[Chondrosarcoma of the chest wall]

We report 2 patients with chondrosarcoma of the chest wall. They were a 67-year-old woman (case 1) with an anterior chest wall tumor and a 68-year-old woman (case 2) with a painful rib tumor. Their computed tomography (CT) both revealed calcified tumors. Case 1 underwent a wide resection by partial sternectomy, with free surgical margins. Case 2 underwent tumor resection with the posterior part of the 3rd rib, with positive surgical margin in the vertebral site, and received adjuvant radiotherapy. Both patients were pathologically diagnosed as having grade II chondrosarcoma. In their postoperative courses, they are free from recurrence. Wide resection is likely to be the key to successful management of chest wall chondrosarcoma.
