Inflammation and maceration of the skin due to continuous rubbing in a frequently moist area. In many cases, the affected area becomes infected by bacteria or fungi. It is more common in people who are overweight and/or have diabetes.
It generally appears in the folds where rubbing is frequent and sweat accumulates, such as the armpits, groin and submammary folds.
It manifests with a reddening of the skin, which may be accompanied by intense itching.
Diagnosis is clinical, by questioning and physical examination.
Treatment is based on reducing, or if possible eliminating, the triggering factor with antiperspirants and reducing excess weight. If it is associated with an infection, antibiotics should be administered if it is a bacterial infection and antifungals if it is caused by fungi.
