[PMID: 38846862 PMCID: PMC11152792 DOI: 10.1097/ms9.0000000000002051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Accepted: 03/28/2024] [Indexed: 06/09/2024] Open
Abstract
Introduction and importance Primary bladder lymphoma accounts for a mere fraction of vesical tumours and extranodal lymphomas, which mostly affect women. IGH-BCL2 translocation, which occurs in 80-100% of Western follicular variants but only 60% in Asian communities, must be studied to determine its effects on prognosis and treatment. This study analyses and compares relevant literature and data for the authors' case report. Case presentation The authors report a 69-year-old Caucasian female with one gross haematuria episode and no smoking history. Computed tomography (CT) showed a bilateral massive intraluminal mass left ureterovesical junction, hydronephrosis, and hydroureter. Clinical discussion Following the removal of a massive transurethral urinary bladder tumour, histological examination revealed lymphoma cells positive for IRTA and LMO2 but negative for IGH-BCL2. After these analyses, the patient received 3 weeks of 30 Gy/15 f IMRT/IGRT. Comparisons were made to previous case reports' histopathology. Conclusion The current case report emphasizes the rarity of primary bladder lymphoma and the absence of the IGH-BCL2 fusion gene. Following the successful administration of 30 Gy of radiation therapy, the patient's prognosis improved. The report emphasizes clinical vigilance and timely management while also urging further investigation.

Abstract
INTRODUCTION Mucosa Associated Lymphoid Tissue (MALT) lymphoma is the third most common subgroup of Non-Hodgkin's lymphoma and is the most common type of primary extranodal lymphoma. They are rarely found in the nasopharyngeal region and their mean age at presentation is the sixth decade of life. MATERIALS AND METHODS We present the clinical, pathological, treatment and 5-year follow-up data of 5 cases of nasopharyngeal MALT lymphoma treated with definitive radiotherapy at our hospital, between 2009 and 2011. RESULTS The average age of diagnosis was 27 years which is more than a decade earlier than what has been reported previously. Clinical symptoms included nasal obstruction, tinnitus and hearing loss. All five patients had locoregional disease. They were treated by definitive radiotherapy to a dose between 30 to 40 Gy. At 5 years of follow-up, 4 patients were in complete remission while one had disease relapse. CONCLUSION The younger age of presentation compared to older reports in this rare subsite was an interesting finding in our study. The authors speculate that rising levels of particulate air pollution may have played a part in the etiology in this younger population. Our series shows that despite the younger age, the disease displays an indolent course and responds well to radiotherapy alone as the primary treatment. Recurrence or disseminated disease is also highly treatable with systemic chemotherapy.

Abstract
Thyroid eye disease (TED), also called Graves orbitopathy (GO), is the most common diagnosis of orbital tissue inflammation. It is typically associated with the onset of hyperthyroidism, an autoimmune response to excess amounts of thyroid hormone. However, a visible and palpable lump, strictly unilateral or gross asymmetric eye involvement, non-axial (eccentric) proptosis, a lack of lid retraction or lid lag on downward gaze, or weakened muscle function (suggestive of tendon involvement) are the key features of non-TED mediated ocular involvement, as was found in the case we report here. Orbital lymphoma should always be suspected and excluded in all cases of orbital inflammation. Our patient was diagnosed with mucosa-associated lymphoid tissue (MALT) lymphoma at 27 years of age, two years after the diagnosis of euthyroid ophthalmopathy. This case highlights the need to include space-occupying lesions in the differential diagnosis of proptosis and gaze restrictions, even in younger patients.

Abstract
Introducción y objetivo: Los linfomas de la glándula parótida son una entidad infrecuente. Presentamos un caso clínico de linfoma tipo MALT de parótida, describiendo sus métodos diagnósticos y de tratamiento más empleados. Descripción: Mujer de 69 años con tumoración asintomática en cola de parótida y visión de estructuras nodulares en imagen de TC y RM con PAAF negativa. Se realiza parotidectomía total hallando el diagnóstico de linfoma MALT de la zona marginal. Se completa tratamiento mediante esquema R-CHOP durante 4 meses, sin signos de recidiva al año. Discusión: El linfoma tipo MALT es un tipo de LNH relacionado principalmente con inflamación autoinmune crónica en el caso de aparición sobre glándulas salivales. Se presenta como una tumoración asintomática e inespecífica de crecimiento lento y se diagnostica mediante TC o RM en su mayoría de casos. El tratamiento se realiza mediante parotidectomía asociado a quimioterapia y/o radioterapia, con una tasa de supervivencia mayor al 80% en 5 años. Conclusiones: Los linfomas de glándulas salivales son poco habituales y ocasionalmente se diagnostican de manera inadecuada debido a su comportamiento benigno que mimetiza a tumores más familiares del área parotídea. Su sospecha y distinción son esenciales y no deben olvidarse en nuestro diagnóstico diferencial de masas parotídeas.

