Overview
Boil (furuncle) is the tender, deep, dome shaped skin infection of the hair follicle.
Pathophysiology
Folliculitis is the inflammation and infection of hair follicle.
Furuncle is a localized deep suppurative necrotizing form of folliculitis which involves dermis and subcutaneous tissue. Staphylococcus aureus is the most common causative agent. Following abrasion or cut the pathogen uses the entry site to invade and colonize the hair follicle leading to the formation of furuncle. The most commonly affected areas are the hairy parts such as scalp, face, buttocks, axillae, and areas which are subject to friction and perspiration. Group of furuncles coalesce to form carbuncle.
