Activity Description

Allergic contact dermatitis (ACD) is a type 4 or delayed-type hypersensitivity response (DTH) by an individual’s immune system to a small molecule (less than 500 daltons), or hapten, that contacts a sensitized individual’s skin. ACD accounts for 20% of contact dermatoses, and allergens differ greatly based upon geography, personal habits, and hobbies, and often, the types of preservatives that are legally permissible. This activity illustrates the etiology, pathophysiology, and highlights the role of the interprofessional team in the management of allergic contact dermatitis.
