Asian palm civets (Paradoxurus hermaphroditus), or toddy cats, belong to the family Viverridae. Little is known about the pathology of these animals and few articles have been published, mainly concerning their important role as wild reservoir hosts for severe infectious diseases of domestic animals and human beings. A 4-year-old, female Asian palm civet was found dead by the owner. At necropsy, large amount of adipose tissue was found in the subcutis and in the peritoneal cavity. Most of the pancreas appeared red, translucent. Hepatomegaly, discoloration of the liver were evident, with multifocal areas of degeneration, characterized by white nodular lesions. Histologically, the pancreas showed severe interstitial and perilobular necrosis and extensive haemorrhages, with separation of the interstitium, mild reactive inflammation at the periphery of the pancreatic lobules. Liver showed multifocal foci of vacuolar degeneration, lipidic accumulation, sometimes associated to hepatocyte necrosis. A diagnosis of acute severe hemorrhagic-necrotizing pancreatitis (or acute pancreatic necrosis) associated with pancreatic and hepatic lipidosis was made. To the best of our knowledge, this represents the first case report of acute lethal pancreatitis in an Asian palm civet. Although the exact cause of the disease remains undetermined, a hypothesis of the cause and pathogenesis is discussed, pointing out dietary indiscretion and consequent overweight as possible important risk factors.
