Which term is not an example of necrosis?

• A. Necrobiosis
• B. Necrosis
• C. Gangrene
• D. Decubitus Ulcers

Answer: (A)

Distinguishing terms for tissue death and related processes. Necrosis is the death of cells or tissue due to injury or loss of blood supply. Gangrene represents extensive necrosis, usually with infection and decomposition of tissue. Decubitus ulcers are pressure-induced breaks in the skin and underlying tissue that can progress to necrosis, but they are not necrosis themselves—they are ulcers caused by prolonged pressure and ischemia. Necrobiosis is not a form of necrosis; it refers to a regulated degenerative change where cells die in a controlled way, a distinct process from acute necrosis. Therefore, the term that is not an example of necrosis is necrobiosis.
