Which skin condition is characterized by red, itchy, and inflamed patches?

Eczema is a skin condition characterized by red, itchy, and inflamed patches, making it distinct in its presentation. It often appears as dry, flaky skin that can lead to intense itching and discomfort. This condition may be triggered by various factors, including environmental irritants, allergens, stress, or changes in weather. The inflammation can cause the skin to become red and swollen, which aligns with the characteristics described in the question.

In contrast, psoriasis typically presents with thick, silvery scales on red patches of skin and is associated with a different underlying mechanism involving immune system dysfunction. Acne primarily involves the presence of pimples, blackheads, and cysts due to clogged hair follicles, and it does not usually manifest as inflamed patches. Dermatitis is a broader term that encompasses a range of inflammatory skin conditions, but eczema specifically refers to a particular type characterized by the combination of itchiness, redness, and inflammation, which is why it is identified as the correct answer in this scenario.
