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.
Conclusion: Mercury may play a role in the etiology of Parkinson disease and Grover's disease.
