Burns are classified as partial or full thickness depending upon the depth to which the skin has been subjected to injury. In partial thickness wounds, only the superficial layers of the epidermis are subjected to injury. Cells show evidence of coagulation necrosis and are converted into a uniform pink staining material. In full thickness burns, the entire epidermis, parts or all of the dermis, and the subcutaneous tissue may be injured. As with a particular thickness burn, the tissue involved is converted into a homogenously staining material.
Healing depends on the depth of the burn.
