[Osteomyelitis and papillary renal adenoma in a red panda (Ailurus fulgens fulgens)]

A 13 year-old female Red Panda (Ailurus fulgens fulgens) kept in a zoological garden was euthanatized due to poor general condition. Pathological examination revealed a chronic bacterial ulcerative to necrotizing dermatitis and osteomyelitis at the lower jaw with subsequent pyogranulomatous pneumonia and diffuse hydropic degeneration of the liver. Additionally, in the kidney a papillary renal adenoma was found. Immunohistochemistry revealed an expression of cytokeratins 8 and/or 19 indicating an origin from the renal tubular epithelium.
