Malignant Mesothelioma

  • Malignant mesothelioma represents a neoplasia of the pleural mesothelial cells. The malignancy spreads by localized growth or seeding of the pleural surfaces such that large parts or the entire lung can become encased in a gooey-to-firm sheath of yellowish tumor cells. The disease is very rare but most individuals have a history of asbestos exposure, although interestingly there is no increased incidence with smoking. There is a significant lag between exposure and disease development, which can be longer 20 years.
