Metastatic Renal Cell Carcinoma to the Thyroid Gland / 대한내분비외과학회지

ABSTRACT

A 53-year-old female presented with a left-sided thyroid nodule 18 years after left nephrectomy. She did not remember the cause of the nephrectomy and the medical records were all lost. On examination there was non-tender, firm and fixed mass lesion on the left thyroid area. Fine needle aspiration of the nodule revealed carcinoma of the clear cell type. A well-enhanced 2 cm sized mass was detected at the pancreas tail on the abdominal CT. She underwent distal pancreatectomy for the pancreas lesion and both left lobectomy and isthmectomy for the thyroid mass. Intraoperative frozen biopsy revealed both masses as clear cell carcinoma of the same type. She was discharged on the 11th postoperative day and no other treatment such as chemotherapy and radiation therapy was done. At 6 month follow up, she was healthy without any evidence of recur-rence.
