Non-Asbestos-related Malignant Pleural Mesothelioma

Abstract

Malignant pleural mesothelioma (MPM) is an uncommon tumor derived from mesothelial lining cells. MPM has been described as an insidious neoplasm because of its long latency period. The tumor is typically found in patients several decades after asbestos exposure. We herein describe a 26-year-old patient with MPM who presented with pleural effusion. The patient had not been exposed to asbestos or erionite. There are few case reports of non-asbestos-related MPM in young patients. We report this case to remind physicians to consider MPM in the differential diagnosis of pleural effusion in young patients without exposure to asbestos or erionitis.
