ABSTRACT

Introduction: Thyroglossal tract cyst (TTC) is the most common form of congenital anomaly of the thyroglossal tract. Papillary carcinoma on ectopic thyroid tissue in the thyroglossal tract is rare (less than 1%), and usually the diagnosis is made postoperatively as it clinically presents as TTC. In this work we report a rare case of ectopic papillary thyroid carcinoma at the thyroglossal tract of a 38 years old woman, resected by the Sistrunk procedure. After diagnostic confirmation by histological examination a total thyroidectomy was done. This was followed by complementary treatment with ira-therapy.
