title: Patellar metastases. A case report and review of the literature.
abstract: A case of metastasis to the patella from adenocarcinoma of the lung is reported. The clinical presentation was similar to septic arthritis of the knee. Histopathologic examination established the metastatic nature of the lesion; this is the first case in which a patellar lesion was the only evidence of distant metastasis. Metastatic tumors of the patella are rare. Three cases of metastasis to the patella have been described from squamous cell carcinoma of the lung in the English literature. We report the first case of patellar metastasis from adenocarcinoma of the lung.
