Understanding Plaque Psoriasis
Plaque psoriasis is the most common form of psoriasis, affecting millions of people worldwide. It is characterized by raised, red patches covered with a silvery white buildup of dead skin cells. These patches, known as plaques, can appear anywhere on the body but are commonly found on the elbows, knees, scalp, and lower back. Plaque psoriasis is not contagious but is believed to be caused by an overactive immune system triggering excessive skin cell growth.
Symptoms of Plaque Psoriasis
The primary symptom of plaque psoriasis is the presence of raised, inflamed patches of skin covered with silvery scales. These patches can be itchy and painful, causing discomfort to the affected individual. Other common symptoms include dry, cracked skin that may bleed, and thickened, pitted, or ridged nails. Plaque psoriasis can also lead to joint pain and swelling in some cases, a condition known as psoriatic arthritis.
Distinguishing Plaque Psoriasis from Other Skin Conditions
Psoriasis can be mistaken for other skin conditions such as eczema, dermatitis, or fungal infections. However, plaque psoriasis has distinct characteristics that differentiate it from these conditions. Unlike eczema, psoriasis plaques are usually thicker and have a silvery sheen. Furthermore, plaque psoriasis often develops symmetrically on both sides of the body, whereas other skin conditions may not.
