What distinguishes eczema from psoriasis in skin appearance?

Eczema is characterized by red, dry, and itchy lesions, which is a hallmark of this condition. It often involves inflammation of the skin, leading to dryness, redness, and the intense itch that commonly accompanies it. The lesions can vary in appearance, often presenting as patches that may ooze or crust when scratched. The itchiness and dry nature of eczema lesions play a significant role in the patient's experience of the disease, making it a primary differentiating factor from psoriasis.

In contrast, psoriasis typically presents with thick, silvery scales and is known for its well-defined plaques that can be red and inflamed. These plaques are usually covered with a silvery-white scale and might have an appearance that is markedly different from eczema’s lesions. The distinction between these two conditions is key, as their management can differ considerably. The presentation of psoriasis involving dimpled centers is a more specific characteristic called "Auspitz sign," which might also help in distinguishing it from eczema.
