ABSTRACT
The thyroid metastasis are under estimated in clinical practice because they are in the vast majority of cases "silent". Over than 50% of clinically apparent metastatic lesions are due to kidney carcinomas. We report two cases of thyroid metastasis from clear-cell renal carcinoma occurred 3 years and 8 years after nephrectomies. The previous history of any type of carcinoma should suggest a possibility of metastasis for every thyroid nodules. Fine-needle aspiration cytology is recommended by some authors. Finally, clear-cell carcinoma metastases seem to have a propensity to occur in abnormal thyroid tissue and further study could be interesting.

A 67-year-old man with anti-HCV positive serum, was admitted for hematemesis by variceal bleeding. Portal hypertension, which initially was thought to be caused by a post-hepatitis C cirrhosis, was due to a fistula between a right hepatic artery and a right branch of the portal vein. The fistula located under the right liver and the adjacent atrophic hepatic segments, were resected by a bi-segmentectomy VI-VII. The postoperative course was simple. The pathological study of the resected liver showed no cirrhosis but active hepatitis. This arterioportal fistula was probably iatrogenic. Sixteen years before, this patient had undergone a total gastrectomy for cancer, followed by a serious haemorrhage requiring a massive transfusion, which was responsible for the transmission of hepatitis C.
