To discribe the characteristic dermoscopic features of melasma.
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.
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 10 patients (P<0.001), capillary network in 12 patients (P>0.05), and coarse hair in 2 patients (P>0.05).
Light yellow brown uniform patches and dark brown patches are two major dermoscopic features of melasma.
描述黄褐斑的特征性皮肤镜表现。
本研究纳入20例具有典型黄褐斑临床表现的患者。使用皮肤镜评估黄褐斑皮损及其周围正常皮肤。
所有患者的黄褐斑皮损均表现为浅黄褐色均匀斑片，其中19例患者有深褐色斑片，14例患者有毛细血管网，6例患者有粗毛。相比之下，所有患者的正常皮肤均未发现浅黄褐色均匀斑片（P<0.001），其中10例患者有深褐色斑片（P<0.001），12例患者有毛细血管网（P>0.05），2例患者有粗毛（P>0.05）。
浅黄褐色均匀斑片和深褐色斑片是黄褐斑的两个主要皮肤镜特征。
