Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue of the ileum in an adult presenting with intussusception: a case report and literature review. Front Oncol 2024; 14:1395144. [PMID: 38919535 PMCID: PMC11196823 DOI: 10.3389/fonc.2024.1395144] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2024] [Accepted: 05/10/2024] [Indexed: 06/27/2024] Open
Abstract
Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (EMZL), also known as MALT lymphoma, is an extranodal multiorgan-invasive proliferative lymphoma composed of small B cells with variable morphology. It most commonly occurs in the digestive tract, with a high prevalence in the stomach, but EMZL originating in the small intestine is rare and lacks specificity in clinical manifestations, which makes it easy to be misdiagnosed. Herein, we report a rare case of small intestinal EMZL presentation as intussusception in a 32-year-old man. A colonoscopy performed at the local hospital revealed a pedicled polyp about 5 cm × 5 cm in size with a rough surface, and hyperemia was seen in the ileocecal region. He was admitted to our hospital for a polypectomy. A contrast-enhanced computed tomographic (CT) scan suggested ileocolic intussusception, which was subsequently confirmed by a colonoscopy in our hospital. Adult intussusception is relatively rare, with 90% of cases having a known causative mechanism and 40% of cases caused by primary or secondary malignancies. Therefore, we performed a laparoscopic-assisted right hemicolectomy for the patient. The resected specimen showed that the terminal ileum was intussuscepted into the ascending colon, and the intussusception was hyperemia and edema. A 2.5 cm × 2.5 cm × 1.5 cm mass was seen at the end of the intussusception. Postoperative pathology revealed that the mass was EMZL, partially transformed into a large B-cell lymphoma. The patient was transferred to the hematology department and completed a PET-CT showing postoperative manifestations of primary intestinal lymphoma, Lugano staging IE2. Although EMZL was an indolent lymphoma and the patient was in the early stages, the rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) regimen was given in view of the histological transformation. The patient is in regular follow-up. This was a rare case of small intestinal mass due to EMZL presented as intussusception in adults, which highlighted laparoscopic-assisted enterectomy as a potential therapeutic approach in the multidisciplinary collaborative therapy of small intestine EMZL.

Abstract
B-cell lymphomas occur with an incidence of 20 new cases per 100 000 people per year in high-income countries. They can affect any organ and are characterised by heterogeneous clinical presentations and courses, varying from asymptomatic, to indolent, to very aggressive cases. Since the topic of B-cell non-Hodgkin lymphomas was last reviewed in The Lancet in 2017, a deeper understanding of the biological background of this heterogeneous group of malignancies, the availability of new diagnostic methods, and the development and implementation of new targeted and immunotherapeutic approaches have improved our ability to treat patients. This Seminar provides an overview of the pathobiology, classification, and prognostication of B-cell non-Hodgkin lymphomas and summarises the current knowledge and standard of care regarding biology and clinical management of the most common subtypes of mature B-cell non-Hodgkin lymphomas. It also highlights new findings in deciphering the molecular background of disease development and the implementation of new therapeutic approaches, particularly those targeting the immune system.

Abstract
Introduction and importance Extranodal marginal zone lymphoma (EMZL lymphoma), also known as mucosa-associated lymphoid tissue (MALT) lymphoma, is a rare B-cell lymphoma that rarely affects children. The involvement of infectious agents, especially H. pylori, has been observed in the formation and progression of MALT lymphoma in the stomach. Hematemesis as the primary clinical manifestation is uncommon, highlighting the need for case studies with this presentation. This article uses SCARE2023 criteria as a framework to sort out a case report in order. Case presentation A 13-year-old female patient was admitted in August 2022 with an episode of hematemesis. She had a prior diagnosis of anaemia and was found positive for H. pylori. Despite treatment, she developed symptoms of chronic non-atrophic gastritis and had recurring episodes of hematemesis. Physical and diagnostic examinations revealed B-cell lymphoma localized in the gastric antrum. The primary diagnosis was extranodal MALT lymphoma with unique plasma cell differentiation. Clinical discussion The presentation of gastric MALT lymphoma can be variable, with definitive diagnosis often achieved via endoscopic biopsy. H. pylori plays a significant role in the onset and progression of this lymphoma, emphasizing the importance of its eradication for treatment. Effective outcomes can be achieved through anti-H. pylori treatment, although it is essential for clinicians to ensure its complete eradication post-treatment. Conclusion Paediatric presentation of gastric MALT lymphoma, especially with hematemesis as the primary symptom, is rare and can be easily misdiagnosed. Compared to adults, children generally exhibit a better prognosis with effective H. pylori treatment. It is vital for medical professionals to recognize the differences in presentation between children and adults to ensure accurate diagnosis and treatment.

Abstract
Extranodal marginal zone B-cell lymphoma (ENMZL) of mucosa-associated lymphoid tissue (MALT), a rare subtype of B-cell lymphoma, is typically associated with Helicobacter pylori (H pylori) infection, especially in gastric cases. However, this article presents 2 unique cases of H pylori-negative colonic ENMZL, challenging the conventional understanding of the disease. The first case involves an 80-year-old male diagnosed with Stage 1E ENMZL in the descending colon, and the second describes a 74-year-old male with sigmoid colon ENMZL. Both cases lacked H pylori infection, adding complexity to their management. Accompanying these case studies is a comprehensive literature review, delving into the epidemiology, pathology, clinical features, diagnosis, and treatment of H pylori-negative ENMZL, with a focus on gastrointestinal involvement. This review highlights the importance of considering H pylori-negative cases in ENMZL diagnosis and management, illustrating the need for further research and individualized treatment approaches in this uncommon lymphoma subtype.

