Straight-hair nevus of the scalp is a distinct clinical entity. A case is reported and 2 other cases from the literature are reviewed. In our patient, specific morphology of the hair shown by scanning electron microscopy suggested a disorder in keratogenesis from loss of cuticular cells. Straight-hair nevus is probably a form of localized trichodysplasia.
头皮直毛痣是一种独特的临床实体。本文报告1例病例，并复习文献中的其他2例。在我们的患者中，扫描电子显微镜显示的毛发特殊形态提示角质形成细胞丢失导致的角化异常。头皮直毛痣可能是局限性毛发发育异常的一种形式。
