[Therapy of psoriasis]

The possible methods of treating psoriasis and results obtained are reviewed and the superior effectiveness of an approach reported in recent literature, an association of methoxalene per os and broad ultraviolet rays, is pointed out. In almost all cases submitted to such "photochemotherapeutic" treatment, regression of diffused lesions was rapid and complete with no systemic toxic effects or secondary skin alterations. On the basis of recent personal experience, it is stated that similar results may be obtained by the photochemotherapy of psoriasis with appropriate doses of Trisoralen per os and sunlight.
