What is the prognosis of lichen planus?

Lichen planus typically has a good prognosis. The majority of cases resolve spontaneously within 6 to 12 months, although some may persist for longer. Treatment can help to relieve symptoms and speed up the healing process.

In some cases, lichen planus can lead to complications, such as:

* Scarring: Lichen planus can cause scarring, especially if the lesions are severe or long-lasting.

* Infection: Lichen planus can increase the risk of infection, especially if the lesions are broken or scratched.

* Oral lichen planus: Oral lichen planus can lead to pain, difficulty eating, and changes in taste.

* Lichen planus pigmentosus: Lichen planus pigmentosus is a rare form of lichen planus that causes dark, pigmented patches on the skin.

* Lichen planus follicularis: Lichen planus follicularis is a rare form of lichen planus that affects the hair follicles, causing hair loss.

Overall, the prognosis of lichen planus is good. Most cases resolve spontaneously within a year, and treatment can help to relieve symptoms and speed up the healing process. However, some cases may lead to complications, such as scarring, infection, or oral lichen planus.
