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


Pustules on the skin surface are relatively common occurrences. Pustules are common in Acne and are the yellowish topped, small, pus-filled lesions that adolescents are notorious for picking and squeezing.

Pustules may occur anywhere on the body, but they are common in the usual acne areas (face, shoulder, back, and over the breastbone), and in areas of increased sweating such as the groin and armpit.
