Abstract
This case report has described a case of papillary carcinoma of thyroglossal duct in a young male. This patient was admitted with a mass in the anterior neck for 2 years. Preoperative Bultrasonography, CT and MR showed a subcutaneous cystic mass with irregular calcification shadow in the central region of the neck without obvious enhancement. Initial diagnosis was thyroglossal duct cyst, and was excised by Sistrunk under general anesthesia. The postoperative pathological examination showed thyroglossal duct cyst combined with thyroid papillary carcinoma, which was confirmed by immunohistochemistry as thyroglossal duct papillary carcinoma.
