Lichen planus is an uncommon cutaneous disease that can affect the vulva. Vulvar pruritus and pain are common symptoms in patients with genital involvement. Examination reveals an erythematous, friable vestibule with adherent exudate. Marked resorption of the labia minora and atrophy may occur in time. Diagnosis is based on associated clinical findings involving the oral mucosa and/or the skin and on vulvar biopsy.
