Atopic dermatitis is a chronic inflammatory skin disease associated with cutaneous hyper-reactivity to environmental triggers that are generally innocuous to healthy, nonatopic individuals (Leung et al. 2004). Acute eczematous skin lesions in atopic dermatitis are characterized by marked epidermal intercellular edema (spongiosis). Chronic lesions are characterized by an acanthotic epidermis with elongation of the rete ridges, parakeratosis, and minimal spongiosis (Leung and Bieber 2003).
