18 Key Symptoms of Lichen Planus You Need to Recognize

17. Thickened Skin Patches

Lichen planus can cause areas of thickened skin, known as lichenified plaques, in cases where the rash is persistent or the patient scratches excessively. These plaques are often intensely itchy and may appear raised, darkened, or scaly. They typically develop on areas of the body subject to repeated friction or irritation, such as the wrists, ankles, or lower legs. Over time, the constant cycle of scratching and healing can worsen the plaques, making them more challenging to treat. Thickened skin patches can also leave behind areas of discoloration or scarring once the condition resolves. Treatment focuses on breaking the itch-scratch cycle through the use of corticosteroid creams, antihistamines, or moisturizers to soothe the skin. For particularly stubborn plaques, dermatologists may recommend more advanced treatments like phototherapy or injectable medications to reduce inflammation and encourage healing.
