We have experienced 27 cases of primary medistinal tumors and cyst from April, 1986 to April 1996. At Masan Samsung General Hospital. The results of the anslysed were as follows 1. Of 27 medistinal tumors and c,pests, 9 patients were male and 18 patients were female(m : f= 1 : 2) 2. The most common chief complaint was chest discomfort or pain(8 cases 30 %) and 17 patients(63%) were asymptomatic. 3. The most common primary medistinal tumor was Neurogenic tumor in 9 cases(33 %) followed by Thymoma in 7 cases(26 %), teratoma in 6 cases(22 %) 4. The incidence of malignancy of all case was 3 cases(11 %), all cases were symptomatic and the most common malignancy was malig. thymoma(3 cases,43 %) 5. The anterior mediastinum was the most common tumor location with 15 cases(56 %) followed by posterior 11(41 %) and middle mediastinum 1(4 %). Anterior mediastinum tumors were predominantly thymomas and teratoma and posterior mediastinal tumors were neurogenic tumors 6. Complete removal of tumor was achieved in 26 cases(96 %) and open biopsy was done on 1 case 7. Postoperative complications were continued lumbar shunt drainage in 1 case and wound infection in 1 case 8. There was no case of postoperative mortality and good clinical course in surgically completely rejected cases

Mediastinal teratoma is a tumor that thoracic surgeons made an operation much less commonly than other mediastinal masses and most of them are asymptomatic. But very rarely, this tumor invades the pleura and pericardium resulting in pleural effusion, pericardial effusion and cardiac tamponade in severe cases. The mechanism of invasion and perforation of the tumor is unknown and tumor-consisting tissue factor is suspected of a cause. In this case, we operated on a patient whose anterior mediastinal teratoma invaded and perforated pericardium and pleura resulting in pericardial effusion and pleural effusion. The patient was improved and discharged with no problem after resection of mass and involved pericardium.

Multiple symmetric lipomatosis is a rare disease characterized by progressive growth of subcutaneous fat masses which are located symmetrically at neck, shoulders, chest, abdomen and groin. Recent surveys revealed a high incidence of combined somatic and autonomic neuropathy. The exact cause of the disease is not known. We have experienced one case of multiple symmetric lipomatosis with mediastinal involvement with symptomatic compression of trachea. The patient was a 55-year-male, complaining of dyspnea and slowly enlarging multiple symmetric masses at the neck, shoulders, chest, abdomen, flank and groin over a period of 10 years. He had a habit of excessive alcohol intake for many years. The fatty masses in the neck and the upper mediastinum including peritracheal region were excised through transverse cervical incision. But, because of the incomplete excision of peritracheal fatty tissue, we performed reoperation for the relief of residual tracheal compression at the 15th postoperative day. Two days later emergent tracheostomy was performed due to postoperative pneumomediastinum and subcutaneous emphysema. He could discharge with permanant tracheostomy.