Abstract
BACKGROUND Mucosa-associated lymphoid tissue (MALT) lymphoma is a distinct subtype of non-Hodgkin B cell lymphoma that mostly involves the gastrointestinal tract. The stomach is the most commonly affected site whereas colorectal involvement occurs very rarely. Given its rarity, the management and clinical outcome of colorectal MALT lymphoma are not well established yet.
CASE SUMMARY From the superficial capillary bed in the lower rectum. Endoscopic ultrasonography showed homogenous hypoechoic lesions in the deep mucosal layer. Endoscopic submucosal dissection (ESD) was done for accurate histologic diagnosis and treatment and both the rectal lesions were completely removed en bloc and subsequently diagnosed as primary rectal MALT lymphoma. Herein, we report a case of primary rectal MALT lymphoma in a 68-year-old woman that was treated by only ESD, and the 12-month follow-up revealed no tumour recurrence.
CONCLUSION These results of our case and previous reports suggest that endoscopic resection alone may be a feasible and safe treatment for primary colorectal MALT lymphoma and allows organ preservation.

Abstract
Between January 2010 and December 2015, we enrolled 28 patients with stage IEI/IIE1 extragastric mucosa-associated lymphoid tissue (MALT) lymphoma who received first-line antibiotic treatment, after informing them about the pros and cons of alternative therapies. In addition, during the same period, 64 patients with stage IE/IIE1 disease who received conventional treatment were selected as the control group. The most common primary sites were the ocular adnexal area (17 cases), followed by the salivary glands (four cases), pulmonary (three cases), and thyroid, trachea, larynx, and colon region (one case each). First-line antibiotic treatment resulted in an overall response rate of 57.1%: 12 patients achieved complete remission (CR), while four achieved partial remission (antibiotic-responsive tumors). Monoclonal gammopathy was significantly prevalent in antibiotic-unresponsive tumors than in antibiotic-responsive tumors (50.0% [6/12] vs. 12.5% [2/16], p = 0.044). After a median follow-up of 7 years, all patients with CR remained lymphoma-free, with 7-year event-free survival (EFS) and overall survival (OS) rates of 62.7% and 96.4%, respectively. The 7-year EFS and OS rates of patients who received conventional treatments were 73.1% and 91.1%, respectively. Compared with that noted in patients who received conventional treatment, antibiotic treatment was effective in some patients with localized extragastric MALT lymphoma.

Abstract
OBJECTIVES Lymphoma, categorized as either non-Hodgkin's lymphoma or Hodgkin's lymphoma, is the second most common malignancy in the head and neck. Primary tongue lymphoma is exceedingly rare, with only case reports or small case series in the literature. This population-based analysis is the first to report the epidemiology and prognostic factors of survival in patients with primary tongue lymphoma. METHODS The Surveillance, Epidemiology, and End Results 18 database from the National Cancer Institute was queried for patients diagnosed between the years 2000 and 2016 with tongue lymphoma. Outcomes of interest were overall and disease-specific survival. Independent variables included age at diagnosis, sex, race, marital status, primary subsite, histologic subtype, stage, and treatment type. RESULTS AND CONCLUSION Seven hundred forty patients met criteria; the male-female ratio was 1.5:1 and the mean age at diagnosis was 67.8 years. The majority of lesions localized to the base of tongue (90.0%), were histologically diffuse large B-cell lymphoma (59.5%), and presented at stage I or II (77.9%). Most early-stage lymphomas were treated with chemotherapy only (40.5%) or a combination of both chemotherapy and radiation (31.3%), while late-stage cancers were primarily treated with chemotherapy alone (68.5%). In multivariate analysis, younger age at diagnosis, female sex, married/partnered marital status, mucosa-associated lymphoid tissue histologic subtype, and earlier cancer stage were found to be associated with improved survival. Chemotherapy treatment with or without radiation was also associated with better survival compared to no treatment or radiation alone, though data regarding immunotherapy was unavailable.

Abstract
MALT lymphoma is an extranodal B-cell lymphoma of the marginal zone of mucosa-associated lymphoid tissue (MALT), caused by malignant transformation of B-cells in the marginal zone. In this work, we aim to explore the potential relationship between MALT lymphoma and DLBCL. Vaccines derived from messenger ribonucleic acid (mRNA) may provide satisfactory results. Despite being a promising treatment option, immunotherapy isn't widely used in treating renal cell carcinoma, as only a few patients respond to the treatment. The Cancer Genome Atlas (TCGA) analysis revealed gene expression profiles and clinical information. Antigen-presenting cells infiltrated the immune system using TIMER tool (http://timer.cistrome.org/). GDSC (Genomics of Drug Sensitivity in Cancer) data were used to estimate drug sensitivity. Immune-related genes were associated with a better prognosis in MALT lymphoma patients and higher levels of antigen-presenting cells. There is a significant relationship between these immune subtypes and immunological checkpoints, immunogenic cell death regulators, and prognostic variables for MALT lymphoma patients. In this study, we provide a theoretical foundation for the development of mRNA vaccines and suggest that KLHL14 could potentially be used as antigens to develop mRNA vaccines for MALT lymphoma.

