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
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
Topical therapy (concurrent):
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.
