The treatment of vitiligo remains unsatisfactory. To assess in patients with vitiligo the effect of a laser dermabrasion in addition to the association of topical steroids and ultraviolet (UV) B in difficult-to-treat areas. This was a single-centre prospective randomized trial including patients with nonsegmental vitiligo who had at least two symmetrical lesions located on bony prominences and/or extremities. An erbium laser-assisted dermabrasion was first performed on one side (randomly assigned). After 48 h, hydrocortisone 17-butyrate cream applied daily for three periods of 3weeks followed by a 1-week steroid-free interval and narrowband UVB treatment was performed on both sides twice weekly for 12weeks. The evaluation was performed on standardized pictures by two physicians blinded to the type of treatment received. The criterion of success was a repigmentation of at least 50%, 1month after the end of the treatment. Eighteen patients were included (24 paired lesions treated). Two patients dropped out for personal reasons. Almost 50% of lesions achieved at least 50% repigmentation in the dermabrasion side while only 4·2% did so with topical steroids and UVB alone (P<10(-4) ). Side-effects were delayed healing, pain and two hypertrophic scars. The tolerance and patient satisfaction were 4·2 and 4/10 for the laser-treated side and 8·4 and 3/10 in the UVB+ steroids alone group, respectively. Laser dermabrasion significantly improves the repigmentation rate in vitiligo lesions. Despite a high rate of repigmentation in such difficult-to-treat areas the high rate of side-effects and the poor tolerance strongly limit its use in current practice. © 2011 The Authors.
