Pigment changes observed objectively in association with psoriasis and as a result of its treatment are discussed. These and other symptom associations (vitiligo, albinism) mainly located at leukodermic sites were made the basis of a histochemical study of melaninogenesis in psoriasis. The DOPA reaction and metal impregnations showed certain qualitative and possibly site changes on the part of cell elements that further histochemical reactions (demonstration of ATPase activity, metachromatic staining with toluidine blue) appear to classify as melanocytes. Such changes were related to the evolution or posttreatment course of a psoriatic patch.
