Abstract

The nail unit is constructed by distinctly regulated components. The nail isthmus is a lately proposed region as a transitional zone between the most distal part of the nail bed and the hyponychium. It is difficult to recognize the nail isthmus in the normal nail, but it is easy to identify the region in nail disorders such as pterygium inversum unguis and ectopic nail. We describe structure and putative function of the nail isthmus via histopathologic features of pterygium inversum unguis and ectopic nail.

摘要

甲单元由明显受调控的成分构成。甲峡是最近提出的一个区域，作为甲床最远端部分与甲下皮之间的过渡带。在正常指甲中很难识别甲峡，但在如逆剥性甲翼状胬肉和异位甲之类的指甲疾病中很容易识别该区域。我们通过逆剥性甲翼状胬肉和异位甲的组织病理学特征来描述甲峡的结构和假定功能。
