摘要
目的描述黄褐斑的皮肤镜表现。方法使用皮肤镜观察临床表现典型的20例黄褐斑患者的黄褐斑区域及其周围正常皮肤的特征。结果病变区域在镜下表现为淡黄褐色均匀一致的斑片,其中19例为深褐色斑片/点、14例有毛细血管改变、6例的毳毛增粗变黑。正常皮肤的镜下表现为:未见淡黄褐色均匀一致斑片、10例为深褐色斑片/点、12例有毛细血管改变、2例的毳毛增粗变黑。病变部位与正常皮肤在背景颜色和深褐色斑点/片方面的差异有统计学意义(P均<0.001),在毛细血管分布和毳毛特征方面的差异无统计学意义(P均>0.05)。结论淡黄褐色均匀一致的斑片及深褐色斑片/点是黄褐斑的两大皮肤镜特征。
Objective To discribe the characteristic dermoscopic features of melasma. Methods Totally 20 patients with typical clinical presentations of melasma were included in this study. The melasma lesion and its surrounding normal skin were evaluated using dermatoscope. Results Melasma lesions manifested light yellow brown uniform patches in all patients,among whom dark brown patches were found in 19 patients,capillary network in 14 patients,and coarse hair in 6 patients. In contrast, no light yellow brown uniform patch was found in the normal skin in all patients（ P 〈0. 001）,among whom dark brown patches were found in 10patients（ P〈 0. 001）,capillary network in 12 patients（ P 〉0. 05）, and coarse hair in 2 patients（ P 〉0. 05）. Conclusion Light yellow brown uniform patches and dark brown patches are two major dermoscopic features of melasma.
