Vulvar fibroadenoma: case report

Abstract

Fibroadenoma is a benign neoplasm usually located in the breast. Its vulvar location
is extremely rare, with few cases published. Its origin is uncertain and highly
debatable, as it is thought that it may originate from vulvar ectopic breast tissue or
from anogenital glands similar to normally existing breast tissue. An unusual case
of vulvar fibroadenoma is presented in a 29-year-old woman who for two years
presented with a vulvar lump that caused dyspareunia and postcoital bleeding.
At the level of the labium majus of the vulva, a well-demarcated tumor measuring
3 x 2 x 2 cm, whitish, with a firm consistency was excised. Microscopy showed a
fibroadenoma which by immunohistochemistry showed positivity for estrogen and
progesterone receptors.
