Pancreatic adenocarcinoma in a dog with a maldigestion syndrome.

Maldigestion caused by a pancreatic enzyme insufficiency was diagnosed in a 10-year-old Scottish Terrier on the basis of clinical signs and gastrointestinal function test results. The histologic diagnosis was pancreatic adenocarcinoma. Maldigestion is an unusual manifestation of this malignancy, particularly in the absence of other clinical signs. However, pancreatic neoplasia should be considered in aged dogs that develop exocrine insufficiency.
