扁平苔藓皮肤镜构型特征

Dermatoscopic Patterns of Lichen Planus

目的观察扁平苔藓皮肤镜下构型特点。方法对2010年3月-2012年2月9例扁平苔藓共43处皮损的临床资料及皮肤镜下构型表现进行回顾性分析。结果肉眼下20.93%皮损可见Wickham纹,皮肤镜下37.21%皮损见清晰的Wickham纹,呈水晶白色或黄色,中央可见蓝白幕。Wickham纹可为圆形、叶脉型、网状和满天星等;色素改变除色素点、胡椒粉样色素外,还见色素线。血管改变为红点或Wickham纹周围放射状血管形成的红线。结论皮肤镜可作为扁平苔藓无创性诊断手段。

Objective To investigate dermatoscopic patterns of lichen planus（LP）. Methods Clinical data and der- matoscopic changes of nine LP patients with a total of 43 lesions were reviewed retrospectively. Results 20.93% lesions had Wickham＇ s striae under naked eyes. Dermatoscopically, 37.21% presented with crys- talline white streaks of annular, reticular, or leaf venation patterns. Blue white veils commonly presented at the center. Pigmentary dermatoscopic patterns varied from dots, globules, peppering pigments to pigmented streaks. Red dots or radial vascular lines decorated peripherals of the Wickham＇ s striae. Conclusion Der- matoscope is a effective, noninvasive diagnostic method to LP.
