has been classified as a class I carcinogen by WHO because of its primary involvement in the development of gastric cancer and mucosa-associated lymphoid tissue (MALT) lymphoma. This review focuses on understanding the molecular pathophysiological mechanisms that operate within intracellular transduction pathways and their relevance in the treatment strategies for the two main diseases caused by virulence factors such as cytotoxin-associated gene A and vacuolating cytotoxin A genotypes, inflammatory mediators, -induced microRNA deregulation, alterations in autophagy proteins and regulators, and changes in DNA methylation are some of the molecular mechanisms that play essential roles in infection and gastric carcinogenesis. The discovery of novel treatment strategies that target the deregulated intracellular transduction pathways in gastric carcinogenesis and MALT lymphoma is critical. eradication (HPE) is not limited to -dependent low-grade MALT lymphoma and may be used in patients with high-grade diffuse large B-cell lymphoma (DLBCL) (de novo or DLBCL-MALT lymphoma). The loss of dependency and high-grade transformation appear to be distinct events in the progression of gastric lymphoma. Interestingly, patients with positive gastric DLBCL without histological evidence of MALT lymphoma (pure gastric DLBCL) may respond to HPE therapy.

Background: Lymphoma is a common hematological malignancy with diverse morphological and immunophenotypic characteristics that may affect treatment and outcomes. Thus, accurate differential diagnosis is crucial, and molecular genetic testing is valuable. We aimed to investigate the genetic characteristics of Korean patients with lymphoma using a next-generation sequencing (NGS)-based targeted panel.

Adenoid cystic carcinoma (AdCC) of the breast is a rare histological subtype of breast cancer, which usually has a low propensity for metastasis and is associated with a good prognosis. AdCC metastasis to the kidney is rare, with only 29 cases reported in the literature. We report a case of a woman in her 60s with multiple right-sided large cystic-solid renal lesions after a recent diagnosis of marginal zone B-cell lymphoma.

Background: Acquired angioedema due to C1-inhibitor deficiency (AAE-C1-INH) is very rare compared to its prototype, hereditary angioedema. An updated characterisation of the AAE-C1-INH cohort in UK is required to inform management.
Objectives: To describe the disease burden of AAE-C1-INH, long-term prophylaxis (LTP) and the clinical, immunochemical and treatment profiles of AAE-associated diseases in UK.
Introduction: Anal Lymphoma (AL) is a rare presentation of extranodal lymphomas, characterized by occurrence in the anal area and largely understudied due to its infrequency. This study aims to address gaps in knowledge about AL's demographic and clinical profiles, treatments, and survival outcomes, leveraging data from the SEER program.
Methods: We conducted a retrospective analysis of 79 AL cases identified in the SEER database from 2000 to 2022; 36 stage I AL were identified and defined as localized primary anal lymphoma (L-PAL).
