Costal chondrosarcoma requiring differential diagnosis from metastatic tumor.
Although chondrosarcoma is a common malignant bone tumor, cases arising in the rib are relatively rare. We experienced a case of chondrosarcoma arising in the right 10th rib during follow-up after lung cancer surgery. Although the finding of an osteolytic mass suggested a metastatic bone tumor, 18F-fluorodeoxyglucose positron-emission tomography demonstrated low fluorodeoxyglucose uptake, and a primary bone tumor was suspected. The bone tumor was resected and diagnosed as chondrosarcoma. Four years after resection, there has been no recurrence or metastasis. Positron-emission tomography was useful for differential diagnosis between a chondrosarcoma and a metastatic bone tumor.
