Osteogenic sarcoma (mixed)

Osteogenic sarcoma (mixed)

  • Primary malignant tumor of bone. The most common malignancy of bone tissue.
  • Peak age of occurrence in the facial bones is 20-40 years old.
  • Oral manifestations: Pain and swelling of the involved bone, loose teeth, paresthesia, bleeding, nasal obstruction.
  • An early manifestation is the widening of the periadontal 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: poorly defined radiolucent area with variable internal radiopacity.
    • Osteosclerotic- neoplastic bone formation: often formation of sub-periosteal bone orientated at right angles to the original cortex, producing the so-called sun-ray appearance, loosening of associated teeth, distortion of the alveolar ridge.
