title: [Is psoriasis an autoimmunologic disease?].
abstract: DThe defective function of T-lymphocytes, which is a finding in active psoriasis, is transitional and reversible, whereas the immunological mechanism is mainly related to the formation of immune complexes consisting of stratum corneum antibodies and stratum corneum antigen, which through binding of complement and activation of chemotactic complement components is responsible for the phenomenon of "squirting papillae". The earliest lesions preceding pin point papules, called pre-pin-point papules, were induced by stripping or developed spontaneously in a marked field closely observed for several days. In the changes preceding earliest psoriatic lesions. Abundant polymorphonuclear infiltrates are present, and polymorphs seem to play an important role in a selfperpetuating of disease process. The therapeutic implications of the immunologic studies in psoriasis are: either depletion of activated polymorphs (eg. continuous peritoneal dialysis) and/or removal of the factors responsible for their activation (eg. treatment of focal infections) or external use of the drugs affecting the antigenicity of stratum corneum (tars), or inhibition of exocytosis (a probable mechanism of puva).