Expression of PD-L1 and YWHAZ in Patients with Diffuse Large B Cell Lymphoma: A Possible Association with the Prognosis of Lymphoma. J Immunol Res 2022; 2022:5633096. [PMID: 36213322 PMCID: PMC9534712 DOI: 10.1155/2022/5633096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Revised: 08/26/2022] [Accepted: 09/09/2022] [Indexed: 12/24/2022] Open
Abstract
Diffuse large B cell lymphoma (DLBCL) is the most common pathological subtype of non-Hodgkin lymphoma (NHL) and is the most common type of adult lymphoma. Due to the poor prognosis of relapsed/refractory DLBCL, new drug targets and therapeutic methods are urgently needed. We investigated the expression of programmed death ligand 1 (PD-L1) and 3-monooxygenase/tryptophan 5-monooxygenase activating protein zeta (14-3-3ζ or YWHAZ) in patients with DLBCL. The purpose was to verify the expression levels of YWHAZ and PD-L1 and their relationships with the prognosis of DLBCL and to lay a foundation for further study on the role of YWHAZ and PD-L1 in DLBCL. Immunohistochemistry was used in 140 patients with DLBCL to test protein expression levels of YWHAZ and PD-L1. All patients were followed up in the hospital or by telephone or via WeChat. The positive expression rate of YWHAZ was 62.14% (87/140). The expression was negatively correlated with the positive expression of BAD (r = −0.177, P = 0.036) and positively correlated with the positive expression of BCL-2 (r = 0.180, P = 0.033). When the cut-off value for PD-L1 was established at 5%, 10%, 15%, and 20%, the corresponding positive expression rates of PD-L1 were 79.66% (94/118), 51.69% (61/118), 40.68% (48/118), and 36.44% (43/118). YWHAZ significantly affected the OS of DLBCL (P ≤ 0.001). The prognosis of the patients was related to the positive expression of PD-L1 when the cut-off value of PD-L1 was 5% (P = 0.033). However, positive expression of PD-L1 was not associated with the prognosis when the cut-off values of PD-L1 were 10% (P = 0.404), 15% (P = 0.208), and 20% (P = 0.408). The positive expression of YWHAZ (hazard ratio 6.215; 95% confidence interval 3.214-12.017; P < 0.05) was an independent adverse prognostic factor for OS. YWHAZ may be an important oncogene in the occurrence and development of DLBCL and may be used as a therapeutic target. PD-L1 may be an oncogene or tumor suppressor gene in the occurrence and development of DLBCL. Different cut-off values of PD-L1 may affect the prognosis of DLBCL.

Abstract
Statistical reports on non-Hodgkin's lymphoma (NHL) of the head and neck combining clinical medicine with pathology are rare. To provide a basis for prognosis prediction and individualized treatment, we will investigate the clinicopathologic characteristics and prognosis of lymphoma in the head and neck region. Four hundred sixty-one patients with NHL in the head and neck region diagnosed through histological biopsy were retrospectively analyzed. Fluorescence in situ hybridization (FISH) and immunohistochemistry (IHC) were performed in all cases to evaluate the genetic status and protein expression levels. Patients were followed up by telephone. The prevalence rate of primary extranodal NHL (PENHL) in the head and neck region was 44.62% (166/372). The incidence of extranodal lymphoma accounted for 36.66% (169/461) of all head and neck lymphomas. Among the cases of PENHL of the head and neck, diffuse large B-cell lymphoma (DLBCL) (60/76, 78.95%) and extranodal NK/T-cell lymphoma, nasal type (ENKTCL) (21/24, 87.5%) were the most common subtypes originating from B-cell lymphoma (BCL) and T-cell lymphoma (TCL), respectively. The most common sites of nodal and extranodal onset were neck lymph nodes and the gastrointestinal tract, respectively. The most common and primary locations of BCL and TCL were the tonsils and nasal cavity, respectively. The 3-year survival rates of PENHL, ENKTCL, and DLBCL of the head and neck were 42%, 28.57%, and 41.67%, respectively, and the 5-year survival rates were 24%, 19.05%, and 20%, respectively. Survival analysis showed that male sex was a risk factor (HR = 5.421; 95% CI, 1.164-25.267; p < 0.05) and that comprehensive treatment was a protective factor (HR = 0.117; 95% CI, 0.025-0.545; p < 0.05) against extranodal DLBCL in the head and neck region. Bone marrow involvement was a risk factor for PENHL of the head and neck (HR = 5.072; 95% CI, 1.17-21.991; p < 0.05). The purpose of this review is to show that PENHL of the head and neck with high incidence deserves more attention, and a model of multidisciplinary diagnosis and treatment should be adopted.

Abstract
ABSTRACT Solitary non-Hodgkin lymphoma of the trachea is extremely rare. Herein, we reported a case of solitary laryngotracheal lymphoma in a 55-year-old man. He complained of cough, tachypnea, and dyspnea. 18F-FDG PET/CT showed a hypermetabolic lesion in the subglottic larynx and upper cervical trachea. The subsequent histology and immunohistochemistry of the laryngotracheal lesion tissue confirmed the diagnosis of non-Hodgkin lymphoma (mucosa-associated lymphatic tissue lymphoma).

