Scabies is an ectoparasitosis caused by Sarcoptes scabiei var. hominis, characterized clinically by pruritic lesions in typical locations; the crusted form is a rare manifestation. The diagnosis is usually established based on the clinical picture, but dermoscopy can be an important complementary method, as it allows the observation of a brownish triangular structure with a hang-glider appearance. A case of crusted scabies is reported; the magnification of the images obtained by digital dermoscopy allowed the demonstration of a structure usually observed only with videodermoscopy.
疥疮是由人疥螨引起的一种体表寄生虫病，临床上以典型部位出现瘙痒性皮损为特征；结痂型是一种罕见的表现形式。诊断通常基于临床表现，但皮肤镜检查可以作为一种重要的辅助方法，因为它能够观察到呈悬挂式滑翔机外观的褐色三角形结构。本文报告了1例结痂型疥疮病例；通过数字皮肤镜获得的图像放大后显示出一种通常仅在视频皮肤镜下才能观察到的结构。
