Intertrigo: Symptoms & Signs

Medically Reviewed on 9/10/2019

Intertrigo is a form of dermatitis, or inflammation of the skin, that affects skin folds anywhere on the body. Obesity is a risk factor for developing intertrigo.

Signs and symptoms of intertrigo include reddened skin, burning, itching, and raw skin in the skin folds. Other associated symptoms can include oozing, cracked or crusty skin, or scaling skin. Intertrigo is most commonly found in the groin, under the breast, and in the armpits. These are areas where skin comes in contact with and rubs against other skin and are known as intertriginous areas.

Causes of intertrigo

A combination of frictional rubbing, heat, and moisture causes intertrigo. Infections with yeasts, dermatophyte fungi, or bacteria can complicate intertrigo.
