ISOLATED METACHRONIC METASTATIC CLEAR CELL RENAL CELL CARCINOMA IN THE THYROID GLAND 7 YEARS AFTER NEPHRECTOMY.

Thyroid gland is a rare site for distant metastases. The aim of this study is to present a rare case of an isolated metastatic clear cell renal cell cancer (ccRCC) in the thyroid gland seven years after left-sided nephrectomy. A neck cancer discovered by clinical examination, diagnosed by ultrasound -guided USG fine-needle biopsy was removed by surgery. Palliative thyroidectomy with consecutive neck radiotherapy was finished without any complications, except a temporary, asymptomatic hypocalcaemia. After six month remission, the patient's general condition deteriorated, multiorgan RCC dissection appeared leading to the patient's death. [ABSTRACT FROM AUTHOR]
