Which type of post-mortem change is indicated by the appearance of a green discoloration in the abdomen?

• A. Rigor mortis
• B. Hypostasis
• C. Decomposition
• D. Putrefaction

Answer: (D)

The appearance of a green discoloration in the abdomen is an indicator of putrefaction, which is a process that occurs during decomposition. Putrefaction is primarily caused by the action of bacteria and microorganisms as they break down the body's tissues after death. This process leads to the production of gases and compounds that can cause various visible changes, including discoloration, skin blisters, and a foul odor.

The green color is often associated with the breakdown of hemoglobin, leading to the formation of sulfhemoglobin or other pigments resulting from the anaerobic bacteria present in the intestines. These bacteria create a favorable environment for the rapid breakdown of organic matter, which is characteristic of putrefaction.

Other types of post-mortem changes, such as rigor mortis and hypostasis, do not lead to this specific green abdominal discoloration. Rigor mortis refers to the stiffening of muscles after death due to chemical changes in the muscle fibers, while hypostasis indicates the settling of blood to dependent areas of the body, resulting in a purplish discoloration but not green. Decomposition encompasses a broader range of changes, but putrefaction specifically focuses on the processes driven by bacteria, making it the most accurate description of the observed symptom.