Abstract
OBJECTIVE To analyze the clinicopathological characteristics of mucosa associated lymphoid tissue (MALT) lymphoma secondary to Sjögren' s syndrome (SS) (SS-MALT lymphoma) in salivary gland and to explore the value of the combined application of histopathological morphology, protein expression and molecular phenotype in pathological diagnosis and prognostic evaluation of SS-MALT lymphoma. METHODS Sixteen patients with SS-MALT lymphoma were collected from 260 patients who were diagnosed with SS in Peking University School and Hospital of Stomatology from January 1997 to December 2016. Twelve patients with non-MALT lymphoma secondary to SS (non-SS-MALT lymphoma) in salivary gland were selected as controls. The clinical data of the patients were retrospectively reviewed and analyzed. All the patients were followed up until December 20, 2019. Hematoxylin-eosin staining, immunohistochemistry, polymerase chain reaction (PCR) and fluorescence in situ hybridization (FISH) techniques were used to observe the histologic characteristics and to detect the manifestations of light chain restrictive expression, immunoglobulin (Ig) gene clonal rearrangement, chromosome translocation and gene abnormality, so as to evaluate their values in pathological diagnosis and prognostic evaluation. RESULTS The malignant transformation rate of SS to MALT lymphoma was about 6.15%, ranged from 3 to 240 months, during which 2 patients died due to high-level deterioration. Microscopically, the acini of the glandular tissue were atrophied and destroyed. The tumor cells dominated by central cell-like lymphocytes grew diffusely, destroying the epithelial islands. All SS-MALT lymphoma cases were positive in CD20 and Pax5. Half of them had the Ki-67 proliferation index of 10% or less, and half greater than 10%. 93.75% cases expressed AE1/AE3 protein, which showed the residual glandular epithelium. All the tumor cells were negative in CD3ε, and the plasma cells were detected by CD138 antigen. The light chain restrictive expression of κ and λ was 37.5% in SS-MALT lymphoma group. The positive detection rates of immunoglobulin heavy chain (IgH)-FR1, IgH-FR2, IgH-FR3, immunoglobulin kappa chain (IgK)-A, and IgK-B in SS-MALT lymphoma group were 33.3%, 53.3%, 33.3%, 20.0%, and 26.7%, respectively, and 93.3% when together used with IgH and IgK. The positive rates of the MALT1, IGH and BCL6 genes with dual color break-apart probes were 36.4%, 27.3% and 27.3%, and the detection rate of chromosome translocation and gene abnormality by applying the three probes was 72.7%. CONCLUSION There are no specific histological characteristics and protein phenotypes in the histologic diagnosis of SS-MALT lymphoma in salivary gland. The combined application of histopathological manifestations, immunohistochemistry, PCR and FISH techniques helps the accurate pathologic diagnosis of the disease. Although SS-MALT lymphoma is considered as an indolent lymphoma with a relatively favorable prognosis, the regular return visit and long-term follow-up should be conducted to detect the clues of recurrence and advanced deterioration.

Abstract
Worldwide, infectious agents currently contribute to an estimated 15% of new cancer cases. Most of these (92%, or 2 million new cancer cases) are attributable to 4 infectious agents: Helicobacter pylori, human papillomavirus, and hepatitis B and C viruses. A better understanding of how infectious agents relate to the US cancer burden may assist new diagnostic and treatment efforts. We review US-specific crude mortality rates from infection-associated cancers and describe temporal and spatial trends since 1999. We review the US-specific evidence for infection-cancer associations by reporting available estimates for attributable fractions for the infection-cancer associations. Death due to cancers with established infectious associations varies geographically, but estimates for the US attributable fraction are limited to a few observational studies. To describe the burden of infection-associated cancer in the United States, additional observational studies are necessary to estimate the prevalence of infection nationally and within subpopulations. As infectious associations emerge to explain cancer etiologies, new opportunities and challenges to reducing the burden arise. Improved estimates for the United States would help target interventions to higher-risk subpopulations.

Abstract
INTRODUCTION Primary bladder mucosa-associated lymphoid tissue (MALT) lymphoma is a rare tumor. To date, the PubMed database contains only 39 English articles covering 63 cases of primary bladder MALT lymphoma. Herein, we report a case of this disease and review the current literature. PATIENT CONCERNS A 77-year-old woman presented with frequent urination, urinary urgency, and dysuria for 3 years. In the past 3 years, the patient's symptoms recurred and progressively worsened, and she was admitted to the hospital. DIAGNOSIS A histopathological examination revealed the bladder mass as a tumor with high proliferation of atypical B-lymphocytes. Immunohistochemistry showed positive results for CD20, PAX-5, Ki-67, BCL-2, and CD21 and negative results for CD10, MUM1, TDT, and cyclin D1. These data supported the diagnosis of primary bladder MALT lymphoma. INTERVENTIONS A transurethral resection of bladder tumor was performed to treat the disease. OUTCOMES The patient was alive and healthy at the 15-month follow-up. CONCLUSION Primary bladder MALT lymphoma is a rare disease and can be easily missed or misdiagnosed before achieving a histological confirmation. Surgery may be the best choice for both diagnosis and treatment.

Abstract
Background Helicobacter pylori (HP) has been considered to be one of the primary causes of gastric mucosa-associated lymphoid tissue (MALT) lymphoma since 1993. Low-grade gastric MALT lymphoma with HP is widely treated with HP eradication therapy, according to each specific clinical situation. However, several studies and guidelines indicate that the modified HP eradication therapy is also valid for HP-negative gastric MALT lymphoma. The aim of this study was to perform a meta-analysis of the clinical efficacy of the modified HP eradication therapy for gastric MALT lymphoma without HP. Methods We searched studies that reported the response rate of the modified HP eradication therapy regimen for gastric MALT lymphoma without HP by using PubMed, Medline, and Ebsco from January 1971 until February 2019. All statistical analyses were carried out using R 3.5.3 (Mathsoft Company, Cambridge, MA, USA). The pooled response rate was expressed as a decimal. The heterogeneity test was performed using the I-squared (I2) statistic. Results A total of 14 studies were selected with a total of 148 patients with HP-negative gastric MALT lymphoma. The overall pooled response rate was 0.38 (95% confidence interval [CI]: 0.29–0.47). The combined estimate is I2 = 57% (P < 0.01). The study subjects were categorized by factors (area of patients). The pooled response rate of the sub-groups (Korea, Japan, China, and Western countries) was 0.63 (95% CI: 0.50–0.76), 0.16 (95% CI: 0.05–0.30), 0.38 (95% CI: 0.20–0.55), and 0.57 (95% CI: 0.08–1.00). The response rate showed that the modified HP eradication therapy was effective for patients with HP-negative gastric MALT lymphoma, especially in Korea and Western countries. Conclusion Therefore, the modified HP eradication therapy can be considered an optional therapy for patients with low-grade HP-negative gastric MALT lymphoma. However, several limitations were revealed in the meta-analysis. Further systematic reviews and research are required.

