Complications of the mediastinal tumors and cysts are malignant change, infection, bleeding, local invasion and mass effect to heart, lung and other mediastinal structures. But early surgical excision and proper treatments bring patients to good clinical course and results. Therefore mediastinal tumors and cysts are surgically interesting diseases We report the analysis of the 58 cases of mediastinal tumors and cysts, experienced in the Department of Cardiothoracic Surgery of the Kosin Medical College from July 1979 to June 1989. The results were as follows ; Sex ratio of male to female to female was 1.3: 1. Range of age was from 11 to 64 years and mean age was 34.3 years. The thymomas were 14 cases[24%], the teratomas were 19 cases[33%o], the neurogenic tumors were 10 cases[17%], the cysts were 9 cases[15%], the carcinomas were 3 cases[5%], the thyroid tumor was 1 case[2%], the Castleman’s disease was 1 case[2%] and unclassified tumor was 1 case[2%]. Malignant tumors were 12 cases [21%] of the 58 cases. Most frequent symptom was chest pain and discomfort and relationship of symptom and malignancy was significant. Complete removal of tumor was performed on the 47 cases[92%] and partial excision was 3 cases[6%]. Inoperable cases were treated with anticancer chemotherapy and radiotherapy. Postoperative complications were wound infection, Homer’s syndrome, phrenic nerve palsy, mediastinal hematoma and pleurisy. There was no case of postoperative mortality and good clinical course in surgically completely resected cases.

For the purpose of analysis of clinical and pathological characteristics in mediastinal tumors and cysts, 82 patients with mediastinal tumors and cysts treated in the department of thoracic and cardiovascular surgery in Chosun University Hospital during the period from January 1978 to December 1994 were reviewed. There were 49 male and 33 female patients in the study. Age ranges from 10 months to 84 years, with the mean 37.2 years. Frequently encountered symptoms and signs were dyspnea[40.2% , abnormal breathing sound[37.8% , chest pain[35.7% , cough[26.8% , and 18.2% of patients were asymptomatic. The most frequent tumor was anterosuperior mediastinum [59.8% followed by middle[24.4% and posterior mediastinum[15.8% . The malignant tumors were found in 35 cases[42.7% . Successful removal of the mass was possible in all the benign mediastinal masses[57.3% . But in the malignant cases, the surgical removal was possible in 18 cases and other inoperable cases were treated by radiation and chemotherapy. The postoperative complications occurred in 9 cases. Usual complications were bleeding[4 cases , wound infection[3 cases , pneumothorax[1 case and vocal cord paralysis[1 case . In the pathologic viewpoint, teratodermoid tumors[22.0% were the most frequent tumor followed by thymomas[19.5 , benign cysts[15.8% , lymphomas[13.4% and neurogenic tumors[8.5% .

종격동에 발생하는 부갑상선 낭종은 매우 드문 질환으로 대부분 우연히 발견되어 진다. 수술적 절제가 필요하며, 전 절제가 된 경우 재발은 매우 드물다. 71세 남자 환자로 단순 흉부 촬영상 우연히 발견된 6$\times$5 cm 크기의 우측 상부 종격동 종괴로 내원하였다. 추가 검사 후 수술적 절제를 시행하였으며, 절제된 종괴는 조직학적으로 종격동에 발생한 부갑상선 낭종으로 진단 되었다. 수술 후 재발 없이 4개월째 외래 관찰중이다. 저자들은 종격동 부갑상선 낭종 1례를 치험하였기에 문헌 고찰과 함께 보고하는 바이다.

We report a case of 36-year-old woman with myasthenia gravis (MG) combined with mediastinal leiomyosarcoma (LMS) and Stevens-Johnson syndrome (SJS). She was admitted to ICU with the symptoms of acute onset headache, diplopia, ptosis, dysphagia, general weakness, and respiratory difficulty for several days. Physical examination revealed tachypnea, decreased breath sounds and dullness to percussion in right lower chest. Neurologic examination showed ptosis, diplopia, decreased gag reflexes, and generalized proximal weakness. Laboratory studies revealed increased serum acetylcholine receptor antibodies and positive Tensilon test. Chest CT showed a huge mass in the right middle mediastium but no evidence of thymic enlargement. Mediastinal LMS was diagnosed by ultrasound-guided needle biopsy. The myasthenic symptoms were fluctuated in spite og intravenous immunoglobulin, plasmapheresis, and corticosteroid. During therapy, SJS developed. She died 4 months after the onset of the myasthenic symptoms despite the chemotherapy for LMS.

