We report here our experience on the use of dermoscopy for the detection of subungual red comets, which are sometimes present in the nails of patients affected by tuberous sclerosis complex. Dermoscopy allowed us to visualize, with better resolution than the naked eye, very tortuous capillaries surrounded by a whitish halo and close parallel binary tortuous capillaries. In some cases, subungual red comets are associated with the presence of periungual or subungual fibromas, but their exact pathogenesis remains unknown.
我们在此报告我们使用皮肤镜检测甲下红色彗尾征的经验，甲下红色彗尾征有时出现在结节性硬化症患者的指甲中。皮肤镜使我们能够以比肉眼更高的分辨率观察到，非常迂曲的毛细血管周围有白色晕圈以及紧密平行的双迂曲毛细血管。在某些情况下，甲下红色彗尾征与甲周或甲下纤维瘤的存在有关，但其确切发病机制尚不清楚。