Abstract
Lymphomas of the salivary glands are a rare entity with a rare incidence. They are more commonly found on the parotid gland, followed by the submandibular and sublingual glands. The majority of parotid lymphomas are non-Hodgkin’s lymphomas and are considered to be derived from mucosal-associated lymphoid tissue (MALT). Reports of these cases are scarce and often misdiagnosed since: their manifestation is relatively benign, they have a localized behavior, a slow growth and the evolution takes several years.
Key words: Type MALT lymphoma; parotid gland tumor

Abstract
Lymphomas constitute the third most common neoplasm in head and neck region arising from the lymphoreticular system. Malignant lymphomas are divided into Hodgkin's disease and non-Hodgkin's lymphoma (NHL). NHL comprises approximately 5% of head and neck malignancies and displays a wide range of appearances comparable with Hodgkin's disease. Hodgkin's and non-Hodgkin's lymphomas are seen in the head and neck region, but extranodal disease, with or without lymph node involvement, is more common among NHL patients. Extranodal involvement includes the areas such as Waldeyer's ring (i.e., the tonsils, pharynx, and base of the tongue), salivary glands, orbit, paranasal sinuses, and thyroid glands. There are several classification systems for categorizing NHL out of which WHO classification for lymphoid neoplasms is mostly followed. This review describes the pathogenesis of NHL and explains some of the important NHL (Marginal zone B-cell Lymphoma, follicular lymphoma, mantle cell lymphoma).

Abstract
PURPOSE We performed an epidemiological study of orbital lymphoma in the United States to determine how histological subtypes confer differing prognosis, and understand other factors associated with survival. METHODS All patients in the Surveillance, Epidemiology and End Results database diagnosed with a histologically confirmed orbital lymphoma between 1973 and 2014 were included. Exclusion criteria included diagnosis at autopsy and the presence of other malignancies. Measures included patient demographic information, histological subtype and treatment modalities. Outcomes included overall and disease specific survival. RESULTS Of the 1504 cases identified, 702 were male (46.7%, mean age: 64.4 years, standard deviation [SD]: 15.3) and 802 were female (53.3%, mean age: 67.5 years, SD: 14.3). Mucosal associated lymphoid tissue (MALT) (49.5%) and diffuse large B cell lymphoma (DLBCL) (19.5%) were the two most common histologic subtypes. MALT lymphoma conferred the best prognosis (10-year cancer specific survival [CSS] 90.2%, 95% Confidence Interval [CI] 87.4% - 93.1%) and DLBCL conferred the worst prognosis (10-year CSS 68.6%, 95% CI 62.5% - 75.3%) (p < .001, log-rank test). Older age (Hazard Ratio [HR]: 3.71, 95% Confidence Interval [CI]: 2.94-4.66, p < .001), male sex (HR: 1.22, 95% CI: 1.039-1.441, p = .015), no radiation (HR: 1.72, 95% CI: 1.46-2.02, p < .001) and DLBCL histology were significant predictors of worse overall survival. CONCLUSIONS DLBCL histology confers the worst outcomes whereas MALT lymphoma confers the best outcome in orbital lymphoma. Age, gender, and radiation treatment also influence survival. These epidemiological results can be used clinically to communicate outcomes on the basis of patient characteristics and disease histology.

Abstract
Mucosa-associated lymphoid tissue (MALT) lymphoma with t(11;18)(q21;q21), resulting in an API2-MALT1 fusion transcript, is reported to rarely transform into aggressive lymphoma. Here, we report the clinical course of a patient who experienced histologic transformation after 20 years' disease history of t(11;18)-positive MALT lymphoma. The patient suddenly developed a large intrapelvic mass and ascites with a rapid increase in lactate dehydrogenase. Cytology of the ascites detected large abnormal cells, and flow cytometric analysis revealed that the cells were positive for cytoplasmic CD3, CD4, and CD38, and partially positive for CD7, but negative for CD19 and CD20. Antigen receptor gene rearrangement analysis and in situ hybridization of the immunoglobulin light chains confirmed that the tumor cells were of B-cell lineage. Chromosomal analysis showed complex karyotypes with intraclonal variation, and in addition to t(11;18), t(8;14) and heterozygous loss of the TP53 were demonstrated. Although histological and phenotypic features were significantly altered from the original MALT lymphoma, the presence of t(11;18) led us to the diagnosis of histologic transformation of MALT lymphoma. Although transformation of t(11;18)-positive MALT lymphoma into aggressive lymphoma is extremely rare, it may occur, probably with additional genetic abnormalities such as cMYC rearrangement and/or the loss of TP53.

