Lichen Treatment

Patients with lichen sclerosus of nongenital skin often do not need treatment because the symptoms are very mild and usually go away over time. The amount of time involved varies from patient to patient.

However, lichen sclerosus of the genital skin should be treated, even when it is not causing itching or pain, because it can lead to scarring that may narrow openings in the genital area and interfere with either urination or sexual intercourse or both. There is also a very small chance that skin cancer may develop within the affected areas.

In uncircumcised men, circumcision is the most widely used therapy for lichen sclerosus. This procedure removes the affected skin, and the disease usually does not recur.

Prescription medications are required to treat vulvar lichen sclerosus, nongenital lichen sclerosus that is causing symptoms, and lichen sclerosus of the penis that is not cured by circumcision. The treatment of choice is an ultrapotent topical corticosteroid (a very strong cortisone cream or ointment). These creams or ointments may be applied daily for several weeks, which will be sufficient to stop the itching. However, long-term but less frequent applications (sometimes as infrequently as twice a week) will be needed to keep the lesions from reactivating and to help restore the skin's normal texture and strength. Treatment does not reverse the scarring that may have already occurred.

Because prolonged use of ultrapotent corticosteroid creams and ointments can cause thinning and redness of the skin, give rise to "stretch marks" around the area of application, and predispose individuals to vulvar yeast infections, periodic followup by a doctor is necessary.

Young girls may not require lifelong treatment, since lichen sclerosus can sometimes, but not always, disappear permanently at puberty. Scarring and changes in skin color, however, may remain even after the symptoms have disappeared.

Ultrapotent topical corticosteroids are so effective that other therapies are rarely prescribed. The previous standard therapy was testosterone cream or ointment, but this has been proven to produce no more benefit than a placebo (inactive) cream. Prolonged use of the testosterone cream or ointment can cause masculinization (low-pitched voice, increased coarse facial hairs). Another hormone cream, progesterone, was previously used to treat the disease, but has also been shown to be ineffective. Retinoids, or vitamin A-like medications, may be helpful for patients who cannot tolerate or are not helped by ultrapotent topical corticosteroids.

Tacrolimus (Protopic) ointment has been reported to benefit some patients, but more research is needed to confirm this. Tacrolimus is a steroid-free ointment; it is not a corticosteroid. Tacrolimus has no apparent side effects other than local irritation in some patients.

There are some early indications that different forms of ultraviolet light treatments, with or without psoralens (pills that intensify the effect of ultraviolet A light), may be effective and well-tolerated treatments for some patients with lichen sclerosus on nongenital skin.

Patients who need medication should ask their doctor how the medication works, what its side effects might be, and why it is the best treatment for their lichen sclerosus.

For women and girls, surgery to remove the affected skin is not an acceptable option because lichen sclerosus comes back after removal. Surgery may be useful for scarring, but only after lichen sclerosus is controlled with medication.

Sometimes, people do not respond to the ultrapotent topical corticosteroid. Other factors, such as low estrogen levels, an infection, irritation, or allergy to the medication, can keep symptoms from clearing up. Your doctor may need to treat these as well. If you feel that you are not improving as you would expect, talk to your doctor.
