Twenty-nine patients with vitiligo and psoriasis observed over a 5-year period were reviewed. The incidence of concurrence of both diseases was not increased, and the onset and course of the psoriasis and vitiligo were separate. Psoriatic lesions occurred on vitiliginous areas and normal skin with equal frequency. These patients had a larger number of associated diseases than normally seen in psoriatics.
