Which condition involves infection and swelling of skin tissues?

• A. Dermatitis
• B. Folliculitis
• C. Cellulitis
• D. Eczema

Answer: (C)

Cellulitis is a bacterial infection that involves the skin and the underlying subcutaneous tissues, leading to swelling, redness, warmth, and tenderness as the infection spreads. This deep involvement distinguishes it from dermatitis, which is inflammation of the skin surface and often presents with itchiness and a rash without a true deep infection. Folliculitis is an inflammation centered on hair follicles, usually with pustules around follicles, not a broad area of tissue swelling. Eczema is a chronic inflammatory skin condition with dry, itchy patches rather than an acute infection. Because the description focuses on an infection that causes swelling of the skin tissues, cellulitis is the best fit.
