For many years it has been reported that seemingly benign neck cysts may contain carcinoma. Cystic metastases have often mistaken for either branchial cleft cysts or benign mass. Authors experienced two cases which presents cystic cervical metastatic cancer One was a tonsillar carcinoma and the other was a tongue carcinoma. Patients with a cystic squamous carcinoma in the neck likely have a primary in upper aero-digestive system and It is known that the tonsil is most common site. Radiologic examination and fine needle aspiration biopsy of the cyst proved to be non-diagnostic. The development of cervical lymph node metastases before clinical signs of carcinoma of the tonsil is also well recognized. So, in old patients, thorough head If neck examination, panendoscopy and ipsilateral tonsillectomy is mandatory to identify a primary carcinoma prior to cyst excision.

The fourth branchial clef cyst is very rare entity ana only 35 cases have been reported worldwide. There have been some controversial attempts to prove its anatomical route through embryological background. However some reports even suggested that it might be impossible to prove its entity anatomically Recently, reports are coming out on the diagnostic approaches using anatomical pathway. We experienced in 45 years old woman, one case of lateral cystic neck mass which were anatomically presumed to be fourth brachial cleft cyst.

Thyroglossal duct cysts are the most common anomaly in thyroid development. Generally, duct cysts are benign, but 1 per cent of cases may be malignant. Tumors of the thyroglossal duct are very rare and are usually papillary thyroid carcinomas. In most cases the diagnosis is only established after excison of a clinically benign thyroglossal duct cysts. The etiology of such tumors is unclear, but do novo origin and spread from a primary thyroid gland tumor has been suggested. We reported a case of papillary carcinoma arising in a thyroglossal duct cyst treated successfully with surgical excision in 37-year-old-female.

Bronchogenic cysts are uncommon congenital anomalies and commonly located in the mediastinum or lung parenchyma. Bronchogenic cyst in cervical area is rare and in posterior pharyngeal area is exteremely rare. Clinically, it is usually asymptomatic and incidentally diagnosed. It is pathologically confirmed only when there are bronchial tissues such as pseudostratified ciliated columnar epithelium, smooth muscle cells, mucous gland and/or cartilage. Since it has potential for malignant transformation and complication, complete excision is essential. We report a case of bronchogenic cyst located in the retropharyngeal space with a review of literature.

구치부 매복은 1% 이내로 드문 편이지만 저위 교합, 반대 악궁 치아의 정출, 인접치 경사로 인한 공간 부족 등의 문제가 발생하게 된다. 구치부 치아는 교합 및 악골 발육에 관여하는 기능적으로 중요한 치아이므로 초기 혼합 치열기부터 지속적인 방사선 사진을 찍어 매복 여부를 관찰해야 한다. 매복의 원인에는 치근 발육의 저하, 과잉치, 낭종, 치아종, 유착 등이 있다. 첫 번째 증례에서는 초진 시 치근 발육이 1/2이하라서 자발적 맹출을 기대하였지만 2/3이상 발육 시에도 맹출 하지 못하여 외과적 노출 및 교정적 견인을 시함하였다. 두 번째 증례는 낭종을 포함하는 매복 구치를 주소로 내원하였고 낭종 크기가 작고 인접 부위에 주요한 해부학적 구조물이 없어 완전한 적출술을 시행 후 교정적 견인을 하였다. 교정적 견인 시 해당 치아에 직접 어태치먼트(attachment)를 붙인 후 악하고 지속적인 힘을 적용하는 것이 유착, 외흡수, 치주 부착 소실 등의 부작용이 나타나지 않는다. 또한 고정식 장치를 사용하면 환자의 협조도가 필요 없고 맹출 공간을 확보하면서 호선상에 매복치를 견인 할 수 있다. 본 증례에서는 매복 구치를 외과적 노출 및 교정적 견인을 통해 교합상으로 배열을 하여 양호한 결과를 얻었기에 보고하는 바이다.

Esophageal duplication cyst is very rare mediastinal tumor which is congenital lesion of the esophagus. Esophageal duplication cyst could be excised with video assisted thoracoscopic surgery(VATS) if it is relatively small, cystic lesion and not adhered severely to the surrounding tissues such as lung, trachea, bronchus, esophagus and pleura. We report a case of an esophageal duplication cyst which was located in the right thoracic cavity below carina and could be excised completely and repaired by interrupted suture with 3.0 black silk. The patient was discharged at 10 days after operation with good condition and has been in uneventful condition 2 months after operation.

치성낭종과 법랑아세포종과의 조직학적 기준이 모호한 경우에 과거에는 병리학자들이 진단하는데 어려움이 많았으나 1970년 Robinson & Martinez가 조직학적 기준을 제시하면서 unicystic ameloblastoma라 명명하였다. Unicystic ameloblastoma는 conventional ameloblastoma 보다 젊은 연령인 10대, 20대에서, 하악 제3대구치부에서 호발하며 방사선학적으로 단방성 혹은 다방성의 비교적 경계가 뚜렷한 방사선 투과성 병소를 보인다. 이 병소는 적출술만으로 치료하였을 때 solid or multicystic ameloblastoma보다 현저히 낮은 재발율을 보인다. 임상적, 방사선학적으로 unicystic ameloblastoma가 의심되면 병소를 완전히 적출하여 정확한 병리조직학적 진단을 하여 solid or multicystic ameloblastoma일 때는 2차적으로 광범위한 수술 등을 고려하는 것이 타당할 것으로 사료되어 문헌고찰과 함께 3증례의 치료 경험을 보고하는 바이다.

Thymic cysts are uncommon tumors which usually occur in the neck and mediastinum. It is known to arise from embryonic remnants of the thymopharyngeal duct or from inflammation of thymic tissues. Patients with thymic cyst are often asymptomatic and identified after surgical removal and histologic examination. We experienced a 73 year-old man with recently developed dyspnea. During the examination, chest CT showed a $5\times6cm$ sized cystic mass causing deviation of the trachea. It was located in between the right thyroid gland and anterior mediastinum. It also caused tracheal narrowing noted by bronchoscopy. Right anterior cervical incision and removal of the mass was performed and a histological diagnosis of thymic cyst was confirmed. The patient was discharged without complication.

This is to report a case of bronchgenic cyst. While most of the bronchogenic cysts reported in the literature so far were located either in the lung parechym or in the mediastinum near the tracheal bifurcation or main bronchi. the cyst presenting in this study was originated in the wall of the esophagus and was reported to be very rare. The cystic tumor was found accidentally by X-ray fluoroscopic examination of the esophagus and stomach in the patient with gastric hemorrhage. X-ray study revealed that the cystic tumor was oval in shape and located in the left posterolateral wall of the esophagus in the thoracic lower third. Two surgical operations, gastrectomy for gastric hemorrhage and the resection of the cystic tumor, were carried out separately. Gastrectomy including the removal of prepyloric ulcer by the Billroth II type procedure was performed in regular fashion, and the cystic tumor was resected radically without any injury of the mucous membrane of the esophagus. The cyst removed appeared to be filled with mucinous material, and histological examination identified the tumor as a bronchogenic cyst with ciliated epithelial internal lining. Postperative course of the patient was uneventful.

Bronchogenic cysts are rare congenital anomalies of the tracheobronchial tree. Most cases present within the mediastinum or pulmonary parenchyma without a patent connection to the tracheobronchial tree or digestive tract in the pediatric age group. Cervical bronchogenic cysts in adults are rare. In this report, we describe two cases of incidentally found paratracheal bronchogenic cysts that presented as asymptomatic neck masses in a 66-year-old female with papillary thyroid carcinoma and in a 59-year-old male of Catleman's disease.
