Symptoms of Plaque Psoriasis
The hallmark symptom of plaque psoriasis is the presence of raised, red patches of skin with silver-white scales. These patches, also known as plaques, can appear anywhere on the body but are most commonly found on the elbows, knees, scalp, and lower back. The skin around the patches may be red and inflamed, and the affected areas can be itchy and painful. Plaque psoriasis can also lead to nail changes, such as pitting, discoloration, and thickening of the nails.
Appearance of Plaque Psoriasis
The appearance of plaque psoriasis can vary depending on the individual and the severity of the condition. In some cases, the plaques may be small and localized, while in others, they can be larger and more widespread. The scales on the patches can be thick and silvery-white, giving the skin a scaly appearance. The redness of the patches is caused by inflammation and increased blood flow to the affected area.
Diagnosis and Treatment
Diagnosing plaque psoriasis typically involves a physical examination of the skin and a review of the patient's medical history. In some cases, a skin biopsy may be necessary to confirm the diagnosis. Treatment options for plaque psoriasis include topical creams, phototherapy, oral medications, and in severe cases, biologic therapies. Managing plaque psoriasis often requires a combination of treatment modalities tailored to the individual patient.
