Investigations on light reactions in a patient with vitiligo are presented. The minimal erythema dose (MED) in the UVB area was approximately 1/3 of that in persons of skin type II. The application of furocoumarins (psoralens) increased light tolerance by 1 MED at 300-310 nm. Action spectrum studies
