title: [Classification and pathology of mediastinal tumors].
abstract: The mediastinum is a longitudinal septum between the right and left pleural cavities which contains various organs and tissues. A variety of tumor and tumor-like lesions develop in this region. There have been various disputes in the past regarding the histogenesis of thymomas, thymic carcinoids, germ cell tumors, and lymphocytic tumors, and these tumors and their associated disorders, including myasthenia gravis, have attracted the interest of surgeons, physicians, radiologists and pathologists. A general description of the classification and pathology of these interesting tumors has been given as an introduction to this special edition, "Diagnostics and Therapy of Mediastinal Tumors".
