A case of primary amyloidosis, initially detected by fine-needle aspiration of the liver, is reported here. Amorphous acellular metachromatic material was seen extracellularly in between the hepatocytic cords compressing them. This material showed typical apple-green birefringence under crossed bipolars after alkaline Congo-red staining proved its amyloid nature. It was resistant to potassium permanganate pretreatment, indicating it to be of the AL type.
本文报道了一例原发性淀粉样变性病例，最初通过肝脏细针穿刺活检发现。在肝索之间的细胞外可见无定形、无细胞的异染性物质，压迫肝索。碱性刚果红染色后，该物质在交叉偏振光下呈现典型的苹果绿双折射，证实其淀粉样变性的性质。它对高锰酸钾预处理有抗性，表明其为AL型。
