What is the prevalence of Lichen Planus?

Lichen Planus is a relatively common chronic inflammatory skin condition that affects both men and women of all ages, although it is more prevalent in middle-aged adults. The exact prevalence of Lichen Planus is difficult to determine due to variations in reporting and diagnosis. However, it is estimated that the condition affects approximately 1-2% of the general population worldwide.

Lichen Planus can manifest in various forms, including skin lesions, oral involvement, genital involvement, and even nail abnormalities. The characteristic skin lesions are typically itchy, flat-topped, and shiny, often with a purplish color. Oral Lichen Planus presents as white, lacy patches or sores inside the mouth, while genital involvement may cause discomfort and erosions.

Although the exact cause of Lichen Planus is unknown, it is believed to involve an abnormal immune response. Certain factors, such as stress, certain medications, and viral infections, may trigger or exacerbate the condition. Lichen Planus is not contagious and cannot be spread from person to person.

While Lichen Planus can be bothersome and affect the quality of life, it is usually not a serious condition and tends to resolve on its own within months to years. However, in some cases, treatment may be necessary to alleviate symptoms and manage complications. If you suspect you have Lichen Planus, it is important to consult a dermatologist for an accurate diagnosis and appropriate management.
