[About the regression of psoriasis capitis after mechanical epilation (relations between the psoriatic efflorescence and the follicular proliferation) (author's transl)].

The pathomorphological and pathophysiological reactions of the spontaneous and artificially induced skincycle in psoriasis capitis-lesions were clinically and histologically investigated. 1. After the epilation in the psoriasis capitis-lesion a healing of the psoriatic efflorescence was observed. 2. Histologically a close correlation between the induced anagen and the regression of the psoriasis existed: As a cause of this phenomenon an interaction between the dermis, the follicular proliferation and the epidermal proliferation of psoriasis is assumed.
