What is the term for a noninfectious, inflammatory skin disease characterized by redness, blisters, scabs, and itching?

The term for a noninfectious, inflammatory skin disease that is characterized by redness, blisters, scabs, and itching is eczema. This condition is known for causing the skin to become inflamed, leading to symptoms such as intense itching and discomfort. The blisters that may form can weep and become crusty, often resulting in scabs as they heal. Eczema is particularly common in children, but it can affect individuals of all ages and can be triggered by various factors, including allergens, irritants, and stress.

While other conditions like psoriasis, rosacea, and dermatitis have overlapping symptoms, they differ in their specifics. Psoriasis, for instance, is characterized by thick, silvery scales along with red patches, and is often chronic. Rosacea is primarily marked by facial redness, visible blood vessels, and could involve pustules, but does not typically present with scabs in the same way. Dermatitis is a broader term that encompasses various types of skin inflammation, including eczema but does not specifically define the characteristic symptoms described in the question. Thus, eczema stands out as the correct term for this particular presentation.
