Caseous necrosis, a type of cellular death, results in areas of dead tissue that can be likened to cheese in structure and appearance, according to Drugs.com. It occurs in organs affected by an inflammatory disease, such as tuberculosis.
The processes leading to caseous necrosis leave the affected tissue completely destroyed. When viewed under a microscope, the cells of the tissue are fragmented and the architecture of the tissue is not preserved. Often, the area of necrosis is surrounded by a layer of immune cells and by another layer of fibrous tissue, explains the Department of Pathology at Creighton University.
The typical structure of areas of caseous necrosis and their surroundings is a result of the immune system attempting to enclose disease-causing microbes, claims the Journal of Immunology Research.
