What is the difference between lichen sclerosus and lichen planus?
Lichen sclerosus and lichen planus are both chronic skin conditions, but they differ in appearance, location, symptoms, and potential complications. Specialist assessment is needed for accurate diagnosis.
Detailed Medical Explanation
Lichen sclerosus mainly affects the vulval and anal skin with white, thin, shiny patches that may scar. Lichen planus can involve skin, mouth, and genital mucosa, and is often purple, flat-topped, and itchy, sometimes causing erosions and painful raw areas. Lichen planus can also cause scarring and adhesions but may be more likely to affect vaginal and oral mucosa. Both require biopsy if the diagnosis is unclear. For further guidance see NHS on lichen sclerosus and NHS on lichen planus.
