Nonneoplastic Epithelial Disorders of Vulvar Skin and Mucosa
Classification
Lichen sclerosis (lichen sclerosis et atrophicus)
Squamous cell hyperplasia (hyperplastic dystrophy without atypia)
Other dermatoses
Lichen planus
Psoriasis
The above terminology has replaced the use of the term vulvar "dystrophy" which lacks histopathologic specificity. The presence of cytologic" atypia" excludes a lesion from this category and places it in vulvar intraepithelial neoplasia (VlN)
Lichen sclerosis
A cutaneous disease affecting predominantly postmenopausa women
May also affect nongenital sites
Patients may have increased incidence of autoimmune disease
Clinically, pale white depigmented plaque of labia. Advanced cases may lead to agglutination of the labia and stenosis of the introitus
Other dermatoses
The majority of the vulva is skin or modified skin; therefore, any primary skin disease can affect the vulva
Lichen planus
Psoriasis
Lichen simplex chronicus
Condyloma Acuminata and VIN
Condyloma acuminata
