Photosensitive psoriasis in a vitiligo patient.

We report a case of a 15-year-old Caucasian female, previously affected by non-segmental vitiligo and psoriasis vulgaris, who developed a psoriatic eruption on sun-exposed skin during the summer. Oral therapy with cyclosporine A achieved a rapid improvement of the clinical picture. The main features of photosensitive psoriasis and the association between psoriasis and vitiligo are discussed herein.
