Abstract
A 17-y-old Arabian mare was presented to the Auburn Large Animal Veterinary Teaching Hospital with a long-term history of intermittent mild recurrent colic that responded to medical treatment. CBC revealed mild lymphopenia; serum biochemistry findings were of increased gamma-glutamyl transferase and creatine kinase activities, hyperferremia, hyperglycemia, hypomagnesemia, and hypokalemia. Abdominocentesis was compatible with low-protein transudate. Due to the progression and duration of clinical signs, the owner elected euthanasia. Postmortem examination and histopathology confirmed a cholangiocarcinoma. The neoplastic cells were arranged in large cysts containing lakes of mucin that comprised 90% of the tumor volume; thus, a mucinous variant was determined. The neoplastic cells had strong cytoplasmic immunolabeling for cytokeratin 19 and lacked immunolabeling for hepatocyte paraffin 1, supporting bile duct origin. Cholangiocarcinomas are infrequent tumors in horses with nonspecific and slow progressive clinical signs, including recurrent colic. Mucinous cholangiocarcinomas are seldom reported in veterinary medicine and, to our knowledge, have not been reported previously in horses.

Abstract
The Tsushima leopard cat (Prionailurus bengalensis euptilurus) is a subspecies of the mainland leopard cat that lives on the small island of Tsushima, Japan. Captive breeding has been attempted in zoos in Japan because only approximately 100 animals remain in the wild and the Tsushima leopard cat is an endangered species. There are very few reports on diseases, including tumours, of this species. We analysed the deaths of 58 Tsushima leopard cats and confirmed that nine had neoplastic disease. The average age at death of the animals with neoplasia was 14 years and tumours were the primary cause of death in all animals. Eight of the nine cases involved primary tumours of the pancreas, liver, gallbladder, tongue and salivary glands, suggesting that Tsushima leopard cats may have a predilection for digestive system tumours. This is the first report of neoplastic disease in the Tsushima leopard cat.

J Comp Pathol 2023; 201:123-129. [PMID: 36812694 DOI: 10.1016/j.jcpa.2023.01.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 12/21/2022] [Accepted: 01/18/2023] [Indexed: 02/22/2023]
Abstract
The aim of this study was to characterize the pathological and immunohistochemical aspects of pancreatic carcinoma in cats, through a retrospective study. From January 2010 to December 2021, 1,908 cat necropsies were performed, in which 20 cases of exocrine pancreatic neoplasia were diagnosed (1.04%). Affected cats were mature adults and seniors, except for one 1-year-old cat. In 11 cases the neoplasm was a soft, focal nodule on the left (8/11) or right (3/11) lobe. In nine cases there were multifocal nodules throughout the pancreatic parenchyma. The size of the single masses ranged from 2 to 12 cm, and the multifocal masses from 0.5 to 2 cm. The most frequent tumour type was acinar carcinoma (11/20), followed by ductal carcinoma (8/20), undifferentiated carcinoma (1/20) and carcinosarcoma (1/20). On immunohistochemical evaluation, all the neoplasms were remarkably reactive to pancytokeratin antibody. The ductal carcinomas were strongly reactive for cytokeratins 7 and 20, which proved to be a good marker for pancreatic ductal carcinoma in cats. The main form of metastasis was abdominal carcinomatosis, with a marked invasion of blood and lymphatic vessels by neoplastic cells. Our findings reinforce the fact that pancreatic carcinoma should be rated highly in the differential diagnosis in mature adult and senior cats with abdominal masses, ascites and/or jaundice.

Abstract
A four-and-a-half-year-old female Scottish Fold cat underwent partial pancreatectomy with
en-bloc splenectomy. The resected specimen was a biphasic tumor that was diagnosed
histologically and immunohistochemically as pancreatic adenosquamous carcinoma (ASC), a
ductal carcinoma variant according to the WHO classification of tumors in humans. There
was a gradual transition between the adenocarcinoma component and the squamous cell
carcinoma component. The squamous cell carcinoma component comprised approximately 30–40%
of the tumor. A pancreatic tumor infiltrated into the gastrosplenic ligament and spleen
with regional lymph node and mesenteric metastases. Pancreatic ASC has not been reported
in animals. This is a case report of feline pancreatic ASC with splenic involvement.

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.

Primary Solid and Cystic Tumours of the Exocrine Pancreas in Cats. J Comp Pathol 2019; 169:5-19.

Abstract
Tumours of the exocrine pancreas are rare in cats and few cases are described in the literature. Cystic tumours of the pancreas are not included in the World Health Organization (WHO) international histological classification of tumours of domestic animals. The aim of this study was to characterize the pathology of primary epithelial tumours of the feline exocrine pancreas, with emphasis on cystic tumours. We reviewed tumours of the exocrine pancreas in 70 cats, including complete tumours or the entire pancreas (n = 18) and excisional biopsy samples of pancreatic tumours (n = 52). Macroscopically, the tumours were grouped as solid (n = 45) or cystic (n = 25). Solid tumours were subdivided into adenomas (n = 5) and carcinomas (n = 40) and cystic neoplasms into adenomas (n = 15), carcinomas (n = 7) and cases with diverse growth patterns (n = 3). All five grossly solid adenomas had acinar morphology, while the macroscopically solid carcinomas showed acinar (n = 17), tubular (n = 14) or mixed (n = 9) growth microscopically. Cystic adenomas had acinar (n = 2), tubular (n = 12) or mixed (n = 1) growth, while cystic carcinomas had exclusively tubular growth (n = 7). Three cases with cystic lesions showed diverse histopathological growth patterns. The clinical outcome was available in 57 cases. The majority of cats with carcinomas died or were humanely destroyed during or shortly after surgery (n = 32). However, 2/7 animals with cystic carcinomas showed longer survival times. Cats with cystic adenomas had survival times of up to 5 years. The results of this study show that cystic pancreatic tumours should be considered a differential diagnosis in cats with cystic intra-abdominal masses, even though these are not yet described in the WHO classification. Based on the relatively long survival times of cats with cystic adenomas, complete resection with subsequent histopathological examination is recommended.
