Intertrigo is an inflammatory condition of skin folds induced or aggravated by heat, moisture, maceration, friction and lack of air circulation. It commonly affects the axilla, perineum, inframammary creases and abdominal folds.
Diaper dermatitis shows significant overlap with with intertrigo.
Intertrigo commonly complicates obesity and diabetes. Intertrigo develops from mechanical factors and secondary infection. Heat and maceration are central to the process. Opposing skin surfaces rub, causing erosions that become inflamed. Sweat, feces, urine and vaginal discharge may aggravate intertrigo in both adults and infants.
