title: Arsenic in Dermatology.
abstract: BACKGROUND
  Arsenic is a chemical carcinogen that exists naturally and in the workplace.
  
  
  OBJECTIVE
  Review exposure, clinical signs of arsenic exposure, and the carcinogenic potential.
  
  
  METHODS
  Review of literature.
  
  
  RESULTS
  Arsenic is a known carcinogen that occurs both naturally and in the workplace. It causes cutaneous malignancies, hyperpigmentation, palmer and plantar keratosis, and internal malignancies, especially of the lung and bladder.
  
  
  CONCLUSIONS
  Exposure risks need to be well publicized. Those people with known exposure need regular full skin exams as well as close follow-up by their primary care physician.
