What is Necrosis?
Reviewed: Dr. Gromatzky
3. Caseous Necrosis
Caseous necrosis will lead to what is known as a granuloma. They are a result of a defense mechanism that tries to protect the body by isolating a threat such as a fungal or bacterial infection. One common cause of this is tuberculosis, which is a bacterial infection of the lungs. Some fungal infections can also cause the condition.
In cases of caseous necrosis, the tissue will typically take on the appearance of cottage cheese. There will be an area of dead tissue in the center, surrounded by a barrier that has a high concentration of lymphocytes and macrophages to help keep the rest of the body protected.
