Supernumerary Nipple or Pappiloma?

Abstract

Supernumerary nipples can be found in approximately 1 % of women. During the second and the third months of embryonic development when the regression of ectodermal thickening of mammary line takes place, incomplete regression with remaining of some foci may occur. These foci can further develop into a supernumerary breast or a supernumerary nipple. In this article, we would like to present five cases of supernumerary nipples. In 80% of cases, there was a single unilateral supernumerary nipple located along the right mammary line. In all the described cases this minor defect was efficiently excised for cosmetic purposes.
