When the Diagnosis of Mesothelioma Challenges Textbooks and Guidelines.

J Clin Med 2021 May 30;10(11). Epub 2021 May 30.

Department of Thoracic Surgery, Faculty of Medicine, University Cattolica del Sacro Cuore, 20123 Rome, Italy.

The diagnosis of malignant mesothelioma (MPM) does not pose difficulties when presenting with usual clinico-radiologic features and morphology. Pathology textbooks and national/international guidelines generally describe the findings of classic MPM, underlining common clinical presentation, the gold standard of sampling techniques, usual morphologic variants, immunohistochemical results of several positive and negative primary antibodies in the differential diagnosis, and the role of novel molecular markers. Nevertheless, MPM often does not follow the golden rules in routine practice, while the literature generally does not sufficiently emphasize unusual features of its manifestation. Read More
