This kind of lesion may occur in many types of cancer, including breast cancer, melanoma, and squamous cell carcinoma, and especially in advanced disease. The characteristic malodorous smell is caused by dimethyl trisulfide. [1] It is usually not a fungal infection but rather a neoplastic growth with necrosing portions.
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.
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.
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 ...
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]
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 ...
Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells. Cell division is a normal process used by the body for growth and repair. A parent cell divides to form two daughter cells, and these daughter cells are used to build new tissue or to replace cells that have died because of ...
A gorilla licking a wound. Wound licking is an instinctive response in humans and many other animals to cover an injury or second degree burn [1] with saliva. Dogs, cats, small rodents, horses, and primates all lick wounds. [2] Saliva contains tissue factor which promotes the blood clotting mechanism.
