About Lichen Planus
Lichen planus is an inflammatory disease that affects the skin and mucous membranes. Lichen planus is believed to be an autoimmune disorder, where the immune system mistakenly attacks healthy tissues. It starts with an autoimmune response mediated by T lymphocytes, causing inflammation and alterations in the basal cells of the epithelium. This leads to an inflammatory infiltrate in the basement membrane and subsequent complications.
Non-modifiable risk factors are risk factors that cannot be changed. Non-modifiable risk factors for lichen planus:
- Genetics: Certain genetic factors may make some individuals more susceptible to developing lichen planus. It can run in families.
- Age and sex: Lichen Planus is more common in middle-aged individuals, and females are more likely to develop the oral form of the condition.
Modifiable risk factors are risk factors that can be changed or influenced. Modifiable risk factors for lichen planus:
- Viral infection: Lichen lanus can be triggered by viral infections, such as hepatitis C or certain types of herpes viruses.
- Environmental factors: Exposure to certain substances like metal dental fillings and some medications may contribute to the development of Lichen Planus.
It's important to note that while these factors may increase the risk of developing Lichen Planus, they do not guarantee its occurrence. If you have concerns about your risk or symptoms, it's best to consult with a healthcare professional for proper evaluation and guidance.
The most common early symptoms of lichen planus include:
- Purplish, flat-topped bumps on the skin
- Itchiness at the site of the rash
- Fluid-filled blisters that burst and scab over
- Lacy-white lesions which may be painful or cause a burning sensation
As lichen planus progresses or becomes more severe, other common symptoms may occur, such as:
- Open sores (ulceration) in the mouth
- Tender, swollen patches that are bright red in the mouth
- Pain or discomfort when speaking, eating, or drinking
- Increased sensitivity to acidic, spicy, coarsely textured, or hot foods
- Inflammation of the gums, including bleeding when brushing your teeth
It's important to note that not everyone will experience all of these symptoms, and the severity of symptoms can vary from person to person. If you suspect you have lichen planus or are experiencing any concerning symptoms, it's best to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.
To diagnose lichen planus, health care providers may perform the following examinations, tests, and procedures:
- Physical exam: The health care provider will conduct a thorough physical exam to look for physical signs of lichen planus, such as skin lesions or oral ulcers.
- Medical history: Gathering information about your medical history, including any previous diagnoses, can help in the diagnosis of lichen planus.
- Lab tests: Specific lab tests, such as a blood draw, may be recommended to rule out other conditions or to confirm the diagnosis of lichen planus.
- Biopsy: A small sample of affected tissue may be taken for examination under a microscope to confirm the diagnosis and assess the severity of lichen planus.
- Patch testing: Patch testing involves applying small amounts of potential allergens on your skin to identify any allergic reactions that may contribute to the development or worsening of lichen planus.
It's important to note that the specific examinations, tests, and procedures recommended may vary depending on individual circumstances. Consult with your health care provider for personalized advice.
The goals of treatment for lichen planus are to manage symptoms, minimize lesions, and improve the patient's quality of life. Here are some recommended treatments and how they work to achieve these goals:
Medications:
- Topical corticosteroids: These medications, such as triamcinolone acetonide, fluocinolone acetonide, betamethasone dipropionate, and clobetasol propionate, are applied directly to the affected area. They help reduce inflammation and itching.
- Systemic corticosteroids: If topical corticosteroids are not effective, oral or injectable corticosteroids may be prescribed to control symptoms.
- Topical calcineurin inhibitors: These medications, such as pimecrolimus or tacrolimus, help suppress the immune response in the affected area.
Therapies:
- Broadband or narrowband UV therapy: This involves exposing the affected skin to ultraviolet light, which can help reduce inflammation and improve symptoms.
- Combination therapy with UV and acitretin: Acitretin is a medication that helps regulate the growth of skin cells and can be used in combination with UV therapy.
Self-care and health behavior changes:
- Using mild toothpaste and practicing good oral hygiene.
- Eating a well-balanced diet rich in fruits, vegetables, nuts, and lean protein.
- Getting regular exercise.
- Reducing stress levels.
It's important to note that treatment for Lichen Planus should be individualized based on the severity of symptoms and the patient's response to different treatments. Always consult with a healthcare professional for personalized advice.
