Pincer nail is a deformity characterized by excessive transverse curvature of nail, progressively increasing along its longitudinal axis. The curvature is greatest at the distal end, leading to an ingrown nail, producing pain, discomfort, and significant cosmetic alteration. It is a severe variant of ingrown nail, often attributed to causes such as anatomical variation of nail plate axis, tight footwear, gait abnormalities, and so on. Correspondingly, its management involves the removal of the lateral ingrowing nail plate or the lateral hypertrophic nail folds. We report a young male who presented with symptomatic pincer nail deformity. However, on exploration there was a midline onychomatricoma, leading to the thickening of the central part of the nail plate, causing incurving of the lateral nail plate and discomfort. The report serves to highlight the need for a comprehensive evaluation of pincer nails, to assess for matrix disease as well, because the surgical approach will differ accordingly.
钳形甲是一种以指甲横向过度弯曲为特征的畸形，沿其纵轴逐渐增加。弯曲在远端最大，导致嵌甲，产生疼痛、不适和明显的外观改变。它是嵌甲的一种严重变体，通常归因于甲板轴的解剖变异、紧鞋、步态异常等原因。相应地，其治疗包括切除外侧生长的甲板或外侧肥厚的甲襞。我们报告了一名患有症状性钳形甲畸形的年轻男性。然而，在探查时发现了中线甲母质瘤，导致甲板中央部分增厚，引起外侧甲板内弯和不适。该报告旨在强调对钳形甲进行全面评估的必要性，同时也要评估甲母质疾病，因为手术方法会因此而有所不同。
