Intertrigo is a skin inflammation or rash that occurs in warm, moist folds of the body where two skin surfaces chafe against each other. It is a very common skin rash that can show up throughout life. It most commonly appears on the inner thighs, armpits, groin, the crease on the back of the neck, the bottom of breasts in women and below the belly in obese people. It can be caused by a bacterial, yeast or fungal infection. Symptoms include a reddish-brown rash that looks raw and may ooze or itch. In severe cases, the skin may crack or bleed.
Intertrigo is often accompanied by an infection caused by yeast, other types of fungus, or bacteria. You are more likely to get these infections in skin folds because these are areas that are warm and tend to stay moist. This creates a welcome environment for the growth of germs.
If you have any symptoms of intertrigo, be sure to see your doctor. Your dermatologist can check for the presence of infection and may prescribe steroidal creams, oral antibiotics or antifungal medications (depending on the cause of the infection) to relieve itching and promote healing. Treatment for intertrigo focuses on keeping the affected area dry and exposed to air. Applying warm, moist compresses to the area can also help relieve itching. Keeping the area of the intertrigo dry and exposed to the air can help prevent recurrences, as can removing moisture from the area using absorbent fabrics.
