A Rare Thyroid Carcinoma in Ectopic Thyroid Tissue

Thyroglossal duct remnants are the most common congenital cystic lesions of the neck. However, a carcinoma arising in these structures is rare and mostly diagnosed on pathological examination after surgery. This is a case report of a patient with a mid-line cervical mass to whom Sistrunk procedure had been performed and was found to be a papillary thyroid carcinoma without a normally located thyroid gland.
