This article discusses the use of reflectance confocal microscopy (RCM) as a diagnostic tool for vulvar lichen sclerosus (VLS) and vulvar vitiligo (VV) in juvenile Chinese girls. VLS and VV have similar clinical appearances, but RCM can reveal distinct features that aid in diagnosis. The study examined 28 patients, with 17 having VLS and 11 having VV. The results showed that VLS is characterized by structural disorder, fibrous material deposits, and larger cellular structures, while VV is characterized by weakened dermal papillary rings. The authors suggest that RCM can be used to support clinical diagnosis of VLS and VV. [Extracted from the article]
