Abstract
|
|
|
|
High grade surface osteosarcoma is the most rare subtype of osteosarcoma arising on the surface of bone, accounting for less than 1% of the total number of osteosarcomas. Only a few case reports and studies have been reported in the world. In Korea, only one case out of 127 osteosarcomas has been described up to now, but there was no information about the patient, clinicopathologic features and treatment. We experienced a case of high grade surface osteosarcoma in the subtrochanteric area of a 66-year-old female and treated her with neoadjuvant chemotheraphy, wide resection and limb salvage operation with tumor prosthesis and adjuvant chemotheraphy. This tumor is identical to conventional high grade intramedullary osteosarcoma in histology, treatment and prognosis. So, this tumor should be differentiated from other surface osteosarcomas such as parosteal osteosarcoma and periosteal osteosarcoma.
