摘要
目的:观察雄激素性脱发(AGA)患者的皮肤镜征象。方法:收集30例雄激素性脱发患者,16例斑秃患者及24例健康对照组的皮肤镜征象及相关临床资料,并进行比较分析。结果:雄激素性脱发皮肤镜征象按照出现频率由高到低依次为:毛干直径差异>20%、蜂窝状色素沉着、毳毛增多、单一毛囊单位增多、白色鳞屑增多、毛细血管扩张、褐色毛周征、白点征、局部无毛症等,其中毛干直径差异>20%发生率最高。毛干直径差异>20%、蜂窝状色素沉着、单一毛囊单位增多、毳毛增多、白点征、褐色毛周征的发生率在雄激素性脱发患者明显高于健康人群;黄点征、黑点征、断发、感叹号发的发生率在雄激素性脱发患者则低于斑秃患者。结论:皮肤镜在早期诊断脱发疾病上具有重要的临床意义。其中毛干直径差异>20%是诊断AGA早期病程的重要依据。
Objective To observe and analyze the features of androgenetic alopecia(AGA)with dermoscopy and study its signi ficance for clinical diagnosis.Methods Clinical information and dermoscopic features of 30 patients with androgenetic alopecia,16 patients with alopecia areata and 24 normal volunteers served as controls were collected and analyzed.R e s u l t s The most common dermoscopic features of AGA was hair diameter diversity>20%、honeycomb pattern pigmentation、increased vellus hairs、increased single follicle units、white scales increasing、telangiectasia、brown peripilar sign、white dots and focal atrichia.The incidence rate of hair diameter diversity>20%was the highest.The incidence rate of hair diameter diversity>20%、honeycomb pattern pigmentation、increased single follicle units、increased vellus hairs、white dots、brown peripilar sign was higher in patients with AGA than that in controls.The incidence rate of yellow dots、black dots、hair tapering and exclamation mark hairs was lower in patients with AGA than those with alopecia areata.Conclusion Dermoscopy plays an important role in early diagnosis hair loss diseases.Hair diameter diversity more than 20%is the important criteria in the early diagnosis of AGA.
