Pterygium inversum unguis (PIU) is an uncommon nail abnormality in which the distal nail bed adheres to the ventral surface of the nail plate with obliteration of the distal nail groove. This rare condition, whether congenital, acquired, or idiopathic, has been reported in a few patients. Because of the rarity of this condition, the exact origin remains speculative. In addition, there have been no histopathologic features described in PIU. We describe an unusual case of acquired PIU of the right fingernails alone associated with a cerebral vascular accident resulting in right-sided paralysis and sensory deficit. We also present the first histologic features of PIU.
逆剥性甲翼状胬肉（PIU）是一种罕见的指甲异常，其中远端甲床粘附于甲板腹面，远端甲沟消失。这种罕见情况，无论是先天性、后天性还是特发性的，都在少数患者中有所报道。由于这种情况罕见，其确切起源仍属推测。此外，尚未有关于PIU组织病理学特征的描述。我们描述了一例仅累及右手指甲的后天性PIU的不寻常病例，该病例与脑血管意外相关，导致右侧瘫痪和感觉障碍。我们还展示了PIU的首个组织学特征。