Abstract
Primary pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is extremely rare. MALT lymphoma patients usually show no clinical symptoms or physical signs. Chest radiograph or computed tomography (CT) may confuse MALT lymphoma with other pulmonary diseases, which would lead to misdiagnosis or a delayed diagnosis. In the present study, a 33-year-old male patient had cough and fever. Chest CT showed consolidation on both sides. Those clinical symptoms disappeared after he had been misdiagnosed and treated for community-acquired pneumonia for three weeks. However, further chest CT still showed the consolidation without any change. Then an ultrasonic guided transthoracic needle biopsy was performed. Morphological changes indicated the diagnosis of extranodal marginal Zone B cell lymphoma of MALT. The patient was then treated with chemotherapy and rituximab. After this line of treatment, the consolidation decreased.

Abstract
Objective To evaluate the performance of probe-based confocal laser endomicroscopy (pCLE) in diagnosis of gastric lesions. Methods An outpatient department- (OPD-) based retrospective study was conducted for patients with suspected upper gastrointestinal (GI) tract lesions who underwent pCLE between 2014 and 2016 at a tertiary hospital in China. Final diagnosis was based on the histopathological reports. CLE reports were compared to histopathological reports to evaluate the diagnostic ability, including sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy. Results 322 of 380 patients were diagnosed with gastric lesions via pCLE, including inflammation and benign ulcers (n = 110), atrophy and intestinal metaplasia (n = 152), intraepithelial neoplasia (n = 27), adenocarcinoma (n = 27), and lymphoma (n = 6). In total, the diagnostic ability of CLE in evaluation of gastric lesions showed sensitivity 72.4% (95% confidence interval (CI): 67.1-77.2%); specificity 93.1% (95% CI: 5.6-8.4%); PPV 72.4% (95% CI: 67.1-77.2%); NPV 93.1% (95% CI: 5.6-8.4%); and accuracy 88.9% (95% CI: 87.3-90.4%), respectively. We further observed the capability of pCLE in diagnosing six gastric lymphoma showing those affected mucosa densely infiltrated with identical and round-shaped abnormal cells. Immunohistochemistry analysis confirmed one patient with diffuse large B-cell non-Hodgkin's lymphoma (DLBCL) and five with mucosa-associated lymphoid tissue (MALT) lymphoma. Conclusion pCLE is an accurate tool for the detection of gastric lesions and shows optimal values of sensitivity and negative predictivity. Moreover, combining pCLE with white light endoscopy (WLE) may be a promising adjunct to conventional biopsy sampling in evaluating GI tract with suspected lymphoma.

Abstract
Mucosa-associated lymphoid tissue (MALT) is vital for host immunological surveillance against pathogens. MALT lymphoma, also known as extranodal marginal zone B cell lymphoma, is a non-Hodgkin's lymphoma subtype that predominantly arises in the gastrointestinal tract. Chronic Helicobacter pylori (H. pylori) infection is a common cause of gastric MALT lymphoma, although other infections are reported in association with extragastric MALT lymphomas. To our knowledge, here we report the first case of synchronous MALT lymphomas of the colon and stomach in the presence of Strongyloides stercoralis and H. pylori infections that resolved after eradication of both organisms.

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.

Abstract
Nodular pulmonary amyloidosis is a very rare form of localized amyloidosis involving the lung, with very little known about its nature. It is usually associated with indolent B cell lymphoproliferative disorder and also connective tissue disorders. No definite treatment guideline exists. Many patients respond to chemotherapy with low risk of progression and a 'wait and watch' strategy is also considered a valid treatment option. In this report the authors present a case of nodular pulmonary amyloidosis with pulmonary mucosa associated lymphoid tissue (MALT) lymphoma that presented with features of metastatic malignant disease and after definitive diagnosis decided not to undergo treatment.

Abstract
RATIONALE Primary hepatic mucosa-associated lymphoid tissue (MALT) lymphoma is an extremely rare disease. To the best of our knowledge, only 67 cases had been reported in 39 English literatures to date. The aim of this study was to add a new case of this disease to the literature and to review the current literature. PATIENT CONCERNS A 50-year-old man was incidentally identified with a solitary mass of 5 cm in diameter in the left lobe of the liver. DIAGNOSES Based on the results of imaging studies, intrahepatic cholangiocellular carcinoma was suspected, and then surgery was performed. Microscopic findings showed that the tumor was a hepatic MALT lymphoma, and immunohistochemical analysis revealed that the lymphoma cells were CD20+, CD79a+, BCL-2+, CD3-, and CD5-. INTERVENTIONS The patient received rituximab after surgery. OUTCOMES He was free of disease for 13 months at the time of this report. LESSONS Since previously published case reports and our case described nonspecific clinical features of this rare disease, it was usually misdiagnosed before histological confirmation and surgery resection may be a good choice for both diagnosis and local therapy.

Abstract
Primary pulmonary lymphomas represent a pathologically heterogeneous group of disorders that often share imaging features, which include peribronchovascular nodules and masses or areas of nonresolving consolidation. Primary mediastinal B-cell lymphoma is an extranodal non-Hodgkin lymphoma seen in younger patients that has imaging and pathologic features that demonstrate some degree of overlap with Hodgkin lymphoma. Primary lymphomas of the pleural space are rare and associated with concomitant viral infections.

