### What is Plaque Psoriasis? Plaque psoriasis is the most common type of psoriasis, a chronic skin condition that causes itchy and painful rashes. It appears as raised red or purple patches covered with a whitish buildup of dead skin cells, known as plaques. These plaques typically show up on your elbows, knees, scalp, and back, but they can appear anywhere on your body. ### Symptoms - **Plaques:** Raised red, brown, purple, or gray patches covered with a white or silvery layer. - **Itchiness and Pain:** The plaques can be itchy and painful. - **Symmetry:** Plaques often appear on both sides of your body, like both elbows or both knees. ### Causes Plaque psoriasis is an autoimmune disease, meaning your immune system mistakenly attacks healthy cells. This causes new skin cells to grow much faster than normal, leading to the buildup of plaques. Genetics and health history play a role, and common triggers include stress, smoking, and infections. ### Diagnosis A dermatologist can usually diagnose plaque psoriasis by examining your skin and discussing your medical history. In some cases, a biopsy or additional tests may be needed to rule out other conditions. ### Treatment Options - **Topical Medications:** Creams and ointments like corticosteroids and anthralin can help reduce inflammation and slow skin cell growth. - **Light Therapy:** Ultraviolet light treatment can be effective for widespread rashes. - **Systemic Medications:** Pills or injections that affect your entire body, such as methotrexate or biologic drugs, can help calm your immune system. ### Self-Care Tips - **Moisturize:** Use a good moisturizer to keep your skin soft and reduce itchiness. - **Avoid Triggers:** Identify and avoid triggers like stress and certain foods. - **Stay Hydrated:** Drink plenty of water to keep your skin moist. - **Support:** Seek emotional support if needed, as the condition can take an emotional toll. ### Conclusion Plaque psoriasis is a long-lasting condition that can cause significant discomfort. While there's no cure, various treatments can help manage symptoms. Regular consultations with your doctor are essential to find the best treatment plan for you.
