Abstract:
Purpose: To report 2 cases of papillary thyroid carcinoma occurring in a thyroglossal duct remnant, and to discuss the diagnostic and therapeutic methods by reviewing the literature. Methods: An asymptomatic midline mass occurring in the upper neck was the sole presenting complaint in 2 cases. The preoperative evaluation included a complete head and neck examination, B-ultra sound examination and FNAB. The Sistrunk procedure was done. A lobectomy( case 1) and a lumpectomy ( case 2) were performed respectively, because of the abnormality found in their thyroid gland. A modified neck dissection was performed in case 2 because of regional lymphadenopathy. The following histologic studies were carried out on tissues with HE stain. Results: Diagnoses of thyroglossal duct carcinoma were made by several pathologists. Tissues from thyroid were first diagnosed as nodular goiter in case 1 and thyroid adenoma in case 2. In case 2, one positive lymph node and invasion to the hyoid bone was found. Conclusions: Malignant lesions are rare in the thyroglossal duct remnant. The diagnostic criteria is acknowledged. Resection of the thyroglossal duct carcinoma by the Sistrunk procedure is an adequate surgical approach. But the controversy about further treatment will continue because of the lack of large series of patients and the 10 to 20 year follow-up.
