저자들은 1982년부터 1987년까지 5년간 서울대학교병원 이비인후과에서 경험한 21예의 갑상설관 낭종에 관한 임상적 관찰을 하여 다음과 같은 결과를 얻었다. 발현 연령은 출생시부터 43세로 다양하였으나 21예중 10례가 10세 이전에 발생하였다. 7예에서는 경부종괴가 주소였으며 4예에서는 누공이 주소이었다. 낭종은 대부분 정중선에 위치하였으며 설골 하부에 위치한 예가 17예이었다. 전례에서 설골 중앙부를 포함한 전 병소를 제거하였으며 현재까지 재발된 예는 없었다.

Thyroglossal duct cyst is the most common congenital neck mass. It develops from remnants of precursors of thyroid gland left behind during embryologic descent form the foramen cecum at the tongue base into the anterior neck during fetal development. An anterior midline neck mass presenting before the age of twenty and displaying vertical movement with tongue protrusion and swallowing is characteristic of this lesion. In this paper, we report on a case of TGDC without remnant duct that is presenting as thyroid cyst.

Thyroglossal duct cyst(TGDC) is the most common midline congenital neck mass in children. However, carcinoma arising from TGDC is very rare and most of them are found in adults. In this report, we describe a 9-year-old child presenting with TGDC, which finally turned out to be papillary thyroid carcinoma. He underwent Sistrunk operation only. We review the literature and highlight the important points of the treatment.

Thyroglossal duct cyst is a congenital anomaly generally appearing as an asymptomatic midline neck mass. Generally, the duct cyst is benign, but 1 percent of cases may be malignant. These present the same histologic types as thyroid carcinomas. The most common pathologic type is papillary carcinoma. Regional lymph node metastasis of papillary carcinomas in thyroglossal cyst occurs in 7.7 percent of cases. Prognosis of papillary carcinoma is excellent. The treatment has been quite variable, but the most common initial treatment is Sistrunk's operation. Adequate excision of cyst and its tract including the mid-portion of the hyoid bone is the treatment of choice. We experienced two cases of papillary carcinoma arising in thyroglossal duct cyst between 1986 and 2002.

A lingual thyroglossal duct cyst(LTGDC) is a rare congenital anomaly that account for only 0.5% to 2% of total thyroglossal duct cyst. LTGDC is frequently associated with respiratory problem in infants and pharyngeal foreign body sensation or dysphagia in adults. Because of its location and characteristics, lingual thyroid, dermoid cyst, and vallecular cyst should be included in differential diagnosis. Standard treatment for thyroglossal duct cyst is sistrunk's operation, but in terms of LTGDC, because of its location and cosmetic reasons, different kinds of treatments such as electrical cauterization, $CO_2$ laser, Robort surgery via transoral approach have been introduced. Recently authors encountered 21 years old woman with LTGDC and the mass was removed successfully via transoral approach using $CO_2$ laser. We report the clinical course with review of the literature.

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 out-patient 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.

An intrathyroid thyroglossal duct cyst (TGDC) presented as an anterior neck mass in a 62-year-old male without history of prior thyroid disease or infection. This cyst was clinically indistinguishable from a thyroid nodule. In addition to that, fine needle aspiration cytology revealed normal-looking squamous cells. Diagnosis, work-up, management approach, and treatment of intrathyroid TGDC are discussed as well as distinguishing features between intrathyrod TGDC with tract and without tract. This is the very rare case of intrathyroid TGDC in Korean population and the possibility of intrathyroid TGDC should remain in the differential diagnosis of thyroid nodule.

The thyroglossal duct cyst is relatively rare disease that derived congenitally from the remnant of thyroglossal duct and that was found anywhere from the foramen cecum to pyramidal lobe of thyroid. We studied the 62 cases of above disease who admitted and operated at E.N.T. dept. of N.M.C. for 20 years since 1961 to 1980 on the clinical and histopathological aspect, and we concluded following results. 1. In the age distribution, 45 cases(72.6%) were under 20 years, and in the age distribution of the known on-set of symptoms, 26 cases(58.0%) were under 10 years. In the duration, 23 cases(37.0%) were under 1 year. The sex ratio of male to female revealed 1.2:1. 2. The palpable mass were complained at 48 cases(77.4%) and 14 cases(22.6%) complained of the discharge from sinus tracts and the other complaints were dysphagia and odynophagia, etc. 3. In location 55 cases (88.7%) were at midline, 1 case(1.6%) was at right and 6 cases(9.7%) were left sided. And 47 cases(75.8%) were situated at infrahyoid region, 11 cases(17.7%) at suprahyoid, 3 cases(4.8%) at suprasternal, only 1 case(1.6%) at intralingual region. 4. In 27 cases formed fistulae, spontaneous occurrance were 7 cases and artificial occurrance were 20 cases. 5. In histopathologically among 41 cases preserving available slides, 5 cases(12.2%) had single duct and 20 cases(48.8%) had multiple accessory ducts, but 16 cases were impossible to detect the ducts. The lining epithelium composed of chiefly respiratory and squamous epithelium. 15 cases had inflammatory reaction at periductal area and 7 cases had around the cysts. The ectopic thyroid tissue was found on 6 cases(14.6%) and 1 case had the follicular adenoma. 6. In the recurrance rate among 43 cases performed sistrunk type operation, 2 cases (4.6%) recurred, and among 19 cases performed simple removal of cysts, 4 cases (21.1%) recurred.