Abstract
Nasopharyngeal MALT lymphoma is a rare disease, with limited cases reported in the literature. To the best of our knowledge, there is no research detailing the treatment of nasopharyngeal MALT lymphoma. In this present paper, we report an unusual case of a 70-year-old female patient with nasopharyngeal MALT lymphoma. The patient was treated with radiotherapy alone. The detailed radiation therapy of the treatment was demonstrated. The patient is free of locally recurrent or distant disease at two years. Radiotherapy alone can be a helpful treatment for MALT lymphoma confined to the nasopharyngeal cavity.

Abstract
Extra-nodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) is uncommon and difficult to diagnose due to varied clinical presentations and endoscopic appearances masquerading as other pathology. Rarely, it has been associated with acute upper gastrointestinal (GI) bleeding. We report on a 60-year-old male who presented with an acute upper GI bleed and endoscopic findings suggestive of isolated gastric varices (GV), ultimately determined to be MALT lymphoma. Complete remission was achieved with radiation therapy, with no recurrence at a 12-month follow-up. This case highlights a unique clinical and endoscopic presentation of MALT lymphoma which providers should be aware of. We emphasize the use of endoscopic ultrasound (EUS) evaluation for accurate diagnosis.

Abstract
The aim of this study was to explore the application of computed tomography (CT) images in the diagnosis of gastric tumor under the intelligent reconstruction algorithm (IRA). 120 patients with gastric cancer were selected and all the patients underwent CT scanning, and CT images were analyzed based on the Feldkamp-Davis-Kress algorithm (FDK algorithm) to evaluate the imaging features of gastric lesions. According to biopsy or surgical pathology, the detection rate of CT images was calculated. The results showed that there were three pathological types of benign tumors (polyps, leiomyomas, and mesenchymomas) and three pathological types of malignant tumors (mesenchymomas, adenomas, and lymphomas). In addition, the detection rates of CT scans were different, reaching 94.2% on different orientations of the stomach, 90.7% of benign tumors, and 90.9% of malignant tumors, so the detection rate of different orientations was relatively high. CT images based on the FDK IRA could realize a high detection rate in diagnosis, accurately locate the lesion, and display the characteristics of the lesion and the metastasis of surrounding tissues; there were significant differences between benign and malignant gastric tumors in CT images, and the detection effect was obvious, which is worthy of clinical application and promotion.

Abstract
Treatment of indolent lymphoma has improved significantly in recent decades since the advent of rituximab (anti-CD20 monoclonal antibody). Although, some patients with limited disease can be cured with radiation therapy alone, most patients experience disease progression and recurrence during follow-up despite early initiation of treatment. Thus, watch-and-wait is still regarded the standard for asymptomatic patients. Patients with indolent lymphoma have a significant heterogeneity in terms of tumor burden, symptoms (according to anatomical sites) and the need for instant therapy. Therefore, the initiation of treatment and treatment option should be decided with a clear goal in each patient according to the need for therapy and clinical benefits with the chosen treatment. In this review, we cover the current treatment of follicular lymphoma and marginal zone lymphoma.

Abstract
Simple Summary Extranodal marginal zone lymphoma (EMZL) is an indolent lymphoproliferative disease morphologically composed of small heterogeneous B lymphocytes. It generally occurs with a localized stage and can arise in various organs, the most frequent being the stomach, lung, and ocular adnexa. Depending on the presentation and the possible association with infectious agents, different therapeutic approaches are to be undertaken. The purpose of this review is to describe the biology underlying this pathology, the diagnostic, and therapeutic approach. Abstract Extranodal Marginal Zone Lymphoma (EMZL lymphoma) is an indolent B-cell lymphoma with a median age at diagnosis of about 60 years. It accounts for 7–8% of all B-cell lymphomas. It can occur in various extranodal sites, including stomach, lung, ocular adnexa, and skin; furthermore, the disseminated disease can be found in 25–50% of cases. Several infectious agents, such as Helicobacter pylori (H. Pylori) in the case of gastric Mucosa Associated Lymphoid Tissue (MALT) Lymphoma, can drive the pathogenesis of this cancer, through the autoantigenic stimulation of T cells, but there may also be other factors participating such autoimmune diseases. Initial staging should include total body computed tomography, bone marrow aspirate, and endoscopic investigation if indicated. Fluorescence in situ hybridization (FISH), should be performed to detect the presence of specific chromosomal translocations involving the MALT1 and BCL10 genes, which leads to the activation of the NF-κB signaling pathway. Depending on the location and dissemination of the disease, different therapeutic choices may include targeted therapy against the etiopathogenetic agent, radiotherapy, immunochemotherapy, and biological drugs. The purpose of this review is to illustrate the complex biology and the diagnosis of this disease and to better define new treatment strategies.

All patients with primary gastrointestinal lymphoma diagnosed in PET Center of Zhebei Mingzhou Hospital in Huzhou from August 2013 to April 2021 were analyzed retrospectively. In addition, the pathology and immunohistochemistry of these patients were retrieved from the inpatient system of Huzhou Central Hospital. The results showed that the male-female ratio of these 78 patients was about 1.29/1 (including 44 males and 34 females), with a median age of 63 years old (20–90 years old). The most frequent sites in order of its occurrence were the stomach (51.3%), small intestine (34.6%), ileocecal region (9%) and colon (5.1%). T-cell lymphoma accounted for 10.7% of primary gastrointestinal lymphoma, and all of them were found in small intestines, while B-cell lymphoma accounted for 89.3%.

