A carbuncle is a cluster of boils, draining pus onto the skin. It is usually caused by bacterial infection, most commonly with Staphylococcus aureus or Streptococcus pyogenes, which can turn lethal.
Boils and carbuncles are often caused by a type of bacteria known as Staphylococcus aureus (staph bacteria) infecting one or more hair follicles.

A carbuncle is a dome-shaped collection of boils that usually develops over the space of a few days. They most often occur on the back, thighs, or the back of the neck. A fully grown carbuncle can be more than 10cm (4 inches) in size, and will leak pus from a number of points.
