Abstract:
Supernumerary nipples and supernumerary breast tissue are often dismissed as cosmetic curiosities. These structures have the potential for pathologic degeneration and may be associated with significant congenital abnormalities. In a prospective comparison of 100 Native American women to 100 non-Native American women, these accessory organs were found much more commonly in Native American women. Careful attention should be given to thorough evaluation and long term follow-up of any patient in whom this anomaly is found.
