degeneration

 [de-gen″ĕ-ra´shun]
deterioration; change from a higher to a lower form, especially change of tissue to a lower or less functionally active form. When there is chemical change of the tissue itself, it is true degeneration; when the change consists in the deposit of abnormal matter in the tissues, it is infiltration. adj., adj degen´erative.
caseous degeneration caseation (def. 2).
cerebromacular degeneration (cerebroretinal degeneration)
1. degeneration of brain cells and of the macula retinae, as occurs in tay-sachs disease.
2. any lipidosis with cerebral lesions and degeneration of the retinal macula.
colloid degeneration degeneration with conversion of the tissues into a gelatinous or gumlike material.
cystic degeneration degeneration with formation of cysts.
fatty degeneration deposit of fat globules in a tissue.
fibroid degeneration degeneration of a leiomyoma with subsequent fibrosis.
hepatolenticular degeneration Wilson's disease.
hyaline degeneration a regressive change in cells in which the cytoplasm takes on a homogeneous, glassy appearance; also used loosely to describe the histologic appearance of tissues.
hydropic degeneration a form in which the epithelial cells absorb much water.
lattice degeneration of retina a frequently bilateral, usually benign asymptomatic condition, characterized by patches of fine gray or white lines that intersect at irregular intervals in the peripheral retina, usually associated with numerous, round, punched-out areas of retinal thinning or retinal holes.
macular degeneration see macular degeneration.

fatty degeneration

n.
The accumulation of fat globules within the cells of a bodily organ, such as the liver or heart, resulting in deterioration of tissue and diminished functioning of the affected organ. Also called steatosis.

steatosis

A pattern of reversible cell injury resulting from hypoxia, toxic or metabolic insults, diabetes mellitus, obesity, and protein malnutrition, which consists of an accumulation of droplets of triglcerides/neutral fat in various solid organs—classically, the liver—and most common in alcoholics in whom the changes regress with abstention from alcohol. Fatty changes may also occur in other organs (e.g., heart, muscle, kidney).

fat·ty de·gen·er·a·tion

(fat'ē dĕ-jen'ĕr-ā'shŭn)
Abnormal formation of microscopically visible droplets of fat in the cytoplasm of cells, as a result of injury.
Synonym(s): adipose degeneration, steatosis (2) .

fatty degeneration

An abnormal tissue state featuring the accumulation of tiny fat droplets in the CYTOPLASM of cells. This occurs in severe infections, ISCHAEMIA, and severe nutritional lack and affects especially the liver and the heart.
