Pustules

 

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

Pustules are common in acne and folliculitis (inflammation of the hair follicle). 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 an infection. In some cases, they are non-infectious and associated with inflammation in the skin or taking certain medicines. They should be checked by a health care provider and may need to be tested (cultured) for bacteria or fungus.
