Which type of conditions are typically characterized by redness, swelling, and itching?

• A. Lesions
• B. Infections
• C. Dermatitis
• D. Lesions and Infections

Answer: (C)

The condition characterized by redness, swelling, and itching is dermatitis. Dermatitis refers to inflammation of the skin that can result from various factors, such as allergens, irritants, or even environmental triggers. When dermatitis occurs, the skin typically displays signs like redness (due to increased blood flow to the area), swelling (inflammation often leads to puffiness), and intense itching (pruritus) as a response to irritation or an allergic reaction.

This condition can manifest in different forms, including contact dermatitis, atopic dermatitis, or seborrheic dermatitis, each with its own triggers and characteristics, but they all share the common symptoms of redness, swelling, and itching. Understanding dermatitis is essential for skin care professionals as it guides appropriate treatment and management strategies.
