Abstract
A rare case of a parosteal osteosarcoma of the rib was reported. A 40-year-old woman visited our hospital in July 1983 because of a painful tumor. The tumor was solid and localized in the middle segment of the left 7th rib. A simple resection of the tumor was performed and the diagnosis was osteochondroma. In August 1987, tumor recurred at the same region of the left chest.
A diagnosis of parosteal osteosarcoma was made after an excisional biopsy and a wide resection was additionally performed with excision of the left 6 and 7th ribs. The defect of the chest wall was repaired with dacron sheet.
The patient was well alive 15 months without any sign of recurrence.
