Case report: Ectopic nipple on the sole of the foot, an unexplained anomaly

Supernumerary nipples are common congenital anomalies, most often occurring along the embryonic milk lines. We present a patient with an ectopic nipple on the foot. We are unable to explain the aetiology of this anomaly; however, several theories have been proposed. They are also associated with disorders of the renal and cardiovascular systems as well as pathology that affect normal breast tissue.
