Fibroepithelial polyps with atypical stromal cells (pseudosarcoma botryoides) of vulva and vagina. A report of 13 cases.

Thirteen cases of female genital tract fibroepithelial polyps containing atypical stromal cells are described, eight arising from the vulva, a site of origin not previously reported. These tumours must be differentiated from sarcoma botryoides, which they resemble both grossly and microscopically. Although fibroepithelial polyps are benign, two of our cases recurred after incomplete excision.
