Abstract

Papillary thyroid carcinoma (PTC) is a common cancer in the world and in our coun- try. It is usually associated with good prognosis and high survival rates, due to the tumor’s characteristics, precise diagnostic tools and effective therapies. Unusual varie- ties of PTC have more aggressive behaviors and partial responses to usual treatments, such as negative uptake to radioiodine PTC (5% of cases). There is few literature about this variety and its treatment. Diverse treatment options have been proposed, according to whether there is evidence of tumor tissue, such as the empirical use of I131, surgery, radiotherapy, embolization and inhibitors of thyrosine kinase, however an uncertain res- ponse remains.
