Dermatitis - diaper and Candida; Candida-associated diaper dermatitis; Diaper dermatitis
You may notice the following in your child's diaper area:
Bright red rash that gets bigger
Fiery red and scaly areas on the scrotum and penis in boys
Red or scaly areas on the labia and vagina in girls
Pimples, blisters, ulcers, large bumps, or pus-filled sores
Smaller red patches (called satellite lesions) that grow and blend in with the other patches
Older infants may scratch when the diaper is removed.
Diaper rashes usually do NOT spread beyond the edge of the diaper.
Signs and tests
Yeast or Candida-related diaper rashes often can be diagnosed by the appearance alone. The KOH test can confirm a Candida diagnosis.
