title: Anterior knee pain: an unusual presentation of renal cell carcinoma.
abstract: Metastasis of any kind to the patella is rare. Metastasis to the patella causing symptoms representing the first presentation of underlying malignancy is rarer still. We report the case of a previously fit and well 74-year-old male presenting with left anterior knee pain. The initial diagnosis was osteoarthritis but after continued symptoms a diagnosis of solitary patella metastasis from a primary renal cell carcinoma was confirmed.
