Caption

Severe xanthomatosis in Soat1^tm1Far/Soat1^tm1Far Ldlr^tm1Her/Ldlr^tm1Her (ACAT1-/-LDLR-/-) mice fed an atherogenic diet for 2 months. A: Appearance of double homozygous mutant mouse compared to Ldlr^tm1Her/Ldlr^tm1Her littermate control (ACAT1+/+LDLR-/-). The marked skin thickening gives the double homozygous mouse an obese appearance. B-D: In hematoxylin and eosin stained skin sections, no abnormalities were detected in littermate controls (B, x40); thickened skin and inflammation were present in double homozygous mice (C, x40; D, x100). The marked skin thickening in double homozygous mice (C and D) was associated with dermal edema and a pleomorphic inflammatory infiltrate with cholesterol clefts (D, thin arrows) and multinucleated giant cells (D, open arrows). E and F: Hematoxylin and eosin stained sections of brain of double homozygous mice demonstrating free cholesterol crystal deposits in the cerebellum (E, x10) and near the choroid plexus (F, x40).
