肺活检标本间质内有致密红染无结构样物时应首先考虑淀粉样物沉积症(amyloidosis)。如果刚果红染色没有显示特征性的双折射性“苹果绿”时,往往考虑是由于技术不当所致的染色欠佳。在缺少电镜的情况下,这些病例通常被推测性的诊断为淀粉样物沉积症。而轻链沉积病(lightchain de
Lung biopsy specimens interstitial dense dense red dye without structural samples should be the first to consider amyloidosis (amyloidosis). If Congo Red staining does not show the characteristic birefringence “apple green”, it is often the case that poor staining due to improper technology is considered. In the absence of electron microscopy, these cases are often speculatively diagnosed as amyloidosis. The light chain deposition disease (lightchain de
