Which term describes the inflammation of the skin characterized by redness, swelling, itching, or blistering?

The term that accurately describes the inflammation of the skin characterized by redness, swelling, itching, or blistering is dermatitis. Dermatitis is a general term that encompasses various skin conditions that can arise due to irritants, allergens, or other factors. This inflammation leads to the symptoms mentioned, such as redness and swelling, contributing to the overall discomfort experienced by individuals affected by this condition.

Eczema specifically refers to a type of dermatitis that often manifests in itchy patches of skin and can be triggered by allergens or irritants. While it shares some characteristics with dermatitis, it is not as broad a term.

A lesion refers to any abnormal change in the tissues of the body, which can occur in various forms but does not specifically denote inflammation.

A pustule is a small blister or pimple on the skin containing pus, primarily associated with infections or inflammatory conditions but is not a term used to describe the overall condition of inflammation in the skin itself.

Thus, dermatitis is the most appropriate term as it accurately encapsulates the various symptoms and characteristics of skin inflammation.
