title: Thyroid gland metastasis from renal cell carcinoma masquerading as nodular goitre.
abstract: Renal cell carcinoma metastasizing to the thyroid gland, in a 72 year old Japanese woman, is reported. The patient had undergone a left radical nephrectomy for renal cell carcinoma 3 months prior to the present operation. The patient noticed a nodular goitre but there was no evidence of any systemic spread of renal cell carcinoma. The histopathologic diagnosis, from a left lobectomy of the thyroid gland, was thyroid gland metastasis from renal cell carcinoma in adenomatous goitre. Clinical manifestation of thyroid gland metastasis from renal cell carcinoma, with no evidence of systemic involvement, is seen rarely. A case is reported and the condition discussed briefly.
