Osteogenic sarcoma (mixed) .

  • The most common malignant tumor of osseous tissue.
  • The mean age of occurrence in the facial bones is 30-40 years. Maxilla and mandible are affected with the same proportion.
  • Clinical manifestations: Pain and swelling of the involved bone, loose teeth, paresthesia, bleeding, nasal obstruction.
  • An early radiographic finding is the widening of the periodontal ligament space.
  • There are three main types:
    • Osteolytic – no neoplastic bone formation: poorly defined (moth-eaten) radiolucency, loosening of associated teeth
    • Mixed – patches of neoplastic bone formed within a poorly defined radiolucency with variable internal radiopacity.
    • Osteosclerotic– neoplastic bone formation: Formation of sub-periosteal bone orientated at right angles to the cortex, producing the so-called ‘sun-ray appearance’, loosening of the associated teeth, distortion of the alveolar ridge.
