Vulvar lactating adenoma associated to a fibroadenoma: common neoplasms in an uncommon site

Abstract

Ectopic breast tissue is defined as glands located outside of the breast. Ectopic breast tissue should be excised because it may develop benign (fibroadenoma) or malignant pathologic processes. Less than forty cases of fibroadenomas have been reported in the literature. Although lactation changes can occur, lactating adenoma in the vulva are extremely rare. Only four cases have been reported. We report a case of a young woman who presented with vulvar mass during her lactation. The mass was excised, and histology confirmed vulvar lactating adenoma associated with fibroadenoma. This is the first case of vulvar heterotopic breast lesion associating lactating adenoma and fibroadenoma.
