Abstract

ABSTRACT A captive 12-year-old female maned wolf (Chrysocyon brachyurus), previously diagnosed with visceral leishmaniasis, developed severe myiasis in the right ear, followed by prostration and death. A firm solid nodule, measuring 1 x 3cm, was grossly observed in the pancreas. Histologically, there was neoplastic proliferation in the pancreas and pancreatic lymph node. Neoplastic cells had a neuroendocrine pattern, and were positive for gastrin and pancreatic polypeptide by immunohistochemistry. The wolf had also ulcerative gastritis. To the best of our knowledge is the first reported case gastrinoma in this species.
