atopic dermatitis vs contact dermatitis

so the word "atopic" indicates it's hypersensitive type 1 and "contact" indicates it's type 4 right?

I had a UW q presenting an adult pt with contact dermatitis with a past medical hx of atopic dermatitis as a child. So people who get atopic dermatitis as a child are vulnerable to contact dermatitis later on in their life?

They're completely different, as you've said already. No, one doesn't increase the probability of the other. Atopy is your reactive airway/asthma + eczema + rhinoconjunctivitis + eosinophilic esophagitis constellation, all mediated via a type-I IgE process. But the type-IV T-cell response to nickel, rubber, sunscreen, plant secretions, etc., is unrelated.
