A Japanese domestic long-hair cat of about 8 years of age was presented with vomiting and hematochezia and was found to have significant hypereosinophilia. Bone marrow aspiration revealed moderate increases of eosinophilic lineages. Histopathological examination revealed mild eosinophilic and epitheliotropic T-lymphocytic infiltrations in the duodenum. Although the cat remained asymptomatic with only prednisolone administration, the cat presented with hematemesis, weight loss, and severe anorexia 512 days after the initial presentation. Subsequently, gastrointestinal perforation developed, and the cat died on Day 536. Histopathological examination of autopsy specimens revealed mixed cellular infiltration including eosinophils and neoplastic lymphocytes in the intestinal lymph nodes, intestine, liver, spleen, and pancreas. Immunohistochemical examination supports a diagnosis of intestinal T-cell lymphoma with severe hypereosinophilic syndrome.
