Vulvar intraepithelial neoplasia (VIN) is a precancerous condition of the vulvar skin. This condition is caused by changes in the cells of the vulvar tissue that allow them to grow abnormally. Vulvar intraepithelial neoplasia can progress to invasive cancer of the vulva. This happens in only about 4% of cases and usually progresses slowly.
Causes and Symptoms
Some patients may be without symptoms or complain of itching or burning. You may also have raised brown, red, pink, white or gray lesions of various colors.
The exact cause of VIN is unknown, but doctors have linked the following factors with the condition:
- Human papillomavirus
Diagnosis and Treatment
Our doctors will either do a colposcopy or biopsy to diagnose vulvar intraepithelial neoplasia.
Treatment options vary depending on the extent of the lesion, the degree of the disease and the presence of other medical problems. Some of the options include:
- Topical chemotherapeutic agents
- Laser ablation
- Surgical excision
Since this disorder may reoccur and it may not produce any symptoms, it is important to have regular checkups.
