Maceration is defined as the softening and breaking down of skin resulting from prolonged exposure to moisture. It was first described by Jean-Martin Charcot in 1877. [ 1 ] [ 2 ] Maceration is caused by excessive amounts of fluid remaining in contact with the skin or the surface of a wound for extended periods.
Maceration, in chemistry, the preparation of an extract by solvent extraction; Maceration, in biology, the mechanical breakdown of ingested food into chyme; Skin maceration, in dermatology, the softening and whitening of skin that is kept constantly wet; Maceration, in poultry farming, a method of chick culling
Maceration is a form of controlled putrefaction, a stage of decomposition in which the proteins of the body's cells are broken down and consumed by bacteria in anaerobic conditions. The temperature is usually maintained at a constant optimal temperature in an incubator. Maceration generates very strong and distasteful odors, and is therefore ...

Exudate from heavily draining wounds causes irritation of the periwound that may lead to maceration, excoriation, and otherwise compromise skin integrity. [ 6 ] [ 7 ] This type of damage is more common in chronic wounds due to exudate composition which differs from fluids produced in acute wounds or burns.
Later, as the condition worsens feet can start to swell and smell of decay as muscle and tissue become macerated. The feet often feel warm to the touch. [1] [7] Advanced trench foot often involves blisters and open sores, which lead to fungal infections; this is sometimes called jungle rot. It is marked by severe short-term pain when feeling ...
Foot maceration occur whenever exposed for prolonged periods to moist conditions. Large watery blisters appear which are painful when they open and begin to peel away from the foot itself. The heels, sides and bony prominences are left with large areas of extremely sensitive, red tissue, exposed and prone to infection.
Epidermoid cysts are usually diagnosed when a person notices a bump on their skin and seeks medical attention. The definitive diagnosis is made after excision by a pathologist based on microscopic appearance of a cystic lesion lined by cornified epithelium containing lamellated keratin without calcifications .
