Epidemiology

A low-grade malignant tumor that typically affects the tibia (shinbone) in adolescents and young adults. A location in the front of the tibia in a young patient is a strong clue and requires distinguishing it from osteofibrous dysplasia.

Basic features

It can cause chronic pain, deformity, or swelling at the front of the leg, often with a long-standing history.

Usual treatment

The decisive treatment is wide resection with reconstruction (avoiding curettage, which increases recurrence), because it does not respond reliably to chemotherapy or radiotherapy.

Outcomes and prognosis

It is low-grade malignant: the prognosis is favorable with wide resection, but it can recur or metastasize late, so it requires long-term surveillance.

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.
