Lichen simplex chronicus usually appears as a solitary patch with a round or oval shape.
The skin will look dry and scaly with a thick, leathery texture and feel.
The patch is often hyperpigmented (darker than the surrounding skin).
There will often be visible scratch marks on or around the patch.

What Triggers Lichen Simplex Chronicus?
Lichen simplex chronicus is a symptom rather than a disease.
It is more common in adults and is fairly uncommon in children.
It affects females more than males and is most often seen between the ages of 30 and 50.
The primary aim of the diagnosis is to pinpoint the underlying cause.
The symptom may occur on its own or develop secondary to skin diseases like psoriasis or eczema.
In some cases, the cause may be psychosomatic and due to underlying anxiety, stress, or depression.
