Furunculosis is a deep infection of hair follicles generally caused by the bacterium Staphylococcus aureus And mainly affecting the face. I furuncles, which can occur either singly or in groups, present as a raised, reddened lesion with a hard, painful nodular central part; over time, the furuncles may enlarge and pus formation may occur at the top of them.
Furuncles can form due to excess production of sebum by the sebaceous glands of the epidermis (due to genetic or hormonal reasons), such that they clog the pores of the skin and interact with the resident microbial microflora: thus an inflammatory reaction is generated, resulting in lesion formation. In some cases, however, the formation of furuncles may be related to the presence of an ingrown hair or foreign body in the hair follicle.
