The mediastinoscopy was a well known useful diagnostic tool for detection of mediastinal lymph nodes invasion by bronchogenic carcinoma, and also useful means for histologic diagnosis of metastatic carcinoma and certain mediastinal tumors. 31 cases of mediastinoscopies were reviewed which were experienced at Kyung Hee University Hospital from July, 1979 to June, 1985. We experienced 20 cervical mediastinoscopies, 10 left anterior mediastinotomy, and 1 both procedures. Of the 31 cases, 22 cases were used for preoperative staging of bronchogenic carcinoma, 7 cases for mediastinal tumor diagnosis, and 2 cases for histologic diagnosis of metastatic carcinoma. In 22 mediastinoscopies which were used for preoperative staging, 10 cases were revealed positive mediastinal nodes, and could avoid meaningless thoracotomy. All 12 mediastinoscopy negative patients were received thoracotomy, and 10 of them were resectable. The resectability in bronchogenic carcinoma was 83%, on the contrary, the other series at premediastinoscopic era revealed only 65% resectability. Other mediastinal lesions such as tuberculous granuloma [4], sarcoidosis [2], malignant thymoma [1], and metastatic carcinoma [2] were also diagnosed successfully. Mediastinoscopy is very useful tool for determination of treating method of bronchogenic carcinoma, and for diagnosis of certain mediastinal tumors which, otherwise, need a thoracotomy for confirmatory diagnosis.

We have experienced 47 cases of primary mediastinal tumors & cysts in the Department of Thoracic and Cardiovascular Surgery, Chonbuk National University Hospital, from September, 1979 to November, 1990. The results were as follows: 1. The age distribution was from 6 months to 69 years old and the mean age was 32.3 years old. Of all 47 primary mediastinal tumors and cysts, 21 patients were male and 26 patients were female. 2. The neurogenic tumors[11 cases, 23.4%] were most frequently encountered and followed by thymoma[10 cases. 21.3%] and teratodermoid[9 cases, 19.1%]. 3. The anterosuperior mediastinum[59.6%] was most common tumor location, and followed by posterior mediastinum[25.6%], middle mediastinum[14.9%]. 4. The most common tumors were thymoma and teratodermoid at anterosuperior mediastinum, benign cyst at middle mediastinum, and neurogenic tumor at posterior mediastinum 5. The malignant tumors were 10 cases[21.3%] of the 47 cases and they were all symptomatic. 6. The most common chief complaint at admission was chest pain or discomfort[34%], and followed by coughing[23.4%], and dyspnea[17%]. 7. The successful complete removal was done in 37cases of benign tumors and cysts. In malignant cases, the surgical intervention was done in 3 cases, and 6 cases were treated with irradiation and chemotherapy, and 1 case was only biopsied. 8.

Thoracoscopy, mediastinoscopy and/or mediastinotomy and explo-thoracotomy were performed and confirmed diagnosis of the 26 cases of the mediastinal tumors, those were admitted and treated at the Department of Thoracic and Cardiovascular surgery, Chonbuk National University Hospital, from June,1976 to September, 1986. We experienced 7 thoracoscopies, 7 mediastinoscopies &/or mediastinotomies, and 12 explo-thoracotomies. The most common histologic type was teratoma and lymphoma [6 cases]. Of the 26 cases of the histologically confirmed mediastinal tumor, 19 were benign tumors and 7 were malignants. 19 cases of benign tumors were surgically resected with good result but one case of the surgically resected malignant thymoma was recurred 4 months later. 6 cases of malignant lymphoma and one case of recurred malignant thymoma were treated with chemo-and radiation therapy. Thoracoscopy and mediastinoscopy with tissue biopsy were simple in procedure and had a tissue diagnosis with obtaining the pathologic tissue in a acceptable complication rate and reduced exploratory thoracotomy.

This report is an review of 40 cases of mediastinal tumors which were treated surgically in the Department of Thoracic and Cardiovascular Surgery, Chonnam University Hospital from January, 1985 to September, 1989. In this series, male to female sex distribution was 1.35:1 with the male predominant. The main clinical manifestations were chest pain and dyspnea, and there was no definitive symptom in 5 cases [12.5 %]. The most common mediastinal tumor was thymoma, 11 cases [27.5 %], and next common mass was germ cell tumor, 9 cases [22.5 %]. The half of these were malignant. In operating, all of the benign masses were removed.

