title: The outcomes of patients with positive margins after excision for intraepithelial Paget's disease of the vulva.
abstract: OBJECTIVE
  Vulvar Paget's disease is a rare neoplasm that usually occurs in postmenopausal women. Treatment with surgical excision can be complicated by extension of microscopic disease in an irregular manner well beyond the visible margins of the lesion. The objective or our study was to analyze the outcomes of patients with primary vulvar intraepithelial Paget's disease who had positive microscopic margins after primary excision.
  
  
  METHODS
  We reviewed the records of all patients with Paget's disease of the vulva treated at our institution from 1/80 to 9/02. Patients whose sample showed stromal invasion or an underlying carcinoma were excluded. Data were collected regarding patient demographics, disease location, treatment, surgical margin status, additional treatment, and clinical outcome.
  
  
  RESULTS
  The medical records and histopathologic specimens of 28 women with intraepithelial Paget's disease of the vulva were evaluated. Surgical treatment consisted of radical vulvectomy in 3 patients (11%), simple vulvectomy in 18 patients (64%), and wide local excision in the other 7 patients (25%). Of the 20 patients with microscopically positive margins, 14 (70%) developed recurrent disease and the remaining 6 (30%) are disease free. Of the 8 patients with negative margins, 3 (38%) developed disease recurrence and the remaining 5 (63%) are disease free. With a median follow-up of 49 months (range, 3-186 months), there was no correlation between disease recurrence and margin status (P=0.20). Of the 17 patients who recurred, 14 (82%) underwent additional surgical excision and 1 patient was treated with Retin-A. The remaining 2 patients refused further treatment and were lost to follow-up. In those patients who underwent surgery for recurrence, between 1 and 3 re-excisions were performed. Of the 15 evaluable patients who were treated for recurrent disease, 12 (80%) had no evidence of persistent disease and 3 (20%) had persistent disease at a median follow-up of 63.7 months (range, 18.5-186 months).
  
  
  CONCLUSIONS
  Microscopically positive margins following surgical excision of vulvar intraepithelial Paget's disease is a frequent finding, and disease recurrence is common regardless of surgical margin status. Long-term monitoring of patients is recommended, and repeat surgical excision is often necessary.
