Introduction to Plaque Psoriasis
Plaque psoriasis is the most common form of psoriasis. It affects approximately 80-90% of people with psoriasis. The exact cause of plaque psoriasis is not fully understood, but it is believed to be related to the immune system. Genetic factors and environmental triggers may also play a role in the development of plaque psoriasis.
Symptoms of Plaque Psoriasis
The primary symptom of plaque psoriasis is the presence of red, raised patches on the skin. These patches are covered with a silvery-white scale, which may come off in flakes. The plaques can be itchy, painful, or both. Plaque psoriasis commonly affects areas such as the elbows, knees, scalp, and lower back.
Appearance of Plaque Psoriasis
Plaque psoriasis presents as well-defined, red patches on the skin. The patches are typically covered with thick, silvery-white scales. The skin around the plaques may appear inflamed and irritated. Plaque psoriasis lesions can range in size from small to large, and they may merge together to form larger plaques.
Diagnosing Plaque Psoriasis
Diagnosing plaque psoriasis usually involves a physical examination of the skin by a dermatologist. The dermatologist may also ask about the patient's medical history and any family history of skin conditions. In some cases, a skin biopsy may be necessary to confirm the diagnosis of plaque psoriasis.
Treatment of Plaque Psoriasis
There is no cure for plaque psoriasis, but various treatments can help manage the symptoms and reduce the severity of flare-ups. Treatment options may include topical medications, phototherapy, oral medications, and biologic therapies. Individualized treatment plans are often developed based on the patient's overall health, the extent of their psoriasis, and their treatment preferences.
