An intertrigo is an inflammation (rash) of the body folds.
The term "intertrigo" commonly refers to a bacterial, fungal, or viral infection that has developed at the site of broken skin due to such inflammation. A frequent manifestation is candidal intertrigo.
Intertrigo is caused when frictional forces, enhanced by heat and moisture 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.
Risk factors for intertrigo include obesity, heat, and humidity.
An intertrigo usually appears red and raw-looking, and may also itch, ooze, and be sore. Intertrigo occur 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. Also, there are several skin diseases that can cause an intertrigo to develop, such as dermatitis or inverse psoriasis.
Intertrigo is diagnosed by visual inspection after eliminating infectious causes.
Treatment involves the reduction of frictional forces, humidity, and heat in the skin folds.
Intertrigo dermatitis can be infected by bacteria and fungi. Eruptions in the skin folds can occur in a number of other dermatological conditions aside from intertrigo.
Intertrigo can be prevented by losing weight and applying lubricating topical preparations prior to athletic endeavors.
The prognosis of intertrigo is excellent.
