How are lesions typically presented in contact dermatitis?

In contact dermatitis, lesions are typically characterized by being vesicular, which means they may present as small, fluid-filled blisters. These vesicles can become crusted, especially if they are scratched or if secondary infections occur. Pruritus, or itching, is a hallmark symptom associated with contact dermatitis due to the inflammatory response elicited by the offending substance. The combination of these features makes the presentation of lesions in contact dermatitis unique and recognizable.

Understanding this characteristic presentation helps healthcare providers diagnose and manage contact dermatitis effectively, distinguishing it from other dermatological conditions that may have different lesion characteristics. For example, the other options do not fully capture the typical vesicular nature and associated itching of contact dermatitis lesions, which are essential components of its clinical presentation.
