Marbling Of Skin Forensic

Marbling over the trunk and limbs is another feature of postmortem skin decomposition caused by the spread of bacteria through the venous system.

Marbling of skin forensic.

See air embolism pulmonary barotrauma. Skin breaks down leading to blistering and skin slippage and bacterial growth in soft tissues with gaseous formation leads to bloating of the body. This process can be seen as discolouration of the vessels marbling. Understanding common postmortem changes and the variables that affect them allows the forensic pathologist to more accurately estimate the postmortem interval.

Onset of lividity its location and color provide information on the time and cause of death. Normal postmortem changes in the skin are described along with pseudopathology and damage from. Although these changes proceed in a relatively orderly fashion a variety of external factors and intrinsic characteristics may accelerate or retard decomposition.

Correct forensic terminology and documentation of dermatologic findings is of critical importance in forensic investigations.

Postmortem skin changes include livor mortis vibices tardieu spots and marbling. The skin may reveal clues to the identity of an individual and the time and method of death or injury.

Decomposition is the process by which dead organic substances are broken down into simpler organic or inorganic matter such as carbon dioxide water simple sugars and mineral salts the process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere bodies of living organisms begin to decompose shortly after death. Internal pressures build up forcing decomposition fluids from the lungs through the mouth and nose purge fluid. From 60 to 72 hours postmortem the body exhibits generalised swelling and bloating from increased gas production by bacteria.
