We experienced a rare case of dedifferentiated chondrosarcoma of the rib, which was widely resected with chest wall reconstruction. A 44-year-old man complaining of an anterior chest mass with pain was referred to the hospital with a diagnosis of chondrosarcoma. Resections of the 5th, 6th and 7th ribs and an extraction of the tumor were performed. Because the direct infiltration of the tumor extended to the lingula of the lung, diaphragm and pericardia, the mass was removed en bloc. The 16×15cm defect of chest wall was fixed by sutures with silk threads and a chest wall reconstruction was performed using Marlex mesh. The extirpated tumor was measured 12×8×11cm and diagnosed as dedifferentiated chondrosarcoma. Histologically, the tumor consisted of chondrosarcomatous component juxtaposed to fibrosarcomatous component. Postoperatively, the pulmonary function, and mobility of the upper extremities were not reduced. But he died of local recurrence 5 months after the operation.
