T22.6: Corrosion of second degree of shoulder and upper limb, except wrist and hand

Corrosion of the second degree to the shoulder and upper limb, excluding the wrist and hand, is a type of injury that results from contact with corrosive substances. This condition affects the skin and underlying tissues of the shoulder or upper arm and is characterized by more severe damage compared to first-degree corrosion. General symptoms include noticeably painful, red, swollen skin, and the formation of blisters. Unlike a first-degree corrosion, a second-degree corrosion injures both the outer layer of skin (epidermis) and the layer underneath (dermis), leading to more profound tissue damage. This damage may manifest as whitish or splotchy skin and the injury area might seep fluid. Progression of the condition, without proper treatment, can lead to infection, scarring, and in some cases, functional impairment of the affected area. It's crucial to understand that this kind of corrosion injury is often caused by chemical burns which occur once certain harsh substances come into contact with the skin.
