Pathogenesis

Etiology

  • Unknown.
  • Mucocutaneous sites ideal for bacterial multiplication/overgrowth, including resident bacteria and yeast, due to humidity/limited ventilation.

Predisposing factors

General
  • Allergies may be a predisposing factor - rubbing face → trauma → bacterial and yeast proliferation.

Pathophysiology

  • Inflammation of perioral skin → self trauma → fissuring, crusting and erosion → secondary infection.
  • Initial erythema and swelling of mucocutaneous area, particularly perioral skin.
  • Tenderness → self mutilation → cracking, fissures and erosion → secondary infection.

Timecourse

  • May develop over short or long timecourse.
