Artefacts which occur during the processing of small biopsy specimens can cause sufficient tissue distortion to impair interpretation and can be a considerable source of nuisance. Triangular artefacts were noted in renal and liver biopsy specimens which were caused by foam sponges in embedding cassettes. Scanning electron microscopic examination of the sponges showed they comprised a mesh of scimitar-shaped rigid spikes which closely match the artefacts seen in the tissues.
在小活检标本处理过程中出现的假象可导致足够的组织变形，从而影响诊断，并且可能是一个相当大的麻烦来源。在肾脏和肝脏活检标本中发现了三角形假象，这些假象是由包埋盒中的泡沫海绵引起的。对海绵进行扫描电子显微镜检查发现，它们由弯刀状的刚性尖刺组成的网状结构，与在组织中看到的假象非常匹配。
