For the purpose of evaluation of clinical characteristics and histopathological properties in mediastinal tumors, 130 patients with mediastinal tumors treated during the period from 1958 to 1982 were reviewed. Cancers of unidentified primary site of origin, nonneoplastic lesions and the cases with clinical diagnosis only were excluded from this report. There were 69 males and 61 females, and their ages ranged from 2 months to 66 years, with the average age of 31.3 years. 19.2% of patients were younger than 15 years of age. The most frequently encountered tumors were teratodermoids, followed by neurogenic tumors, thymic tumors, benign cysts, malignant lymphomas and miscellaneous tumors in order of decreasing frequency. 75.4% of the mediastinal tumors were benign and 24.6% were malignant. 16.6% of the patients were asymptomatic at admission. There were 2 postoperative deaths with 1.7% of operative mortality rate, and 2 other deaths who were not operated upon, showing overall hospital mortality rate of 3.1%. Postoperative follow up was possible in 84 cases, and there were 4 late deaths.

Congenital cysts of the mediastinum are rare, but interesting lesions. Such cysts are important because they may produce distressing symptoms and because some have a malignant potential. Mediastinal cysts of foregut origin represent an important diagnostic group. Classified according to their anomalous embryonic origins they include pericardial, bronchogenic, esophageal, enteric, and nonspecific cysts. A series of 11 consecutive surgically treated cases from the Dep. of Thoracic & Cardiovascular Surgery in National Medical Center from Oct. 1959 to Dec. 1990, all successfully resolved without mortality. The 8 bronchogenic, 1 enteric, & 2 non specific cysts are included in this series. And 2 of 11 were asymptomatic patients presented. The clinical & pathological behavior of the individual cysts comprise a wide variety of patterns. Proper utilization of the many diagnostic tests available can accurately characterize the cysts. The exact histologic diagnosis, however, is rarely made prior to operation.

Thoracic duct cysts in the upper portion of the diaphragm are mostly found in the neck and are rarely found in the mediastinum. Thoracic duct cysts should be differentiated from other mediastinal tumors or cysts, and surgical treatment is required to avoid the development of chylothorax if the cyst ruptures. Herein, we report the case of a patient with a thoracic cyst located just above the diaphragm that was treated with surgical resection.

Mediastinal tumor are frequently encountered in clinical practice. Hanten, in 1955, reported-2 adult patients with spontaneous rupture of mediastinal dermoid cysts into the pleural cavity and also, Thompson, in 1963, reported 2 child patients with spontaneous rupture of mediastinal teratoma into the pleural cavity. Mediastinal teratomas have also been reported rupture into other contiguous structures, such as the bronchus, aorta, pericardium, SVC and esophagus. This report presents an instance of spontaneous rupture of an anterior mediastinal teratoma into the right pleural cavity of a 43 year old female. Despite variable diagnostic procedures, the true nature of the lesion was not determined until a thoracotomy and window formation was performed for adequate drainage of empyema thoracis. Removal of the teratoma and mediastinal window formation resulted in complete cure.

Cystic hygroma is a cystic tumor developed by lymphatic stasis due to congenital blockage of regional lymphatic drainage. It ususally occurs at neck and axilla. However, in some cases of cervical cystic hygroma, cervical portions of the cysts may extend into the mediastinum. We experienced a case of huge cervico-mediastinal cystic tumor in 11 month old girl presenting a large fluctuating neck mass and severe respiratory distress. Surgical resection was done through combined approach of cervical incision and median sternotomy. Pathological diagnosis was confirmed to cervico-mediastinal cystic hygroma.

Among varieties of the mediastinal tumors, benign developmental cysts [Entergenous cysts] occur about 10% of them. From the primitive foregut, tracheobronchial tree and esophagus develop at 3 weeks of its embryonal age, and bronchogenic cyst arises from accessory or supernumerary lung bud. Usually it remains isolated with surrounding structures, and causes no specific symptoms. But few cases of bronchogenic cysts have fistulous communication with esophagus causing compressive symptoms. We report a case of unusual complicated case of bronchogenic cyst with review of literatures.

