Intertrigo is caused by the macerating effect of heat, moisture, and friction. It is especially likely to occur in obese persons and in humid climates. The symptoms are itching, stinging, and burning. The body folds develop fissures, erythema, maceration, and superficial denudation (eFigure 6–18). Candidiasis may complicate intertrigo (eFigure 6–30). “Inverse psoriasis (eFigure 6–31),” seborrheic dermatitis, tinea cruris, erythrasma (eFigure 6–32), and candidiasis must be ruled out.
Maintain hygiene in the area, and keep it dry. Compresses may be useful acutely. Hydrocortisone 1% cream plus an imidazole or clotrimazole 1% cream is effective. Recurrences are common.
