A 2-month-old baby girl was brought to the office with a severe diaper rash that was not getting better with Desitin. Upon examination, the physician noted a white coating on the tongue and buccal mucosa. The diaper area was red with skin erosions and satellite lesions (Figure 95-1). The whole picture is consistent with candidiasis of the mouth (thrush) and the diaper region. The child was treated with oral nystatin suspension and topical clotrimazole cream in the diaper area with good results.

No differences in prevalence between genders or among ethnic groups.
One study showed an incidence of 19.4 percent in children ages 3 to 6 months.1
Higher incidence among formula-fed compared with breastfed infants.1
Condition typically begins around age 3 weeks, peaks at age 9 to 12 months, and then decreases with age until it resolves completely with toilet training.
Individual episodes last from 1 day to 2 weeks.
Aggravating factors include poor skin care, diarrhea, recent antibiotic use, and urinary tract abnormalities.
