Intertrigo is best described as which condition?

• A. Inflammatory condition of skin folds aggravated by heat, moisture, friction; Candida satellite lesions
• B. Dry eczema on extensor surfaces
• C. Psoriasis of scalp
• D. Fungal tinea corporis

Answer: (D)

Intertrigo is an inflammatory reaction that occurs in skin folds when heat, moisture, and friction trap moisture and irritate the skin. The warm, damp environment in folds like the armpits, groin, or under the breasts often leads to maceration and irritation, and Candida infection can complicate this picture, producing small satellite lesions around the main rash. This description fits intertrigo best. Dry eczema on extensor surfaces tends to appear on the elbows and knees as dry, itchy patches rather than in skin folds. Psoriasis of the scalp presents as silvery plaques on the scalp, not specifically in folds. Tinea corporis is a ring-shaped fungal infection with central clearing and more typical involvement of the trunk or limbs, not confined to skin folds.
