title: [Costal chondrosarcoma. 4 cases].
abstract: BACKGROUND
  Tumors of the rib cage are uncommon and malignant in 29% of the cases. Chondrosarcoma predominates, accounting for 40% of all cases of malignant costal tumors.
  
  
  METHODS
  Four patients (3 women, 1 man, mean age 28.2 years) were hospitalized for costal chondrosarcoma. Pain and tumefaction dominated the clinical presentation. Calcifications suggested the diagnosis in 3 cases. Curative surgery was performed in all cases. Postoperative radiotherapy was unable to improve prognosis in 2 patients.
  
  
  CONCLUSIONS
  Chondrosarcoma of the ribs is characterized by a strong potential for invasive extension. Diagnosis is suspected on the basis of imaging findings and confirmed at pathology. Surgery is required. Chemotherapy and radiotherapy do not improve prognosis significantly.
