title: Malignant nonteratoid medulloepithelioma of the ciliary body in an adult.
abstract: BACKGROUND
  The authors describe a 62-year-old man with a malignant nonteratoid malignant medulloepithelioma of the ciliary body with extension into the anterior choroid and posterior chamber. He developed gradual loss of vision in his right eye, and a clinical diagnosis of malignant melanoma of the ciliary body and choroid was made.
  
  
  RESULTS
  Histopathologic examination of the enucleated eye showed a malignant nonteratoid medulloepithelioma of the ciliary body with extension into the anterior choroid and posterior chamber.
  
  
  CONCLUSIONS
  This report provides clinicopathologic evidence that intraocular medulloepithelioma can occur rarely in an adult. The lesion clinically may mimic a malignant melanoma. The authors also summarize five previously reported cases of this unusual lesion.
