Actinic keratoses arising only on sun-exposed vitiligo skin.

A 71-year-old woman with vitiligo developed multiple actinic keratoses only on the vitiligo skin of sun-exposed areas. She had worked outdoors as a farmer for a long period. Although actinic skin cancers arising on vitiligo skin have rarely been reported, the present case demonstrates that vitiligo skin is more susceptible to actinic damage than normal skin. Patients with vitiligo should be well informed about the importance of sun protection.
