title: Primary orbital angiosarcoma: a case report.
abstract: OBJECTIVE
  The pathogenesis, natural history, histopathology, and recommended treatment for orbital angiosarcoma are illustrated and reviewed.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  A 71-year-old white male presented with bluish discoloration and swelling of the left medial canthal area. A fine needle aspiration and excisional biopsy with histopathologic examination was performed, which showed angiosarcoma. Pattern of growth was demonstrated radiographically and histopathologically, confirming primary orbital angiosarcoma. Subsequent wide surgical resection was carried out, with substantial reconstruction of the left orbital and periorbital area. The patient responded well to the surgery, and was free of tumor after six years of follow-up.
  
  
  CONCLUSIONS
  Angiosarcoma is a rare and highly malignant tumor of epithelial origin. The aggressive nature of this tumor usually results in a high mortality rate despite treatment. However, early diagnosis and wide surgical excision has resulted in successful treatment of these tumors.
