In short
Lichen planus is an immune-related condition that can affect the skin, the inside of the mouth, the scalp, nails and genitals. On skin it causes itchy, flat-topped purple or dark bumps, often on the wrists and ankles, and in the mouth it can cause lacy white patches or sores. A pigmented form that causes dark patches on the face and neck is fairly common in India.
Typical signs
- Itchy, shiny, flat-topped purple or dark bumps
- Bumps on the wrists, ankles, shins or lower back
- Lacy white lines or sore patches inside the cheeks

When to see a dermatologist
