What it is
Skin lichen planus often clears up within a year or two. Mouth lichen planus can last longer.
Steroid creams, mouthwashes and other treatments help with symptoms. Mouth lichen planus needs regular check-ups, as there is a small increased risk of mouth cancer.
Common signs
- Shiny, purple-red, flat-topped bumps on the skin

Questions to ask your doctor
- How long might it last?
