title: Mediastinal mass following chemotherapy in patients with Ewing sarcoma and osteosarcoma.
abstract: Thymic hyperplasia following combination chemotherapy for malignant disease is very uncommon in adolescents and adults. Our experience includes a thymic enlargement noted on the sequential computed tomography (CT) in three patients who were disease-free after chemotherapy for Ewing sarcoma (2) and osteosarcoma (1). The development of an anterior mediastinal mass after successful chemotherapy does not always imply relapse of malignant disease. To prevent inappropriate treatment, the possibility of benign aetiology must be considered.
