[Iatrogenic chromodermatoses].

Generalized hyperpigmentation may be caused by internal diseases, by occasional or occupational intoxications, and by a group of drugs. Seven cases occurring after treatment with amiodarone (Cordarone) are reported, together with one case of argyria and one of mercury poisoning. Several of these cases were initially mistaken for cyanotic heart disease. Silver intoxication may occur after indiscriminate use of currently available silver-containing drugs. It may become even more frequent as a result of antismoking preparations.
