Renal Cell Carcinoma (RCC) is known for its recurrence in 50% of the patients. The highest risk for its recurrence is in the first three to five years after the diagnosis has been made. A recurrence after ten years of diagnosis is known to occur in 11% of the patients. The natural history of RCC is unpredictable. An optimal surveillance protocol has been difficult to arrive at in view of its varied sites of recurrence and its varied time of recurrence. The sites of solitary recurrence can be anywhere in the body, but they have been found to be most commonly in the lung parenchyma (37%), bone (22%), liver (19%) and the brain (eight percent). It has been seen that early local treatment of the metastasis increases the survival. Bone metastasis is common but a disease free interval of more than 20 years has rarely been reported. We are describing here, a case of solitary bone metastasis which occurred very late, 32 years after the nephrectomy.
