psoriasis vulgaris. treated psoriasis vulgaris. the previously existing typical psoriatic plaques are replaced by red spots with marginal hyperpigmentation. the treatment was carried out locally with dithranol [cignolin]. scaling no longer present. the brewing discoloration of the lesional surroundings are reversible discolorations of the nromal skin by diathranol. the diagnosis "psoriasis" is doubtless due to the known anamnesis.
