L87.8: Other transepidermal elimination disorders

Transepidermal elimination disorders, coded as L87.8, refer to a collection of rare skin disorders. These conditions occur when certain substances, usually ones that are foreign or should not be in the skin, are eliminated from the body through the top layer of skin. This process typically occurs when the body is trying to expel these abnormal substances. Presentation of these disorders is often characterized by changes or abnormalities found on the skin's surface, which can include rashes, bumps, or discoloration. In some cases, the affected skin may also be rough, scaly, or itchy. These disorders can vary greatly from person to person and can evolve over time. Some people may only have mild symptoms, whereas others might experience more severe skin changes. The precise cause of these disorders is not fully understood, but they can sometimes be associated with underlying diseases, such as cancer or autoimmune conditions.
