A boil is a red, swollen, painful bump under the skin. It often looks like an overgrown pimple. Boils are often caused by infected hair follicles. Bacteria from the infection form an abscess, or pocket of pus. A boil, also called a furuncle, is a deep folliculitis, infection of the hair follicle.
Boils form when bacteria from the skin surface infiltrate a hair follicle. This intrusion of bacteria triggers an immune response that includes drawing white blood cells into the infected follicle to fight the infection. A boil, sometimes also referred to as a furuncle, is an infection involving a hair follicle on the skin.

Most boils and carbuncles are caused by Staphylococcus aureus. When these bacteria gain entrance to the skin, the infection settles in the hair follicles or the sebaceous glands. To combat the infection, large numbers of leukocytes travel to the site and attack the invading bacteria A boil, also called a furuncle, is a deep folliculitis, infection of the hair follicle.
