Periosteal osteosarcoma

Radiation-induced periosteal osteosarcoma

Radiation-induced sarcomas are a well-recognized late complication of radiation therapy. We present a rare case of a periosteal osteosarcoma of the femur developing 10 years after radiation treatment for a soft tissue sarcoma to highlight the clinical and radiological features of this rare complication of therapy and to describe its management.

Periosteal osteosarcoma: a review of clinical evidence.

Periosteal osteosarcoma (PO) is a rare primary malignant bone tumor and a variant of osteosarcoma. It is a surface lesion without evidence of medullary involvement. The radiologic appearance of periosteal osteosarcoma is a broad-based surface soft-tissue mass that causes extrinsic erosion of thickened underlying diaphyseal cortex and perpendicular periosteal reaction extending into the soft-tis...

[Periosteal osteosarcoma - personal experience with five cases].

The authors present five cases of periosteal osteosarcoma located in the femur (4) and tibia (1) in children and young adults (1 female and 4 males) with an age range of 9 - 23 years (mean age 15 years). Radiographs in all cases showed a broad-based soft tissue mass attached to the cortex with periosteal reaction and in two of them cortical disruption with extensive medullary involvement. Follo...

Periosteal Osteosarcoma Arising from the Rib and Scapula: Imaging Features in Two Cases

Periosteal osteosarcoma is an extremely rare chondroblastic osteosarcoma in the flat bone. There were authors reporting of two cases of periosteal osteosarcoma in the highly unusual sites. One of them arose from the rib, in a 17-year-old male, which appeared as a hypodense juxtacortical mass with periosteal reaction on CT. The other one arose from the scapula, in a 17-year-old female, which sho...