Abstract
This meta-analysis aims to concisely summarize the genetic landscape of splenic, nodal and extranodal marginal zone lymphomas (MZL) in the dura mater, salivary glands, thyroid, ocular adnexa, lung, stomach and skin with respect to somatic variants. A systematic PubMed search for sequencing studies of MZL was executed. All somatic mutations of the organs mentioned above were combined, uniformly annotated, and a dataset containing 25 publications comprising 6016 variants from 1663 patients was created. In splenic MZL, KLF2 (18%, 103/567) and NOTCH2 (16%, 118/725) were the most frequently mutated genes. Pulmonary and nodal MZL displayed recurrent mutations in chromatin-modifier-encoding genes, especially KMT2D (25%, 13/51, and 20%, 20/98, respectively). In contrast, ocular adnexal, gastric, and dura mater MZL had mutations in genes encoding for NF-κB pathway compounds, in particular TNFAIP3, with 39% (113/293), 15% (8/55), and 45% (5/11), respectively. Cutaneous MZL frequently had FAS mutations (63%, 24/38), while MZL of the thyroid had a higher prevalence for TET2 variants (61%, 11/18). Finally, TBL1XR1 (24%, 14/58) was the most commonly mutated gene in MZL of the salivary glands. Mutations of distinct genes show origin-preferential distribution among nodal and splenic MZL as well as extranodal MZL at/from different anatomic locations. Recognition of such mutational distribution patterns may help assigning MZL origin in difficult cases and possibly pave the way for novel more tailored treatment concepts.

Abstract
Carriers of the mutated CDH1 gene have an increased risk of developing early-onset signet-ring cell (diffuse) gastric cancer. We present a case of a young patient with a confirmed mutation of the CDH1 gene, who was diagnosed with a gastric marginal zone B-cell lymphoma (MZL) of mucosa-associated lymphoid tissue (MALT lymphoma) from surveillance endoscopy. He underwent Helicobacter pylori eradication treatment and was subsequently submitted to a total prophylactic gastrectomy. The surgical specimen only revealed foci of signet-ring cell carcinoma (SRCC) in situ without lymphoma signs. We highlight here the occurrence of other pathology in high-risk patients as well as its possible influence on the decision to perform gastrectomy.

Abstract
PURPOSE MALT lymphoma is thought to have a genetic component. Genetic studies in the greek population are rare and genetic determinants remain to be established. The current study aimed to seek correlations between genetic polymorphisms and risk of MALT lymphoma in the Greek population. PATIENTS AND METHODS 83 MALT lymphoma patients and 60 age-matched healthy outpatients were recruited. SNPs in TNFa, LTA and CTLA-4 genes and IL1RN-VNTR and GSTT1 and GSTTM1 null polymorphisms were genotyped using published PCR/PCR-RFLP methods, while two novel PCR-RFLP methods were developed for IL-22 rs7314777 and TCF19 rs7750641 SNPs. Part of the results was validated by DNA-sequencing. Statistical analysis was performed using SPSS and the SNPstats bioinformatic tool. RESULTS The mean age of the patients and controls were 55.9 and 56.2 years respectively. The majority of patients (63) suffered gastric marzinal zone lymphoma (GMZL) and 71.1% were stage I at diagnosis. A statistically significant association was noted for the CTLA-4 49A/ G G variant (OR:2.56,p: 0.006) and the TCF19 rs7750641 SNP T variant (OR: 3.86, p:0.023). CONCLUSIONS Our study confirmed a role for CTLA-4 49A/G and TCF19 rs7750641 SNPs in the Greek population. Additional studies could help confirm these associations and possibly link them to prognosis or response to treatment parameters.

Abstract
Helicobacter pylori (H pylori) infection can cause chronic gastritis, peptic ulcer, and even gastric cancer, so effective eradication is critical.This study compared the efficacy and safety of bismuth quadruple regimens including either tetracycline or furazolidone for initial eradication.Patients newly diagnosed with H pylori infection from January 2020 to January 2021 were randomly assigned to receive either the tetracycline-containing regimen (n = 116) or furazolidone-containing regimen (n = 168). Both regimens included 1 proton pump inhibitor (rabeprazole 20 mg, or esomeprazole 20 mg, or eprazole 5 mg), colloidal pectin bismuth 300 mg, and amoxicillin 1000 mg in addition to tetracycline 1.0 g or furazolidone 0.1 g. All drugs were administered twice daily for 12 consecutive days. The 14C urea breath test was used for diagnosis, and re-test negativity at one-month follow-up was considered successful eradication. Adverse events were recorded during follow-up by telephone interview.In total, 109 patients in the tetracycline group and 157 in the furazolidone group were re-examined at 1 month. In the tetracycline group, 101 patients tested negative at follow-up, yielding an eradication rate of 92.7% according to per-protocol analysis and 87.1% by intention-to-treat analysis. In the furazolidone group, 141 patients tested negative, yielding eradication rates of 89.8% by PP and 83.9% by ITT. Eradication rates did not differ significantly between regimens (per-protocol: χ2 = 0.637, P = .517; intention-to-treat: χ2 = 0.537, P = .501). However, total adverse events incidence was significantly lower in the tetracycline group (20.2% vs 37.6%; χ2 = 9.193, P = .003).Both bismuth quadruple regimens produce high initial eradication, but the tetracycline regimen appears safer.

