Definition of Pustule

Pustule: A pustule is a small collection of pus in the top layer of skin (epidermis) or beneath it in the dermis. Pustules frequently form in sweat glands or hair follicles. Pus is a mixture of inflammatory cells and liquid.

Put somewhat more simply, a pustule is a little pocket full of pus.
