title: Vitiligo as a reaction to topical treatment with diphencyprone.
abstract: During the topical treatment of 45 patients, who had extensive forms of alopecia areata, with the allergen diphencyprone, 3 of them (6.7%) developed vitiligo. Two were females and 1 male aged 53, 19 and 28 years respectively. None of these patients had a personal or family history of vitiligo. Vitiligo appeared 3-5 months after the onset of treatment and was localized only to the areas of topical application in the younger woman and the man. In the older woman, vitiligo extended to several areas apart from those where the medicament was applied. After the end of diphencyprone treatment, vitiligo had a spontaneous significant improvement only in the man. Mitochondrial autoantibodies were found in the older woman only. To our knowledge, vitiligo due to diphencyprone has not been previously reported.
