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.

Extraskeletal osteosarcoma (ESOS) is a malignant soft tissue neoplasm producing osteoid, without any continuity with the bone or periosteum. Primary ESOS presenting in the mediastinum is an extremely rare, yet aggressive malignant tumor associated with a poor prognosis. We report a case of primary ESOS arising from the thymus in a 63-year-old male patient.

Mediastinal ganglioneuroma is infrequently encountered in childhood. The posterior mediastinal ganglioneuroma which extended the contralateral thorax was very rare. A 4-year-old boy had a ganglioneuroma which involved bilateral thorax and encased the aorta and azygous vein and the ganglioneuroma was successfully extirpated by two-staged operations.; left thoracotomy first right thoracotomy 10days later.

The recurrence of an anterior mediastinal mass was discovered incidentally on the chest film for an asymptomatic 72-year-old female. She underwent the mass resection at the same site in 1989 and was diagnosed as a paraganglioma of the anterior mediastinum. She had poorly controlled hypertension which was converted into normal blood pressure after the first operation. During the follow up, the catecholamine levels were within normal limits, and there were no evidence of recurrence of the tumor. However, 6.3 years later, the mass recurred at the same anterior mediastinum. The patient had no hypertension and catecholamine levels were still within normal limits. The recurring mass was successfully removed and had the same histological findings - recurring paraganglioma.

Lipoma is a circumscribed mesenchymal tumor originating from the adipose tissue. The lesion is usually small and asymptomatic. The most common location is in the neck region, however, lipoma can be found in the mediastinum in rare occasions. Although lipoma reach to the large proportions in the mediastinum, it rarely compresses the neurovascular structure. We present a case of a 58-year-old man, in which a hourglass-type cervicomediastinal lipoma produced Horner's syndrome with voice change. The man presented a swelling at the right side of his neck, ptosis and anhidrosis on the right side of his face, and right chest discomfort. After the removal of the mass, all the symptoms which had been provoked by compression, as well as Horner's syndrome and hoarseness, nearly disappeared.

An occurrence of hemangioma in the mediastinum is a very rare, accounting for less than 0.5% of mediastinal tumors. Capillary hemangiomas and cavernous hemangiomas consists of over 90% of mediastinal hemangiomas. However, venous hemangioma has never been reported in South Korea and has also very rarely been reported worldwide. We found mediastinal solid mass, as an incidental finding during a follow-up chest CT scan of a 44-year-old female patient who had undergone colon cancer surgery. We performed a mediastinoscopic biopsy. We did a thoracotomy to remove this mass because hemorrhage and found a totally resected venous hemangioma.

Desmoplastic small round cell tumor (DSRCT) is rare and a recently described, poorly differentiated malignant tumor and it usually presents with widespread intra-abdominal involvement. We report a case of DSRCT arising form the mediastinum which was treated with multimodality anticancer therapy in 15 year-old girl.

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.

Cavernous hemangioma in mediastinum is a rare tumor. A 13 year old girl was referred becaused of abnormal mediastinal shadow in simple chest X-ray. Chest CT scan revealed a somewhat inhomogenous cystic legion arround the whole length of SVC. Surgical excision was done through the right posterolateral thorachotomy. The pathology was confirmed as cavernous hemangioma.

A 45 year old man was admitted for further examination of an abnormal shadow of the right posterior mediastinum. The patient suffered from dysesthesia in the right thoracic wall of dermatome T7. CT scan and MRI revealed that two separate tumors had developed in the right paravertebral area linked to the vertebral canal via an intervertebral foramina. One-stage removal of the tumors were performed safely through the right posterolateral thoracotomy following the resection of the rib head and vertebral pedicle. The tumors were confirmed as histologically neurilemomas. The postoperative course was uneventful.
