The occurrence of furuncles is promoted by contamination and microtraumas of the skin, increased perspiration and fatty secretion, and metabolic disorders. Characteristic is a painful inflamed nodule with a central slough, or core. After the necrotic tissue is sloughed off, the skin heals and forms a scar. Furuncles usually appear on the neck, back, face, or back of the head. The presence of multiple furuncles is called furunculosis. Purulent necrotic inflammation of the skin and subcutaneous tissue around a group of hair follicles and sebaceous glands is called a carbuncle. Severe complications (purulent meningitis, sepsis) may result from a furuncle on the face.

Treatment includes applying an antiseptic to the skin and, sometimes, administering an antibiotic orally or intramuscularly. Prevention consists of proper personal hygiene, prevention of microtraumas of the skin, and prompt treatment of injured skin.
