T21.5: Corrosion of first degree of trunk

Corrosion of the first degree of the trunk refers to skin damage caused by exposure to chemicals or extreme temperatures, typically occurring on the chest, back, or abdomen. This condition is characterized by an area of your skin turning red and swelling, feeling painful and warm to touch, which are signs of a mild burn or corrosion. The areas exposed to the corrosive agent may appear moist or shiny, and they may also be sore or tender. This injury only involves the skin's outer layer, or the epidermis, and does not extend deeper into the skin. Although this condition is painful, it usually does not cause any long-term damage to the skin as the burn site typically heals within 5-7 days without the need for medical intervention. However, the severity can vary depending on the type and duration of contact with the corrosive agent.
