title: Galactocele as a changing axillary lump in a pregnant woman.
abstract: OBJECTIVE
  We report a galactocele as changing axillary lumps in both axillae.
  
  
  METHODS
  36-year-old woman visited to our hospital for her axillary lump. The diagnosis could be made under ultrasound examination and her recent pregnancy history. However, sonography-guided aspiration was done for confirmation.
  
  
  RESULTS
  We could confirm the galactocele arising in axillary accessory breast tissue.
  
  
  CONCLUSIONS
  Clinical information indicating that such a palpable mass is associated with pregnancy as well as its sonography features along with adjunctive diagnostic aspiration, can help to correctly diagnose this rare entity.
