In a 55-year-old woman (10 years after subtotal thyroidectomy for
follicular adenoma) echocardiography revealed a 25 x 23-mm tumour in the
right ventricular outflow tract. The successfully removed tumour appeared
to be a follicular carcinoma. Subsequently, there has been no clinical and
laboratory evidence for another site of metastasis or ectopic thyroid. The
whole body 131I scan showed only correct radioiodine uptake in the place of
cervical residual thyroid gland. We believe this is the first description
of follicular carcinoma in cardiac ectopic thyroid.
