Renal amyloidosis in a Shar-Pei dog: A case report

The clinical and pathological findings of a case of renal amyloidosis in a nine-year-old male Shar-Pei dog were described. Clinically, there were signs of sporotrichosis and renal insufficiency, besides being positive to leishmaniasis and ehrlichiosis. On the day before death, the animal became apathetic, dehydrated and anuric. On gross examination, there were several whitish millimetric spots seen widespread in both renal cortices and consolidation of the left diaphragmatic pulmonary lobe. The most important microscopic finding was a deposition of amorphous acellular material on the glomerular tufts which stained positively by congo red stain. Other changes were multifocal suppurative nephritis, thickening of the Bowman capsule and chronic suppurative bronchopneumonia. The origin of the amyloidosis in this case could be hereditary, being similar to familiar amyloidosis described in Shar-Pei breed, or due to chronic suppurative inflammation and/or leishmaniasis.
