Lichen Planus-Dr-Colin-Hong

Lichen planus is a skin condition that affects millions of people worldwide. It is a chronic, inflammatory disorder that can cause itching, rash, and discoloration of the skin, nails, and mucous membranes. This condition can be distressing, as it can impact the appearance and function of affected areas. While the exact cause of lichen planus is still unknown, research suggests that it may be related to an abnormal immune response or a viral infection. Despite its prevalence, lichen planus is often misdiagnosed or underdiagnosed, leading to delayed treatment and worsening symptoms. 

Here, we will explore the causes, symptoms, and treatment options available for lichen planus, as well as tips for managing the condition and improving overall skin health.

History and Definition

Lichen planus is a chronic, inflammatory skin condition that was first described by Erasmus Wilson, a British dermatologist, in 1869. The name “lichen planus” was coined by the German dermatologist, Wilhelm von Bärensprung, in 1828, who noted that the skin lesions resembled those of lichens, a type of symbiotic organism consisting of a fungus and algae or cyanobacteria.

Lichen planus is characterized by small, itchy, flat-topped, polygonal bumps that typically occur on the inner wrist, ankles, and lower legs. These bumps can also appear on the mucous membranes of the mouth, throat, and genitals, causing discomfort and pain.

Lichen planus can affect people of all ages and genders, but it is more common in middle-aged adults. It is not contagious, and it typically does not pose a serious health risk. However, the condition can be distressing and can impact the quality of life of those affected.

There are several types of lichen planus, including the classic form, hypertrophic lichen planus, erosive lichen planus, and bullous lichen planus. The severity and duration of the condition can vary, and it may take several months or even years for the symptoms to resolve.


Lichen planus is a skin condition that can cause a variety of symptoms, depending on the type and location of the lesions. Some of the most common symptoms of lichen planus include:

  • Skin Lesions: The classic form of lichen planus is characterized by small, flat-topped, polygonal bumps that are often purple, red, or brown in color. These bumps can appear on the wrists, ankles, lower legs, and other parts of the body, and they may be itchy or painful.


  • Mucous Membrane Lesions: In some cases, lichen planus can also affect the mucous membranes of the mouth, throat, and genitals, causing white, lacy patches, redness, and painful sores.


  • Nail Changes: Lichen planus can cause changes in the appearance and texture of the nails, including thinning, ridging, and splitting.


  • Hair Loss: In rare cases, lichen planus can cause hair loss or scarring of the scalp.


  • Itching: Lichen planus lesions may be accompanied by itching or burning sensations, which can be particularly bothersome at night.


  • Pain: Lesions on the mucous membranes can be painful and make it difficult to eat, drink, or speak.

It is important to note that not everyone with lichen planus will experience all of these symptoms, and the severity of the symptoms can vary from person to person. If you are experiencing any of these symptoms, it is important to consult with a healthcare professional for an accurate diagnosis and treatment plan.


The exact cause of lichen planus is not fully understood, but it is believed to be an autoimmune disorder, which means that the body’s immune system mistakenly attacks its own tissues.

Lichen planus is not contagious and cannot be spread from person to person. If you suspect you have lichen planus or have any concerns about your skin or mucous membranes, it is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment.


The diagnosis of lichen planus is usually made based on the characteristic appearance of the affected skin or mucous membranes. The healthcare provider will typically perform a physical exam and take a medical history to rule out other possible conditions with similar symptoms. In some cases, a skin biopsy may be necessary to confirm the diagnosis.

Often lichen planus resembles other skin conditions, such as eczema, psoriasis, or fungal infections, so a doctor’s evaluation is necessary for accurate diagnosis and treatment.


The treatment of lichen planus depends on the severity of the symptoms, the location of the lesions, and the patient’s overall health. In general, the goal of treatment is to reduce inflammation, alleviate symptoms, and promote healing. Both non-surgical and surgical treatment options are available for lichen planus.


  • Topical corticosteroids: These medications can help reduce inflammation and itching, and may be applied directly to the affected skin or mucous membranes.


  • Oral corticosteroids: In more severe cases, oral corticosteroids may be prescribed to help control symptoms.


  • Immunosuppressant medications: These medications may be used to help reduce the activity of the immune system and prevent further damage to the affected tissues.


  • Topical calcineurin inhibitors: These medications, such as tacrolimus and pimecrolimus, may be used to reduce inflammation and itching in sensitive areas, such as the face, groin, or anus.


  • Phototherapy: This treatment involves exposing the affected skin to ultraviolet light, which can help reduce inflammation and promote healing.


In some cases, surgical treatments may be necessary for lichen planus. For example, if the lesions are affecting the nails or scalp, surgical removal of the affected tissue may be necessary to promote healing.

With proper treatment, most people with lichen planus can expect their symptoms to improve over time. However, it is important to continue monitoring the affected areas for any signs of recurrence or complications and to follow up with a healthcare professional as needed. Some potential complications of lichen planus may include scarring, hyperpigmentation, or secondary infections.

Risk Factors

Certain risk factors have been identified that may increase the likelihood of developing the condition. Here are some of the most common risk factors for lichen planus:

  • Age: Lichen planus can occur at any age, but it is most common in middle-aged adults.


