Dermatoscopy in Vitiligo: Diagnosis of the Stages

2021 Indian Journal of Forensic Medicine & Toxicology  
The aim of the Study is to identify the main dermatoscopic patterns of vitiligo and to establish their relationship with the activity of the process. Materials and Methods: The study involved 63 patients with an established diagnosis of vitiligo. There were 34 patients with a progressive course, 11 with a stable and 18 in the repigmentation stage. All patients underwent dermatoscopy using a Delta 20T dermatoscope. Statistical processing of research materials was carried out using the SPSS

So, progressive vitiligo is characterized by perifollicular pigmentation (91.2%), an altered pigment network (97.1%), a blurred spot border (94.1%), as well as specific structures -star-shaped formations and "comet tail". A stable vitiligo process is characterized by perifollicular depigmentation (81.8%), a sharp spot border (72.7%). For the stage of repigmentation, marginal hyperpigmentation (100%), perifollicular depigmentation (72.2%), blurred spot border (77.8%), "pigmentation islands" (77.8%). Conclusion. For the first time, diagnostic dermatoscopic patterns of vitiligo have been developed, and their value has been shown. Dermatoscopy is a promising auxiliary non-invasive tool for diagnosing vitiligo and determining the stage of the disease.
