lipofuscinosis

Abnormal storage of any one of a group of fatty pigments.

Any disorder due to abnormal storage of lipofuscins.

• ceroid l. — an inherited disease in sheep, cattle, dogs and cats, characterized by blindness, mental dullness and abnormal behavior. There is atrophy of the brain with extensive accumulation of lipopigments (‘ceroid bodies’) in nervous tissue and later viscera as well. The comparable, though possibly not identical, disease in humans is also called Batten disease.
• hepatic l. — a deposit of lipofuscin in partly oxidized form in the livers of sheep, which gives them a deep black color and makes them unsaleable. The condition is common in areas where the mulga tree (Acacia aneura) grows and the leaves are fed to sheep as fodder.
