Squamous Cell Carcinoma in a Patient with Vitiligo of Photo-covered Skin

Ultraviolet radiation is an important risk factor for the development of skin cancers. Melanin is known to protect the skin against harmful effects of ultraviolet radiation. Hence, vitiligo patients are at higher risk of developing such malignancies. But few reports of occurrence of skin cancers in vitiligo lesions suggest that their occurrence in vitiligo is rare. There are reports of development of Squamous cell carcinoma (SCC) in vitiligo lesions, following long-term Psoralen and Ultraviolet-A (PUVA) therapy. But there are no reports of occurrence of SCC in a vitiligo patch located in photo-covered area. We describe a patient with SCC in a vitiligo patch present in photo-covered skin.
