[Cardiac metastasis from primary anaplastic thyroid carcinoma]

Cardiac neoplasms are rare entities in the clinical practice. Cardiac metastatic involvement is 20 to 40 times more frequent than the primary form, representing 95% of all cardiac tumors; however, they are frequently underdiagnosed because of their clinical and oncologic features. In this report, we present two cases of cardiac metastasis from primary anaplastic thyroid carcinoma: a 69-years-old woman with right ventricular metastasis and a 61-years-old man with right atrial metastasis. Both patients died during their hospitalization and one of them underwent an autopsy.
