title: [Mediastinal tumors: introduction].
abstract: Mediastinal tumors are relatively uncommon, usually incidentally discovered on a chest X-ray in asymptomatic patients. Young adults are particularly concerned. Mediastinal masses represent a group of heterogeneous histological type cell. A definite diagnosis is essential leading to an adequate prompt therapeutic strategy when either benign disease or aggressive malignant tumor is conceivable. Indeed the therapeutic management of such tumors could be strictly medical, requiring exclusive surgical approach or includes a multimodal treatment. Clinical examination and imaging are important tools in the diagnostic approach. However the specific diagnosis could be complex and requires histological confirmation by an experienced pathologist after examination of large biopsies of the tumor. Several investigations, including surgical invasive exploration, should be quickly requested in order to achieve a final diagnosis and refer patients in an adequate therapeutic scheme without delay. The aim of this article is to point out the available diagnostic tools in mediastinal masses, including surgical approach, and to identify the role of surgical resection in specific subtypes.
