Mammary-type fibroepithelial neoplasms of the vulva: a case report and review of the literature.
Mammary-type fibroepithelial neoplasms of the vulva are rare lesions of uncertain histogenesis. Origin from ectopic breast tissue and from anogenital glandular tissue that shares similar histologic homology with breast tissue has been postulated. We report the case of a 45-year-old woman who presented with a vulvar mass of several years duration. Excision of the lesion and subsequent histologic examination showed a mammary-type fibroadenoma with apocrine change. No ectopic breast tissue was identified outside the lesion. The theories of histogenesis of these neoplasms and additional cases of mammary-type lesions of the vulva reported in the medical literature are reviewed.
