Yeast Infection Skin Rash

What Is a Yeast Infection?

Candidiasis is by far the most common type of yeast infection in human skin. Candidiasis is infection with Candida species. More than 20 species of Candida exist. The most common is Candida albicans. These fungi live on all surfaces of our bodies and only occasionally cause infection. Various types of Candida yeast infections are possible, including the following:

  • Perlèche (also termed angular cheilitis) is a softening of the skin with deep creases around the angles of the mouth.
  • Thrush is a candidal infection of the mouth and throat. White patches appear in the mouth. Thrush occurs most commonly in the mouths of people with chronic diseases, including diabetes, HIV/AIDS, and cancer, and those who use systemic corticosteroids or other medications that can suppress the immune system.
  • Intertrigo is an irritation of the folds of the skin. Candidal infections commonly occur in warm, moist body areas, such as the underarms, in the groin, under the breasts, between the legs, and under the folds of the skin of the abdomen of people who are obese. Any breakdown, cuts, or cracks in the skin may allow this organism to penetrate.
  • Candidal rash affects the diaper area (diaper rash). It is caused by candidal infection that is allowed to penetrate the skin due to moisture.
  • Candidal body rash can result from excess sweating, antibiotic use, or lack of movement leading to skin occlusion (for example, when a medication is applied to the skin and covered). It most commonly occurs in people with diabetes who are in the hospital.
  • Candidal vulvovaginitis is a candidal infection of the vaginal tract. Candida albicans fungus is a common inhabitant of the vaginal tract and can result in itching, redness, irritation, soreness, and burning. This is often referred to as a feminine yeast infection.
  • Congenital cutaneous candidiasis results from infection of an infant during passage through the birth canal. The rash appears within a few hours of delivery.
  • Candidal paronychia is a chronic inflammation of the nail fold of your hand or foot. In some cases, it causes a discharge with pus, and a soft, watery swelling of the area around the fingernail or toenail.
  • Erosio interdigitalis blastomycetica is a candidal infection between the finger webs. Skin softening and redness occur. Moisture trapped by rings is thought to cause the condition. Risk factors include people with diabetes and those who work with water (for example, house workers, launderers, and those exposed to strong chemicals).
  • Chronic mucocutaneous candidiasis is a condition that results from a genetic defect that leaves those who have it with thick, horny skin lesions and with nail abnormalities.
  • Systemic candidiasis is candidal infection throughout the body. This condition is rare. In systemic candidal disease, up to 75% of people may die. Even common mouth and vaginal yeast infections can cause critical illness, other health complications, and can be more resistant to normal treatment. This rash can manifest with bruises that can be felt. The bruises result from a reaction and response to Candida in blood vessels. Systemic yeast infections that return may be a sign of more serious diseases such as diabetes, leukemia, or AIDS.
  • Candida can also affect the digestive system and may be associated with ulcers and inflammatory bowel disease (IBD), but Candida colonization in the digestive tract is not usually associated with a yeast infection skin rash.
  • Ringworm is not the same as a yeast infection. Ringworm is another type of fungal infection caused by a type of fungus called a dermatophyte and can result in athlete's foot, jock itch, scalp infections, and infections of the nails and in skin folds.
