Patients who develop metastatic arthritis secondary to solid tumors are rare. It is even more uncommon to be a presenting symptom. We present a case where a known case of osteoarthritic patient presented with complaints of knee swelling secondary to primary colonic carcinoma with lung metastasis. It was initially diagnosed on histopathology examination as metastatic adenocarcinoma from excised synovial mass and further investigated for primary carcinoma. Later, computed tomography was done and found out the primary colonic carcinoma arising from transverse colon along with lung metastasis.
继发于实体瘤的转移性关节炎患者较为罕见。作为首发症状则更为少见。我们报告了 1 例已知的骨关节炎患者，因原发性结肠腺癌伴肺转移而出现膝关节肿胀。最初通过切除的滑膜肿块的组织病理学检查诊断为转移性腺癌，并进一步探查原发性癌。随后进行了计算机断层扫描，发现原发性结肠癌起源于横结肠，并伴有肺转移。
