Giant Cell Tumor of the Rib；Report of a Case

骨巨細胞腫の多くは四肢長管骨に発生し，肋骨原発はまれとされている．われわれは肋骨原発の骨巨細胞腫の1例を経験したので報告する．

We report a rare case of giant cell tumor of the rib. A 33-year-old man was admitted to our hospital because of a recently appearing mass and pain in the right chest wall. Chest computed tomography and magnetic resonance imaging revealed a heterogeneous mass of 8-cm in diameter arising from and destroying the right 7th rib. The tumor was resected together with the 6th, 7th, and 8th ribs and the adjacent muscle and diaphragm. The pathological diagnosis was giant cell tumor of the bone. The patient has been free from recurrence or metastasis for 4 years after the operation.
