Abstract
- The authors reviewed two patients showing "vitiligo-like depigmentations" where the skin had been in close contact with a metal spectacle frame made of nickel alloy. In spite of the hypersensitivity to nickel in both patients, they showed clinical and histologic findings indicate that the formation of "vitiligo-like depigmentation" does not result from posinflammatory hypopigmentation but from chemical hypomelanosis. We could not explain the underlying mechanisms; however, the speculation that the "vitiligo-like depigmentation" may come from the direct effect of the nickel itself, prompted us to report these cases.
