Primary chondromyxoid fibroma is a benign bone tumor. Its localization in the sternum is quite rare; we found only 6 relevant reports. We report our diagnosis and treatment of a chondromyxoid fibroma in the sternum of a 63-year-old woman. The patient underwent subtotal sternectomy and chest-wall reconstruction with use of a titanium rib bridge system and Prolene mesh. The patient's clinical course was uneventful, and she had no local recurrence 41 months postoperatively. Our review herein of the 6 previous cases reveals that our patient is the oldest thus far to have been diagnosed with a sternal chondromyxoid fibroma.
