Question: 1 / 400

Which of the following describes excoriation?

Thickening of the skin

Area of the skin without epidermis

Inflammation of the dermis

Area in which epidermis is missing exposing the dermis

The term "excoriation" specifically refers to a condition in which the epidermis—the outermost layer of skin—is damaged, resulting in an area where this layer is missing. This process exposes the dermis underneath. It often occurs due to scratching, rubbing, or other forms of trauma to the skin. Understanding that excoriation leads to an actual breach of the epidermis helps to distinguish it from similar conditions, such as inflammation of the dermis, thickening of the skin, or simply designated areas of skin without epidermis. Recognition of this point is critical because accurate identification of such skin conditions plays a significant role in infection prevention and control practices.
