title: Metastatic liposarcoma to the orbit.
abstract: OBJECTIVE
  To report a woman with blurred vision and proptosis who harbored an orbital liposarcoma that had metastasized from her abdomen.
  
  
  METHODS
  The patient underwent an orbital biopsy, followed by postoperative intravenous corticosteroids and radiation.
  
  
  RESULTS
  Pathology showed a dedifferentiated liposarcoma. The patient's visual acuity improved from 20/200 to 20/50 after treatment.
  
  
  CONCLUSIONS
  Physicians should suspect the presence of this rare orbital tumor in a person with a history of liposarcoma who has proptosis. Liposarcomas usually exhibit a higher grade of malignancy with recurrence, as shown in this patient.
