Overview

Boils (furuncles) are a localized deep suppurative necrotizing form of folliculitis which involve the dermis and the subcutaneous tissue. Staphylococcus aureus is the most common causative agent. Following an abrasion or cut, the pathogen uses the wound site to invade and colonize the hair follicle. This leads to the formation of tender, erythematous, perifollicular nodule. The boil later becomes painful and fluctuant leading to discharge of pus and formation of necrotic plugs, which may leave a scar.[1]

Pathophysiology

Pathogenesis

  • A group of furuncles coalesce to form a carbuncle.

Schematic of Pathogenesis

Associated Conditions

Gross Pathology

On gross pathology, characteristic findings of boils include firm, tender, red, dome shaped nodules, which progress to fluctuant, pus-filled, and painful lesions. Boils may vary in size.

Microscopic histopathological analysis

On microscopic histopathological analysis, characteristic findings of boils include:

  • Superficial (primarily involving the infandibulum)
  • Deep
