title: Sonographic features of primary breast cancer in men.
abstract: OBJECTIVE
  The imaging studies of eight men with proven primary breast cancer and preoperative sonography and mammography were reviewed and correlated with final pathology reports.
  
  
  CONCLUSIONS
  There were five cases of invasive breast carcinoma and three cases of ductal carcinoma in situ of the papillary subtype. All three cases of papillary ductal carcinoma in situ showed cystic features on sonography. Most (4/5) invasive cancers were solid on sonography. The appearance of a complex cystic mass in the male breast on sonography should suggest the possibility of malignancy and therefore warrants biopsy.
