ABSTRACT Pleural mesothelioma (PM) is a rare and aggressive cancer arising from pleural mesothelial cells with a strong association to asbestos exposure. Among the diagnostic strategies available are noninvasive techniques including thoracic ultrasound (TUS), computed tomography (CT) scans, positron emission tomography (PET‐CT), and invasive procedures such as thoracoscopy and pleural biopsy. Accurate identification of the histological subtype is critical for tailoring treatment strategies. The standard treatment for unresectable PM has traditionally been chemotherapy, particularly platinum and pemetrexed. However, recent advances in translational clinical research, including immune checkpoint inhibitors (ICIs), are changing the therapeutic landscape, offering new opportunities for personalized treatment. The recent FDA approval of nivolumab and ipilimumab combination therapy as a first‐line treatment has significantly improved outcomes, especially for nonepithelioid subtypes. Ongoing studies are exploring additional immune‐targeted therapies such as VISTA, LAG‐3, and dendritic cell‐based therapies. Early detection, refined biomarker identification, and a deeper understanding of the tumor microenvironment remain essential to improving PM prognosis and patient survival. This review provides a comprehensive exploration of the epidemiology, etiology, clinical manifestations, diagnostic approaches (including immunohistochemical and molecular markers), staging, and current treatment strategies for PM.
