摘　　要：目的探讨儿童传染性软疣(MC)的皮肤镜下图像特征。方法回顾性分析2022年5月至2023年5月郑州大学第三附属医院皮肤科门诊确诊的62例儿童MC 140处皮损的皮肤镜下图像特征。结果140处皮损中临床观察到22处(15.71%)脐凹和孔、13处(9.28%)血管;皮肤镜下观察到31处(22.14%)脐凹和孔、138处(98.57%)黄白色无结构区和127处(90.71%)血管。138处无结构按出现频率由高到低分别为圆形(86、62.32%)、多叶形(24、17.39%)、四叶草形(14、10.14%)、非特异形(10、7.24%)、三叶草形(4、2.89%)。单纯MC组、MC合并炎症或剥脱组以及MC合并湿疹组之间不同类型无结构区出现的频率差异无统计学意义(P>0.05);127处血管结构可分为:单一血管模式96处(75.59%),其形状按出现频率由高到低分别为放射线状(53处,55.21%)、皇冠状(31处,32.29%)、点状(12处,12.50%);混合血管模式(含有2种及以上血管模式)31处(24.41%)。与单纯MC组比较,点状血管在MC合并炎症或剥脱组及MC合并湿疹组中占比均升高(P<0.05)。结论儿童MC皮肤镜下具有黄白色无结构区、血管结构和孔特征性表现,皮肤镜可作为有效的无创性诊断方法。Objective To explore the dermoscopic image features of molluscum contagiosum(MC)in children.Methods Retrospective analysis of dermoscopic image features of 140 lesions from 62 cases of MC diagnosed at the Dermatology Outpatient Clinic of the Third Affiliated Hospital of Zhengzhou University from May 2022 to May 2023.Results Of the 140 lesions,22(15.71%)had umbilication and holes,13(9.28%)had vessels on clinical examination.Under dermoscopy,31(22.14%)had umbilication and holes,138(98.57%)had yellow-white structureless areas and 127(90.71%)had vessels.The 138 structureless areas were classified by frequency of occurrence from high to low as round(86,62.32%),multilobular(24,17.39%),cloverleaf(14,10.14%),nonspecific(10,7.24%),and trefoil(4,2.89%).There was no statistically significant differences in the frequencies of different types of structureless areas between the simple MC group,the MC group with inflammation or peeling,and the MC group with eczema(P>0.05).The 127 vascular structures can be divided into:single vascular mode 96 cases(75.59%)[in descending order of frequency of shapes,they are radial(53 cases,55.21%),crown-shaped(31 cases,32.29%),and dot-shaped(12 cases,12.50%)],and 31 cases(24.41%)of mixed vascular mode(including two or more vascular modes).The proportion of punctate blood vessels is increased in the MC group with inflammation or exfoliation and in the MC group with eczema compared to the simple MC group(P<0.05).Conclusion MC in children exhibits characteristic features under dermoscopy,including yellow-white structureless areas,vascular structures,and pores.Dermoscopy can serve as an effective non-invasive diagnostic method.
