Differentiated vulvar intraepithelial neoplasia also known as VIN Simplex: is associated with vulvar dermatoses such as lichen sclerosus. It is associated with atypia of the squamous epithelium. Risk factors
The exact cause of VIN is unknown. Studies are being done to determine the cause of VIN. The following factors have been associated with VIN:

HPV (Human Papilloma Virus)
HSV-2 (Herpes simplex Virus - Type 2)
Smoking
Immunosuppression
Chronic vulvar irritation
Conditions such as Lichen Sclerosus

Diagnosis
The person may have no symptoms, or local symptomatology including itching, burning, and pain. The diagnosis is always based on a careful inspection and a targeted biopsy of a visible vulvar lesion. The type and distribution of lesions varies among the two different types of VIN. In the Usual type VIN, seen more frequently in young patients, lesions tend to be multifocal over an otherwise normal vulvar skin. In the differentiated type VIN, usually seen in postmenopausal women, lesions tend to be isolated and are located over a skin with a vulvar dermatosis such as Lichen slerosus. Prevention
Vaccinating girls with HPV vaccine before their initial sexual contact has been claimed to reduce incidence of VIN. References
