Abstract
A 20-year-old male was seen at our institute for the investigation of a 3-cm mass in the midline of his anterior neck. A computed tomography scan and ultrasonography study revealed the presence of a cystic lesion with a calcified papillary mass. A papillary carcinoma arising from a thyroglossal duct cyst was suspected. A Sistrunk procedure was performed for diagnosis and curative treatment. The pathological findings showed a papillary carcinoma arising from a thyroglossal duct cyst with no invasion to the surrounding tissues. Thyroglossal duct cyst is a benign disease that is often recognized as a mass in the anterior neck during daily examination. The condition represents a common developmental abnormality of the thyroglossal remnant and rarely involves a malignant disease. We report the case of a papillary carcinoma arising from a thyroglossal duct cyst.
