What skin condition is characterized by overly dry or itchy skin?

The condition described in the question is properly matched to dermatitis. Dermatitis refers to inflammation of the skin, which often leads to symptoms such as dryness, redness, itching, and irritation. This condition can result from a variety of irritants or allergens, and it often affects the skin’s ability to retain moisture, thereby causing it to become overly dry and itchy.

In contrast, senile purpura, which is associated with aging, manifests as purple bruises due to fragile blood vessels but does not primarily involve dry or itchy skin. Pressure ulcers, also known as bedsores, occur when there is prolonged pressure on the skin, typically leading to open sores rather than dryness. Skin tags are benign growths that don’t usually cause itchy or dry skin; they appear as small, soft pieces of skin that hang off the body. Understanding these distinctions helps clarify why dermatitis is the correct answer when considering symptoms of dry or itchy skin.
