When to Refer an Adult Female Patient with Itchy Vulva to a Specialist

Refer to a specialist vulval clinic if the patient has persistent symptoms despite appropriate first-line treatment with topical corticosteroids, recurrent disease requiring ongoing management, atypical presentation, concern for malignancy or intraepithelial neoplasia, or severe architectural changes requiring surgical intervention. 1

Initial Assessment and Management in Primary Care

Before considering referral, establish the underlying diagnosis and initiate appropriate treatment:

For Suspected Vulvovaginal Candidiasis (VVC)

• Confirm diagnosis with wet preparation or Gram stain showing yeasts/pseudohyphae, or positive culture, in the presence of pruritus and erythema 1
• Treat uncomplicated VVC with topical azoles (3-7 days) or single-dose fluconazole 150 mg 1, 2
• Self-treatment with OTC preparations is appropriate only for women with previously diagnosed VVC who have recurrence of identical symptoms 1
• Any woman whose symptoms persist after OTC treatment or who has recurrence within 2 months should seek medical care 1

For Suspected Lichen Sclerosus (LS)

• Initiate clobetasol propionate 0.05% ointment following clinical diagnosis (once daily for 1 month, alternate days for 1 month, twice weekly for 1 month) combined with soap substitute and barrier preparation 1
• Document baseline architectural changes using diagram or photograph 1
• Provide patient education on avoiding irritants and fragranced products 1

Clear Indications for Specialist Referral

Immediate/Urgent Referral Required

Refer urgently if:

• Suspected malignancy or vulvar intraepithelial neoplasia (VIN) - new erosions, ulceration, lumps, hyperkeratotic or fixed erythematous areas 1
• Severe architectural changes including fusion causing functional difficulties 1
• Pathological uncertainty about intraepithelial neoplasia 1

Referral After Failed Primary Treatment

Refer to specialist vulval clinic if:

For Vulvovaginal Candidiasis

• Recurrent VVC (≥3 episodes per year) requiring maintenance therapy 2, 3
• Non-albicans Candida species identified on culture, particularly C. glabrata, which requires longer therapy (7-14 days) with non-fluconazole azoles 1, 2
• Severe VVC with extensive vulvar erythema, edema, excoriation, and fissure formation not responding to 7-14 days of topical azole or two doses of fluconazole 1
• Persistent symptoms after appropriate antifungal treatment 1

For Lichen Sclerosus

• No response to ultrapotent topical steroid after 3 months of appropriate use 1
• Ongoing troublesome symptoms despite treatment 1
• Atypical disease presentation 1
• Previous vulvar cancer or any type of VIN 1
• Development of vulvodynia - burning or soreness persisting despite successful LS treatment 1

For Other Dermatologic Conditions

• Diagnostic uncertainty after initial evaluation 4, 5
• Multiple failed empiric treatments for presumed infectious/inflammatory etiologies 6, 7
• Complex presentations with multiple coexisting conditions (candidiasis, atopy, dermatographism, irritant contact dermatitis) 6

Patients Who Can Be Managed Long-Term in Primary Care

Continue primary care management with annual follow-up for:

• Uncomplicated LS responding well to topical treatment - after two specialist visits (at 3 and 9 months) confirming good control 1
• Simple VVC with complete symptom resolution after treatment 1
• Patients confident in self-management with clear instructions for self-monitoring 1

Critical Pitfalls to Avoid

• Do not delay referral for suspected malignancy - any persistent erosion, ulcer, or lump requires biopsy to exclude intraepithelial neoplasia or invasive squamous cell carcinoma 1
• Do not assume recurrent symptoms are always infection - obtain cultures to identify non-albicans species (present in 10-20% of recurrent VVC) before repeated empiric treatment 1, 2, 3
• Do not discharge patients with LS to primary care without clear self-monitoring instructions - over half of women discharged from UK vulval clinics are not followed up appropriately 1
• Do not overlook dermatographism as a cause of vulvar symptoms, especially if exacerbated by sexual activity, menstruation, or tight clothing - easily diagnosed with scratch test and treated with antihistamines 7
• Do not continue ineffective treatment beyond 2 months - persistent or recurrent symptoms warrant specialist evaluation 1
