Gram-negative folliculitis, a skin condition, was observed in six French patients resistant to standard acne treatments. Gram-negative bacilli were identified in some pustules, and effective treatments included targeted antibiotics and isotretinoin.

Area of Science:

  • Dermatology
  • Microbiology

Context:

  • Gram-negative folliculitis (GNF) is a rare skin infection.
  • First described in 1968, GNF has had limited reporting, with no prior cases documented in France.
  • This study details six GNF cases observed in France over 12 months.

Purpose:

  • To investigate Gram-negative bacillus (GNB) presence in acne vulgaris resistant to standard treatments.
  • To characterize the clinical presentation and bacteriology of GNF.
  • To evaluate treatment outcomes for GNF.

Summary:

  • Six patients with treatment-resistant acne vulgaris were evaluated for GNB.
  • Bacteriological examination of pustules revealed various GNBs, including Proteus mirabilis.
  • Lesions were limited to the face, presenting as superficial pustules or deep nodules.

  • Antibiotic therapy and isotretinoin were effective in treating GNF.

    • Impact:

    • Suggests the prevalence of GNF may be underestimated.
    • Highlights a stereotyped clinical presentation for GNF.
    • Demonstrates the efficacy of targeted antibiotic therapy and isotretinoin for GNF.
