MOIST & SWEAT

Intertrigo is an inflammatory condition of skin folds, induced or aggravated by heat, moisture, maceration, friction, and lack of air circulation. Intertrigo frequently is worsened or colonized by infection, which most commonly is candidal but also may be bacterial, fungal, or viral.

Intertrigo occurs more often among overweight individuals, those with diabetes, those restricted to bed rest or diaper use, and those who use medical devices, like artificial limbs, that trap moisture against the skin. An intertrigo usually develops from the chafing of warm, moist skin in the areas of the inner thighs and genitalia, the armpits, under the breasts, the underside of the belly, behind the ears, and the web spaces between the toes and fingers.

An intertrigo usually appears red and raw-looking, and may also itch, ooze, and be sore. The appearance of intertrigo is dependent on the skin area involved and the duration of inflammation. Erythema and weeping may progress to maceration and crusting. Fissuring may follow erosion. Pustules or vesicles may herald infection. In the perineum, depths of the skin folds are involved compared to purely irritant diaper dermatitis in which only convex surfaces are involved.
