ceroid

Pronunciation: sē′royd

Definition: A waxlike, golden, or yellow-brown pigment first found in fibrotic livers of choline-deficient rats, and also known to be present in some cirrhotic livers (and certain other tissues) of human beings. Ceroid 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]
