摘　　要：目的:观察寻常型银屑病常见皮疹的皮肤镜表现特征,为皮肤镜鉴别诊断银屑病提供依据。方法:收集2016年1月至2018年2月我院皮肤科经临床诊断且11例经组织病理确诊为寻常型银屑病的86例患者。常见皮疹包括丘疹、红斑、斑块、头皮皮疹、掌跖皮疹、甲银屑病及治疗后皮疹,使用皮肤镜观察皮疹的背景颜色、鳞屑颜色、鳞屑分布、血管形态、血管分布。结果:典型的皮肤镜表现为亮红色背景,白色鳞屑弥漫性分布,点状血管、小球状血管规则一致性排列;而不同皮疹的皮肤镜表现有差异。结论:银屑病具有典型的皮肤镜影像表现,而不同皮疹有相对特异性表现,可用于临床辅助诊断。Objective:To observe the dermoscopic features of psoriasis vulgaris in order to provide evidence basis for differential diagnosis of psoriasis.Methods:From January 2016 to February 2018,86 cases of psoriasis,11 of which confirmed by histopathology,were enrolled in this study.Common lesions included papule,erythema,plaque,scalp rash,palmoplantar rash,nail psoriasis and post-treatment lesions.The background color,scale color,scale distribution,vascular morphology,vascular arrangement and vascular orientation were observed using a dermoscope.Results:Typical dermoscopic features of psoriasis included bright red background,silver scales,scattered distribution of dotted vessels and small glomerular vessels arranged in a uniform pattern.These features varied with the types of lesions.Conclusions:Psoriasis displays typical dermoscopic features.Specific dermoscopic features of each type of lesion can facilitate clinical diagnosis of psoriasis.
