Candida-associated diaper dermatitis is a skin infection beneath an infants diaper caused by Candida organisms (yeasts).

Alternative Names

Dermatitis - diaper and Candida; Candida-associated diaper dermatitis

Causes, incidence, and risk factors

Diaper rashes caused by infection with Candida species are extremely common in children. Candida is found everywhere in the environment and takes advantage of the warm, moist conditions beneath a diaper to cause superficial skin infections. The infection may begin as an intensely red patch with irregular (but sharp) boarders. Satellite lesions, smaller red patches just separated from the original patch's boarder, spread and blend in with the larger patch. The rash may spread to include the entire area covered by the diaper, including the scrotum and penis in boys, and the labia and vagina in girls.

Signs and tests

The classic appearance of the rash makes diagnosis of candidal diaper dermatitis possible by examination alone. The presence of yeast in a KOH (potassium hydroxide) preparation of skin scrapings is diagnostic. KOH test (microscopic examination of skin scrapings in KOH) demonstrates the presence of Candida

Treatment

Topical antifungal skin preparations will clear candidal infections. Some preparations are available as over-the-counter (OTC) creams and ointments. Some of these antifungals include:

Expectations (prognosis)

The rash usually responds well to treatment.

Complications

Calling your health care provider

Prevention

Prevention is difficult as the Candida organisms are in the environment. Using highly absorbent disposable diapers which keep the skin dry decreases the likelihood of infection.
