Candidiasis is an infection caused by the yeast Candida. Candida skin infections (cutaneous candidiasis) can occur at any site, but tends to favor warm, damp environments such as the skin folds and the groin region. Candida infections can also occur in the mouth (oral thrush) and in or around the nails (paronychia or onychomycosis). Young children, the elderly, diabetics, and patients using certain medications (antibiotics, steroids, chemotherapy agents) are at increased risk for candida infections. Infections of the skin typically cause a red, itchy rash. Pustules and satellite lesions (smaller lesions near the edges of the skin rash) are often noted. Candidiasis can be treated with topical and/or oral antifungals.
