Abstract:
The majority of patients with psoriasis benefit from ultraviolet radiation exposure, but psoriasis can deteriorate on exposure to sunlight in some people. We report a patient with longstanding palmoplantar psoriasis that showed an unusual evolution into photoaggravated psoriasis, with change of distribution from the palmar to the dorsal aspect of the hands, and confirmation by photoprovocation with solar-simulated radiation. The onset of photosensitivity should be suspected in patients with hand and foot psoriasis showing a similar change in distribution.
