Synonym(s): Deep pyoderma

Contributor(s): Rosanna Marsella, David Scarff

Introduction

  • Cause: varied - usually an extension from deep bacterial folliculitis and furunculosis Skin: deep folliculitis and furunculosis. Occasionally, secondary to lymphangitis or lymphadenitis.
  • Signs: pruritus, pain, multiple purulent discharges, lymphadenopathy, sepsis.
  • Diagnosis: history, clinical signs, microscopy, bacteriology, histopathology.
  • Treatment: long-term systemic antibiotics and topical antimicrobials.
  • Prognosis: guarded to good.

Pathogenesis

Predisposing factors

General
  • Endocrine disease.
  • Immunosuppression.

Pathophysiology

  • Continuation of superficial pyoderma deeper into follicles → rupture of follicular wall → pyogranulomatous perifolliculitis or furunculosis in dermis and subcutis → extension along tissue planes → fistule on surface or cellulitis and panniculitis in subcutaneous and fatty tissues.
  • Occasionally extension of lymphangitis or lymphadenitis → cellulitis.
