Diktyoma

Diktyoma
Histopathology of medulloepithelioma showing characteristic neural tube like strands.

Diktyoma, or ciliary body medulloepithelioma, or teratoneuroma, is a rare tumor arising from primitive medullary epithelium in the ciliary body of the eye. Almost all diktyomas arise in the ciliary body, although, rarely, they may arise from the optic nerve head or retina.[1]

The name "diktyoma" comes from its characteristic findings on histology.