A case of mediastinal seminoma is presented. A male driver, 27 years old Korean, has been suffered from substernal pain, cough and moderate swallowing difficulty since 5 months prior to this admission. At the time of onset, he visited at a local clinic to find some mass in his anterior mediastinum on chest P-A and lateral X-ray check. Recently, intermittent hiccups with much aggravated dysphagia forced him to visit our hospital, and admitted for radical resection under the impression of anterior superior mediastinal tumor of thymus origin. Median sternotomy was done and total resection of the tumor of 8.0X11.0X3.5cm was done without any specific complication and biopsy of the tumor revealed as primary mediastinal seminoma of the mediastinum. Supplementary prophylactic irradiation therapy was done with a tumor dose of 4,000 rad in 4 weeks after operation. Postoperative hospital course was uneventful and patient was joyful with his occupation for 3 months after discharge.

Many mediastinal masses seen radiologically are clinically asymptomatic. Only 55 to 65 percent of such lesions are asymptomatic, and of these many have only nonspecific symptoms by rupture, infection and pressure of surrounding organs. This report presents one case of a mediastinal teratoma which complicated an empyema. The patient was 7-year-old female and chief complaints were fever, left chest pain and general ache. In her past history, lung decortication and drainage procedure under the diagnosis of an empyema were carried out, 5 years ago, but she had not been improved, And so, explothoracotomy was done. At the time of operation, a mass of adult fist size was placed in the left anterior mediastinum and covered with the mediastinal pleura. Extirpation of the tumor and decortication were carried out and the left lung was remained.

A mediastinal mass was aspirated by fluoroscope-guided fine needle aspiration biopsy in a 47 years old female patient. The first aspiration smears were not diagnostic, because of hemorrhagic background and cell paucity. On the second aspiration, the smears were composed of some clusters of benign epithelial cells in hemorrhagic back-ground. Cells were arranged in mostly solid sheets and tended to form glandular lumina in part. Their nuclei were round and vesicular. Nucleoli were not prominent. These findings were suggestive of benign glandular tissue, which was finally confirmed as mediastinal thyroid gland by open thoracotomy specimen.

종격동 지방모세포종은 미성숙 지방세포에서 발생하는 드문 양성 종양으로 주로 영아기에서 나타난다. 예후는 좋으나 종종 급격히 성장하거나 국소적으로 침범하기도 한다. 본 증례는 전 종격동에 발생한 지방모세포종으로 인해 빈번하게 폐렴이 발생한 3세 여아에 대한 보고로서, 흉부 컴퓨터 단층 촬영에서 심낭과 우측 폐 종격동 흉막 사이에 위치하여 주변장기를 압박하는 지방함유 종괴로 내부에 석회화나 낭성 조직을 함유하지 않았으며 완전 절제 후 병리 조직 검사에서 지방모세포종으로 진단되었다. 현재까지 합병증이나 재발의 증거 없이 외래 추적 관찰 중이다.

A case of bronchogenic cyst associated with a partial pericardial defect is reported. Bronchogenic cysts are not so rare in incidence, but they are more rare when associated with a pericardial defect, the first case being reported by Rusby and Sellors in 1945. Recently, we experienced such a rare case of a bronchogenic cyst with a partial pericardial defect. The patient is a 39-year-old female and she was found to have a left anterior mediastinal mass during routine chest X-ray. During the operation, we detected partial pericardial defect after removal of the mediastinal mass. The pericardial defect was repaired with a Gore-Tex Membrane. The pathological examination of the mass showed a bronchogenic cyst. The patient had an uneventful hospital course.

Tuberculosis is one of the most common chronic disease. While the disease process may involve anywhere of the body, tuberculosis of anterior mediastinum which forming tumor like mass was not recognized commonly. We experienced a surgical case of tuberculous empyema thoracis at anterior mediastinum in 16 year old boy. Preoperatively, he was diagnosed to anterior mediastinal tumor such as teratoma or dermoid cyst by routine study. Operation was performed by midline sternotomy extending over right 4th intercostal space. The mass was elongated football shaped [20x16x15] and markedly adhered to right side of pericardium, upper 8< lower lobe of the right lung. Opening the mass, enormous pus-like material was evacuated and excised segmentally with decortication. Postoperative pathologic diagnosis was tuberculous empyema thoracis and granuloma.
