目的:探讨皮肤镜下斑秃临床特征表现。方法:分析2013年12月至2014年11月我科门诊确诊为斑秃的96例患者的临床资料、皮肤镜特征。结果:斑秃患者脱发区域皮肤镜征象包括黄点征、黑点征、断发、感叹号样发、短毳毛(新生短发<10 mm)。其中黄点征发生率最高,达69.8%,是诊断斑秃的敏感指标;感叹号样发、黑点征、断发在活动期发生率高,分别是40.6%、52.1%、48.9%,是斑秃重要的皮肤镜征象。结论:上述皮肤镜征象在斑秃的诊断、活动性评判及疗效评估上有较高的应用价值。

Objective： To analyze dermoscopic findings of alopecia areata（ AA） that can be used as clinical indicators of disease diagnosis. Methods： The dermoscopic findings in 96 newly diagnosed AA patients and dermoscopic examination of areas of hair loss on the scalp were collected. Results： Characteristic dermoscopic findings of AA included yellow dots,black dots,broken hairs,exclamation mark sample hair,and clustered short vellus hairs（ shorter than 10 mm）. The highest incidence appears in yellow dots which up to 69. 8%,and can be regarded as a sensitive indicator in the diagnosis of alopecia areate. Exclamation mark sample hair（ 40. 6%）,black dots（ 52. 1%）,broken hairs（ 48. 9%） all were highest in the active phase,which were important sigh of alopecia areata. Conclusion： Dermoscopic signs are highly useful in diagnosis,evaluation for activity and therapeutic effect of AA.
