Lichenization

Lichenization is a skin condition characterized by thick, rough, leathery skin with a pattern of raised bumps or lesions. It often appears on areas of the body that are exposed to friction or pressure such as the elbows, knees, and lower back. It typically develops gradually, beginning as small, flat, scaly patches that become raised and thickened over time. It is often accompanied by itching, burning, and pain. Lichenization can be caused by a variety of factors, including allergies, skin disorders, and autoimmune diseases.
