Acute AD lesions are characterized by intense pruritus, erythematous papules, and excoriations with a serous exudate, whereas chronic lesions consist of nonerythematous thickened plaques of skin with accentuated skin markings (lichenification). Fibrotic papules (prurigo nodularis) may be present in long-standing chronic Atopic Dermatitis lesions. Some symptons of Atopic Dermatitis :
Evaluation of Severe Atopic Dermatitis
The grading of the severity of Atopic Dermatitis is based on the extent of affected areas, itch intensity, and appearance of the skin lesions. In general, patients with more than 20% skin involvement (or 10% skin involvement if affected areas include the eyelids, hands, or intertriginous areas) who have not responded to first-line treatment (see section on Management may be considered to have severe AD . Factors that contribute to severity of AD include the following:
