Plaque Psoriasis is the most common variety of psoriasis. Patients with plaque-type psoriasis will have stable, slowly growing plaques, which remain unchanged for long periods of time.
Areas affected by Plaque Psoriasis
The most common areas for plaque psoriasis to occur are the elbows, knees, gluteal cleft, and the scalp. Involvement tends to be symmetric.
Inverse psoriasis affects the intertriginous regions including the axilla, groin, submammary region, and navel.
It also tends to affect the scalp, palms, and soles.
The individual lesions are sharply demarcated plaques but may be moist due to their location.
Symptoms of Plaque psoriasis
Skin affected with psoriasis is generally very dry, and other possible symptoms include skin pain, itching and cracking. They are covered by a flaky, silvery white buildup called "scale," which is composed of dead skin cells. This scale comes loose and sheds constantly from the plaque.
Plaque Psoriasis rarely remits spontaneously. It generally develops slowly and runs an indolent course.
