title: Breast carcinoma in situ in a male. Report of a case diagnosed by nipple discharge cytology.
abstract: BACKGROUND
  Cytologic evaluation of abnormal nipple secretion is a well-established method for the rapid diagnosis of breast carcinoma in females. However, less attention has been focused on male patients presenting with nipple discharge.
  
  
  METHODS
  A case of intraductal carcinoma of the male breast was diagnosed by nipple discharge cytology alone.
  
  
  CONCLUSIONS
  This report illustrates the usefulness of nipple discharge cytology in the diagnosis of early breast carcinoma in males.
