Intertrigo is most accurately described as which of the following statements?

• A. It is a rash on the face
• B. It is a fungal infection of the scalp
• C. It occurs in skin folds and is not specific to diabetes
• D. It occurs only in the genital area

Answer: (C)

Intertrigo is inflammation that develops in skin folds where moisture and friction are common. It shows up in areas such as the armpits, beneath the breasts, groin, or any place skin rubs together and stays warm and damp. It’s not limited to the face or to the genital area, and it isn’t defined by diabetes alone—people without diabetes can develop it, though diabetes and obesity can raise risk due to increased moisture, folding, and immune factors. Clinically you’ll see red, macerated patches in folds, sometimes with fissures, and there may be secondary infections like Candida causing satellite lesions. Treatment focuses on keeping the area dry and reducing friction, using breathable clothing and barrier creams, and addressing any superimposed infection if present. This description fits intertrigo as occurring in skin folds and not being specific to diabetes.
