“…El conducto tirogloso une la glándula a la lengua durante el descenso, para desaparecer al final de la embriogénesis. Ocasionalmente permanecen restos celulares epiteliales del conducto o tejido tiroideo, lo que puede dar lugar a la persistencia del conducto, estimada en 7% de la población adulta 4 , a la formación de un quiste de conducto o a tejido tiroideo ectópico. La falta de obliteración del conducto y la acumulación de la secreción que el epitelio produce, determinan la formación del quiste al distender el conducto.…”

Thyroglossal duct cyst is the most common congenital anomaly of thyroid gland development. However, papillary carcinoma is described only in 1-2% of cases and the clinical appearance is indistinguishable from a benign thyroglossal duct cyst. We report two females aged 15 and 27 years consulting for a cervical mass. In both, a solid cystic lesion was found and excised using the Sistrunk procedure. The biopsy disclosed a papillary carcinoma in both. The postoperative evolution of both patients was uneventful (Rev Méd Chile 2008; 136: 1169-74 E l quiste del conducto tirogloso (QCT) es una de las alteraciones más frecuentes en el desarrollo de la glándula tiroides y una de las principales causas de tumor en cuello, en niños 1 .

A 34-year-old female with papillary carcinoma of the thyroid originating in a thyroglossal cyst is described. The patient’s chief complaint was a submental mass. The mass was 6 × 4 cm, elastic, soft, and smooth-surfaced. CT examination showed high-density areas in part of the interior of the mass. Resection of the mass was attempted with a diagnosis of thyroglossal cyst. Since papillary carcinoma of the thyroid was noted in the cyst by intraoperative frozen section pathological examination, primary carcinoma of the thyroid was suspected, and the thyroid and surrounding areas were examined. Since no abnormalities were noted in the thyroid, the thyroid was preserved. According to the following reasons, the tumor was considered to be primary papillary carcinoma of the thyroid arising in the thyroglossal cyst: (1) Scar formation was noted in the center of the tumor; (2) tumor cells partly infiltrated into the surrounding tissues, and (3) no tumor was noted in the thyroid. A definitive diagnosis of carcinoma arising in the thyroglossal cyst has required confirmation of the absence of carcinoma in the thyroid by total thyroidectomy. In the present case, however, total thyroidectomy was avoided, because no gross pathological changes were observed in the thyroid during the operation. This decision may be controversial both diagnostically and therapeutically, but we consider from our observation of the course that total thyroidectomy is not always necessary.
