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.
在一只成年比格犬中发现了起源于睫状体的恶性畸胎样髓上皮瘤。前部包含分化相对良好的肿瘤细胞、软骨和神经节细胞。这些结构被解释为源自髓上皮胚胎原基的畸胎样结构。后部则高度间变且具有侵袭性。一个过渡区域含有Flexner-Wintersteiner型神经菊形团。这种肿瘤在人类和动物中都很罕见。
