We describe a Brazilian girl with a congenital circumferential nail on her left ring finger associated with other bony and soft tissue abnormalities of the affected limb. The tubular nail plate resembling a punch biopsy has been described as a circumferential nail, an extremely rare congenital malformation that can be associated with other congenital anomalies. In our review of the literature, there have only been two previous reports of this unusual condition affecting the fingernails.
我们描述了一名巴西女孩，她左手环指有一个先天性环形指甲，并伴有患侧肢体的其他骨骼和软组织异常。这种类似打孔活检的管状指甲板被称为环形指甲，是一种极其罕见的先天性畸形，可与其他先天性异常相关联。在我们对文献的回顾中，此前仅有两篇关于这种影响指甲的罕见病症的报告。
