Description

• Atopic Dermatitis is a common chronic or relapsing dermatitis characterized by severe pruritis, occurring primarily in infants and children. The age of onset is between 2 and 6 months in the majority of cases, but it may start at any age, even before the age of 2 months in some cases
• Although it often improves during adolescence, it may also become a chronic condition that extends into adulthood. Atopic dermatitis is often associated with atopic diseases such as asthma or allergic rhinitis 

Types

• The main symptom is intense pruritis and dry skin
• Typical morphology and distribution ( Flexural lichenification or linearity in adults; facial and extensor involvement in infants and children)
• Chronic or chronically relapsing dermatitis
• Personal or family history of atopic dermatitis( e.g asthma, allergic rhinitis, atopic dermatitis)

The course of atopic dermatitis may be divided into three phases: Infantile phase, Childhood phase, and Adult phase 

• Infantile phase: Face and scalp involvement is common as well as the extensor surfaces of the extremities and trunk
• Childhood phase: Eczema is observed on the flexural surfaces, including the neck, antecubital or popliteal fossae, wrists, and ankles
• Adult phase: Lichenification of the flexures and hands commonly occurs 

Associated findings

• Atopic triad of asthma, allergic rhinitis, and atopic dermatitis that is linked to allergen triggered IgE, White dermographism ( transiently blanched skin), Dermatographism, Keratosis pillaris( keratinized hair follicles), xerosis, Ichthyosis

Important signs

• Hertoghe’s sign( thinning of lateral eyebrows), Hyperkeratosis, and hyperpigmentation producing a dirty neck appearance. Atopic individuals often exhibit perioral, perinasal, and periorbital pallor “headlight sign”

Differential diagnosis

• Seborrheic dermatitis – Lesions are usually dry in atopic dermatitis and more greasy in seborrhic dermatitis. The most useful distinguishing feature in seborrhic dermatitis is the increased number of lesions on the axilla
• Psoriasis: onset is usually after adolescent years and lesions are typically covered with white silvery scales, located on the extensor surface 
• Infectious conditions: Mycoses, scabies 

Investigation

• Usually based on patient history and clinical appearance 
• Essential features – Pruritis and Eczema 
• Hanifin and Rajka’s criteria
• IgE
• Eosinophilia
• Patch testing
