Supernumerary nipple
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.