Elucidated tumorigenic role of MAML1 and TWIST1 in gastric cancer is associated with Helicobacter pylori infection. Microb Pathog 2021; 162:105304. [PMID: 34818576 DOI: 10.1016/j.micpath.2021.105304] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2021] [Revised: 11/12/2021] [Accepted: 11/18/2021] [Indexed: 12/23/2022]
Abstract
BACKGROUND Epithelial-mesenchymal transition (EMT) has a fundamental role in tumor initiation, progression, and metastasis. Helicobacter pylori (HP) induces EMT and thus causes gastric cancer (GC) by deregulating multiple signaling pathways involved in EMT. TWIST1 and MAML1 have been confirmed to be critical inducers of EMT via diverse signaling pathways such as Notch signaling. This study aimed to investigate for the first time possible associations between TWIST1/MAML1 mRNA expression levels, HP infection, and clinicopathological characteristics in GC patients. METHOD TWIST1 and MAML1 mRNA expression levels were evaluated in tumoral and adjacent normal tissues in 73 GC patients using the quantitative reverse transcription PCR (RT-qPCR) method. PCR technique was also applied to examine the infection with HP in GC samples. RESULTS Upregulation of TWIST1 and MAML1 expression was observed in 35 (48%) and 34 (46.6%) of 73 tumor samples, respectively. Co-overexpression of these genes was found in 26 of 73 (35.6%) tumor samples; meanwhile, there was a significant positive correlation between MAML1 and TWIST1 mRNA expression levels (P < 0.001). MAML1 overexpression exhibited meaningful associations with advanced tumor stages (P = 0.006) and nodal metastases (P ˂ 0.001). 34 of 73 (46.6%) tumors tested positive for HP, and meanwhile, MAML1 expression was positively related with T (P = 0.05) and grade (P = 0.0001) in these HP-positive samples. Increased TWIST1 expression was correlated with patient sex (P = 0.035) and advanced tumor grade (P = 0.017) in HP-infected tumors. Furthermore, TWIST1 and MAML1 expression levels were inversely linked with histologic grade in HP-negative tumor samples (P = 0.021 and P = 0.048, respectively). CONCLUSION We propose TWIST1 and MAML1 as potential biomarkers of advanced-stage GC that determine the characteristics and aggressiveness of the disease. Based on accumulating evidence and our findings, they can be introduced as promising therapeutic targets to modify functional abnormalities in cells that promote GC progression. Moreover, HP may enhance GC growth and metastasis by disrupting TWIS1/MAML1 expression patterns and related pathways.

Abstract
Primary gastric lymphoma is rare, representing 5% of all primary gastric neoplasms. The presenting complaints of gastric mucosa-associated lymphoid tissue (MALT) lymphoma are usually nonspecific. However, life-threatening gastrointestinal bleeding from the stomach is unusual and sparsely reported. While studies reveal an indolent course, we present a case that presented with massive and recurrent hematemesis leading to hypovolemic shock secondary to endoscopically confirmed MALT lymphoma, which was treated with radiotherapy to achieve remission. She had no autoimmune diseases and tested negative for Helicobacter pylori. Our case emphasizes the importance of early diagnosis and timely intensive radiotherapy of a localized but aggressive gastric MALT lymphoma.

Abstract
PURPOSE OF THE REVIEW Primary GI lymphomas of B cell origin are a diverse group of lymphomas. In this article, we provide an overview of the diagnosis, pathologic and molecular features, and management of these varied lymphomas. RECENT FINDINGS The most common primary GI lymphomas are diffuse large B cell lymphoma (DLBCL) and marginal zone lymphomas (MZL), but follicular lymphomas (FL), mantle cell lymphomas (MCL), post-transplant lymphoproliferative disorders (PTLD), and Burkitt lymphoma of the GI tract also occur. Many features of these lymphomas are similar to their nodal counterparts, but certain clinical and biological aspects are unique. Diagnostic and treatment strategies for these lymphomas continue to evolve over time. There are ongoing discoveries about the unique pathophysiology, molecular characteristics, and complications of primary B cell GI lymphomas that are already leading to improvements in management of this histologically diverse set of lymphomas.

Abstract
The stomach is the most frequent site of extranodal lymphoma. Mucosa-associated lymphoid tissue (MALT) lymphoma is a low-grade, B-cell neoplasm strongly associated with Helicobacter pylori (HP) infection. The presenting complaints of gastric MALT lymphoma are usually nonspecific. HP eradication is regarded as the first-line therapy in early stage disease. Management of patients who failed to achieve remission following HP eradication include chemotherapy, radiotherapy and in selected cases, surgery. The aim of the present study was to examine the clinical characteristics and treatment outcome of patients with gastric MALT lymphoma.