Abstract
RATIONALE AND OBJECTIVE The burden of non-Hodgkin lymphoma (NHL) has increased in some Central and South American countries. We describe the current patterns and trends in NHL incidence and mortality in Central and South America. METHODS We obtained regional- and national-level incidence data from 48 population-based cancer registries in 13 countries, and national-level cancer mortality data from the WHO mortality database for 18 countries. We estimated world population age-standardized incidence rates (ASRs) and mortality rates (ASMRs) per 100,000 person-years for 2003-2007, and presented distributions by histological subtype. RESULTS NHL incidence and mortality rates varied between countries by 2-8- and 6-fold, respectively. ASRs per 100,000 ranged from 1.4 to 10.9 among males and 1.3-9.2 among females. Corresponding ASMRs were between 0.5 and 4.8 among males and between 0.5 and 3.0 among females. The highest incidence was observed in Uruguay (males), Ecuador, Peru and Colombia (males). The highest mortality was seen in Uruguay and Costa Rica. Trends in NHL incidence and mortality in Argentina, Brazil, Chile and Costa Rica did not show marked changes. B-cell neoplasms and NHL not otherwise specified (NOS) accounted for 44% and 34% of all NHL cases. Diffuse large B-cell lymphoma, NOS, was the most frequent histological subtype. CONCLUSION The geographic variations in NHL rates may partially reflect differences in registration practices, disease classification, diagnostic practice, and death certification quality. There is a need for high-quality data and improvements in the accuracy of NHL histological diagnosis. Given the expected increase in NHL, careful monitoring of rates remains a priority to guide cancer control programs.

Abstract
PURPOSE Whereas the different somatostatin receptor (SSTR) subtypes and the chemokine receptor CXCR4 are known to be expressed in a wide variety of human malignancies, comprehensive data are still lacking for MALT-type lymphomas. METHODS Overall, 55 cases of MALT-type lymphoma of both gastric and extragastric origin were evaluated for the SSTR subtype and CXCR4 expression by means of immunohistochemistry using novel monoclonal rabbit antibodies. The stainings were rated by means of the immunoreactive score and correlated with clinical data. RESULTS While the CXCR4 was detected in 92 % of the cases investigated, the SSTR subtypes were much less frequently present. The SSTR5 was expressed in about 50 % of the cases, followed by the SSTR3, the SSTR2A, the SSTR4 and the SSTR1, which were present in 35, 27, 18 or 2 %, respectively, of the tumors only. Gastric lymphomas displayed a significantly higher SSTR3, SSTR4 and SSTR5 expression than extragastric tumors. A correlation between CXCR4 and Ki-67 expression was seen in gastric lymphomas, whereas primarily in extragastric tumors SSTR5 negativity was associated with poor patient outcome. CONCLUSIONS The CXCR4 may serve as a promising target for diagnostics and therapy of MALT-type lymphomas, while the SSTRs appear not suitable in this respect.

Abstract
Clinical data regarding mucosa-associated lymphoid tissue lymphoma (MALToma) solely involving the duodenum are sparse because of the relative rarity of the disease. A comprehensive literature review revealed only 17 cases reported until 2004, and only a moderate number of cases have been reported since. MALToma can be asymptomatic in its very early stages but frequently produces localized or nonspecific symptoms, including early satiety, abdominal pain, vomiting, and involuntary weight loss in later stages. While gastric MALToma is strongly associated with gastric Helicobactor pylori infection, duodenal MALToma is often unassociated with H. pylori infection. A 74-year-old female presented with only dysphagia (without symptoms referable to a duodenal lesion), without systemic 'B' symptoms, and with no evident duodenal lesions at esophagogastroduodenoscopy; however, she was diagnosed with duodenal MALToma by pathologic examination of random duodenal biopsies performed to exclude celiac disease. An important clinical feature of this case is that duodenal MALToma was diagnosed by pathologic analysis of duodenal biopsies despite (1) no endoscopically apparent duodenal lesions; (2) duodenal involvement without gastric involvement; (3) lack of symptoms attributable to duodenal MALToma, and (4) absence of evident H. pylori infection. This work shows that early duodenal MALToma can be difficult to diagnose because of absent symptoms, absence of gastric involvement, absence of endoscopic abnormalities, and absence of H. pylori infection; it may require random duodenal biopsies for diagnosis.

Autoimmune/Inflammatory Arthritis Associated Lymphomas: Who Is at Risk? BIOMED RESEARCH INTERNATIONAL 2016; 2016:8631061.

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

Abstract
Very sparse literature exists that describe the clinical profile of primary MZL of breast. Radiotherapy alone might cure an indolent lymphoma localized to breast (i.e. stage IE). 5-yr survival rates of surgery are inferior to radiotherapy and chemo-radiation. Greater appreciation of the lesser role of surgery is warranted.
Introduction Primary breast lymphoma by definition is localized to one or both the breasts with or without involvement of regional lymph nodes with no other extra mammary site involvement. Role of surgery in the treatment armamentarium is less well defined. Presentation of case A 62 year old post-menopausal lady was found to have 1.2 × 1.2 × 0.6 cm mass in the left breast on diagnostic mammography. Core needle biopsy reveals marginal zone lymphoma. Complete staging work-up was performed which was negative for regional spread and metastatic foci. She was diagnosed to have a localized stage IE extra nodal low grade marginal zone lymphoma of the MALT type involving breast. She received radiotherapy to the breast and is in remission at follow up after one year. Discussion Accurate diagnosis requires adequate tissue biopsy either by a core needle or a surgical biopsy for histopathologic evaluation and immunophenotyping. Immunohistochemically the tumors are positive for pan B-cell markers (CD 19, CD 20, CD22, and CD 79a) and lack T cell markers. For stage IE Marginal zone lymphoma radiotherapy alone and for stage IIE combined chemo-radiation offers the best possible control of the disease. Progression free survival for MZL is better than diffuse large B-cell lymphoma. Conclusion At present the best evidence support radiotherapy in localized disease and combined chemo-radiation in advanced disease. Role of surgery is minimal and is seen in case of diagnostic dilemma. Rarity of the diagnosis precludes large scale prospective studies making therapeutic decisions difficult and challenging.

