T32.2: Corrosions involving 20-29% of body surface

Corrosions involving 20-29% of body surface, as described by its name, is a skin condition where around one-fifth to almost one-third of a person's total body surface has been affected by some degree of damage due to contact with corrosive substances. These substances, which can be either acidic or alkaline, cause the skin to break down leading to what medical professionals term as corrosion injuries. Symptoms include pain, blisters, and redness, with skin appearing white or charred in severe cases. The severity of the injury and the affected area depend on the type of corrosive substance, its concentration, the length of exposure, and the location on the body it has occurred. Corrosion burns can reach deep layers of skin, sometimes even affecting muscles and bones. This condition is regarded as a medical emergency due to the risk of complications such as infection and shock, and the need for immediate intervention to halt the corrosive process.
