Abstract

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% .
