Different therapeutic approaches for vitiligo include nonsurgical and surgical methods but effective therapy is still challenging. There are few studies that suggest the role of vitamin D analogs in the repigmentation process with encouraging results. To our knowledge, this is the first study to evaluate the effect of topical vitamin D (cholecalciferol) combined with microneedling in the treatment of depigmented patches of vitiligo.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aim of the Work<\/jats:title><jats:p>Evaluate the effect of microneedling alone versus microneedling with topical vitamin D in the treatment of vitiligo.<\/jats:p><\/jats:sec><jats:sec><jats:title>Patients and Methods<\/jats:title><jats:p>A prospective comparative clinical trial was carried out on 25 patients with stable vitiligo; every patient had at least two patches; the first patch was treated with microneedling alone.
