Rheumatoid arthritis is mainly a chronic and disabling articular disease. If most patients do well (because of limited form or efficient treatment), in some cases they present with extra-articular rheumatoid arthritis. The clinical manifestations of extra-articular rheumatoid arthritis are wide, ranging from common and benign manifestations such as rheumatoid nodules to severe events such as Felty's syndrome or systemic vasculitis. The incidence of systemic rheumatoid arthritis seems cumulative over the course of the chronic disease, and the severity of individuals lesions when fully developed can be of major importance and even life threatening. A classification of the main features of extra-articular rheumatoid arthritis is given (even if not perfect), and the clinical manifestations are described.
类风湿性关节炎主要是一种慢性致残性关节疾病。如果大多数患者病情良好（由于病情形式有限或治疗有效），在某些情况下，他们会出现关节外类风湿性关节炎。关节外类风湿性关节炎的临床表现广泛，从类风湿结节等常见和良性表现到费尔蒂综合征或系统性血管炎等严重情况。系统性类风湿性关节炎的发病率似乎在慢性疾病过程中呈累积性，个体病变充分发展时的严重程度可能至关重要，甚至危及生命。本文给出了关节外类风湿性关节炎主要特征的分类（即使并不完美），并描述了其临床表现。
