Renal cell carcinoma with solitary metastases appearing during 18 years of follow-up

Abstract

Summary We present a case of renal cell carcinoma with solitary metastases to the thyroid, the post-nephrectomy scar and the lungs, appearing during an 18-year period following nephrectomy.

Renal cell carcinoma metastases to the pancreas and the thyroid gland 19 years after the primary tumour

“…Secondary (metastatic) cancers of the thyroid gland are a rarity. They comprise clinically barely 0.5% of all thyroid neoplasms [ 18 ]. Secondary thyroid cancer does not allow for an easy diagnosis.…”

“…Secondary thyroid cancer does not allow for an easy diagnosis. In 70% of cases the primary source of thyroid metastases is the RCC [ 8 , 18 ]. Most authors believe 1% to 5% of RCC metastases are localised in the thyroid gland [ 4 , 19 , 20 ].…”

“…Several authors have reported long-term survival after surgical metastasectomy in RCC [ 1 , 2 , 18 , 22 ]. Renal cell carcinoma metastases to the pancreas are usually singular and symptomatic.…”
