also had extranodal involvement. The LN population was mainly composed of medium-sized CD21+ cells with scant resident normal lymphocytes. Histology revealed diffuse LN involvement, referring to "late-stage" MZL. Median TTP and LSS were 149 and 259 days, respectively. Increased LDH activity and substage b were significantly associated with a shorter LSS. Dogs with nMZL may show generalized lymphadenopathy and an advanced disease stage. Overall, the outcome is poor, despite the "indolent" designation. The best treatment option still needs to be defined. © 2017 John Wiley & Sons Ltd.

    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 Primary non-Hodgkin′s lymphoma of the common bile duct is extremely rare. We present a case with history of inflammatory bowel disease and clinical manifestations of obstructive jaundice. Abdominal magnetic resonance imaging with magnetic resonance cholangiopancreatography (MRCP was done and demonstrated tight stricture at the middle part of common bile duct, and radiological findings were supportive of extra-hepatic cholangiocarcinoma. Whipple′s procedure was performed and the case was histopathologically proven to be non-Hodgkin′s lymphoma of follicular subtype involving the common bile duct. Lymphoma of the hepatobiliary system is usually present as secondary manifestation of systemic malignant lymphoma. However, primary malignant lymphomas arising from the hepatobiliary tree are extremely rare. The radiological appearance of common bile duct lymphoma is very similar to cholangiocarcinoma, making preoperative diagnosis very difficult, as in our present case. We also compare the imaging findings of our case to those seen in reported cases of follicular lymphoma of the common bile duct.

    March 2003 and July 2005. Of these 22 cases, 12 were Hodgkin's and 10 were non-Hodgkin's. RESULTS: Overall, mediastinal lymphadenomegaly was the most frequent finding (59%, with predominance in the Hodgkin's subgroup (75%, followed by hepatosplenomegaly (50% and cervical and retroperitoneal lymphadenomegaly (27.3%. The Hodgkin's subgroup presented a prevalence of lymphadenopathy, in many lymph node chains, followed by hepatosplenomegaly (50%. One case was found with unilateral tonsillar mass, pulmonary ground-glass opacities, and renal nodules. In the non-Hodgkin's subgroup, the disease was predominantly extranodal, characterized by hepatosplenomegaly (50%, thickening of the intestinal wall (40%, pleural effusion (30%, pulmonary nodule (20%, ascites (10%, pericardial effusion (10% and mixed bone lesions (10%. CONCLUSION: Computed tomography is an extremely useful method for detection, staging and follow-up of lymphomas, with alert findings like mediastinal lymphadenopathy, hepatosplenomegaly, unilateral tonsillar mass and thickening of intestinal wall.

    Follicular lymphoma (FL) is the most common indolent non-hodgkin lymphoma. Most patients with FL are diagnosed with advanced disease and are considered incurable. The classical prognostic index in FL is the FL international prognostic index (FLIPI). The management of FL is mainly determined by histologic grading, clinical stage, and tumor burden. For patients with stage I and II disease, an involved-site radiation therapy (ISRT) is recommended and may be potentially curative approach with 60% to 80% of 10-year overall survival (OS) rates, while patients with stage III and IV should be treated with systemic therapy. The watchful waiting is still an option for patients without symptoms or/and low tumor burden. Induction of immuno-chemotherapy combined with consolidation of rituximab maintenance (MR) is standard care for patients with symptomatic disease or with high tumor burden when treatment indicated. The major indication for systemic therapy is including candidate for clinical trials, threatened end organ function, cytopenia secondary to lymphoma bulky disease and steady progress etc. at present time. Routine baseline and regular hepatitis B surface antigen (HBsAg) and hepatitis B core antibody (HBcAb) testing is strongly recommended for all patients before the initiation of immuno-chemotherapy in order to minimize the risk of hepatitis B virus (HBV) reactivation which has been observed approximately 20% to 50% of patients with positive HBsAg and 3% to 45% of patients with positive HBcAb. Prophylactic antiviral treatment in patients who are HBsAg-positive or HBcAb-positive is indicated before immuno-chemotherapy. The management for elderly patients should be carefully selected to avoid overtreatment and severe toxicities. Individualized dose adjustment for chemotherapy and an adequate supportive treatment are essential for this special population. Novel agents such as lenalidomide, ibrutinib and idelalisib are promising. In conclusion, individualized management

