Thirty six patients with Paget's disease of the vulva were reviewed. The median age of the patients at diagnosis was 67 years (range: 45-91 years). One patient had a history of previous mammary adenocarcinoma. Screening for malignancy revealed two colonic tumours. Two patients with negative screening at presentation developed, 12 and 18 months respectively after vulvectomy, an ovarian carcinoma stage IIc and a cervical and urethral adenocarcinoma. All patients were treated by surgery based on extent of the disease. The operations performed included total vulvectomy (n = 11), partial vulvectomy (n = 14) and wide local excision (n = 4). Out of the 36 patients, 29 were available to follow-up. The median follow-up period was 74 months (range 2-204 months). Three patients died of metastatic disease due to vulval adenocarcinoma and breast carcinoma, or of liver metastases from an unknown adenocarcinoma. Eighteen of the 29 patients followed up remained free of disease. Five out of the 16 patients with positive margins recurred, as did 5 out of 9 patients with negative margins. Treatment of Paget's disease of the vulva is surgical. In order to prevent recurrence, some authors have proposed surgical excision extending beyond the visible clinical lesions with intraoperative frozen sections. The data we recorded show that free margins do not seem to correlate with recurrence, so that large excision beyond the clinical lesion is not useful.
