Intertrigo is a rash in the flexures or skin folder (e.g. neck folds ,axillar, groin, finger webs). It can affect a single skin fold or can affect multiple sites. It is often causes by skin friction in a mios environment. Nappy rash, or napkin dermatitis, is a type of intertrigo occurring in babies and infants.

The skin is erythematous, moist, and can lead to peeling and fissures. There are many potential infections that can cause intetrigo including candida, tinea, impetigo, staph aureus, folliculitis. It can lead to secondary bacterial infection.

Treatment will depend on the underlying cause (i.e. which organism is responsible). Skin should be kept dry where possible.
