Medulloepithelioma of the ciliary body

Neuroepithelial tumors of the ciliary body occur more seldom than retinoblastoma. The congenital form is called medulloepithelioma, the adult-acquired adenoma or adenocarcinoma. Medulloepitheliomas consist of organoid epithelial structures developing anteriorly along surfaces such as the iris. The authors report on a congenital type unusually growing not only anteriorly along the lens, but also posteriorly along the retina's surface causing retinal detachment.
