In brief: Urticaria is hives

Urticaria is derived from a Latin word meaning to burn.
It is the same thing as hives. Hives lasting 6 weeks are not usually allergic in origin. Dermatitis means any kind of inflamed skin. Atopic dermatitis AKA eczema may be due to allergy. There are many other causes of dermatitis.
