A 3-year-old boy presented two patches of light, bright, smooth, uncombable hair that were morphologically different from the rest of the hairs. Examination under scanning electron microscopy showed the morphologic characteristics of pili canaliculi and trianguli. Clinical and ultrastructural features seemed to correspond with a previously undescribed localized form of pili canaliculi et trianguli. Differential diagnosis is discussed.
一名3岁男孩出现两片浅色、明亮、光滑、无法梳理的毛发,其形态与其他毛发不同。扫描电子显微镜检查显示了毛小皮和三角形的形态特征。临床和超微结构特征似乎与之前未描述过的局限性毛小皮和三角形毛发形态相符。文中讨论了鉴别诊断。
