Caseous necrosis or caseous degeneration[1] (/ˈkeɪsiəs/)[2] is a unique form of cell death in which the tissue maintains a cheese-like appearance.[3] Unlike with coagulative necrosis, tissue structure is destroyed. Caseous necrosis is enclosed within a granuloma. Caseous necrosis is most notably associated with tuberculoma. The dead tissue appears as a soft and white proteinaceous dead cell mass.
