Lichen ruber planus, also known as lichen planus, is a chronic inflammatory skin disorder characterized by the presence of itchy, flat-topped, polygonal-shaped, purple or reddish-colored bumps or plaques on the skin or mucous membranes. Lichen ruber planus can affect various areas of the body, such as the skin, mouth, genitals, nails, and scalp.
The exact cause of lichen ruber planus is unknown, but it is believed to be an autoimmune condition, meaning that the body's immune system mistakenly attacks its own healthy tissues, leading to the characteristic skin lesions. It may also be triggered by certain medications, infections, or allergens.
Symptoms of lichen ruber planus include the presence of multiple itchy, flat-topped, shiny, or scaly bumps or plaques on the skin. These lesions often appear symmetrically and may develop a network-like pattern when they join together. In oral lichen planus, the lesions appear as white, lacy patches in the mouth. In severe cases, lichen ruber planus can cause nail abnormalities or hair loss.
Treatment for lichen ruber planus aims to relieve symptoms and reduce inflammation. This can be achieved through the use of topical corticosteroids, immune-modulating drugs, antihistamines, or other medications. In some cases, phototherapy or oral medications may be necessary. Regular monitoring and follow-up with a dermatologist or healthcare provider are important for managing the condition effectively.
While lichen ruber planus cannot be cured, with appropriate treatment and management, most cases can be controlled, and symptoms can be improved or resolved.
