L20-L30: Dermatitis and eczema
L28: Lichen simplex chronicus and prurigo
Lichen simplex chronicus and prurigo are skin conditions that typically result from chronic scratching or rubbing of the skin. Lichen simplex chronicus is characterized by thickening and darkening of the skin and is often seen in areas such as the ankles, wrists, and the back of the neck. Prurigo, on the other hand, presents as small, itchy bumps that may evolve into thickened nodules. Both conditions can be caused by a number of factors, including environmental irritants, stress, allergies, or other underlying skin conditions. Symptoms generally include severe itching, darkening and scaling of the skin, and, in the case of prurigo, nodules or bumps. Both of these conditions are chronic and can impact quality of life due to constant itching and discomfort. The exact cause of these diseases is often unknown and treatment aims to manage symptoms and reduce scratching to prevent skin damage.
