Approximately 5% of children with juvenile idiopathic arthritis (JIA) are diagnosed with the psoriatic form of the disease. In recent years, there has been substantial scholarship demonstrating both heterogeneity within the disease as well as similarities with other forms of JIA, culminating in a recent proposal for the categorization of JIA that excluded the psoriatic form altogether. The purpose of the review is to summarize the clinical, epidemiologic, and genetic features of psoriatic JIA (PsJIA), comparing it with other categories of JIA including spondyloarthritis. We conclude that there are sufficient unique clinical and genetic features within PsJIA as well as similarities with its adult counterpart that warrant including it within the JIA paradigm.

儿童银屑病关节炎：关于该争议的评论。

约5％的儿童特发性关节炎（JIA）儿童被诊断出患有银屑病。近年来，已经有大量学者证明该疾病内部的异质性以及与其他形式的JIA的相似性，最终导致了最近对JIA进行分类的提议，该提议将银屑病形式完全排除在外。综述的目的是总结银屑病JIA（PsJIA）的临床，流行病学和遗传学特征，并将其与其他类型的JIA（包括脊椎关节炎）进行比较。我们得出的结论是，PsJIA内具有足够的独特临床和遗传特征，以及与成年对等体的相似性，因此也应将其纳入JIA范式。