Abstract
Background Extra-nodal marginal zone B cell lymphoma of mucosa-associated lymphoid tissue originating in the liver is less common. Case presentation We described the clinical presentation, immunohistochemistry, and immunophenotypes of this lymphoma, which was misdiagnosed with tiny hepatic carcinoma in a 44-year-old woman with hepatitis C; the patient underwent left lateral sectionectomy. The immunophenotype identified the most of the lymphoid cells as positive CD20, CD34, Ki67, CD3, CD4, CD79a, CD45RO, MUM-1, and CD5 and negative CD10, CD15, CD30, ACT, CK, CRO, DES, and HMB45. The diagnosis of primary hepatic mucosa-associated lymphoid tissue (MALT) was made by histology after surgery; the patient went through the excellent recovery with no chemotherapy and is disease free for 27 months. Conclusions Primary hepatic MALT is less common with incidental finding; local resection is beneficial due to its oncological indolence.

Abstract
BACKGROUND The initial staging work-up of gastric mucosa-associated lymphoid tissue (MALT) lymphoma includes bone marrow examination. Since gastric MALT lymphoma is mostly detected in early stages with the national cancer screening programme in Korea, bone marrow is rarely involved. AIMS To investigate the incidence of bone marrow involvement in gastric MALT lymphomas and the role of bone marrow examination for an initial staging work-up. METHODS Patients diagnosed with gastric MALT lymphoma at Seoul National University Hospital from January 2005 to July 2014 were enrolled. Clinical databases of the patients were retrospectively reviewed. RESULTS Out of 105 patients, 91 (86.7%) were classified as stage IE1. Among these patients, 78 patients with Helicobacter pylori infection underwent eradication therapy, and complete remission was achieved in 74 cases (94.9%). Twelve out of 13 patients (92.3%) without H. pylori infection underwent radiotherapy or surgery and all achieved complete remission. Bone marrow involvement was proven in only one patient (1.0%). CONCLUSION Bone marrow involvement was rare in patients with only superficial gastric MALT lymphoma without extragastric invasion. Further studies are warranted to identify the risk factors of bone marrow involvement in gastric MALT lymphoma.

Abstract
Background. The purpose of this study was to compare the accuracy of whole-body MRI with diffusion-weighted sequences (WB-DW-MRI) with that of 18F-FDG-PET/CT in the staging of patients with primary gastrointestinal lymphoma. Methods. This retrospective study involved 17 untreated patients with primary abdominal gastrointestinal lymphoma. All patients underwent 18F-FDG-PET/CT and WB-DW-MRI. Histopathology findings or at least 6 months of clinical and radiological follow-up was the gold standard. The Musshoff-modified Ann Arbor system was used for staging, and diagnostic accuracy was evaluated on a per-node basis. Results. WB-DW-MRI exhibited 100% sensitivity, 96.3% specificity, and 96.1% and 100% positive and negative predictive values (PPV and NPV), respectively. The sensitivity, specificity, and PPV and NPV of PET/CT were 95.9%, 100%, and 100% and 96.4%, respectively. There were no statistically significant differences between the two techniques (p = 0.05). The weighted kappa agreement statistics with a 95% confidence interval were 0.97 (0.95–0.99) between the two MRI readers and 0.87 (0.82–0.92) between the two methods. Conclusions. WB-DW-MRI appears to have a comparable diagnostic value to 18F-FDG-PET/CT in staging patients with gastrointestinal lymphoma.

Abstract
Lymphomas are the group of neoplasms originating from lymphoreticular system mainly from lymph nodes, among them up to 40% of non-Hodgkin's lymphomas present extra nodally. In oral cavity, lymphomas are least common and account for 3–5% of all malignancies, presenting mainly in older age groups with male predominance. According to Revised European-American Lymphoma classification, among B-cell and T-cell subtypes of non-Hodgkin's lymphomas, diffuse large B-cell lymphoma (DLBCL) is the most common, characterized by diffuse proliferation of large neoplastic B lymphoid cells. Here we present a case report of DLBCL affecting oral cavity involving left buccal vestibule and extending onto the palate, along with its clinical, histopathologic and immunohistochemical features.

Abstract
We present a paediatric case of infectious mononucleosis in a 13-year old, manifesting with follicular conjunctivitis and a conjunctival mass in one eye with no evidence of leucocytosis on the blood count. The diagnosis was confirmed following surgical excision and biopsy. The case represented a diagnostic challenge due to its atypism and given the steady increase in the prevalence of EBV-related ocular diseases in the last years, this report can serve as an example to prompt earlier serological tests to identify the aetiology in similar cases. This is important because EBV can be treated with acyclovir early in the active viral phase.

