【摘要】：目的 :探讨急性休止期脱发(ATE)患者的临床及皮肤镜表现。方法 :回顾性分析15例ATE患者(患者组)的临床资料和皮肤镜表现,收集10例正常人毛发皮肤镜表现作为正常对照组。结果:15例ATE患者脱发起病急,为弥漫性脱发,全头拉发试验弱阳性,病程持续5~11周,平均7.3周。与正常对照组比较,患者组皮肤镜下表现为新生毳毛的数目增多及近皮面毛干的渐进性色素减退,色素减退毛干所占比例与病程长度呈负相关。脱落的毛干近毛根处亦有色素减退,毛根为杵状休止期和柱状排出期,排出期毛根部较为狭窄。病情恢复后,所有患者毛发恢复良好。结论:ATE临床特征明显,结合皮肤镜表现可初步诊断,皮肤镜下新生毳毛及色素减退毛干的比例能够提示病程长度。该病具有自限性,可在数月内完全恢复。
[Abstract]:Objective: to investigate the clinical and dermatoscopic manifestations of patients with acute atresia. Methods: the clinical data and dermoscope findings of 15 patients with ATE were retrospectively analyzed, and 10 normal subjects were collected as the normal control group. Results in 15 cases of ATE, the onset of hair loss was urgent, which was diffuse alopecia. The whole head pulling test was weakly positive. The course of disease lasted for 5 to 11 weeks with an average of 7.3 weeks. Compared with the normal control group, the number of new vellus hair and the progressive pigmentation of the proximal hair stem were increased under the skin microscope in the patient group, and the proportion of pigmented hair stem was negatively correlated with the course of disease. Pigmentation was also found in the abscission of the hair stem near the hair root. The hair root was in the pestle rest period and the columnar expulsion period, and the hair root was narrower in the excretion stage. The hair of all patients recovered well after recovery. Conclusion the clinical features of the head ate are obvious and the proportion of newborn vellus hair and hypochromatic hair can indicate the length of the disease course. The disease is self-limited and can be fully recovered within a few months.
