Lichen Planus
Lichen Planus is a chronic inflammatory disease affecting the skin, hair, nails, and mucous membranes. The disease is characterized by purplish, flat-topped, itchy lesions on the skin, which may develop into blisters and ulcers. The exact cause of Lichen Planus is unknown, but it is often triggered by an allergic or immune reaction. The condition can affect anyone, but it is more common in middle-aged adults. Diagnosis is based on visual examination, and sometimes a biopsy may be necessary. Treatment may include topical or oral medications or light therapy. Lichen Planus is not contagious, and it cannot be cured, but it can be managed effectively, and most cases resolve within several months to two years. It is important to follow the treatment plan and see a dermatologist regularly.
Symptoms of Lichen Planus
What are the typical symptoms of Lichen Planus?
Lichen planus is typically characterized by itchy purple or white bumps that appear on the skin or mucous membranes. Other symptoms may include rough patches on the skin, painful ulcers in the mouth or genitals, and changes in nail appearance.
Can stress be a cause of Lichen Planus?
While stress can weaken the immune system, there is no substantial evidence linking stress as a direct cause of lichen planus. However, stress can worsen symptoms and trigger outbreaks in some individuals.
How does Lichen Planus cause skin blistering?
Lichen planus causes skin blistering through a process called apoptosis, which is the natural programmed cell death of skin cells. In lichen planus, T cells in the immune system identify healthy skin cells as foreign and attack them, causing an inflammatory response that leads to blistering.
Are there any genetic factors associated with Lichen Planus?
Although there is no clear genetic link to lichen planus, studies have found that certain genetic variations may increase an individual`s susceptibility to the disorder. This suggests that genetic factors may play a role in the development and severity of lichen planus.
What triggers Lichen Planus outbreaks?
The exact triggers of lichen planus outbreaks are not yet fully understood. However, some factors that may contribute to outbreaks include viral infections, stress, allergic reactions, exposure to certain chemicals, and certain medications. It is important to note that triggers can vary among individuals and more research is needed to fully understand the underlying causes of lichen planus.
Diagnosis of Lichen Planus

Other symptoms may include itching, burning, and soreness. Source: American Academy of Dermatology (https://www.aad.org/public/diseases/rashes/lichen-planus#symptoms)
Treatments of Lichen Planus
What are the most common medications used for managing Lichen Planus?
The most common medications for managing Lichen Planus include topical and oral corticosteroids, such as clobetasol, betamethasone, prednisolone, and dexamethasone. Immune-modulating drugs like tacrolimus and cyclosporine can also be used in severe and resistant cases. In addition, antihistamines, antibiotics, and antifungal drugs may be prescribed based on individual symptoms and presentation.
How effective is phototherapy in treating Lichen Planus?
Phototherapy, also known as light therapy, has shown promising results in treating Lichen Planus. Narrowband ultraviolet B (NB-UVB) and psoralen with ultraviolet A (PUVA) are the most commonly used light therapies for Lichen Planus. Studies have reported an improvement in symptoms in up to 80% of treated patients. However, it is important to note that long-term effects and success rates may vary among different individuals.
What dietary changes may help alleviate symptoms of Lichen Planus?
Dietary changes may not directly alleviate symptoms of Lichen Planus, but avoiding certain triggers like spicy or acidic foods, alcohol, caffeine, and tobacco may help reduce inflammation and irritation. A balanced diet rich in fruits, vegetables, and whole grains may also boost overall immunity and promote healing. It is advisable to consult a qualified physician or dietitian before making any significant dietary changes.
Can topical corticosteroids provide long-term relief for Lichen Planus?
Topical corticosteroids can provide short-term and, in some cases, long-term relief for Lichen Planus. However, prolonged use of these medications can cause thinning of the skin, skin discoloration, and other adverse effects. Therefore, it is important to follow a prescribed regimen as per the physician`s instructions and monitor for any side effects.
Are there any alternative therapies that can effectively treat Lichen Planus?
While conventional treatments are often effective in managing Lichen Planus, some alternative therapies may also offer relief.
