Multiple vulvar lactating adenomas

Eung-Seok Lee et al. Obstet Gynecol. 2011 Aug.

Abstract

Background: Ectopic breast tissue is defined as glands located outside of the breast. Ectopic breast tissue should be excised because it may develop benign or malignant pathologic processes. Although lactation changes can occur, lactating adenoma in the vulva are extremely rare.

Case: We report a case of a young woman who presented with multiple vulvar masses during her pregnancies. The masses were excised, and histology confirmed multiple vulvar lactating adenomas.

Conclusion: Vulvar lactating adenoma may be misdiagnosed as adenocarcinoma in frozen diagnosis and aspiration cytology if breast tissue is not anticipated. Although the incidence of ectopic mammary tissue of the vulva is low, this possibility should be considered when evaluating patients with mass lesions of the vulva in the appropriate clinical setting.
