Lichenification
Pronunciation: ly-ken-ih-fih-KAY-shun
Thickening and hardening of the skin with exaggerated surface markings, resulting from repeated scratching or rubbing.
Full Definition
Lichenification is a secondary skin change defined by the development of thickened, leathery skin with accentuated skin markings, arising as a consequence of chronic mechanical trauma such as persistent scratching or rubbing. It is a hallmark feature of chronic atopic dermatitis and lichen simplex chronicus. In dermatological descriptions, lichenification is classified as a secondary lesion (in contrast to primary lesions such as macules or papules). Editors should note the noun form is 'lichenification' and the adjectival form is 'lichenified'; 'lichenoid' describes a histological pattern and is not synonymous. The word is frequently misspelled as 'lichenification' with a double 'f' or as 'lichenifcation.'
Usage
Usage note: 'Lichenified' is the adjectival form. 'Lichenoid' is a histological descriptor (resembling lichen planus pattern) and must not be used interchangeably with 'lichenified.'
