[Selective ultraviolet phototherapy (SUP) for prophylaxis of polymorphous light eruption (author's transl)].

16 patients with polymorphous light eruption were prophylactically treated with selective ultraviolet phototherapy (SUP). Ten patients showed no or only minimal signs of their disease in a following holiday with high sun exposition; 4 patients had the same skin manifestations as in the years before. Indirect evaluation of the therapeutic success had to be performed in two patients, who did not have holidays in this year. Thus SUP may represent a new prophylactic treatment of polymorphous light eruption.
