Malignant tumors frequently metastasize to bone centrally in the skeleton. Metastatic disease distal to the knee is unusual. Metastasis to the foot (acrometastasis) is rare (0.01%) and is usually a late manifestation of disseminated disease. The purpose of this article is to present a rare case of metastatic renal cell carcinoma with foot metastasis as the primary manifestation along with another rare localization of metastatic disease distal to the knee, in the contralateral tibial diaphysis. To highlight the delay in diagnosis of such a rare condition to consider it in the diagnosis of a painful foot, we also present a review of the literature.
