Rare sites of delayed metastasis in renal cell carcinoma.

Renal cell carcinoma (RCC) is a lethal malignancy with a propensity for metastatic spread to any part of the body. The common sites of metastases from RCC include lungs, adrenals, intestines and brain and most intra-abdominal organs which may present as synchronous or metachronous to the primary tumour. A long follow-up is advised to deal with the risk of delayed metastases even when the primary has been well controlled. There have been few case reports in regard to rare sites of RCC metastasis. In this series of three cases, we present three rarest sites of metastatic RCC reported after 5 years of the primary malignancy.
