Intertrigo is inflammation of the skin folds. It tends to occur in warm, moist areas of the body where two skin surfaces rub or press against each other. Such areas are called intertriginous areas.
Intertrigo affects the top layers of skin. It is caused by moisture, bacteria, or fungus in the folds of the skin. Bright red, well-defined weeping patches and plaques are seen in the folds of the neck, armpits, elbow pits, groin, finger and toe webs, or backs of the knees. If the skin is very moist, it may begin to break down. In severe cases, there may be a bad odor.
The condition is most common in people who are obese. It may also occur in people who must stay in bed or who wear medical devices such as artificial limbs, splints, and braces. These devices may trap moisture against the skin.
Intertrigo is common in warm, moist climates.
It may help to lose weight and change your body position often.
