We report a rare case of primary osteosarcoma of the rib. A 28-year-old male patient with a right anterior chest wall mass and pain was referred to our hospital. The tumor was hard, 7 ~ 8 cm in size and fixed on the 3rd to 5th rib. Radiological examination revealed the inhomogenous tumor in the chest wall, which infiltrated the surrounding tissues and destroyed the ribs. The tumor was completely resected with a sufficient surgical margin. The tumor was histologically diagnosed as osteosarcoma. Adjuvant chemotherapy (CDDP + ADM, IFM, HD-MTX) was performed. The patient is alive without recurrence 3 years after the operation.
