Monilethrix is a rare hereditary disorder affecting hair resulting in hair fragility and alopecia. We report three patients of monilethrix who presented with complaints of sparse and brittle hair from early childhood. All three patients had multiple discrete hyperkeratotic papules over the scalp. Dermoscopy revealed beaded appearance of hair with the presence of elliptical nodes and intermittent constrictions on the hair shafts as well as broken hairs, which were confirmed with routine microscopic examination of hair. Dermoscopy helps in easier and faster diagnosis of monilethrix.
念珠状发是一种罕见的遗传性毛发疾病,会导致头发脆弱和脱发。我们报告了三名念珠状发患者,他们自幼就出现头发稀疏和脆弱的症状。所有三名患者头皮上都有多个离散的角化过度丘疹。皮肤镜检查显示头发呈串珠状外观,发干上有椭圆形结节和间歇性缩窄,还有断发,这些通过头发的常规显微镜检查得到了证实。皮肤镜有助于更轻松、快速地诊断念珠状发。
