RESUMO
INTRODUCTION: Ectopic thyroid tissue can be found in many sites. Ectopic thyroid tissue may also be involved in the same processes as normal thyroid gland. These processes include tumors, inflammation and hyperplasia. The appearance of such tissue in rare locations may lead to diagnostic and therapeutic dilemmas. PRESENTATION OF CCASE: We report a rare case of primary papillary carcinoma in an ectopic thyroid in the jugulocarotid regionbased on the bifurcation of the carotid artery, in a 62-year-old woman with history of diabetes and high blood pressure, with a normal thyroid gland. DISCUSSION: The origin of lateral ectopic thyroid tissue is not fully understood and controversial.The lateral localisation is a rare entity and debated extensively in the literature. CONCLUSION: Though rare, the possibility of an ectopic thyroid carcinoma must always be considered by the surgeon in cases of a pathological mass in the neck.
