Hepatocellular carcinoma eats medullary thyroid carcinoma, a case of tumor-in-tumor metastasis

Endocr J. 2011;58(9):801-5. doi: 10.1507/endocrj.ej11-0052. Epub 2011 Jul 14.

Abstract

Carcinoma metastasis to the thyroid is uncommon, but may be increasing. We describe here a patient with a metastasis of hepatocellular carcinoma (HCC) presenting within a medullary thyroid carcinoma (MTC). The thyroid tumor was detected synchronously with the hepatic lesion by FDG-PET imaging, and HCC metastasis within MTC was confirmed by histological analysis of the thyroid gland.
