Intraepithelial carcinoma of the vulva with extension to the anal canal.

Ten patients with intraepithelial carcinoma of the vulva that extended to the anus were studied. The patients were seen and treated over a 3-year period, from January 1976 through December 1978. During the 10-year period before 1976 the authors had encountered no patients with this problem. Treatment consisted predominantly of a skinning vulvectomy with split-thickness skin graft and excision of the anal disease. Failure to recognize the extension to the anus will result in persistent disease following surgical therapy.
