S1 guideline sweat gland carcinoma

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, Volume 24, Issue 9, Page e1356-e1385, September 2026.
Summary The current classification of sweat gland carcinomas is based on histomorphological characteristics and distinguishes between more than 20 entities. Most patients are older, but some subtypes also affect middle‐aged and younger patients. The majority of tumors arise de novo. Sweat gland carcinomas have nonspecific clinical features.

Association of high organochlorine pesticide serum levels with oxidative stress in intestinal metaplasia and gastric cancer

Heliyon
It has been revealed that certain organochlorine pesticides may increase the risk of gastric cancer incidence among farm workers. This research aimed to assay levels of 7 different organochlorine pesticides in the serum of functional dyspepsia ...

Population‐Level Trends in Gastric Cancer Mortality and Incidence After Expansion of Japanese National Health Insurance Coverage for Helicobacter pylori Eradication: A Descriptive Time‐Trend Study

Helicobacter, Volume 31, Issue 5, September/October 2026.
ABSTRACT Background In February 2013, Japanese national health insurance coverage for Helicobacter pylori eradication was expanded to patients with H. pylori‐positive, endoscopically diagnosed chronic gastritis. This policy broadened access to eradication treatment, but its relationship with subsequent population‐level gastric cancer trends requires ...

Unveiling the molecular profile of adenosquamous gallbladder carcinoma: characterization of a Caucasian cohort

Histopathology, Volume 89, Issue 3, Page 442-455, September 2026.
GBASCs are MMRp tumours, exhibiting minimal HER2 overexpression and elevated PD‐L1 expression compared to adenocarcinomas. Especially in metastatic and TP53‐wild type tumours, GBASCs can express CLDN18, albeit limited to the glandular component. Their genomic profile resembles that of adenocarcinomas with an enrichment in alterations on PIK3CA, PTEN ...

When to consider an inborn error of immunity: clues for physicians

Internal Medicine Journal, Volume 56, Issue 9, Page 1488-1499, September 2026.
Abstract The term inborn errors of immunity (IEIs) refers to the rapidly expanding group of genetic disorders causing dysregulation of the immune system. With improved genetic testing in recent years, the number of defined IEIs and their range of phenotypic presentations has grown vastly, with more than 550 IEIs now described.
