| pubmed-article:12769398 | pubmed:abstractText | Supernumerary nipples (SNs) are relatively common, minor congenital anomalies. SNs usually arise within the embryonic milk lines, but they have been known to form elsewhere. The prevalence of SNs varies, depending on the population. SNs are normally benign entities, but they are susceptible to hormonal changes and disease processes and may signify internal disease. | lld:pubmed |
