Clinical repigmentation patterns in paediatric vitiligo

Summary Background Repigmentation is an essential outcome measure in vitiligo. However, clinical studies describing vitiligo repigmentation patterns are lacking. Objectives To assess and clearly define the repigmentation patterns in a series of patients with vitiligo, correlating these with clinicoepidemiological characteristics. Methods Patients with vitiligo seen at least at twice (initial consultation and follow‐up visit) in the Department of Paediatric Dermatology, Hôpital Pellegrin des Enfants, Bordeaux University Hospital from 2006 to 2014 were included. Clinical photographs and case records were reviewed. Results There were 109 patients (64 female, 45 male) mostly with Fitzpatrick skin type III (n = 67, 61%). The majority had nonsegmental (n = 71, 65%) or segmental vitiligo (n = 29, 27%). In total 172 representative vitiligo lesions were analysed. Overall, a combined pattern of repigmentation was most commonly seen (n = 106, 62%). The combined pattern occurred more frequently in patients with segmental vs. nonsegmental vitiligo (P = 0·009), whereas the diffuse pattern was more frequent in the latter (P = 0·007). Diffuse repigmentation was the predominant pattern on the eyelids (P
