【摘要】 目的 探讨鲜红斑痣患者皮损的皮肤镜特征，为临床诊治鲜红斑痣提供指导。方法 回顾性分析2020年1月—2024年2月本院皮肤科确诊的514例鲜红斑痣患者临床资料和诊断时皮肤镜下特征，并分析皮肤镜下血管类型与性别、年龄、病变部位、临床类型及治疗史等的关系。结果 鲜红斑痣皮肤镜下可分为点球状血管、网状血管、线状血管、不规则分支状血管、红色背景、混合型血管等不同种类。最常见的类型为混合型血管模式(49.73%),且以点球状合并线状血管模式为主(31.50%)。患者不同性别、治疗史的鲜红斑痣皮肤镜下各种特征差异无统计学意义(P>0.05)。患者不同年龄组、临床类型及病变部位的鲜红斑痣皮肤镜下特征差异有统计学意义(P<0.05)。结论 鲜红斑痣具有多种皮肤镜下特征，鲜红斑痣皮肤镜下血管模式与患者年龄、临床类型、病变部位有关。更多还原

【Abstract】 Objective To explore the dermoscopic features of skin lesions in patients with port wine stain(PWS), and provide guidance for clinical diagnosis and treatment of PWS.Methods The clinical data of 514 patients with PWS diagnosed in our dermatology department and their dermoscopic features of the PWS leisions were retrospectively analyzed from January 2020 to February, 2024. The correlation between dermoscopic features and the patients′ gender, age, location of lesions, clinical types, and treatment history of the PWS lesions were also analyzed.Results The dermoscopic patterns of PWS included: dotted and globular vascular pattern, reticular vascular pattern, linear vascular pattern, irregular branching vascular pattern, red background, and mixed vascular pattern.Mixed vascular pattern was the most common pattern of PWS(49.73%), among which the dotted and globular combined with the linear vascular pattern was predominant(31.50%). There was no significant difference in the dermoscopic features of PWS with different genders and treatment history of the patients(P>0.05). There was significant difference in the dermoscopic features with age of the patients, clinical types, and sites of lesions(P<0.05).Conclusion PWS has various dermoscopic patterns, which is associated with patients′ age, clinical types and location of PWS lesions.更多还原
