Trichothiodystrophy is a rare autosomal recessive disorder resulting in a broad range of systemic abnormalities. Polarizing microscopy of the hair reveals the pathognomic "tiger tail" of alternating light and dark bands, but the need for a microscope prevents rapid bedside diagnosis. We describe a new technique for the bedside diagnosis of trichothiodystrophy using a handheld polarizing dermatoscope, precluding the need for microscopic examination.
毛发硫营养不良是一种罕见的常染色体隐性疾病，会导致一系列广泛的全身异常。毛发的偏光显微镜检查可发现具有诊断意义的明暗交替的“虎尾”现象，但由于需要显微镜，无法进行快速床边诊断。我们描述了一种使用手持式偏振皮肤镜进行毛发硫营养不良床边诊断的新技术，无需显微镜检查。
