title: [Follicular carcinoma of the thyroid manifested initially as asymptomatic primary renal neoplasm].
abstract: Metastases in the kidney are rare, evenmore if primary source is thyroid. We report the tenth case of metastases in the kidney from thyroid, and it is the first to be follicular type and absolutely asymptom. Sonography and computerized tomography with suspicion of renal tumour are showed in a asymtom female 75 years old. Left partial nephrectomy was perfomed, initially it has been pathologically diagnosed as renal clear cells tumour, however the definitive pathologic report showed follicular tumour of thyroid. Local and systemic stage was discovered with complementary techniques. Sources of metastases in kidney and diagnoses techniques are discussed.
