Metastases to the thyroid gland represent a rare event. Malignancies that most frequently metastasize to the thyroid vary between clinical and autopsy studies and by geographic area. In Western countries, renal carcinoma has been recorded as a frequent source of thyroid metastases. We report the case of a 66-year-old man with a thyroid metastasis from clear cell renal carcinoma and discuss its clinical, pathological and imaging features.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
