Renal amyloidosis was diagnosed in 14 young Chinese Shar Pei dogs, all of which were related. Clinical signs were those of renal failure and included vomiting, anorexia, lethargy, polydipsia, polyuria, weight loss, and dehydration. Some dogs had a history of intermittent fever and joint swelling. Laboratory findings also were compatible with renal failure and included azotemia, hyperphosphatemia, low total CO2 content in serum, isosthenuria, proteinuria, and hypercholesterolemia. All dogs had medullary deposition of amyloid, and 9 of 14 (64%) had glomerular involvement. The remaining renal lesions were typical of end-stage renal disease. In some dogs, amyloid deposits were found in other tissues (eg, liver, spleen, stomach, small intestine, myocardium, lymph node, prostate gland, thyroid gland, and pancreas). Amyloid deposits were sensitive to potassium permanganate oxidation, suggesting the presence of amyloid protein AA.

A 3-year-old, spayed female, Domestic Shorthair cat presented with anorexia, lethargy, vomiting, probable hemoabdomen, and multiple masses on the right lateral liver lobe. Clinicopathologic and imaging abnormalities included anemia, azotemia, icterus, and hepatomegaly with hypoechoic masses. On cytologic evaluation of a fine-needle aspiration of a liver mass there was abundant extracellular pink- to purple-colored material between hepatocytes. The amorphous material was stained with direct fast scarlet (DFS), and green birefringent areas were observed under polarized light, confirming the presence of amyloid. A unique finding on the cytologic smear were macrophages containing amorphous and fibrillar amyloid-like protein. Histopathologic examination using H&E and Congo red staining confirmed amyloid deposits within the space of Disse, along the sinusoids, portal tracts, blood vessel walls, and within the cytoplasm of macrophages. Immunohistochemical staining with anti-AA amyloid antibodies further confirmed the presence of AA amyloid. To the author's knowledge, this is the first report of the cytologic finding of AA amyloid protein within macrophages and DFS stain detection of amyloid on a cytologic smear.
