ABSTRACT This original article tells the tale of the axillary tail of the breast. Human breast`s parenchymal extension into the axilla is known as the axillary tail of the breast. Normally, it remains confined as per the healthy individual’s body habitus. But sometimes it may become prominent and thereby a cause of tension. A plethora of findings have been reported to occur in an axillary tail. From toxoplasma to tumors, the list is comprehensive. Hence, each individual with a prominent axillary tail has its own tale to tell as has been explained in this article. Pathologists as well as Radiologists should be well aware of the various normal and abnormal entities affecting it, so that the distressed individual seeking assistance is properly managed.
