Bone of the hands as unusual metastastatic site of renal cell carcinoma

Metastases to the bones of the hands and feet (acrometastases) represent an uncommon site of recurrence of renal cell carcinoma (RCC). Although challenging, the prompt recognition of solitary acrometastasis from RCC is of crucial importance, since surgical resection of the acrometastasis in the absence of active systemic disease has been reported as beneficial for a subgroup of patients with RCC. Here, we report the case of a patient with RCC metastatic to the left index finger treated with surgical resection of the acrometastasis who shortly thereafter developed progressive disease despite such an aggressive surgical approach.
