Hyaline or colloid bodies (Civatte bodies) and amyloid are sometimes confused because of their similar appearance under the light microscope. A differentiation can be made by histochemical means (DMAB-Nitrite method) and by fluorescence or polarization microscopy. At the ultrastructural level hyaline or colloid bodies as well as amyloid exhibit a fibrillar structure, but can be differentiated by the diameter and arrangement of fibrils and the localization of the aggregations. A clearcut differentiation between hyaline or colloid bodies and amyloid seems of great importance in any dicussion of the epidermal origin of amyloid and the classification of fibrillar aggregations associated with skin tumours.
透明小体或胶样小体（西瓦特小体）与淀粉样蛋白有时会因在光学显微镜下外观相似而被混淆。可通过组织化学方法（二甲基氨基联苯胺-亚硝酸盐法）以及荧光或偏振显微镜进行区分。在超微结构层面，透明小体或胶样小体以及淀粉样蛋白均呈现出纤维状结构，但可通过纤维的直径和排列方式以及聚集体的定位进行区分。在任何关于淀粉样蛋白的表皮起源以及与皮肤肿瘤相关的纤维状聚集体分类的讨论中，明确区分透明小体或胶样小体与淀粉样蛋白似乎都非常重要。
