Himalayan cat. The cat was affected by hemorrhagic gastroenteritis caused by Fusobacterium necrophorum. Also, chronic renal failure (CRF) was demonstrated according to high levels of blood urine nitrogen (BUN), creatinine (Cr), as well as hypoproteinemia and anemia. In this respect, in urinalysis, urine specific gravity (USG) decreased while urea, creatinine and total protein levels increased. Moreover, the complete blood count (CBC) tests showed neutrophilia, monocytosis and lymphopenia. During an exploratory laparotomy, nine masses with a size of 1-5 mm and firm consistency were found to be scattered on the omentum. Histologically, the masses consisted of capillary-cavernous vessels with well-differentiated endothelial cells. No mitotic figures, hemorrhage, or necrosis were found, but there was focal lymphocytic infiltration in the parenchyma of the masses. Immunohistochemically, expression of vimentin and von Willebrand factor (vWF) was found in the endothelial cells, while the immunoreaction to smooth muscle actin (αSMA) was negative. These findings confirmed the diagnosis of hemangioma. To the best of the authors’ knowledge, this is the first report of feline omental hemangioma.
