Lichen sclerosus is a chronic inflammatory skin disorder that generally affects the genital and anal areas, though it may appear on other parts of the body. It is marked by white, thinning patches of skin that can cause discomfort and lead to complications if untreated. 

Early diagnosis and proper management can help control symptoms and improve patients’ quality of life. If you’re preparing for the NEET PG exam, students need to understand what lichen sclerosus is, what causes it, how to diagnose and treat it.

Read on for more information. 

What is Lichen Sclerosus? 

Lichen sclerosus is a skin disorder targeting the genital area, typically the vulva in women and the penis in men. When it affects the penis, it is referred to as balanitis xerotica obliterans.

The disorder is commonly witnessed in women of middle age. Common symptoms include itching, discomfort, and visible changes to the skin in the affected region. Applying a corticosteroid cream or ointment usually helps relieve these symptoms effectively.

What are the Causes of Lichen Sclerosus?

The following are the causes of lichen sclerosus: 

• Genetic and Autoimmune Factors

It is common to see lichen sclerosus highly associated with autoimmune disorders, whereby the immune system attacks itself. Research indicates a potential genetic component, as the condition can sometimes be observed within families. 

People who are already suffering from autoimmune diseases, like vitiligo or thyroid problems, may be more likely to be affected by lichen sclerosus.

• Influence of Lifestyle and Diet

It is not believed that lifestyle and diet are direct causes of lichen sclerosus, although they can affect the severity of the condition . The condition may be aggravated by factors such as stress, poor diet and poor personal hygiene.

What are the Risk Factors of Lichen Sclerosus?

Lichen sclerosus may develop in people of all ages and genders, but some groups are at higher risk. These include:

• Women who experienced menopause
• Small children, especially those who are below 10 years of age
• Women with existing autoimmune conditions, such as underactive thyroid (hypothyroidism)
• Men who are not circumcised or who experience urinary incontinence
• Those with a family background of the condition

What are the Symptoms of Lichen Sclerosus?

Lichen sclerosus is indicated by the appearance of white and raised spots in places like the vulva, anus, foreskin or on the head of the penis (glans), etc. These patches can lead to itching, irritation, burning sensations, or general discomfort. 

Some of the other lichen sclerosus symptoms may include:

• Open sores or ulcers
• Swelling or inflammation
• Development of scar tissue
• Cracking of skin 
• Pain during urination (dysuria)
• Discomfort or pain during sexual activity
• A weakened urine stream
• Urine that sprays rather than flows normally
• Tightening of the foreskin
• Difficulty retracting the foreskin (phimosis)
• Unusual penile discharge not related to urine or semen

Though uncommon, lichen sclerosus may also appear on non-genital areas, including the neck, chest, torso, upper back, wrists, or even inside the mouth.

How to Diagnose Lichen Sclerosus?

Identifying lichen sclerosus usually starts with a comprehensive clinical assessment. This involves gathering a detailed medical history, including the presence of symptoms, any family history of dermatological conditions, and existing health issues. 

It is essential that there is a thorough physical examination of the involved areas of skin. Although clinical evaluation alone often suffices, further diagnostic tests may be employed to support the diagnosis:

• Blood Tests

These may be carried out to detect associated autoimmune disorders or to evaluate general health status.

• Skin Biopsy

A microscopic tissue sample (a small piece of affected skin) can be taken to make the diagnosis definite and rule out possible alternative disorders.

What are the Treatment Options for Lichen Sclerosus?

Lichen sclerosus treatment often includes the following:

• Topical Corticosteroids

These are medicated creams or ointments applied directly to the affected skin to reduce inflammation and discomfort. Clobetasol is one of the most frequently prescribed steroids.

• Phototherapy

This method involves the use of ultraviolet light, typically UVB (ultraviolet B radiation), from specialised lamps. It may help decrease inflammation and relieve itching.

• Immunosuppressive Medications

These treatments work by suppressing the immune system’s abnormal response. Tacrolimus ointment is commonly used in such cases.

• Surgical Intervention

Surgery might be recommended in some cases, depending on the area. For example, circumcision might be suggested when the foreskin is affected, while a urethroplasty could be necessary in cases where the urethra becomes narrowed.

Other non-pharmacological management includes:

• Lifestyle Adjustments

Adopting proper hygiene practices, steering clear of known irritants, and managing stress levels can assist in alleviating symptoms.

• Nutritional Support

Following a well-balanced diet that includes anti-inflammatory foods may contribute to improved skin health.

• Complementary Approaches

Some individuals report symptom relief through treatments such as acupuncture, herbal medicine, or other alternative therapies. Nevertheless, one should not forget that the approaches in question should be discussed with a medical expert.

How to Prevent Lichen Sclerosus?

Although there is no definite method to prevent lichen sclerosus, certain measures may help lower the likelihood of developing the condition or reduce symptom severity:

• Maintaining Proper Hygiene

Individuals must ensure the genital region remains clean and dry, which minimises irritation and improves overall skin health.

• Nutritional Support

Consumption of a balanced diet including plenty of fruits, vegetables, and whole grains may contribute to healthy skin.

• Managing Stress

Engaging in stress-reducing practices such as meditation, yoga, or therapy may help control symptom flare-ups.

• Routine Medical Reviews

Regular appointments with healthcare professionals can help detect any changes in the skin early.

• Vaccination Awareness

Keeping immunisations current may help prevent infections that could aggravate existing skin conditions.

FAQs About Lichen Sclerosus 

1. What can trigger a flare-up of lichen sclerosus?

The exact trigger of the appearance of lichen sclerosus attacks is still unclear, and irritation of the skin could be one of the possible contributing factors. A worsening of symptoms may also indicate that your current treatment, such as steroid creams, may need to be used more frequently or adjusted by the doctor.

2. Is surgery ever needed for lichen sclerosus?

Yes, when severe scarring or complications are witnessed, then surgery such as circumcision or urethroplasty can be done, especially if the foreskin or urinary function is affected.

3. Can lichen sclerosus disappear on its own?

Lichen sclerosus has no specific cure, although the itchiness and the sense of discomfort are easily solved with topical steroids. These medications often help prevent the condition from progressing. In some cases, particularly among young girls, the condition may resolve entirely around the time of puberty without a clear reason.

4. What types of clothing should be avoided with lichen sclerosus?

To prevent further irritation, it is best to steer clear of rough materials like wool or any tight-fitting garments that rub against the skin or retain moisture. Be sure to wear dry clothing or non-sweaty clothing to assist you in keeping the affected area dry and comfortable.

5. Is lichen sclerosus a sexually transmitted disease?

Lichen sclerosus is not sexually transmitted, and it does not spread among individuals. Although its appearance may resemble that of an STI (sexually transmitted infection), it is not contagious. One should avoid having sexual relations until they get a proper diagnosis from a medical expert.

Conclusion

Gaining a thorough knowledge of lichen sclerosus, including its causes, clinical features, diagnostic methods and available treatments, is vital for both academic learning and clinical practice. 

Early identification and proper management are key to reducing complications and improving patient outcomes, particularly in cases involving sensitive areas such as the genitals and perianal skin.
