exudate

 [eks´u-dāt]
a fluid with a high content of protein and cellular debris that has escaped from blood vessels and has been deposited in tissues or on tissue surfaces, usually as a result of inflammation.

ex·u·date

(eks'ū-dāt),
Any fluid or semisolid that has exuded out of a tissue or its capillaries, more specifically because of injury or inflammation (for example, peritoneal pus in peritonitis, or the exudate that forms a scab over a skin abrasion) in which case it is characteristically high in protein and white blood cells. Compare: transudate.
Synonym(s): exudation (2)
[L. ex, out, + sudo, to sweat]

exudate

Internal medicine A cell and protein-rich fluid that extravasates from the capillaries. See Hard exudate, Pleural exudate, Waxy exudate.

exudate

1. A protein-rich fluid, such as serum or pus, that has leaked from blood vessels or been discharged by cells or tissues.
2. The accumulation or deposition of such fluid in or on the tissues.

exudate

the material that comes from a cut pore or break in the surface of an organism, such as sweat or cellular debris.

Exudate

The type of pleural effusion that results from inflammation or other disease of the pleura itself. It features cloudy fluid containing cells and proteins.

exudate

A liquid or semisolid which has been discharged through the tissues to the surface or into a cavity. Exudates in the retina are opacities that result from the escape of plasma and white blood cells from defective blood vessels. They usually look greyish-white or yellowish and are circular or ovoid in shape. They are sometimes classified into three groups according to size: (1) punctate hard exudates, which often tend to coalesce. They are found in diabetic retinopathy, Coats' disease, etc.; (2) exudates of moderate size, such as 'cotton-wool or soft exudates' as, for example, in branch/central retinal vein occlusion, hypertensive retinopathy, etc. These 'exudates' have ill-defined margins and are actually areas of ischaemia containing cytoid bodies, unlike hard exudates which are generally lipid deposits; (3) larger exudates, as found in the severe forms of retinopathy.
