  To the Editors: This is a singular case of the simultaneous occurrence of medullary thyroid cancer (MTC) and 2 metastatic nodules of renal cancer cell (RCC) in the thyroid gland of a 66-year-old female. In 2017 our patient underwent right nephrectomy for an RCC, clear cell type (Union for International Cancer Control [UICC] staging pT1a, Fuhrman grade 3, and G3 by ISUP-WHO 2016). Radiological thyroid cancer follow-up was negative for secondary lesions. Moreover, she suffered from primitive hyperparathyroidism and 99mTc scintigraphy individuated pathologic upper right parathyroid gland.
