Evaluation and Management of Vulvar Pain

Begin evaluation by performing a focused physical examination looking specifically for porcelain-white plaques, fissures, ecchymosis, architectural changes (labial fusion, buried clitoris, introital narrowing), and erythema to distinguish between inflammatory dermatoses (particularly lichen sclerosus), infectious causes, and vulvodynia. 1, 2

Initial Clinical Assessment

Key Physical Examination Findings

  • Lichen sclerosus (most common in postmenopausal women): Look for porcelain-white plaques, fragile atrophic skin, characteristic fissures in a figure-eight pattern around vulva and anus (pathognomonic), ecchymosis, purpura, and architectural changes including labial fusion, buried clitoris, or introital narrowing 1

  • Vulvovaginal candidiasis: Examine for vulvovaginal erythema, white discharge, and measure vaginal pH (should be ≤4.5 if candidiasis) 2

  • Vulvodynia/dysesthetic vulvodynia: Burning pain without visible depigmentation or structural changes on examination 1

Diagnostic Testing

  • Perform wet mount with 10% KOH to visualize yeasts or pseudohyphae if infectious etiology suspected 2
  • Measure vaginal pH: normal is ≤4.5 (candidiasis), elevated >4.5 suggests bacterial vaginosis 2
  • Biopsy is mandatory if diagnosis is uncertain, disease fails to respond to treatment, or there is suspicion of neoplastic change 1

Treatment Algorithm

For Lichen Sclerosus (Depigmented, Burning, Painful Areas)

Topical corticosteroids are first-line treatment for lichen sclerosus, which requires long-term monitoring due to risk of architectural changes and potential malignant transformation 1, 3

For Vulvovaginal Candidiasis

  • First-line: Fluconazole 150 mg oral single dose OR short-course topical azole therapy (1-3 days) with 80-90% cure rates 2

  • Topical options: Clotrimazole 1% cream 5g intravaginally for 7-14 days, miconazole 2% cream 5g intravaginally for 7 days, or terconazole 0.8% cream 5g intravaginally for 3 days 2

  • Pregnant women: Use only topical azoles for 7 days (oral agents contraindicated) 2

  • Recurrent candidiasis (≥4 episodes/year): Longer initial therapy followed by maintenance regimen for 6 months; evaluate for predisposing conditions (diabetes, immunosuppression, HIV, antibiotic use) 2

For Vulvodynia (Diagnosis of Exclusion)

When infectious and inflammatory causes are excluded, vulvodynia management includes:

  • Vulvar care measures and self-management strategies 4, 5
  • Tricyclic antidepressants for neuropathic pain component 4
  • Physical therapy with biofeedback 4
  • Calcium citrate supplementation 4
  • Consider surgical intervention or laser therapy in refractory cases 4

Imaging Considerations

Physical examination is the foundation of evaluation; imaging is only indicated when physical examination is abnormal or specific pathology is suspected. 6

  • Transvaginal and transabdominal ultrasound with Doppler are the initial imaging modalities if pelvic mass or cyst is palpated 6

  • MRI pelvis is reserved for problem-solving when ultrasound is nondiagnostic, or when evaluating pelvic floor muscular hypertonicity in chronic pelvic pain syndromes 6

  • CT and plain radiography have no role in primary evaluation of vulvar pain 6

Critical Pitfalls to Avoid

  • Do not assume depigmentation is benign: Lichen sclerosus carries risk of malignant transformation and requires biopsy if diagnosis uncertain or treatment fails 1

  • Do not use oral fluconazole in children under 12 years due to limited safety data 3

  • Do not delay biopsy when architectural changes, non-healing lesions, or treatment failure occurs 1

  • Do not prescribe home-going opioids for routine postoperative vulvar surgery pain; multimodal opioid-sparing analgesia with scheduled NSAIDs and acetaminophen is sufficient 6

Follow-Up and Monitoring

  • Lichen sclerosus requires regular long-term follow-up due to risk of progression and malignancy 1

  • Candidiasis symptoms persisting beyond 2 months warrant re-evaluation 3

  • Vulvodynia is often chronic, requiring regular medical follow-up and consideration of support group referral 4, 5
