DefinitionThis section has been translated automatically.
The leucoderma psoriaticum first described by Rille is always linked to the location of psoriatic lesions that are in the process of regression or are already involved.
Leucoderma (or pseudoleucoderma) psoriatica spurium, on the other hand, is a color contrast formation. It occurs during cignolin (formerly also chrysarobin) therapy of psoriasis vulgaris. The desquamation of the psoriatic lesion leads to a lack of adhesion of cignolin or its brown oxidation products in the psoriatic lesion, so that only the healthy environment and not the psoriatic lesion is discolored brown.

Not necessary; spontaneous regression within 5-10 days.
