Straight-hair nevus syndrome: a case report with scanning electron microscopic findings of hair morphology.
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.
