Diagnostic proposé









Ostéosarcome périostéal


Proposed diagnosis









Periosteal osteosarcoma



Tumeur diaphysaire, périostée, à extension en surface du fémur (La plupart des cas rapportés sont localisés au niveau du tibia ou du fémur)

La lésion semble être limitée à la corticale.

Prolifération productrice d'ostéoïde avec large composante chondroïde (parentée avec le chondrosarcome périostéal)



Tumor grows on the surface of the femur(or other long bone: Most of the reported cases have been located in the upper tibial shaft or femur )

Lesion is limited to the cortex (and only rarely invade the medullary cavity)

Osteoid forming lesion with a prominent cartilaginous component (Tumour closely related to juxtacortical or periosteal chondrosarcoma)

Purpose: Periosteal osteosarcomas are rare cartilage-rich bone tumours characterized by a juxtacortical eccentric position and are normally regarded oncologically as of intermediate to high grade.Their low incidence is mirrored by a small number of reported cases in the world literature. While there is general agreement that wide surgical excision is required, there is a paucity of evidence regarding adjuvant therapy. Previous reports have not indicated any consistent approach to this to allow appraisal.Patients and methods: We report 17 cases treated at our centre over 16 years. Our policy was to use chemotherapy when the tumour showed any features of high grade.Results: To date, no deaths have resulted from recurrence or metastasis of the tumour although there have been two deaths from other causes.Discussion: Comparison of survival with existing studies is made to draw conclusions regarding future treatment of this condition in terms of surgical and adjuvant approaches.

Periosteal osteosarcoma: long-term outcome and risk of late recurrence.

The long-term outcome of periosteal osteosarcoma is not well defined. We sought to examine the disease-specific survival and risk of late recurrence or dedifferentiation in a cohort of 29 patients with average of 15.8 years followup. Disease-free survival was 83%, with five patients dying of disease at an average of 26 months after presentation. Survival was similar with respect to anatomic location, pathologic grade, and limb-salvage resection. All instances of local recurrence, metastatic disease, and death occurred within 3 years after presentation. There were no instances of dedifferentiation. Long-term disease-free survival is possible after resection of the local recurrence. Limb-salvage therapy seems to offer survival equivalent to amputation, and there does not seem to be a substantial risk of late recurrence, dedifferentiation, or disease progression.