Abstract
RATIONALE Dieulafoy lesion (DL), a rare cause of gastrointestinal bleeding, is easily covered by blood scab formation on the mucous membrane for its small size, which makes it difficult to be identified under endoscope. In clinical practice, it is also very easy to miss gastric mucosa-associated lymphoid tissue (MALT) lymphoma that exhibits atypical early manifestations under gastroendoscope and is difficult to be diagnosed by routine superficial biopsy. Most patients only experience nonspecific dyspepsia symptoms. PATIENT CONCERNS A 68-year-old man suffering from repeated melena for 6 years arrived at our hospital. The patient had undergone gastroscopy and capsule endoscopy at other hospitals for several times and received symptomatic treatment, but his melena still continued to recur. At our hospital, the capsule endoscopy displayed that there existed large hemorrhage in the stomach, after which a gastrointestinal decompression tube was placed, so the bright red blood was drained. Subsequently, a sunken vascular malformation tissue in the anterior wall of the gastric fundus was observed under emergency endoscope. Pulsating blood flow appeared immediately after biopsy, and over-the-scope clip (OTSC) was quickly applied to stop the bleeding. Near the bleeding point, scar-like tissue that was surrounded by interrupted mucosa was discovered, and biopsy was performed at this site. DIAGNOSIS The diagnosis of DL and gastric MALT were determined by the digestive endoscopy and biopsy pathology. INTERVENTIONS With the diagnosis of DL and gastric MALT, the hemorrhagic spot was treated by OTSC. After the patient's condition was stable, anti-Helicobacter pylori treatment was performed. OUTCOMES After the corresponding treatment, the 6-month follow-up revealed that the lymphoma was not completely cured, but no further bleeding occurred. There was no bleeding in the epigastric region and the patient was in good condition. LESSONS From endoscopy, it is easy to miss DL. When the hemostatic equipment is fully prepared, biopsy can be performed. After biopsy, pulsatile bleeding is convincing evidence for Dieulafoy disease. OTSC represents an effective and low-risk method for DL and it could replace surgery. Moreover, the mucosa surrounding Dieulafoy disease should be carefully observed to exclude coexisting diseases such as lymphoma or gastric cancer.

Abstract
We describe the clinicopathologic and molecular features of 2 cases of gastric monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL), which were first diagnosed from gastric biopsies, one was primary whereas the other was gastric involvement by MEITL. Both cases were older men with stomach ulcers. Case 1 was admitted for a hemorrhage in the upper digestive tract and case 2 for edema. Histology of both cases showed infiltrated monomorphic and medium-sized lymphocytes with lymphoid epithelial phenomenon. An inflammatory background and vascular hyperplasia were also observed likely due to the ulceration. Neoplastic cells expressed CD2, CD3, CD7, CD8, CD56, TIA-1, and MYC, not CD5, CD4, Granzyme B, CD20, CD30, TdT, or EBER. Both lymphomas showed TCRG gene rearrangement and c-MYC gains. Moreover, we first affirmed polysomy of chromosome 8 in case 2. For correct diagnosis of this rare tumor at the rare location, it is important that pathologists raise the possibility and exclude other differential diagnoses.

Abstract
BACKGROUND Although the first-line therapy for early-stage gastric mucosa-associated lymphoid tissue lymphoma is the eradication of Helicobacter pylori, the effect of eradication in Helicobacter pylori-negative cases is unclear. In this case report, we describe a surgical option for a case of Barrett's esophageal cancer with concurrent gastric mucosa-associated lymphoid tissue lymphoma. CASE PRESENTATION A 79-year-old man was admitted to our hospital with Barrett's esophageal cancer and gastric mucosa-associated lymphoid tissue lymphoma. Initially, we performed endoscopic submucosal dissection for Barrett's esophageal cancer. Since residual tumor was observed after the endoscopic submucosal dissection, we performed an esophagectomy with two-field lymph node dissection, which was followed by placement of a gastric conduit via the posterior mediastinal route. He was discharged 14 days after surgery. Although no additional treatment exists for mucosa-associated lymphoid tissue lymphoma, no recurrent disease has been detected to date. CONCLUSION An option to use a portion of the stomach with low-grade malignant mucosa-associated lymphoid tissue lymphoma as a conduit after esophagectomy was suggested.

Abstract
The stomach is the most common primary site of an extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) type, which is characterized by an indolent clinical course. A diagnosis of gastric MALT lymphoma requires an endoscopic biopsy that should be confirmed by an experienced pathologist. Gastric MALT lymphoma shows a variable endoscopic appearance, including erosion, erythema, discoloration, atrophy, ulcer, and subepithelial lesion. The distribution is often multifocal. Therefore, clinical suspicion and multiple biopsies are essential for an accurate diagnosis. Gastric MALT lymphoma is almost invariably associated with a Helicobacter pylori (H. pylori) infection. H. pylori eradication therapy is the mainstay of treatment, which must be delivered to all patients regardless of the H. pylori infection status or stage. For patients who have failed to achieve remission following eradication therapy, radiotherapy or chemotherapy can be considered. Radiotherapy is an effective treatment modality for a localized stage and shows excellent outcomes. In the presence of disseminated or advanced disease, chemotherapy and/or immunotherapy with the anti-CD20 monoclonal antibody, rituximab, can be applied. Treatment should be individualized according to the stage and symptoms, as well as the patients' preference. Given that the clinical course of gastric MALT lymphoma is usually indolent, watchful waiting may be an adequate strategy in selected cases where scheduled follow-up is guaranteed.

