RESUMEN
Cholangiocarcinomas are neoplasms originating from the biliary epithelium. This report describes the gross, microscopic, and immunohistochemical findings in a case of cholangiocarcinoma in an Australian goose (Cereopsisnovaehollandiae). The animal had cachexia and ascites. The liver and gallbladder had cystic masses that was diagnosed as acholangiocarcinoma.(AU)

Squamous cell carcinoma (SCC) is a common oral neoplasm in domestic cats, but there are only a few reports in wild felids. A captive 10-years-old, female Siberian tiger (Panthera tigris altaica), with history of chronic renal disease and serologically positive for Leishmania sp. developed a lytic mandibular nodule that was histologically diagnosed as SCC. At necropsy was also observed an exocrine pancreatic carcinoma, which was considered an incidental finding, and a chronic lympho-plasmocytic interstitial nephritis associated with a membranous glomerulopathy, compatible with the chronic renal disease presented by the animal. To the best of our knowledge this is the first report of an invasive and non-metastatic mandibular SCC in a Siberian tiger.

Reported cases of neoplasia affecting hippopotamus are very scarce. This report describes a metastatic oral squamous cell carcinoma in a captive 44-year-old male common hippopotamus (Hippopotamus amphibius) that developed progressive loss of appetite, fibrinohemorrhagic oral discharge, and progressive weight loss. Gross, cytological, and histopathological findings were compatible with a conclusive diagnosis of an invasive oral squamous cell carcinoma with metastasis in the lung, adrenal, and spleen. To the best of our knowledge this is the first report of squamous cell carcinoma in a common hippopotamus.
