Abstract:
Photochemotherapy using psoralen and ultraviolet (UV)A irradiation (PUVA) is a useful treatment method for vitiligo. However, long-term PUVA therapy may cause several adverse effects including skin cancer, especially squamous cell carcinoma (SCC). We describe a case of SCC in vitiligo lesion after long-term PUVA therapy.
