Lichenification is thick hard skin with exaggerated natural skin lines, typically from repeated scratching or rubbing.[1][2] Sites of the body prone to rubbing such as the neck, wrists, hands, forearms, waist, genital area, legs and tops of feet, are particularly susceptible.[3] Its presence is usually a clue to another problem.[3]
It may occur in lichen simplex chronicus, or be due to other conditions which include eczema, psoriasis, excessive dry skin, pityriasis rubra pilaris, anxiety, and obsessive-compulsive disorders.[3] If generalised, it may be a sign a more serious condition such T-cell lymphoma and Sézary syndrome.[3] It may require tests to find out why the excessive itch.[3]
