title: [Radiation induced osteosarcoma of the chest wall].
abstract: We report a successful resection of an osteosarcoma in the chest wall developed 25 years after irradiation. A 74-year-old woman was admitted to our hospital for her swelling in the left chest wall at August 24, 1995. At 49-year-old, she had undergone an operation and postoperative irradiation for left breast cancer. A computed tomography demonstrated a mass in the left chest wall that destructed the first rib, extending into the pleural space and invaded into the left common carotid and subclavian arteries. We planned a radical resection of the mass after repeated CT scannings, since it was histopathologically diagnosed as a chondrosarcoma and showed a rapid growth. The tumor was completely removed with radical transmediastinal forequarter amputation of the partial chest wall and total left upper extremity. The left common carotid artery was partially replaced with 6 mm EPTFE vascular prosthesis. The chest wall was reconstructed with Marlex-mesh prosthesis and a myocutaneous flap. She was discharged uneventfully and has not shown any evidence of recurrence.
