Abstract
We reported a case of fibrous dysplasia of the left sixth rib in a 31-year-old man . In this case, the disease was detected from an abnormal shadow on a plain X-ray film at medical check-up.rChest CT suggested tumor of the rib bone. We observed that the lesion was localized in the sixth rib without pleural invasion by video monitoring through a thoracoscope. Total extirpation of the left sixth rib was performed under an axillar skin incision with the thoracoscope. The pathological diagnosis was fibrous dysplasia. Video-assisted thoracoscopic surgery is useful for detection of the extension and pleural invasion of the rib tumors.
