[Carcinoma arising in thyroglossal duct cyst: presentation of a new case and review of the literature].

Carcinoma arising in thyroglossal duct remnants is a rare even that appears in about 1% of all surgically treated cases. A survey of the literature reveals more than 100 reported cases. We present a new case of malignant transformation of thyroid remnants in thyroglossal duct cyst wall: a non invasive papillary carcinoma. Local resection by the Sistrunk method, without any other treatment, was considered curative. We also review the available literature regarding this entity.
