What condition is characterized by itchy, red, and inflamed skin with blisters?

The condition characterized by itchy, red, and inflamed skin with blisters is dermatitis. Dermatitis refers to an inflammation of the skin, which can be triggered by a variety of factors, including allergens, irritants, or underlying health conditions. The symptoms typically include redness, swelling, itching, and sometimes the presence of blisters, particularly in allergic or contact dermatitis.

Dermatitis can manifest in different forms, such as atopic dermatitis (commonly known as eczema) or contact dermatitis. In these cases, the inflammation occurs as a direct response to stimuli, leading to the distinct features of redness and blister development.

In contrast, impetigo is a bacterial skin infection that usually presents with sores and honey-colored crusts, rather than blisters. Scabies is caused by a mite infestation that leads to intense itching and a rash resulting from an allergic reaction to the mites, but it typically does not present with blisters like dermatitis does. Cellulitis is a deeper tissue infection characterized by redness and swelling, but it typically does not feature blisters or the intense pruritus commonly associated with dermatitis. Thus, dermatitis stands out as the condition that matches the description of itchy, red, and inflamed skin with blisters.
