[Utilisation of photochemotherapy by UVA and locally applied psoralens (author's transl)]

In the Skin Clinic of Neurnberg about 1,500 patients have been treated since 1972 with blacklight and 8-methoxypsoralen, approximately 120-150 every day. This new therapy has proved very good in psoriasis, acne, bacterial disseminated eczema, parapsoriasis and mycosis fungoides. The technique and the rate of relapses, the side effects and their endogenous as well as exogenous causes will be discussed.
