Pancreatic adenocarcinoma in guinea fowl

Pancreatic adenocarcinoma is a rare neoplasm of poultry. This condition is hereby described in an adult male guinea fowl that died suddenly in a flock of apparently healthy birds. Necropsy showed severe ascites and nodular tissue growths on the serous membranes of some internal organs and in the parenchyma of the pancreas only. Histopathological sections of the organs had neoplastic cells arranged as tubular or glandular structures or cellular cords with fibrosis of the affected tissues. Some of the tubular structures contained periodic acid-Schiff positive secretions in their lumina. It was suspected that the neoplasm was of exocrine origin.
