title: Parkinson's disease, macular degeneration and cutaneous signs of mercury toxicity.
abstract: OBJECTIVE
  The objective of this study was to determined if there was a relationship between Grover's disease and Parkinson disease.
  
  
  METHODS
  Fourteen patients with Parkinson disease and 14 control patients were randomly selected and examined for cutaneous eruptions and blood mercury levels.
  
  
  RESULTS
  Of the 14 patients with Parkinson's disease, 13 had Grover's disease and detectable blood mercury. None of the patients in the control group had a cutaneous eruption and only 2of the 14 had detectable blood mercury.
  
  
  CONCLUSIONS
  Mercury may play a role in the etiology of Parkinson disease and Grover's disease.
