Multiple tumours of different histological type of the salivary glands are extremely rare. Here we report a 72-year-old woman who was diagnosed with simultaneously occurring Warthin's tumour of the left parotid and mixed tumour of the homolateral submandibular gland. To our knowledge this combination of histology and localization has not been reported previously. This case also illustrates the importance of thorough examination even after the identification of a single tumour, as multiple synchronous primary tumours--even if rare--can be a diagnostic possibility.

Beyond Metaplasia: Unraveling the Complex Pathogenesis of Autoimmune Atrophic Gastritis and Its Implications for Gastric Cancer Risk.

Autoimmune gastritis (AIG) is a chronic inflammatory condition characterized by immune-mediated destruction of gastric parietal cells, leading to oxyntic atrophy, achlorhydria, and hypergastrinemia. While AIG was historically linked to gastric adenocarcinoma and type I neuroendocrine tumors (NETs), recent evidence suggests the risk of adenocarcinoma in AIG is lower than previously believed, particularly in Helicobacter pylori (H. pylori)-negative patients.

Department of Dermatology, The Affiliated Hospital to Changchun University of Chinese Medicine, China.
Background: The skin, with its robust structural integrity and advanced immune defense system, serves as a critical protective barrier against environmental toxins and carcinogenic compounds. Despite this, it remains vulnerable to the harmful effects of certain hazardous agents.
Objectives: This study aimed to investigate the chemopreventive potential of β-caryophyllene (BCP) in mitigating 7,12-dimethylbenz[a]anthracene (DMBA)-induced skin carcinogenesis, focusing on the modulation of apoptosis and PI3K/AKT signaling pathways.
Usage of Milan System in Risk Stratification of Submandibular Gland Fine Needle Aspiration Cytology.
Laryngoscope
January 2025
Department of Otorhinolaryngology, Tan Tock Seng Hospital, Singapore, Singapore.
Objectives: The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) categorizes fine needle aspiration and cytology (FNAC) results into 6 tiers and assigns a risk of malignancy (ROM) to each category. Its utility in submandibular gland lesions remains unclear. Our article aims to study (1) the utility of the MSRSGC in classifying FNAC of submandibular gland masses, (2) describe the demographics and incidence of submandibular gland malignancy in our population, and (3) analyze the accuracy of FNAC in diagnosis of benign and malignant submandibular gland tumors.

Cytokines and NO Synthases Team, LBCM, FSB, USTHB, BP 32 El Alia, Bab Ezzouar, Algiers, 16111, Algeria.
Purpose: Since extract of the laminated layer (LL) from E. granulosus showed immuno-modulatory effects in vitro and in vivo, we sought to determine its effect on the onset, development, and evolution of experimental auto-immune uveitis (EAU). The latter is a model of some human diseases with ocular inflammation that can cause blindness.

Cases for a disease can be defined broadly using diagnostic codes, or narrowly using gold-standard confirmation that often is not available in large administrative datasets. These different definitions can have significant impacts on the results and conclusions of studies. We conducted this study to assess how using melanoma phecodes versus histologic confirmation for invasive or in situ melanoma impacts the results of a genome-wide association study (GWAS) using the Million Veteran Program.
