Wood's lamp for vitiligo disease stability and early recognition of initiative pigmentation after epidermal grafting

The prerequisite for a successful vitiligo epidermal grafting surgery is the stable status of the disease. We used Wood's lamp to assess vitiligo activity to determine the disease stability, surgical grafting timing and the early recognition of re‐pigmentation after grafting. Amelanotic lesions with sharply demarcated borders are typically stable and are good candidates for grafting. The re‐pigmentation was first recognised under Wood's lamp as hypochromic islands, which progressed to normally pigmented islands. For patients more prone to relapse, follow up with Wood's lamp also provides more accurate surveillance.
