    Glossary Lichen Planus Pigmentosus

    chronic skin condition with dark, flat patches

    Lichen Planus Pigmentosus (LPP) is a chronic skin condition characterized by dark, flat patches on the skin, often appearing on sun-exposed areas and flexural regions like the armpits and groin. It is a variant of lichen planus, and while the exact cause is unknown, it is believed to be an autoimmune response where the body's immune system mistakenly attacks its own skin cells.
