title: Orbital metastasis: a rare manifestation of scapular bone osteosarcoma.
abstract: OBJECTIVE
  To report a case of orbital metastasis from scapular bone osteosarcoma.
  
  
  METHODS
  A 55-year-old man who was a known case of scapular bone osteosarcoma, was referred to our clinic with ocular symptoms including acute painful decreased vision, proptosis, conjunctival injection, and chemosis. He had undergone surgical excision of the original tumor and received systemic chemotherapy 4 months before. Imaging studies and incisional biopsy were performed for the orbital lesion, the histopathological examination confirmed the diagnosis of metastatic osteosarcoma. The patient was referred to the oncologist for palliative chemotherapy and further intervention; however, he deceased 2 months later due to sepsis in the context of immunosuppression.
  
  
  CONCLUSIONS
  Metastatic involvement of the orbit due to osteosarcoma is a rare condition manifesting with orbital mass, pain, diplopia and ocular motility disturbance. Although there is no effective treatment, the combination of modalities such as chemotherapy, radiotherapy, and surgery may delay progression of the disease.
