HERRERA, Francisco et al. Primary papillary carcinoma originating in tracheal ectopic thyroid tissue. []. , 30, 1, pp.62-67. ISSN 2011-7582.

Thyroid carcinoma arising from an ectopic thyroid tissue is an uncommon clinical entity. These lesions usually present as a mass in the midline that develops from a thyroglossal duct remainder. The finding of a malignant lesion in true aberrant thyroid tissue is unusual. Given the strangeness of this condition we present the case of a patient in which the diagnosis conducted a primary papillary carcinoma arising from ectopic thyroid tissue in the trachea.
