[Late metastasis in thyroid gland after nephrectomy for renal clear cell carcinoma]

Renal carcinoma natural history is unpredictable. Spontaneous metastases regression after nephrectomy, as well as late recurrence are suggestive of this peculiar human neoplasm. tumor metastases localized to thyroid gland are uncommon in clinical practice; and carcinoma of the kidney, breast, lung, melanoma and gastrointestinal tract tumors are responsible for the majority of them. This paper reports on a patient with metachronous thyroid gland metastases after fourteen years of renal carcinoma nephrectomy, with one year after hemithyroidectomy recurrence on cervical striated muscle followed by surgical excision. Therapeutical aspects are briefly reviewed in literature, emphasizing surgical treatment and the need of all-life follow-up, with more alert attitude toward thyroid gland after renal cell carcinoma nephrectomy.
