title: [Papillary carcinoma in a thyroglossal duct cyst: report of two cases].
abstract: 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.
