Vulvar fibroadenoma: case report

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.
