The fine structure of a surgically excised colloid cyst is described. The cyst was lined by ciliated and nonciliated columnar cells. The nonciliated cells contained secretory material and had a surface coating. In addition, a third type of smaller cell was seen wedged between the columnar cells and abutting on the basement membrane. These cells contained abundant free ribosomes and tonofilaments and displayed well developed desmosomes and half desmosomes. The cyst lining closely resembled the upper respiratory epithelium rather than neuroepithelium, thus supporting the contention that colloid cysts are derived from an endodermal source.
本文描述了手术切除的胶样囊肿的精细结构。囊肿内衬有纤毛和无纤毛的柱状细胞。无纤毛细胞含有分泌物质并具有表面涂层。此外，还可见到第三种较小的细胞，楔入柱状细胞之间并紧贴基底膜。这些细胞含有丰富的游离核糖体和张力丝，并显示出发育良好的桥粒和半桥粒。囊肿内衬与上呼吸道上皮而非神经上皮非常相似，因此支持胶样囊肿来源于内胚层的观点。
