title: Nonteratoid Medulloepithelioma Presenting in a 78-Year-Old Male.
abstract: BACKGROUND
  Medulloepithelioma is a rare congenital neoplasm derived from precursors of the nonpigmented ciliary epithelium of the ciliary body. The average patient age at clinical presentation is 3.8 years.
  
  
  METHODS
  We present the case of a 78-year-old male with progressive lens subluxation and ocular hypertension who was found to have a ciliary body mass. After enucleation for presumed ciliary body melanoma, histopathology showed a nonteratoid medulloepithelioma. Cytogenetic analysis revealed abnormalities in chromosomes 3 and 8.
  
  
  CONCLUSIONS
  Medulloepithelioma is often initially misdiagnosed. Though congenital in nature, it can exhibit rapid growth, have chromosomal abnormalities, and must be considered in all age groups.
