[Treatment of psoriasis (author's transl)].

From an examination of all possible methods for the treatment of psoriasis and the therapeutic results obtained with them, the author emphasizes the outstanding efficacy of a method for the treatment of psoriasis only recent described in the medical literature, which consists of a combination of methoxsalen by mouth and longwave ultraviolet light. In almost all cases treated with this "photochemotherapy" a rapid and complete regression of the extensive psoriasis lesions could, in fact, be observed without being able to detect toxic systemic side effects or secondary alterations of the skin. As a result of a recent trial of his own, the author points out that the results of photochemotherapy of psoriasis can equally well be obtained with "Trisoralen" by mouth and sunlight.
