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.

50세 여자가 전흉부의 통증을 주소로 내원하였다. 흉부단층촬영에서 우상엽을 침범하고 있는 전종격동의 종괴가 발견되었으며, 수술로서 완전절제하였다. 조직검사에서 악성 흑색종을 진단할 수 있었고, 원발병소의 가능성이 있는 피부, 구강, 안저, 비강, 직장, 항문, 질 등을 각각의 전문의에게 검사를 받았으나 이상소견이 없었다. 원발병소가 자연적으로 소멸된 경우가 아니라면 종격동에 원발한 악성 흑색종이라고 생각된다. 종격동에 발생하는 악성 흑색종은 아주 드문 질환으로 세계적으로 8례만이 보고되고 있고, 한국에서는 아직 예가 없기에 보고하는 바이다.

A wide variety of histologically or clinically different tumors and cysts can occur from the many anatomical structures located within the mediastinum. We report the analysis of the 26 cases of mediastinal tumors and cysts, experienced in the Department of Thoracic and Cardiovascular Surgery, College of Medicine, Hallym University from March 1983 to February 1990. Sex ratio of male to female was 1:1.16 and mean age was 33.4 years. Malignant tumors were 8 cases[30.7%], benign tumors were 18 cases[69.2%] The most common histologic types were thymoma, 6 cases[23%] and teratoma, 6 cases [23%] followed by neurogenic tumor, 4 cases[15%] and mediastinal tuberculoma, 3 cases [11.5%]. The most frequent symptoms were chest pain and discomfort. Most of benign tumors were completely removed and malignant tumors were treated with anticancer chemotherapy and radiotherapy after operation. Postoperative complications were developed in 4 cases[15.3%] and hospital mortality was 3.8%.

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.

A rare benign tumor of the pericardium was found in a 47-year-old woman with epigastric discomfort. She was initially thought to have an anterior mediastinal tumor but was proved to have a massive intrapericardial lipoma without malignant condition. The tumor was measured 26X20X5 cm in size and 2,200 gm in weight. Calcifications and necroses were found around the three pedicles. The tumor was removed easily by dividing the pedicles. With the brief review of literature, we report the case.

Malignant melanoma develops from the melanocyte and the most common primary site is skin, followed by mucosa and retina. Even though any other tissue where melanocytes reside could be the primary site of the malignant melanoma, the one developed in the mediastinum is rarely reported. We experienced a patients of 54 years old woman whose initial symptom was progressive dyspnea for one month, and proved to have the anterior mediastinal mass with pleural effusion and the small mass in the abdominal soft tissue. The needle aspiration biopsy from the mediastinal mass showed the consistent findings with malignant melanoma. We concluded the mediastinum was the primary site of the malignant melanoma of this patient because we couldn't find any other evidence of primary tumor in skin, oral and gastrointestinal mucosa, and retina. She has been treated with combined chemotherapy with dacarbazine, cisplatin and vinblastine. Her symptom was improved after chemotherapy and follow up chest CT after three cycles of chemotherapy showed the decreased tumor size in the mediastinum.
