“…74,[108][109][110] However, pancreatic neoplasia is rare in cats and is considered much less likely. 13 With chronic pancreatitis, pancreatic aspirates often are poorly cellular, because of the presence of fibrosis, which occasionally forms 1 or more mass-like lesions. 110 pass from the pancreatic surface to the omentum, mesentery, or visceral surfaces of the liver.…”

Consensus Statements of the American College of Veterinary Internal Medicine (ACVIM) provide the veterinary community with up-to-date information on the pathophysiology, diagnosis, and treatment of clinically important animal diseases. The ACVIM Board of Regents oversees selection of relevant topics, identification of panel members with the expertise to draft the statements, and other aspects of assuring the integrity of the process. The statements are derived from evidence-based medicine whenever possible and the panel offers interpretive comments when such evidence is inadequate or contradictory. A draft is prepared by the panel, followed by solicitation of input by the ACVIM membership which may be incorporated into the statement. It is then submitted to the Journal of Veterinary Internal Medicine, where it is edited prior to publication. The authors are solely responsible for the content of the statements.

“…It includes the first descriptions of a pancreatic pleomorphic sarcoma and a mast cell tumor in accessory spleens within the pancreas. Epithelial pancreatic neoplasms have been reported previously [29] and metastases of other carcinomas may affect the pancreas also (unpublished data). In general, pancreatic neoplasms may be accompanied by inflammation, and histopathological investigation is required to differentiate pancreatitis from an inflamed pancreatic neoplasm.…”

“…Further studies about pancreas-specific laboratory parameters in cats with lymphomas are necessary to investigate the prevalence of pancreatic involvement. Furthermore, inflammation was also reported in numerous feline epithelial pancreatic tumors [29] and as far as serological data were available, fPLI value was increased in several cases [32]. One may conclude that increased serological pancreatic enzymes can be indicative of an acute pancreatitis.…”

Tumors of mesenchymal origin are rarely reported in the pancreas. Therefore, this study characterized 17 feline non-epithelial pancreatic tumors, including clinical data, histopathology, and immunohistochemistry. Seventeen feline pancreatic tissue samples were investigated histopathologically and immunohistochemically. Selected pancreatic and inflammatory serum parameters, e.g., feline pancreatic lipase immunoreactivity (fPLI), 1,2-o-dilauryl-rac-glycero-3-glutaric acid-(6′-methylresorufin) ester (DGGR) lipase and serum amyloid A (SAA), were recorded, when available. The neoplasms were characterized as round (n = 13) or spindle (n = 4) cell tumors. Round cell tumors included 12 lymphomas and one mast cell tumor in ectopic splenic tissue within the pancreas. Lymphomas were of T-cell (n = 9) or B-cell (n = 3) origin. These cats showed leukocytosis (3/3) and increased fPLI (5/5), DGGR lipase (3/5) and SAA (4/5) values. Spindle cell tumors included two hemangiosarcomas, one pleomorphic sarcoma and one fibrosarcoma. The cat with pleomorphic sarcoma showed increased SAA value. Overall survival time was two weeks to seven months. These are the first descriptions of a pancreatic pleomorphic sarcoma and a mast cell tumor in accessory spleens within feline pancreas. Although rare, pancreatic tumors should be considered in cats presenting with clinical signs and clinical pathology changes of pancreatitis. Only histopathology can certainly distinguish solitary pancreatitis from a neoplasm with inflammation.

“…It commonly originates from the duct system, but may also originate from acinar tissue [ 13 ]. Conflicting data about the predominance of tubular carcinoma or acinar carcinoma in cats has been reported [ 14 ]. In domestic animals, the histogenesis of pancreatic adenocarcinoma has not been elucidated [ 6 ]; pancreatic adenocarcinomas are subtyped by the predominant arrangement of neoplastic cells [ 3 , 6 , 9 ].…”

Pancreatic adenosquamous carcinoma with invasion to the spleen in a cat

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.
