A waxlike, golden or yellow-brown pigment first found in fibrotic livers of choline-deficient rats, and also known to be present in some of the cirrhotic livers (and certain other tissues) of human beings. C. is acid fast, insoluble in fat solvents, and probably a type of lipofuscin, although differing from true lipofuscins by failing to stain with Schmorl ferric-ferricyanide reduction stain; it also exhibits autofluorescence. Accumulates in Hermansky-Pudlak syndrome. [L. cera, wax, + G. eidos, appearance]
