They may also occur as a result of local extension of adjacent compartment organ growth into the neighboring space or as a result of the arrest of embryonic cells traversing this compartment with later tumor growth. Uncommon primary mediastinal tumors usually are of mesenchymal origin. These tumors represent fewer than 10% of primary mediastinal tumors and have a higher prevalence and malignant potential in children.1
