Hyperlipoproteinaemia associated with atherosclerosis and cutaneous xanthomatosis in a cat.
Bilateral uveitis and multiple xanthomas (fat deposits in the skin) are described in a 3.5-year-old ovariohysterectomized female Persian cat. The cat had been treated for 2 years with corticosteroids. Examinations included a routine blood chemistry profile, radiographic examination of the thorax and abdomen, histopathological examination of multiple skin punch biopsies, and analysis of blood lipid components by cellulose-acetate electrophoresis and by preparative ultracentrifugation studies. Total lipid values were 23 g/l. Ultracentrifugation studies indicated strongly elevated VLDL and LDL fractions and a decreased concentration of the HDL fraction. Because of sudden blindness the cat was euthanized at the request of the owner. Autopsy revealed massive atherosclerotic changes in the large abdominal vessels, the wall of the aorta, and the coronary vessels. Although the exact pathogenesis remains uncertain, these unusual findings might be explained by a primary hyperlipoproteinaemia, complicated by long-term use of corticosteroids.
