Author made a clinical study of 48 cases of primary mediastinal tumors experienced in the dept. of the thoracic and cardiovascular surgery of Pusan National University Hospital during the 12 years period from march 1978 to march 1989. There were 34 males and 14 females. Their age distribution was from 4 months to 70 years, with the mean age of 34.4 years. 8.3 % of the patients were younger than 15 years old. There were teratoma 14 cases[29%], thymoma 11 cases[23%], neurogenic tumor 10 cases[21 %], lymphoma 6 cases[13 %], benign cyst 6 cases[13 %], and one case of fibrous histiocytoma in the histological distribution. The malignant tumors were 12 cases[25 %]. The common symptoms were chest pain and discomfort[35.4], coughing[18.8], general weakness and dyspnea. 16.7% of the patients were asymptomatic at admission. The successful removal was done in all cases of benign mediastinal tumors. In malignant cases, the surgical removal could be done in 5 cases. There was not postop. mortality. The frequent complications were atelectasis, infection, bleeding.

Approximately 9.8% of neurogenic tumors of the mediastinum extend into the spinal column so that the composite neoplastic mass was dumbbell shaped. We experienced three patients confirmed by Dumbbell shaped mediastinal tumor radiologically and tried surgical resection by posterolateral thoracotomy only corpectomy and costotransversectomy was performed simultaneously in three patients and interbody fusion in two. In one patient the diagnosis was liposarcoma and in 1 neuroblastoma and in 1 neurilemmoma. then followed by radiation theraphy in case I and radiation and chemotheraphy in case II. All three cases showed satisfactory results clinically and radiographically.

A 36-year-old man visited Yeungnam University Hospital with a sudden onset of palpitation, headache, and was found to be hypertensive. Chest radiography showed a 6 cm sized mass lesion on the posterior mediastinum. A biochemical study showed elevated levels of catecholamines. An I-123 metaiodobenzylguanidine scan revealed a hot uptake lesion on the posterior mediastinum. The patient was prepared for surgery with ${\alpha}$ and ${\beta}$ blocking agents. Two months later, we removed the tumor successfully. A histological study proved that the resected tumor was mediastinal pheochromocytoma. Functional mediastinal pheochromocytomas are rare. Therefore, we reported the case with a literature review.

The mediastinal lipoma is an extremely rare tumor in children. Since the orininal description by Fothergill in 1781, about 120 cases have been reported in the world literature. Of these, less than 10 have been reported in children below the age of 12. We had experienced a posterior mediastinal lipoma in 3 year old boy. He did not complain of any subjective symptoms. Routine X-ray film revealed a huge round homogenous mass density in the posterior mediastinum. On posterior thoracotomy incision,bright yellow,well encapsulated, partly 1obular adipose mass was found in the posterior mediastinum. The tumor mass was removed easily,being proved to be lipoma on histopathologic examination. His postoperative course was uneventful and discharged on the 12th postoperative day.

The benign tumor of smooth muscle, the leiomyoma, may arise anywhere in the body, in such tissues as the muscularis of the gut and the media of blood vessels, although by far its most common location is the uterus. Indeed, the mediastinal leiomyomas are extremely rare, especially when one excludes those arising in the esophagus. No dogmatic statements can be made with regard to age, sex distribution, symptoms, or clinical course because of the extreme paucity of cases available for evaluation. Although the majority of the reported cases are in the posterior mediastinum, thus suggesting esophageal origin. We have experienced a right inferior mediastinal leiomyoma in 36 years old housewife. She complained hemoptysis and right lower chest pain associated with intermittent low-graded fever and chillness. Routine X-ray film revealed a large irregular cystic mass density in the right lower thoracic cavity. On exploratory thoracotomy, a huge round yellow-gray colored solid mass, measured about 2.5kg in weight, was located in the right inferior mediastinum just above right hemidiaphragm, medially. The tumor mass was removed, being proved to be leiomyoma on histopathologic examination. Her postoperative course was uneventful and discharged without complication.

Diagnosis of a thymic carcinoid was made on transthoracic fine needle aspiration in a 36-year old woman who had an anterior mediastinal mass on chest X-ray and CT scan. The aspiration smears showed numerous anastomosing ribbons and cords of small round tumor cells. The tumor cells had slightly eccentric nuclei and some granular cytoplasm. The small and uniform nuclei of the tumor cells had finely granular chromatin and thin nuclear membrane. The cytologic diagnosis of a carcinoid was confirmed on histopathologic, immunohistochemical, and electromicroscopic examination of surgical specimen.

Primary mediastinal immature teratoma is a rare germinal tumor which includes various elements of mature teratoma, choriocarcinoma, yolk sac carcinoma, embryonal carcinoma, and seminoma in some proportions. The tumor is virtually restricted to young man and the response to surgery and radiotherapy are poor. Recently, we experienced a case of primary mediastinal immature teratoma with elevated serum [-HCG and [-fetoprotein in 18 years old man. The well-encapsulated mass, weighing 4.5 kg, was completely resected and then adjuvant combination chemotherapy was tried with Vincristine, Bleomycin, and Cisplatin. Radical excision of tumor and adjuvant chemotherapy would appear to produce better result than have been reported in other cases. The postoperative course was uneventful and the tumor markers were returned to normal range.

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.

The benign teratoma is usually slow growing tumor, but we expirienced a case of primary huge mediastinal benign teratoma that had grown very rapidly, maximally during 3 years. The 14-year-old female patient was admitted to our hospital because of abnormal chest X-ray that showed 10$\times$10cm sized well definded mass with multiple calcificactions. but the mass was not present in chest X-ray perfomed on 3 years prior to admission. Under the diagnosis of teratoma, complete surgical resection was done by the left thoracotomy. The result of pathology was benign teratoma.

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.
