Abstract

Two 11-year-old cats, female Korean shorthair cat and male Siamese cat, with abdominal distention were presented to the local animal hospitals. Radiographic and ultrasonographic examinations revealed moderate to severe splenomegaly in both cats. In Korean shorthair cat, multiple masses were also existed on the anal and facial skin. Surgically excised whole spleens of two cats were requested for histopathologic examination. Histopathologically, numerous neoplastic round cells with cytoplasmic fine granules were widely infiltrated in the splenic parenchyma. The cytoplasmic granules were metachromatic on toluidine blue staining. These splenic masses were diagnosed as splenic mast cell tumors. Among them, Korean shorthair cat was remained healthy for at least 1 year after splenectomy. Because of no visiting of owner, we were only able to know the information for Siamese cat until 10 months after the splenectomy. To our best knowledge, this is the first detail case reports for splenic mast cell tumors in cats in Korea.
