Koebner phenomenon in vitiligo after suction blister epidermal grafting

摘要

A 14-year-old girl who had nonsegmental vitiligo on her face, trunk and extremities for more than 1 year presented for consultation on new areas of abdominal depigmentation. Two months earlier, she had undergone suction blister epidermal grafting. The donor sites were chosen from unaffected areas on her abdomen, and the recipient site was a depigmented patch on her face. Soon after the procedure, new depigmented macules and patches with a diameter of approximately 1 cm developed at previously unaffected donor sites (Figure 1). We diagnosed Koebner phenomenon secondary to suction blister epidermal grafting, and we prescribed oral prednisone 30 mg/d and topical pimecrolimus and halometasone. Two months later, the lesions had become less visible.
