Exocrine pancreatic neoplasia in the cat: a case series.

Eight cases of feline pancreatic adenocarcinoma and two cases of pancreatic adenoma were reviewed. The adenomas were incidental findings. Most cats with adenocarcinomas had anorexia (75%) and vomiting (63%), while 38% had abdominal pain, a palpable abdominal mass, and/or jaundice. Diagnostic abnormalities included leukocytosis, hyperglycemia, increased alanine aminotransferase activity, poor serosal detail on abdominal radiography, and an abdominal mass effect on ultrasonography. The majority of cats with carcinomas had metastases (mostly to liver, lung, and small intestine), and all were euthanized or died within 7 days of diagnosis. Clinically, feline pancreatic carcinoma may be difficult to distinguish from feline pancreatitis.
