Co-occurrence of Vitiligo and Psoriasis in an 11-Year-Old Girl: A Case Report

Abstract

Introduction:Vitiligo and psoriasis are common skin diseases, while its co-occurrence in one patient is rare. Here, we reported a patient with co-occurrence of vitiligo and psoriasis.Case presentation:An 11-year-old girl developed depigmented patches on her right chin for 6 months. The noticed areas of depigmented skin steadily increased in size with no clinical symptoms. Wood's lamp examination and laser scanning confocal revealed the clinical diagnosis of co-occurrence of vitiligo and psoriasis.Discussion:Speculations related to co-pathogenesis of vitiligo and psoriasis are still elusive, some explanations of this phenomenon like of isomorphic reaction, shared genetic basis of autoimmunity and inflammation, shared cellular immune pathways including Th1, Th17 and related cellular molecules such as TNF-α, IFN-α, IL-17 have been reported.Conclusion:The analysis and summary of the underlying association in co-occurrence of psoriasis and vitiligo may amplify future therapeutic options for both disease.Clinicians should pay attention to the methods that could simultaneously improve these two conditions.
