Lichen Simplex Chronicus
What is Lichen Simplex Chronicus?LSC (Lichen Simplex Chronicus), also called scratch dermatitis or neurodermatitis, is a skin condition caused by frequent, excessive scratching. It does not develop suddenly. This is a complication resulting from habitual scratching in the same area, causing skin to thicken and acquire a leathery texture. The affected area typically becomes hyperpigmented, meaning it is darker than the surrounding skin.
Causes of Lichen Simplex ChronicusThis condition can occur anywhere on the body and affect individuals of various ages. However, it is most prevalent among adults between the age of 30 and 50, and it usually develops on the lower legs, ankles forearms, wrists, inside of the elbows, behind the knees, or on the neck.
The direct cause is scratching. The term lichenification refers to changes in the skin resulting from either rubbing or scratching excessively. In many cases, the underlying cause of the chronic itch is a separate skin condition, such as psoriasis, eczema, or dry skin. It can also begin with something as simple as an insect bite or irritation from ill-fitting clothing. Scratching can actually aggravate the itch, triggering more scratching and beginning a repetitive cycle. For many people, itching can also be a physical symptom of stress or anxiety.
