Abstract
|
|
|
|
An extraskeletal osteosarcoma is a rare malignancy. A small number of cases and studies have been reported in the world and only two cases have been reported in Korea. We experienced an extraskeletal osteosarcoma around the knee joint of 91-year-old male who was the oldest case in the literatures. It was developed without history of trauma, irradiation, myositis ossificans, and heterotopic ossification of dermatomyositis. This patient was treated with excision alone, however he was alive and there were no sign of local recurrence or distant metastasis and functional loss during 1-year follow-up.
