Vulvar fibroadenomas are sporadic lesions informed in the literature and a controversy about origin has been discussed widely. We report a case of a 19 years old woman with a large slow growing mass in the right labia majora with the final diagnosis of fibroadenoma with mammary tissue surrounding it and positive hormone receptors. In this case, we support the origin in ectopic mammary tissue.

外阴纤维腺瘤是文献中报道的散发性病变，关于其起源的争议已被广泛讨论。我们报告一例19岁女性病例，其右侧大阴唇有一个生长缓慢的大肿块，最终诊断为纤维腺瘤，周围伴有乳腺组织，激素受体呈阳性。在本病例中，我们支持其起源于异位乳腺组织。
