Definition of Diaper dermatitis - Candida-associated:

Candida-associated diaper dermatitis is an infection of the skin beneath an infant's diaper. It is caused by yeasts (Candida organisms).

Causes, incidence, and risk factors:

Diaper rashes caused by infection with Candida species are very common in children. Candida is found everywhere in the environment, and takes advantage of the warm, moist area under a diaper to cause infections on the skin.

The infection may begin as a very red patch with irregular (but sharp) borders. Smaller red patches can spread out from the original border 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.

Candidal diaper rashes can be associated with oral candidiasis, or thrush. In this case, the oral infection must also be treated.