The bronchogenic cyst, one of rare congenital cystic disease, was reported occasionally since the first description of Bartholinus in 1678. The increased use of roentgenograms of the thorax and the widening scope of thoracic surgery was made, and much more cases of bronchogenic cysts has been observed. The most common location of a mediastinal bronchogenic cyst was the hilum. The treatment for bronchogenic cyst is surgical resection. Forty eight cases of bronchogenic cysts which were pathologically confirmed, are reported and the related literatures are reviewed.

VATS is now used by many thoracic surgeons and in various anatomic locations such as lung parenchyme, pleura and mediastinum, etc. VATS of mediastinal masses has special characteristics compared to that of other diseases. Those are no positional changes of the mass during collapse of the lung and close proximity of the mass to major vascular structures, nerves and other vital organs. From 1992. July to 1993. August, 10 mediastinal masses were treated with video assisted thoracoscopy. There were five males and five females, ages ranged from 11 years to 65 years with average 37.7 17.7 years old. Of the 10 patients, 4 were bronchogenic cysts, 2 were teratoma, and the others were thymoma, neurilemmoma, pericardial cyst, and thymic cyst. Needle aspiration was done in large cysts and the working thoracotomy[or utility thoracotomy] was done in large solid masses for the purpose of easy dissection, easy handling and easy delivery of the mass. The average operation time were 155.6 6.8 minutes and the duration of air leakage were 1 2.2 days. The duration of the chest tube drainage were 3.3 2.6 days. The lengths of the postoperative hospitalization were 5.1 2.7 days which were shorter than those of 12 mediastinal masses treated with conventional thoracotomy during the same periods [p<0.05]. There was 1 patient converted to thoracotomy because of a bleeding at innominate vein. 3 postoperative complications were occured. Those were persistent air leakage for 7 days, diaphragmatic palsy and hoarseness which were recovered within 1 month. We conclude that mediastinal mass can be excised with video assisted thoracoscopy and the posthospitalization is reduced. But careful attention is required for avoiding injury to major vascular structures, nerves, and other vital organs.

연구 배경 : 종격동 종양과 낭종은 최근 정기적인 건강 검진의 보급 및 진단 수기의 발달로 진단율이 증가하고 있는 추세로 장기간의 경과를 통한 우리나라에서의 특징적인 임상 양상에 대한 연구가 필요하다. 대상 및 방법 : 본 연구는 연세대학교 의과대학 세브란스병원에 입원하여 병리조직학적으로 확진된 환자들을 대상으로 이전 25년 동안의 보고와 1985년 7월부터 2002년 6월까지 최근 17년 동안의 결과를 비교하였다. 결 과 : 전체 종격동 종양 479예 중 흉선종이 183예(382%)로 가장 많았고, 종격동 구획에 따른 분포는 이전 보고와 유사하였다. 흉부 X-선 촬영상 우연히 발견된 경우가 174예(36.3%)로 이전의 보고(10.9%)보다 더 많았다. 악성 종양과의 감별을 위해 시행한 경피세침흡인생검의 전체 진단율은 68.6%이었고 악성 종양에서 80.9%로 진단율이 높았다. 전체 479예 중 수술적 절제를 시행한 환자는 405예(84.6%)이었고, 완전 절제율은 91.1%로 이전의 보고(78.8%)보다 더 높았다. 이전 보고와 본 연구 결과를 종합한 42년 간의 결과는 총 662예 중 흉선종이 205예(31.0%)로 가장 많았다. 결 론 : 종격동 종양과 낭종은 최근 진단율과 완전절제를 통한 적극적인 치료가 급속히 증가하고 있는 추세이며, 특히 흉선종의 비율이 현저히 증가하여 이에대한 관심이 필요하다. 종격동 종양에 대한 경피세침흡인생검(중심침생검 포함)의 전체 진단율이 68.6%이고, 악성 종양에서 80.9%로 높아 수술적절제 전 악성 종양과의 감별을 위한 일차적인 진단법으로 유용하다고 생각된다.
