Mediastinal chondroma is a benign mesenchymal neoplasm composed of hyaline cartilage arising as an extraosseal mass in mediastinum. Primary chondromas arising in mediastinum most probably develop from embryonal pluripotent cells or through connective tissue metaplasia, as suggested by Macchiarini and Ostertag in 2004.

Clinical Features

  • Incidence

    True primary mediastinal extraosseous chondromas are extremely rare.

  • Age

    There are no data about primary mediastinal chondromas, but soft-tissue chondromas in general occur in middle-aged patients and are rare in children.

  • Sex

    There are no data specific for primary mediastinal chondromas, but soft-tissue chondromas are more common in men than women (3:2).

  • Site

    Most common in anterior mediastinum but can also appear in posterior mediastinum.

  • Treatment

    Although histologically they are benign lesions, they tend to have malignant clinical course, and local...
