Abstract

The right eye of a 1-year-old black infant with a painful blind eye was studied histologically. It contained a tumor at an advanced stage of growth. The tumor consisted of moderately large, round, and elongated undifferentiated cells and anaplastic cells with mitotic figures combined with multilayered, poorly differentiated epithelial cells that resembled the medullary epithelium of embryonic retina. Strap cells with cross striation typical of striated muscle were also present, together with islands of hyaline cartilage and areas of calcification.

摘要

对一名1岁患有疼痛性盲眼的黑人婴儿的右眼进行了组织学研究。眼中有一个处于生长晚期的肿瘤。肿瘤由中等大小的圆形和细长形未分化细胞以及有丝分裂象的间变细胞组成，还伴有多层低分化上皮细胞，类似于胚胎视网膜的髓样上皮。还存在具有横纹肌典型横纹的带状细胞，以及透明软骨岛和钙化区域。
