Psoriatic arthritis (PsA) is a chronic inflammatory joint disease with heterogeneous clinical presentation and unpredictable course but often with a tendency to irreversible joint damage. Joint damage can occur early in the disease also in the absence of significant clinical signs of arthritis. These observations and the current availability of effective treatments in controlling skin and joint disease underline the importance of early diagnosis of PsA. The use of specific questionnaires for screening patients at risk of psoriatic arthritis, knowledge of new classification criteria for PsA and especially the proper use of new imaging techniques are all important steps in achieving the goal of early diagnosis of PsA. The dermatologist may play a key role in this regard supported, when necessary, by the collaboration of the rheumatologist and radiologist.
银屑病关节炎（PsA）是一种慢性炎症性关节疾病，具有不同的临床表现和不可预测的病程，但往往有不可逆关节损伤的趋势。即使没有明显的关节炎临床体征，关节损伤也可能在疾病早期发生。这些观察结果以及目前控制皮肤和关节疾病的有效治疗方法，强调了早期诊断 PsA 的重要性。使用特定的问卷筛查有患银屑病关节炎风险的患者、了解新的银屑病关节炎分类标准，特别是正确使用新的影像学技术，都是实现早期诊断 PsA 目标的重要步骤。皮肤科医生在这方面可以发挥关键作用，必要时可以得到风湿病学家和放射科医生的协作。
