A colonic mucosa-associated lymphoid-tissue (MALT) lymphoma is relatively rare compared to lymphomas of the stomach or small intestine. We present a case of a MALT lymphoma in the cecum and rectum found during screening colonoscopy. A 54-year-old female, who had undergone right-breast-conserving surgery with axillary dissection due to an invasive ductal carcinoma and a left-breast excisional biopsy due to microcalcification following adjuvant chemoradiation therapy 3 years earlier, was found to have 3-mm-sized smooth elevated lesions in both the cecum and rectum...

Extranodal mucosa associated lymphoid tissue (ENMALT) marginal zone lymphomas may arise at any site of the body. The most frequent localizations other than gastrointestinal and eye are salivary gland, skin, lung and thyroid. These lymphomas usually arise in a setting of inflammation due to a persistent infection or autoimmune diseases such as Sjogren syndrome in salivary MALT lymphomas and Hashimoto's thryroiditis in thyroid lymphomas. They affect middle-aged patients with a female predominance when lymphoma arises in certain locations...

Approximately 50% of patients with newly diagnosed marginal zone lymphoma (MZL) are of advanced age. For the three subtypes of MZL (extranodal MZL of mucosa-associated lymphoid tissue, splenic MZL, nodal MZL), the median age at diagnosis is around 65-70 years. Due to the lack of larger studies in MZL, little is known of the prevalence of comorbidity, polypharmacy, or geriatric syndromes in older patients with MZL. The impact of these concurrent conditions on the tolerability and feasibility of diagnostic or therapeutic procedures used in MZL has not been specifically investigated...

Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) occurs at diverse anatomic sites and is closely associated with several distinct chronic inflammatory disorders. Both the acquired genetic abnormalities and active chronic immunological responses play a critical role in the development of MALT lymphoma, interestingly by dysregulating similar molecular mechanisms. The three translocations seen in MALT lymphoma, namely t(14;18)(q32;q21)/IGH-MALT1, t(1;14)(p22;q32)/BCL10-IGH, and t(11;18)(q21;q21)/BIRC3 (API2)-MALT1 are capable of activating both canonical and non-canonical NF-κB pathways...

Extranodal marginal zone B-cell lymphomas of the mucosa associated lymphoid tissue (MALT) arise from lymphoid populations that are induced by chronic inflammation in extranodal sites. Among the MALT lymphomas, gastrointestinal (GIT) MALT lymphoma is the most frequent compared to non-GIT MALT lymphoma arising from other sites. Gastric MALT lymphoma has been the first to be described with the evidence of an etiopathogenetic link provided by the association between Helicobacter pylori-positive gastritis and gastric MALT lymphoma...

INTRODUCTION: Ocular adnexal lymphoproliferative disorders (OALDs) are almost exclusively of B-cell origin, with the majority being extra-nodal marginal zone lymphomas of mucosa-associated lymphoid tissue (MALT). The comparative efficacy of involved field radiation therapy (IFRT) in MALT vs. non-MALT OALDs is not known. MATERIALS AND METHODS: We present a single-center, large cohort, retrospective study of the efficacy of IFRT in OALDs. Failure-free survival (FFS), complete remission, and local, regional, and distant failure were determined for 112 patients with MALT OALDs (n = 71) and non-MALT OALDs (n = 41) cohorts...

A broad spectrum of diseases are associated with IgM monoclonal gammopathy, including Waldenstrom macroglobulinemia (WM), various types of B cell non-Hodgkin's lymphoma (NHL), multiple myeloma (MM), primary amyloidosis (AL), and monoclonal gammopathy of undetermined significance (MGUS); these are called IgM monoclonal gammopathy related diseases (IgM-RD). We investigated MYD88 L265P and WHIM-like CXCR4 mutations in various IgM-RD. Patients with serum immunofixation electrophoresis confirmed IgM monoclonal gammopathy who had enough material for DNA extraction and presented between January 2008 and October 2016 at Peking Union Medical College Hospital were enrolled in this cohort...

