Successful management of early recurrence after surgery for primary rib osteosarcoma in an adult.

Primary osteosarcoma is a common malignant bone tumour that principally affects the long bones, but relatively rare in flat bones, in children and adolescents. This study presents a rare case of primary rib osteosarcoma in a 59-year old man. The patient underwent second radical excision of the tumour due to a short time relapse after the first operation. Chest wall reconstruction, neoadjuvant chemotherapy before the second operation and postoperative chemotherapy were also performed. To date, 5 months have passed with no recurrence being observed.
