title: An uncommon urologic presentation of a supernumerary breast.
abstract: Polythelia and polymastia are common developmental abnormalities of the breast and nipple which usually present as small lesions along the mammary line, an embryologic line that extends bilaterally from the axillary regions to the inguinal ligaments. These lesions have been reported in various locations outside the mammary line. We report an unusual location of polymastia in the perineum of a newborn male. A brief discussion of the clinical relevance of such lesions is also included.
