This is composed of blood plasma that has seeped out of ruptured small blood vessels and the inflammatory fluid produced by injured and dying cells. [citation needed] Seromas are different from hematomas, which contain red blood cells, and abscesses, which contain pus and result from an infection. Serous fluid is also different from lymph.
Malignant (or cancerous) pleural effusion is effusion where cancer cells are present. [11] It is usually classified as exudate. Types of exudates: serous, serosanguineous, sanguineous, hemorrhaging and purulent drainage. Serous: Clear straw colored liquid that drains from the wound. This is a normal part of the healing process.
Healthy cells maintain a balance called homeostasis, constantly adjusting to various stressors and stimuli from their environment. When a cell can't adapt properly to these changes, it suffers a reversible injury. However, if the cell can't return to its normal state and continues to be exposed to stress or damage, the injury becomes irreversible.
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. [3] [4] Cancer can be difficult to diagnose because its signs and symptoms are often nonspecific, meaning they may be general phenomena that do not point directly to a specific disease process. [5]
What appears to be a chronic wound may also be a malignancy; for example, cancerous tissue can grow until blood cannot reach the cells and the tissue becomes an ulcer. [13] Cancer, especially squamous cell carcinoma, may also form as the result of chronic wounds, probably due to repetitive tissue damage that stimulates rapid cell proliferation ...
An eschar (/ ˈ ɛ s k ɑːr /; Greek: ἐσχάρᾱ, romanized: eskhara; Latin: eschara) is a slough [1] or piece of dead tissue that is cast off from the surface of the skin, particularly after a burn injury, but also seen in gangrene, ulcer, fungal infections, necrotizing spider bite wounds, tick bites associated with spotted fevers and exposure to cutaneous anthrax.
The blood of people killed by blood agents is bright red, because the agents inhibit the use of the oxygen in it by the body's cells. [2] Cyanide poisoning can be detected by the presence of thiocyanate or cyanide in the blood, a smell of bitter almonds, or respiratory tract inflammations and congestions in the case of cyanogen chloride ...
The two toxins together can cause destruction of red blood cells in blood vessels, damage to the integrity of the blood vessels, and suppression of heart function. [ citation needed ] The key Clostridium septicum virulence factor is a pore-forming toxin called alpha-toxin, though it is unrelated to the Clostridium perfringens alpha-toxin.
