NCIt definition : A malignant neoplasm that arises from mesothelial cells in the pleura and shows a
diffuse growth pattern. It arises on the parietal and sometimes visceral pleura as
multiple small nodules that later become confluent and invade the chest wall adipose
tissue and muscle. Asbestos exposure is the main cause for the development of pleural
malignant mesothelioma. It usually affects patients over sixty years of age. The latency
period is long. Patients usually present with pleural effusion, dyspnea and chest
wall pain. Additional signs and symptoms include chills, sweating, weight loss, and
weakness. Morphologic variants include epithelioid, desmoplastic, sarcomatoid, and
biphasic mesothelioma. The clinical course is usually aggressive.;
