갑상설관 잔유조직에서 발생한 유두상 선암 1례

Thyroglossal cysts are common abnormalities of thyroid development that present as palpable and usually asymptomatic neck masses. The development of carcinoma in a cyst of this type is extremely rare. Since 1915, fewer than 100 cases have been reported.

Authors report 1 case of thyroglossal duct carcinoma in 25-year-old female patient. Comparing with the common thyroglossal duct cyst, the mass was larger and harder, and had irregular surface. Thyroid scan, fine needle aspiration biopsy and MRI were included as the preoperative evaluation. Wide local excision of the mass including the overlying skin with the bilateral supraomohyoid neck dissection was done and postoperative radiotherapy(5040 cGy) was taken. The patient has been followed for 5 months without evidence of recurrence.
