Systemic xanthomatosis associated with hyperchylomicronaemia in a cat

We report a case of systemic xanthomatosis in a 4-month-old domestic cat. The kitten presented with multiple cutaneous lesions and 'cream tomato soup' coloured blood. Necropsy revealed multiple, whitish, nodular lesions, compatible with xanthomas, on most of the abdominal organs (liver, spleen, kidney, adrenal glands, mesentery and colon). The diagnosis was confirmed by histopathological examination. This is the first report of granulomatous colitis associated with feline xanthomatosis.
