Claudin‐18 expression in gastric type adenocarcinoma and HPV‐associated adenocarcinoma of the uterine cervix

Histopathology, EarlyView.
CLDN18 (43‐14A) is expressed in most gastric type adenocarcinomas and a much smaller proportion of HPV‐associated adenocarcinomas. Expression of CLDN18.2 mRNA but not CLDN18.1 mRNA is confirmed in both gastric type adenocarcinomas and HPV‐associated adenocarcinomas.

Optimized workup of lymph nodes in regard to UICC classification of colorectal carcinoma

Histopathology, EarlyView.
Treatment and outcome of colon cancer depend significantly on the histopathological examination of lymph nodes. Methodologically, stepwise sectioning and immunohistochemistry are the primary methods used. The extent of this examination is subject to debate but should be maintained at an adequate level in routine laboratory work.

The spectrum of breast in situ papillary carcinomas with invasion and invasive breast carcinomas with papillary features: an overview of histological subtypes and diagnostic challenges

Histopathology, EarlyView.
Invasive breast carcinomas with papillary features (IBCP) comprise diverse subtypes with variable architecture, histopathology, and clinical behaviour. This review outlines evolving classification, diagnostic criteria, and treatment implications, highlighting challenges in distinguishing in situ from invasive lesions. Standardised diagnostic approaches

Aquaporin‐1 differentiates intrahepatic cholangiocarcinoma from liver metastases of pancreatic ductal adenocarcinoma

Histopathology, EarlyView.
Differentiating intrahepatic CCA from PDAC metastatic to the liver is critical for the clinical management of patients with pancreatobiliary cancers. AQP1 has demonstrated an excellent discriminatory performance in this clinical scenario. Aims Differentiating intrahepatic cholangiocarcinoma (iCCA) from metastatic ductal adenocarcinoma of the pancreas ...
