title: Poison ivy dermatitis.
abstract: Eruptions caused by poison ivy (see Cover) and related plants are almost always a form of allergic contact dermatitis. Usually they can be readily recognized because of their characteristic streak- or line-like appearance. They usually clear within one to three weeks unless there is continued exposure to the allergen. Local treatment suffices in mild to moderate cases, but in more severe cases systemic corticosteroids can be added.
