Within the term mediastinal tumors are grouped a number of cystic lesions and tumors that originate in different tissues and organs mediastinal or extramediastinales. The most common mediastinal tumors are thymomas, lymphomas, intrathoracic goiters, neurofibromas and teratomas. About a third of mediastinal tumors are asymptomatic. While the presence of symptoms is not synonymous with malignancy, there is evidence that malignant lesions are most frequently symptomatic. For malignant tumors proper extension study and an evaluation of surgical indication, which often must be preceded or followed by other therapeutic means (chemotherapy and radiotherapy) were performed.
