Which condition is characterized by red, dry, elevated lesions covered by silvery scales?

• A. Dermatitis
• B. Eczema
• C. Psoriasis
• D. Acne

Answer: (C)

Psoriasis is a chronic autoimmune condition that is specifically characterized by red, dry, elevated lesions that are covered by silvery-white scales. These lesions often appear on the elbows, knees, scalp, and lower back, among other areas. The scales are a result of an accelerated skin cell production process, leading to a buildup of dead skin cells on the surface. This accumulation creates the signature plaques seen in psoriasis. The condition can vary in severity and may also be accompanied by joint pain or stiffness in a related condition known as psoriatic arthritis. Understanding that psoriasis is caused by an immune system malfunction helps distinguish it from other skin conditions.
