To illustrate the diagnostic problems of rheumatic disease in patients over 60 years of age, 4 cases are presented: 1) osteoarthritis, 2) late-onset rheumatoid arthritis, 3) polymyalgia rheumatica, and 4) pseudogout with crystalline synovitis. In each case the correct diagnosis should have been suspected from the history and physical examination alone, with the laboratory and x-ray findings providing supportive evidence.
为说明60岁以上患者风湿性疾病的诊断问题，现介绍4个病例：1）骨关节炎，2）迟发性类风湿关节炎，3）风湿性多肌痛，4）伴有结晶性滑膜炎的假痛风。在每个病例中，仅根据病史和体格检查就应怀疑正确的诊断，实验室检查和X线检查结果提供支持性证据。
