Bone tumors

Periosteal osteosarcoma

BoneMalignant / sarcomaOsteogenic tumours

Epidemiology

An intermediate-grade surface osteosarcoma, most common in adolescents and young adults. Because it arises on the diaphyseal surface, MRI defines how much it invades the marrow and soft tissues before deciding on surgery.

Basic features

It arises from the cortical surface and often has a chondroid matrix, with pain or a mass in the shaft of long bones.

Usual treatment

The mainstay is wide resection; chemotherapy is individualized according to grade, extent within the marrow, and the tumor board.

Outcomes and prognosis

Its behavior is intermediate between parosteal and conventional osteosarcoma, with a generally favorable prognosis; follow-up must look for recurrence and metastasis.

Warning signs

These signs do not necessarily mean cancer, but they warrant evaluation before operating on or needling a mass.

  • A soft-tissue mass that grows, is larger than 5 cm, or is deep.
  • Persistent, night-time or progressive bone pain, especially if it limits activity.
  • A fracture from minimal trauma, or an aggressive bone lesion on an X-ray.
  • A lump that comes back after previous surgery.
  • Neurological symptoms, rapid swelling, or pain associated with a mass.

This information is general and does not replace a medical evaluation. A musculoskeletal tumor must be interpreted together with imaging, physical examination, biopsy when appropriate and each patient's context.

Specialist evaluation

If you have a mass, a bone lesion or a report suggesting a tumor, book an evaluation.
