2017 ACVIM Forum Research Abstract Program

The median age of the cats was 9.5 years (min-max: 3 to 18 years). Sample quality was reported as very good in all cases. Histologic evaluation of the stomach revealed lymphoplasmacytic infiltration in all specimens evaluated, which was graded as minimal (1 cat), minimal to mild (2 cats), mild (3 cats), mild to moderate (2 cats), or moderate (2 cats). Histologic evaluation of duodenal biopsies revealed evidence of lymphoplasmacytic infiltration in 11 of 12 cats, which was described as minimal to mild (3 cats), mild (1 cat), mild to moderate (4 cats), or moderate (3 cats). On assessment of duodenal specimens 1 cat was diagnosed as a having diffuse low-grade lymphoma. Architectural changes were present in 8 of 10 gastric and 12 of 12 duodenal sections. These consisted of fibrosis (8 cats) in gastric specimens and lacteal dilation (1 cat), crypt abscesses (1 cat), fibrosis (3 cats), and crypt hyperplasia (11 cats) in duodenal specimens.
