Abstract

Background: Segmental vitiligo (SV), which frequently accompanies poliosis, indicating a poor prognosis that is likely resistant to treatments. Objectives: In this study, we performed a retrospective analysis to evaluate the treatment response to 308nm excimer laser in SV patients. Methods: A retrospective chart and photographic review was performed on 80 SV patients who had been treated with 308nm excimer laser for >3 months. Results: Eighty patients with SV (mean age: 24.0 years ± 15.3, males: 50%) were included in this study. The mean grade of repigmentation was 2.3 after 20.6 months of mean treatment duration; 23.8% of 80 patients showed grade 4, 20% showed grade 3, and 56.2% showed grade 1-2 repigmentation. However, none of them achieved complete repigmentation with excimer laser. The degree of repigmentation was positively correlated with treatment duration (r=0.315, P=0.004) and cumulative ultraviolet (UV) dosage (r=0.366, P=0.001), whereas it was negatively correlated with disease duration (r=-0.265, P=0.017). Conclusion: This study suggests that SV has a better repigmentation response when excimer laser is used at earlier stages of the disease and long-term use and high cumulative UV energy of the excimer laser elicit better responses. Additional treatments like surgical procedures in addition to excimer laser should be considered for complete repigmentation.
