Perform a routine skin examination to look for features associated with atopic dermatitis. In younger patients, examine for dermatographism, as many patients may have acute urticaria in the setting of atopic dermatitis.

Essential features (must be present) include the following:

  • Pruritus

  • Eczema (acute, subacute, chronic): (1) Typical morphology and age-specific patterns (facial/neck/extensor involvement in children, flexural involvement in any age group, sparing the groin and axillary regions); (2) chronic or relapsing history

Important features (supports the diagnosis) include the following:

  • Early age of onset

  • Atopy: (1) Personal and/or family history; (2) IgE reactivity

  • Xerosis

Associated features (nonspecific but suggest the diagnosis) include the following:

  • Atypical vascular responses (eg, facial pallor, delayed blanch response)

  • Keratosis pilaris/pityriasis alba/hyperlinear palms/ichthyosis

  • Ocular/periorbital changes

  • Other regional findings (eg, perioral changes/periauricular lesions)

  • Perifollicular accentuation/lichenification/prurigo