Abstract
Descriptive epidemiology on incidence and survival by lymphoid neoplasm (LN) subtypes using the 2008 World Health Organisation (WHO) classification remained limited in Asia. The aim of this study was to evaluate whether gender and ethnic differences in incidence and survival of LN subtypes existed using the Singapore Cancer Registry (SCR) from 1998 to 2012. We derived age standardised incidence rates (ASIRs) by the direct standardisation method and 5-year relative survival (RSR) by the Ederer II method and period approach. Five-year observed survival (OS) was obtained for each ethnicity. Malays had the highest ASIR of total LNs among the three ethnicities for each time period. The largest increase in 5-year RSR subtypes was follicular lymphoma from 43.8% in 1998-2002 to 82.3% in 2008-2012; followed by chronic lymphocytic leukaemia (CLL)/small lymphocytic lymphoma (SLL) from 48.1% in 1998-2002 to 77.9% in 2008-2012. Although males had higher incidence than females in each time period, females had greater 5-year RSR for follicular lymphoma (89.8% in 2008-2012 for females vs. 76.6% in 2008-2012 for males) and CLL/SLL (78.7% in 2008-2012 for females vs. 76.7% in 2008-2012 for males). All three ethnicities experienced an overall increase in 5-year OS for mature B-cell lymphoma, with Indians experiencing the greatest increase (37.1% in 1998-2002 to 61.1% in 2008-2012), followed by Malays (30.8% in 1998-2002 to 48.7% in 2008-2012) and then Chinese (36.4% in 1998-2002 to 51.3% in 2008-2012). Our study demonstrated that improved mature B-cell lymphoma survival was not only observed in the West, but also in Singapore.

Abstract
We report a rare case of primary non-Hodgkin’s B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT) type occurring in the urinary bladder. A 70-year-old woman presented with gross haematuria, and an abdominal CT scan revealed a bladder tumour which was resected endoscopically. Histopathological diagnosis was confirmed by immunohistochemical staining and treated successfully with radiotherapy.

Abstract
Helicobacter pylori (H. pylori) is a Gram-negative spiral bacterium, classified as a carcinogen of class I, according to the World Health Organization (WHO). The infection is a major cause of gastritis, gastric and duodenal ulcer disease and increases the risk of gastric cancer. It has been implicated in the pathogenesis of several gastrointestinal, systemic or hematological diseases. The present review aims in deciphering the role of the bacterium in hematological disorders, increasing the awareness of gastroenterologists, hematologists and internal medicine practitioners, regarding the bacterium-associated hematological diseases. The efficacy of H. pylori eradication in increasing the platelet count in adult patients with primary immune thrombocytopenia (ITP) has been confirmed, linking the infection with the disease. Moreover, as the bacterium causes iron deficiency anemia (IDA) by several mechanisms, recent guidelines indicate H. pylori infection (Hp-I) to be sought in IDA patients if histology is negative and to be eradicated if present. Furthermore, it has been widely recognized that anti-H. pylori treatment causes regression of the low-grade B-cell gastric MALT lymphomas. Despite the well established associations of Hp-I with the aforementioned hematological disorders, we highlight the possible role of the infection to other hematological diseases or conditions such as non-Hodgkin lymphomas of the stomach, monoclonal gammopathy of undetermined significance, megaloblastic anemia and myelodysplastic syndromes. We finally underline the elevated risk of childhood leukemia and of hemorrhage in patients with coagulation disorders, due to the infection.

Abstract
Mucosa-associated lymphoid tissue (MALT) lymphoma is a diagnostic challenge when arising from bronchiolar submucosal tissue. The case herein describes a man with a lung mass and a remote history of gastric MALT lymphoma. After undergoing a bronchoscopic examination and tissue sampling, he was diagnosed with pulmonary recurrence of gastric MALT lymphoma. The diagnosis of MALT lymphoma in the lung can be challenging. Radiographic findings are typically nonspecific, and tissue biopsy by surgical means is often required. The diagnosis of bronchus-associated lymphoid tissue lymphoma has been previously demonstrated bronchoscopically when a needle aspiration is performed. This case supports the position that bronchoscopy with needle aspiration, and flow cytometry should be performed in all patients in whom pulmonary MALT lymphoma is suspected.

Abstract
The aim of this study was to assess the clinical characteristics, treatment results, and analyze the prognostic factors among patients with extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma). We retrospectively reviewed 98 patients with MALT lymphoma consecutively diagnosed at the Cancer Institute Hospital. Eighty-one patients (82%) had localized disease and 17 patients (17%) had advanced disease. The primary site was gastric in 52, and extra-gastric in 46. With a median follow-up of 40 months, the estimated 3-year overall survival (OS) and progression free survival (PFS) of the entire group were 100% and 89%, respectively. Three-year PFS was significantly better in patients with gastric lymphoma than in those with non-gastric lymphoma (95% vs. 82%, p = 0.043). Patients with localized disease had significantly better 3-year PFS than those with advanced disease (94% vs. 73%, p = 0.026). Upon multivariate analysis, non-gastric lymphoma retained prognostic significance for PFS.

Abstract
Abstract
Multiple myeloma (MM) is a currently incurable neoplasm of terminally differentiated B cells. The translocation and/or overexpression of c-MAF have been observed in human MM. Although c-MAF might function as an oncogene in human MM, there has been no report thus far describing the direct induction of MM by c-MAF overexpression in vivo. In this study, we have generated transgenic (TG) mice that express c-Maf specifically in the B-cell compartment. Aged c-Maf TG mice developed B-cell lymphomas with some clinical features that resembled those of MM, namely, plasma cell expansion and hyperglobulinemia. Quantitative RT-PCR analysis demonstrated that Ccnd2 and Itgb7, which are known target genes of c-Maf, were highly expressed in the lymphoma cells. This novel TG mouse model of the human MM t(14;16)(q32;q23) chromosomal translocation should serve to provide new insight into the role of c-MAF in tumorigenesis.
