lichen simplex

lichen simplex

Hardened and thickened skin epidermis caused by abnormally persistent scratching. This is usually a response to some long-term (chronic) skin condition but may be the result of mental agitation and the establishment of a scratch-itch-scratch-itch cycle. Lichenification soon disappears if scratching can be avoided.
