8. TYPES OF ECZEMA
Atopic Dermatitis
Genetically influenced, chronic, relapsing disease
associated with immunologic irregularity involving
inflammatory mediators, exaggerated by a cutaneous
response to environmental allergens; associated with
allergic rhinitis and asthma; most severe in childhood.
9.
10. Multiple presentations include :-
1) Acute-bright erythema, oozing vesicles, with extreme pruritus
2) Subacute-scaly, light red to red-brown plaques
3) Chronic stage-thickened skin with accentuation of skin markings
(lichenification), possible hyperpigmentation; dry skin; common
in antecubital and popliteal space in adults;
11. • Lubrication of dry (xerotic) skin
• Topical immunomodulators (pimecrolimus [Elidel]; Tacrolimus
[Protopic])
• Topical corticosteroids, systemic corticosteroids if severe,
• Phototherapy for relapses
• Reduction of stress reduces flares
• Antibiotics for secondary infection as needed
12. Manifestation of delayed hypersensitivity
Absorbed agent acting as antigen
Sensitization after several exposures
Appearance of lesions 2-7 days after contact with allergen
13.
14. Red papules and plaques
Sharply circumscribed with occasional vesicles
Usually pruritic
Area of dermatitis frequently takes shape of causative
agent (e.g., metal allergy and band-like dermatitis on
ring finger)
15. • Topical corticosteroids, antihistamines
• Skin lubrication
• Elimination of contact allergen
• Avoidance of irritating affected area
• Systemic corticosteroids if sensitivity severe
