Plaque psoriasis, often called psoriasis vulgaris, is the most common type of psoriasis, affecting about 80% of those with the condition. While the exact cause remains uncertain, certain risk factors increase the likelihood of development. Variations of plaque psoriasis exist, and although it cannot be completely cured, effective management strategies can help control symptoms and improve quality of life.

Signs and Symptoms
The primary feature is thick, dry, raised skin patches covered with a silvery-white scale, known as plaques. These patches are often itchy and vary in appearance depending on the subtype, location, and severity.

Common signs include dryness, redness, and intense itching. The manifestation of plaques varies by type, and factors like location and severity influence their appearance.

Types of Plaque Psoriasis

Small Plaque Psoriasis
This form presents as tiny, pink lesions that may stay separate or merge over time. The surface is flaky and crusty. It often responds well to light therapy and usually affects individuals over 40, but can occur at any age.

Large Plaque Psoriasis
Characterized by bigger, clearly defined red patches with silvery scales. It often starts before age 40 and may have a genetic component, commonly linked to metabolic issues like high cholesterol or blood sugar. It tends to be more resistant to treatment.

Unstable Plaque Psoriasis
Lesions may enlarge, lose shape, and merge into larger patches. New plaques can develop, indicating active disease. Treatment focuses on controlling progression.

Stable (Chronic) Plaque Psoriasis
This persistent form shows recurring plaques, especially on knees, elbows, scalp, and torso, often appearing symmetrically and recurrently over time.

Psoriasis of the Scalp

Red, thick, itchy patches are typical.

Scaly layers resembling dandruff with silvery-white flakes.

The scalp may become dry, cracked, and prone to bleeding.

Temporary hair thinning, burning, or soreness are common symptoms.

Psoriasis can also affect facial skin, causing redness, dryness, and scales around areas like the forehead, eyes, cheeks, or chin. Skin around the nose, mouth, and eyebrows may also be involved. Consulting a dermatologist for proper diagnosis and treatment is recommended for any noticeable skin changes.

Care and Treatment Tips

Although a complete cure isn't available, treatments aim to reduce flare-ups and minimize triggers. Common strategies include:

Topical Medications: Corticosteroid creams and ointments applied after bathing help reduce inflammation and slow skin cell proliferation, providing symptom relief.

Phototherapy: Controlled ultraviolet light therapy effectively treats widespread psoriasis, though direct sun exposure is discouraged due to skin cancer risks. Medical supervision is essential.
