It has been shown that t(14;18)(q32;q21) involving fusion of IGH with MALT1 occurs frequently in mucosa-associated lymphoid tissue (MALT) lymphomas. Results of the present study indicate that the classical form of t(14;18)(q32;q21) involving fusion of IGH with bcl-2 can be detectable in a subset of MALT lymphomas in patients with hepatitis C virus (HCV) infection.

Introduction: There is little information in the literature on the early, sub-clinical stage and laboratory test results in patients with primary mucosa-associated lymphoid tissue (MALT) lymphoma of the lung, a rare disease.
Case Description: In a 75-year-old man, an open lung biopsy-confirmed diagnosis of primary pulmonary lymphoma was preceded by almost six months of anaemia of inflammatory disease and monocytosis without any pulmonary symptoms. When he developed a dry cough, increasing dyspnoea and marked weight loss, these changes deepened and became associated with reactive thrombocytosis; markedly increased ferritin and C-reactive protein (positive acute-phase reactants), as well as reduced albumin and transferrin (negative acute-phase reactants).

Sex hormones regulate gut function and mucosal immunity; however, their specific effects on the mucosa-associated lymphoid tissue (MALT) in the rectum of mammals remain unclear. Here, we aimed to investigate the influence of sex on MALT in the rectum of mammals by focusing on the rectal mucosa-associated lymphoid tissues (RMALTs) of C57BL/6NCrSIc mice. Histological analysis revealed that RMALTs were predominantly located in the lamina propria and submucosa of the rectal mucosa, with a significant sex-related difference in the distance from the anorectal junction to the first appearance of the RMALT.

The mucosal immune system, as the most extensive peripheral immune network, serves as the frontline defense against a myriad of microbial and dietary antigens. It is crucial in preventing pathogen invasion and establishing immune tolerance. A comprehensive understanding of mucosal immunity is essential for developing treatments that can effectively target diseases at their entry points, thereby minimizing the overall impact on the body.

Background: Ulcerative colitis is a chronic inflammatory bowel disease of the colon mucosa associated with a higher risk of colorectal cancer.
Objective: This study classified hematoxylin and eosin (H&E) histological images of ulcerative colitis, normal colon, and colorectal cancer using artificial intelligence (deep learning).
Methods: A convolutional neural network (CNN) was designed and trained to classify the three types of diagnosis, including 35 cases of ulcerative colitis (n = 9281 patches), 21 colon control (n = 12,246), and 18 colorectal cancer (n = 63,725).

Article Synopsis
- Mucosa-Associated Lymphoid Tissue (MALT) lymphoma, particularly gastric MALToma, is often associated with Helicobacter pylori (H. pylori) infection, though a significant number of cases occur without it.
- A study analyzed 52 patients with gastric MALToma from 2000 to 2021, finding that 48.1% were H. pylori-negative (HPN) and noted trends of increased HPN diagnoses in more recent years.
- Treatment outcomes showed that HPP patients had better responses to eradication therapy compared to HPN patients, who were more likely to receive additional chemo or radiotherapy.
- Despite these differences in treatment response, clinical features between HPP and HPN patients
