Lichen simplex or lichenification – http://id.who.int/icd/entity/1276237557
If a circumscribed area of skin is subjected to repeated rubbing or scratching, localised epidermal thickening or lichenification will ensue. This may occur as a discrete patch within normal skin (lichen simplex) but frequently complicates eczema or other pruritic dermatoses.
