Ectopic thyroid mass in the right ventricle: A case report.

Ectopic thyroid is a rare congenital embryonic anomaly. Ectopic thyroid tissue can be located anywhere during its descent, but it is found primarily at the base of the tongue and in the mediastinum. It is very rarely found in the heart. Here, we report a rare case of cardiac ectopic thyroid tissue in a 53-year-old woman who presented with chest pain. Echocardiography revealed an intracardiac mass that was removed successfully. Histopathology confirmed that the mass was thyroid tissue without malignancy.
