title: Posterior scleral choristoma in the organoid nevus syndrome (linear nevus sebaceus of Jadassohn).
abstract: OBJECTIVE
  To highlight the association of posterior osseous and/or cartilaginous ocular choristomas with epibulbar choristomas and the nevus sebaceus of Jadassohn.
  
  
  METHODS
  Small case series.
  
  
  METHODS
  Four patients with the organoid nevus syndrome.
  
  
  METHODS
  Clinical and histopathologic studies in four patients with epibulbar lesions and nevus sebaceus of Jadassohn.
  
  
  METHODS
  Ophthalmoscopic findings of peripapillary lesions. Computed tomographic and ultrasonographic characteristic of posterior scleral lesions. Ocular histopathologic findings in one globe from one of the study subjects.
  
  
  RESULTS
  Three patients had the triad of posterior osseous/cartilaginous ocular choristomas, anterior epibulbar choristomas, and nevus sebaceus of Jadassohn and one patient had anterior epibulbar choristomas and posterior osseous/cartilaginous ocular choristomas. Ultrasonography and computed tomography were valuable in detecting scleral ossification or epibulbar cartilage or both. The ophthalmoscopic findings were similar to those of a choroidal osteoma.
  
  
  CONCLUSIONS
  The presence of posterior osseous/cartilaginous ocular choristomas in a patient with epilepsy or epibulbar lesions or both suggests the diagnosis of nevus sebaceus of Jadassohn. Osseous/cartilaginous ocular choristomas should be suspected in patients with nevus sebaceus of Jadassohn and peripapillary hypopigmented fundus lesions.
