Abstract

 


Mediastinal dedifferentiated chondrosarcoma is fairly rare and defined as a high-grade sarcoma occuring on chondrosarcoma. A patient with mediastinal dedifferentiated chondrosarcoma had been treated with orchiectomy and chemotherapy for testicular mixed germ cell tumor four years ago underwent left pneumonectomy and total tumor excision. He developed local recurrence and distant metastasis after one month following operation. Dedifferentiated chondrosarcoma is resistant to radiation therapy and chemotherapy. The only chance of cure is total wide resection but this is also generally unsuccessful. [Journal of Turgut Ozal Medical Center 1997;4(1):112-115]