    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

    2012-01-01

    Aim: To determine the specific imaging criteria on contrast-enhanced multidetector computed tomography (MDCT) for differentiating between tuberculosis and lymphoma in mediastinal lymph nodes. Materials and methods: The anatomical distribution and enhancement patterns of mediastinal lymph nodes on contrast-enhanced MDCT were reviewed in 37 patients with tuberculosis and 54 patients with lymphoma. Of the patients with lymphoma, 18 had Hodgkin's disease and 36 had non-Hodgkin's lymphoma. Results: Region 10R was involved more often in tuberculosis than in Hodgkin's disease and non-Hodgkin's lymphoma. Region 6 had a higher tendency to be affected in Hodgkin's disease and non-Hodgkin's lymphoma compared with tuberculosis. Tuberculosis showed peripheral enhancement in 78% of cases, frequently with a multilocular appearance, compared to Hodgkin's disease and non-Hodgkin's lymphoma, which showed peripheral enhancement in only 6 and 3% of cases, respectively. Homogeneous enhancement was more commonly seen in lymphoma (83% for Hodgkin's disease, and 83% for non-Hodgkin's lymphoma) than in tuberculosis (8%). In the determination of tuberculosis, results showed that when a peripheral enhancement pattern was seen, sensitivity was 78%, specificity was 96%, and accuracy was 89%. In the determination of lymphoma, results showed that when a homogeneous enhancement pattern was seen, sensitivity was 83%, specificity was 92%, and accuracy was 87%. Conclusion: The findings of the present study indicate that specific anatomical distribution and enhancement patterns of lymphadenopathy shown on contrast-enhanced MDCT can be useful in differentiating tuberculosis from lymphoma of mediastinal lymph nodes.

    Extranodal marginal-zone lymphoma of mucosa-associated lymphoid tissue of the stomach (gastric MALT lymphoma) is derived from memory B cells of the marginal zone. Normal memory B cells do not express markers of germinal-center B cells, such as E2A (immunoglobulin enhancer-binding factor E12/E47), B-cell chronic lymphocytic leukemia/lymphoma 6 (BCL6), or activation-induced cytidine deaminase (AID). E2A is a transcription factor that induces somatic hypermutations and blocks plasma cell differentiation. In 50 stage-I(E)/II(E1) gastric MALT lymphomas, we confirmed that all cases were BCL6(-)/AID(-), but a subset (50%, 25/50) was E2A(+). As E2A(-) and E2A(+) gastric MALT lymphomas had similar numbers of somatic hypermutations without intraclonal variations, which implied an origin from memory B cells, the expression of E2A was best regarded as a marker of aberrant follicular differentiation. Although the status of somatic hypermutation was not affected by E2A, E2A(+) gastric MALT lymphoma showed less plasmacytoid infiltrates and higher expressions of miRNA-223, a microRNA associated with memory B cells. Clinically, E2A(+) gastric MALT lymphomas were more likely to spread to perigastric lymph nodes and were less responsive to Helicobacter eradication therapy than were E2A(-) gastric MALT lymphomas. Taken together, aberrant E2A expression is a diagnostic feature of a subtype of gastric MALT lymphoma with weaker plasmacytoid infiltrates and stronger miR-223 expression. A prospective study would be necessary to verify the association between E2A expression and a poor response to Helicobacter eradication therapy.

    Certain patients with lymphoma may harbor mutations in perforin 1 (PRF1), unc-13 homolog D (UNC13D), syntaxin 11 (STX11), STXBP2 (syntaxin binding protein 2) or SH2 domain containing 1A (SH2D1A), which causes functional defects of cytotoxic lymphocytes. Data regarding the association between genetic defects and the development of lymphoma in Chinese patients are limited to date. In the present study, 90 patients with lymphoma were analyzed for UNC13D, PRF1, STXBP2, STX11, SH2D1A and X-linked ...

    Aim: Comparison of diagnostic efficiency of FDG-PET and CT regarding localisation, histology, size and FDG-uptake of a lesion. Methods: CT- and FDG-PET studies of 27 patients with histologically confirmed malignant lymphoma as primary disease or relapse were evaluated retrospectively. In CT lesions with a diameter (D CT )>15 mm were regarded as positive. Focal accumulations of FDG, not explained by physiological metabolism, found by visual interpretation in iterative reconstructed, PET-scans, were quantified for diameter (D PET ) and corrected standardized uptake value (SUV), corrected for partial-volume-effect. Lesions were classified depending on histology and lesion quality (lymph nodes, bulks, extranodal lesions). Results: CT detected 78 lesions in 26 patients, all confirmed by FDG-PET. PET localized 18 additional lesions (+23%); in high grade NHL +25%. Both methods were equally efficient in cevical lymph nodes and lung lesions, in all other regions of lymphatic nodules and in case of liver and spleen lesions PET localized more lesions. SUV was significantly higher in high-grade NHL (19.0) than in low-grade NHL and Hodgkin's disease (10.6 resp. 11.1). D CT and D PET correlated significantly (r=0.75). Conclusion: Diagnostic efficiency of FDG-PET is equivalent or superior to CT in staging of malignant lymphoma before therapy. Qualitative interpretation seems sufficient for staging, quantitative analysis may add information about malignancy grade in NHL. (orig.) [de

