Cardiac metastasis from thyroid malignancy is a rare phenomenon, with an incidence of 2%. The metastatic presentation can be simultaneous or subsequent to the diagnosis of primary thyroid malignancy. Even when cardiac tissue has inherent properties to escape tumor seeding, among carcinoma thyroid, follicular and anaplastic subtypes are the most vulnerable for cardiac metastases. Papillary carcinoma thyroid very rarely produce cardiac metastases per se and cardiac chamber involvement is even more a rarity. Only 11 such cases of papillary carcinoma thyroid with cardiac chamber metastases have been reported in the literature. We present here a compilation of these cases along with ours. Our patient presented de-novo with right ventricular mass and outflow tract obstruction. Excision of the mass showed metastatic carcinoma thyroid and subsequently, completion thyroidectomy showed carcinoma thyroid. He received radioiodine ablation postoperatively and is clinically well at 10 months of initial presentation.
