INTRODUCTION: Ectopic thyroid tissue can be found in many sites, including the tongue, thyroglossal duct, mediastinum, trachea, lung, aorta and abdomen. Ectopic thyroid tissue may also be involved in the same processes as normal, orthotopic thyroid gland. These processes include tumors, inflammation and hyperplasia. The appearance of such tissue in rare locations may lead to diagnostic and therapeutic dilemmas. CASE REPORT: We report a rare case of ectopic thyroglossal thyroid carcinoma in a 63-year-old Caucasian male with a normal orthotopic thyroid gland. CONCLUSION: Although 99% of thyroid cancers develop within the thyroid itself, in rare cases a carcinoma can arise in ectopic thyroid tissue located in the neck or in other areas of the body. 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.
