Growing mediastinal metastatic tumour in a patient with burned out testicular cancer.

A 27-year-old man was referred to us for resection of a post-chemotherapy growing mass in the mediastinum. He had been treated with 4 courses of combination chemotherapy for his testicular cancer. The primary lesion was burned out and the anterior mediastinal metastatic tumour contained immature teratoma. After normalization of tumour marker levels, the mediastinal mass was resected completely and the resected specimen showed teratoma with rhabdomyosarcoma. Two rare clinical conditions have been seen in this case.
