allergic eczema
Definition
Noun: A type of skin inflammation (eczema) that is specifically triggered by an allergic reaction. It is characterized by itchy, red, swollen, and cracked skin.
Usage
The term "allergic eczema" is used to describe a medical condition where the skin's inflammatory response is directly caused by contact with or exposure to an allergen. It distinguishes this condition from other forms of eczema that may have different causes, such as genetic or irritant factors.

Advanced Usage
- Clinical Context: In medical literature, "allergic eczema" is often discussed in the context of atopic dermatitis when a specific allergic component is identified, or more specifically as allergic contact dermatitis.
- Formal Description: The condition represents a delayed hypersensitivity (Type IV) immune response in the skin.
