Large-scale retrospective studies allow for identification of disease trends, such as predisposing factors, typical clinical signs, and range of histologic lesions, which cannot be determined in individual case reports. Lesions of the endocrine pancreas of ferrets are extensively reported; however, there are no in-depth investigations of lesions in the exocrine pancreas. This retrospective analysis presents the histologic features, clinical signs, and concurrent diseases of lesions in the exocrine pancreas of ferrets. Seventy-seven lesions were reported and included acinar cell hyperplasia (n = 32), chronic pancreatitis (n = 16), acute pancreatitis (n = 13), acinar cell adenoma (n = 5), acinar cell carcinoma (n = 4), acinar cell atrophy (n = 3), presumptive acinar cell hypoplasia (n = 2), and lymphoma (n = 2). Our results demonstrate that acinar cell hyperplasia and chronic pancreatitis can both cause grossly visible pancreatic nodules. Hyperplasia was not associated with neoplastic transformation. In addition, acinar cell adenoma was slightly more common than carcinoma, which is contrary to most reports of neoplasia in ferrets. Our findings also suggest that acute pancreatitis can be a sequela to pancreatic biopsy and that there may be an association between chronic pancreatitis and diabetes mellitus in ferrets. Finally, zinc toxicosis was found to be an unlikely cause of pancreatitis in these ferrets based on zinc tissue concentration testing in a subset of cases.
