摘要： 我们用扫描电镜观察4例小棘伏毛雍症的毳毛,发现毳毛有两种形态:①毳毛粗细不等,毛小皮完整,②毳毛毛小皮消失或毳毛表面有许多角化上皮碎片伴有浅沟.推测本病发病机理可能是由于毛乳头营养障碍,致使毛髓质发育不良.毛皮质角化异常所致.

Abstract: Lanugoes from four patients with trichostasis spinolosa were studied. Morphologically two types of lanugoes were observed:(1)lanugoes varied in diameter Gut with intact cuticle, and(2) those with their cuticle disappeared or with many fragments of keratinocyte on their surface accompanied by the presence of shallow ditches. The disease is presumably due to malnutrition of the hair papillae resulting in medulla dysplasia and abnormal keratinization of the cortex.
