Which dermatologic condition is commonly associated with atopy and allergic disease?

• A. Psoriasis
• B. Rosacea
• C. Atopic dermatitis
• D. Contact dermatitis

Answer: (C)

Atopy describes a genetic tendency to mount IgE-mediated responses to common environmental allergens, and it’s the family of allergic diseases that includes asthma, allergic rhinitis, and dermatitis. The skin manifestation most characteristically tied to this systemic allergic tendency is atopic dermatitis, a chronic, relapsing eczematous eruption with intense itch. It often starts in early life and is commonly seen in individuals with a personal or family history of allergic diseases and elevated IgE levels. Psoriasis is a separate autoimmune condition with well-defined plaques and is not part of the atopic spectrum. Rosacea involves facial flushing and vascular inflammation rather than an allergic diathesis. Contact dermatitis is an inflammatory skin reaction to external substances; while it can coexist with atopy, it is not the classic atopic-associated skin condition.
