Plain-English summary
An 11-year-old female mixed breed cat was diagnosed with a rare pancreatic tumor called acinar cell cystadenoma after showing signs of illness. The tumor was quite large, measuring 5.5 cm, and contained multiple cysts. This type of tumor is unusual in cats and was identified through microscopic examination and specific tests. Since this is the first reported case of this tumor in a cat, it highlights the need for further understanding of pancreatic tumors in pets.

Abstract
Cystic tumours of the pancreas are heterogeneous lesions with a spectrum of morphology and biological behaviour in people. These are poorly characterized in animals. A multicystic tumour of the pancreas was identified in an 11-year-old, female, mixed breed cat. The tumour was 5.5 cm in diameter and the largest cysts were 1.5 cm in diameter. Microscopically, the cysts were lined by single layered or pseudostratified, flat, cuboidal or columnar epithelial cells that occasionally formed papillary structures with a thin fibrous core. The tumour cells had eosinophilic granules in the apical cytoplasm, similar to zymogen granules, and the nuclei were uniform in size and shape. Mitotic figures were not observed. Immunohistochemically, the tumour cells expressed trypsin, but not cytokeratin 7. A diagnosis of acinar cell cystadenoma of the pancreas was made and this is the first report of this tumour in a cat.
