[Skin manifestations observed during treatment with penicillamine and its derivatives].

Many forms of toxidermia are observed during D-penicillamine therapy. The exact type seems to depend on the pathology for which the drug was prescribed; pemphigus during rheumatoid arthritis, perforating serpiginous elastoma in Wilson's disease, cystinuria... The two physiopathogenic mechanisms discussed, an autoimmune reaction and a direct action of D-penicillamine on the skin, would seem to be complementary.
