The nail bed is an important part of the nail unit. It supports the nail plate, but does not regenerate itself. The labial mucosa and the nail bed both lack a granular layer. Because the keratinization of the nail bed can cause poor nail adhesion, harvesting graft from nonkeratinized sites is preferred. Furthermore, harvesting graft from labial mucosa is convenient in surgical approach. Therefore, the labial mucosa is more eligible for covering the nail bed defect than other graft methods. In this report, a 46-year-old female patient suffered from a subungal glomus tumor of the right fourth fingernail bed for 10 years. After the nail plate was removed, complete excision of the tumor was performed, and a labial mucosa graft was used to cover the defect. Eight months after the operation, the tumor had not reoccurred and no nail deformity was observed. This outcome demonstrates that our procedure is a good surgical option for treatment of nail bed defects.
甲床是甲单元的重要组成部分。它支撑甲板，但自身不会再生。唇黏膜和甲床均缺乏颗粒层。由于甲床的角化会导致甲板附着力差，因此更倾向于从非角化部位取皮瓣。此外，从唇黏膜取皮瓣在手术途径上更方便。因此，与其他植皮方法相比，唇黏膜更适合覆盖甲床缺损。在本报告中，一名 46 岁女性患者右第四手指甲床下有一个甲下血管球瘤，病史 10 年。在拔除甲板后，完全切除肿瘤，并使用唇黏膜皮瓣覆盖缺损。术后 8 个月，肿瘤未复发，也未观察到指甲畸形。该结果表明，我们的手术程序是治疗甲床缺损的一种较好的手术选择。
