A case history published in the New England Journal of Medicine examining the case of a 37-year-old asbestos worker who was admitted to the Massachusetts General Hospital with cough and chest pain. An anatomical diagnosis was made of mesothelioma of the pleura and pericardium caused by workplace asbestos exposure. Although the physicians involved in the case believed that cancers of the mesothelium were impossible, their examination of the patient in this case caused them to conclude otherwise.
