Definition
Intertrigo is an inflammation of the superficial layers of the skin, caused by the permanent or intermittent rubbing of two skin surfaces. Typical locations are the inframammary fold, the interdigital spaces of the hands and feet, the inguinal and intergluteal region, the neck and the armpits. In these locations, the continuous friction between the two surfaces causes a local increase in temperature and humidity. The sweat, stagnating, favors skin maceration with formation of patches and plaques. Moreover, mechanical rubbing makes susceptible to colonization by bacteria (mostly Staphylococcus aureus, Streptococcus pyogenes, Proteus spp and Pseudomonas aeruginosa ), yeasts ( Candida ) and dermatophytes. The microorganisms involved may belong to the resident or transient flora.
Intertrigo is more evident in overweight and obese people.

Further indications
Intertrigo presents with redness, alteration of skin integrity (de-epithelialization), desquamation, itching and burning on the bottom of the affected fold. Skin maceration and decomposition of cellular debris contribute to the maintenance of irritation and can cause a bad smell (bromidrosis). If the condition is neglected, erosions, fissures, vesicles and pustules may appear.
The diagnosis is based on clinical and microbiological evaluation; culture tests can guide treatment. If yeasts or bacteria are present, the therapy involves the local application of ointments or antifungal lotions, or the administration of antibiotics. In the absence of infections, however, the use of powders (eg talc) or absorbent pastes can help reduce the problem.
