The differential diagnosis in cellular effusions with cytological atypia often includes
malignant mesothelioma (MM), reactive mesothelial proliferation, and malignancies of …

BACKGROUND Fine‐needle aspiration cytology (FNAC) of serous membrane effusions may
fulfil a challenging role in the diagnostic analysis of both primary and metastatic disease …

Background Guidelines for gastric and gastroesophageal (GE) cancer recommend staging
laparoscopy (SL) with peritoneal cytology (PC). However, the reliability of PC is unknown …

Introduction Lung adenocarcinoma (LADC) is the most common occult primary in patients
presenting with a malignant pleural effusion. Distinguishing metastatic LADC from reactive …

Background Claudin‐4, a tight junction associated protein expressed in epithelial cells, is
purported as a highly specific and sensitive marker for epithelial malignancies. Our aim was …

Background Recently, claudin‐4 (CL4) immunocytochemistry was reported to be useful for
differential diagnosis in effusion cytology. We wondered whether CL4 might be useful for …

Background The cytological analysis of peritoneal effusions serves as a diagnostic and
prognostic aid for either primary or metastatic diseases. Among the different cytological …

The objective of this study was to analyze the expression and prognostic role of the tight
junction protein claudin-10 in high-grade serous carcinoma (HGSC). Claudin-10 protein …

Abstract Objective: Claudin-3 and claudin-4 have recently been reported as promising
targets for the detection and diagnosis of cancer. This study was designed to evaluate the …

Definitive cytopathological interpretation of some of the effusion fluids may not be possible
based on cytomorphological evaluation alone. As discussed in other reviews, this is due to …