Thymolipoma is a rare benign mediastinal tumor, composed of mature fatty and thymic tissues. A 9-year-old boy was referred with a one-month history of neck swelling. Preoperative computed tomography scan and fine needle aspiration biopsy suggested thymolipoma. Despite it being rare, thymolipoma should be considered in the differential diagnosis of mediastinal tumors. Characteristics of its clinical feature and radiological findings that can differentiated it from other mediastinal tumors are discussed with a review of the literatures.

We have experienced two cases of video thoracosopic excision of mediastinal tumors at the department of thoracic and cardiovascular surgery, Yonsei University, College of medicine. Histologically the mediastinal tumors were cystic thymoma in one & bronchogenic cyst in another. The operative times were rather short and the post-operative courses were not eventful. These patients were discharged with less chest discomforts in post-operative 5 days & have been in good conditions to now.

A retrospective analysis was performed on 36 patients with primary cysts and tumors of the mediastinum seen at the Department of Thoracic and Cardiovascular Surgery of Maryknoll Hospital from January 1983 to December 1993. There were 21 female and 15 male patients in the study. Ages ranges from 2 years to 72 years, with a mean of 34.7. There were 9 malignant tumors and 27 benign tumors.Thymic neoplasms were the most common. For the whole series, 29 of the patients had tumors in the anterior mediastinum. There appears to be an in6rease in tumors in the anterior compartment. There were 30 symptomatic patients in our series. Of the patients with malignant disease, 89 % were symptomatic. All of benign tumors were completely removed and malignant tumors were treated with chemotherapy and radiotherapy after operation. There were 9[27.3 %] postoperative complications. There was no postoperative mortality. Follow-up was available on 27 patients. There was no recurrence, malignant degeneration, or growth of any tumor. It is hoped that careful evaluation and aggressive treatment of mediastinal tumors will continue to provide improvement in the prognosis for these patients.

Generally early surgical extirpation is considered to be beneficial for the treatment of mediastinal tumors and prevention of its complication. The review of the clinical course, histopathologic characteristics and current diagnostic and treatment modalities will help us to decide when to treat and how to treat mediastinal tumors. For this purpose clinical analysis of the 42 patients who were surgically treated from July 1984 to August 1993 in the Chung Ang University Hospital is done in this report. There were 24 males and 18 females[1.3:1], and their age ranged from 1 year to 75 years. Nonspecific symptoms such as chest pain, cough and dyspnea were the most frequently encountered symptoms. Asymptomatic patients were relatively common[21.4%]. The tumors were found most frequently in the posterior mediastinum[45.2%]. Anterior mediastinum was the next and middle and upper mediastinum showed relatively rare occurrence of the tumor. Neurogenic tumor was the most common histopathologic type . Germ cell tumor, benign cyst and thymoma followed it. Curative resection was possible in 27 patients[64%], partial resection in 6 patients[14.3%]and just open biopsy in 7 patients[16.7%]. There was no early operative mortality. Postoperative complications were occurred in 5 patients[11.9%] and most of them were not serious.

This is a report on a total of 8 cases of benign mediastinal tumors and cysts in Department of Thoracic Surgery, Chonnam University Hospital during the period from 1961 to 1969. The patients age was distributed between 18 and 38 year old with the highest incidence in the age group of second decade. Sex ratio of male to female was 3: 5. The tumors were classificed as follow; 3 case:, of neurogenic tumors, 2 cases of teratomas, one case of pericardial cyst, one case of cystic hygroma, and one case of brochogenic cyst. The symptomatic patients were 5 cases(62. 6%) and asymptomatic patients were 3 cases(37.5%). The symptomatic patients had the symptoms not referable to their lesion and the mediastinal tumors of asymptomatic patients were incidently found by routine chest X-ray. The Symptoms occurred by compression to adjacent nerve system in 3 cases. by perforation into the lung with infection in one case and by infection of bronchial cyst in one case. The complications were Pancoast's syndrome including Horner's syndrome(2 cases), middle lobe syndrome (one case), bro:1chial infection(one case) and intercostal neuralgia(one case). All tbe tumors were surgicai[y resectable with good recovery postoperatively. In 5 cases of the symptomatic patents, their symptoms were disappeared dramatically after operation.
