Ceroid deposits are found in liver, spleen,
intestinal mucosa, lymph nodes, bone marrow, and perithymic fat tissue.
Ceroid is a granular, autofluorescent substance, also known as lipofuscin. It is
thought to consist of cholesterol esters and glycolipids. It has been
identified in human tissues, within neurons and large macrophage-like cells
in association with several disease processes, for example, Neuronal
Ceroid Lipofuscinoses, including Batten Disease.
