Depigmented haloes sometimes appear around melanocytic tumors or non-melanocytic tumors, but coexistence of warts and depigmented haloes is extremely rare. We report here an unusual case of warts accompanied by depigmented haloes and subsequently-triggered generalized vitiligo. A 55-year-old Japanese man presented with a 3-year history of brown nodules on the back, upper eyelid and dorsum of the left hand. Depigmented haloes appeared around the noldules and then gradually spread over a wide area, resulting in the development of generalized vitiligo. He had no history of antecedent treatment for these lesions before consultation. Histopathologically, the lesion showed papillomatosis and hyperkeratosis with lymphocytic exocytosis into the epidermis, which compatible to warts. Based on these clinical and histopathologic findings, a diagnosis of warts with depigmented halo and subsequently-triggered generalized vitiligo was made. None of the warts had resolved spontaneously after the appearance of haloes, and the depigmented haloes and generalized vitiligo remain unchanged.
