title: A case of occupational peritoneal mesothelioma from exposure to tremolite-free chrysotile in Quebec, Canada: A black swan case.
abstract: BACKGROUND
  Tremolite contamination has been proposed as the cause of mesothelioma in workers exposed to commercial chrysotile. The asbestos industry and scientists it has sponsored, for example, have argued that commercial chrysotile does not cause peritoneal mesothelioma.
  
  
  METHODS
  Case report of peritoneal mesothelioma in a mill worker from a tremolite free Canadian mine.
  
  
  RESULTS
  Reports from pathology and occupational health and safety panels conclude that this mill worker developed work-related peritoneal mesothelioma.
  
  
  CONCLUSIONS
  Chrysotile without tremolite can cause peritoneal mesothelioma.
