Pterygium inversum unguis (PIU) is a rare nail abnormality in which the distal nail bed adheres to the ventral surface of the nail plate, with obliteration of the distal groove. Because of the rarity of this condition, its exact origin is unknown. This disorder can be either congenital or acquired, with or without a family history. The acquired forms may be idiopathic or secondary to systemic connective tissue diseases or other causes such as stroke, neurofibromatosis, leprosy, or the use of nail fortifiers. We present an unusual case of acquired idiopathic PIU of the 10 fingernails in a 22-year-old man.
逆剥性甲翼状胬肉（PIU）是一种罕见的指甲异常，其中远端甲床附着于甲板的腹面，远端甲沟消失。由于这种情况罕见，其确切病因尚不清楚。这种疾病可以是先天性的，也可以是后天获得性的，有无家族史均可。后天获得性形式可能是特发性的，或继发于系统性结缔组织疾病或其他原因，如中风、神经纤维瘤病、麻风病或使用指甲强化剂。我们报告一例22岁男性10个手指均出现后天获得性特发性PIU的不寻常病例。
