What is a common symptom of contact dermatitis?

A common symptom of contact dermatitis is an itchy rash with vesicles. This condition typically arises as a reaction to allergens or irritants that come into contact with the skin. The vesicles, which are small fluid-filled blisters, can develop in response to the inflammation caused by this exposure. The presence of both itching and vesicles is characteristic of the body's localized immune response to the offending substance, making it a hallmark sign of contact dermatitis.

While dry, flaky skin, red scaly patches, and oozing sores can be symptoms associated with other skin conditions or complications, they do not specifically identify contact dermatitis in the same way an itchy rash with vesicles does. The vesicular aspect is particularly noteworthy since it distinguishes contact dermatitis from other dermatitis types, thereby pinpointing it as a key feature in diagnosis.
