Basics and possible causes
NecrosisNecrosis is the Death of tissue in a living organism, caused by factors such as injury, infection, or lack of blood supply. Necrotic tissue can cause Inflammatory conditions and further health problems. occurs when the blood supply to an area of skin is interrupted, meaning the tissue is no longer adequately supplied with oxygen and nutrients. Loss of blood supply can be triggered by a variety of causes, including physical injuries, infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease., or toxicToxic means "poisonous" and refers to substances that can have harmful effects on the body, including damage to organs, cells, or disruption of metabolic processes. influences.
A common cause of necrosisNecrosis is the Death of tissue in a living organism, caused by factors such as injury, infection, or lack of blood supply. Necrotic tissue can cause Inflammatory conditions and further health problems. in cats is traumaA trauma refers to a physical injury or damage caused by external force.

Certain systemic diseases, such as diabetes mellitus, can increase the risk of developing skin necrosisNecrosis is the Death of tissue in a living organism, caused by factors such as injury, infection, or lack of blood supply. Necrotic tissue can cause Inflammatory conditions and further health problems. because they impair circulation. Autoimmune diseasesAutoimmune diseases are conditions in which the immune system mistakenly attacks the body's own cells or tissues as if they were foreign substances. Examples in dogs and cats include autoimmune hemolytic anemia and systemic lupus erythematosus. that lead to an abnormal immune responseAn immune response is the immune system's reaction to foreign substances (antigens), such as microorganisms or proteins. It involves a series of processes aimed at recognizing, fighting, and eliminating these antigens. can also attack healthy skin tissue and cause it to die.
Typical accompanying symptoms
- Non-healing Wounds: These can be open, weeping, or crusted areas on the skin that do not heal despite care.
- Discoloration of the skin: Necrotic tissue can become darkly discolored, often black or brown, indicating the dying process.
- Foul odor: Dead tissue can develop a characteristic, unpleasant smell that indicates infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. or decomposition.
- Swelling and redness: The areas around the necrosisNecrosis is the Death of tissue in a living organism, caused by factors such as injury, infection, or lack of blood supply.
