Abstract
ABSTRACT: Pancreatic cysts are rare in both humans and animals. They are defined as an enclosed structure externally surrounded by a capsule, internally coated with a cuboidal epithelium and filled with liquid or semi-solid content. This case described the clinical and pathological characteristics of a pancreatic cyst in a feline. A mixed breed cat with a history of recurrent vomiting was attended. Physical examination revealed pain on abdominal palpation. Abdominal ultrasonography showed a cystic, anechoic structure with well-defined edges located in the left cranial abdomen and in close contact with the duodenum and pancreas. Partial pancreatectomy was performed. Microscopically, the structure was surrounded by fibrous material, coated with cuboidal to columnar epithelium, and containing eosinophilic material. Although, pancreatic cyst is rare in animals, they should be included in the differential diagnosis of causes of vomiting in young cats.

RESUMO: Os cistos epiteliais pancreáticos são raros em humanos e animais, e são definidos como estruturas encapsuladas rodeadas por epitélio cuboidal, preenchido por substância líquida
Pancreatic cysts or true pancreatic cysts are rare in animals and humans (HINES et al, 1996; SMITH et al, 1998; VANEKVORT et al, 1999; COLEMAN et al, 2005; KHAN et al, 2011), and may occur due to benign, mainly malformation, and malignant processes (KHAN et al, 2011)
Pancreatic pseudocysts are characterized by inflammatory fluid collections and the cystic lesion has no epithelial lining
Summary
RESUMO: Os cistos epiteliais pancreáticos são raros em humanos e animais, e são definidos como estruturas encapsuladas rodeadas por epitélio cuboidal, preenchido por substância líquida. Surgery might be indicated for treatment and subsequent histopathological diagnosis (COLEMAN et al 2005; BRANTER et al 2010) This e report described the clinical and pathological characteristics of a pancreatic cyst in a mixed-breed cat emphasizing the efficiency of the surgical approach. Vomiting was the main clinical sign observed in this case and; nonspecific, it seemed to be the main clinical sign associated with the presence of pancreatic cysts or pseudocysts in cats (BRANTER et al, 2010; COLEMAN et al, 2005; HINES et al, 1996; VANENKEVORT et al, 1999; BRÜCKNER 2019). Cystic lesions of the pancreas are more common in humans than in animals and only few cases of pancreatic cyst in cats were described. Clinicians should have a systematic approach for establishing a diagnosis, but exploratory surgery can be performed in an attempt for concomitant diagnosis and treatment
