Allergic contact dermatitis (ACD) is a type of contact dermatitis that is caused due to an allergic response caused by contact. Failure to identify the allergy causing substance may lead to persistent ACD or relapse of the allergy. Initial symptoms of ACD are rash or skin lesion at the site of exposure. ACD is characterized by pruritic papules and vesicles on the erythematous base. Depending on the allergen type, rashes may ooze, crust or drain or become raw and scaled. Topical medications applied for leg ulcers may also cause ACD. The symptoms often last for one month before they are resolved completely.
