Management of Fungal Infection of the Groin and Labia with Wound Development

For a fungal infection of the groin and labia that failed to respond to nystatin powder and has progressed to a wound, treatment should consist of oral fluconazole 150 mg every 72 hours for 3 doses, combined with a topical azole cream applied twice daily for 7-14 days. 1

Assessment and Diagnosis

  • Confirm diagnosis through physical examination looking for:
    • Erythema, excoriation, fissures in the groin and labial area
    • Presence of wound with possible secondary infection
    • White, thick discharge if present
  • Laboratory confirmation:
    • Perform KOH preparation to visualize yeast or hyphae
    • Consider fungal culture if diagnosis is uncertain or treatment failure occurs
    • Check pH (should be normal at 4.0-4.5 for typical candidiasis)

Treatment Approach

First-Line Treatment

  1. Oral therapy:

    • Fluconazole 150 mg every 72 hours for 3 doses 1
    • This systemic approach is necessary due to:
      • Previous treatment failure with topical nystatin
      • Presence of wound indicating complicated infection
  2. Topical therapy (concurrent):

    • Apply azole cream (clotrimazole 1% or miconazole 2%) to affected area twice daily for 7-14 days 1
    • Extend application 1-2 cm beyond visible lesions
    • Continue treatment for at least 7 days after clinical clearing 2

Wound Care

  • Gentle cleansing with mild soap and water
  • Keep area clean and dry between applications
  • Avoid tight-fitting clothing and synthetic underwear
  • Consider non-adherent dressing if wound is exudative

For Non-Responsive Cases

If no improvement after 7 days or worsening of symptoms:

  • Consider alternative diagnosis or mixed infection
  • Switch to a different azole or consider boric acid (600 mg) vaginal capsules daily for 14 days 1
  • For suspected non-albicans species (particularly C. glabrata), consider boric acid as it may be more effective 1

Special Considerations

If C. glabrata is Suspected or Confirmed

  • C. glabrata often responds poorly to azole therapy 1
  • Consider boric acid contained in gelatin capsules (600 mg) intravaginally daily for 14 days 1
  • Nystatin intravaginal suppositories may be effective for C. glabrata when azoles fail 3

For Recurrent Infections

  • After successful treatment, consider maintenance therapy with fluconazole 150 mg weekly for 6 months 1
  • Address predisposing factors:
    • Evaluate for diabetes or immunosuppression
    • Review medications (antibiotics, corticosteroids)
    • Recommend cotton underwear and loose-fitting clothing

Follow-up

  • Schedule follow-up within 7-10 days to assess treatment response
  • If wound is not healing or infection persists, consider:
    • Culture to identify specific pathogen and sensitivities
    • Evaluation for underlying conditions affecting immune response
    • Possible referral to dermatology or gynecology

Prevention of Recurrence

  • Maintain good hygiene practices
  • Keep area dry (use absorbent powders without cornstarch)
  • Wear loose cotton clothing
  • Change out of wet clothing promptly
  • Avoid potential irritants (perfumed soaps, douches)

The presence of a wound following failed nystatin treatment indicates this is a complicated vulvovaginal candidiasis requiring more aggressive therapy than typical cases. The combination of oral and topical antifungals provides comprehensive treatment targeting both the superficial infection and potential deeper tissue involvement.
