Renal Cell Carcinoma Metastases to the Pancreas and the Thyroid Gland: A Case Report and Review of the Literature.

Renal cell carcinoma (RCC) is known for having unpredictable clinical behavior. Metastases can occur in unusual locations with a long-time lag after the treatment of the primary cancer. Despite being a sign of poor prognosis, aggressive metastasectomy may prolong survival. Presented is a case of delayed sequential metastases of RCC to the pancreas and the thyroid gland that occurred eight years after the radical nephrectomy. Both were resected. A history of remote nephrectomy for RCC is important and may be suggestive of metastatic disease. Ultrasound-guided fine needle aspiration can be diagnostic and helps in decision-making. Aggressive surgical intervention when possible is recommended.
