Abstract：
Arthritis is an unusual manifestation of paraneoplastic syndrome, appearing in a variety of cancers, including pulmonary and colorectal. It can often pose a diagnostic challenge to physicians, since it may be difficult to distinguish from more commonly encountered rheumatic illnesses. Moreover, synchronous cancers are rare and unexpected in patients with symmetrical polyarthritis. Hypertrophic pulmonary osteoarthropathy is to be considered in patients with polyarthritis and lung neoplasia. The aim of this report is to highlight the case of a patient presenting with paraneoplastic polyarthritis, which led to identifying the presence of underlying synchronous lung and colorectal malignancies. Lymph node biopsy was performed raising suspicion of Caplan\'s syndrome but lung lobectomy confirmed adenocarcinoma. Rheumatologists should be reacquainted with rheumatic manifestations in malignant diseases.
摘要：
关节炎是副肿瘤综合征的不寻常表现,出现在各种癌症中，包括肺和结肠直肠。它通常会给医生带来诊断挑战，因为它可能很难与更常见的风湿性疾病区分开来。此外，在对称性多关节炎患者中，同步癌症是罕见且出乎意料的。在患有多关节炎和肺肿瘤的患者中，应考虑肥厚性肺骨关节炎。本报告的目的是强调一名患有副肿瘤性多关节炎的患者，这导致确定潜在的同步肺和结肠直肠恶性肿瘤的存在。进行淋巴结活检，怀疑卡普兰综合征，但肺叶切除术证实为腺癌。风湿病学家应该重新认识恶性疾病中的风湿性表现。
