Abnormalities of the nail are not a well recognized feature of palmoplantar pustulosis (PPP). However, in a group of 50 patients with PPP, we found nail dystrophy in 15 (30%). The most frequent pattern was subungual pustulation, present in 10 patients, and progressing to nail destruction in two. Onycholysis and pitting of the nail were present in a few patients. In contrast to psoriasis vulgaris, the rate of linear nail growth in PPP was no greater than in matched normal controls. This is another clinical feature of PPP that separates it from psoriasis vulgaris.
指甲异常并非掌跖脓疱病（PPP）为人熟知的特征。然而，在一组50例PPP患者中，我们发现15例（30%）存在甲营养不良。最常见的表现是甲下脓疱形成，10例患者出现此症状，其中2例进展为指甲毁损。少数患者存在甲剥离和指甲凹点。与寻常型银屑病不同，PPP患者指甲的线性生长速度并不高于相匹配的正常对照者。这是PPP区别于寻常型银屑病的另一临床特征。
