[Antipsoriatic effect of (tape) occlusion].

Occlusive dressing may lead to a significant reduction of the induration and desquamation of psoriatic lesions. Our lectin-histochemical findings suggest that this effect is unlikely to be caused by a normalization of abnormal keratinocyte differentiation. Since epidermal cells rich in calmodulin can immunohistologically be detected, we conclude that the egress from the stratum basale is at least partially inhibited.
