A malignant teratoid medulloepithelioma that arose from the ciliary body was found in an adult Beagle. The anterior part contained relatively well-differentiated tumor cells, cartilage, and ganglion cells. These structures were interpreted as teratoid formations derived from the embryonic anlage of the medullary epithelium. The more posterior part was highly anaplastic and invasive. A transitional area contained neural rosettes of the Flexner-Wintersteiner type. This tumor is rare in both man and animals.
