Which physical findings are typically seen in Psoriasis?

In psoriasis, the hallmark physical findings include pruritic erythematous plaques that are covered with silvery-white scales. These plaques can vary in size and are often found on the scalp, elbows, knees, and lower back, but they can occur anywhere on the body. The crusty appearance of the scales is due to accumulation of dead skin cells, and the inflammation leads to the characteristic redness in the affected areas, which can be itchy or uncomfortable for the patient.

The presence of these specific plaques distinguishes psoriasis from other conditions such as eczema or fungal infections. Understanding the unique presentations allows for a more accurate diagnosis and appropriate treatment plan for patients experiencing this chronic inflammatory skin disorder.
