A supernumerary nipple is the aborted beginning of an additional
nipple along the mid-clavicular line of the thorax. The
hyperpigmented macule may have features more or less descriptive of
a fully formed nipple, and occur a couple centimeters below the
usually placed nipple. They are most often singular, and
unilateral.
