Signs and symptoms
People burdened with LSC report Itch, followed by uncontrollable scratching of the same body region, excessively.
Causes
This is a skin disorder characterized by a self-perpetuating scratch-itch cycle:
-
It may begin with something that rubs, irritates, or scratches the skin, such as clothing.
-
This causes the person to rub or scratch the affected area. Constant scratching causes the skin to thicken.
-
The thickened skin itches, causing more scratching, causing more thickening.
-
Affected area may spread rapidly through the rest of the body.
Many hypothesize LSC has a psychosomatic origin.
Diagnosis
LSC is typically diagnosed by careful observation and history taking.
Treatment
Treatment is aimed at reducing itching and minimizing existing lesions because rubbing and scratching exacerbate LSC. The itching and inflammation may be treated with a lotion or steroid cream (such as Kenalog or Betamethasone) applied to the affected area of the skin.
