Abstract

Bone metastasis in lung cancer patients is common; however, metastasis to the patella is very uncommon. We report a case of lung squamous cell carcinoma with metastasis to the patella detected by synovial fluid analysis. The patient was a 79-year-old man. He was diagnosed as having lung squamous cell carcinoma (T2aN2M0, stage IIIA). He noted pain on his left knee, and various examinations were performed with the suspicion of infectious arthritis. Puncture fluid analysis included a quick Giemsa staining, and squamous cell carcinoma cells were detected. Patellar metastasis of lung cancer was diagnosed following diagnostic imaging. When lung cancer patients complain of pain on a knee, it is important to consider the metastasis of malignant cells in a general survey.
