what is the pathophysiology of axillary polymastia?

[Howard Rosenberg, MD]

This forum is not appropriate to go into the details of the embryology and pathology of supernumary breast tissue.  Suffice it to say that ectopic breast tissue can occuralong the "milk line" of embryonic breast tissue development, including the axilla, in a per cent of both male and females.  In very rare cases, tumors have been found to occur in this tissue.
