title: Treatment of vulvar intraepithelial neoplasia 2/3 with imiquimod.
abstract: OBJECTIVE
  To retrospectively review the charts of 13 women diagnosed with vulvar intraepithelial neoplasia (VIN) 2/3 treated with imiquimod and to evaluate the efficacy of this treatment.
  
  
  METHODS
  Retrospective review. All 13 women were treated and evaluated by a single gynecologist. The extent of the lesions prior to treatment and the extent and degree of improvement were documented. Biopsy confirmation of disease was obtained for each individual. Response to treatment was categorized as complete regression, at least 75% regression or not improved.
  
  
  RESULTS
  The mean duration of treatment was 3.3 months, and follow-up after completion of therapy was 5.5 months. Eight of the 13 women had complete regression of the VIN. Four patients demonstrated 75% regression of disease, and in one diabetic woman no improvement was seen. In two women demonstrating 75% lesion regression, invasive carcinoma of the vulva was found in the area of residual disease. In one instance this was determined to be superficially invasive squamous cell carcinoma (1 mm of invasion), and in the second an anal tag was found to have invasive squamous cell carcinoma.
  
  
  CONCLUSIONS
  Medical management of VIN 2/3 with imiquimod is worth considering. However, careful evaluation of the patient must be carried out prior to the institution of therapy to exclude the presence of invasive squamous cell carcinoma.
