A forty-five-year-old female patient presented with
thyroid nodules eight years after radical nephrectomy
for renal cell carcinoma (T2N0M0, grade 2, clear cell
subtype) in the right kidney. Ultrasonography of the
neck showed multiple hypoechoic macronodules.
There was no lymphadenomegaly. During total thyroidectomy
following an initial diagnosis of multinodular
goiter, frozen section analysis was made, which
showed metastasis from renal cell carcinoma.
Immunohistochemical studies demonstrated that the
tumor cells were negative for thyroglobulin staining.
No recurrences or other metastatic disease were seen
during a follow-up period of 12 months. Although clinically
the thyroid gland is a rare site for tumor metastasis,
this possibility should be kept in mind in patients
with a previous history of renal cell carcinoma.
