title: Episcleral osteocartilaginous choristoma.
abstract: OBJECTIVE
  A 31-year-old woman had a hypertropia and an episcleral choristoma in the superotemporal quadrant of the globe. The choristoma was examined.
  
  
  CONCLUSIONS
  Gross and histopathologic examination showed bone and cartilage components in the tumor, which refutes the previously accepted membranous growth pattern of episcleral osseous choristomas.
