Abstract
A 26-year and 6-month-old male sika deer that was kept at the Showa Park, Tokyo, Japan,
collapsed and died of severe disease wasting and severe tabefaction. Grossly, numerous
masses, 0.3–1.0 cm diameter, were dispersed throughout the liver. The multiple masses were
composed of tumor cells, which had hypochromatic nuclei and abundant faintly eosinophilic
cytoplasm, arranged in nests of various sizes. Immunohistochemically, tumor cells were
positive for cytokeratin, chromogranin A, synaptophysin and gastrin. Ultrastructurally,
the cytoplasm of the tumor cells contained abundant membrane-bound electron-dense
granules. A metastatic lesion was observed in the renal, hepatic and pancreatic lymph
nodes. On the basis of these findings, this tumor was diagnosed as a neuroendocrine
carcinoma with metastases to the lymph nodes.

Abstract
A 15-year-old neutered male Persian cat was presented with recurrent hematemesis and
melena. Abdominal ultrasonography and computed tomography revealed a mass in the proximal
descending duodenal wall. Endoscopic examination revealed hemorrhage on the luminal side
of the mass. Fine-needle aspiration of the mass was performed. Microscopic analysis
revealed a cluster of cells with oval nuclei and indistinct cell borders, suggesting a
neoplastic disease of neuroendocrine origin. The mass located near the major duodenal
papilla was partially resected, and the bleeding was stopped by cauterization. However,
the surgical procedures could not control the hemorrhage from the tumor mass, and the cat
died of severe anemia. Immunohistopathological analysis revealed that the tumor was a
duodenal carcinoid.

Abstract
A 35-mo-old spayed female mixed-breed cat with continuous vomiting, emaciation, and abdominal distention for 2 wk was presented to a private veterinary clinic for evaluation. At 71 d after the initial visit, the cat died with anemia, jaundice, and hypoalbuminemia, and was subjected to autopsy. Grossly, numerous firm masses, 0.5-2.5 cm diameter, were randomly located in the left lobe of the pancreas. Histologic examination revealed that the pancreatic mass consisted of 2 tumor cell types: mostly small round cells with a minority of epithelial cells. The small cells were arranged in nests of various sizes, which were separated by thin fibrous stroma, and had small, round, hyperchromatic nuclei, scant cytoplasm containing argyrophilic granules, and often formed rosettes. The epithelial cells formed luminal structures. Metastases were observed in the liver, greater omentum, and pancreatic, gastric, pulmonary, and mediastinal lymph nodes. Immunohistochemical examination revealed that the small cells were positive for vimentin, neuron-specific enolase, chromogranin A, cytokeratin (CK) AE1/AE3, and trypsin, whereas the epithelial cells were positive for AE1/AE3, trypsin, CK19, and nestin. Ultrastructurally, the small cells contained abundant electron-dense granules, ~200 nm diameter, whereas the epithelial cells had apical microvilli and numerous zymogen granules, ~300 nm diameter. These findings indicated that the tumor was a pancreatic neuroendocrine carcinoma with exocrine differentiation and systemic metastases.