    Cutaneous T cell lymphomas (CTCL) represent rare extranodal non-Hodgkin's lymphomas, which are characterised by pleomorphic skin lesions and distinct T-cell markers. CTCL is a relatively benign disease in its early stages, but survival rates decrease significantly with progression. Histone deacetylase inhibitors (HDACi) have recently emerged as a new class of targeted anticancer therapies for CTCL, which have been shown to induce growth inhibition, terminal differentiation and apoptosis in various cancers in vitro and in vivo. In addition to the intrinsic anticancer properties of HDACi, recent studies have demonstrated its ability to synergise with phototherapy. In particular, we examine the therapeutic potential of HDACi in combination with ultraviolet A (UV-A) phototherapy, employing a halogenated DNA minor groove binding ligand called UVASens as a photosensitiser. In vitro studies have demonstrated that UVASens is approximately 1000-fold more potent than current psoralens. The extreme photopotency of UVASens allows the use of lower radiation doses minimising the carcinogenic risks associated with the long-term use of phototherapy. Considering, previous findings using the photosensitiser UVASens and potential synergy of HDACi with phototherapy, it was hypothesised that HDACi will augment photochemotherapy-induced cytotoxicity in CTCL MyLa cells. The findings indicated that combinations of UVASens/UV-A photochemotherapy and HDACi significantly decreased cell viability and increased apoptosis and DNA double-strand breaks in MyLa cells.

    Full Text Available Nathan M Denlinger, Narendranath Epperla, Basem M William Department of Internal Medicine, The Ohio State University Comprehensive Cancer Center (OSUCCC-James, The Ohio State University, Columbus, OH, USA Abstract: Marginal zone lymphomas (MZLs consist of a diverse family of malignancies, which are derived from B-cells. The disease subtypes are recognized extranodal, nodal, and splenic MZLs. The disease characteristics, clinical course, and treatment vary considerably based on the site of involvement. In 2017, the US Food and Drug Administration approved ibrutinib, a first in class Bruton’s tyrosine kinase inhibitor that revolutionized the care of chronic lymphocytic leukemia patients; for, the treatment of relapsed/refractory MZL based on pivotal open-label Phase II trial demonstrated an overall response rate of 48%, with a complete response rate of 3%, median progression-free survival of 14.2 months, and median overall survival not yet reached at a median follow-up of 19.4 months. In this review, we aim to summarize the current conundrums in the management of MZL and the evolving role of ibrutinib in the treatment of MZL.

    The last 25 years have seen major changes in the imaging investigation and subsequent management of patients with Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL); accurate staging is vital for prognostication and treatment in both, and particularly in HD. The choice of imaging modality for staging depends on its accuracy, impact on clinical decision-making, and availability. Modern CT scanners fulfil most of the desired criteria. The advent of CT scanning, along with the development of ever more effective chemotherapeutic regimens, has resulted in the virtual demise of bipedal lymphangiography (LAG) as a staging tool in patients with lymphoma. It has rendered superfluous a battery of other tests that were in routine use. This contribution reviews the evidence for the use of CT in preference to LAG. CT accurately depicts nodal enlargement above and below the diaphragm, has variable sensitivity for intra-abdominal visceral involvement and is generally outstanding in depicting the extent of disease, especially extranodal extension. Despite the advances in CT technology, there are still areas where CT performs less well (e.g. disease in normal-sized lymph nodes, splenic and bone marrow infiltration). The influence of technical factors, such as the use of intravenous contrast medium, is discussed. In some instances, CT is not the imaging modality of choice and the place of newer techniques such as MRI and endoscopic ultrasound will be reviewed. (orig.)

    Warthin-Finkeldey type giant cells were first described in autopsies performed on young children who died during the highly lethal measles epidemic in Palermo during the winter of 1908. The cells had 8-15 nuclei without identifiable cytoplasm within the germinal centers of lymphoid organs resembling megakaryocytes. We describe a case of Hashimoto thyroiditis with an enlarging substernal throid mass. The resection specimen contained many Warthin-Finkeldey-Like Cells (WFLC) in an extranodal marginal zone lymphoma (MALT type) with focal transformation to diffuse large B-cell lymphoma. The WFLC showed nuclear features similar to those of neighboring follicular dendritic cells (FDCs), favoring the hypothesis that these cells might be the product of fusion of FDCs. This is supported by immunostaining results and the occurrence of similar cells in follicular dendritic cell sarcomas and in "dysplastic" FDCs in hyaline vascular type Castleman disease, a possible precursor of follicular dendritic cell tumors.

    Full Text Available El linfoma no Hodgkin primario de la mama es una entidad poco frecuente en pediatría y representa el 0,4 al 0,5 % de todos los tumores mamarios malignos. Debido a que carecen de características propias, tanto clínicas, citológicas como ecográficas, resulta muy difícil establecer el diagnóstico preoperatorio. Se presenta el caso de un linfoma no Hodgkin primario de la mama en una paciente de 3 años que llegó en estadio avanzado de la enfermedad, y se subraya la importancia del tratamiento en un equipo multidisciplinario.The primary non-Hodgkin breast lymphoma is a not frequent entity in children and account for the 0,4 to 0,5% of the malignant breast tumors. Due to they lack of own clinical, cytological and echography features, it is very difficult to made the preoperative diagnosis. This is the case of a primary non-Hodgkin breast lymphoma in a patient aged 3 with an advanced stage of disease, emphasizing the significance of treatment in a multidisciplinary staff.