Abstract
BACKGROUND Differential diagnosis between extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue and inflammatory bowel disease is mainly based on histopathologic evaluation of intestinal biopsies, although there is no single definitive diagnostic investigation and that circumstance can lead to misdiagnosis in particular cases. Herein we present a rare, ulcerative form of marginal zone lymphoma which mimics the Crohn’s disease (CD) of upper digestive tract.
CASE SUMMARY A 50-year-old man was presented with recurrent episodes of malaise and melena also weight loss. Enteroscopy of the small bowel demonstrated an ulcer in the jejunum. Microscopically, biopsies showed lymphoplasmacytic infiltrate. Diagnosis of CD was made. Primary treatment consisted of prednisone and azathioprine and was followed by azathioprine 100 mg per day with good clinical response in the following 2 years until relapse. At this time the results of endoscopic biopsies derived from proximal wall of stomach revealed Helicobacter pylori-negative marginal zone lymphoma of the gastric fundus. Immunophenotyping confirmed atypical CD20-positive cell population. Based on these biopsies, marginal zone lymphoma of mucosa-associated lymphoid tissue was diagnosed. Unfortunately, the contact with the patient was lost until one year later he was hospitalized with nausea, vomiting and severe pain because of gastrointestinal perforation. Four months later after laparotomy, the patient was treated with a course of chemotherapy. Complete remission was observed following 6 cycles of treatment.
CONCLUSION This case report highlights the clinical relevance of knowledge and awareness of marginal zone lymphoma simulating CD.

Abstract
Helicobacter pylori (H. pylori) is one of the most common human pathogens, affecting half of the world’s population. Approximately 20% of the infected patients develop gastric ulcers or neoplastic changes in the gastric stroma. An infection also leads to the progression of epithelial–mesenchymal transition within gastric tissue, increasing the probability of gastric cancer development. This paper aims to review the role of H. pylori and its virulence factors in epithelial–mesenchymal transition associated with malignant transformation within the gastric stroma. The reviewed factors included: CagA (cytotoxin-associated gene A) along with induction of cancer stem-cell properties and interaction with YAP (Yes-associated protein pathway), tumor necrosis factor α-inducing protein, Lpp20 lipoprotein, Afadin protein, penicillin-binding protein 1A, microRNA-29a-3p, programmed cell death protein 4, lysosomal-associated protein transmembrane 4β, cancer-associated fibroblasts, heparin-binding epidermal growth factor (HB-EGF), matrix metalloproteinase-7 (MMP-7), and cancer stem cells (CSCs). The review summarizes the most recent findings, providing insight into potential molecular targets and new treatment strategies for gastric cancer.

Abstract
A 79-year-old woman presented to the emergency department following a motor vehicle collision. As part of her workup she underwent a CT scan which identified a large mass containing calcifications centred around the gastric antrum, and while being assessed she produced 500 mL of haematemesis. An endoscopy revealed an area of friable mucosa the nature of which was uncertain, and multiple biopsies revealed amyloid deposition and active Helicobacter pylori gastritis. Following review of imaging and pathology, a diagnosis of gastric mucosa-associated lymphoid tissue (MALT) lymphoma was established. She was treated with quadruple therapy for the H. pylori and at 6-month follow-up she is asymptomatic with repeat endoscopy revealing healing of the ulceration and no biopsy evidence of H. pylori or MALT.

Abstract
Background Gastrointestinal (GI) lymphomas comprise a group of distinct clinicopathological entities of B- or T- cell type, with primary gastrointestinal Hodgkin lymphoma being extremely uncommon. The GI tract is the predominant site of extranodal non-Hodgkin lymphoma accounting for 30–40% of all extranodal lymphomas. In the Western world, the stomach is the most commonly involved site followed by the small bowel. Several chronic inflammatory and immune-mediated disorders which predispose to accelerated cell turnover may lead to the malignant transformation of gut lymphocytes and ultimately manifest as GI lymphoma. The challenge for the clinical gastroenterologist is that these tumors may have varied presentations, ranging from nonspecific symptoms such as dyspepsia or bloating to abdominal pain, nausea, vomiting, GI bleeding, diarrhea, weight loss or bowel obstruction. Objective We illustrate the range of presentations of GI lymphoma with examples based on consecutive cases evaluated at our institution over a 6-month period. These cases demonstrate how appropriately directed endoscopic evaluation with biopsies has the potential to provide a definitive diagnosis and allow the patient to proceed to definitive therapy. Conclusions The GI tract is the most commonly involved site for extranodal lymphoma with the stomach being most frequently involved organ. Chronic Helicobacter pylori infection, celiac disease, inflammatory bowel disease and autoimmune disorders may predispose to GI lymphoma. This heterogenous group of diseases has varied presentations that may mimic several other GI clinico-pathologic entities. GI lymphomas may be diagnosed with appropriately directed endoscopic evaluation coupled with generous tissue sampling and expert pathologic assessment. Management may range from antibiotic therapy, in the case of Helicobacter pylori-associated gastric MALT lymphoma, to chemotherapy with or without radiation and, in rare instances, surgery. There are presently no guidelines to direct endoscopic surveillance of GI lymphomas following treatment.

Abstract
Urinary collecting system rupture is an uncommon condition that usually occurs with symptoms of acute abdomen, secondary to peritoneal irritation by urine leaking. We report a case of a 49-year-old man admitted to our emergency department because of a worsening deep lower abdominal pain started 3 days before. The abdominal computed tomography revealed urine extravasation suggesting for urinoma. Because of patient pathological history of lymphoma, despite its apparent state of remission, he underwent a positron emission tomography - computed tomography with 18[F]-FDG and magnetic resonance in order to rule out a recurrence. Imaging supported the diagnostic hypothesis of a lymphatic recurrence that had compressed "ab-extrinseco" the urinary tract so much to break it. Based on our experience we can suggest that nontraumatic calyceal-pelvic rupture is an extremely rare manifestation of an onset of lymphoma.

