Candida is a common type of fungus found almost everywhere in the general environment. It also colonizes human skin and grows within the mouth, throat, vagina and digestive tract. These fungi are normally harmless. However, some candida species can overgrow and cause an infection called candidiasis.
The immune system and normal balance of bacteria limit candida growth. Candida infections, commonly known as yeast infections, occur when candida grows out of control. This can happen if something, such as antibiotics or other medications, alters the native microbiota. Illnesses that weaken the immune system can also allow candida overgrowth.
Superficial skin infections are commonly related to candida overgrowth and can cause a wide range of symptoms. Mild infections may appear as white, light brown or red patches of dry, scaly skin on the arms, legs, back and trunk.6‘Yeast Infection.’ Johns Hopkins Medicine, www.hopkinsmedicine.org/health/conditions-and-diseases/candidiasis-yeast-infection
Some infections cause well-defined, red-rimmed skin lesions of various shapes and sizes. Small red pustules may occur in skin folds, such as the underarms, underneath breasts, between fingers and toes and around the groin.5‘Candidiasis.’ NORD (National Organization for Rare Disorders), rarediseases.org/rare-diseases/candidiasis Skin folds may also develop a red, moist and irritated rash with an unpleasant odor.6‘Yeast Infection.’ Johns Hopkins Medicine, www.hopkinsmedicine.org/health/conditions-and-diseases/candidiasis-yeast-infection
