What is a common symptom of atopic dermatitis?

Intense itching is a hallmark symptom of atopic dermatitis, also known as eczema. This condition often leads to dry, inflamed skin that can be very uncomfortable and itchy. The itching associated with atopic dermatitis can be so severe that it may lead to scratching, which in turn can worsen the skin irritation and potentially lead to a secondary infection. This intense itching is a defining characteristic that sets atopic dermatitis apart from other skin conditions.

In contrast, ulceration of the skin is not directly associated with atopic dermatitis; it is more commonly seen in other conditions. Oily skin does not characterize atopic dermatitis; rather, individuals often have dryness. Hives, which are raised, itchy welts on the skin, are typically related to allergic reactions and are not a primary symptom of atopic dermatitis. Thus, intense itching clearly stands out as the correct answer for this question.
