초록

A thyroglossal duct cyst (TGDC) is the most common congenital anomaly of the neck. However, carcinoma arising from TGDC is extremely rare. We report 2 cases of TGDC carcinoma. In the first case, a 21-year-old male patient complained of an anterior cervical mass; computed tomography (CT) and sonography revealed cystic mass that was suspected to be a TGDC. Sistrunk operation was performed. Papillary carcinoma was confirmed in pathologic examination. Additionally, he underwent total thyroidectomy and central neck dissection. After radioactive iodine ablation (RAI) was performed. In the second case, a 28-year-old male patient visited our outpatient department complaining of submental mass. He had already been diagnosed TGDC carcinoma 13 years ago and had undergone Sistrunk operation and total thyroidectomy. Malignancy was confirmed using fine-needle aspiration; thus, lateral neck dissection was performed and following this, he underwent RAI. Till date, no evidence of recurrence has been observed in these patients.
