Types of cellular degeneration Macroscopically Microscopically Cellular swelling - No visible change - Individual cells swollen - Tissue bulges on sectioning - Pale cytoplasm or small clear vacuoles - Hydronic or vacuolar degeneration Fatty change - swollen - variable sized vacuoles from fat accumulation - Pale - Nuclei pushed to edge of cell - Friable - Greasy Types of necrosis What it looks like Gross description Caused by/examples Coagulation necrosis - firmer, drier on cut surface - bacterial toxins - Resembles outline of adjacent tissue - Infarction - Cells are larger + outline lost - Viral replication - Cytoplasm structure homogenous - Nucleus is lost Liquefactive necrosis - abscesses - progenic organisms - Pus- usually has a capsule - Bacteria - Dying neutrophils Caseous necrosis - white to grey to yellow in colour - mycobacterium tuberculosis - Dry and crumbly - Fungi - Mixture of coagulative + liquefactive Fat necrosis - areas of focal opacity - pancreatitis - Hard consistency - Traumatic necrosis - Diet related- associated with diets lacking antioxidants
