What is a fibrous exudate?

Cellulosic inflammatory exudates contain a lot of cellulose. Due to the severe injury of vascular wall, a large amount of fibrinogen exudes out of the blood vessels and turns into fibrin (cellulose). Lesions often occur in the mucosa, serosa and lung. Cellulitis of mucous membrane (such as diphtheria, bacillary dysentery), exudative cellulose

The massive exudation of cellulose indicates that capillaries and venules are seriously damaged, and the permeability is significantly increased. A large amount of fibrinogen exudes out of the blood vessels and is transformed into cellulose under the action of tissue factors released by necrotic tissue, so it is called cellulosic inflammation.

Cellulosic inflammation is mostly caused by some bacterial toxins (such as diphtheria, dysentery and pneumococcal toxins) or a variety of endogenous and exogenous toxins (such as uremic urea and mercuric chloride poisoning). It often occurs in mucous membrane (pharynx, larynx, trachea, intestine), serosa (pleura, peritoneum and pericardium) and lung.
