Cellular Plasticity in Malignant Transformation: Mesothelial Cells
Pathobiology 2026 April 29 [Link] Claire W Michael, Ben Davidson Abstract Background: Mesothelial proliferations range from reactive lesions to benign and malignant tumors, bearing witness to the plasticity of these cells. Their diagnosis often requires combination of morphological assessment, immunohistochemistry, and molecular testing. Summary: Considerable progress has been made in recent years in all the…

Read MoreCheckpoint kinase 1 protein as a diagnostic marker for pleural mesothelioma
Journal of the American society of Cytopathology 2026 March 28 [Link] Azadeh Asghari Birbaneh, Christos Meristoudis, Caspar Bundgaard Nielsen, Weronika Maria Szejniuk, Morten Johansen, Peter Derek Christian Leutscher, Vasiliki Panou, Oluf Dimitri Røe Abstract Introduction: Pleural mesothelioma (PM) is an aggressive malignancy that poses diagnostic challenges, particularly in cytological specimens. Checkpoint kinase 1 (CHK1); a…
Read MoreGene expression and immunohistochemical phenotypes of high-grade epithelioid mesothelioma
Human Pathology 2026 July [Link] Marie-France Gagnon, Krasimira Rozenova, Chien Lu, Carlos Sosa, Beth Pitel, Matthew Petersen, Sydney Clausen, Anja C Roden, Kevin C Halling, Ying-Chun Lo Abstract Grading of epithelioid mesothelioma (EM) has recently been reported to be predictive of survival. We investigated whether RNA expression profiles and immunohistochemical (IHC) markers could refine EG…
Read MoreUpdate on pleural epithelioid mesothelioma: New insights for diagnosis and patient management
Journal of Thoracic Oncology 2026 April 8 [Link] Francoise Galateau Sallé, Mary Beth Beasley, Luka Brcic, Wendy Cooper 4, Sanja Dacic, Marc de Perrot, Ming-Sound Tsao, Sonja Klebe, Andrew Churg, Aaron S Mansfield, Paul Baas Abstract Diffuse Mesothelioma is typically diagnosed through histopathologic evaluation. Recent advances in therapeutic strategies have heightened the importance of accurate…
Read MoreThe Importance of 5-hmC Expression Loss in Diagnosis of Mesothelioma and the Relationship Between TROP2 Expression and Histomorphological Parameters in Mesotheliomas
International Journal of Surgical Pathology 2026 April 6 [Link] Hale Kivrak, İlke Evrim Secinti, Egemen Akincioglu, Elcin Kadan, Ertugrul Celik, Gulcin Guler Simsek Abstract Objectives: Mesothelioma is an aggressive cancer that is often not suitable for curative surgery. It can be difficult to distinguish from reactive processes and other malignancies, especially in small biopsies, and outcomes of systemic therapies remain…
Read MoreClinical, diagnostic and prognostic relevance of GATA3 in malignant pleural mesothelioma: a retrospective cohort study
BMC Cancer 2026 April 2 [Link] Alejandro Avilés-Salas, David Dávila Dupont, Alejandro Aranda-Gutierrez, Andrea Nallely Heredia-Jara, Enrique Caballé-Perez, Luis Cabrera-Miranda, Andrés F Cardona, José Lucio-Lozada, Cesar Castillo-Ruiz, Norma Hernandez-Pedro, Luis Corrales, Claudio Martin, Oscar Arrieta Abstract Background: Malignant pleural mesothelioma (MPM) is an aggressive malignancy with a poor prognosis and limited treatment options. Recently, GATA3 has emerged as a useful adjunct immunohistochemical marker, especially for non-epithelioid subtypes. Although…

Oncology Letters 2026 March 4 [Link] Yuanchen Lu, Junjun Miu, Zhongru Fan, Zheng Zhi, Lei He, Junpeng Deng, Xianhua Shao, Jingqi Hua, Yichen Qian, Jianjun Xie Abstract Malignant mesothelioma of the tunica vaginalis testis (MMTVT) is a rare pathological entity. The present report describes the case of a patient who presented with insidious-onset right lower…
Read MoreMoving Beyond Morphology: Toward a Morpho-Molecular Classification of Pleural Mesothelioma
Journal of Thoracic Oncology 2026 February 20 [Link] Gabrielle Drevet, Lipika Kalson, Laurane Mangé, Francoise Galateau-Salle, Arnaud Scherpereel, Lara Chalabreysse, Julien Mazières, Luka Brcic, Nicolas Alcala, Jean-Michel Maury, Lynnette Fernandez-Cuesta, Matthieu Foll Abstract Despite recent advances in the treatment of pleural mesothelioma, it remains a challenging and heterogeneous disease, with limited options for patients. Survival…
Read MorePleural Fluid Cytology-Histology Correlation in Patients With Malignant Pleural Mesothelioma: A Series of 26 Cases
Cytopathology 2026 February 20 [Link] John Findley, Matthew Demetrious, Lucas Yan, Lei Yan Abstract Background: To understand the efficacy of pleural effusion cytology in the diagnosis of malignant mesothelioma, we conducted this retrospective study to review the pleural fluid cytologies of patients diagnosed on concurrent/recent pleural biopsy histology. The clinicopathologic features and common cytomorphology were…
