Lichen simplex chronicus (LSC) (also known as neurodermatitis) is a skin disorder characterized by chronic itching and scratching. The constant scratching causes thick, leathery, darkened, (lichenified) skin. This condition is associated with many factors, including the scratch-itch cycle, psychological stressors, and atopy. LSC is more common between ages 35 and 50 and is seen approximately twice as often in women compared to men.

Ngokungafani nesinye isimo esilumayo esibizwa ngokuthi prurigo nodularis (PN) , okubonakala njengamaqhubu asakazeka ezingxenyeni ezihlukahlukene zomzimba, i-LSC ivamise ukukhawulelwa ezindaweni ezithile noma ezindaweni ezimbalwa. Nakuba i-LSC ngezinye izikhathi ibizwa ngokuthi i-neurodermatitis, ehlanganisa nezinye izimo zokuluma okuhlala isikhathi eside. LSC is a localized skin disorder clinically characterized by lichenified plaques of skin often accompanied by overlying excoriations. These plaques can become discoloured, with varying shades of erythema ranging from pink to dark brown. Over a longer course, it may transform into a hypopigmented plaque with a darker border. They are localized to specific areas of the body as one or a few plaques. This is in contrast to prurigo nodularis (PN), another chronic pruritic condition, which is frequently more broadly distributed across multiple regions of the body as nodules. While LSC may sometimes be referred to as a neurodermatitis, which encompasses other chronic itchy conditions.
