  • 17% of primary malignant bone tumours
  • Sites:
    1. Pelvis 30%
    2. Femur 20%
    3. Femoral head 10%
    4. Ribs 10%

Presentation

  • Most common malignant tumour of the hands and face in middle aged patients
  • Usually occurs in the metaphysis or diaphysis
  • Presents with constant ache or increased size of a pre-existing lump
