- Affects patients between ages 30 to 60 years
- Much less common than Vulvar Lichen Sclerosus as a cause for Vulvar Dermatitis
- Types
- Erosive lichen planus (most common variant)
- Glassy appearing white Papules and Plaques
- Progression to ulcers and Erosions with altered Vulvar anatomy
- Vagina involved in 70% of cases (vagina not involved in Lichen Sclerosus)
- Vaginitis characterized by friable, tissue with adhesions and serous discharge
- May concurrently involve vulvovaginal-Gingival syndrome
- Papulosquamous lichen planus
- Poorly demarcated pink opaque Papules
- Hypertrophic lichen planus
- Perineum and perianal hyperkeratotic lesions
- May present as Squamous Cell Carcinoma
- Symptoms
- Vulvar Pruritus or burning
- Postcoital bleeding
- Dyspareunia
- Signs
- See types above
- Speculum exam is very uncomfortable in erosive lichen planus due to associated Vaginitis
- Labs: Erosive Lichen Planus
- Punch Biopsy of Erosion borders
- KOH and wet prep to evaluate for fungal and bacterial causes of Vaginitis
- Differential Diagnosis: Erosive Lichen Planus
- Lichen Sclerosus
- Pemphigoid
- Pemphigous vulgaris
- Behcet's Syndrome
- Vaginitis
- Drug Reaction
- Management
- Hydrocortisone suppositories for vaginal lesions
- Topical Corticosteroid for vulvar lesions (or applied on vaginal dilator for erosive Vaginitis)
- Choice of strength depends on severity
- Level 1: Clobetasol Propionate 0.05% ointment (ultra-potent bid in severe cases)
- Level 2: Betamethasone dipropionate 0.05% ointment
- Level 3: Betamethasone dipropionate 0.05% cream
- Level 4: Triamcinolone acetonide 0.1% ointment (medium potency qhs in mild cases)
