What is lichen planus?

Lichen planus is a chronic inflammatory condition that can affect the skin, mouth, and genitals. It is characterized by itchy, flat-topped papules or plaques. The cause of lichen planus is unknown, but it is thought to be an autoimmune disorder.

Classification of lichen planus:

Lichen planus can be classified into two main types:

• Chronic lichen planus is the most common type and is characterized by persistent lesions that may last for months or years.
• Acute lichen planus is less common and is characterized by more severe lesions that usually resolve within a few weeks or months.

Symptoms:

The symptoms of lichen planus can vary depending on the type and location of the lesions.

Skin lesions of lichen planus are typically flat-topped, purple-red papules or plaques that may be itchy or painful. They may be found anywhere on the body, but they are most common on the arms, legs, torso, and scalp.

Mouth lesions of lichen planus are typically white, lacy patches that may be painful or itchy. They may be found on the tongue, gums, lips, or inside of the cheeks.

Genital lesions of lichen planus are typically red, itchy, or painful sores. They may be found on the penis, scrotum, vulva, or vagina.

The diagnosis of lichen planus is usually based on a physical examination and a biopsy of the affected skin.

Treatment of lichen planus:

There is no cure for lichen planus, but treatment can help to relieve symptoms and improve the appearance of the lesions. Treatment options include:

- Topical steroids:

Topical steroids are the most common treatment for lichen planus. They can be applied directly to the affected skin to reduce inflammation and itching.

- Oral steroids:

Oral steroids may be prescribed for severe cases of lichen planus.

- Phototherapy:

Phototherapy involves exposing the affected skin to ultraviolet light. It can be effective in treating lichen planus, but it can also cause side effects, such as skin irritation.

Lichen planus is a chronic condition, but it is usually not serious. With treatment, the symptoms can be controlled and the lesions can improve.
