Nonteratoid Medulloepithelioma Presenting in a 78-Year-Old Male

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. Case Presentation: 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. Conclusion: 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.
