title: Cardiac metastasis from primary anaplastic thyroid carcinoma: report of three cases and a review of the literature.
abstract: BACKGROUND
  Clinically evident cardiac metastases from malignant neoplasms are uncommon. The frequency of thyroid metastasis to the heart is very low. To our knowledge, over the last 20 years only a few cases have been reported in the entire literature. Metastatic cardiac involvement occurs most often during the terminal stage.
  
  
  METHODS
  We present three cases of anaplastic thyroid cancer with metastatic involvement of the heart.
  
  
  RESULTS
  Two of the patients died from cardiac problems. The absence of early symptoms makes the clinical diagnosis of metastatic carcinoma difficult.
  
  
  CONCLUSIONS
  Anaplastic thyroid cancer is an aggressive cancer with a dismal prognosis. It should be borne in mind as a source of cardiac metastasis and a cause of cardiac death.
