Zinc toxicosis - Associated hemolytic anemia and pancreatic disease in 2 dogs.

Two cases of canine zinc toxicosis with pancreatic disease are reported. Both dogs had pigmenturia, pallor, regenerative anemia, an inflammatory leukogram, hyperbilirubinemia, hyperamylasemia, and hyperlipasemia. Zinc toxicosis was diagnosed post-mortem in patient 1 based on the discovery of a metallic gastric foreign object, pancreatic necrosis, nephrosis, and high tissue zinc concentrations. Survey radiographs of patient 2 allowed identification and prompt removal of coins from the stomach with resolution of anemia, hyperamylasemia, and hyperlipasemia 3 days post-gastroscopy. Plasma zinc concentration was markedly elevated in patient 2. Zinc toxicosis should be considered in dogs with concurrent hemolytic anemia and pancreatic disease.
