What symptom is tissue necrosis

summary

After a minor operation, my wife suffered from tissue necrosis due to infection. I didn't know the situation at that time, but I was scared. I was worried about what happened to my wife's body. Let's take a look at the symptoms of tissue necrosis.

What symptom is tissue necrosis

Symptom 1: coagulative necrosis: the necrotic tissue becomes dry due to dehydration and protein coagulation, and turns into gray or yellowish white relatively dry solid coagulation body. It is common in ischemic necrosis infarction of heart, kidney, spleen and other organs. The necrotic foci were clearly demarcated from healthy tissues. The outline of tissue structure could be seen under light microscope.

Symptom 2: liquefying necrosis: some tissues are decomposed into liquid state by enzymes after necrosis, and can form necrotic sac, which mainly occurs in tissues with less protein and more lipid (such as brain) or more protease (such as pancreas). Liquefying necrosis in brain tissue is also called encephalomalacia.

Symptom 3: cellulose like necrosis: it is a kind of necrosis that occurs in the stroma, collagen fibers and the wall of small blood vessels. Under the light microscope, the tissue structure of the lesion disappeared and became granular, small strip or small piece of unstructured material with unclear boundary. It was strongly eosinophilic and looked like fibrin. Sometimes fibrin staining was positive. Common in acute rheumatism, systemic lupus erythematosus, glomerulonephritis and other allergic diseases.

matters needing attention

Necrosis can be directly caused by strong pathogenic factors, but most of them develop from reversible injury. The basic manifestations of necrosis are cell swelling, organelle disintegration and protein degeneration. The key to the treatment of tissue necrosis is to find the disease in time and deal with it in time.
