Lichen simplex is a localized, well-circumscribed area of thickened skin (lichenification) resulting from repeated rubbing, itching, and scratching of the skin.
A solitary plaque of lichen simplex is circumscribed, somewhat linear or oval in shape, and markedly thickened. It is intensely itchy. Some places often get these lesions, for example, the back of scalp and neck, the gentials, or the wrists/forearms.
Both Chinese herbal medicine and acupuncture can bring relief to a person suffering from lichen simplex.