Abstract
Marginal zone lymphomas represent approximately 10-12% of all B-cell lymphomas. Extranodal marginal zone lymphomas (EMZL) or mucosa-associated lymphoid tissue (MALT) lymphomas are the most common subtype. Almost half of all MALT lymphomas arise in the gastrointestinal (GI) tract and, while the stomach is the most common site of GI involvement, the small and large intestines can also be involved. Rare cases of MALT lymphoma involving the rectum have been reported; however, to our knowledge, involvement of the anal canal has never been reported in the literature. Here, we describe a unique case of MALT lymphoma of the anal canal. Infectious agents have been implicated in the pathogenesis of MALT lymphomas, possibly through persistent antigenic stimulation of the area; however, in our case no such infection was documented.

Abstract
The incidence of gastric mucosa-associated lymphoid tissue (MALT) lymphoma is increasing worldwide, but the diagnosis is difficult. Most patients are asymptomatic or complain of nonspecific gastrointestinal symptoms. As the endoscopic features of gastric MALT lymphoma are variable and nonspecific, the possibility of this condition may be overlooked during esophagogastroduodenoscopy, and it remain undiagnosed. Therefore, this condition needs to be considered when an abnormal mucosa is observed during this procedure. Biopsy performed during endoscopy is the primary diagnostic test, but false negative results are possible; large numbers of samples should be collected from both normal and abnormal mucosae. Endoscopic ultrasonography is useful to assess the depth of invasion and to predict the treatment response. After treatment, follow-up tests are required every 3 months until complete remission is achieved, and annually thereafter. Early diagnosis of gastric MALT lymphoma is difficult, and its diagnosis and follow-up require wide experience and competent endoscopic technique.

Abstract
Background/Aims The eradication of Helicobacter pylori (H. pylori) is an effective treatment in gastric mucosa-associated lymphoid tissue (MALT) lymphoma associated with H. pylori infection. However, the treatment strategy in gastric MALT lymphoma patients who are H. pylori-negative or unresponsive to H. pylori eradication therapy remains controversial. In this study, we investigated the clinical efficacy of treatments other than H. pylori eradication therapy in these groups of patients. Methods This was a retrospective single-center study based on the medical records of patients diagnosed with gastric MALT lymphoma at Yeungnam University Medical Center between January 2005 and December 2016. Patients were treated with H. pylori eradication therapy, chemotherapy, or radiotherapy according to their H. pylori infection status and stage of gastric MALT lymphoma. Results Of the 68 eligible patients, 50 were enrolled in the study. Of the 42 patients with H. pylori-positive gastric MALT lymphoma, 36 (81.7%) were treated with H. pylori eradication therapy as primary treatment and 25 (69.4%) achieved a complete response (CR). Patients without a CR after H. pylori eradication therapy (n=11, 30.6%) received radiotherapy as a secondary treatment. Two patients with H. pylori-positive gastric MALT lymphoma and eight with H. pylori-negative gastric MALT lymphoma received radiotherapy as the primary treatment. CR was achieved in all 21 patients treated with radiotherapy as primary or secondary treatment. The 5-year progression-free survival rate after radiotherapy was 92.9%. Conclusions Radiotherapy may be a worthwhile treatment option in patients with H. pylori-negative MALT lymphoma or H. pylori-positive MALT lymphoma that is not responsive to H. pylori eradication therapy.

Abstract
Primary gastric lymphoma (PGL) represents a rare pathology, which can be easily misdiagnosed because of unspecific symptoms of the digestive tract. Histologically, PGL can vary from indolent marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT) to aggressive diffuse large B-cell lymphoma (DLBCL). During the years, clinical trials revealed the important role of Helicobacter pylori (H. pylori) in the pathogenesis of gastric MALT lymphoma. Infection with Helicobacter pylori is an influential promoter of gastric lymphomagenesis initiation. Long-term studies revealed that eradication therapy could regress gastric lymphomas.

Abstract
BACKGROUND AND AIMS To evaluate the prevalence and the long-term course of gastric precancerous lesions in patients with GML. PATIENTS AND METHODS In this retrospective single-centre study, we included 179 patients with GML, 70 with gastric diffuse large B-cell lymphoma (GDLBCL) and 152 with Helicobacter pylori-associated gastritis (HpG), from January 1995 to January 2014. The presence of atrophic gastritis, intestinal metaplasia and neoplastic lesion has been assessed at baseline and during follow-up. RESULTS Atrophic gastritis was more frequent in the GML group whereas there was also a trend for intestinal metaplasia and gastric dysplasia. In patients with GML, atrophic gastritis, intestinal metaplasia and gastric dysplasia were more frequent in the GML area than in other part of the stomach. During follow-up, the prevalence of atrophic gastritis remained stable overtime whereas intestinal metaplasia and dysplasia tend to increase overtime. In multivariate analysis, the occurrence of dysplasia or carcinoma was associated with the presence of intestinal metaplasia at baseline and male gender. CONCLUSION GML is associated with gastric precancerous lesion to a higher extent than GDLBCL and HpG. Those precancerous lesions do not regress despite achievement of complete remission of GML and tend to increase overtime.
