Pustules

  • Definition
    • Pustules are small, inflamed, pus-filled, blister-like sores (lesions) on the skin surface.

  • Considerations
    • Pustules are common in acne. They may occur anywhere on the body, but are most commonly seen in these areas:

      • Back
      • Face
      • Over the breastbone
      • Shoulders
      • Sweaty areas, such as the groin or armpit

      Pustules may be a sign of a bacterial infection. They should be checked by a health care provider.