The detection rate of fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) in extragastric mucosa associated lymphoid tissue (MALT) lymphoma is under debate and the reason is not clear. Our aim was to investigate the metabolic behavior of extragastric MALT lymphoma and whether the histological features (Ki-67 index and plasmacytic differentiation, PD) might explain it. PET/CT images were analyzed visually and semi-quantitatively and compared with Ki-67 index and PD...

Epstein-Barr virus (EBV) is a well-documented etiologic factor for multiple sclerosis (MS). EBV encodes at least 44 microRNAs (miRNAs) that are readily detectable in the circulation of human. Previous studies have demonstrated that EBV-encoded miRNAs regulate host immune response and may serve as biomarkers for EBV-associated diseases. However, the roles of EBV miRNAs in MS are still unkown. To fill the gap, we conducted a comprehensive profiling of 44 mature EBV miRNAs in 30 relapse-remitting MS (RRMS) patients at relapse and 30 matched healthy controls...

The rectal tonsil is a rare polypoid lesion exclusively found in the rectum and is considered a reactive proliferation of the lymphoid tissue. Although this lesion is benign, we recommend that it should be differentiated from carcinoid or polypoid type of mucosaassociated lymphoid tissue (MALT) lymphomas, based on gross findings. In this case report, we describe a case of rectal lesions with a unique appearance in a 41-year-old man. Colonoscopy revealed two 5-mm-sized nodules located opposite from each other on the left and right sides of the lower rectum...

Mucosa-associated lymphoid tissue (MALT) lymphoma of the liver is a very rare condition and thus the diagnosis may be challenging. The clinical presentation is usually variable, ranging from minimal clinical symptoms to severe end stage liver disease. In this paper, we describe the clinicopathologic findings in two cases of primary hepatic MALT lymphoma. One case is an 80-year-old female with no underlying chronic liver disease and the second case is a 30-year-old female with autoimmune hepatitis complicated by MALT lymphoma...

Mucosa-associated lymphoid tissue (MALT) lymphoma usually originates from the stomach and presents with low (18)F-fluorodeoxyglucose (FDG) avidity with average maximum standard uptake value of 3.6. Colorectal MALT lymphoma is a rare entity that contributes to 1.6% of all MALT lymphomas and < 0.2% of large intestinal malignancies. The case reported herein firstly revealed stage IIE MALT lymphoma with unexpected higher (18)F-FDG avidity of 18.9 arising at the colorectal anastomosis in a patient with a surgical history for sigmoid adenocarcinoma, which was strongly suspected as local recurrence before histopathological and immunohistochemical examinations...

Purpose: To determine the optimal radiotherapy technique for gastric mucosa-associated lymphoid tissue lymphoma (MALToma), we compared the dosimetric parameters and the risk of solid secondary cancer from scattered doses among anterior-posterior/ posterior-anterior parallel-opposed fields (AP/PA), anterior, posterior, right, and left lateral fields (4_field), 3-dimensional conformal radiotherapy (3D-CRT) using noncoplanar beams, and intensity-modulated radiotherapy composed of 7 coplanar beams (IMRT_co) and 7 coplanar and noncoplanar beams (IMRT_non)...

Gastric colonization with Helicobacter pylori induces diverse human pathological conditions, including superficial gastritis, peptic ulcer disease, mucosa-associated lymphoid tissue (MALT) lymphoma, and gastric adenocarcinoma and its precursors. The treatment of these conditions often relies on the eradication of H. pylori, an intervention that is increasingly difficult to achieve and that does not prevent disease progression in some contexts. There is, therefore, a pressing need to develop new experimental models of H...

BACKGROUND: Mucosa-associated lymphoid tissue lymphomas can occur in various parts of the body, and half of mucosa-associated lymphoid tissue lymphomas occur in the gastrointestinal tract. Gastric mucosa-associated lymphoid tissue lymphoma is the most common lymphoma of the gastrointestinal tract and primary rectal mucosa-associated lymphoid tissue lymphoma is very rare. Because of the high radiosensitivity of mucosa-associated lymphoid tissue lymphomas, this condition can be controlled with radiotherapy of approximately 30 Gy alone...
