title: Osteogenic sarcoma and phthisis bulbi: a case report.
abstract: OBJECTIVE
  To describe a case of osteogenic sarcoma (osteosarcoma) that developed within a phthisical eye.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  An 86-year-old woman with a 20-year history of phthisis bulbi developed pain and proptosis. Tumor was identified by computed tomography. An exenteration was performed, and osteogenic sarcoma was identified.
  
  
  CONCLUSIONS
  Osteogenic sarcoma is the most common primary malignant tumor of bone. In the orbit it frequently is associated with prior irradiation for retinoblastoma. We describe the first case of osteogenic sarcoma that developed de novo from bone within a phthisical eye.
