Psoriatic arthritis (PA) is a chronic systemic disease that is difficult to detect. The diagnosis is made on mainly clinical grounds based on the findings of psoriasis and inflammatory arthritis of the joints. Many reports have described the damaging effects of PA on the temporomandibular joints (TMJs), but no study has clearly reported the TMJ as the first articulation to be involved in PA. This article reports a case of PA that was diagnosed several years after TMD onset because no signs besides psoriasis were present. The missed early diagnosis resulted in severe TMJ damage. The TMJ can be the first joint involved in PA. For a correct, early diagnosis of PA, collaboration between dental clinicians and rheumatologists is very important.
银屑病关节炎（Psoriatic arthritis，PA）是一种难以检测的慢性全身性疾病。诊断主要基于临床依据，根据银屑病和关节炎性关节炎的表现来进行。许多报告描述了PA对颞下颌关节（temporomandibular joints，TMJs）的损害作用，但尚无研究明确报告TMJ是PA中首个受累关节。本文报告了一例PA病例，该病例在颞下颌关节紊乱病（temporomandibular disorder，TMD）发病数年之后才得以诊断，因为当时除了银屑病外没有其他症状。早期诊断的遗漏导致了严重的TMJ损害。TMJ可能是PA中首个受累关节。为了正确、早期诊断PA，牙科临床医生和风湿病学家之间的合作非常重要。