  • Gender: Lichen planus is more common in women than men.


  • Genetics: There is some evidence to suggest that lichen planus may run in families, suggesting a genetic component to the condition.


  • Autoimmune disorders: Lichen planus may be associated with other autoimmune disorders, such as lupus, rheumatoid arthritis, and celiac disease.


  • Hepatitis C infection: People with hepatitis C are more likely to develop lichen planus than those without the infection.


  • Certain medications: Some medications, including beta-blockers, nonsteroidal anti-inflammatory drugs (NSAIDs), and certain antibiotics, have been linked to the development of lichen planus.


  • Emotional stress: Emotional stress may trigger the onset or exacerbation of lichen planus in some people.

Having one or more of these risk factors does not necessarily mean that a person will develop lichen planus. Many people with the condition have no identifiable risk factors.


Lichen planus is generally a benign condition that does not cause serious health problems. However, in some cases, complications may arise. Here are some of the possible complications of lichen planus:

  • Scarring: In some cases, lichen planus lesions may heal with scarring, particularly on the skin and in the mouth.


  • Hyperpigmentation: After the lesions of lichen planus heal, they may leave behind brown or gray spots on the skin or mucous membranes.


  • Nail damage: Lichen planus can cause the nails to become thin, ridged, or brittle, and in severe cases, the nails may be lost altogether.


  • Oral cancer: There is a small risk of developing oral cancer in people with lichen planus affecting the mucous membranes of the mouth.


  • Vision loss: In rare cases, lichen planus can cause inflammation of the eyes, leading to vision loss.

  • Psychosocial effects: Lichen planus can be unsightly and uncomfortable, which may cause emotional distress or affect a person’s quality of life.

These complications are relatively rare and most people with lichen planus do not experience them. However, it is still important to seek medical attention if you suspect you may have lichen planus or if you experience any of these complications.

When to See a Doctor

If you suspect that you may have lichen planus, it is important to see a doctor for diagnosis and treatment. Here are some specific situations in which you should see a doctor for lichen planus:

  • Appearance of lesions: If you notice red or purple bumps, patches, or blisters on your skin, nails, or mucous membranes that persist for more than a few days or become painful or itchy, you should see a doctor.


  • Changes in the mouth: If you experience discomfort, pain, or open sores in your mouth, or if you have difficulty eating or speaking, you should see a dentist or doctor who specializes in oral health.


  • Difficulty breathing or swallowing: If you experience difficulty breathing or swallowing, seek immediate medical attention, as this may indicate a severe case of lichen planus affecting the airway.


  • History of autoimmune disease: If you have a history of autoimmune disease or take medications that suppress your immune system, you may be at greater risk for lichen planus and should see a doctor if you experience any of the symptoms.


  • Emotional distress: If your lichen planus is causing emotional distress or affecting your quality of life, you should see a doctor or mental health professional for support and guidance.

Remember, early diagnosis and treatment of lichen planus can help to alleviate symptoms and prevent complications, so don’t hesitate to seek medical attention if you suspect you may have this condition.

If you suspect you may have lichen planus, schedule an appointment with your primary care physician, a dermatologist, or a dentist if it is affecting your oral health.

During the consultation, the doctor will examine the affected areas of your skin, nails, or mucous membranes to make a diagnosis of lichen planus. In some cases, a skin biopsy may be necessary to confirm the diagnosis.

Treatment Plan

Treatment for lichen planus typically depends on the severity and location of the lesions. Topical corticosteroid creams or ointments may be prescribed to relieve itching and inflammation on the skin or scalp. For lichen planus in the mouth or genital area, topical corticosteroid gels or ointments may be prescribed, or oral medications such as corticosteroids, antihistamines, or immunosuppressants may be recommended.

In severe cases, light therapy or systemic corticosteroids may be used to treat lichen planus. Treatment may need to be continued for several weeks or months to achieve optimal results.

After Treatment

After treatment, it is important to continue following the doctor’s instructions and attend any follow-up appointments. If you experience any new or recurring symptoms, notify your doctor immediately. If the lichen planus was caused by a medication, avoiding the medication may be necessary to prevent a recurrence.

Regular self-examination and dental checkups are important to monitor for any changes in the condition. Avoiding triggers such as stress, injury, or certain foods may help prevent lichen planus from recurring.

Remember, treatment for lichen planus is individualized based on the severity and location of the lesions, so your doctor may recommend different treatment options depending on your specific case. Be sure to follow your doctor’s instructions and attend all follow-up appointments to ensure the best possible outcome.


In conclusion, lichen planus is a skin condition that can cause discomfort and distress. It often presents as an itchy, bumpy rash on the skin and mucous membranes. Treatment for lichen planus includes topical creams and ointments, oral medications, light therapy, and in some cases, surgery. While there is no definitive cure for lichen planus, its symptoms can be managed with proper care and medical treatment. 

As with any medical condition, it’s important to consult your doctor if you believe you may have developed lichen planus. With the right combination of treatment options and lifestyle changes, people living with this condition can continue to lead healthy lives free from pain or discomfort caused by their symptoms.
